I have a wireless network whit 50 pc, antena 24dbi and senao as access points. my internet comes from a adsl router model LG 400c whit 2M of bandwitch, from there goes to a senao connected via wireless to an ethernet converter whit pcmcia Orinoco Gold, and comes down to a linux fedora core 5, that works as an router whit 2 ethernet conections, one to my 50 clients and the other is for the ethernet converter.

when there is traffic from 20 or more clients losses start goin up to 45% to 58%.

if ther is anyone who can help me, please... the 24 dbi antenas are ok, all the cable from the adsl to the linux machine are ok. also i have trayed whit an adsl router d-link 500g and have losses just in the router.. the internal network wass ok.. if some one could tell me what firmeware will go good on the d-link i will thank you soo match. the d-link just get down whit more traffic.

its probally just bandwidth saturation, as im sure you realise unlike ethernet which has independent wires all wireless traffic goes throught the same frequency/medium, If you have a lot of traffic then the background noise from all those stations is really goning to mess things up, and you'll experience lots of loss.

I would sugest using multiple (none overlapping) channels, and/or only use wireless where nessecary.
