Sorry Microsoft but after being nagged to upgrade to Windows 10 for a long time I finally do it and instantly I regret doing it. I have a Dell Alienware laptop working fine but now I have no wifi and none of the suggested resolutions work.
I now know why you are giving away free upgrades - we are your test monkeys for your garbage update.
There are too many instances logged about this for it to be a driver issue so stop trying to blame everyone else and fix your ****. Maybe next time test it properly before you release it.
Very unhappy.
