Hi everyone!
I used to have the issue of my iprowifi4965 chipset keep losing connection when using WPA2 encryption. Without WPA there were no problems. Julian’s addition to ifconfig in hrev50150 solved the issue for me (Thanks, Jua!).
I added the following to the “Tips” section of the wireless page of the user guide. Thought it may be of use to others, and since user guide export seems to be problematic for some time now… Here we go:
Avoiding connection loss
Haiku's drivers for some WLAN chipsets like the iprowifi4965 are prone to lose connection when using WPA encryption. If you're affected by that, try to disable the "HT mode" (high throughput, 802.11n) before connecting to a network:ifconfig /dev/net/iprowifi4965/0 -ht
If that fixes the problem, put that line into ~/config/settings/boot/UserBootscript to have it applied automatically every boot-up.
