[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] Can't connect to wifi after Jelly Bean update

After updating to Jelly Bean, I cannot connect to my Wireless N router. However I can connect to my Wireless G router and I can connect via my Phone and FoxFi. I tried a paperclip reset on my infinity and a reset on the wireless N router.
Anyone else have this problem? Any idea how to resolve?

I ended up switching my wireless router from N only to N/G mixed mode and was able to connect... I verified I was still connecting via N and not G after making the change so I'm not sure yet what is going on yet. Everything worked fine until the JB update. I'll look at it more later when I have time.
Also, the router is a Buffalo WZR-HP-G300NH2 running the latest version of DD-WRT and it is set to WPA2 Personal Mixed and TKIP+AES, though I tired every combination and nothing worked (even disabling security completely) until I switched from N only to N/G Mixed mode.

Check the system date. Work for me.

Connecting to my work WIFI no longer works. We use EAP/PEAP with active directory integrated authentication. It tries to connect several times before giving up. Worked perfectly fine with ICS. I used to have the same problem with my old HP Touchpad (in WebOS).

Something definitely changed in JB that is causing issues for some with wireless network connectivity.
I experienced the same thing (worked fine with ICS). If your wireless is set for N only, try changing it to N and G mixed mode and see if that makes a difference. I did not have to change the authentication method, just N to N/G mixed mode to get it to work.
Though that resolved the issue for now, I sure would like to know what the real cause is (exactly what changed in JB?).

[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

[Q] Wifi Issues

Hello everyone. I have been having a wifi issue lately and I'm hoping someone here can help me out. I can connect to my home wifi and surf the internet, use Facebook and watch Youtube and use some other apps. Lately however, I am not able to use apps like Pandora, Slacker, 93.9 The Beat, POF, OkCupid and MeetMe. I'm sure there are others as well that I haven't tried yet since this issue has started. I can also connect to xfinity wifi (I'm not sure who's that is) and all of the apps work fine. I am on the stock ROM, S-Off and unlocked running Android 5.0.1 If any one could help, it would be appreciated. Thank you in advance.

Do you use a proxy at home? I know some apps don't work well with proxys...
Change anything recently on your home router?
Did you say everything works FINE on xfiniti wifi?
Xfiniti Wifi is a major cable operators wifi. You'd need to have access to their services to use their wifi.

Hello bigblueshock. I have not made any changes to my phone/router/modem. I have shut them all completely down and restarted them and that did not help. And all of the devices are up to date. Yes everything works fine when I connect to Xfinity wifi. I have ComCast/Xfinity cable and internet. I'm not sure if it's my Xfinity wifi I'm connecting to though. I have signed in on a prior occasion and I was connected, so maybe. But when I try to connect to my wifi (the one that I know is mine) that is when I have my issues. It was working fine up until recently. I am not using any proxy.

If you're connecting to a different WiFi (such as XFINITI) with no problem. I'd say there's a high chance somethings going on your end... whether it be router/modem related.
One way to test is to connect another android device to YOUR network, and see what happens... Possibly even an Apple device. Any friends or family have android devices?
If the router is one comcast provided.. maybe they pushed an update to it which messed up something.

I have an old Samsung Omnia II that is running on Windows 6.5. When I connect to my home wifi, Slacker Radio works fine and so does everything else on the phone. It connects directly to my Netgear wifi it does also show xfinity wifi as available as well. But it doesn't have the app like my much newer HTC One M8 has. My M8 does show my Netgear home wifi and that is the one I'm having issues with. It seems like it's my M8 that is having the troubles.

If you are at your own home you shouldn't be on the xfinity Wi-Fi side. You should be on your private network.

Try forgetting the connection and put the password and reconnect again. If that doesn't work, try if you can access internet on a different wifi connection than yours.

hi
you should know what kind of wifi technology on your router or your access point
because the moto g 2015 support only 802.11 b/g/n (2,4 GHz)

Is this happening with all APs?
When I got a new router at home, all devices except my G3 connected just fine. I had to change the encryption type on my router to get the G3 to work. I still have occasional issues with connecting to some APs (including public APs) but not being assigned an IP #.
