I have a CGM4140COM modem and I'm currently hard wired from the modem to the desktop.
(I have not added the wireless router yet to show it's not the issue.)
As soon as I enable bridge mode my download speeds from from over 950 to below 500 on a consistent basis.
When I disable bridge mode, reboot the modem my download speeds are still below 500.
I have to factory reset the modem, set it up again for my 950 plus download speeds to come back.
I had the modem replaced about 3 weeks ago and I'm having the same problem.
Has anyone seen this type of behavior before?
I also confirmed with Comcast that my account is GIG speeds and I have used multiple speed test sites including Comcast's, Speedtest.net and Fast.com.
