I have a Cox cable 300MB plan and they convinced me to upgrade to a SURFboard SB6190 modem saying I would see 5x speeds of my current older modem. I had been seeing 120MB over my ethernet network. After upgrading the modem and rebooting modem and router a dozen times I am now seeing only 50MB through the enternet, although 300MB when connected directly to the modem. All speed tests are via Speedtest.net.
For testing purposes I disconnected all devices from the network except the one PC, so we are dealing with just the modem, router, and PC below:
MODEM
SURFboard SB6190 (32x8)
ROUTER
Linksys E3200
DD-wrt
PCs
Windows 7
I have swapped the cable between the router and modem a couple of times, but the old cable was getting 120MB so that doesn't seem to be the culprit, and I am using the same cable that achieves 300MB to the computer. Wi-fi speed is only about 25MB although the connection claims over 144MB to the router.
I have scoured this forum and the internet for solutions, but all problems are slightly different so no solutions apply. It seems like it must be a router setting, but I'm not sure how to begin troubleshooting. Any settings to check or strategy on troubleshooting would be greatly appreciated!
Thanks!
