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?
Sent from my Samsung Vibrant

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.

Major WiFi connection issue

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!

OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??

Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?

Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.

This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

WiFi connection drops, have to reboot - Virgin hotspot

My Nexus 7 had no problem with wifi connections since I bought in right after they were first released. Last week, I bought a Virgin Broadband Mobile Hotspot to use while doing some traveling. (In some areas, it works a lot better than I expected.) The problem is that fairly frequently, the connection drops and I can't reconnect. When reselecting the device (or any other network) in the list of available wifi networks, I get an error message that reads "failed to connect to network." My only recourse is to reboot. A fast reboot is good enough, but I've done plenty of those and complete reboots.
Then, I can reconnect. That new connection may last ten minutes or many hours. But at some point, the connection will drop and I'll have to reboot to get another one.
I figured this must be related to the Virgin hardware, but when I got home yesterday, I discovered that this happened again with my router. In the 5 months I've had the Nexus 7, I've never had a problem connecting to my home router. So I "forgot" my remembered wifi networks and reestablished them. There are only two, my home router and the Virgin device. Didn't help. Right now, I don't have the Virgin device turned on, so maybe this will temporarily solve the problem. I'm not sure, yet.
One thing that seemed to help was that when driving and using the Google Navigation app, this seemed to be less of an issue. It's even possible that we never dropped a connection while navigation was active. When nav is active, the device doesn't sleep. So there may be some relation there. But plenty of connections were dropped while nav was off and the device was awake. In fact, most drops occur when I'm stationary, i.e., not in a moving car or walking around.
Another piece of info — our other Nexus 7, which also came along on the trip, doesn't seem to have this problem, but it didn't get used that much, so it may be that it would be there, we just didn't have the opportunity to see it happen.
Anyone seen anything like this and/or have any ideas about what to do about it? Why would I need to reboot to renew a connection?

I had a similar issue,it would see connections not connect automaticly and when trying to manually connect it would disappear.I shut off the autoscan for networks off and it works much better.
Hope this helps

Thanks. I'll play with that and see what happens.

The nexus 7 that I purchased for my wife last week is experiencing the similar issue. I can see many network in range but any connect I try to connect will return a message "failed to connect to network".
I found some submitted issues on the Android project thread, but none of them offered any solution.

I'll try this at some other places to make sure the problem persists and will probably return it.

Wi-Fi auto connect issues

I am having problems with my Nexus 4 not automatically connecting to Wi-Fi. This is particularly annoying as I only live a few minutes from Uni so I spend the day cycling between my home network, uni network and 3G and set tasker to do things based on where I am. However, I look at my phone it tells me I have plenty of wifi signal yet it hasn't connected. This means I either have to switch the wi-fi off and on (which seems to take longer than it should to switch back on) or reboot the phone. After this it will connect fine. Is this a software issue? Or something that is just wrong with my phone?
Cheers

I too have wifi connection problems with my Nexus 4. I can get it to connect, but it won't reconnect. Not only does it not reconnect, it doesn't even detect that the network it was just configured to connect to is sitting right in front of it.
I've tried using Wifi Analyser, and it will show all the wifi signals in my area including those of my neighbours across the street, but it simply doesn't even show my wifi signal. Oddly in Settings, sometimes my wifi signal is not listed at all (reflecting Wifi Analyser's view), and sometimes it is listed but shown as 'Not in range'. It is very frustrating, and the only reason I have not yet RMA back to Google is I have a slight hope that the next update (4.2.2) will fix it.
Needless to say, I have a number of other devices at home (Lenovo and HP laptops, iOS tablets and phone, Windows RT tablet, Windows Phone, and Nexus 7) all of which connect to my home network OK. It is clearly a bug in the Nexus 4.

I had the same problem as you guys, i flashed Franco Kernal and it works a treat now.
Not forgetting the extra battery life the kernel provides.
I suggest trying it out.

Nexus 4 wifi issues

I got my nexus 4 off my brother as he recently got a new phone. I replaced the battery with a new one and all seemed to be going well.
Everything is stock, I have even tried flashing a few older stock builds LMY48M/T to try fix this. I currently have my sim card in an old phone while I am having issues with this nexus 4. I cannot remember if these issues also effected my phone sim network too. I cannot test this until the weekend. I could have damaged the antenna when replacing the battery.. but then when the wifi does eventually connect, it stays connected fine.
I am unsure if it is a problem with my Nexus 4, or my BT HH 4 router.
The issue with the wifi is my home connection says 'Saved' but it never connects instantly. However I could put my phone down and come back some time later and it would have managed to connect. As soon as I turn wifi off, and then on again it will just say 'Saved' and not connect. Once connected wifi works perfectly, excellent signal strength and link speed.
Things I have tried so far:
- 2.4ghz only, 5ghz only, and automatic
- Factory resets multiple times
- Forgetting the wifi network and re-adding password
- Going into recovery and wipe cache partition
- Restarting router
-
As for my BT HH 4, every other device in the house has no issue connecting, (shield k1 tablet, HTC desire S, TF101 tablet, laptops, chromecast all fine) it is just the Nexus 4. Maybe someone could reply who is also with BT and has a Home Hub 4. I cant see how it would be an issue with my router since everything else can connect fine. For this reason I would rather avoid changing settings.
Here are some things showing up when trying to connect my nexus 4 to the wifi from the Home Hub logs.
- Client associated - Client disassociated over and over
- IN: BLOCK [9] Packet invalid in connection (tcp reset attack is suspected:
- BLOCKED 3 more packets (because of Packet invalid in connection)
I have spent so much time searching around trying to fix this and got nowhere, so hopefully someone can help. Any posts I did manage to find were from years ago, I tried the suggestions anyway and still no luck.
