As the title implies: I want "a button" that can reopen the Captive Portal page, for instance when I accidentally swiped away the notification upon connecting to whatever wifi it is that I'm connecting to.
So is there any app, Magisk/Xposed module or anything else that can offer such "a button"?
Well that’s an uncommon topic and you can just create a button using More Shortcuts ( https://play.google.com/store/apps/details?id=com.ss.moreshortcuts) to create a shortcut to turn WiFi off and on to reconnect tot he same network with the notification re-popped up.

Yeah, that doesn't always make the notification reappear. The "usual" experience I'm having is that the notification no longer reappear even after turning wifi off and back on, it rarely works that way.
The definitive and only solution that works (for me) all the time is to first turn my wifi off, secondly reboot my phone and lastly turn my wifi back on.
Hence the reason I'm bringing this topic here to (hopefully) eliminate the hassle. Moreover it just irritates me that there doesn't seem to be a dedicated button that can always open the captive portal interface.
Likely depends on how long the given IP is leased to your device(your phone's wifi Mac address usually) the portal is hosted by the network your connecting to this network also decides what traffic gets redirected or not. Its all or nothing with captive portals, you pay/agree to get access or are provided with terms and given a way to to agree or pay. Its not something the client(your phone) has much control over, that would defeat the purpose. If you have root, changing your mac address will likely trigger the portal. A captive portal is a special wepage hosted on a local server. Depending on how its set up, you can find the local ip and port its hosted on. Look up look up your gateway address in wifi settings, it will likely use a special port as well. In your browser, enter the gateway address, much like opening up the settings page of a wireless router. For example 10.0.0.1 is a common address for router settings, a colon : and the numbers following specify the port in chrome or Firefox and many others. I made a portal for my hotspot on my phone. Its hosted on 10.0.0.1:9090 if your on my hotspot and enter that in your browser, my portal will show. An app like fing would find the ip/port combo for you. It may not label it as a portal, but it will be within the subnet(similar address) of the gateway adress, most likely. Another way to get the address(easiest for sure) is to ignore the system captive portal popup, and instead attempt to visit a site in browser, some sites will still work without ssl which will trigger a browser warning. meetme.com is one such site. I use that website to trigger the portal for McDonald's wifi. The "Button" you want, may be bookmarks in your browser of captive portals you find on networks you use.

