I may have solved my A6210 Windows 10 incompatibility by uninstalling old WG111 drivers

i upgraded from Win 7 to WIn 10.

My A6210 caused Windows 10 to crash upon attempting to log in.

I tried many fixes, the one that FINALLY worked for me was uninstalling the A6210 drivers AND the Mediatek alternative ones I'd tried AND some WG111 drivers that were still on my machine (with lots of reboots after each change) Followed by downloading the latest A6210 drivers (v1.0.0.34) and installing the "-SA" drivers only installer. These then worked without even needing a reboot.

My advice is that if you have tried all the other solutions on this forum and it still doesn't work for you, consider looking for old Netgear drivers still lying around.
