Wifi 802.11n 5Ghz working for anyone?

I found the option in the settings where the band can be forced to 2.4, 5 or Auto. On either Auto or 5 the N4 doesn't "see" my 802.11n router (other clients are connected to it just fine). Only b/n/g seems to work for me. The router is a Linksys E3000 running DD-WRT if that matters.
Anyone else?

Well, the Nexus 4 doesn't support 802.11a (see wikipedia etc.)
But 802.11n at 5 Ghz should work.

Actually, it does.
Wireless RF Module - Atheros WCN3660

Manufacturer: Qualcomm
Bluetooth: BT 3.0/4.0 Low Energy
Wi-Fi: 802.11 a/b/g/n (2.4/5 GHz)
FM: Hardware supported

I don't have wireless A, but one thing to try. Is your 5ghz and 2.4ghz broadcasts named the same? For instance on my wireless N setup I have the router broadcast ROUTER5 and ROUTER2.4 so I can specify which band to connect to. This has eliminated a lot of trouble of my wireless devices not choosing 5ghz when I want them to. So my Nexus4 just connects to ROUTER 5 and I know it is 5ghz.

The SSIDs are different for "5" and "2.4" for exactly the reason you mentioned. But no matter what I can't see the "5" SSID from the N4, while either wifi clients can see both at the same time. The router support simultaneous 2.4 and 5.

Yes. 5Ghz works.
I use it in my house. I'm on it right now with my N4.
Check the security on your router.
You should have a WPA2/PSK AES encryption or leave your network open.
You'll also want to verify your router is broadcasting.
Since your router was flashed with DD-WRT, verify you are in mixed mode or some sort of N G combo.

Thanks for confirmation. It's strange that the phone doesn't even see the router at all, I tried various mixed modes, channels, SSID broadcast is enabled, etc. Other clients have no problems with the router.

I haven't tried this yet, but from reading other reports it may be the case that the N4 (and the N10) only support the 5Ghz band with 20Mhz channels, not 40Mhz. My router is configured to use 40Mhz only so that might explain why the N4 cannot "see" it.
http://www.dd-wrt.com/wiki/index.php/Wireless-N_Configuration#20MHz_vs_40MHz

running my Nexus 4 on 5GHz N mode on a Linksys EA6500. My channel width is set to auto so maybe that is why it can be seen and used.
General question though, why have you chosen to use 802.11a anyway? What benefits are there? (honestly curious)

Sort of off topic, but who the crud uses 802.11a?

The subject of my topic is wrong. It should have said 802.11n on the 5Ghz band, not 802.11a. I edited the subject now.
I prefer 5Ghz when possible because I seem to be the only AP on that band whereas 2.4Ghz is crowded.

I have the same router with DDWRT also and my N4 cannot see my n router either. I will look into the band settings tonight.

Just chiming in, Linksys E3000, DDWRT and my 5Ghz network works like a charm

5Ghz works for me just fine.

still having wifi issues, wddrt flashed firmware(iv'e tried all settings) wasted 24hours i think trying to figure it out, solid connection but wifi seems broken, can't download stuff but can browse google playstore
my other wifi devices have NO ISSUES at all with this router
cannot run speedtest, can only run ONE certain type of texting app(strange) others won't connect online
its like my n4 has a 'firewall' or something
seems my best option is to pick BG-MIXED mode! alot mor apps connecting to the internet now but not all! at least im getting progress

Change your channel to 40 or 48. Mine didn't work before but after changing my AP channel to 48, my N4 can see the 5GHz AP now.

Thanks alot ! I had this exact problem with my Tomato-flashed Linksys E3000. I changed the channel of 5ghz from Auto to 48 and voila, Nexus 4 is now cruising happily.
Before, my Nexus 4 did not even detect my wifi N 5ghz AP while all my other devices could. The strange thing is my Nexus could see my neighbors' 5ghz APs but just not mine.

What Channel Width do you use? Auto/10/20/40 - at least these are the options in DD-WRT?
I still can't get my N4 to see my DD-WRT router's 5Ghz AP no matter what I try. I have since acquired an HTC One X+ phone and that has no problem seeing it, together with a bunch of other devices in the house, including a Chromebook. Something going on with the wifi chip and/or software in this LG N4.

