Today I was using my sp3 to test a clients network and its WiFi speed. I ran the test and I couldn't get over 1 Mb download. I checked other PC's on the network and they were 8+ Mb. When I got home I checked my sp3 WiFi speed and I still was only getting 1 Mb download. I checked my other home PC's and they were 18+ Mb. I decided to go into device manager and uninstall the network card and then scan for changes to reinstall it. Now the WiFi speed is back to normal. Anyone experience this?
