Okay. This is two problems rolled into one basically.
First of all, my computer suddenly disconnected itself from the wireless network and couldn't reconnect. I looked and the wireless adapter is missing from adapter settings and I couldn't find it in device manager either.
Windows troubleshooter had no help and I can't really re-install the drivers since I don't have internet on that computer.
I would connect it up to ethernet, however the router is far too far away. Any ideas for fixing either of these would be appreciated.
