I'm not sure whether this is a Power Pack 1 Beta problem or not! All works fine over 'wired' LAN connection but usually will not connect (occasionally VERY slow response) over Wireless LAN. Same symptons on three client machines with different WLAN adaptors. LAN shows at 100 MB/s and WLAN at 54 (occasionally 48) MB/s. In all three cases the WLAN works 'normally' with standard Internet access. Is this Power Pack 1 or a conflict with the latest batch of 32 bit Vista updates installed on the same day?
I've not (yet) submitted a bug report with all the CAB files etc. but will do so if someone can confirm that I'm not completely bonkers!
