Here is my problem:
I have a DSL-2730U ADSL Modem/Router and just bought two D-link DWA-548 Wireless N300 PCI Express Desktop Adapters. my problem is that one of my Wi-Fi Adapters is far away and when i try to connect it doesn't connect to internet.it connects to modem but it gives me a limited connection(without internet). but when i bring it to the same room as Modem I have Internet connectivity.so distance makes internet unavailable.
here's my question: if I upgrade my modem to a better one like TP-LINK TD-W8968 or D-link DSL-2740U will it fix my problem?
