[Q] WiFi won't work, no matter what!

Hi,
I've just received my Samsung Focus AT&T Unlocked, everything's look good except WiFi won't work, no matter what I do. I've tried all suggestions posted online..
Did NoDo update
Tried WPA
Tried WPA2
Tried with No Security (Open Network)
Tried the channels 6, 9 and 11
Even reset the Router
Reset the Phone
I'd really appreciate any help, WiFi is a must for me!
Many thanks for your help!

You did NOT provide enough information so we can't help you.
Eg. Does your phone give an error connecting or does it not detect WiFi at all? Does your WiFi works elsewhere such as your office?

Oh sorry.
Phone detects all available networks, but can't join/use them. The error is:
"Connection Unsuccessful - Your phone couldn't reach the WiFi network xyz"
Yes, tried creating a network with my Macbook and joining, but that didn't work either.

Have you tried to connect using Wired connection (when your phone is connected to PC with Zune launched)? I just want to make sure that connecting to internet and getting and IP is not the problem.

Yes, that works. So I turned off 'Data Connection' from settings, connected to PC and opened Zune. I can access internet on the phone, even checked the IP, it seems to be using the PCs connection. Removed the USB cable, and there's no internet.
So yes, that works which confirms that there's physical fault in the phone, just a bug?

I had similar problem with my university wireless connection. After several access with Zune, the problem was fixed. And by the way, it may not be a hardware problem since your device detects the available network.
Perhaps you need to visit a phone shop.

Ah, thats a relief to know. And since windows is not officially available in my country, there are no shops.
I'm expecting one of the experts here to chime in and help, or someone who has experienced and resolced this issue before.
Thanks

Can you please tell me your router's mode, channel, fragmentation, treshold values. Maybe that'll help.

Anyone? WiFi not working is so annoying!
I'd really appreciate any help with this.

Try connecting to WiFi at your office or somewhere else.
I also have the Samsung Focus and it won't connect to a certain router no matter how I configuration the router.

[Q] Wifi doesn't work at home

Hi,
I have a problem with the wifi on my Samsung Galaxy S2 after I changed some settings on my home router. The wifi works anywhere else, just not at home.
What I changed was the router ip and wireless channel. Since then I have cleared all the wireless and browser settings in the phone and reverted back to the old settings on the router. Still doesn't work.
I've also tried having static IP. It doesn't work as well. It's only the internet. It connects to the router fine and I haven't had any problems with other gadgets and computers connecting.

Your tried turning on airplane mode for a few then reboot?
Your router doesn't have a sync button does it?

One thing you can do is delete the connection to your router on your phone, and connect again with new password from router. Do you have any other device beside your phone connecting to this router? If no, you need to test it. If yes and not connecting check the connection security, like wpa or wpa2. If all fail, reset router. This mean you will need to reconfigure your router. Check manual for more on your router.

Yes. View available wireless connections. Click your router. Then click "forget".
Then view again, click your router, and type the passphrase.

Just tried this and it didn't work.
My router is a cheap basic router that came from my internet provider. No such thing on it.

I've already reset anything wifi related on my phone. It hasn't worked.

Do you have something else that you can connect to wifi to see if the problem is your router?

Not in my home no. But like I said in the OP, the wifi on my phone works fine in other houses and hotspots. It's most definitely some kind of communication problem between my router and phone only but I'm not familiar enough with routers to know the problem and I haven't stumbled on anyone else on google having the same problem.
Two laptops, one Win7 and one OsX, are connected. Unfortunately I'm new in the area I live in and my girlfriend doesn't have a smartphone so I haven't been able to test if it's just my phone or just android or iPhones in general.
I can't think of a logical reason why it's like this

Maybe router is configured with wifi 802.11n and the galaxy only runs on b/g ?

If you're using WPA/WPA2 security, check that the
router is set to use AES encryption.
If you think you did your best. Its better to buy a new router then. )

maybe you could try unplugging your router?

I didn't change any of that. It's got a WEP encryption only as well.

[Q] O3D + WiFi doesn't connect to the internet?

This is a strange one, because it used to do it and nothing has changed.
The WiFi can obtain an IP from the router, it can connect to my PC via the router.... but it just cant connect to the internet via the router?
If I disconnect the WiFi and just use data, everything that has been waiting comes flying through!
Any ideas what is going wrong, the phone says it's connected, but I could swear my WiFi symbol used to go green, but it is just staying white.
Running 21E OS.
TIA.

Couldn't really understand (no offence) but if this happens to me I usually just restart my router and it would work again.

Do perhaps have a Netgear router ?
If yes reboot the router
Change wifi Channel from Auto to 6 or 7
if not try the above also try setting up a static ip
Do you have Droidwall installed?

Yeah I do have a Netgear wireless, I left everything off all night but no joy... I will try your channel change thing and see if that works. It's strange because it used to work and i haven't changed anything that I am aware of and the PC has no problem. But obviously nothing is being sent to the Cisco CM. Hmmm....
Thanks for the input guys. :good:

Sorry OptimusTM, it probably was a bit garbled in my original post.... basically the PC gets to the internet (probably like most folks here) by contacting the wireless, then the wireless contacts the cable modem then it goes to the internet.
However my O3D can contact the wireless, but the wireless doesn't seem to contact the cable modem for some reason, however it will contact the PC.
The phone says it's connected to the wireless. It has been given it's IP address.

Check your DNS server address.
Put manually 8.8.8.8 and tell us if it works.

Thanks again for all your help guys...
I ended up fixing it buy changing the IP address that the wireless router was giving it (set it to static) and also the default gateway to the same as my PC's and it worked straight away.
Still no idea why it had such a dizzy turn in the first place though!?!? :silly:

same problem please can you explain steps

Could you check advanced settings on WiFi and see if it says anything in IP Address box, also are you on stock ROM?
You could also log into the router and see if it displays the connection etc.

Is your mobile rooted?

And have you any MAC-Filters on your router where you have to add the MAC Address of the phone?

It's happen all android phones when;
-You far from WiFi
-Many people connected that WiFi, and it's reached max. limit
-Install & Delete VPN's...
-Maybe you or someone blocked your device from router.
Solution :
Unplug your router and plug again.If not work forget your password from Android Phone and re-connect it.

Actually the wifi I am using is provided by my hostel so here only the registered devices(they have registered the devices using the IP) are allowed to access the wifi, so I am using connectify to take that wifi as input to my laptop and from my laptop I am providing wifi so dat I can use it in my mobile. But with android devices I cant access it.
I m sitting rit next to my laptop, nd m da only user trying to connect to my wifi, i tried forgetting pass and re-connecting. Nothing worked.
I'll try 3rd option could you tell me how to Install & delete VPN's. Thank You

I was meaning its happen when you using, install, uninstall VPN.. U don't know VPN so u don't use it ;D
You said "I can't connect any android devices" that means your android devices don't have problem. It' s about router.

Can you connect that Wifi any android devices? If you can it's about with your phone if you can't it's about your router. Which device you using OpenVPN?
