Having trouble solving this issue. Laptop gets kicked off wifi on regular basis. Only way to reconnect is reboot. Laptop was replaced with identical laptop from sony. Updated to latest wifi drivers. Power settings for everything are set to always be on. Changed channel for wireless. Replaced access points with another brand. Put in a new USB wireless from a different manufacturer. Updated BIOS. No other computers at this house are having issues. I cannot find any setting anywhere that is causing this. Everything seems to point to the laptop but I cannot for the life of me find what on the laptop is causing this.
