Hi darkangelic
Quoting your post above "
Re: cable modem t25
Depending on the modem firmware installed, the second ethernet port can be used as a second IP node (as per above) or as a Link Aggregation Port (coupled with a compatible router or computer).
If you attempt to use both ports without configuring them properly you will get connection errors on one or both of them. "
I purchased a T25 and have been having intermittent disconnects. Took it back and got a replacement. No change. Arris says they need Upstream power of +45 to +51 but both the T25s show in the +30 range. The Xfinity tech says his meter shows 5 db greater than the T25 and also says the +45 to +51 range is not achievable.
Could the configuration issues you mention be the issue? I'm using both ports on the T25. Xfinity told me I could use both because IPs are dynamically allocated (I'm beyond my competance to know what this means). How do I 'configure the ports properly'?
Thanks
P. S. The Xfinity tech installed a test modem yesterday and plugged my desktop into one of the ports and my Linksys WiFi Router into the second (of 4) port.
