[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..
Sent from my Droid using XDA App

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] WiFi strange behavior

I got my daughter her tab 7.7 about 6 months ago & had been going on perfectly. Android version is 3.2 & I have no easy measures to update for the time being.
For internet connection she uses only my WiFi secure connection. It was working fine all this time.
Today she can't log to her Facebook account via the Facebook app. I checked it out to find that I can log in via the browser but not the app. I thought it may need updating and tried Google play store but I was astonished to find it not working too as it gives me "No Connection. Try again".
I noticed that the WiFi mark is white & not showing the green strength marks, but connection is confirmed by the WiFi name. I was shocked when I tried the software update from "about" when it gave me the "no connection message" despite working WiFi connection. Samsung app is working perfectly & I can update its applications.
Also funny thing happened, when I tried the browser it kept giving me certificate errors many times.
I tried the VPN as I googled around but nothing changed. Same problem.
Switching off & on didn't help either.
Any Clues??
Thanks

Most strange thing happened.
Everything is back to normal without me doing anything.
I left the tab for a while while writing the previous post.
When I came back I found the app update mark showing up, I turned on the WiFi & touched the update icon, the strength signal showed in the WiFi & update started the goggle app. All went normally. Facebook app worked & even the browser certificate errors disappeared. The software update in the "about" worked fine & checked & found no updates.
What is going on...
Can anyone explain to me what's happening?
Thanks

Try Power Cycling your modem/router. That often corrects connection issues. Presume other devices were connecting just fine?

Poor cellular data connection even though full signal strength shown

I'm having big problems with my cellular data connection. I keep getting the following intermittent problem . . .
My phone will display full signal connectivity i.e. 4 bars with H displayed, However I am often unable to make a data connection.
If I use a network monitoring app such as "Network Signal Info" it shows that I have data connectivity (see 1st attachment), however if I try to access a data service there is no connection. Running an app such as "Ookla Speed Test" will result in a warning showing "Network communication issues" (see 2nd attachment). Data services refuse to work (the 3rd attachment shows a Google Now search)
This has been a persistent problem irrespective of my location. I have even swapped SIM cards with my wife who is on a different network (I'm on 3, she's on O2) and still had the problem - this indicates it's not my network provider but the phone / software.
I'm running stock Android 4.4.2 which has been rooted. The only mod I'm running is Xposed Module. However even disabling this still results in the problem.
The lack of data connection can occur for a few seconds or even hours. Turning the phone off and back on again (or putting it into Airplane mode) can sometimes fix the issue, but not always.
I've re-installed cleared the caches and re-installed Android 4.4.2 but this not made any difference.
Any help would be much appreciated as this is becoming increasingly frustrating.

I added the two build.prop edits to disable dormancy and change hsxpa to 3 (ro.ril.fast.dormancy.rule=0 and ro.ril.hsxpa=3) and also changed radios. You might try those two.

Thanks @MrObvious I'll give the build.prop edits a try and update the status in a day or two

Internet connectivity problems

Hey guys,
I have a problem with my nexus, I've noticed that my internet on my phone is acting quite...strange to say. I have a dual band router(d-link 880l) and on my phone I only use the 5GHz one. it's the only device in my home that has problems.
The problem is that when searching something using the google bar it takes ages until I get the desired result, on youtube app sometimes when I open it ,it won't load anything,the second I close it and open it again it works,some videos just refuse to start until i restart the whole application, sometimes whatsapp doesn't connect to their server I have to restart the app to get messages, or to see las act of people,on facebook messenger is the same story,when i send a message it won't send ,it acts like I have no internet connection,until I restart the app. Ironically I get CONSTANT 81mb/s download and 91mb/s upload in speedtest.net app.
I really don't know what to do ,i've forgotten my network,tried connecting on 2.4GHz,put my wif i mode only in 2.4GHz,enterd recovery cleard cache partition,unninstaled whatsapp,youtube,fb messenger,google app,deleted all google play services data,restarted phone,neither of those fixed it...
Can you help me...?

Are you running the latest stock ROM or some other ROM/kernel combination?

I'm running rastapop 5.1.1 LMY48I with elementalx 4.04 since august 2015 with no fancy kernel settings or mods, just adblock and xposed over the top.I started to have this problem since november.
I did a factory reset on the router and I still have the problem.

To rule out software being the problem, I recommend flashing back to stock to see if the issue goes away.

I own a D-link DIR-850 (dual band AC router as well) and I am experiencing kind of the same problems. I have a Nexus 5 with latest firmware (MMB29S) but have had these issues for a while already. My girlfriends HTC One mini suffers from these problems as well. Most annoying is the seemingly random disconnects from whatsapp, I guess caused by Google Play Services being unreachable as at that same time also the Play store and other services relying on it are unreachable. Not sure whether this is an Android bug or caused by a bug in the Dlink router, which off course has been reset to factory defaults and checked for updates several times
Strange thing is that at the times that the Play Services are unreachable, other (plain internet based) services such as browsing with Chrome are working just fine.

I did some research on this compatibility issue between an android phone and a d-link router after I discoverd I'm not the only one.
The problem turned out to be some bug that is present in a way or another in android since lollipop , I think that lollipop(my case) is getting stuck when trying to do a DNS lookup ,but the problem is that it only happens on my home network, I don't have any problems at my friends wi fi or a public one. So my router isn't playing well with lollipop or the other way around.
The only solution I found to this problem is to disable ipv6 on your router or on the phone. So I did ,made a script that changes a value in a file, here it is : "echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6". With this I disabled ipv6 protocols on my phone(i've verified "disable_ipv6" file just to be sure that the value is "1") . Everyone bragged about it that it sloved their problem. Well guess I'm not that lucky,the problem still persists on my phone...
I've tried everything in the book...guess that this brand new 150 dollar router is not that impressive as they say...
I don't really want to factory restore my phone,I want to be my last option...the guy above me said that it did the factory reset thing and it didn't work so guess that it isn't an option after all...
If someone can help me(us), i will be very pleased...

At my workplace we have an Asus RT66NU providing the wifi, where I have never had any problem with this.
As you are suspecting it has something to do with the ipv6 stuff, I'll be experimenting with this a bit to see if something changes. First test is putting the autoconfiguration setting to SLAAC+stateless DHCP.
Next step will be disabling ipv6 at all.

I tried with PPPoE( my internet connection ) on ipv6 that is shared with my ipv4 session with SLAAC + stateless DHCP and stateful DHCPv6 . At first it was promising but in the end it didn't really solve my problem. Just for the record ,I had my ipv6 settings before on local connectivity only .

Strange mobile data problems

Hi.
I noticed that after being connected via WiFi for a longer time, e.g. during work at the office and then when I go out of WiFi range and phone switches to mobile data some apps don't seem to be able to receive mobile data or don't see the connection at all. E g. Waze (shows "waiting for network") and OnePlus community app can't read contents. Chrome browser works without issues at the same time.
Only reboot fixes it.
Anybody experiencing similar issues?

Not sure how related it is, but I was having problem with my vpn. When I got off wifi it would not automatically connect and apps wouldn't have data, there were some other symptoms that I don't remember now. Anyway going to developer settings and turning on mobile data always active fixed the problem for me, might be worth a shot.

Same here

Yeap, I use nordvpn, ones I leave my house using wifi and vpn, I loose data when switching to lte.
I don't have this problem with my op6.

Thanks for your input. So it looks like it would maybe be worth it posting about this issue in the OnePlus support forum.

I just noticed default 4G network mode is not the one I used to have on all my previous devices. (See attached picture). I'll try to switch to LTE Global and will be checking whether it changes anything.
