I've done some bandwidth testing on our wide area (several km from
STAs to AP) and got surprised with hostap vs wlan-ng diff. results (both
STAs with hostap managed mode on WL200 cards).
STAs are Pentiums 166/200 with linux-2.4.20 and hostap (with one STA switching
to wlan-ng yesterday).
Detailed setup & results (netperf -fK output into rrdtool graph) are at
In short: from about 10~15 Kbytes/sec with hostap to 35~40 Kbytes/sec with
I suspect that hostap card resets on Prism2 (apparently _not_ the case with 2.5)
are killing TCP throughput ...
Is there anything that can be done (eg. debugging) to help hostap driver dev. ?
Thanks for the great hostap driver, Jouni...
