Hello, I have 30/8 mbps internet when I plug in via lan, but when I speed test wirelessly, I get 6.5/5. My router is downstairs, and I am upstairs, about 30 feet linear distance.
Wireless N, channel 6 (i have tried many channels, seems to be no difference)
Channel width 20mhz
Transmit Power 78mW (92% signal strength)
Encryption: WPA2 Personal AES
Otherwise all the advanced options are default
Please advise, thank you.
