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)

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

I've researched for any past issues on this topic but couldn't find anything similar.
I live in London and use Asus AC68U, I have connected my Note 4 (N910C) and Tab S fine on both 2.4GHz and 5GHz, but never checked whether this is connected on N or AC. The Channel setting on the router is left on Auto, and I've labaled the 5GHz SSID to have a "5G" at the end (eg. 2.4GHz SSID: "My WiFi" ; 5GHz SSID: "My WiFi 5G")
Then flew to Indonesia bringing along the AC68U, reset and reconfigured the Router to be used there, I have also configured an N66U as an Access Point (not repeater). Now my Note 4 cant' even see 5GHz anymore, even though wireless configuration is exactly the same as in London (except the WiFi SSID and password). I then found out a way to know which 802.11 speed my phone is connected to (by doing the #*0011# thing), and turned out it's on 802.11N 2.4Ghz.
I then went to the N66U (out of Radio range of the AC68U) and I still cannot see the 5GHz SSID. So I took out my Tab S 8.4, switched WiFi on, lo behold, 5Ghz is visible and able to connect to both router seamlessly. Checking the connection type, the Tab S is on 802.11AC Ch. 36 Frequency 5180Mhz, WiFi Power Save Mode On, link speed 866Mbps, to the AC68U.
My Dad has a Galaxy S5, it also cannot see the 5GHz SSID, but is at least connected to the 2.4GHz 802.11AC.
I have changed channels manually on the router but still can't see 5GHz from the Note 4, also switched OFF the WiFi Power Save Mode.
So the question is.... does my Note 4 N910C even have AC? And what is going on with my 5GHz band? Has anyone seen this problem before or point me to a thread you've been to?
I've got the n910c and connects in ac on 5ghz fine. I have a netgear r7000 running ddwrt. Has it ever worked for you ?

I also have the 910F and a Netgear R6300 with DD-WRT.
It took some configuring. But i expect this has something to do with the preset ups for using your router in Indonesia.
itll probably;y work when you get back to wherever you live.
Thanks for the replies.

5Ghz has worked for me in London using the same Asus router that I used in London, but I'm not sure if my Note 4 ever connected as AC.

Well, I brought the AC68U I used in London to Indonesia, the phone was connected on 5GHz on this router when it was in London, but somehow it can't even see the 5GHz SSID now in Indonesia.
I think I need to reset the modem and WiFi module somehow, been searching the web on how to do that but haven't found it yet.
Other devices that are currently able to connect to 5GHz and/or AC:
Galaxy Tab S: Can connect to 2.4GHz + 5GHz on AC
Galaxy S5: Can connect to 2.4GHz AC (Cannot see 5GHz AC)
Laptops: Can connect to 2.4GHz + 5GHZ N
Added Info: Tried WiFi Analyzer, Note 4 still cannot see 5GHz signal while the Tab S can.
Did you put in a local SIM? The phones may be respecting local regulations regarding frequency usage that the other devices don't, as they don't have a SIM giving them locale. I'd be curious what would happen if you put in your London SIM.

Yeah I'm using local SIM, but when I arrived still with my Voda UK SIM in the phone, the existing N66U Router (before I turned it into Access Point) was transmitting both 2.4GHz and 5GHz, my Note 4 couldn't see it. I thought I had switched off 5G SSID but when I checked, it was ON. Very sure something is up with this Note 4.
I removed the SIM card and inserted it to my LTE Tab S, switched it on, switched WiFi on, connected to 5G just fine.
I'm gonna try re-flashing the same stock ROM. This phone and the Tab are all Non-Rooted btw.
Solution: Don't set the frequency to "Auto". Manually choose the frequency for 5 Ghz, preferably to something low such as channel 36. This worked for me. I haven't tried with any other frequency though. Someone mentioned online that it might be due to Android phones not supporting DFS frequencies.
Good luck.

I just installed dd-wrt on my netgear r7000 and my n910h stopped seeing the 5Ghz band after that.
With r7000 stock firmware everything is fine.
Could you please tell me what's your dd-wrt settings for the 5Ghz band?
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...
Don't know if this has been asked but I've seen different things saying this phone supports 802.11 ac WiFi. Is this true? Interested in getting this phone if it does. Also like that it supposedly supports WiFi calling on T-Mobile, though I'm currently trying mint Sim which is the same network.
I think Nokia 6 using Dual Band AC WiFi with 5GHz support! Download apps call Aida64 then tap on network and find out.
Wouldn't I need the phone to use that app to find out? I'm asking anyone here on the forum if they can confirm that the phone can connect to 802.11ac. I ask because I got faster speeds from ISP and a new router to support speeds, but looking to get this phone if it can connect to an 802.11ac network.

If U have wireless router with 5GHz AC support try to disable 2.4GHz. If Ur phone support 8.02.11ac U will see that WiFi name
Unfortunately my phone doesn't support 802.11ac so I can't see. Currently using a Blu phone (the Life One X2). Is anyone able to confirm that the Nokia 6 does? Mostly asking cause I'm looking to upgrade to a phone that does and the Nokia 6 fits the bill along with the storage size it has
yes it does, i set up 2 network and it can see 2.4 and 5
No, it does not. It supports 802.11n 5Ghz, but not 802.11ac
The Nokia 6 (2017) contains a Snapdragon 430 processor...and Qualcomm's specifications for the Snapdragon 430 do mention integrated 1x1 802.11ac Wi-Fi.
@qwertysmerty Do you have this phone and have you tested that it does not support 802.11ac?
For context, the specifications for the newer Nokia 6.1 (2018) originally indicated that it did not support 802.11ac either — although it actually does (confirmed by testing). The specifications were recently corrected on Nokia's website.
Yes, I have TA-1025. I tried to connect to 802.11ac access points having channel bandwidth 80/160 Mhz with no luck. It discovered those AC access points, but could not complete association. But that was on 7.1.2, I can retest tomorrow with 8.1. Even if it supports 1x1 802.11ac that support is rudimentary.
Btw, specs for 2017 model on Nokia website still says just WiFi without specifying protocols:
Connectivity Micro USB (USB 2.0), USB OTG, Wi-Fi, Bluetooth 4.1

