We have the same issue with the Compaq Presario CQ62. RTL 8191SE - wifi
Safe Mode with networking seems to be more stable but still wouldnt be useable.
all drivers tried with XP with no joy.
Have rang HP twice got the phone put down on me twice :doh:
What to do next?
I've changed my SSID to TKIP encryption and it works fine, seems they struggle with AES (which is rubbish as I need AES!). Still, at least it works until tosh get back to me...
I've since changed the wireless mode on the laptops to B/G only, and they now work flawlessly with the AES encryption. still waiting on toshiba to get back to me, but at least everything works for now!
This driver should work for WPA2 AES.
Have you tried these: Ensure Wireless channels are 11 or below. disable WMM.
I had yes, Toshiba confirmed it was a problem with the released version of the Realtek driver, this one works.
