[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.

*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.

[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] 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.

[Q] Strange Wifi/Mobile Data Issue

Ok so I have two of the universal Moto G LTE . We were running the unofficial cyanogen 11 perfectly for afew months and on one phone became unable to connect to our home wifi, shortly afterwards the other had the same issue. Flashed a LP rom but wasn't suited to the stability of it atm so settled on Slim-peregrine-4.4.4.build.9.0-OFFICIAL-8310 with Slim-Addons-full_gapps.4.4.4.build.9-20150107, and the issue was gone. However on the other phone after a wipe and clean install of the same rom and gapps the issue persisted and further would not connect to the wifi or it mobile data though still has perfect signal for calls and mms.
I'm no tech wizard but I have tried the following;
PHONE BASED
Flashed every kernel and every rom in the Moto G LTE forums (Yes ALL but not every combination)
Tried variations on the airplane mode
Fastboot erase modems1&2
Reverted to stock RETUS_XT1045_4.4.3_KXB21.14-L1.23-4_cid9_CFC.xml.zip via manual mfastboot cmnds & MotoFlash
Changed filesystems
Connected via direct IP (still no internet though it says connected)
ROUTER BASED
Reset it (Duh)
Tried a different router
Enabled/Disabled MAC Filtering
Once I realized the mobile data was out to though stopped messing with the router.
Currently it is running the above mentioned SlimKat and works wonderfully except no mobile data even with the correct APN info and fails to authenticate wifi. I'm at a loss, did the phones ethernet chip or w/e it is die maybe?
I'll provide any logs asked for if I can get them... It's my wife's phone that is having the problem meaning I really need to fix this or suck it up and buy a new one. Appreciate any help in advance and if not I understand, thats the game when messin with this stuff as a novice.

As an update, upon the monthly renewal of the data mobile data is still working. Just the WiFi is still not working.

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 .

Mobile network internet access stopped working

Yesterday was like any other day, I took the bus to work and enabled mobile hotspot on my Oneplus 6 so I could do some work. On my way home in the afternoon, I did the same thing. This time however, I had exclemation marks on the mobile network symbol in the statusbar. Tried enabling hotspot anyway but there was network. Rebooted the phone but still the same issue. Oh well, I thought it was just my carrier then. When I came home to my wifi, I checked my carriers status information on their websites and there was no disturbances. Then I restored a backup which failed and I had to reflash the phone entirely with the latest pie zip. Today, I still don't have any network on my sims. I use two sims but they are using the same carrier. I also asked around my friends which has the same carrier and they have network...
I would understand if something might have happened when I reflashed the phone last night but that does not explain the sudden malfunction of the network on my bus ride home, the phone had worked flawlessly for a whole week.
This thread seem to be about the same thing and I tried the solutions regarding clearing caches and settings but it did not work:
https://forums.oneplus.com/threads/...ot-working-but-network-bars-are-there.844978/
Could it be something with the IMEI number? But it doesn't explain why it stopped working out of the blue. I can see both my IMEI numbers in the settings and I have also tried install Magisk 17.2 beta as suggested by another user. I think I still have a backup of the modem on my pc. However this is from when the network still worked and then suddenly stopped working.
TLDR: I have full reception, Calls and SMS work, there is just no Internet connection.

Just to be sure, datasave is turned off?

Yep, that is off. I have also reset my APN setting and double checked them with my provider, it didn't help.

No hotspot
I'm having a similar issue, I updated to android p stable and since then I can't use hotspot. It turns on fine and says devices connected but internet doesn't work on the connected devices. This seems to be an issue with Android P because my gf also has the op6 and I tried hotspot on hers before updating and it worked fine, then updated and it stopped working for her too. I have also tried clearing cache and manually entering the APN. I need to be able to tether to my laptop and tablet for work so anyone solution to this problem would be highly appreciated.
Thanks.

Although the problem I decribed in this thread isn't the hotspot problem, it was caused by my carrier. But I also have issues with hotspot, my laptop has trouble finding the wifi from the phone.