So I ran more tests today on 8.1.0 (patch level July 1, 2018) and got my phone connected to an access point running [email protected], channel 132, bw 80Mhz (80 MHz is definitely AC). So I'm taking my words back that Nokia 6 (2017) does not support 802.11ac. Probably there was an issue in 7.1.2, I recollect that in July 2017 there were numerous accounts when Nokia 6 wifi radio could not connect to certain channels even for 2.4GHz networks, wonder if it was the case for 802.11ac as well.
To be clear off the bad, its not the router. Every other device in the house that connects to the 5ghz band works flawlessly. This is a brand new international phone being use with AT&T in the US, calls and texts function fine. Phone is fully updated and so is the router.
Wifi however is only picks up 2.4ghz bands. Not 5ghz.
Wifi analyzers pick up 2.4ghz but when switching to 5ghz I get a messages stating my phone does not support 5ghz. Anyone else with this issue?
@aq3e No. It doesn't have 5GHz.
2.4GHz has better penetration through walls anyway.
5GHz is really only good if you're in the same room.

The A20 does support dual band, but it's disabled. I tried to enable it by replacing the mx140_wlan.hcf file located at /vendor/etc/wifi/ with the one from the A30 and it worked, but there's a problem.
For some reason the signal range is terrible, to detect a 5 GHz network the phone needs to be next to the router, if it gets some centimeters away the signal drops at the point where the network is not detected anymore.

5ghz wifi is certainly not only good in the same room, check online heatmaps of 2.4 vs 5ghz to compare, it's not a huge difference. Given how much less interference you will get on the 5ghz it often works a lot better than 2.4ghz even at longer ranges. Fix peoples internet for a living and I've seen thousands of peoples speeds double or even triple from changing to 5ghz even when router is on the first floor and they use it on the second.

(I know this doesn't help much with the OP's question but to dispel hearsay I felt it needed to be said.)
I know you don't know me, but I said I resolve peoples internet problems for a living both on supplier and consumer side and have tested this with thousands of customers but you trust a random article with very little info more and don't even bother to look at heat maps? This article has been made by someone who read a blurb about wifi, but they did get one thing right...
"A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality."
That list is very short, it also includes lots of computer peripherals, security cameras, smart home devices, walkie talkies, radios, remote controls, wireless handsets (landlines, not mobiles) basically every wireless device you can think of uses 2.4ghz and even your microwave! all these devices on a long range signal means your neighbours devices also overlap to combine together to make the 2.4ghz band for most consumers a disaster for anything requiring more than slow speeds. This goes without even mentioning that the 2.4 ghz band only has 13 channels (3 none overlapping) to spread every wifi device out on to stop interference, in most residential are this is simply not enough. In many cases this is so bad that even next to the router people can lose 80 - 90% of their speeds or have so much interference that even loading webpages takes a long time due to the amount of data being lost.
Like I said before, even if the 5ghz DOES have shorter range, it is not so short that you have to be in the same room, what would be the point? That is a something people assume because it's a "shorter range signal" but it's not that short! the 5ghz is usually faster due to it's naturally higher data rates and more consistent due to the lack of interference from intermittent signals. Most things that interfere with 5ghz are constant and therefore it's much easier to test and know what speed you can get in other rooms away from the router, unlike the 2.4 which has the same issues with passing through anything only with a load of other issues on top too!. The 5ghz also has the advantage of having over 100 wifi channels to spread networks out on to avoid them interfering with each other, a vast upgrade to the 2.4ghz.
Here is an example of a heatmap comparing 2.4 and 5ghz but just looking at any article that goes beyond a very brief description will show you why the 2.4ghz is often so much worse than the 5ghz.
What's the Difference Between 2.4 and 5 GHz WiFi?
What do these numbers actually mean? Does it realy matter? Is one better than the other? How many questions are we going to ask in this description?
socialwifi.com
2ldr - It depends on your house and nearby networks, test both bands with different devices in different rooms and compare speeds, outside of doing more thorough testing with other apps and equipment this is the easiest and quickest way to see which will work better.
You have 2 choises use BT modem BT modem Plan A: one Device in 5GHz network one device sharing Internet from BT modem feature. +Advance use Open Garden mesh client for better Internet throught BT modem. Construction of my plan:One or two devices in 5GHz WiFi network and 3 devices creating PAN network trought Bluetooth.if Your Bluetooth version is 5.0 you can use Mesh network profile. than using Mesh network structure.

Do it again in the following order maybe ?
1. Download both mx140_wlan.hcf and mx140.bin from the git I gave you above.
2. Turn your wifi off.
3. Reach /vendor/etc/wifi folder using your favorite file browser ( Mine is Mixplorer ).
4. Overwrite both files.
5. Reboot your device.
6. Turn Wifi back on.
7. Do a Wifi speed test ( Wi-Fi Sweetspots app for me ).

I use a Magisk Module instead of directly overwriting the files, but this should make no difference. I believe it may be a hardware difference between our devices. On the schematics the 5GHz antenna seems to be marked as optional, maybe that has something to do.
I tried to put my device next to the router, and when I did it the network got detected (with bad signal tough), I could connect and the download speed oscillated between ~50-200 mbps (my network has 300 mbps). Once I moved further from it, the WiFi disconnected as the signal was lost.