Try 20mhz and a low channel like 40 or 48. Works perfect for me on dd-wrt

[Q] help wifi won't connect after upgrading to 4.3

Hello,
I'm hoping someone can suggest a fix, yesterday I upgraded to 4.3 using adb. I'm fully stock not rooted. today for some reason it won't connect to my home network. It's a cisco e2500 router and its on the 5ghz band. I tried setting different channels, turned off optimization....
what gives???

If i connect to the 2.4ghz band it works fine... wth

Seems like there is an issue with your router. Did you change anything recently in the router setting? Try restarting the router.

I had immediate problems with Wi-Fi after updating as well, I don't know what the new radio features but it turned out that a firmware update to my router had everything running smooth as butter again, actually better (a lot more reliable–YouTube app actually appears to buffer noticeably less and not break up, for example, downloads also initiate and complete more solidly) than it was under 4.2.2
ASUS RT-N66U

Nothing changed on the router i tried rebooting it also my Mac is still working fine

I have the same problem, since the update to 4.3 does not connect to the 5Ghz band.
I'm back to 4.2.2 and not connect, does it damage my hardware nexus 4?

I'm using an Asus AC66U at home and N66U at my office with no 5ghz connectivity issues.
Here's some things that might help you troubleshoot. Start by disabling the "avoid poor connections" feature in WiFi options. Install inssider or similar WiFi scanner to see if there is interference for your specific router config. Try removing the WiFi connection from your phone and reconfiguring.

Hi,
It's strange I have a similar problem. After upgrading to 4.3 my 5ghz connection came to a crawl. We are talking about 1.2-1.6 Mbps. But the 2.4 ghz was fine (35 Mpbs). Once I downgraded, re-writing the "radio" file, then the 5ghz connect was blazing fast again (50 Mbps). I'm convinced this has to do with the "radio" update, but I'm not sure what exactly.
Any suggestions? Currently I'm back on 4.2.2 as wifi speeds (PA rom) make more sense right now.
Thanks in advance!

I tried all of the above, every combination, reset my router, there are no other 5ghz overlapping networks, at this point it is something to do with my install. I wonder if a factory wipe would help...

That's my exact setup (E2500' did you set the Wi-Fi frequency band to 5GHz only on the N4 and give the band a different SSID from the 2.4 GHz network?)! Try forgetting the current connection and setting it up again.

I'm pretty sure it's not your router setup and the radio upgrade, as I mentioned earlier. Try going back to stock 4.2.2 and see if you can connect

If it were the radio software specifically, then logically 5ghz would be broken for everybody, which is not the case. Perhaps the issue is device data specific... There has to be a better solution than staying on 4.2.2.

I have with wifi problems too, but with 4.3 and 4.2.2 version. At home everything works fine, but at work phone connect to router, but no Internet (internet work only 1-2s). Other devises with this router works fine!

I have even a different issue. The phone is stuck at Obtaining IP Adress every time now. I downgraded to 4.2.2 and it's still doing the same thing. It does work if connected to a different router, but not to my main one. I haven't changed any router settings either.

5 ghz WiFi no Longer works 4.3?

I just setup a 5.0 ghz wifi router today. My nexus 4 doesn't seem to be able to connect to it now that I am running 4.3. I can see the ssid. I type in my password WPA2 and it reports saved under the network ssid. However no matter how many times I tap it, it never actually connects. I tried everything from restarting to flashing 4.3 again. Nothing helps.
I read several threads and reports about people experiencing slow speeds on 5 ghz after the 4.3 update but no one seems to mention not being able to connect at all. Some posts suggested that it works for them if they remove their router's password but I don't want to do that. I'm wondering if anyone has been able to use WPA2 and be on 4.3 successfully.
It's not a network or router issue. The router works perfectly with every other 5 ghz device that I have.

try changing the channel on the 5Ghz network, as some phones/tablets are quite fussy about what channel they work on!

This just started happening to me as well. I was away from my normal WiFi networks for a couple weeks and also updated to 4.3 and had to reboot the phone once or twice. Now I can't connect to any 5 GHz networks. I've tried 3 different networks that were all set up on my phone previously. I've tried "forgetting" them, turning off WiFi and then turning it back on, rebooting the phone, no difference.
On some networks, my phone doesn't see the 5 GHz band at all and on others it shows up until I try to connect; then it disappears.
Android 4.3 just seems to be another piss-poor update in a tremendous string of crappy software "upgrades" for me: Win8, Intel Centrino 6235, Google Maps, Hangouts. Quite the string of bad luck. It's like the world is telling me I need to buy Apple...

Drop the channel down to 36. All shall work then. This issue is in the note 2 and note 8

OP: changing channles fixed it for me..

