[Q] Nexus S extremely poor wifi

Hello there,
i know that this topic has been already debated several times but I couldn't find any solution to it.
I'm running MIUI 1.8.19, android version 2.3.5, kernel version 2.6.35.7-g3cc95e3, baseband I9023XXKB3.
Wifi signal is extremely weak, few meters away from any router and the connection becomes extremely unstable making the wifi experience a total nightmare.
I've been previously tried NSCollab and also different baseband configuration files but nothing seems to get things better.
For what is worth (even though the wifi is bad anywhere and with any router) my router is a Linksys WRT150N running on DD-WRT.
The Nexus S wifi thing seems to be a little bit controversial. Some users seem having no problem with it, some other experience the same problems i do.
Question #1: is that a hardware, software or both kind of problem?
question #2 : is there any workaround that would allow me at least to comfortably browse the internet from my bedroom (5-6 mts away from my router) without getting disconnected every other 30 sec?
Thank you in advance,
D.

You kept a phone that can't hold a wifi connection over a distance of 5m? I'd have returned it on day 1.
It's normal that the distance of WIFI on smartphones is less than say a laptop or pc, but 5m is definitly not normal.
Verify w/ other wifi networks, same problem = return it. If not, bad luck, might be the combination of your phone + the router not working properly.
You can try changing radios to see of that improves your situation, for some it did.

Yes, it is normal having a weaker wi-fi but my blackberry has no problem at all. it is the nexus and it seems to be quite a widespread problem around the globe.
Well i was abroad on business and couldnt return it. Just looking for clues....

I know that netarchy's kernel uses updated wifi drivers, you can try flashing that and see if it does anything.

Hi there,
i tried several kernels: netarchy, matrix and also installed MIUI and also tried the MIUI Brainmaster ROM. Same result: in my bedroom the wifi signal score a miserable -85/90 db. Is there any kernel out there optimized for wifi? I mean, it seems that the wifi weakness on the nexus S is a common problem.
Thank you in advance.

It sounds as though you have a hardware problem or a router problem. I have to go to a room in the other side of my house to get -90 db and even then it doesn't disconnect. I have to get about 200 feet away before it disconnects.

Also it might have something to do with interference on whatever channel you are connecting on but I don't really know enough about wireless networking to help you troubleshoot that.

What i'm wondering is wheter Samsung uses different wifi chipset on the same phone cause i'm not the only one complaining about it. just google "nexus s weak wifi" and you'll see hundreds of people with the same problem.
still wondering if there's a software solution to it.

It has been documented that the Nexus S uses an under powered wifi chip. The chip uses less power but with that comes a weaker signal.

mine seems to be weaker than average...

Yours does seem weaker than normal, but no nexus s has decent wifi range.
What I have done is purchase 2 old linksys wrt54gl routers, have them both loaded up with DD-WRT and then link them (bridged mode or WDS if you prefer) and situate the routers in either end of my house. I have a decent sized 3 bed detached house, with a 70ft garden, I can now get a reliable wifi connection near the end of my garden on my nexus, where as previously I couldnt get to the back door

Might be an old thread, but I just traded my trusty HD2 for a Nexus S and god I hate the WIFI reception on this thing.
I am on stock 2.3.4 Rooted with KD1 radio and 2.6.35.14(Pete's) kernel. Tried just about anything out there, and nothing worked out.
Being a Pure Google experience phone, I was expecting a lot more happening for this phone, but it seems that my 2009 released HD2 was way better for all it had to offer.
Subscribing to this thread!

WIFI is fine for me, same as with HTC Desire, and stronger than iPhone 3G...

Its terrible on my Sprint Nexus.
Where I have an Ipod touch and a LG Optimus, they get an 'excellent' connection anywhere in the house. The Nexus drops the connection all the time, shows a 'poor' 5Mbps connection.
Will swapping the phone do any good?

