[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...

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?

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] Captivate - WIFI sometimes auto connects, sometimes not

The problem I am having is that my the wifi sometimes connects automatically but sometimes it doesn't. If I notice it hasn't connected, I just go to settings -> Wireless and network, and then as soon as I select wifi settings, it connects to the wifi.
This happens both when I go to work and when I go home. These are saved wifi networks. I am always within about 20 feet of the wireless routers so I know it isn't a signal problem. At home there is only the one wifi network so it isn't interference from competing wifi networks.
Has anyone run into this? The odd thing is that it sometimes works so it doesn't seem to be a setting issue.
This is a Rogers phone that I unlocked and played with various replacement ROMs, but then loaded the rogers 2.3 ROM using instructions from this site.

[Q] WiFi connection issue after updating p3100 to ICS 4.0.4 ?

I have trouble connecting to WiFi networks (once in 5 iteration) after updating p3100 to ICS 4.0.4. If the problem surfaces, I have to turnoff and turn-on the WiFi couple of times to make it work again.
I have seen this issue consistently with multiple WiFi network with different configurations (WPA, 802.1x, without security).
I am considering downgrading to ICS 4.0.3. Or could this be a hardware issue in my tablet ?
Suggestions please.

My tab 2 (P3100 on 4.0.4 via OTA) have similar behavior sometimes it will connect but other times it just shows connecting until i turn it off and on several times.
But one thing I notice this thing happens when I try to connect to my home router which use 'n' networks while using my mobile 3g router (b/g) it connects easily (that I've tried currently). Does your wifi networks use 802.11n or b/g?

I have the same issue with 4.0.3.I hope it is not hardware related.

My home router supports 'n'. But i have configured it to work only on b&g.
In my case I see this issue with b&g setup as well.

I have been chatting with 3 Samsung agents and none of them are able to fix my tabs,they just want me to fill out the service request form,give me a break,I received the tablets today. What a joke.

I have an interesting find.
Instead of just turning WiFi off and on, if you do 'forget SSID->WiFi off-WiFi on->Connect" there is no connection issue at all and it connects every time without any issue. Which makes me believe that it is a software issue.
I have got another update last week (P3100DDBLF3) and I am disappointed to see the issue exists yet.

Removing the SIM card and doing a factory reset will wipe out this issue.
But then again put your SIM card back and try to connect disconnect your WiFi, There you got the problem again
This looks more like WiFi, GSM-Nework co-existence issue. Samsung .......:cyclops:

I reckon that recently samsung re-deploy 4.0.4 update for gt-p3100 and its variant. Does it still have this issue?

i dont think it is because of the hardware. ive used to had this problem. since ive updated my device to 4.1.1 jelly bean. it works fine. connected to the wifi almost immediately after i push the button

Random WiFi slow down

I'm noticing strange WiFi issues, in that my data speeds keep slowing down to a standstill for no reason.
In fact, when I first booted the device, and started to install my apps, I wondered why there were downloading so slowly, so I installed "SpeedTest" and sure enough my data speeds were like 1.5mbps. To test that my network hadn't just suddenly gone crazy, I ran the test from my laptop and that confirmed normal speeds.
To remedy this, I changed my advanced wifi settings to just use the 2.4 ghz signal, then changed my router settings (a BT Home Hub 3) from smart wireless (auto changes channel to the "best" channel to just remain on that already pre determined best channel.
I then immediately saw an improvement, as it was downloading now at about 27mbps... and so I thought I'd cracked it.
Apparently not.... It regularly goes back to downloading really slowly, and sometimes, messing with all those settings again doesn't do anything to improve the speeds.
Anyone else experiencing this, or has any insights as to what is going on? could it be a wifi driver issue, which may be rectified in later updates or baseband versions?
Here are some pics to give you an idea... all from the same network

Back to awesome after changing router security settings... I wonder how long it will last this time?