I have created an SOCKS proxy server application to run on Windows Mobile phones. A SOCKS proxy is a proxy server that is capable of forwarding nearly all types of network traffic, similar to a NAT router. It is very simple to use. Simply type in the port you would like the proxy server to listen on (defaults is 1080), then click the large "Start Proxy" button.
In order to run this application you will need the .NET Compact Framework 3.5 installed on your device.
Some applications are SOCKS-ready and others are not. You can use FreeCap (freeware) to SOCKS enable any Windows application. ** FreeCap seems to have problems connecting to SocksProxy. Let me know if it works or doesn't work for you. **
I am *NOT* responsible for any fees charged to anyone for the use of this software. There is no warranty and no guarantee.
[UPDATE 2/25/2009]
I've completed the new version of SocksProxy. It implements socks version 4a. There is no security, so it will allow anyone to connect with any user id.
Please let me know of any issues you find.
[UPDATE 2/24/2009]
SocksProxy v1.0 Reboot
--------------------------------------------------------------------------------
I've completed the new proxy server. It looks pretty much like the old one, but I've anchored the controls to the edges so it should scale properly with VGA devices.
I've written a new Socks 4a proxy from scratch and completed ditched all the old code. It seems to be working pretty well, though a bit slow. I think I need to increase the size of my read buffers. I will have to write a smarter heuristic for determining the size of the buffer per connection though. I have them at 128 Kb now. I need to grow each buffer dynamically according to how it's being used, that way I don't create large buffers for connections that are only transfering small amounts before closing (downloading a small gif or javascript file, for example).
I'll probably release it tomorrow after some more testing.
BTW: I'm posting this through the proxy right now!
[UPDATE 2/24/2009]
I've decided not to move forward with the J2ME version of SocksProxy. I will however be writing a new .NET CF version. The current version's proxy is based on code I ported from a proxy targeted to the standard .NET framework. Some features in the standard framework are absent in the compact framework. When porting the proxy I pretty much just did it as quick and dirty as I could because I really wanted something that just got the job done. I didn't care how stable or 'good' it was because I hadn't even intended on releasing it to anyone. Since it looks like there's still a lot of interest I will be writing a new one from scratch. Don't expect too much; It'll be the simplest thing that possibly works, but it'll be stable and reliable.
I'll be naming this version SocksProxy 1.0 Reboot. I'm not upping the version number because I'm really not going to be adding any new features.
[UPDATE 11/4/2008]
I am working on a J2ME version of this application. I will no longer be maintaining the .NET version of the application. The SVN repository for the .NET version will continue to be available. I have no plans on taking it down.
I have decided to switch to J2ME because I will be able to reuse source code in a future Android release -- that is, if Google or someone adds the ability for Android to have more than one IP address.
[UPDATE 10/27/2008]
There is a usage issue with the application with certain configurations of Windows Mobile and Activesync. It seems that when the Activesync host (your PC) has a connection to the internet the handheld device will prefer to connect to the internet via the PC's connection rather than its cellular connection. This completely eliminates any benefit to using the proxy. Does anyone know how to prevent the handheld from routing its internet traffic back through Activesync? Note that this is NOT solved by setting the "Allow data connections" setting in Activesync.
[UPDATE 10/27/2008]
I have updated the SVN respository (https://pchasco.homedns.org/svn/SocksProxy/trunk). Here are the changes:
* Changed "Listening on" box to list all IPs on the handheld
* Added an IP box. Enter an IP to listen on that IP or leave blank to listen on all.
* Rearranged form
* Added "Use selected IP" button to insert into the IP box the IP selected in the list of available IP addresses.
You can enter any IP address in the IP box, but the proxy will fail to start if the IP is not valid for your device.
Hi pchasco,
Could you explain a bit more what this does (and how it works)?
The reason I ask is that I'm looking for an application for the PPC which allows me to share its internet connection by pointing the Desktop browser' proxy to the PPC.
This allows me to be connected to the wired network and using this proxied browser to browse even the blocked sites ...
Can your application be used for this?
If so could you also explain how it works..
I've ran the App on my PPC, and clicked start, this gave me an IP address
next i hooked it up to USB and pointed IE's proxy to that address...didn't work
I also tried to activate the 3G first and/or with ICS activated
but both times I didn't see a IP address...
I'm probably doing something wrong..
Thanks
This is a SOCKS proxy, so it does not work in quite the same way that a normal HTTP proxy does. For internet explorer you'll have to open the advanced proxy options and fill in the information for the SOCKS hostort entry.
Can someone please explain a sample usage of this software on Windows Mobile?

I am not sure why you would need to use both SOCKS proxy and ICS at the same time. They are both means to provide internet connectivity through your phone to another device. If ICS were an option on my phone, I would use it over SOCKS unless the client device did not support it.

Basically, I'm trying to allow access to two networks at the same time. So I want to adjust my settings in firefox to point to my WM phone and your socks proxy. Then my other applications and IE can use my LAN. Otherwise, to get my WM ICS to work I have to disable my LAN connection which I need for certain apps.
edit... I'm good with using it without ICS, but that doesn't seem to work either. No matter when I click start proxy, I get an IP of 0.0.0.0 and if I connect my computer via USB I can't ping that address.

Then setting the SOCKS proxy setting without setting any other proxy settings should work in Internet Explorer. I've been trying to test it, but my phone refuses to access the internet through the cellular connection right now; it's always going through my PC while activesync is connected. I can't get it to stop! The funny thing is IE on my PC is making its HTTP requests through my phone, then my phone is going right back through my PC to the internet!

I think there is a setting in ActiveSync that says "allow wireless connections when connected" sounds like that might be your problem.

