Not sure if this topic belongs here, but since people in xda are generally more knowledgeable, I'll try my luck here.
Here's the deal: I have a Galaxy Nexus. I setup wifi on my router (Linksys WRT54GL+Tomato firmware) and my Galaxy Nexus device is attached on eth1 interface on the router, which is right. However, every once in a while, the I see the wifi indicator on the notification bar goes grey and there goes my wifi connection. I check my router, and see that Nexus is somehow on br0. If I turn off wifi on the phone and turn on wifi again, my router's dhcp will assign my phone to eth1 again, but after a few minutes/hours, my phones goes on to br0 again.
This is very annoying, and I'm wondering if anyone has encountered this or has an idea what's going on?
Thanks,
Yes it happens to me as well. I have a D-link Dir-615 on custom firmware which is connected to the ISP modem. But i dont think my problem is with the router as the DHCP is turned off, the modem sets the address. If there is an unstable connection the modem tries to reconnect and the internet connection on the phone goes grey, but the connection on my pc works fine. I dont know the techical know-how so I just restart the modem and all is well.

I've upgraded my TyTn to WM6 using the new repackaged rom from Mrvanx, however I have a weird problem with the wifi.
It cannot see my router whereas before I upgraded there was always a strong signal.
I have set up the WPA encryption key etc. and also set the router up without encryption but it just shows unavailable in the list.
A neighbours network which is also WPA is found OK and it connects and asks for a key.
My laptop is connecting OK to the router so I assume all is OK with the router.
No mac filtering or anything like that installed in the router.
Noticed unlike old wm 5 the wifi Icon only stays active for about 20 secs even though in comms manager the WIFI icon shows it switched on?
Anyone got an idea what might be the problem. I do like the ROM but I do need my wifi on trips and I need to travel soon again so hoping I can fix this.

ROM 3.54,707.3 repackaged
Radio 1.03.03.10
WIfi Woes - part success - update
OK I found the answer but created another question ;-)
For security I turn off the SSID broadcast on my router. I turned it on and the TyTn immediately connected.
I always had a good connection on my original WM 5 ROM without SSID, but it appears the new one will not even see the network without SSID broadcasts.
Are there any other settings in the device to allow it to work without SSID because I am thinking that maybe some free WIFI accespoints have it turned off too?

I have a problem with my wifi, at work I connect to a Addon wireless router and most of the time it works ok.
But at the moment I'm having a problem where the phone finds the network, says remembered, secured with wpa/wpa2 psk, then it suddenly drops to not in range and my wifi status is 'disconnected'
It continously is doing this at the moment and just wont connect, the WPA key is correct for it as I have connected fine to the router before.

is the signal weak? i.e are you far from the wireless router?
Im sitting next to router and the signal is Excellent
Is there anything on the router that could be blocking my phone from connecting?
yes if someone has setup mac address filtering
Mac restrict mode = disabled
i have a router that every 3months or so i have to reboot!
i see it in the wifi available list but it won't connect
turn off and back on and hey presto.
not ideal i know but hey ho
could try a reboot on phone too
First of all, I have internet from Time Warner Cable and it came with a router/modem all in one. Now that was initially set up and that works 100% perfectly with my SGS2. Since I have a weak WiFi signal upstairs in a couple of rooms, I decided to hook up an extra router that is set up as an access point. The second router is connected via a cat5e lan to lan to my main router (home is wired with cat5e connections).
Now on the second router, I have disabled DHCP since the main router is responsible for that. On the second router, I set up a different SSID first to test it out. All wired and wireless connections worked great through my laptop/Xbox 360, PS3. My SGS2 connected fine as well and worked.
Now the issue is that the SGS2 "drops" the WiFi after some time. Sometimes it happens after 5 minutes, sometimes 30 minutes, etc. Even with the SGS2 right next to the router it happens. Meanwhile, my laptop stays connected the whole time.
I can't seem to figure out what the issue is now. I've reset the second router a couple times and set it up all over fresh but it doesn't fix the problem. Seems to be a problem with my brother's Sensation as well. Is there something with Android and access points or going through a second router that causes issues? Any other settings I'm overlooking? SGS2 connected to the main router stays connected until I turn WiFi off. But to the access point, it drops out after some time.
FYI: Second router (access point) is running DD-WRT firmware.
If you need any other info, just ask. I'll be home from work in a couple hours. I've been messing with this for the last 2 weeks but nothing seems to work. Please help! Thanks.
Hmm thats very odd. Im running a similar setup as you, except my main and 2nd router connect via 5ghtz N.
Have you tried statically your phone with an IP address then modifying your main router (that gives DHCP) to reflect that IP is permanently assigned?
edit: to hard set your phone...settings-->wireless and network-->wifi settings, then menu key and advanced. Just fill in the IP and gateway info, and obviously use something in your DHCP subnet. You'll have to look at your DHCP subnet, but you'll probably use 255.255.255.224 as your mask, and use your gateway (your main router IP) as your DNS.

