My wife was given a Thinkpad T410 (refurb). It came installed with windows 7 pro and qualifies for windows 10 upgrade which I tried to do twice. And twice I had to roll back to 7 because I lost connectivity via my wireless network and don't know why or how. Evidently this Thinkpad uses Bluetooth to connect via my WiFi passphrase but loses Bluetooth which windows 10 does not support and upon upgrading advises that Bluetooth has been removed or otherwise deactivated. Thinking something had to be updated or configured in device manager under network adapters I see iNTEL ® 82577LM GIGABIT NETWORK CONNECTION and INTEL ® CENTRINO ® ADVANCED-N6200AGN. I attempted to update the drivers for those but M$oft says they are already the latest. So maybe they don't work for non Bluetooth WiFi???
I have tried to connect using the same WiFi process that works for three other computers (windows 10 & XP) on my network but always get a "not connected" or otherwise offline message, so I'm guessing that whatever this Thinkpad has installed for wireless adapters does not work or is invalid for WiFi wireless connection. Very strange because anyone else in my family can WiFi connect with their puters or devices if in range of my network when they're visiting me.
Wondering if I have to buy a laptop wireless adapter for this Thinkpad or else just forget windows 10 upgrade and stay with windows 7 pro on this Thinkpad laptop. Only reason I would like windows 10 is it's faster for certain purposes.
Any ideas, solutions, suggestions, anyone?