OK.
I bought my Nexus S yesterday and I was soooo disappointed because of its poor wifi reception... But...
I am a network Administrator and a few minutes ago i just couldn't beleive that about 10 meters away from our Cisco Antennas i had about 89db signal so i started playing... and guess what i now have 55dbs at the same spot! What i found out is that Nexus S doesn't work well with High Frequencies so I disabled channels 8-13 and my AP had to work on the low channels and BAM! everything works fine now (My phone is in stock FW)
I hope I helped

Awesome tip! Thank you so much

I found this channel number which it uses to make no difference to the wifi performance.
I tried channels 1,6,11, no difference.
The phone just has poor wifi.
As a note, usually I don't use the low channel '1', as this gets interference from microwaves more than the upper channels.

just bought a Nexus and and experiencing heavy wifi issues.
I tried changing AP channel but doesn't fix.
Testing signal strenght with a LG Optimus one for comparison:
1- LG: -72db. stable
2- Nexus S: -85db web pages loading fails quite often.
Tomorrow my NS will return to the store. Bye Bye

WiFi becomes Inactive on idle

I have a OPO, Nexus 5, iPad and Galaxy S5 on the same WiFi network and when my OPO goes on idle, it will stay on the WiFi network but lose internet connection after some time whereas my other devices wont. It's not a matter of the settings because I have left WiFi to be awake at all times and even turned off WiFi battery optimization. I'm having a tough time figuring out why this happens. I have to turn wifi on and off to regain internet.

I think I had the same issue, it only worked after I used a different router... I tested it in several places (even in two countries) and the damned thing only stopped working in my home network.
I have no idea why it happened but it only went away with a different router...

My only theory is because maybe my IP is not static and CM on OPO is not made to handle it? I don't get why my other devices work fine though. It only happens at home for myself as well

Could be software, does it happen in CM11 nightlies?
Or maybe is the config for the wlan HW, I think OPO has a Qualcomm solution for WiFi, I haven't experienced this in my Nexus 5 (Broadcom WLAN) or 7 2013 (Qualcomm older WLAN I think).

Bump

I seem to be having the same issue. it's weird. I've been trying to do initial upload from Titanium Backup to my Box account and it sucks...
network is a netgear adsl router with the wifi turned off, wired to a netgear router running dd-wrt, and I also have a repeater that's a d-link dir-615 running dd-wrt... yeah not the simplest setup I know
Would be useful to know if those experiencing the issue have altered screen timeout settings.
I was managing to upload ~30mb at a time, but now it seems to be much less - 1mb or less. I'm not sure if that's because I turned the screen timeout down to lowest (15s) to see what happened, but I've now turned it back up to 30 mb but the amount I can upload hasn't increased with it :/ Well - except for once where I did manage to upload 30mb again - which was directly after I turned off adaptive backlight. but then after that it was down to less than 1mb again.
Really scratching my head here.
There appears to be a similar thread over on the OPO forums - https://forums.oneplus.net/threads/wifi-slows-to-a-crawl.75850/ - I'm posting this in and watching both

Unusable wifi

I'm loving my z3 but for the life of me I cannot get a tidy wifi connection.it doesn't drop the actually connection but just freezes or slows down to an unusable amount.it's not my wifi as I have tested my note 3 on the same connection and it's the same on other networks.does anyone else have this problem or a solution

I am struggling with Wifi speeds on mine. I am having to switch to 4g regularly.
I am not too worried yet as I have 8gb data, but eventually i'll be worried as it runs out lol/
The speed tests show a good speed and ping, but it disconnects or slows down/freezes a lot.
I'm waiting on updates.

Thanks for the reply.I get data fine over 4G too.the chappy wifi is annoying as I have wifi everywhere I go...but no 4G signal at home

Confirmed, same experienced here.

Didn't the z1 have this problem

That may depend on the router or its settings. Had the same "freeze" issue when connected to my AVM 7490 router set to use channel 100 for 5GHz. Ever since I changed it to channel 48 no more such problems so far.

My bluetooth is similarly awful, in both range and functionality.
WiFi constantly drops and freezes, always has a weak connection compared to my other devices.
Sony have always cheaped out on wireless chips for any of its hardware products, especially things like playstation products (PS4 wifi is the worst I've ever seen), but I didn't expect it for a £500 smartphone!

