[Q] WLAN Channel Width

Hi,
i just received my nexus 5, but i couldn't find my wifi (i found others and could connected to them) . After i switched the channel width at my router from "Auto 20/40mhz" to "20mhz" it worked fine. Does the Nexus 5 doesn't support 40mhz or is it just my device?
Thanks!

I'm going to try to test some various little wireless things that are going on with it when mine comes in today. For one, they are not allowing the use of channels past 11 which is most likely by design for US spec 802.11B/G.
If I were you, I'd try a few different A channels (52, 56, etc.,) with the 40mhz bandwidth on. I know in the newest code for Cisco AP's I work with, they've gotten a little wonky due to FCC rules for devices with multiple radios.

Internet connection dropping out on wifi

I just received my Nexus 5 today. Got it all set up and I have noticed that the internet connection kind of drops off when I'm on Wifi. I have full bars, but there will be no data. Josh reported similar behavior in his review model on The Verge.
I can't tell if it's a wifi specific issue or not yet. I turned off the "save battery" option under wifi and it's still doing it. The phone will simply stop receiving data in any app. It's not my router. My other devices work fine. I am rooted and do have Adaway installed, but this doesn't affect my Moto X or Galaxy Note 3.
Is anyone else experiencing this issue?

I've been trying to look at current wireless issues and this one is a little new.
So far (No tethering on Sprint - problems with some T-Mo) and that it doesn't see 2.4Ghz channels past 11 and that it can't see some 5ghz channels either.

I can confirm I have this issue as well, I have got my N5 now for 2 days and the problem started yesterday. I have 2 broadband connection at home and cannot receive data on either router, It was working fine until yesterday when the problem started. I have restarted the device several times to no avail. Am not sure why this is happening , do I have to send this back anyone?

I would play around with the router settings if anything.
See if your router is doing 2.4 ghz or 5 ghz.
DO all possibilities before resorting to the exchange.

Oh god, the Nexus 4 had this problem also. Was something with the Qualcomm-drivers. My Nexus 5 picks up notifications much faster, but sometimes I notice a delay for a few minutes (2/3 minutes), with an app like WhatsApp - if it hasn't been in use for a while. With the Nexus 4, I sometimes received my notifications like 30-45 minutes later.

My router is currently set to auto between 2.4 and 5ghz. Also I have had issues with phone being stuck on edge or sometimes just stuck on gprs and it happens mostly just when I need Internet access. Google is disappointing.

And am at work now and the wifi that was working okay yesterday has now stopped working ... I think this has to go back, such a shame.

I can confirm I have the same Wi-Fi dropping issues on my Nexus 5.

Yes, quite a few threads here describing this same problem. Hopefully a mod will join them soon. I too experience this issue. Someone noted Nexus 10 had that problem at launch which Google fixed shortly after with a software update. I noticed Google support forums also have this reported. Fingers crossed for a quick fix from Google!

5GHz networking

Has anyone had trouble with connecting to 5GHz networks with the 2012 GT8010?
I've been unable to. I can see the network but always get authentication issues. This occurred with the original 4.1.2 rooms and now with omnirom after a full reset
My other devices such as a laptop and s4 have no issues...
2.4GHz is just fine even to the same router with the same security settings. Disabling security., dropping g down from ac to a doesn't help nor does switching channel

I have not had any problems personally. I'm running stock not rooted. I have heard other guys having problems though. Sorry I can't help

If you're rooted (or even just have a custom recovery) check here. Turns out that the wrong WiFi config file is being used in US-based units so 5GHz DFS channels won't always work.

thanks. interesting to see if I have issues in those files, but I am actually in the UK in any case.
I tried copying the *mfg* file to *txt* - manufacturing? default perhaps? this had cc=ALL instead of UK, but I figured why not
No difference.....
So followup question - could any UK users post their files from /system/etc/wifi/nvram_net.txt*

and yes I know the mac code is in there - skip that

Does anyone ever got more than 150 mbps rate ? I mean the connection rate between the tablet and router, not some speed test result. On 5Ghz I get 150, on 2.4GHz no more than 72 mbps. I tried 3 different routers, never got more then 150 mbps, and 60 up/60 down in speed tests.

No, and I wouldn't be surprised if that's intentionally set via the WiFi firmware; the WiFi chip is connected to the Exynos via a 50MHz bus that's 4 bits wide, so your effective thruput wouldn't ever be higher than ~180Mbit/sec anyway.