Try giving your phone a static IP from your main router. Also make sure that you adjust your phones wifi settings under advanced settings so that your phone stays connected to wifi during sleep. Hope that helps.

Well my phone is getting the same IP address each time, whether I connect to the main router's SSID or the second router's SSID. But I will try this static IP. One problem is that I don't know how to find out my DHCP range. There's nothing in the main router's settings about the range. The second router has an option to set the IP address range for DHCP but the main router doesn't. See attached image.
I'll try to set the static IP around what the IP addresses of other devices on the network are since I don't know the exact range. Let me know if I'm doing this wrong. Not sure what you meant by 255.255.255.224 there.
The static IP didn't make a difference. Still keeps disconnecting/dropping after some time. Meanwhile, the connection with the main router stays connected. Don't know what else I can do. Seems that my HP Touchpad running CM9 stays connected to the second router without dropping. Don't know what's different about that from my phone.

Does anybody have some instructions on how to set up the second router as an access point? I'm pretty sure I set it up correctly but apparently there seem to be some issues. People who have a similar setup that can help would be great.
Main router from cable company with built in modem where internet connectivity comes from is downstairs. Connect cat5e from LAN of main router to LAN of second router upstairs. Second router set up as access point for better WiFi coverage upstairs.
2 options for second router: DD-WRT D-Link DIR-615 or D-Link DIR-625.
"Could" buy some other recommended router for this and try that if needed, but would definitely prefer to use what I have and get this to work.
This might be completely off but I had a similar issue with my SII when connecting to 802.1x networks at my University. I downloaded this app called wifi fixer and it resolved the wifi connection drop for about 90% of the time. Give it a shot, it might do wonders for ya.

First you need to find out if your router is supported. According to the DD-WRT database, the 615 is, the 625 is not. But there are several revisions of that router, so you need to find out what revision you have. It should be on your label.
Router database
Then you need to decide whether you want a repeater, an access point, or client bridged. You can read the differences in the DD-WRT wiki found HERE
Then you need to find the best build to flash to your router. I suggest reading the overview of the 615 found HERE. Read the ENTIRE thread. If you flash the wrong version to your router, you WILL brick it.
Then flash the appropriate firmware, set it up, and youre done. Youre going to have to do some reading.
edit: I would also suggest downloading wifi analyzer on your phone and do a site survey of available channels in your house. Most likely you WILL have interference from neighbors. Youre going to want to hard set your channel to the least congested channel, either 1, 6, or 11. Once you get DD-WRT set up on your 615 you can do a site survey within the router as well.
change the channel on your router to 6 not 11 i had that issue with our second router and actually my nook color. Depending on the router it should be under wireless settings.

The only reason to use one over the other is congestion. Thats it. And you want to use 1, 6, or 11 because the DIR615 has N capability, and you need a wifi primary channel to use N. Theres only 3 primary channels...1, 6, and 11.
edit: Heres a technical overview of N: CLICK ME!

I have actually done all that. The DIR-615 is an E1 version and I flashed the correct DD-WRT firmware on it. I followed a tutorial from the DD-WRT website to set it up as an access point as well. My laptop works perfectly with it. Just my phone keeps dropping the connection from it. My main router is on channel 11 and the second router is on channel 6. I also tried channel 1 but it didn't help.
I might just to try set it up as a second router on a different subnet than the first router and see if that helps. Going to try to follow this Youtube video and see how it goes.

Hhmm ok. Well your main router shouldn't have anything to do with it. When it drops does it re-aquire an IP and reconnect? Honestly if a reboot of the router doesn't fix it and your laptop doesn't have the same issue, its pointing to the phone.
Maybe a factory reset?

