[Q] Wifi signal?
Does anyone get a weak wifi signal with their Nexus S? Whenever I connect to my at home wifi I never get full bars and something I'll just randomly lose signal. Also it seems to go pretty slow. I used to have the Mytouch4G and it work flawlessly with the wifi. Anyone else having this problem?

OMG yesss I do.
Just about a room away I loose signal, almost completely. = 0

IDK, but I see more flaws every day that passes

Mine's been working fine over Wi-Fi. I'm pretty glad it does too, because my only data option with it is Wi-Fi..

Wifi has been working great for me. It reconnects automatically and doesn't drop. The signal seems on par with my nexus one.

Speed wise, is it on par with the 3G network?

[Q] Wifi does not work anymore after rooting :(
So, I unlocked my Android 2.3.1 and rooted it ... But if I click on wifi so I could connect to my modem it says Error and wont even search or anything. I tried reseting too but still no luck .. What is the problem and how to fix this ??

That's odd, I didn't have any issues with wifi as I connected to Android Market to downloaded ROM Manager during my rooting process earlier. Have you tried flashing a custom ROM on your device to see if it'll fix it?

No I didnt, would that work? .. A friend told me to install a new "kernel" but I dont want to overwhelm my android with custom made kernels .

your problem is you used one of the quick methods of rooting your phone, which used a kernel that wasn't from the exact rom you have.
if your on stock 2.3.1, you will need the stock 2.3.1 boot.img, and then you'll need to root it manually the long way via adb command line. search the nexus s development section for how-to's. they are all there.

i too had this problem, had to install MoDaCo ROM to fix it, but i dont regret rooting, i now have custom rom and over clocked cpu on the nexus s
you have two options, either to flash NANDROID backup to un-root and return to stock or install a custom ROM, i choose MoDaCo bcoz of its UI, it looks and feels just like the stock one.

Yes, that's the point of MoDaCo roms, to make minimal changes to the look and feel of the phone, but to improve performance with his custom optimizations.

[Q] Nexus S wifi issue. Unable to access wifi from my nexus s.
Hi Guys,
I was able to connect to my wifi network for a day. I am using windows 7 machine as hotspot with connectify. From second day I am unable to connect to any wifi network. I did factory reset my nexus s but no results . Can some one help me how to solve this issue?
Observations:
*when i use static ip, It shows connected but the bars are in white instead of green color and i am unable to browse.
*When i use dynamic ip I am unable to connect to wifi. It shows obtaining Ip and never connects.
*In connectify when I was able to connect to wifi the device is shown with an android device name. but now the device is shown as unknown.
Sorry for my bad english, I m not a native english speaker.

[Q] Nexus S Wifi Settings - force close
Hi all,
Just got a new Nexus S - all was well at home. Took it to work today and noticed something very odd. It was fine until entering the wifi settings menu - at which point it dramatically slowed down. I got two 'not responding,close or wait' messages before being able to join the network.... all other settings are fine - just the wifi area.
Weird - wondering what could cause this... too many wifi networks broadcasting (am in middle of London)...?
Anyone seen anything similar?

Too many WiFi around you shouldn't cause that.
Try rebooting and setting again if you haven't already.

Hmmm - rebooted and still have the same issue. At home, or even a block away from the office it all works fine. But in the office itself, although it connects and uses the wifi fine, the settings page is VERY slow to load and gives me the wait/force close message.
Out of interest - I also have 'wifi analyser' from the marketplace. This too is very slow and unresponsive when in the office.
So - it is definately something to do with the wifi here.... but have not got a clue what. Before I join the wifi, or when I am physically somewhere else it all works fine.
Wifi is WPA-TKIP, the key is a very long jumble of letters but surely that is not an issue.
Strange eh!!!

[Q] Possible WiFi problem?
Hi there, just bought a Nexus S, also used to have Nexus One.
The thing is for some wireless networks even though I enter the password correctly, it says connected and still there is no connection at all. (I mean browser tries to connect but at the end it says page could not be found) I even tried with an ad-hoc network that I created with my laptop but still the problem exists.
At home I'm able to my network without a problem. The type of network I'm trying to connect is: WPA2 Personal with AES. Is there any known issue about AES at Android system? Afaik there is no way to change the encryption used right?

this might actually not be a nexus S issue.
some modems/switches/routers are configured to block certain devices/applications/package's
we have a modem and router with both wifi.
but my psp/nDS cant connect to the modem,but can connect with the router

i have a similar problem. My Nexus S connects to my router only within a few hours after a router reset. Then it stucks at "obtaining ip" and never connected before I do another router reset.
My home wifi is WPA2 type, and for WEP type wifi my NS never got connected.

[Q] 802.1x EAP (PEAP) - Wifi connectivity problems

hey folks, i got massive wifi connectivity problems, but only with a special wifi at college.
it's a 802.1x wifi, with EAP (PEAP) and MSCHAPV2.
i configured it correctly (for sure), as i can connect to it manually. but it is not stable, though i got full signal strength. it keeps on dropping after a few minutes with the phone sleeping... when i turn it back on i have to reconnect manually, sometimes i have to deactivate/activate wifi, sometimes it is enough just to connect manually again.
i tried some roms and kernels already, with no effect (arhd 3.1.1, insertcoin from 2.2.1 up to 2.4.3-2 and 2.2.5SSE; kernels were faux 0.1.0 - 0.1.4, bricked 0.2 - 0.4). also stock rom doesn't fix the problem.
i think it's htc based.. somebody else got this problem? is there a workaround availible?

