[Madwifi-users] High Errors in WDS Mode

[Mike L. <nas...@co...>]

hello,

I have two systems setup as WDS Bridges according to the "Alternate 
Option" on http://madwifi.org/wiki/UserDocs/WDSBridge
It is working and I can pass data back and forth from LAN1 to LAN2. 
However I am not getting very good throughput.

I ran " /usr/local/bin/athstats -" on both machines. I am getting many 
crcerrs and phyerrs.
Is this indicative of bad hardware? bad antennae? driver?

It looks like most of the phy errors are OFDM timing errors.

I am using a subversion checkout of -r1725
Should I go with a later revision?
