Hello,
I have this Asus notebook and a small TP LINK router with battery and sim card that belong to a friend of mine who does not know much about computers.
The comuper detects the small router but there is no connection to the Internet.
The router is a TP LINK M5350 but the same problem occurs withy a TP LINK M5250.
It seems strange to me that the two small routers should be defective.
I tried many options but I cannot get the router working.
With my personal router, a TP LINK connected to the mains, there is no problem.
I cannot access TP LINK page for the small router because the page detects my personal router and not my friend's.
Can anyone help?
Thanks and regards
