Hi,
I am using Shorewall shell on my Linux router. Basically the router
has 2 interfaces; ppp0 for wan , br0 for lan.
Under br0 bridge interface I have ath0 (wifi atheros) and eth2 interfaces.
I have no performance problem on the lan clients which are connected
to eth2, but for the clients connected to ath0 wifi interface there is
a big performance issue.
When there is no traffic on wifi interface, the client can ping the
router with 2ms response. But when the client starts any web browsing
or any oher traffic, the ping responses from the router go above
1000ms or even 2000ms.
Of course data communication from the wifi clients are terribly slow.
The client seems to be connected with 54Mbps but it can''t go even up to
100kbps.
It first seemed to be a trafffic shaping problem to me , so I moved
all tcrules, tcclasses and tcdevices files and restarted without any
traffic shaping. But that didn''t solve the issue.
How can I troubleshoot this ?
Below is some information from my linux router. I will send the
shorewall dump output in a seperate email.

Ok; then there is a driver issue , unless any hardware failure ? I''ll submit a ticket to the Madwifi project group. Do you have any information about Madwifi and mini-pci Atheros cards ? What may have cause such failure ? (like unplugged antenna ?)

Thanks for your help. Just one more question before closing this. You are sure that this is not anyhow related with Shorewall or iptables, right ? It''s about driver or hardware for certain ? Thanks.

Shorwall/iptables can''t cause that. The error rates on the physical device are the *first* thing you should look at when you have performance issues on traffic through a particular interface. - You have not mentioned your wifi interface anywhere in the Shorewall configuration. How then could Shorewall/iptables be causing performance problems on that interface and not on eth2 (the other port on the bridge)?
