[Q] Ad hoc wi-fi - network detected, but no internet - Huawei MediaPad, T-Mobile SpringBoard

To enable my rooted ICS (official) Mediapad to connect to ad hoc wi-fi networks, I tried using the method described (and the wpa_supplicant provided) here:
http://forum.xda-developers.com/showpost.php?p=22113766&postcount=24
Happy thing is that now I do see the ad hoc SSID, but it gets stuck, alternating between "Authenticating" and "Obtaining IP address" on the tablet although my Win7 laptop says it's "connected" instead of "waiting...".
DHCP is enabled.
I tried specifying static IP on the tablet and it does get "connected" - but in actual fact, still no internet. The status of the connection on the laptop shows data being sent, but "received" is 0 bytes no matter what I do.
Am I missing anything? Am I configuring the static IP wrong?
Anyone gotten ad hoc wi-fi connections to work?

Don't have a real good answer for you but have you checked the firewall on your laptop it might be blocking the traffic.

Thanks for answering but I did get it to work shortly after my post using the free version of connectify on my laptop doing the broadcast.
Still (*) which means ad hoc wireless, but this time it works!
Edit: this is confirmation anyways that the wpa_supplicant mentioned above works for this device!

htc 8525 cannot connect to internet even after getting IP from router

Hi Folks
With a lot lot difficulty I got this to connect to a WPA-PSK TKIP connection. The router is a netgear - one thats 802.11n capable.
I get IP address from the router so the HTC will show IP e.g. 192.168.1.4
. But the router lists the device as unknown and does not reveal its IP on the router page under "attached devices".
When I try internet explorer I cannot connect.
I did not yet try to change the ROM. Would it matter - what is the ROM.
Initially it would not even connect over a WPA2-PSK connection - though my router supports both WPA-PSK and WPA2-PSK connections.
I am totally frustrated. Can someone help.
Also I tried this too - I FORCED it to take a static IP e.g. 192.168.1.25 and put the DNS IP addresses to that I found on the router that belonged to my ISP . ( what ever DNS the router will show me - and thats given by ISP )
Yet No Luck . I can't get on line even though I can connect to Wi-Fi.
Woaa !!! NOT A SINGLE REPLY ? Could you be so mean ?

[Q] SSH Tunnel - works on WiFi, not on 3G?

I've searched high and low for this, but I can't find an answer.
I am using the SSH Tunnel app on a rooted HTC One S which is otherwise stock. It works perfectly on my home wifi network (if I access an ip web page it shows my SSH server's ip).
If I then turn off the tunnel, disconnect from wifi, reconnect over 3g it connects fine, but when I access the same site it shows my phone's IP, not my servers.
Are there any known issues that prevent SSH Tunnel from working on 3G?
Any suggestions?

S3 can connect to WIFI but no Internet

Hello everybody.
Since last saturday i'm testing a Galaxy S3.
I want to test if everything works properly before buying it.
I have some problems deling with the WIFI stuff.
I gave him a static IP (192.168.1.15), configured the gateway as the ip of my router (192.168.1.1),
the network class is 255.255.255.0 (network prefix = 24), the DNS points to the IP of the Router (192.168.1.1)
It connects without problems. form the S3 i can ping any device in my network and from other devices i can ping the S3.
I can connect to the configuration site of the router and from the page of connected devices i can see that the S3 is connected
with the correct ip and also the MAC adress is correct.
And for now everything is fine.
Problems raise up when i try to surf internet. The answer is always "Page not found"
If i open the browser and try to navigate to google] the answer is "Page not found". Same for any other site i try to connect with.
I cannot ping external adresses from the S3. Only the ones inside my LAN.
On the same LAN there are 3 laptops, 1 IPhone, 1 TV, NAS NETGEAR , home automation screen, all connected in WIFI.
All of them configured in the same way. (static ip, gateway=ip router, dns = ip router, network class 255.255.255.0),
And they all access internet without any problem.
The network is protected with WPA2/PSKey, encryption AES.
I tried to configure channel with WPA, WEP, without protection, but no changes.
The S3 connects to router but does not connect to internet,
I also tried to make it point to a public DNS 8.8.8.8. No WAY!
Works for other devices.
I tried to reset S3 to factory parameters, same thing i did for the router.
I reconfigured everything from scratch but no result.
I do not have any filtering based on IP or MAC adress on my Router.
I tried with DHCP, with reservation of IP adresses or without reservation. No change.
Other devices can access internet. S3 does not.
I have to say i'm quite desperate.
If you guys have some good ideas to solve or diagnostic the problem i would be grateful.
Cheers,
Fabio
I get that around my office as I walk around, I find that when I change AP in range my internet connection drops. I have to constantly disable/re-enable WiFi.
Even around my house, I have the handset to WiFi always on, yet when I wake up in the morning the internet connection is not working yet there is an IP. I couldn't be bothered to telnet to port 80 etc., but I hear that the Jellybean update will resolve this issue.
Same problem

I'm having the exact same problem, I'd really like to know if you were able to solve the problem.

