Lose 2.4ghz connection

[mrpink57]

Having an all of a sudden strange issue.

My 2.4ghz wireless is "turning off" when it only has one client that is not active. The 5ghz is what is mainly used in our house with a few clients connectiong to 2.4 (chromecast and 3DS) which is rarely used.

I saw this wifi issue and am not sure if this is what is effecting me, but when I view my logread I see a deauth from hostapd when this happens.

I am currently running a logread -f while at work to see what happens while I am away and can post that log when I get home.

My router is a 1900ac v1 running March 03 2017 Gargoyle-ispy, this was flashed from stock and I keep stock on the other parition.

Items I am using are:
DDNS
Tor
Samba
ACC QoS

For my wireless I am using N not AC and am using b+g for the 2.4ghz network. 5ghz is on channel 36 and 2.4ghz is on channel 6. We live an apartment in a dense urban area so the 2.4ghz is a mess when I view the spectrum analyzer.

I forgot to post a lot of follow up information on this. But so far I have pinpointed this to the guest wifi network.

I have this enabled as 2.4ghz only with WPA2 security and everytime I get home I see a bunch of deauths (4 way handshakes) on my logread. Once I disable this network everything seems to be working fine. I tried for the sake of testing putting my guest security at WPA and still getting deauth errors. I than tried via ssh/command line setting the security to wpa/wpa2 mixed and that disabled all wifi. As said before there is only one device connected that is mine to this network which is a 3DS. Every other device I own is on 5ghz network.

Any thoughts?

This is a question for Lantis

1900ac v1 and wifi drivers?

Is it a driver issue?

[mrpink57]

I am currently on your latest release April 01 2017.

Are there config files you want from me Lantis? I did not run a logread -f today, today I disabled guest wireless.

[Lantis]

Interestingly what you describe are the exact symptoms of a problem in early revisions of the driver.

If you'd like to share your config I'll take a look.
I don't think guest wireless should cause any problems but it might.

I am running my 2.4ghz network at b+g not sure if that 'NONE' means anything it has happened before in previous revisions of ispy to me. Everything else is untouched via command line just through the GUI.

[ispyisail]

Have you tired a factory/failsafe reset (or re-flash)

Its a bit like a windows reboot sometimes...........

[mrpink57]

A couple times I have along with a reflash. I keep stock firmware on part 1 and gargoyle on part 2. I do not think this issue happened with Feb 27th firmware which I have not tested since my gf would not be too excited with the internet down all the time while I swap firmwares. Also I do not restort firmwares, the only thing I keep is hosts and ethers and manually do the rest.

My last flash was on Monday to April 1st firmware. As far as a failsafe I am not sure how to do that on my 1900ac.

[Lantis]

NONE implies only b+g, that's ok.
I'd be interested to know if you experience the same when enable N

[mrpink57]

Previously I have experienced it with N enabled. This same exact issue happened with a WNDR3800 also so I am thinking it might be my settings more than just the 1900ac. I will swap to N thought to see what happens. I keep both at 20hz being in a big city.
