Nokia Lumia 1520 802.11ac 5GHz wifi issues

[Morpheus Phreak]

I am such an *****. I sat down and did further testing that that seems to be the issue. The hidden SSID thing appears to have been a red herring. I guess normal people rarely turn off their cellular unless they are on a plane so they wouldn't have an issue. I only turned it off for testing purposes. Funny thing is if I never tested it there never would have been a problem!

A little bit of google turned up a couple of things that leads me to believe ac requires two antennas. I am no networking expert so don't quote me on that. But it does make sense. Thanks for all your help.

Higher spectrum and speed networks do require both antennas on.

I hadn't realized you were trying to access them with something disabled.

I'm trying to connect to Aztech 7003 with my 1520 but it couldn't proceed with the 5GHz. No problem with 2.4GHz.

Im using the TP Link Archer C7 ac router, but my lumia 1520 cannot detect (doesn't display) the ac band. I've tried resetting my phone, and reconfiguring my wifi, but it still wouldn't work.

On my Lumia 1020 it only works using the lower 5GHzchannels ( I use 40 for now ). Otherwise I am unable to find the networks.

Hello, Same here with TPLink Archer D2 and Lumia930, the phone doesn't see the 5GHz frequ.

if someone still needs answer or others also may consider my answer. I use 1520 and it didn't connect as AC, but when I gave different SSID for AC and N then I was able to connect AC.

A Google search brought me to this thread because I too have been having issues connecting my 1520 to the 5GHz band on my new 11ac capable router - a Fritz!Box 7490.

Even connecting to the 2.4GHZ was unreliable - failed connection attempts outnumbered the successful by a ratio of around 5:1. Even the successful connections would often drop out after mere seconds.

I tried the various suggestions presented in this thread - all but one with a rather frustrating lack of success. Grrrrrr....

The final thing I attempted was to do as dravik suggested in his post of 04-20-2015; and that was to configure the router to use lower channels. Although he was speaking of the 5GHz band, I applied the change to both the 2.4GHz and 5GHz bands.

Lo and Behold!!! All my problems were solved. It has been a week since I made that simplest of changes on my router and the 1520 is now connecting, and re-connecting automatically, absolutely, perfectly, reliably to the 5GHz band every time it comes into range.
