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

Wi-Fi: 802.11 a/b/g/n (2.4/5 GHz)

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

So i have a week old galaxy S4 and everything is fine until i realise that it only sees and connects to my 2.4Ghz SSID. I use a dual-band sitecom WL-309 extreme gaming router. My laptop, ipad and galaxy tab can scan and connect to the 5Ghz SSID. I'm really surprised that a phone that boasts 802.11ac isn't even able to see 5ghz wifi. i recently installed the wifi analyzer app, and it doesn't help, can only still see 2.4.
I recently upgraded my firmware to the indian MEA stock ROM. Dunno if anyone out there has experienced this, help apprectiated.
Thanks
I saw in a post that wifi channel may be the problem, my router has the following 5ghz channel options: auto,36,40,44 and 48. Just tried all and still no joy.
im having the same problem exaclly.
i cant see any 5Ghz network at all.
i tried replacing channels on my router and still. cant see.
Hello everybody,
I have searched all over the web and these forums trying to find an answer as to why my Galaxy S4 (SGH-M919)refuses to connect to my wifi network using wireless N (802.11n).
I thought something was wrong with my network at first, but I went into service mode on my S4 and clicked on wifi and it says this:
Link Speed: 5Mbps 802.11b
Now, when I'm in service mode looking at that, I click the option to turn off WIFI Power Save Mode. When I turn that off, it refreshes and connects to 802.11n at 54Mbps, but that only lasts for 2 seconds and then it reverts back to 802.11b at 5Mbps. GAH!!!!
My router is set to wireless N only, so I don't understand why my phone insists on using 802.11b instead of 802.11n. My router is an ASUS RT-AC68U and I am not a noob when it comes to networking and routers but I cannot figure this out no matter what I try.
My S4 works perfectly fine on 802.11ac (very fast) but that's only on the 5GHz spectrum and I want to use 2.4GHz for better range and other various reasons.
My router is awesome and very fast, and my S4 did the same thing with my old router. So it's definitely my phone. Any help would be GREATLY appreciated!!! Thanks in advance.

What makes you only have to use 802.11n?

Something is odd about what you are saying. If your router is set so only the N radio is active, what "B" wireless network is it attaching to? Not yours, surely.
You do realize that "N", although rated faster, does not have the range or general flexibility of good old "G" right?
And that's another question, why is your phone going to a "B" connection, and not a "G" one...
I recently upgraded to a new 802.11ac router.
All my other ac equipped devices work well in the full dual-band mode. But not the Note4. It doesn't want to use the two bands together, with the full added bandwidth.
The Note4 is supposed to be ac compatible, but mine will only use one band or the other. In normal use it only locks onto the 2.4GHz channel.
If I switch off the router's 2.4GHz channel, the Note4 locks onto the 5GHz channel straight away, no problem. And of course it has more bandwidth.
But as soon as I turn the 2.4GHz signal back on again, the Note4 goes back to the 2.4GHz channel only.
This happens regardless of the phone being close to the router with big signals on both bands, or further away with weaker signals.
I've tried using the 'Smart Network Switch on and off, but that seems to make no difference.
Any ideas?
Edited to say: The channels I'm using are both clear of interference, checked with inSSIDer.
Thats strange, i know its 802.11 AC. Thats a fact. But i never checked to see if its dual band compatible. gotta look into this, thx for the heads up...
I’ve got a very strange problem with my LG G6.
I have always been able to detect and connect to all wifi, including 5GHz, from any router. Recently I’ve noticed that my G6 cannot detect the 5GHz from a certain router we have in our home. It can detect 5GHz from any other router (in or out of the house), and it detects the 2.4GHz from the said router, but it cannot detect the 5GHz from the said router. Everyone else in the family can detect and connect to the 5GHz of the said router. I’m the only one who can’t. I’ve rebooted the phone and router many times. Tried different channels and settings. Nada. Can anyone please shed some light on this dilemma?
can you connect to other 5 Ghz networks?
Are you on stock ROM?

Yes. Like I said, I can detect and connect to all the other 5GHz routers that I come across. Only this one I can't. Yet everyone else can detect and connect to it. I'm the only one who can't and I'm totally baffled. I'm running stock ROM updated to Android 9 long ago.
In case of a missing or unregistered sim card the phone supports only channels 36-48, otherwise the national channel range.
At least half of all routers are missing the DFS feature and support only channels 36-48,which is fine in this case. I wouldn't want to own one of these.
I your sim card is a local network provider's and not a foreign one in roaming mode, things get more complicated, but it should be a matter of localization.
