Ok so thanks for your Information
I found several good Linux roms for the mk802IIIS so i think i could get usb to lan to work. Maybe i´ll consider to build my own case and mod the antenna.
Yeah heat going trough the board isnt good, especially on the cheap PCB and solder they might use.
Ok qualalol, then i will give the usb to lan a try. Yeah my wireless modem is in the top floor, but im considering putting the mining rig in the cellar. Maybe i´ll use a extender if the lan adaptor fails.
Thanks, so if i get it, i´ll do a test and Review. If i got the same Problem, i´ll do some mods and post it back in here :-)
