I have a TP-Link AP and configured it as follows:
Max Tx Rate 300Mbits
Security WPA2 AES
However on my S4 I get only 65Mbits
On my ISPs modem/router (Arris) I have the same setup with Channel 6 and I get 75Mbits.
Even if I get very close to the device, the bandwidth won't change. I know I can't get the 300Mbits but I cannot understand why I can't get at least the same 75 that I get with the Arris device or even at least higher than the 75.