Sounds like the same thing that is happening to me. I finally got it to give me an IP address, but only if my data connection is inactive. As soon as the data connection is active it becomes a 0.0.0.0 IP address. Bug?
I tried to establish the IP, then activate the data connection... still doesn't work when I enter the IPort into my proxy list for firefox.

I am not sure why you are receiving 0 as your IP address. Check in Settings->Connections->USB to PC that "Enable advanced network functionality" is selected.

removed the AS connection, started the application
It showed me the IP address op 127.0.0.1 (localhost)

Hmm... I'm not sure what's going on here. 127.0.0.1 is the loopback interface-- It is only valid for your phone to connect to itself. If your computer attempted to connect to 127.0.0.1 it would connect to itself, not your phone.

Well, if I have time in the next few days I will take a look and see whether there is anything I can do. Maybe there is another IP address available on your device but for whatever reason I'm displaying the loopback instead of the external interface.

If you can't use ICS and want to connect to the internet from your desktop, you can connect your phone using USB and start this proxy, then you can setup your desktop connection to use the proxy to get internet access.
I didn't get much response on my previous question about proxy support for the stock rom, so I was wondering if any of the alternate roms include it. I would very much like to have access to the internet at work, but the school district requires loggon through a proxy server (content filter) before you can access the WiFi network. I realize that port restrictions that the district places on the network will likely prevent me from accessing the market, gmail, or voice search. But at school, I would most like to just access flash based educational website for kids.
Any thoughts on this? The district is moving toward ipads as the tablet platform of choice because of the lack of proxy support with Android. But the ipads lack of support for flash really hinders what I want a tablet to be able to do for me. (Yes, I want my cake and eat it too!) Is this too much to ask?
I connect my gtab to my schools wirelesss that is using 802.1x EAP for wireless security. I had to install a mod that changed the settings app and allowed advanced wireless settings. That allowed me to put in the authentication type, domain name, password, etc. Once connected, I ran a mod that set it back to the original settings apps. I asked in your previous post as to whether you are having problems actually getting on the wireless or once on, you can't bet by the web filter. We use websense here. Once I got on the wireless, there was an websense authentication dialog that popped up. Once I put my domain\username and password in, it works fine.
It won't even let me connect to the district network because I don't have anywhere to enter the proxy settings in the wifi set up box.
Assuming you have Pershoot's or Clemsyn's Kernel (or one of the better ROMs), you need something like ASProxy. I use it at work all the time and it does the job. There is a free program called TransParentProxy which is more limited but does allow you to quickly test settings without spending any money.
I do not see a proxy settings in the wpa_supplicant.conf file. My understanding of this file is it lists all possible settings settings available for Wi-Fi configurations.
# This file describes configuration file format and lists all available option.