Ditto. Great 4G on a 10GB cap.
But shocking wifi. It won't connect to I my router half the time, and the other half drops the connection after 10 minutes.
Out of various devices it's the only one, and I've had more devices on.
I'll change the chanel, clear dhcp allocations and usual stuff and see if there is any difference

I seem to of narrowed my problems down to the router at work so Yaay lol.
As for Ps4, I think they're getting some unfair stick. I have mine connected to crappy BT home hub and the wifi connection is excellent.

Swapped it for another router (I got a random duplicate from my isp, glad I kept it) and the problems gone. Mostly. still drops from time to time. but usable

It seems to be random. My mate has a launch day model like me, and his WiFi is excellent to his 6 year old Sky wireless G router.
I have the newest homehub, one of the best rated routers on the market right now, and the connection from my PS4 to it is incredibly unstable. Every online game lags horrendously, especially BF4. Plus on my 80mb connection it allows for 3MB/s downloads at most. With an wired connection, no lag at all, and the download speed hits max every time.
The same thing seems to apply to the Z3. So its a sony thing. My first Z3 the wifi and BT were unusable. 3rd Z3, and wifi is the best I've ever used on a mobile device, and I havent even connected to my AC network yet to try. Bluetooth I've yet to try though.

AVM Fritz!Box here, newest model, got it when I moved because I'm on a business contract, even though I didn't want it. Has a multiuser NAS, SmartHome and whatnot, and one app for everything.
But when on WiFi with my MacBook Pro, ping times sometimes go up to over 250 ms, then back down to the usual 12. I have no idea why, it doesn't happen when connected to it via Ethernet. Bandwidth itself never seemed to be an issue though, and the Z3 performs great with it though.
TL;DR: Trying a different router can make a huge difference.

I was having the same wifi issues...my network was saved, I kept re typing my password thinking maybe I entered it in incorrectly but kept getting the "Authentication Failed" message. I was able to get the phone connected to my home wifi buy simply hitting the "Forget" option...then it automatically read the IP address and accessed the network...smh hopefully this helps for Everybody else....or some at least

Moto X Play WiFi Performance Issues

Hey guys, got my Moto X Play delivered on Tuesday and so far I'm loving nearly every aspect of it, the camera and the large battery are definitely an improvement over the Moto X 2014 that I upgraded from. However, one issue that seems to keep bothering me is the wifi. Basically it seems to constantly drop the connection for no reason at all, my Internet at home is provided by virgin media and the virgin hub is in modem mode and I'm using a TRENDnet router to broadcast wifi. No other devices in the house seem to have any issues connecting with this setup.
The moto x play seems to connect fine to both the 5ghz and 2.4ghz networks but after a couple of minutes they just seem to loose signal. The wifi icon in the status bar doesn't change to imply that this has happened but chrome or Netflix, etc will just get very unresponsive. The phone has been restarted several times since I got it, I have also tried 'forgetting' the network and re-entering the password (on both 5 and 2.4ghz) and I have also tried the setting in lollipop to change the wifi type from auto to 5ghz only and to 2.4ghz only but nothing seems to have any effect. Does this sound like teething problems that could settle down to anyone else or does it sound like a faulty device?
Has anyone else had any issues with this phone?

I had these issues when I bought my tablet and thought maybe it was the tablet. Then I tested the tablet at my brother house who had different service provider and it worked fine.
So maybe give it a go at a resturant or a friends house and see what happens.
P.S I was with Virgin Media aswell when I had these issues no idea if they are connected.

Thanks Geordie Affy, i'm actually going to be at my parents this weekend so i'll give it a go on there and see if the situation improves
Hoping it settles down as i really don't want to go to the effort of returning it to amazon

Its most likely your router not your phone causing these issues.

