I have sony vaio VPCSB36FN model. My ethernet as well as wifi adapters have stopped working at the same time. I did not update or roll back drivers before it stopped working. They were working just fine until i tried restoring media gallery from sony vaio care after an update of the same didnt work. It restored media gallery but i could not open. And at same time adapters stopped working.
I tried reinstalling the drivers for the adapters whose specifications are Intel centrino advanced N-6230 (for wireless ) and realtec PCIe GBE family controller (for ethernet) however, that did not resolve my problem.
I updated the drivers, still same problem. The device manager does not show cross or exclamation mark on these adapters. The trouble shooter for windows cannot solve issue just says "there may be problem with drivers of wireless network adapter " and similarly for LAN adapter. "ipconfig" command in cmd promt does not list any adapters at all.
I have dual boot (Win 7 and Win 10) and the drivers and adapters work fine with windows 10 (Minor size partition) and win 7 as major partition.
Please let me know if there is a solution to this problem. Or whether i must format and reinstall windows again.(which i don't desire).
