I recently flashed my new TP-Link WDR3600 from the original firmware to the OpenWrt Attitude Adjustment 12.09. Everything is running fine and I am pretty happy with the upgrade but there is one thing that is bothering me for which I do not know whether it is a problem in the router or the firmware or something in between.
Every 30 or so minutes (it is not a regular interval) the connection to the router drops. Firstly, it was when I was connected via 10/100 ethernet on my iMac running OSX 10.9.2. I thought it might be some software issue and cleared PRAM etc but it continued to drop every now and then. Then I thought it might be something with my wiring and decided to move to Wi-Fi on the Mac but it is still happening. It lasts only 10-20 seconds until it reconnects but it is a bit annoying when you are trying to load a page and the moment you click on the link the connection drops.
On the last drop I got this from the log:
Mar 23 06:54:04 OpenWrt daemon.info hostapd: wlan0: STA 10:9a:dd:9f:46:80 IEEE 802.11: disconnected due to excessive missing ACKs
Mar 23 06:54:34 OpenWrt daemon.info hostapd: wlan0: STA 10:9a:dd:9f:46:80 IEEE 802.11: deauthenticated due to inactivity (timer DEAUTH/REMOVE)
I looks like it explains the disconnect but I am not sure whether this is only for the Wi-Fi or could explain the ethernet drops as well. I read about it and changed the disassoc_low_ack=1 to disassoc_low_ack=0 in the config file but as far as ethernet goes is there a setting for it as well?
