I'm sorry if this has been covered before.  I have gone over all the 
archives and could not find reference to it.

My current setup:

WAP11(- - - - -)WET11===DWL-900AP+(- - - - -)Clients

I have a main antenna tower. It has about 5 clients connected to it.  I 
also have three "relays" connected to it.  The relay is a WET11 and a 
DWL-900AP+ connected together with a short ethernet patch cable.  This 
allows me to extend the wireless network out further and to get around 
trees and mountains.  The problem that I have is that the WAP11's seem 
to lock up all the time.  First I thought that I could build some type 
of timer to power cycle them every 10 hours.  But I'm not a electronics 

I do have a few old 300MHz system around.  What I'm thinking is to 
build a smart relay.  I put two Linksys WMP11 PCI cards into the Linux 
box.  I have one running in Master mode and the other running in 
Managed mode. I aim a parabolic antenna at my main antenna and an 
omnidirectional or sector antenna to the clients. I can ping the 
clients and the server from this relay.  But I can't ping from the 
client to the server or the server to the client.  I'm not doing 
NAT/MASQ.  I know that its a routing problem, but I'm not sure how to 
fix it.  I've tried to bridge the two wireless cards, but that does not 
work.  Maybe its a IP Tables forward rule or something.  I have been 
searching the net for an answer, but I can not find one.

Does anyone here know how I can solve this problem?
