hi! Windows pushed and update to my computer (64bit Vista Home Premium) on June 13th. After this update, the computer can no longer connect to my wifi. Other devices are connecting so it is not the router. There are no backups before the 13th so I can not restore to a previous date. I have reset Internet Explorer to default setting, reset the router settings, and run a full system scan with my Norton AntiVirus. All of these did not fix the problem. Any advice would be appreciated!
