It seems if you run a Vostro (like me) Windows 7 might not be your friend if you want your touchpad and video card to work.

Or maybe they will fix it in the next week, but I doubt it.

The problems with the downloads cutting out your VoIP connections can easily be solved with QoS. Over at LinksysInfo.org You can find the latest news on linksys devices, including the firmware updates from Sveasoft with QoS implementation. If you run your own firewall you can find easy solutions to setting up QoS just by searching google.

I have QoS set up on my iptables firewall on Linux which I only had to add a few lines for. It allows me to make VoIP calls without any interruption.

I will probably be switching to broadvoice as soon as they have porting set up so that I can take my home phone number to VoIP. I believe that within the next few weeks they are supposed to be ready to start porting.
