Certainly is a head scratcher indeed, best thing to do after checking all this with no success would be to have a different laptop and side by side when it starts to go iffy and check that ones status, if both show issues then it's the wifi/ISP but if one is fine and other is borked then it's computer issue (somewhere)
well i have this computer wired up to the same router and network and i never experience any of these issues!
