Poor performance when using WDS with a Senao NL-3054CB3 802.11g repeater

It's almost like you are dropping down to .b speed (11 Mbit). In
theory g is 5 x times faster than b and if you get half the
performance by repeating it should be 10 times slower - which is what
you are getting!
Remember that if you have any b gear on the network it will often all
drop down to that speed....
