can the tp powerline run wireless and cable at the same time
You can plug both in at the same time and be connected to both, but you can only use the Internet from one of them. The computer will prefer the cable. So if you only have Internet access via one of them then yes you can be connected to both networks.But if both are capable of providing Internet access, then Ubuntu will prefer the cable (Ethernet) network to access the Internet (and not use the Wifi network to access the Internet). have a laptop, can i use Wifi and cable net at same time? from the title of the question. NO you can't use them at the same time. @rinzwind â Alvar Jan 16 '12 at 15:43.
