I would recommend TP Link specifically the WDR3600 it is dual band (not AC) and has 2 usb ports on it. The reviews on this router are pretty decent as well along with the price tag being under $50.
What you mean by "usb router"? Do you need a router with USB port for storage? If so, you cannot find one for under $50.
I meant to a mobile router so i can find more networks in far more distances .
The problem is that where i live ther're networks that requires a pass , and i know there is a way to break the passwords .. so here you have another question .
I can invest more than 50$ so the reception distance will be be .
can someone explain me what i need to know about Wireless USB Routers ?
