[Q] Blocked from connecting to my home wifi. - Android Q&A, Help & Troubleshooting

Hey guys,
My Father changed something in the router settings yesterday which blocked only me and my brother from connecting to the Wifi.
Anyone else can connect normally and gain Internet access. It is a password protected access point but I have the password and I entered it correctly and it connected but it says "Authentication error occurred".
Does anyone have an idea of what he blocked? Mac address? IP? what? and how can I change it?
Thanks in advance!

Mac address definitely. I would also offer he reserved IP addresses to certain Mac adds & limited number of ip address (i.e., 2 or 3 vs 255). Can you get local access & then access router w/its id name & password?

I have only once changed Mac add & that was inadvertantly & rooted. Don't know if Mac add can be changed w/o root. IP address theory might be tested using a VPN app (may still need connection) or app such as Hide My Ass.
Good luck.
Edit: Now that I think about it, you can't test IP theory w/o outside connection. Sorry.

Can someone tell me where the Mac address is stored in SGS2.
I have found /etc/wifi/nvram_net.txt but in that file it is a different mac address then the one i see in wifi advanced settings.

I really need this information.

I actually thought it was chipware (pic) stored on the actual wifi hardware. I know you should be able to override.
How do I override it?

Dunno, much like linux I would guess, why do u want to?

Not the best of ideas, and may not even work, why not sign in on your phone?
And for your "How do i do in linux?" question, you use goolge to search for a query that millions will have had for the widest used classification of operating system in the world
But... a simple google search gives
http://www.robmcghee.com/android/changing-the-mac-address-on-android/
I am in a hotel and with a pc connect to the hotspot and get a wifi connection:
Then when i start to surf i get redirected to http://hyd.guestnet.int/login/
Where i fill in username and password in a form and i send the information to http://1.1.1.1/logon.cgi.
On my phone i get a wifi connection but is not redirected and i can not surf to http://hyd.guestnet.int/login/
I have tried all ways that is described but none is successful.
That is the reason I wonder if someone knows how i can change the mac in os on a SGS2.
/Mike
you tried downloading opera or firefox for your mobile? Either or may make it so you can login on that form?
Easier solution if it works

Have tried Opera mobile, firefox and dolphin, none is working.
/Mike
Don't forget to set the User Agent of Opera/Firefox/Dolphin to Desktop. Does the hotel ask for a login in the form of a website, or is it a dialogue box? Because websites can easily load on your phone.
I have the Useragent set to Desktop.
The hotel redirect me to a webpage http://hyd.guestnet.int/login/
Where i fill in username and password in a form and i send the information to http://1.1.1.1/logon.cgi.
On my phone i get a wifi connection but is not redirected and i can not surf to http://hyd.guestnet.int/login/
I can not get the phone to show the webpage with login.
Now i was thinking to set the same mac addres on my phone as on the pc and use the pc to logon and then switch of wifi on pc and turn it on on the phone.
/Mike
Is it possible to change the mac address on SGS2?

[Q] Weird wifi issue

Hey guys,
i have an issue with my wifi connection, but only in one specific place.
Here goes: I can connect and use wifi everywhere(without any problem), but not at my friends house. Wifi connects without a problem, but after that i cannot use it (can't download from market, can't surf, etc.). It says there is an internet connection failure, altough i'm still connected.
I know for sure there isn't a problem with routers, modems, networks, etc. coz i setup his network myself (exactly the same as al the other networks i use) So in this there cannot be a problem. My friend can connect his iphone4, my wife can with S+, even a guy with an ACE can connect and use, except for me and my ACE.
Already reset router, modem and phone (even other firmware), but still nothing!
Hope somebody can help with this, coz i'm really bugged out on this one.
Cheers.
Check if u have a WPA protection.. My ACE doesnt work with Wifi with WPA pwd..
or
Try this:
Go to Wifi Settings, select the hotspot you are connecting to, forget the connection, restart ACE, connect to the hotspot again by entering the password
Hope this helps..
While on the topic of not being able to surf, I can never download anything from mediafire.

weirdo wifi
Check on router setting the ip address your phone is using is not bind to another device,s mac address this is on the router settings something like ip & Mab binding.
It could be the ip you are trying to use alocated for use by another device only.
However u will be able to connect to the router it will show in the router you phone is connected and alsoshow in wifi on the phone you are connected but you will NOT be able to connect to the internet.

Hey,
Thnx, will try this ASAP. This might be it.
Question: If my phones ip-adress is indeed the problem, is it possible to change it without any problem? Or should i delete the binded ip at the router?
Cheers.
ip no problem
You can set another ip address manually for phone first find out what routers ip address is
normally 192.168.1.1 is default for lots of routers then see router has DHCP
enabled this means router issues ips to devices. if it is enabled the leave your phone as is and check on the router under ip & Mac binding see if it is enabled UNanble u can always put it back
even better see on router what ip your phone is using then checxk in ip & mac binding that it is not assigned to another device for use. if it is u can delete that binding.
binding means you give a certain device's mac address a certain ip so only that device can you that ip
for example say your phones mac adress is 12:34:56:78:90:00 and you assign or give it ip adress 192.168.1 10 then in theory only your phone can use this ip. THIS not always the case depends on what make router. Whilst we are at that what is your router model.
Look in these places on roter
DHCP settings
IP & Mac Binding.

