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.

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.

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 issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?

still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength

I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

My n4 will not connect to any of the WPA2 AP's around here.

I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.

So this n4 is picky about. Certain WiFi networks.configs

Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.

Set lease time for as long as possible, it normally this is 2 weeks..

can you test to flash back CWM recovery and test again the wifi ?

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.

I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

5.0 5Ghz Wifi Issues

Did a full image wipe/install with the official 5.0. I'm no-longer able to connect to my Netgear r6800v2 router with the same channel 48 setting for 5Ghz that previously worked on android 4.4.4.
Any other folks out there with android 5.0 problems using 5Ghz channel?
EDIT: I should add - I'm fully aware the N10 has limited 5Ghz frequencies it works on (e.g. 40, 44, 48) - I've tried 36, 40, 44, and 48... none of these seem to work in android 5.0 with the same router settings. It can see the broadcast and attempts to connect, but IP address is never acquired (DHCP)

I'm having the same issue and my 2.4 network is very slow. Anyone else have this issue or any idea how to fix it.

Yeah I've had issues with 5ghz on every lollipop device I have. Haven't figured out how to fix it yet

I had the same issue and changing to Channel 44 (with Auto bandwidth = 40 mhz) solved it for me, it was on 36 initially

No problems here, did a clean flash of Lollipop and 5GHz is working fine with my RT-AC68U, channel 36, auto bandwidth.

Same problem here. Changed to channel 44 and is at least working

Wiped. Clean flash. No problems. On channel 157. Wish it would tell me if im 300mbit or not. Ac n66u.

Installed from a sideloaded OTA.
Have issues connecting to my Virgin Superhub 2 both on 2.4Ghz and 5Ghz.. Channel 8 and 36 i believe.

Go into Settings -> Wifi then tap the connected wifi network. It will tell you your link speed there. Mine is connected at 300mb/s, while in powersaver mode it drops to 24mb/s.

I've similar issue, but both on 5ghz and 2.4ghz.
The connection isn't stable and I get disconnected all the time after upgrading to lollipop. If I'm tethering with my phone right next to the tablet (on 5ghz) it works perfectly. I'm not sure if they've tweaked the disconnect/reconnect threshold base on signal strength.

I'm having problems with 2.4 Ghz wifi too. In Jelly Bean I have a pretty good coverage with my home router but with Lollipop I get lots of disconnections and slow speed. I'm not sure if it's a drivers problem or an operative system change, but I know for sure that it's a pain in the ass.

I'm having the same problem with 2.4 Ghz.

Both 5 and 2.4 are much worse for me as well compared to kk.

I've solved my Wi-Fi speed problems changing one setting in my router: just disable WMM ( Wifi MultiMedia).
Try to enable/disable that setting (can be shown also as WME instead of WMM).
Good luck!

My 2.4g is working perfectly, but it cannot see my neighbours 5g network. My Note 2 sees it fine. I checked with Wifi analyzer app.

I can connect to my BT home hub 5 but it only works for a free minutes and then it kind of freezes.
I'm still connected according to my tablet with good signal strength but there is no internet activity making the tablet pretty much a big paper weight for me at the moment.
If some one can help me fix this issue id be very grateful

Connecting just fine at 5GHz 300Mbps with 5.0. I have tested 2.4GHz as well and both function just fine.

I do connect easly, but connection quality is poor... There is definitely something wrong with Wi-Fi on lollipop

[Q] 802.11AC and 5GHz Issue

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.

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.

Strange 5GHz problem with G6

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.
