so, you think that 20~75 mb/s (depends on wifi interference and Access-point quality) is more slow than 15 mb/s theoretical max on N-WiFi over 5 Ghz ?

just installed "7260.HMWG" and patched bios. Windows 10 pick-up new WiFi card without any word and she working from the start without any driver installation requirements

Worked like a charm with one note, "fix for error104" were needed for me, everything else done without any problem. For the part of creating bootable dos usb - more simpler to use "Rufus" with included FreeDOS, rather than HP util and looking for the dos system files.

this could be any miniATX like Zotac, with possibility to add any feature you want

Why not use wifi range extender?

simplest thing is to use Teamcity, but this give to you only remote desktop view. To access network you need to understand how to tune DDNS (in case of dynamic ip) and vpn

try to fully remove and reinstall the drivers. Possibly after remove, best thing to do is to use some "cleaner app"

did you tried to switch SLI mode and use nvidia auto-tuning for the games after?