[Q] OPO won't receive calls or SMS when on wifi

Having some issues with receiving calls and SMS on my OPO when connected to my home wifi router, I have searched forums and official OPO forums bit have had no luck finding a solution.
Im from the UK and use virgin mobile (uses the EE network), router is the virgin superhub if that makes a difference
Problem seems to have been happening since I got the phone (begining of Dec 14) but I only became aware of it around new year, girlfriend has an OPO also and does NOT have this issues.
Phone is the global model running stock cyanogen 44, android version 4.4.4
Any help would be appreciated, struggling with this one
Thanks

This has been an off and on again issue for many devices since 4.3 was released. I did a google search and Nexus 5 was plagued by this. There's a long thread on the google support forum, with several OPO posts. The thread is more than a year old, and no root cause has yet been discovered. There appears to be no rhyme nor reason regarding who gets it and who doesn't. I have had this happen intermittently, and a reboot usually solves it. For those who suffer this chronically, the only work around seems to be to keep the phone on 3G preferred. Don't let it connect to LTE.

Yea I found some people talking about the issue on other devices, seems really weird, and yea I did change the preferred network setting to 3g (was previously set as 4g which my network doesn't provide me with) and it worked for a while, however seemed to start again recently, will search for those threads and have a read, thanks for the help
Any other info from people with this issue would be helpful too,
Is it possible that changing my routers broadcast channel would make a difference, could it interfere with the radio?
Thanks again

Still having this issue, yesterday I reflashed stock cyanogen 44 via fastboot method and problem is even worse now, the issue seemed to be every now and again but seems to happen every time now
No longer receiving calls when connected to 3g and WiFi either, only workaround seems to be if I switch to 2g mobile services and I'm still able to receive calls on WiFi
Is there an easy way to make my phone auto switch to 2g on WiFi (closest iv found is disabling mobile data on WiFi)
Thanks, hope anyone has some more info on this
Edit; found a workaround by using g cyanogen profiles to downgrade to 2g on my home networks, but still looking for info on a perm solution, thanks

I´m having the same issue with Wifi turn on, I cannot make or receive calls.
Let me know if you find a solution.

Intermitent issues receiving calls on OnePlus One when in WiFi
I'm also having this intermittent (Not always!) problem of not receiving calls in my OnePlus One when connected to WiFi. This started to happen after a regular upgrade to Android 5.0.2 (Cyanogen OS 12.0-YNG1TAS17L).
I found the solution in forums.oneplus.net. Just search for: virgin-mobile-uk-no-incoming-calls-with-wi-fi-enabled-and-3g-lte in Google and you will find the link. Go to page 3 on this posting.
The issue is related to the fact that calls fail while in WiFi and LTE. Create at least two System Profiles (Settings -> System Profiles). One to change the "Preferred network type" to 2G when connected to any of your WiFI networks, and another that changes the "Preferred network type" to 2G/3G/LTE when disconnecting from any of your WiFI networks.

wifi issues?

So I've had my LG G5 since day one (in the us) and it was working fine, till it wasn't.
Specs: LG-H830 (Tmo variant)
6.0.1
Build: MMB29M
It seems to only be not working at home. I have a 300mbps line with a Google OnHub router. Whenever I try a speed test it goes up really fast to 30mbps and gets stuck there.
I've tried the following:
Factory reset/Cache clear
Factory reset router
Tried a new router (wrt1900ac)
Forgetting the network
Using different wifi names
installing and trying DNSet
None of these have seemed to help.
Two funny things:
I have a Nexus 6p (running N preview) a Pixel C and they both get stuck at 30mbps
My wife's Nexus 5x while connected to 5ghz band will pull 250+mbps
I'm going crazy trying to figure out what's going on here.
Any help would be much appreciated.

I had the same issue that started about 2 or 3 weeks ago and was very frustrated I found out that it affects most Android phones it's due to a lot of the isp companies starting to use ipv6 and Android doesn't play nice with ipv6. The only fix I found was to disable ipv6 in your router settings and that will fix it.

I've tended to notice quit a large speed difference between being connected to 5ghz versus 2.4ghz networks, the latter of the two always being slower. I see that you mentioned your speed was much faster when using the 5x on the 5ghz band. Have you tried setting your devices to use only the 5ghz band? Unfortunately, this is not a permanent solution, as you'll have to allow 2.4 to work again pretty much every time you leave the house, and as far as I've found, there's no way to tell the phone to prefer 5.0 when available.
