I use an ASUS RT-N16 w/dd-wrt as my house router. I routinely have 4 devices on its wireless. This is the scenario (which has only just started happening recently):
my wife will connect her S5 to the WiFi at home
the S5 will report connected
every other device on the WiFi that is handy (haven't checked if it happens to my Roku) will be kicked off the WiFi
the S5 will be disconnected
I will have to manually reconnect my other devices, which report an "authentication issue"
The other devices in question are: my Optimus G, my Shield Tablet, our Acer Win8 laptop. Signal strength is not an issue. I have tried:
setting the S5's WiFi connection to our router to a static address
resetting the router to factory default
changed the channel on the router's WiFi
disabling the router's ACK timing
changed the router's WiFi mode to NG-Mixed
Has anyone ever encountered anything like this? Definitely one of the oddest issues I've ever had the "pleasure" of dealing with.

That is weird. I have all sorts of stuff connecting to my WiFi. I use a WD router that has worked extremely well. I would suspect something wrong with the router.
Sometimes routers go bad like any other computer part. Do you have another router to test with your setup?
Looked at some of the reviews of your model and some people had major problems. It has a two year warranty, perhaps get an RMA if still time left. Of course flash it back to stock.
I got the suggestion from elsewhere to create a guest network for her. DD-WRT's got the ability to create a fully isolated guest network, but I only had to create a new wireless vlan for her (bridged, even) & she's happily connected on her own little space (& I'm still happily connected on mine).
More of a workaround than a solution, but hey...
Nicely done.
Update!
My wife took her S5 w/her down to a girls' weekend getaway, & she had to turn off her WiFi while she was at the house because, you guessed it, she kept kicking every other client off of the network!
I'm happy at home w/her on a separate WLAN, but I really do wonder wtf's going on w/her phone...

Hello
My N1 can connect easily to all kind of wifi routers and modems without problem but not with my fitness club's one, they have a Linksys N160.
My N1 can detect the signal,enter the password but then it's stucked with the message ''getting ip...''
Where is the problem? is it a know hardware or software compatibility stuff?
Sometimes rebooting the wifi router helps. Also make sure that when the guy over at your fitness club reboots the router you don't have the wifi of the club saved. delete the saved wifi profile, reboot the wifi router and then try. Cheers.
Already tried it several times. I saw that OS4 of iphone/ipod have the same problem with router enabling Wireless-N, I will ask him to limit the router to B/G
I also had similar problem with Linksys WAG54G2 (at latest firmware). Then I changed to much cheaper adsl router, TP-LINK WD-W8960N and no more connection problem.

I had problems using my Nexus One on my SMC Barricade 802.11b/g/n router when 802.11n was enabled. Turned it off; problems were gone. I don't think that works well yet, though some people have said otherwise. Could be a router-specific issue.
Ok so it's a WAG160N to be specific.
He tried to use mixed B/G instead of mixed (which would imply N too) but it still stuck at getting ip...
I told him to throw this router in the garbage because anyway SE and HP mobiles can't connect too,but he said he would do it but his boss will never accept to pay a penny more
My parents had a router that did exactly the same, my phone got stuck on Obtaining IP, whilst the missus 5800 connected and broswed just fine.
It was a crappy old thing and they replaced it the other week, now I can connect and browse just fine.
I also use a linksys WAG160N.
bought a nexus one, could not for the life of me get an internet connection.
turns out dns on router is poofed, so i just set DNS from my isp manually on the nexus one together with a static ip and booya interent at full 802.11n speeds.
sometimes its the simple things.
This sounds similar to when I set my router to channel 13 or whatever the max was on it. My N1 would only sometimes get a connection, but would eventually drop it and stay off. Solved it by selecting a lower channel (WifiAnalyzer suggesten channel 1 as the best alternative to channel max) on the AP.
I can see that in CM6 nightly that I have since started using I can choose regulatory domain, and thereby open up channels previously blocked. If you can't change anything on the AP this might help you solve the problem on your end.
So suggestions if none of the posts above me provide a solution is to run WifiAnalyzer and see how the channel-graph looks.
I have an unrooted OG Droid running on stock Froyo (2.2.3). It's off-contract, but I have been using it by connecting to my wifi router (Netgear WNDR3700). Everything has been working fine until Friday when it stopped connecting to my wifi router. I tried reconnecting, but it cannot seem to find the router at all, even if I'm standing right next to it. My router does not appear on the list of available wi-fi networks when I look at Settings -> Wireless & networks -> Wi-fi settings. The strange thing is that it seems to pick up all of the other wi-fi networks from my neighbors without any problems; it just can't seem to find my wifi router.
All of my other Android devices (Nexus S, Evo 3D, Galaxy Tab, Logitech Revue) can find and connect to my router without any problems. It's just as though the router doesn't even exist from the perspective of the OG Droid. I haven't made any recent configuration changes on any of my devices or router. My other wi-fi devices (laptops, printer) don't have any issues finding and connecting to my router either.
I've tried rebooting, pulling the battery, etc. without any luck. Any ideas?
By chance did you unplug the router, my og DROID loses wifi sometimes and even though phone sees it won't connect but usually resetting router gets it to reconnect.