No problem ... keep us posted [emoji106]

Ok so, bit of an update.
We had a visit to the mother in laws last night and i tested this issue with their wifi (provided by BT, using all original BT equipment) and still got the same issue. I'm concerned now that this is a problem with the handset.
Any other thoughts on what could be causing it or what i could try to cure it?
Another bit of info i've discovered recently is that even on 5ghz when connected to wifi the phone really seems to struggle to multitask (from a web perspective) i.e. if i'm updating apps on the play store i can't successfully browse the web on chrome and vice versa.

I want to confirm that I have wifi issues too. Just received my device and wifi it's not working. I never had any issues with other devices in my house and I have lots of them. Phone seems to be scanning indefinitely.
Have a look if you have the same exclamation mark over the wifi icon?!
Any updates on your device so far?

No, mine is even more frustrating in that the icon remains the same whether I'm connected or not. I've spoken to a guy at Motorola on live chat this morning and as I'd done all the things he had suggested already he recommended doing a factory reset. At least that's one of the big advantages of this phone is that I can backup all my stuff to my sd card and eject it before reseting. Should make it a whole lot easier.

The only thing that seems to have made any kind of difference, and really, it could just be coincidence (as I don't know how these things work at a scientific level) but I reset the router this morning I. E. Turned it off waited a minute or two and turned it back on again and that seemed to improve things slightly. In fact I thought it had cured it as this morning I was unable to even get through one song on Spotify but since the reset I managed to get through an album and a b8t before the connection borked. Since then the signal had dropped out once or twice but not on the same scale as before.
Debating whether to bother with the factory reset now...

I somehow got my wifi working but now I am browsing and whole browsing experience no matter what website I am in is stuttering and lagging .Simple browsing in Google Play store remains the same jerky ,same thing observed on facebook app.
Even my friends Sony M works much smoother. I have tried both H+ 4g and wifi performance very inconsistent. Don't know what to think

Wifi is definitely slower on my Moto X Play than it was on my Galaxy S6. Just going by memory (which could be wrong), I want to say that my LG G3 and Galaxy S5 had better wifi than the X Play too. I only had it for half a day, but the 3rd gen Moto G even seemed better.
I do have an odd issue with the wifi that is annoying but easily fixable (thankfully). Every time the phone boots up, I get the exclamation mark over the wifi icon and it just runs off my mobile data. If I toggle the wifi off and back on, then it connects properly to the wifi and no more exclamation mark. I have to do this every time I restart the phone though.
Hopefully an update will fix this.

How odd it is . I was playing with Moto G 3 gen and it was smoother that Moto X play.

What I am now finding strange is at my parents the wifi has seemed fine! However amazon are already sending me a replacement unit today. Not sure what to do now.

Yeah I thought it would be the case. Had issues like this but never figured out why it happened tbh. Fortunarlely after a couple of months we changed our internet to BT and worked a treat (Minus BT going down haha)
Sent from S3 via Tapatalk App.

I've had issues with this as well. Appears to be connected but no data transmits while every other device works fine. Only happening on one old router not all. May have something to do with Motorola dropping the "ac" WiFi standard on this phone. More annoying is the phone being slow to pick up a cellular signal after leaving WiFi. I've had this happen often and for as long as 5 minutes.

I got my Motorola x play about two weeks and I've just noticed a few Wi-Fi issues. I'm connecting it too the super hub router provided by virgin media on the 5ghz signal and it was fine when I noticed if I held the phone by the top half in the palm of my hand instead of the bottom half, the signal strength shown by the icon in the top right hand corner would drop by half. Is anyone aware if the phones Wi-Fi aerial is on the upper reaches of the phone?

I too have noticed this. Thought it was all in my head which is why I hadn't mentioned it previously lol.

I haven't so far been able to replicate the issues you guys are facing with WiFi. Performance seems to be in general at least on par with my late Galaxy S4.

This could also be a Android 5.x issue. I'm facing similar problems on my LG G2 running SlimLP. WiFi and also cellular seems to be dropping for no apparent reason and I have to manually reconnect. Interestingly though, my Nexus 7 WiFi 2013 doesn't have these issues running UberCM 5.1.1.

other problems with WiFi.
I have this strange problems. See if someone else has the same.
I used googled maps for GPS me to destination. When I am driving WiFi cut off and the phone use data. When I am arrive at destination. I go to McDonald. The phones can't connect to free WiFi at McDonald's. Even this is a saved network. I turn off then on the WIFI, still not connect.

