Wi-fi not working

After connecting to 3 different wireless connections and none of then working, I'm concluded that my wifi isn't working.
I go to settings and check wifi on, it finds the network, connects, but I lose my entire data connection for the duration wifi is turned on!
Is anyone else having this problem?

I'm having the same issues with the wifi. I downloaded wifi analyzer to make sure I was on a good channel. Set it to the best channel and my signal strength is 100%. I will be able to connect for a little bit but for some reason it goes in and out, connection unsuccessful, yada yada yada. I messed with all the troubleshooting solutions for my router (dgl-4300) but nothing works. If anyone can reply with a fix or point me in the right direction, that would be greatly appreciated.

Same Issues
Any help is greatly appreciated. Data working fine when on 3G but Wifi = no data. Connection is fine, IP is fine.
UPDATE: It's working again on my home WIFI. Will have to see if it's just an "at work" issue. Hopefully IT can assist.

Same problem with Verizon MiFi
I have had ZERO problems connecting to the Linksys access points we have setup at my home and my office, but recently my work provided me with a Verizon MiFi (as well as an iPad - don't hate ) and I've had MANY issues trying to get my Vibrant to consistently connect to the MiFi.
My iPad, Motorola Droid, and Laptop have no issues connecting to the MiFi.
On my Vibrant I'm running the 2.1 stock ROM with root & the latest ClockWork recovery.
It will "connect" to the MiFi (I use quotes because I can't really tell - it AT LEAST receives an IP). But I'm unable to send and receive data. I can't even browse to the MiFi's internal configuration page .
To FINALLY get it to connect consistently I have to do some kind of random combo toggling the wifi off and back on and then turning the MiFi off and back on and it will EVENTUALLY connect and stay connected with data flowing freely.
I've customized my configuration a little bit on the MiFi so I'm going to reset it back to factory and not change the config to see if it makes a difference - because at lunch I was able to connect to my boss' MiFi with no problem. I'm thinking it may either be the phone or the mifi...

I've connected to about 10 different wireless networks with NO issues, at all. The connectivity is actually much better than my G1/Nexus.
HOWEVER, last night at a bar I was connected to their wifi, strong signal, but I was not able to use Data. I was in a very poor reception area for T-Mobile... don't think that could be an issue, bit the other places I use wi-fi that is not the case.
I just chalked it up as a fluke and moved on. Not sure what was wrong.

I had this happen to me today. I just rebooted and it went away. Toggling wifi didn't help, but I only tried it once. The phone reboots so quick I figured I'd give it a try.

I have set the phone up manually with static ip. Seems like its a problem with the dhcp.

[Q] Wifi network problems

Hello everyone,
Recently I upgraded to the 3.1OS and after that I have been having some problems connecting to wifi networks.
I was at my parents house this weekend for fathers day and tried to connect to the network. Every time I connected it would bring the whole network down. On my tablet it would connect, then the signal would go "out of range" and when I looked at my phone I noticed it was back on 3g. After several attempts I determined it was my tablet that brought down the network.
I had been previously been able to connect using the 3.0 OS.
The network provider is Fios.
My tablet is unrooted
Any suggestions or ideas?

Hi, I am experiencing the same problem with 3.0.1 the wifi connection was working just fine. After I upgraded to 3.1 I am loosing signal, the strenght of the signal is much much lower as it used to be.
What I read in 3.1 they downgraded the wifi driver, maybe this is the reason.
T.

Is it possible to check any logs on your router (if it supports it) and see what exactly happened..

It is not about the router, my PC or my Desire get full strength signal. Even with EEE pad before update to 3.1 I had no wifi drops.
So form my point of view the driver is the issue.

There was some mention of people having issues with the non-NA supported channels like 13 and 14. Are you guys using these?

workaround
While not an answer to your specific problem, you could use the wifi on you phone and then tether your Transformer to it...that way you wouldnt be using up the 3G from your phone , still using the wifi technically..
Just an idea to get around your problem...