It reconnects when I unlock the phone. Sometimes I have to reset the Wifi on the phone. Have set the Wifi connection to never sleep. My brother's Sensation was doing this as well. I'll have to test it out on his phone and see. I'll probably reset my phone later today and see if that works.

For some reason, my Wifi connectivity on my GNexus has gotten really bad lately. I'm trying to connect to my home router (Netgear WNDR3400), and it gets stuck on a loop at obtaining IP address then avoided poor connection and it keeps reseting back and forth. It only manages to connect maybe 20 mins in the day and it looses the connection again.
Reseting the router only fixes the problem momentarily then the next day it can't connect again. The router is working perfectly fine in my house w/ the computer and laptops. iPhone and HTC Thunderbolt are also perfectly fine.
What can I do to fix this?

Have you tried assigning a static ip address to the phone?
Also what type of network? My phone does it on a 802.1 wireless b network with identity security (individual uname and password to connect) Which is what my university uses... annoying it was, but i found out that foxfi was causeing the issue. But im assuming your home network isnt like that.
How do I assign a static IP to the phone?
My router is 802.11n. And it has network security, secured by WPA/WPA2 to be exact.
App called WiFi static will let you set a static IP within a dhcp network. You probably can do it through your router as well. I would read up on static vs dhcp if you have never set up a static IP before. Also you'll want to see what all of the clients ips are so you don't create a duplicate.

Anyone having this issue on the Verizon stock ROM 4.2.2? I cannot connect to any wifi with DHCP. The only way I can connect is if I enter at static IP. I have tried about a half dozen access points with no luck. I have even done a complete phone wipe of data and tried reconnecting without logging into my google account to sync down my wifi settings. This pretty much prevents me from connecting to any public wifi hotspots unless I can guess their IP range. I have never had anything other than the stock ROM and OTA updates. Is there something somewhere I can clear or reset to fix this? It worked at one time long ago prior to jellybean I think.
At some points in your life, one of your Android devices connect to a wifi router, but can't connect to the internet. However, your computer, laptop or iPad will connect to that same wifi and use the internet just fine. I've looked everywhere on the internet for solutions, some of them are:
+ Turn off and on both modem and wifi router
+ Factory reset wifi router
+ Battery pull your phone, wait 30s and put it back
+ Reflash stock or custom ROM
+ Change DHCP IP setting to Static
+ Disable security (WEP, WPA) on wifi router
+ Check DNS server, gateway IP address for correctness
Fortunately, I stumbled upon this old thread last night -> http://forum.xda-developers.com/showthread.php?t=1371794
It helped fix the internet connection temporarily, turning off and on wifi on phone caused the issue to repeat.
In summary, he found out the correct MAC address for gateway was mismatched with the one on his phone. Even though the gateway IP address is correct (example: default gateway IP 192.168.1.1)
Upon further investigations, I found out my Wifi ROUTER has the same IP address with my MODEM (192.168.1.1) This IP conflict causes the phone to recognized the WIFI ROUTER's MAC address as the gateway's MAC address. This problem mostly occurs on Android phone, not computer (I'm no tech savvy so I have no idea why)
Simple fix: Go to wifi router setting page, change the IP address on wifi router to different number (other than default 192.168.1.1), and the problem should be fixed.
Please help spread the words to fellow Android lovers, I'm sure a lot of us have struggled with this problem :laugh:
I'm one guy who is desperately looking for a solution to this.
Unfortunately the solution you gave didn't work.
Hi
i have a problem with wifi. it remains connected but loses internet access randomly. i found this solution:
"In the wifi networks, select the network you want and select ‘Forget network’
Turn off the wifi
kill all the apps with your task manager
Turn on the wifi again
Connect to the network
Check the internet connectivity
If still the problem exist, switch off the phone and redo the above steps"
it solves the problem, but it happens again after some minutes. actually, i also installed an app named "wifi fixer" which does the above process automatically. when the program is active, it turns the wifi off and on every 2-3 minutes. and the phone has internet access when the program tuns the wifi on.
any idea?
Turn off wifi optimization on some android phones help.

2 years after the last reply I am having the same problem. My wife and kids all have internet access on their phones, tablets, desktop and laptops all from the same modem router yet I am unable to use the internet on my Galaxy S2 mobile phone even though my phone says connected to Wi-Fi Network Netgear 06.
The Mac address solution provided isn't applicable to my situation as my Mac address on my mobile is different to my modem router Mac address.
Any other solution?
