802.1x wifi problem | galaxy gio

work fine on mine

maybe that router is not compatible .. i have the same problem in some places..

Oi, there is so much that could be going on here...

Its an Atheros AR6003G chip, which as far as i know, supports 802.11 A/B/G/N, and hardware encryption for WEP/WPA...

Odds are, if its an 802.1x type network, the chip will do the encrypting/decrypting after the handshake is completed, provided its set up correctly. WEP and WPA are set up by using a Pre-shared Key that all users need to have... If you study how to recover the key, you'll find that the hash is created by taking the plaintext passkey, running it through the specified algorithm, then salting it with the name of the network. So long as all devices have the correct network name and the correct plaintext password, any device can connect to the network, because they'll all end up with the same hash.

802.1x encryption is different. It uses an authentication server. This makes it similar to any modern computer you log onto. You provide the computer with your credentials, and it checks it against the server. If they match, then you are allowed access. If they don't you get an error message. Which means, that if anything is broken, it won't work. If you don't use the correct authentication protocol, it won't work. If you don't have the right certificates, it won't work.

Best advice I can give is, double check everything. Make sure your Gio has the correct certificates and that its using the correct protocols. Double check your IP/Subnet Mask/Gateway addresses. If you don't have an IP address, you'll have to manually configure it. If the Subnet Mask is incorrect or the Gateway address is incorrect, it won't work either. Also, check your DNS server addresses. If those aren't correct it won't load any webpages using URLs. It will only load them using the IP address of the server. Which means, telling the browser to go to www.google.com won't work, but if you tell it to go to 173.194.67.99:80, it will load the Google homepage.

Hopefully this will give you somewhere to start...

Yes true, only problem is that static IP's dont work, otherwise I could just copy the DNS and gateway numbers from a device it does work on. It uses DHCP and I think that I have the problem you told about.I dont think our school uses certificates cause a friend of my (Galaxy S) can connect without having installed certificates or something.

I think its an hardware isue and it cant decrypt the code well, my WIFI indicator stays white, with internet acces it should turn blue or green.

What if you go to wifi settings- menu button - advanced settings- 'regulier domein' I know you are dutch, dont know how it is called in english, something like regular domain I guess.
Then set it to 11 13 or 14 try them out, fixes my wifi, also at school with 8.11x connection mode

That is very very odd... I use a Linksys WRT54G2 router at home, and its set up for DHCP. Its address is the standard 192.168.1.1, and it can address 50 clients between the addresses of 192.168.1.100 and 192.168.1.149. However, if i set my computer up to use static settings, it works just fine... Granted the networks are probably set up differently.... but the theory should work just fine...


Are you positive it doesn't work?

If you can get me the encryption type, IP address, Subnet Mask and Gateway address your friends phone uses, I may be able to help more... The more information you can get me, the better.

The only reason I can think of that would cause it to not work is that the IP address is already in use, or the Subnet mask is incorrect... It shouldn't matter what IP address you use, so long as the subnet mask and gateway are correct... In theory anyway...

Im on the same school as runedegroot but the neteork does work for me, and i dont think a stattic ip will work cause the network is spread over a lot of routers so if any other phone gets that ip via dhcp it wont work anymore

Well, apparently DHCP doesn't work for him, so whats he have to loose?

Although that's quite interesting... What phone do you use, and whats the network information you have when you're connected to your school's network?

I have the same problem

I'll try, it didn't give me positive feedback when I tried it on MC 7.2, I'll try monday.
Btw, voetbalremco is a dutch name, you also have a dutch thumbnail, but you aint dutch?

Im dutch, but the forum is english so I also post in english, I dont like it neither if people post in polish or whatever I cant read..

I use galaxy gio, gt-s5660. Maybe willie1001 knows it, I can't see it when I'm at home.

Actually that was for willie1001...

And its possible that changing the reguatory domain could work. If you're running software designed for the states, it would disable any channel above 11... But then again, if you can "see" the wireless network in the settings menu, it would make sense that its programmed to use a channel isn't above channel 11... Which would mean that changing the regulatory domain wouldn't help it at all...

Come to think of it, if your MAC address is blocked, it wouldn't allow you access... But then again, you'd have to do something for the school to block your MAC address. And if the other students can access it, then it would have to be specifically you who did something to piss off a teacher.

Also, any information you can get me about the router would help greatly. By figuring out the manufacturer of the router and the model number of the router, its possible to narrow down the likely IP addresses that the router would use..

Haha no, I didn't piss of a teacher
I think it's a gio problem, willie1001 has the galaxy s with cyanogenmod 9.
I have gio with cyanogenmod 9. But it also didnts work with stock or cyanogenmod 7.
I will send you some information I can see on my phone, if I won't forget it

Man, thats odd... I assume you aren't on the North American continent... Where did you pick your Gio up from?

You know... Its possible that the issue you have was fixed in a base band (modem) update... You could try flashing the phone to the latest OE firmware (Not necessarily the one that came with your carrier as branded firmware tends to take forever to get updated), and see if that works...
