I should note I am running CM6.1 RC2
So, I had the strangest thing happen this morning. I went to my in-laws for thanksgiving dinner and put my G2 on their wifi. It worked fine last night, but this morning after a few moments I am having very bizzare behavior over the wifi connection.
What seems to be happen is that the DNS lookup requests seem to fail when using the android apps. Now, for some reason, the wifi calling app connects, and I can place calls over wifi, but I can't use any other applications for data.
Here is where it gets weirder. If I ping an address, it works just fine, and then, since the dns resolution is cached, I can go to that domain in the browser, however any links that leave that domain do not work.
I have tried several things, setting a static ip address, using different DNS addresses (the router, and then google's dns addresses). Nothing seems to be working. I have also rebooted the router. Other device on the network are able to connect just fine.
The funny thing is that data works fine over the cellular network, of course there is only edge out here, and somewhat spotty coverage at that, but things seem to work just fine.
Any thoughts on what the issue might be?
Thanks!
Well, I ended up fixing it by doing a nandroid backup, restoring and clearing the dvalik cache. Weird.

My Wifi connected to my home router perfectly until I flashed the custom rom.
Now it wont work. the phone recognizes my network, then tries to connect but it pauses at the obtaining ip address bit and doesn't connect?
I tried to restart the router. It doesn't work.
I tried to reflash the rom or offical rom (KE7). It doesn't work.
I also tried to delete the file /data/misc/dhcp/dhcp_list, but there are no "dhcp_list" file inside 'dhcp'
Do anyone have another way to solve this problem?
Thanks
Could be a problem with the router, are other devices able to acquire IP addresses from it correctly?
Perhaps you should assign a static IP to see if that makes a difference.
I am on KE7 stock rom with root and had this problem too. It just started yesterday and got stuck at obtaining ip adress. So I switched WIFI off and flight mode on and after some seconds wifi on and flight mode off and it connected. I also noticed that now sometimes when it is in standby it disconnects from the wifi network (but wifi is still ON) and when I wake it up it connects to my network.
Me too, same problem.
If wifi is ruled on "sleep when screen turn off", it don't wake when screen turn on.
It stay on " searching for IP adress...".
For the moment, I'm forced to leave wifi on "never" and I use Juice defender for disabling wifi on screen off.
I really think it's a common pb with SGS 2. May be it will be fixed with 2.3.4.
Same problem. I 'fix' it by turning off wifi then turning it back on and it gets an IP address immediately.
same problem here with a dlink dir-615 router. from time to time the phone can't get an ip, and it only works if i reboot the router. didn't try with another router yet ( well, i connected to a few more but not frequent so i can see if there are problems), but i ordered a new one anyways since the dlink also crushes my battery too.
try posting the brand/model of the router you have problems with, maybe there's some specific ones that are troublesome.
d-link dir-615 here / ke7 stock - rooted
I also have a dlink router. But I get the same problem with a Belkin.
With my first SGS, no problem. I really think it's a specific issue on SGS2.
I'd read in some place that 2.3.4 will fix some wifi problem known for the moment on 2.3.3...
Let's see...
I'm seeing this with both my home router (Netgear WNDR3700) and my office router. Disabling & re-enabling WiFi on the SGS2 solves it -- fortunately, it's easily accessible on the notifications panel.
Same thing with Dlink dir 815.

Same thing here with Draytek 2820 router, all other devices (PC's Phones, PDA's etc) have no problem. SGS2 however needs WiFi turning off when waking from sleep to get it to obtain an IP address again. However my HD2 also running Gingerbread 2.3.3 works faultlessly.
KF2 seems, for me and some others, fix the problem...
hi
lucky me, i thought im the only 1 having problem with wifi
my problem, same as the others
the wifi try to connect (obtaining IP) and then disconnected
it will scan again, same thing will happened
try with all type of protocols, wifi b,g,n wep, wpa, no passwd
results still same
try to connect wifi at my office, results also the same
im on KF1 using dlink 615
hopefully someone can help us
tq
Just got my Galaxy S2 today. Cannot connect to wifi network on G or mixed mode, with or without security - just tries to obtain an IP address. Ridiculous.
Any help ? Quick search on Google doesn't bring up too much. There does seem to be an app called "FXR Wifi" but I don't expect to use that on a brand new phone.
Update: Upgraded my router's firmware (WRT54GS) and it works !
I have the same problem with my SGS 2. I can't connect to an AP - NETGEAR DG834G.
I found a partial solution to use my phone with my AP until I solve the problem. In the Wi-Fi settings menu enter Advanced mod and set the IP address, Gateway, Netmask, DNS1 manualy (by touching <Use static IP>). If you don't know what IPs you have to set for IP address, Gateway, etc. just connect with you laptop or desktop and use the settings from your computer. Just make sure you type a different IP address in your mobile (not the one from your computer - for example in you computer you'll find something like this: 192.168.0.3, you'll have to type in your mobile something like this: 192.168.0.10). The rest of the settings have to be identical.
Good luck!
To solve this "obtaining ip address problem". Set the following manually in the advanced configuration and save it.
1. ip address(your choice).
2. subnet mask(255.255.255.0).
3. default gateway(192.168.1.1).
4. dns servers(8.8.8.8,8.8.4.4)
Note: The above given values are the most commonly used, you change it if you want so.
After entering these values manually(and correctly), it will connect to the networ in 1 or 2 seconds.
like mine SG s2, wifi connects works perfectly at home and friends place,
but stucks at obtaining ipaddress for wifi, at the mall and college, ( where it needs first login page for authentication) ( or to agree user terms and regulation),
any idea, how to fix this issue.
Thanks
mine also does this where it doesn't get an ip. Reboot your router or just disable and re-enable the access point feature on the router and it should work without having to reboot it

