[Q] Not connecting to AC wireless 5GHz - ONE Q&A, Help & Troubleshooting

I've tried searching for this but haven't found anything. Apologies if I am doubling up though.
Anyway:
I recently got a router that can broadcast a 5GHz AC wireless channel. I set it up and got my wife's phone to connect to the 5GHz channel perfectly fine, but my OnePlus One will not even see the channel.
Weirdly though, if I switch the OPO to detect 5GHz bands only, it picks up my neighbours ac wireless, but still won't connect to mine. I've entered the details manually with no luck at all as well.
The SSID's are completely different.
Any ideas or help would be greatly appreciated.
I'm runnning Cyanogen OS 12 (12.0-YNG1TAS2I3)
phone is also rooted with TWRP 2.8.7.0

Change the channel the 5ghz broadcasts on
Mine works fine on 5ghz

I changed the channels with no luck. It seems to refuse to connect to just my router.

So if anyone looks this up because they also had this problem: I fixed it.
Turns out this was a problem with the ROM. I switched to the CM nightly builds and it connected to my AC wireless channel fine. It also allowed me to send and receive MMS messages again, so there was clearly just something wrong with my build of CyanogenOS.

Anybody having wifi problems?

It seems my phone keeps dropping wifi randomly, even as I'm writing this my wifi has dropped. My computer doesn't seem to have any problems with it. Wifi sleep policy is set to never and when it does connect to wifi its full strength.

I'm having problems with my D-Link wireless router. Devices can connect to the secured WPA/WPA2 connection with the password, but it doesnt really do anything except for show its connected. I've tried resetting my router completely. I think it has something to do with my Verizon router it goes through. i.e. When I type in 192.168.0.1 or w/e the default is for my router, it used to bring up access to my Verizon router instead of the D-link. I noticed the cables going to the Verizon router where not plugged in correct, (slots 2,3,4 instead of slots 1,2,3) and that fixed the 192.168.0.1 problem, by bringing back the d-link page. However, still not able to recieve internet on connected devices. (I think its somehow connecting to the Verizon router instead of the dual band D-link) --** I use the 2 ghz , not the 5
What's weird is that both my stock captivates would do the same thing. Than after I flashed them the problem completely disappeared.

Strange !!! Got my new Inspire yesterday, connected to WiFi and have been having trouble with my Airport Extreme ever since.
Airport worked perfectly up until then, ever since I keep having to reset the router to get it to work.
Anyone else having sudden trouble with their routers ?
Not having any.problems with the.wifi, quite impressed to.the contrary.
I did just finally upgrade.to a newer midrange (price) belkin.
Our.older netgear was a.nitemare for peripherals.

Fixed the problem. My slink router was conflicting with my Verizon router. I checked to see what my dlinks gateway/DNS IP was using some commands in the run/cmd and had to manually asign IP addresses.
The gateway and DNS should be the same.
Subnet 255.255.255.0
IP address is the phone's IP used to connect

If anyone is having problems obtaining an IP after extended periods of not being connected to your wireless router, try setting ur router to channel 11 and setting security to WEP. After I did this, I haven't had a problem reconnecting whatsoever.

Connect phone wifi hotspot to Linksys wrt router - Issues

I have my Linksys wrt54gs flashed with ddwrt and it allows me to put the routers wifi into various modes such as client mode and repeater.
Basically I want to have my router connect to my Nexus S (or Panache) wifi hotspot, thereby allowing the devices connected to my router by cable to access the internet.
I had this working for months, then one day the PC on my LAN reported it had no internet access and I haven't been able to get it working again reliably since. The router and phone hotspot will connect, but the phone never seems to want to issue the router an IP, so no internety goodness.
Now the phone not wanting to issue the router an IP problem was there from the beginning. I initially solved it by setting up a static wan ip, gateway, and DNS on the routers wan configuration page. This worked well for months, until suddenly it didn't.
Now I've fiddled with it quite a bit and can sometimes get it working on one phone or the other, but it's never really consistent. It might work now, but if I go out and come back l (or try to switch between phones) getting it to work again can be a real hassle.
Anyone have anything like this setup and working reliably? Enquiring minds want to know.

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.

Brand New Nexus 5 Doesn't Connect To Home Wi-Fi [URGENT]

I bought a nexus 5 to replace my galaxy s4 which died a couple of days ago.
My home router is a Netgear D6300 and everything (pc, tv and phones such as iphone, samsung and nokia can connect just fine).
My nexus 5 was delivered today and i spent the last 5 hours to get it working with my wifi but NOTHING worked (and, i'm not joking, i got to the point of almost throwing it out of the window).
I tried enabling SSID broadcasting, changing "security options", changing channels, disabling 5ghz network, i also enabled the guest network with no protection but nothing worked.
The only thing i noticed was the when using particular channels (5-6-7) the phone would say "connecting" for a few seconds but then it would go back to "saved,protected with wpa/wpa2".
I also changed some wifi settings on my phone (i disabled wifi optimization and i forced the phone to use the 2.4 ghz network only)
Sometimes it stays on "saved....." and doesn't even seem to try to connect.
After a while i tried creating an hotspot with an iphone 5s and my nexus connected in a second and everything was working.
So the problem should be in my router settings but i already tried everything (and besides everything else but the nexus works just fine).
I'm really desperate because i use this phone for work and i need to get this working asap.
I also managed to update to android 4.4.4 using my mobile network but i can't update to lolipop because it would use all my remaining 3g network data.
Btw i did some heavy modding on my galaxy s4 so i'm not a newbie to android.
I'm also willing to pay for support but to be honest i'm really disappointed that such and "acclaimed" phone has problems connecting to a wifi network that works with basically everything.
Sorry if I missed it in the post, but did you reboot the router.

