Re: [Madwifi-users] ack-timeout (transmission acceptance timeout)

[iwik <iw...@iw...>]

Hello,
there still wasn't ansewer to this Dave's question. It's very important 
thing, becase now madwifi can't be used at longer distances. Our 
experiences are, that on about 1 mile distance, speed is only 90-140 
Kbyes/s (measured using ftp). And that's very bad.
When we can expect some working solution ?

Thanks,

Ivan
