I have a wired connection: leased Arris WMB760a, Vonage adapter and desktop PC. My tier is Blast 50/10.
Saturday was connection issues day from hades. Mid-morning walked by desktop to see a Windows error message on the screen along the lines of "TCP settings incompatible with router". Don't have a router other than what's built-in the Vonage adapter. Speed test showed I was getting 49/17kbps !!! Another speed test had NO upload speed. Couldn't even get google or yahoo to load. Tried to use phone but fast busy.
Cleared cache/cookies, power cycled everything; restarted PC. Same error. Called Vonage. Fast busy due to poor connection. In the meantime, lots of T3 errors in log. Also noticed my downstream signals were varying from 0.xx to 4.xx.
Tried direction connection sans Vonage: no joy. Sometimes I'd get 50/4; othertimes, that lovely 17kbps for upload. Called Comcast and (luckily) got a rep who listened. During the call, the issues cleared up. An hour later, same thing but cleared up and (knock on wood) have cleared up.
Why would that TCP message pop up as I didn't dabble with anything and - while my cats are smart - they only chew the ethernet cables. Would it be anything to do with IPv6 of which I know diddly ?
Any ideas/help, please ?? Thanks very much in advance.
My log shows the CMTS MAC addy as CHANGING on 12/4/2014 ??? Log attached.
