CM1100 has speed lower than my internet provider confirmed

Question

(Firmware Version&nbsp;V2.01.02)&nbsp;Hello,&nbsp;I just bought the modem. The internet went smoothly; however, the speed is much slower than expected.My Xfinity provider confirmed with me that my download speed is 60 Mbps from their end. However, no matter how I tested (on both speedtest.com and&nbsp;http://speedtest.xfinity.com/), my speed is only about 18 Mbps.Before renting their own modem to see if I have a better result, I still want to try if there is a way to fix it myself.&nbsp;Thanks,&nbsp;

Try a different test PC. If the ISP confirms speeds are good up to the modem then check your PC and or connected external router if you have one connected. Directly connect a wired PC to the modem with out the router and speed test there. Ensure LAN cabling is of good working quality. CAT6 is recommended.&nbsp;

Nothing in the CM to set. LAG should be disabled is all. If you tested different PCs and such. I would presume the modem needs to be RMAd.&nbsp;vkdelta&nbsp;

you dont need LAG for 60 Mbps.. LAG is for &gt;1Gbps service.&nbsp;Have you tried testing DIRECTLY to the modem?What ethernet adapter do you use?