Same boat. Tried low and high channels. It does see it. CM10.2.

In my case I do not see 5 ghz network at all. I set it to be on chanell 44 (20 Mhz), no security - still the same issue.
Also I realized, that even if in Wifi Advanced setting I set "5 ghz only" I still see 2.4 chanells.
I am running latest stock 4.3, no root.
4.2.2 same config worked ok.

5 GHz works fine for me. Do radio firmwares also effect Wi-Fi and Bluetooth?

I was having the issue. None of my devices were connecting. All on 4.3. But I rebooted the router and it's been all good since. It may have changed its channel though. It's set to auto channel. But all my devices connect no problem. Using 40mhz and n only since AC not supported on nexus 4.

What happening if you go to wifi settings , advanced and select Wifi Band - 5 ghz only ? Do you still see 2.4 AP's ? In my case, I do. In 4.2.2 I did not.

Interesting - as I am still get 2.4 AP's. I used a factory default images for JWR66Y to un-root and get full stock (only bootloader remains unlocked).
And even with full stock , un-rooted I got the same problem. I was using Purity ROM with Franco kernel before that - with the same problem.

I did some more tests, and I found that immediate after reboot, I can see my 5Ghz network AP, even connect to it.
However, after few hours it was inaccessible. Also, nerveless what I do, if I select to use only 5Ghz band I still see 2.4Ghz AP's. No idea why.

Both my N4 and my N7 (2013) won't connect to my router when it is using WPA encryption. My N10 is fine though. I have had to lower encryption on one frequency band to WEP - which I'd rather not do, but it is the only way I could get it to connect.
It seems sensitive to brands of router, as both devices connect to my work network fine and that also uses WPA encryption.
My home router is a TP-Link Archer C7.

Hi,
I have this issue logged with Google at the moment regarding the 5Ghz issue. They are fully aware of it and say numerous customers have been affected - their original solution to me was to downgrade to 4.2 and lose my warranty. When I said won't do that they offered RMA which 2 weeks later I'm still waiting for them to sort.
According to Google just because other devices work on 5Ghz doesn't mean the Nexus 4 will, so I can't how they can sell it stating it works with 5Ghz when it doesn't.
Also have post here
update: received my replacement phone on 21/09/13 and this is running 4.2.2 and connects to my 5Ghz without any issues - done a side-by-side video of the faulty phone running 4.3.3 and sent this to Google - I have told them it was working fine before update

[Q] Will 4.4 fix the 5GHz issues?

I have yet to be able to connect to any 5GHz network after 4.3, does anyone know if they addressed the issues in the 4.4 update?

Mine connects to 5Ghz on an AEBS without issue. What wifi are you using?

I have a Belkin N750 router and I have tried all the settings and channels on both 4.3 and now the official 4.4 still can't connect to the 5GHz network.

[Q] Lollipop 5ghz wifi

Hi all,
Is anyone having problems connecting to 5ghz bands on their N4?
I reconnected a simultaneous dual-band router that I used while my N4 was on KitKat. It would connect on the 5ghz band without issues, and I could view the 5ghz bands on inSSIDer. I installed the Lollipop factory image and now I cannot view or connect to my router over 5ghz, only 2.4ghz. Setting a different SSID, changing channels and widths does not help.

I'm having the same issue. It doesn't detect any 5 ghz wifi even if I set it to 5 ghz wifi only. I've flashed the factory image a second time thinking that might fix it but it doesn't.

I'm at work now where we have multiple 5ghz networks, and I can't see any of them. Any ideas on what I can do about this? Report a bug somewhere?

I have the the same problem. I've tried high number and low number channels on my Nighthawk using factory firmware default settings.

I solved the issue by reverting to kitkat 4.4.4. I think Google still has some work to do on 5.0.

i've the same problem.... i also thought to revert to KK but dont have the time for it....
i just wish google will fix the 5GHz issue and i wish for black theme (hate this bright white)

but i have one more problem with wifi. sometimes the phone can't reactivate the wifi module after i used bluetooth in the car. only restart helps

Yeah, I've been having the same issue since upgrading to lollipop.
I remember those issues with one of the older versions of android, but on 4.4.4 all was fine, I could see the networks and connect to them.
Now I no longer see any of the 5Ghz networks.

My nexus 4 (with Lollipop) behaves a bit differently. It does see 5GHz networks when set to 5GHz only, but doesn't see them in automatic mode.