Previously I've only needed to access a proxy after connecting to the network. Perhaps you have run into a problem getting connected to your network using the tablets Wi-Fi settings manager. So connecting to the network might be your first step and then connecting to the proxy your 2nd.
I found the free Wifi Advanced Config Editor (WifiACE on the Android Market) to have a GUI to easily configure advanced Wi-Fi settings not found in the tablet's settings. I realized when trying to set up an advanced configuration I needed to create a new connection in the tablets WiFi Settings with the security of NONE to avoid having some of the wrong settings configured by default. Then using the information from the my network admin I manually set the options via the WifACE GUI, un-checking NONE, and bingo I got connected.
I recommend WiFiACe with one caveat: make sure you have a way (like adb) working and know how to backup, delete, and restore files and that you make a back up of all wpa_supplicant.conf files on your tablet.
My caveat comes because my first reboot after I got connected to the Enterprise network at work the Wifi would not start or run. It would only display "error" and do nothing. Several reboots later it still wouldn't start and without Wi-Fi running there is no way to make configuration changes either through WifiACE or the tablets Wi-Fi Settings. I had to use the adb shell to delete the newly configured wap_supplicant.conf and create a new connection via the tablets Wi-Fi Settings and then make the necessary changes through WifiACE. Once that was done it ran and connected. Now after multiple reboots it still works and connects. Without the ability to delete the file I'm afraid I would have had to re-flash my tablet to get Wi-Fi to work again.
I don't think you've ever mentioned what ROM you're running. If you're running stock, you will have a very difficult time, in fact it may be impossible. If you're running a different mod, there's hope. Now, assuming that you got ClockWordMod (CWM) installed, you can probably be successful in at least connecting to the wireless. If you don't have CWM installed, here's a good place to start:
http://forum.xda-developers.com/showthread.php?t=865245
Once you have CWM installed, go to this thread:
http://forum.xda-developers.com/showthread.php?t=857939
This will give you the zips for installing a differernt wireless config tool that will allow you to put in the 802.1x EAP config. Once you can successfully connect, you back out the the tool you installed.
I have an mpman mp824 tablet (same as Coby Kyros MID8125), preloaded with Android 2.3.3. I want to use a VPN, but when I go to the Settings - Wireless and Networks screen, there is no VPN setup item as I would expect. I'm not an expert, but I assume this may be because a) the VPN applet is there somewhere, but has not started, or b) it is not there for some reason.
Can anyone help, plus is there a way I can overcome this? I have tried the supplier, but they are not replying
Thanks in advance for any advice.
Try these steps. It will surely help you!
1-Tap the ‘Menu’ button on your smartphone to open the resulting window.
2-Open the ‘Wireless and Network Settings’ window as you enter the new window and tap the concerned icon.
3-You will notice the option for ‘VPN Settings‘ along with many other options depending on the interface of the respective android vpn phone.
4-After tapping the VPN settings option, you will get the choice to connect to one of the many protocols available. From these, choose ‘Add PPTP VPN’.
5-In the next window, you will be asked to set VPN Name, VPN Server, Enable encryption, and DNS search domains, depending on your handheld devices.
6-Provide VPN Name and other information accordingly, click OK to complete the VPN configuration.
7-Navigate back to the VPN listings window and tap the VPN network that you have created just now to establish the connection.
8-The connection will be notified by a key icon in the notification area of the smartphone.
9-To disconnect the VPN, all you need is to move to the location of the connection and tap the current VPN connection.
Hi everyone,
I am trying to get my head around on what can be done to bypass the tethering filter on 3UK.
Below are different scenarios I have come up with and would like any volunteers who could try out any of the following for me. Of course I will be doing these myself as and when time permits but its always helpful to have others view on it too.
Please and I say please, do not turn this thread into Right and Wrongs of tethering or Terms and conditions of 3 mobile contracts. Please keep your views to yourself regarding if its lawful or unlawful or ethical or unethical or whatever you seem to come up with. I would like this to be a productive thread, instead of random comments on tethering.
Option 1: Use SSH Tunnel * Should I use SSH tunnel on my phone and use my PC to connect to it to use internet. Is there a reverse option?
Option 2: Use OpenVPN Install OpenVPN on your pc, and connect your phone to your pc using default VPN function on your phone in my case GT-I9100 comes with VPN function. You could also try to reverse this method and install OpenVPN on your phone and use your PC to connect to it. *
Option 3: Use the above two together in combination As the heading says, use SSH tunnel to connect to your OpenVPN.
Option 4: Use a proxy on your pc and connect to your phone or reverse, install proxy app on your phone and point your pc web browser to that proxy address. You could use the SSH tunnel here to connect too.
So, tools at hand are vpn with any encryption available, ssh tunnel, proxy server.
Tools to ignore - TOR (onion), garlic based TOR like, changing User Agent on web browsers or paid VPN.
3 UK has two APN settings, three.co.uk for mobiles (NATd ip address) and 3internet (dongle users) has external IP address and I believe it’s an Open NAT or no NAT.
Please feel free to mix and match any options and also share your views on what is technically possible.
I hope to see something useful and learn a bit more. Even if we fail to achieve the desired results, it will still be enlightening to find the facts on how 3 detects tethering.
I
Code encode decode
Found on giff gaff forum useful info
Well, they have a few ways..TTL: In my opinion, the most likely telltale signal of tethering. For example, *iOS packets originate with a TTL of 64, so if they see anything else they know something is up. This is very easy to check, as the TTL is checked by each router as the packet is handled. (the address on the envelope - doesn't require opening the letter, to use an analog analogy)APN: Another possible sign of tethering is data being routed over the access point set up for the built-in tethering feature. But giffgaff does NOT have a separate APN for Tethering. Again, this is easy to check without deep packet inspection.User-agent: This is where carriers would need to get heavy-duty equipment and a willingness to be invasive to detect tethering. Your browser sends information about itself to remote web servers, and this information could be checked. I do not think giffgaff is doing this (to detect tethering at least,) as it is not proof of tethering since anyone can easily use another browser on your phone that reports a different User Agent.Web Sites Visited: Again, highly invasive, though it doesn't require DPI. If you're using the DNS servers of the carrier, they could look for requests for certain domain names like windowsupdate.com etc. This wouldn't be proof either, though.I would bet that they are using TTL. So tunneling the TCP/IP packets that way probably resets the TTL to the default of the WAN interface on the phone.
Code encode decode
Why do you have to make 2 threads for the same subject?
Well I wasn't sure at the time of writing first one if I had to go down the route of testing which the second one is for. So, the first one is literally to know if its happening to new contracts only and second is for testing different scenarios and finding how.
Hope this helps and if not then jog on.

