Hello everybody,
I'm experiencing a strange behavior with DD-WRT on Linksys E900. The wifi randomly freezes for a couple of minutes and then resumes by itself.
The config is pretty standard - DHCP for WAN, WPA2-Personal for the Wi-Fi and a couple of clients peaking 5-10 Mbit/s in total.
If I connect to the LAN port instead of using WiFi I have a stable internet connection. Resetting the wifi like
Code:
wl down
wl radio off
wl restart
wl radio on
wl up
is fixing the issue without physically re-starting the router, but I don't like it. I'm trying to dig the cause and patch it without 'hacks' like a magic cronjob task executing the above code when some check fail.
Please suggest from where shall I begin. What I have done so far:
1. Disabled the SPI firewall, QoS and pretty much everything loading the router.
2. Checked the /var/log/messages and the latest entries around the time of the failure are

it was K3X. Thanks for the heads-up, upgraded to: v3.0-r36698 mega ( 08/22/18 ) which is the latest version for E900 according to the router database, and will get back here in case that the issue continues.

Wonder if anything would change in 37012 (the actual latest build posted here: https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2018/ ), but hmm. The only wi-fi issue I am aware of revolves around the GTK rekey interval, which I've set that to 0 and most of the problems are resolved... although, every now and then a disconnect and reconnect of wi-fi clients seems to fix things.
I've changed the CTS Protection Mode from Auto to Disabled and for the last couple of hours there are no issues. In case that the issue appears again, I'll test out the beta.