Nobody? Bump...
Sent from my HTC Sensation Z710e using XDA App

Hi,
I think it's HTC based too... I've seen this problem with my HD2 and now the Sensation (definitely hoped it was only an HD2 problem but here I am again, looking for a solution).
The symptoms are that you see the wifi connected with, say, full signal, but when you try to open Google Talk or the browser or anything, no data can be reached. This happens particularly when you switch from one AP to another (e.g. walk across compass) or if you leave the network area and then come back.
Do we have similar ones? My school has a registered-MAC network that also doesn't work well with the phone, so I believe it's more to do with how the network infrastructure is set up. However, my friends with non-HTC devices do not report such problems. It's also possible that my similar program installs on both phones do some conflicting with networking, but it's doubtful...
Does anyone have similar experiences?
Edit: It'd almost be preferable for my phone to just drop wifi entirely when the connection fails, since it believes it otherwise has a connection, but everything time-out-s. Having it switch to 3g when it stops working would be preferable to having no networking and no push email or messages...

You can try going into wifi advanced settings and setting the wifi sleep policy to "never", and see if it that fixes it. My high school uses the same 802.1x EAP/MSCHAPv2 security and I also have issues with it, but I think there it's because of such a dense network of access points (there's an access point in EVERY room) it's more interference problems and the phone jumping from AP to AP rather than issues with the phone itself. Download wifi analyzer from the market and check the different access points and if their channels are overlapping and compare their signal levels. If the signal levels are close, the phone might be jumping from AP to AP like mine does.

Dropping WiFi
May not apply to you. But in my case, when I have the WiFi Calling App turned on, I will lose connection to my Home WiFi which is password protected. And when I try to re-connect I have to enter the password again. With out WiFi Calling enabled, I stay connected till I disconnect. Not sure if this would act the same with a different router or without password protection, and since I have a good signal at my house I haven't checked all possibilities.

Thanks for your reply!
I've never set wifi sleep policy to anything but "never," and I've toggled between "Best Wifi Performance" and the alternative of having that disabled.
I've hit in *#*#4636*#*# and looked at the wifi state. It continues to say it's connected with COMPLETED Supplicant State and a valid IP address. Ping test, of course, fails, when this happens.
This happens for me both with mac-registered (insecure) networks and 802.1x networks on campus, but I've found that wifi is rock stable on most home networks, for example...

It might just have to do with the access point interference. I know that my phone has trouble handling the access point switching, regardless of the phone or ROM. My old 3g slide did the same thing. If it only happens on 802.1x networks and it happens on every ROM (which I'm 90% sure it does) then it's probably not something you can change.

I understand that, but the part that gets me is that my roommate's Galaxy S has no such problems.
I've tried many different ROMs when I was on the HD2; I'm hoping I won't have to go through that again!

Oh, then maybe it is a phone issue. I always thought it was just android but I've always used HTC devices. I don't know exactly how 802.1x encryption works, but if it's on a hardware level like some encryption algorithms then it could be HTC specific.

It's definitely a HTC problem. Friend of mine doesn't have such problems as well, he has a SGS2. Everything is configured like it should be, WiFi drop on "never", as already witten in the first post.

Same problem. Connecting at college over EAP with PAP and TTLS. Won't reconnect without upening credential dialong and inputting password

i'm trying to get it fixed by posting some logs to show-p1984, kernel developer of bricked. he is also german, which makes it easier to talk about this kind of 'special' problem for me i will keep this thread updated if there is any solution availible.

That sounds great! Let me know if I can contribute as well (logs? something else?).
I was worried it has something to do with the custom kernels we're all using (i.e. power modes for the wifi and such, but I did edit an HD2 kernel to turn that off and it didn't work). Since show-p1984 is thinking about this now, I'm sure he knows what's up with everything kernel=related to wifi...
When I have time, I'll definitely try a stock ROM again to see how it goes, since there aren't as many complaints about this problem as I'd expect there to be (i.e. ... maybe only us custom ROM users may have this problem with certain wifi infrastructures)...

Hello!
Not sure if anybody's still interested in this problem, but I tried the EU stock rom and it didn't change matters.
Basically, moving around campus makes my phone drop the internet connection on wifi, but not the wifi connection itself. Again, this doesn't happen on Samsung phones, and cycling the wifi fixes this problem.
See attachments for what shows up; it looks like after cycling I get a new lease and it works again.

So do people think the latest bricked kernel fixes this issue?

Unfortunately it doesn't. But at least we have a kernel dev who is aware of this problem. I got no doubt that it'll be fixed one day ;-)

Have you had any luck getting connected? I also have the same problem on my school network.

Still no change... As it's a driver of the wifi module, maybe it'll never be fixed at all. Anyways I hope, that maybe with the ICS update a change will come. Also there is show, who is aware of it.