For 3 days I've been trying to fix the 'unstable internet connection' on my phone to no avail. Finally I found a fix. This hasn't been listed anywhere I've seen and I've been researching this non-stop for days.
Go to your wifi connection and see what your IP address is. Then check your other devices. The IP address on the phone I was having the problem on was different from every other device in my house.
THE FIX
Choose your wifi network, tap and hold it. Choose modify. Then choose 'show advanced options. Under proxy settings choose manual. Under IP settings coose Static. You'll now be able to manually enter your IP address. As for the proxy host name, proxy port, and bybass proxy for, I just entered something random.
When I restarted my phone for the first time the 'unstable connection' part came back and I had to disconnect and reconnect and it was fine again.
Hope this helps people until we get a fix.

Does this work if you're on a dynamic IP network? What about if you're switching regularly between open and closed networks? This perhaps resets the WiFi. I've looked at advanced settings before, but this happens with mainly open networks, and I believe that these typically have dynamic IP addresses. The protected network in my home is rarely an issue, but open networks are what give me fits.
No harm in trying, and if it works, that'd be awesome. I'm wondering if done once it fixes all such issues that one encounters, or must be done with every new network.
@freeza has a fix in the works in the form of a kernel, and so far, it's pretty solid. The only issue I've found is that if ya flash anything, you have to reflash the fix. Odd, but does the job.

For this to really work, you'd need to do more than the OP states. ALL basic home routers/access points come setup with DHCP (dynamic host configuration protocol) which assigns IP addresses from numbers it keeps in a "pool". If you manually force your phone to use an IP (lets say 192.168.1.15) then leave the network (you go on some business trip) - and in the mean time, one of your kids adds some other device, or simply reconnects a device that hadn't been on the network for a while. After a certain period (the "lease" period of the IP), the router will put that IP BACK into the pool of available IPs. And since nearly all routers assign IPs bottom up (lowest to highest), if 15 is the next available number - you're toast. You come home, your phone tries to connect on 192.168.1.15 and gee- sorry - your son's PSP is on that IP.
For this to be a workable long-term solution, you'd have to enable static IPs within the router (a better way to do it anyway - that's how I have my network setup). You would simply go into the router, and tell it which IP to give to a device based on that device's MAC address.
Just figured I'd throw this out there because if an IP collision happens, the 2nd device in will simply get nothing - don't want someone tossing their phone out a window when it suddenly won't connect to a home network.