Yes but it didn't help.
I've had 4 N5's in my possession over the past year or so, and not a single one had any issues connecting to any WiFi network, including Netgear routers. Your problem is either specific to your particular device or your router and not with the N5 in general. I assure you, the N5 deserves all the praise (and criticisms) that it has received.ave you tried a different router? I know you used it with your iPhone's hotspot but I mean an actual router? Also, have you tried resetting your router to defaults?
Are you using MAC filtering on the router?

I just tried a dlink router on my home network and everything works!!!!!
But i want to understand why my D6300 doesn't work with the nexus (its configured the same way as the dlink).
Any suggestions???
In the meantime i'll reset the D6300.

Nope, i've disabled it.
And btw i read on some forums of people using my netgear with the nexus 5 and everything was working just fine.

If your router is handing out DHCP addresses it may have run out of addresses if you have many wireless devices connecting infrequently. But I would thing a reboot would have cleared that up.

WiFi 5 Ghz issues

I've noticed whenever I connect to a 5Ghz network, it's complete garbage. At my house, when I connect to 2.4 Ghz I get a consistent speed of around 75mbps, when I switch to 5 Ghz, I can't get more than 20 consistent. Sometimes it works super quick for a second, and then anything I try to do, web surfing, videos, downloading apps etc.... just suddenly stop as if I have no connection and never start again.
No issues here with 5ghz - can only suggest resetting router and phone, otherwise perhaps you have a faulty handset.
Also no problems here. I find the range off the antennas great.
Did several speedtests and no drop outs.
Just got mine and AC 5ghz works great. Getting 235/23 mbs on my home internet.
I have the same issue. Inconsistent connection and slow speeds on 5ghz, only way to fix is a router restart, but then if i turn off WiFi and re-enable, the problem returns. Possible IP issue?
When I received the phone 2.4ghz was fine (110/110) but 5ghz was not (550/3).
I had to go to setting > WiFi > Advanced (in the "..." menu near the gear on the upper right corner) and uncheck Wi-Fi optimization.
Then I got 550/250mbps
Not sure if it's relevant to your problem, but you could try that.
Good point. Seem to remember something similar on the 10 too. Thanks!
You're welcome Hope it will solve your issue.
Unfortunately, that didn't work. Got a replacement handset yesterday, just to be sure that it wasn't the phone, same problem happens?!
I use a Linksys router, if the op is still on the thread, what about you? Have no issues on other 5ghz networks. Well, the other 2 that I've connected to.

I think I remember a bug with some Android phones on 5Ghz if IPv6 broadcasting was enabled in the router. Are you using this? Tried disabling it?

Thanks, i'll give that a try. I've never had this issue with any other phone, it's very odd and actually frustrating. While I can fix it at home, I wont be able to modify router settings when out and about, so if I struggle to get WiFi on the move, i'll be paying a fortune for data, which may force me to return the phone.
Just tested mine with Virgin Media router and WiFi optimisation turned on. Maxed out at 220Mbps

I'm noticing issues on a Linksys router as well. My wife's old M8 had an issue that would go away when Bluetooth was turned off.
I messed with settings tonight and it seems more stable. I just made 2.4 and 5 on SSID, and changed all band settings to Auto.

If its happening on other connected devices on your wireless network either 2.4 or 5Ghz try changing Router channels.
I've seen this happen on 2.4Ghz. Turns out since I lived in a pretty Wifi congested area the channel my router kept picking as "The best" was actually 6 and all the routers default to that channel. Literally that frequency was so bugged down my internet went from hitting 60-80Mbps down to Kbps. Wifi Analyzer showed all 12 channels were pretty full. I switched to 5Ghz only and immediately saw a difference, but the few channels I do have on my router are getting congested nowadays too.
Nowadays whenever my phones Wifi speeds hit the floor I do speedtest on other wifi devices and Ethernet speeds. If theres a significant difference I quickly use Wifi Analyzer to see if its time to switch channels.
when i got my htc u11 unlocked i had problems with the wifi not connecting at all or if it did it would disconnect. i found that there was a software update so i downloaded it on my mobile data. once installed everything started working correctly. mine will connect at 866mhz to my dlink-879 ACN router
The ivp6 thing or whatever is what I did when I got the m9, it wouldn't connect to my wifi at first and it was 5ghz

I forgot about that option. Had issues with my 10 when it came out a d that fixed it, so far it's working on my 11.
Still having issues with this. Tried above suggestions, not specified a channel, currently set to auto. My M9 and 10 have no issues holding a fast connection. Getting a bored of it now, as trying to stream Le Mans and it constantly cuts signal.