IP & MAC Binding Help
To manage the computers well in the LAN, you could control access among computers by ARP Binding.
MAC Address - The MAC address of the controlled computer in the LAN.
IP Address - The assigned IP address of the controlled computer in the LAN.
Bind - Whether or not enable the arp binding.
Modify - Edit or delete item.
Link - Turn to IP & MAC Binding Setting page.
Example: If you want assign 192.168.1.4 to PC A (MAC: 00-E0-4C-00-07-BE), and any other PCs could not use this IP,you should first enable "ARP Binding", and add a new item as below.
ID MAC Addrss IP Address Bind Modify
1 00-E0-4C-00-07-BE 192.168.1.4
DHCP ip Address Reservation Help
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the same IP address each time when it accesses the DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings.
MAC Address - The MAC Address of the PC that you want to reserve IP address for.
Reserved IP Address - The IP address of the router reserved.
To Reserve IP Addresses:
Enter the MAC Address (The format for the MAC Address is XX-XX-XX-XX-XX-XX.) and the IP address in dotted-decimal notation of the computer you wish to add.
Click the Save button when finished.
To modify a Reserved IP Address:
Select the reserved address entry as you desire, modify it. If you wish to delete the entry, make all of the entry fields blank.
Click the Save button.

[Q] OpenVPN Routing Problem

Hello
I have installed OpenVPN and its logging on to the vpn and is visible on the network list BUT I dont get any connection to another client in the vpn. I tried to ping another client from my SGS2 and from a client to the SGS2 but its always a timeout. I tried it with the phone and serveral wireless networks.
So I think it could be a routing issue but I dont have a clue how to see if thats really the problem and if its true how to fix it. I read some other posts and maybe it could also be a tun.ko problem but the SGS2 with 2.3.3 should already have installed it on the software, so I'm not sure how to see if thats ok. The Busybox is installed at /system/xbin. So does anybody have an idea how to find out whats actually the problem and how to fix this?
Thanks for your help!
Manolo
It's not clear to me if you tried connecting through your mobile data plan. Did you also tried that?
What is the IP that you are getting when your are connected to the VPN?
If it something like 192.168.1.* Then that's could be your problem. If the WIFI your are on, also gives you an ip adress as 192.168.1.* then that causes the problem. Either change the ip range of your network to 192.168.10* (just an example) or the ip range of you VPN.
ps can you post your VPN server settings?
Do you mean my own ip or the ip that i have in the vpn?
my own edge telekom ip is 10.219.127.35 and my internal vpn ip is 10.10.0.22
I can't post my vpn server settings because i got some key files for the vpn.
If you have installed installed this .zip
http://forum.xda-developers.com/showthread.php?p=16182571#post16182571
Then all you need to do is download openvpn settings from the market. And run in.
If you already did these steps, then the problem lies probably with your server and I need the server config. I don't need the keys of course
Thx!
How does this update work? I see no instructions on the post. Is it just to copy on the root folder?
Ah yes... I found how it goes and its working perfectly!
Thx a lot!

help with wireless ip address

I was wondering if there is a way to change the ip address on your phone? like when i use wireless tether can i change my ip some way?
help plz
Try taking out the battery of the phone nd leave it off for a couple of minutes, this may or may not work because there is a high chance that our phones have a dhcp lease which makes us keep the same IP address for some time.
Now you got to understand that if you want to fool around with the wireless provider IP you might get burned quick, you don't know their network structure nor subjects and dhcp policy; but it also begs my question: why would you want to do this???
Also, if your rooted and have busy box check for the ifconfig command.

Not sure about 4g, but all you have to do on 3g is toggle it off/on. You can't choose the IP, but it will be different.

[Q] work has me blocked anyway around it?

I had a razr maxx and I could connect to wifi at work with the password. Then I could not get on any longer. All it would say is obtaining ip address and never obtain it. Now I upgraded to a note 3 from verizon and was able to access work wifi again but only for about a month then it seems like im blocked again. They have to be doing this from the wifi mac address right?

The guys that run tech support at your work would be able to answer this much better than we could. A lot of it depends on what kind of encryption they use and what protocols they have set up for permission and all that.

if i take my kindle fire hd to work i can connect to the wifi. keep in mind all 3 devices i have been connecting to with the same password. I asked a coworker who works in sales and brings his personal tablet with him and he said he had to provide the address so they wouldnt block him. its either the ip address or mac address

That should be the Mac address then. It's typically pretty easy to see what device is connected in the router settings page and usually displayed by Mac.
Perhaps something of this sort might work if that is the case?