Me too... Is anybody has solution for this issue?
Oh poor fellows ....try to add DNS manually according to your ISP...not add public DNS
Try forgetting the network and connecting again and make sure all the other devices are using different ip address

Wifi connected, no Internet

Hi!
I just got my new Honor 7 and I'm now experiencing a major flaw: I can connect to my WIFI, but won't get Internet connection.
Details:
- Wifi router supports 2.4Ghz and 5Ghz, same error on both.
- IP Configuration (DNS, Gateway, DHCP) set to same as on Laptop and other android devices - all other devices working fine
- When connected to Wifi, Phone can be pinged by other devices & phone can ping other devices
- Phone cannot ping the router but is shown in it's "connected devices" list (correct MAC adress and everything)
- When opening a Wifi Hotspot from my Notebook (forwarding the router's wifi), Phone can connect to internet & ping router (everything works perfectly)
How is it possible that if my Notebook forwards the router's wifi everything works perfect but I can't get it working by connecting directly?
Hope any of you can help me with my problem!
Best regards
Do you use a MAC filter? Sounds like your router blocks the connection.
Gesendet von meinem PLK-L01 mit Tapatalk
Nope, no MAC-Filter in use!
As i said the device gets listet among all other (working) devices in the router's DHCP devices list...
Sounds like a router issue. Any way to check if WiFi works on somebody else's WiFi? Suggest maybe change channels that WiFi is transmitting on the router

The Wifi on the device seems to work fine:
Wifi Hotspot made by notebook works, Public Wifi at Shopping Mall worked fine .. Checking more Networks tomorrow!
\\EDIT: Both Networks at my University work fine.
Is your subnet mask 255.255.255.0 or something else for the gateway? This affects the network prefix length. Also check DNS, try static setting instead of dhcp and use Google DNS 8.8.8.8 and 8.8.4.4

What is Gateway IP address and what is the Subnet mask?

Subnet mask is 255.255.255.0 , according to that prefix length is set to 24.
Can't get DNS , nothing changes when changing to google!
I noticed that when I do an arp scan for the network, I can find other devices but not the router. On my old phone the router will show up on arp scan!
If router can see phone, then assign it static IP address, then add that IP address to DMZ - that way it's fully open. Sadly with routers it's a matter of narrowing down the problem with trial and error to resolve. You can also try temporarily deactivating firewall, and/or temporarily removing WiFi security to see if any difference.

Router can see phone! I have just added it's temporary IP as DMZ Host to check whether it solves the problem - and it does!
When the phone is set as DMZ Host in the router it can ping the router and connect to the internet (so far it seems like any other device).
Before setting the static IP and using this method permanently, I'd like to ask if this causes any changes to other users in the Network ? I am sharing the router with two other people using it for phones, tablets, IPTV etc.
I'm sorry I have no idea what DMZ is exactly.
Thank you very much for your help so far!
No problem. It's not really a permanent solution as it just opens up the IP address to all traffic. It does mean that the router is somehow blocking the phone in normal conditions. This could be for all sorts of reasons, firewall rules on the router, or port forwarding, or Mac filtering, or IP filtering, difficult to say. DMZ shouldn't affect the other users.

I'm not too sure about this router's configuration because it is a rather cheap NoName device provided by the ISP while at my home I'm used to AVM devices.
But I can nowhere spot any specific rules, there's not even a single port-forwarding set on the device. So I can't spot anything that could be blocking my phone :.
Anyway I have just removed my phone from DMZ, reconnected it to the Wifi and so far it's still working fine!
Even if I have to re-do this procedure every now and then after device reboots it shouldn't be a problem.
I have no Idea on how temporary setting it up as DMZ haschanged everything, but for now I'd consider the issue solved! I owe you one for this
Sorry that i have to reopen this old thread but i have the same problem with my HONOR 7.
I have Wifi Connection on my phone but the internet isnt working.
Curious is the fact that this problem only happens in my wifi at home and at my girlfriend (same router and telecommunication provider).At other wifi's everything is working fine.
I hope you can help me.
(sorry for the bad english)

Set the Wifi band permanent anywhere between 1 to 10 and try connecting it.

Tested all 10 channels but still no internet.
Also tested disabling the WPA/WPA2 PSK safety but same result.
Put it in DMZ, find DHCP table and see which IP adress phone get, put that adress in DMZ, DMZ settings are on the same place as NAT (usually). I think that phone cannot get DNS server from router because of some rule in firewall, but try to ping 8.8.8.8 from phone without setting up DMZ, if DNS is problem he should ping that adress but not be able to load page in browser....
@ MaxMonument94 can u connect to any other Wifi ? or all having same issue ?
The internet connection is working in any other network exept the network at my girlfriends place but she has the same router/provider as i have.
If there are any german users, we both got “telecolumbus“ as internet provider.
Now its just more curious.
After i entered the IP in DMZ my ookla speedtest on my phone showed perfect results.
Also the Chrome browser loaded pages and other apps (like 9GAG, Telegram, Whatsapp) worked for a while without any problem.But after a while they all got connection problems (page dont load, waiting for connection on telegram, GIFs dont load).
After that i started a new speedtest and the results were again quite good.
Then the same procedure again and again.
I have really no clue what kind of problem that is.
Btw: my mobile internet was disabled all the time to dont distort the results.
When that happens again, try to ping 8.8.8.8 and tell me what is output, remember ping it when it wont work....
I have pinged 8.8.8.8 with Android Terminal Emulator
The results in the screenshot.