WiFi issues

Hi,
I have some WiFi issues. After a time no data can be send and received over wifi, but I'm still connected. I have to reconnect wifi and after this browsing the net is ok.
I have this on 3 different wifi Hotspots
Anyone also have this issues?

I have it too on LG G4. Anyone know how to fix it?

I have the same problem if i move to fast away (about 15m not out of range).
It could be my dual 2.4GHz/5GHz Network, but I'm too lazy to test it

I have it on both 2,4 and 5 GHz.
The last hour I can't connect to any SSID. And suddenly it works.
I Hope, that this is a software/firmware issue and they fix it in the next update that hopefully come soon.

Boy, am I glad you are making this thread to report on this issue! I am having the very same problem and it is driving me bonkers!
I am trying to review this device for my YouTube channel and this wifi issue is NOT helping. So far I have tried booting in safe mode, connecting to other wifi networks and reconfiguring my internet to no longer bridge together the 2.4&5 GHz bands.
What I am finding is that safemode has no effect but I can connect to my in-law's network just fine. When I changed my network settings I was able to show that it simply just doesn't want to fetch data from the 5GHz band. It works just fine on the 2.4GHz band but now I am not enjoying my potential wifi speeds. Sony really needs to fix this. The last thing I was going to try was doing a factory reset on the device but I don't think it will matter.

If you have wifi issues, try to change channel, etc- from 13 to 11, or try update wifi firmware.

June update is around the corner, highly likely next week. That one might include fixes also.
But as an established youtuber I would reach out to Sony directly to get confirmation on the issue and potential fix.
Also place to get direct answers would be talk.sonymobile.com

I cant say I've had any issues, but I'll keep an eye out. I've streamed music and radio stations for hours with no issues, and I'm guessing this problem would present itself there.

I can confirm I am also having this issue on more than one wifi connection.
I hope this is a software issue.

I can't explain, but the last 2 days no issues. WiFi works without problems on both 2,4 GHz and 5HGz.
Also the "bug" in battery stats with high WiFi time (more than 300 days!!) is gone.

I also have a wifi problem , but I have two access points linksys ea4500 and wrt1900ac on the first one it works perfectly on the second one stays connected but there is no internet, My issue specifically applies to wifi ac otherwise it works well... similar to my pervious lg g4

Same here. I can confirm that this can happen even on 2.4 or 5ghz wifi networks and that it's not a channel issue because I live in countryside with barely any other wifi networks.
But the problem is so much strange. For example, it will stop to work randomly when transfering data, watching youtube videos or such things but this never happens when using chromecast. I can pause, play, the videos, etc. with no issues. Like if it needed some heavy traffic to start having issues.

Same issue on my xz premium. Using both 2,4 and 5GHz at home. Having the issue also on all of my 3 WiFis at work.
WiFi is draining out my battery. 60% or more and around 30days of usage (having my device for a week now)
At the same WiFi at home are several devices connected without any issues. Xperia X compact, Z5 compact, ipad, Sony Soundbar. Sometimes my XZ Premium shows me "connected to WiFi without Internet"
This is the worst Xperia experience ever

Hej, I have create a sony mobile post about our issues with xz premium wifi problem, if we post in sony mobile support page there will higher chances to be fixed.

I've also posted the same. And many others also. Let's see what happens

My WiFi says it's been running for 34 days+ but my connection on 2.4 has been good and solid from the start. I have no problem with there being an internet connection. I am fairly certain that the two issues are related in some way and some are having more problems than others.

I haven't had any problems, but then I did a complete reset of the phone a few days after I received it. When in doubt, that might be something you can try.

Turn off Smart cleaner.
That's the cause of WiFi disconnection and battery drain.

I have no wifi issues (2.4 only - no 5 for me) but it says that wifi has been running for 669 days. LOL
I sure hope Sony fixes these silly bugs.