I haven't done that yet, because as far as I can tell, the router is working fine. The issue that I'm seeing differs from yours as the phone doesn't even see the router right now.
It's a bug in Android. Delete all the remembered wifi accounts on the phone and then you should be able to scan again. Once you scan, it should pick up the router again. Had this happen on a couple different android devices.

I gave this a try, but it didn't work. I can still see all of the other available wi-fi networks near me, but not my own router. Any other thoughts?

I've had this with my router whenever i reset it.
its because there are too many routers in your area on the same wifi channels . change the channel your router is on until its one with less or no routers on it and it will appear eventaullly.

I have same problem with you.
My LWW cannot find/detect the home wifi, but another device (laptop and samsung galaxy mini) can work well with the wifi network.
but my LWW can find another wifi network except my home network. but sometimes when I don't use the LWW for long time, and when I started to turn the wifi on, it can work well. but after I stopped the connection and start to use the wifi again, it cannot find the network again
I just had the same problem and fixed it.
Sometimes routers are configured to select and use the less crowded wireless channel. That can cause your wifi to eventually use channel 12 or 14. Like sleepyguy007 said, it is more likely to happen if there are too many wifis in the area and all channels are crowded.
As far as I know, Android devices are by default configured to scan only up to channel 11. So if the wifi is in 12 or 14, it will not be recognized.
Go to the wifi config screen, where all the networks are listed. There, with the menu button, go to "Advanced"->"Regulator domain" and set Android to scan all 14 channels, that should do the trick.
I hope that is the cause of the problem and you can fix it... Otherwise it could be a bug, and the solution may be harder
I'm so happy & surprised!!!
I had same problem and with your helps(phobophille & sleepyguy007) my problem solved:laugh: :fingers-crossed: :good:

my device is not showing any network on my device to connect wifi.
i have tried everything but the problem is same . not a single network is appearing in my device. all others are connected to the same. in my phone in advanced setting it is showing ipv4 address is unavailable. plz suggest something.
Got me a new router from my ISP, of course there were issues instantly! Having problems connecting to wifi. Called my ISP and they said there is a bug somewhere in the router or in android itself. The router is a ZYXEL P-2812HNU-F1. They said I needed to get a static ip adress to each device. I got my Galaxy S2 up and running in no time, however, my HP Touchpad is not being so friendly. It says I'm connected but I get the grey wifi icon. Tried to disconnect and reconnect but no result. Also tried to forget the wifi and so on but no result. Also changed to b/g since it handles /n aswell. I've changed the router channel. In addition, my TP have begun to reboot randomly often in very fast cycles. I've flashed the Supreme mods a few days ago and everything worked flawlessly with my old router. Could the Supreme mod interfere with this maybe? Anyone please, this is so frustrating!

The wifi icon color is blue when you're connected to the Google servers. I remember reading something similar to your situation, I'll post a link if I find it. Meanwhile, you've probably tried this, but in case you haven't, try turning the router off for a while, then turn it back on again. You might want to go to a later build, they're quite stable. I'm one of the lucky ones, only had any wifi issues once, and turning the router off then back on solved it for me.
Good luck.
Edit : Try deleting the Supreme mods, they might be the problem.
As you said, I've tried to switch off the router and put it back on but I tried it once again but no result. I've also removed the supreme mods but there is no difference. I still get the grey wifi icon. Maybe should try a newer build, so tiredsome though but maybe the only solution. Will call my ISP for a factory reset on the system aswell.
Edit: Managed to come up with a solution. My ISP wasn't of any help so I had to do something on my own. So, I changed the security to wpa instead of wpa2 and noticed that my tablet got connection! The thing is, I want to use the /n standard and wpa does not support that. So (again), I had to enable a second wireless network and luckily my router supports four. One network with wpa2 (laptop) and one with wpa (tablet). Not a pretty solution but it works!

I did read somewhere that giving the TouchPad a static IP address helped with a lot of WiFi problems, maybe its something you could try. I personally haven't had any WiFi problems so I have never needed to test it.