but at university?college or mall, we dont have access to router.
any other idea to fix this
Thanks
Hey guys! Did you find a fix for this problem? I have the same thing happening right now. I tried at different places, home and country house with Zyxel P660HN and Cisco E4200 respectively. Stuck at obtaining IP address...

I have an AT&T galaxy s4 and I've been having trouble with the wireless. I can connect just fine to the netgear router at my apartment in Athens but at home I've been having trouble. At home we have AT&T uverse with an AT&T branded router. My phone will connect for a little while but eventually the small down arrow under the wireless symbol in the status bar starts blinking and the phone says it's connected but I don't have internet. Ive tried searching for a fix but it seems that the only routers people are having trouble with are dkink routers. The problem seems to trigger after I try to load a new site or refresh a page. Also, locking the phone triggers it as well. I've tried changing the security settings, forgetting the network and re-adding it, as well as turning the wireless network power saving option off but nothing works. I've rebooted the phone and the router but it still messes up. What's odd though is that my brothers galaxy s4 connects just fine (although I haven't been able to do extensive testing on his phone). Also, I was home last weekend and the weekend before and it worked just fine. I haven't rooted my phone or changed any settings that would have impacted the wifi since then. Anyone have any ideas?
I'm having very similar problems. When I connect to the wireless, the phone will work on it for about a minute and then stop getting to websites, etc. I have a Motorola SB 6121 cable modem with Vonage and a Dlink DIR-655 wireless modem. Inet provider is Comcast (only option here).
Anyone else having the same symptoms?
I've done the same troubleshooting steps: factory reset, power cycle, default settings, etc and the phone does the same thing.
EDIT: it's been working longer than usual now. I adjusted the Transmission Rate from the Wireless setup to 54 from Auto and the wireless has been stable much longer. See http://forum.xda-developers.com/showthread.php?t=2253471 for people sharing the same pain we have
Well this is weird, my new note is now disconnecting from my WiFi router after a short period of inactivity. This just started a couple days ago (just before this new 2nd firmware update). I'm not sure how long it takes to happen, but it's somewhere close to an hour. When I find my tablet disconnected, the notifications tell me that there are networks available in one notification and that my crudentials timed out in another. It will not automatically reconnect to my router either, so I have to go and reconnect to it manually each time...and it's a pain in the yang.
The odd thing is, it remembers the WiFi password, so it's not like it completely dumped the settings. So in theory, it should reconnect automatically since it still remembers the network and password.
It could just be my router, but my SIII and my laptop have never had this issue. I checked the settings to see if I was in power save mode or anything...but I'm not.
Any suggestions appreciated.
Well, I have tried restarting the tablet and the router...both to no avail.
This is getting frusterating now. I simply watched an epsiode of the Walking Dead and it killed my connection while doing that...WTF? It also did it later while my tablet was downloading a bunch of updates, so a few of those updates didn't download because the connection died after a while.
Why would it do this even when the tablet and the connection are active?
I am having the same issue, but it isn't my Note dropping the connection, it is my router rebooting.
Next time it happens, log into your router and check on the router uptime to see if it just reset.
What router do you have?
Mine is a D-Link DIR-655

I have the same router, but it's not doing what yours is doing (my uptime has been for over a week it says). But that does make me wonder if it is still an issue with the router...
I have been searching and some of the other samsung devices that had issues and some of them (that didn't require root) were fixed by setting the DHCP release time to 2 days (instead of holding it forever) and/or setting the ip to a static one on their phones. I plan on trying this next and letting you all know how it goes.
Yay! So the fix was to set a static IP on my tablet...that's it. My router was already set to release DHCP every 24 hours, so I didn't change any settings there. Before I did this, my connection was dropping about every 15 minutes. After setting the static IP, I let it sit for an hour and it's still holding strong.
Did you set a static IP directly on the tablet, or did you set a reserved IP on the router?

