Slow wireless network with Win98 and Dlink DWL510

Hi !
I've recently installed a wireless network with several
computers. Those with win2000 work fine, but one has win98
with a Dlink DWL510 wireless adapter, and network
performance is very low: has anybody already encountered
this phenomenon and found a solution ? Is Win2000 needed ?
Thanks.

parameter was too small. Thanks BBR !