EAP connectivity issues (ARHD 6.2.1)
I am suffering from this problem also when running ARHD 6.2.1 XE ROM for the senation which is ICS based. Has there been any progress on this?

Unfortunately - no
I'm running InsertCoin 4.4.6 based on 3.25.xxx leak with ICS. It's still not working... Maybe with the final release from HTC.

[Q] [Help Required] Wifi Problem, but nothing seems to fix this.

For a month or so I've been having wifi problems with my phone.
It's one you often see discussed:
either A)
wifi scans, picks up presence of network [with excellent signal strength] then, on click, doesn't try to connect just changes to say out of range.
Alternatively B), it simply doesn't see the network at all despite me being 2 feet from the router.
This happens with my home router [we have two, neither work] and with what seems like every other router too.
I am currently running the 6.1.1 version of ARHD [with android 4.0.3].
I can provide any information that might help, I'm not at all bad with this sort of stuff normally, although not collosally experienced with android.
Thank you for your time.
PS. Steps already tried to fix problem:
Power cycling router, installing different ROMs,scripted wifi fix for 6.1.1, changing wifi channels, switching router to just b and/or g, wifi fixer app, removing authentication, using different router, changed radio, changed kernel, and possibly more.
Please any advice would be fantastic, I struggle to use this phone without wifi.

Try the wifi with your sim in a differnet phone - when that works choose a different rom make sure you go back to a stock RUU before the new rom

I've never been able to connect to a wifi network on my sensation. I've tried it with the stock 2.3.4 ROM, and with all of the ARHD ROMS.
I can see wifi networks, and enter the network password, but it'll never connect.
So I'd be interested in any solution for this problem also.

Have you tried on different routers? I can only assume the routers channel is set to one that the device won't work on? Have you changed your router settings before
Sorry my bad only read half,

OK what is your devices mac address showing up as? Maybe it's the same as another device on your network?
Have you done a full wipe of your device?
Does your bluetooth work? (same antenna as wifi)
Has it ever worked?
Have you tried disabling all your routers security?

[Q] Wi-Fi connectivity issues

Hey guys,
I'm having some issues with my Wi-Fi connectivity on my N5 and it's freaking me out! :crying:
When I'm trying to connect to my home network, the Wi-Fi icon is getting orange after some random time.
Some times it gets back to white, some times it's not.
I know its a known issue but nothing seems to fix it.
I tried everything - reboot my phone, reboot my router, reboot into safe mode, forget the network and connect again, toggle into airplane mode and back, change Wi-Fi settings to connect only to 2.4 GHz, avoid poor connections, update my router firmware.
NOTHING worked!
The only thing I haven't tried yet is factory reset but I read some people saying it didn't help them either.
Only turning Wi-Fi off and than on again makes it "white" again for some other random time.
I'm running stock everything on a rooted device with Android 4.4.4 build KTU84P.
My Wi-Fi is working great with other devices in the network including a Nexus 7 2012 and some laptops.
And it seems that my Nexus 5 is connecting fine to other Wi-Fi networks.
It worked fine in the past and I think it all went wrong when I replaced my Modem.
Any ideas what else can I try?
Do you think maybe the Lollipop update will fix this annoying issue?
Thanks!

Forgot to mention (I guess it is obvious) - I can't connect to any website or run any network connected app when I'm "orange" (I know it means I'm not connected to google services).

Tried also to change my Wi-Fi channel. still not working.
Doesn't anyone have an idea what is wrong here?
This is really frustrating ... :crying:

Well, I'm kind of talking to myself here, but in case someone else is facing this annoying issue, here is what fixed it for me eventually:
Configure a static IP to my phone in the router configurations ! :victory:
Before that, I also tried to disable Wi-Fi optimization in the phone Wi-Fi settings, buy it didn't seem to help.

WiFi issues after Marshmallow update

Hey guys,
Having an issue with WiFi since the Marshmallow update. We have an open WiFi network at work that you need to sign in to the firewall to access internet. Previously it worked fine, but after the Marshmallow update, my phone constantly drops the WiFi network. It always happens when I lock the phone or otherwise let the screen turn off for more than about a minute, but it also happens even when I'm using my phone, if I'm on for more than about 5 minutes on average it drops the network. When I go to reconnect, it lists under the SSID "Internet not available" but I just tap the network and tap connect and it connects anyway, doesn't even make me sign into the firewall again. I'd really appreciate some help with this, if I can't get this fixed I'll be doing away with Android for good. I don't use my phone for much other than Facebook and games, so I'm not at all opposed to using a custom ROM if that would help. Just haven't installed one since CM7 on my HTC Evo Shift, so I duno which would be best for my situation. Thanks in advance for any input!

Bump. Hopefully someone has a solution...

One more bump before I give up...

Hi, I'm on stock firm, and after the last upgrade, I cannot connect to my work's wifi network. It's a EAP-MSCHAP2 connection. At home, wifi works flawlessly....

try talking to your system administrator at work. The upgrade may cause a comparability issue that maybe fixed by a simple tweak at work.
