Router: Asus rt ac68u
Build: DD-WRT v3.0-r40270M kongac (07/11/19)

Nothing but Wireless connectivity issues since updating to this build. Before anyone asks, yes - I did a factory reset. At first it was the 2.4ghz band that seemed to stall and disconnect intermittently. Then the 5ghz band started dropping regularly. I checked the logs and consistently saw this message:

Code:

ct 22 15:48:00 DD-WRT user.info : nas : daemon successfully stopped
Oct 22 15:48:02 DD-WRT user.info : nas : NAS daemon successfully stopped
Oct 22 15:48:05 DD-WRT user.info : nas : start nas lan
Oct 22 15:48:05 DD-WRT user.info : nas : start nas for wl0
Oct 22 15:48:05 DD-WRT user.info : nas : NAS lan (wl0 interface) successfully started
Oct 22 15:48:05 DD-WRT user.info : nas : start nas for wl0.1
Oct 22 15:48:05 DD-WRT user.info : nas : NAS lan (wl0.1 interface) successfully started
Oct 22 15:48:05 DD-WRT user.info : nas : start nas lan
Oct 22 15:48:05 DD-WRT user.info : nas : start nas for wl1
Oct 22 15:48:05 DD-WRT user.info : nas : NAS lan (wl1 interface) successfully started


It’s usually preceded by what appear to be normal system messages (rebind attacks devices joining the network, etc) but I can post more logs if needed. Every WiFi drop is associated with the NAS message. So, I tried “stopservice nas”. Now my 5ghz is gone, and my 2.4ghz is stable.

What the heck... I’m just leaving the 2.4 up and not rebooting because finally SOMETHING is finally stable.

I just want stabile WiFi! This is my 3rd DD-WRT update to the system, and this is the final build (afaik Kong is no longer doing builds) and each build has increased in stability issues on this router. Can’t say I’m gonna keep it, lol. Buy another router and/or switching to tomato or brainslayer seems to be the only solution.

Anyway, help would be appreciated. I’ve really customized my LAN and would really hate to have to start all over again.

Hi!

I have the same router, same problems.

I'm on BS build DD-WRT v3.0-r40900 std (09/04/19), so I don't think you'll find a different result by switching over.

From your log's mention of wlan0.1, I guess you have a 2.4 virtual wlan like I do (guest network, probably?) and I think that might be related to our problems. For me, this device is the router so it's important to have the guest network be there and not on a different device on the open LAN, but I can put my 5GHz main network on a normal non-isolated device. So I just plugged a different device into a LAN port and broadcast my 5GHz from there. Not elegant, but the best I could manage.

So, I don't have a fix to suggest, but I can corroborate what you're seeing.
