I am running on Windows Vista and out of no where I cannot connect to my network %70 of the time. When I can connect I have local access and a full bar signal but no Internet access. But when I have internet access every page takes forever to load (if it even loads). I tried reinstalling my drivers and even hanged some registry stuff. So any help will be appreciated. My wireless card 8.11g by Broadcom.
 

It is the family network so 3 other devices are connected. I have a desktop.
 

How do I change the channel on my router?