Made a little update on my previous post. The solution was that I needed to change the security on my network (wpa2 to wpa). But as you mentioned, I needed to set it to a static IP adress aswell. Up and running now, as I type at least
try running an atheros update. i also prefer wifi analyzer for connecting to wireless networks rather than the android wireless settings. It shows you detail and information that android settings do not. Lets you configure channel options for B/G/N and A. plus more. its avail in google play.
Hi folks !
Recently I started to experience some troubles using my WiFis connections. The problem is simple, the connection drops, the WiFi network disappears from all the devices, and a few seconds later it comes back.
At first I thought it was a problem with the router of my work. But then I started to experience the same things at home. Then I decided to test the WiFi without connecting my Razr i to it and it worked like a charm. Now, as soon as I connect my Razr i to a WiFi, it crashes a few seconds/minutes later and keep doing it until I disconnect my phone from the WiFi.
Did someone experience the same thing ? Have you any idea for solving the problem ?
Thanks anyway.
PS : I only use 5Ghz WiFis. I'll try with 2.4 soon but the 5Ghz compatibility was one of the reasons why I bought this phone...
We have also issues with our WLAN at home, which is sometimes (but not always) very unstable in connection with a Samsung 5 Laptop (regular reboots shortly after activating the laptop Wifi).
I did not experience this problem yet with my Razr i, but I will keep it in mind over the next days (we have a complex setup with several computers, phones and Android entities based around a Fritzbox 7390, so error identification and validation takes very long and is not finished yet).
BTW - if you look for help here, please specify your WLAN router in detail as well as your provider and general IT-setup.

Well ! Thanks for the reply.
My router that provides the two WiFis is a Cisco Linksys WRT61N.
My setup is kinda complex but works well. Got another router provided by my ISP, which is the DHCP server. This router is connected to a port of the WRT61N switch. Not to the internet port. Every connection that enters in the ISP router goes to the Linksys, and then is NATed by it. I don't think those informations are very relevant but anyway here they are. That's a complex setup but it works well (needed to do that because I have cable connection, and the cable modem/router have very limited configuration).
The devices that use my two WiFi are :
2.4Ghz : My Razr i right now.
5Ghz : Two iPads, and the HTC 8X of my girlfriend.
I made some other tests, one the Razr i there is an option for switching on or off a kind of network frequency. So instead of both enabled, I enabled only the 2.4Ghz WiFi frequency and connected my phone to my 2.4Ghz WiFi. No problems detected. Stable connection. Right now I'm at work, and everything works well in 2.4Ghz. So there is clearly a problem with the 5Ghz frequency on my Razr i.
Anyway, during those tests, I discovered something very interesting. My battery life had a huge improvement with the desactivation of the 5Ghz WiFi frequency.
Thanks for the details - especially on the 2.4/5 GHz topic.
I am also at work right now, but will check it at home and keep you posted.
WPA2
I had the same problem, I think it was triggered everytime the phone went to "sleep". It was changing the security encryption that fixed it for me. I can't remember what i had on the router as default, and I'm not at home right now to check what I'm running, but I believe it's WPA2. After the change, I had no trouble whatsoever. Hope this helps, good luck!
EDIT: nevermind what i said, i just logged into my router and remembered it wasnt the encryption type settings, but rather the wifi standard used, it used to be 802.11 b+n+g, and now i got it sitting at 802.11 b+g, which equals to 2.4 GHz. Meaning the razr has apparently a problem with the 5 GHz spectrum..
I too have a RAZRi which is connected by wi-fi at home to a Fritz!Box 7390. I noticed that when the RAZRi went into sleep mode with wi-fi connected (keep wi-fi on setting) it would have lost any internet connection on waking, requiring a disconnection/reconnection to reset. More annoyingly there was also a loss of connection (IP address) at laptops also connected to the router by w-fi on both 2.4GHz and 5GHz connections, which needed a reboot of either the PC or the router to re-establish a connection. The router GUI would show them all as remaining connected.
By using the manual setting on the router to restrict 2.4GHz connections to b+g (not b+g+n), it looks so far as though both problems are avoided, and the RAZRi can be set to use either the available 2.4GHz or 5GHz (a+n) connection on the Fritz! successfully without problems. EDIT big problem is though that disabling "n" on 2.4GHz seems to cause wi-fi throughputs to crash by more than 50% on both frequencies (which for me negates the benefit of having VDSL) - they recover if I re-enable, but then the lockups start if the phone is connected. A hobsons choice.
Thanks guys.
Seen the issue posted everywhere with the basic T/s off/on network and factory reset. Usually fixes for a bit but comes back.
Hard to report the error as when I open Samsung members to run diagnostic I can't load the splash screen unless I turn wifi off https://9apps.ooo/.
My unconfirmed suspicion is it doesn't like HTTP3 so apps that are modern enough to use it just hang until I go onto mobile data.
I actually work for my ISP so I have confirmed no local network or ISP related issue but no wifi adaptor card in PC to try a packet capture to actually confirm what's going on.
If you issues are like mine were (randomly wifi would report no internet connection while other devices on the network connected fine) it ended up being my router. Switched to a newer one and the issues went away. An IT friend of mine said it was likely because the router was older and while it said they were compatible they were still using different versions of one of the connection standards. If you have a different router, give that a try. Side note, the router is a TMobile internet gateway and is obscenely fast. The new wifi 6 is awesome.