I set the static IP directly on the tablet and I have not had an issue since doing this.
Maybe you can restore your tablet to solve this problem.
does it happen on other wireless networks? what security are you using? wep/wpa?
try changing the security to see if that helps. odd that a static ip fixes it. its almost like it loses its ip configuration.
when your tablet looses network, are you actively using it, or was it in sleep mode?

The tablet would lose connection while actively using it...it was weird.
What's even weirder is that I have NOT set other WiFi connections to static IPs like I had to do with my D-Link router, yet the connections with those other routers have remained steady while in default DHCP modes. I have no idea why this would be the case (it doesn't make sense).
Like I said earlier, my router does not have very much in the way of special settings...just WPA 2, N-only mode, and a DHCP IP release after 24 hours of inactivity are the only options I enforced. Looking at my router logs, it definitely sees my tablet and updates the release time each time I use the tablet...but I don't see anything in the logs when the tablet suddenly disconnects from the router. So I have no idea if it's the router or the tablet. lol
I have not tried another security setting, but I don't want to lessen my security in this environment. Beseides, I know at least one othe router that I connect to is using WPA2 also.
I can live with this work-around as long as I don't have to force a static IP on every other router I connect to.
I have a different model dlink (dap2553) and I have the random disconnects also. I see wifi connected normally but no data flows. Eventually the connection drops and reestablishes fine for a while..before it all happens again.
Has the static ip solved this for everyone?
Tablet works fine on all other wifi aps and all other devices work fine on my ap
I also have a DLink router (DGL 4500), mind you, it's an utter piece of crap and I plan on replacing it with an Asus ac66u sooner or later. I also have this issue where it will show connected but no data will flow for a few seconds and then everything will be fine again. Static IP hasn't really solved much for me. I'm hoping that this indeed is a router issue so I can continue to use this in peace when I replace this DLink junk.
Static IP has not solved it for me. I have been using my travel router at home which does not reset.
change the channel on your router. the channel you're on may be saturated. i've got 3 routers with no problems:
1 belkin n300+ share - stock firmware
1 asus n56u - padavan firmware
1 asus ac66r - merlin
all steady.
Same problem. Just got it today and close to returning it. Factory reset and static IP didn't help.
Wasted 90 minutes trying different things. It's just bad hardware. I even installed Kies and let it re-image the whole thing to MK1 again (very very slowly). Just sitting at the intial setup where you pick the wifi you want to connect to i can watch it disconnect and reconnect over and over. Returning it in the morning.

I'm also getting annoyed with the wifi problem
I'm having this problem too and it's really starting to annoy me. It didn't happen when I first bought it but now I have to re - enable wifi at least 10 times a day. Wifi will turn itself off when I'm using the tablet or when the screen is off, when it happens seems to be somewhat random but it won't happen again for at least 10 minutes after I've re-enabled wifi. I have tried everything but a factory reset...
You guys either have bad wifi/router or have defective devices. Minehas been perfect.
hmmmm.....

I'm on my 4th Note 10.1 2014. All of them had this issue with a bunch of different routers/configurations.
with four acting up it's quite possible that your routers and configurations are the problem. the note may just be picky mofo and you need to tweak you wifi set up. if you don't feel like fidgeting with your network, just give up and get something that plays well with you set up. when you've got limited free time network tweaking is not oneof the fun things on my list, lol.
Hi-
Just installed LineageOS 17.1 on my Moto G7. When I enable Hotspot, my phone loses mobile data altogether, and I can't get it back until I reboot. I can still ping google DNS servers (8.8.8.8). When I try to use Private DNS to dns.google, I get "couldn't connect". So, it seems like the hotspot is interfering with the phone's ability to resolve hostnames somehow.
Mobile data works fine all other times, and I spent a couple hours on the phone with my carrier, and there's nothing wrong on their end (phone also reports it's still connected to the LTE network).
Any help would be appreciated.
Thanks!
Update:
Just did the August 16 update -- no change. Here's some more information:
When hotspot has killed internet access on mobile data:
I cannot ping any hostname (I cannot ping websitename);
I can get DNS resolution (I can resolve websitename to 172.217.9.196);
I can ping 172.217.9.196;
BUT, I can't get my browser to load a webpage with 172.217.9.196 (on my phone; it works on my computer).
I also appear to be connected to the local cell towers -- just can't get access to their internet.
None of this goes away when hotspot is turned back off, although if I turn wifi on, I can get access to internet again.
Weird stuff -- especially the DNS resolution that works but doesn't allow me to load a page.
Actually, it looks like I am NOT getting DNS resolution for sites other than google. Instead, I get something about a Canonical name ....
