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.

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.

Changing my AP's channel to 48 from 40 seemed to work for me. My Nexus 4 can now see my 5GHz AP.
Thanks!

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

wifi bands

Does the Nexus 4 have all the wifi bands... 802.11abgn or just the 802.11bgn?
I couldnt find an answer to this.
Hopefully someone who hasbhe device and also uses the a-band can chime in...
Thanks

It is abgn

Thanks mate.
It comes to me as a surprise because Google doesn't list 802.11a support for the Nexus 4 on the Play store specs.
Is 802.11a not officially supported by android? I ask because even in my Galaxy Nexus (and this is just couple a days ago with full wipe and installing 4.2.1 from the stock rom via adb), i initially tried to connect via my 5Ghz network but it just wouldn't connect for the life of me. 2.4Ghz worked like a champ.
EDIT: I should note that the problem with the 5Ghz band is only upon initial starts. If I disable and re-enable wife, 5Ghz works just fine, but I simply don't get why it fails on the first try.

802.11n also uses the 5Ghz band, or do you honestly mean 802.11a, that most ancient of wireless standards?

yes 802.11n "can" potentially use the 5Ghz "a" band if the 5Ghz "a" band is supported.
802.11n standard was designed to implement speed rates upto 450mbps (depending on the number of channels being bonded)
802.11n doesn't simply imply that it can use the 5ghz and 2.4ghz bands. it has to state that its 802.11abgn for me to be able to do "n"-speeds over 2.4ghz or 5ghz
google play store's specs show 802.11bgn which implies its only 2.4ghz.
if its 802.11abgn, then it works for me because i use the 5ghz exclusively to avoid the noise of all the 2.4ghz channels around me and theres a ton of them

WiFi / Bluetooth

From a system dump, it looks like Bluetooth and WiFi are via the very popular for 2014 Broadcom BCM4354.
http://www.broadcom.com/press/release.php?id=s827695
Key Features
The Broadcom BCM4354 is a dual-band combo chip for smartphones and tablets that supports 5G Wi-Fi 2x2 MIMO, Bluetooth (BT) 4.1/BLE, Rezence wireless charging support and FM radio receiver.

I doubt the FM antenna pin will be connected to the wired headset jack like the Nexus One (HTC Desire). But as my sig implies, I'd be very happy if so.

I was going to post actually, because at home I have both 5Ghz and 2.4Ghz SSIDs and the Nexus9 will not see the 5Ghz SSID.
Has anyone connected to a WiFi network on 5GHz with the Nexus 9 ?

It works on mine at 5GHz but I think it has to do with the limitation of the channels that the Nexus 9 will detect and connect to. Try using the lower channels like 36/44/48

Mine runs on my home 5ghz network and runs extremely well had zero issues.

So, once I changed the channel, everything was dandy !
However, one more question on Wi-Fi. Connect to a WiFi network that requires Sign-In doesn't appear to work on the Nexus 9. My Nexus 5 beside it, once I click on the notification, takes me to the web page to sign in.
The Nexus 9, takes me to a white screen with a Blue Header entitled 'Sign-in to network' and then does nothing
If I fire up Chrome manually, it takes me to the Sign-In page.

So this is another bug. I have this, too. Also, 802.1x Auth doesn't work with the N9.

Unstable wifi when using bluetooth

Hi
I have bug: when I'm using Bluetooth (connected to my miband 2) my wifi is randomly disconnecting. Is this normal? I'm on stock 7.0 eu phone.

It can be with some devices... BT and 2.4Ghz WiFi can interfere with each other since both run in the 2.4Ghz range. Change your router/AP's WiFi channel or connect at 5Ghz and the problem should go away.

That's what I thought since I had simmilar issuse with my tablet before. My router is 2,4Ghz only so maybe it's time to upgrade.

Just log into your router and set the WiFi channel to the highest number available (11 or 14 depending on region) and test... If it's not better try 1 or 6. Worth a shot.
Good luck.

Does the mini support AC wifi?

It seems that a simple file edit can enable 5ghz wifi, but can it support 802.11ac wifi as well? I need to know since we're planning to upgrade wifi routers sometime soon. Thanks.

Not according to gsmarena

After installing Lineage OS, I only saw 2.4 as the stock, but then installed WIFIman from Ubiqiti on google play and now i can connect to 5ghz!!
