My laptop randomly drops connection to the internet. I'm running Windows 7 Home Premium 64-bit. I've just upgraded from Windows Vista Home Premium 32-bit. My laptop doesn't lose connection to my network, just the internet. I'm not sure how to describe or what really is wrong :(
EDIT: seems that it was a problem with my wireless router, changed that it hasn't lost connection since, thanks for all the help.
devmgmt.msc
then press enter. Then click the small arrow next to "Network Adapters". What is listed in that section?
