Hello OpenWRT Community,
i´m sitting here, after a few days working on the problem, drinking sherry.
I have a WDS system with 3 nodes up and running (stable) and decided to give you some of the help back that you gave me.
Here it my setup:
WRT54GL <---------> WRT54G v.3.1<----------> WRT54GL
300m 350m
So, i wanted to supply three households with both a AP and a bridge to my internet connection (the WRT54G). Everything with WPA encryption. Here is some stuff i found out, besides reading the documentation:
- There is a WDS_timeout nvram variable. Set it to 0 to stop your WDS system to crash every few hours.
- If you want to use WPA, don´t use TKIP. Use AES. I don´t now why, but with TKIP, you get packet loss, disrupted connections and burning cats falling from the sky.
- Set your SSID broadcast to on (wl0_closed=0). I somewhat helps stability.
- Don´t try afterburner. Waste of time. At least in my case. ^^
- My central device has both the macs of the other two in the "wl0_wds" variable. The other both, despite being in range of each other, only have the one of the central (the WRT54G).
- "wifi" can revitalise dead connections. So i wrote a script to use with cron:
The PINGIPS variable is to be set to the IPs of things (e.g. the next AP) that can be reached if the connections stands. If they come through, nothing happens. If not, "wifi" is run. Additionaly the output from "date" is saved under "/jffs/wlancheck.log" so you can see the time of the last run. If you uncomment the line with "echo ...", the script produces an output, which IPs couldn´t be pinged.
#!/bin/ash
PINGIPS="192.168.1.251 192.168.1.252"
for IP in $PINGIPS; do
if [ `ping -c 1 $IP | wc -l | cut -c "7"` != "6" ]; then
# echo "I run wifi for $IP now"
wifi
date > /jffs/wlancheck.log
fi
doneThats that. Here is my complete output from "nvram show | sort":
