So I just upgraded and am paying for 200 mbps and only receiving 25 or 90. My router is a 450Mbps Wireless N Router TL-WR940N. My modem is a ARRIS SURFboard SB6121. I have reset both multiple times and still no use. I'm using a ethernet cable and think it is a cat 5. I do a speed test with the ethernet cable and get 90 download and about 10 upload. When I switch to wireless I get 25 download and 10 upload. This is insane! I was previously paying for 30 mbps and had the same download for wireless. I have no idea what is wrong as my router and modem are capable of 200 mbps. Hopefully one of you can help me.