Was using channel 11, then I found out a lot of other routers are using 11 also.
So i switched to 9. Helped a little bit, but still not optimal.
Let`s see how it evolves. :-D

WiFi issue with router

I just got my S4 today and this will be my reintroduction to Android after using WP8 for some time. So far I can't give any positive feedback as I cannot get this device to connect with my wireless. I have a D-Link Extreme router and it works great with EVERY other device I have in the house. I use this for not only my mobile devices but also my PC's and Home Theater components. I cannot understand for the life of me as to why this new to the market would have such an issue. Has anyone else encountered this? Any help would be greatly appreciated.

I also had a D-Link router that the S4 simply would not stay connected to. It would say connected then work any where from 30 seconds to 2 minutes before the connection drops. This is due to a compatibility issue between D-Link routers and the S4. If you google this issue you will see a lot of posts regarding this. My S4 worked perfectly on AT&T's hotspot, wi-fi at Starbucks, and my work wi-fi so I knew it wasn't the device. I eventually had to replace my D-Link and now I can connect at home without any problems.

Wifi Connectivity Issues

My new galaxy s4 I9500 has been working fine until 2 days ago when the wifi started reconnecting every few seconds. I'm not sure what the problem is and I cannot find a solution for this. I have read the issues with the D-Link routers however I use a Netgear router and all devices except the galaxy s4 can connect fine without any issues. It started happening after my phone automatically updated to version: I9500UBUAMDK, but I am not sure if it has to do with software.
If anyone else is having the same problem or has a solution, please help me through this issue, thanks.

Anyone? It's the only problem I am currently facing with the phone and is a major problem for me as i use Wifi at home all the time. Please help me solve the issue and I'll be so happy!

i have also problem with my dlink 2640b and i found solution for me
you need to go to wierless settings and chosse CHANAL 13
and in option where you can chose wifi speed ( like b only, b and g mixed, only g ) chose G only

Thank you for the reply, and yes I have read that this problem is mostly on D-Link routers and that there are many fixes for that, however I am currently using a Netgear router which I haven't heard many people having problems on, so there are not so many fixes out there for that. Thank you for the reply though, I will continue to look for a solution.

Try changing the channel width to 20Mhz. After I did that the reconnecting issue was gone on my D-link router, but as you've read at 54g speeds. I can now stream video to my TV without it stopping. I am contemplating buying a new 802.11ac router to connect at 433Mbps as my D-link is too slow for my broadband now. I hope that helps.

Changing Wifi channel width from 40 MHz to 20 MHz solved wifi dropping and reconnecting problem for me also. I have Asus RT-N16 with latest updates. Also on my SGS4 has latest updates, stock android 4.4.2.
I used Wifi scanner, and there should not be any interference with my Wifi station. I have channel 1 and my neightbour has channel 7 Wifi. Wifi signal is also strong for my router. I was wondering how this can be possible, as any other device had not dropped connections @40 MHz widht, BUT a brand new Galaxy S4 GT-I9506 drops it withing minutes again and again?

Help weird Wi-Fi Problem

Hey guys
I have my Oppo Find 5 X909 and even though I am very happy with it there is one weird problem that I'm facing. When I connected my phone to Wi-Fi it connected to the router via the Wi-Fi repeater and it worked perfectly. But then one day the repeater was turned off and i connected directly to the router and even though it showed me that it connected succesfully I couldn't do anything that required internet. For instance i tried surfing the web with my Chrome app and it showed me a DNS problem which is weird because all the other devices in the house work just fine whether they're connected directly to the router or via the repeater. I tried restarting the router and making the phone forget the settings and readding them with no results.
I checked the official Oppo Find 5 forum and found that noone else was facing with such a problem and I have no idea where to look for the answers. I would really appreciate it if anyone could help me with the problem.
PS: my phone is running the latest Color ROM international build but I noticed the problem also on the newest official international ROM. Also the phone is unrooted

No such problem for me. I'm on latest Color ROM as well :-/

For some reason updating the router firmware fixed the problem. Thank you for the reply nonetheless

I'm having the same problem. Also only with one AP in my network. When the problem appears, no other device can access the internet through this AP. Sometimes even my wired PCs can't get access to the network.
My workaround is to try to always connect to my other AP.
I'm on CM 10.1 Nightlies. The AP is a Linksys WAP610N
