i have just upgraded to 2.9.1 on all of my routerboards.
In rc9 there already was a bug-fix called “fixed wireless WPA with WinXP”.

has anybody got some expiriences about that.
i can not connect wireless to a 2,4Ghz Hotspot using wpa tkip with a windows xp sp2 laptop.

at first i used wpa-aes … but this did not work with my standard clients: wpa-supplicant:

What’s new in 2.9rc9:

) added support for BCM5721 Gig-E cards;
) improved wireless frame handling;
) fixed wireless WPA with WinXP;*
*) fixed wireless wds-slave bug;
*) lot of other wireless bugs fixed;
*) fixed bug - AES group key handshake failed;

there was still small issues with WPA that we fixed. Please send the support output file support@mikrotik.com after you tried to connect using WPA.

so i tried again… and made a supour.rif from my accesspoint … thats a rb500 with 2.9.1
and a supout.rif from the pppoe server thats also 2.9.1. but thats a computer…

supout → rb500 with hotspotantenna.http://www.hostalka.com/supout-hotspot.rif
supout → computer pppoe server http://www.hostalka.com/supout-pppoe.rif
