Bridging wlan0/wlan1

[Dave]

I haven't tried your suggestion yet....but I see what you are getting at.
Using WDS wouldn't solve what I am trying to accomplish I don't believe,
because the radio on wlan0 will be performing two duties...receive from STA
and transmit down WDS which appears to be cutting the bandwidth in half. I
was trying to bridge the two radios so that when wlan0 is doing receive from
STA it is passing the packets to wlan1 for transmit to the other remote AP.

I noted Jacques reply and sort of understand that I cannot bridge across the
radios like I was thinking.

I am wondering ( and I will give it a try ), since you can bridge wlan0 to
an eth0 and that works, could I bridge wlan0 to eth0 in br0, then bridge
wlan1 to eth1 in br1, then bridge br0 and br1 together...or instead of using
eth0 and eth1 use a dummy interface maybe?

Anyway...when I have used WDS links in the past, I see the maximum bandwidth
at about 300Kbps however when using wlan0 bridged to an ethernet interface I
can see around 600Kbps or so. Is this normal operation?



Thanks!
