The bandwidth test sites mentioned offer a decent method of testing 
Internet connection performance. As mentioned, other network traffic 
will interfere with your results so I'd recommend you average out 
several tests over a few days (and at different times). I do this when 
testing changes to my firewall/router. I'm not really interested in 
maximum speeds just the average.

Comcast, my ISP, advertises 8Mbps down but I typically see 6Mbps down 
(and 390kbps up). I intend to call them to make sure I'm receiving their 
"fastest" service as they've added speed tiers to their Internet 
offering. (long after I was a subscriber)

As for synchronization et cetera. I have a Motorola SB5100 from Comcast. 
It's diagnostic interface is accessible by pointing a web browser to 
192.168.100.1. The only relevant information I can see from these web 
pages includes signal-to-noise, power level and error logs. Google your 
make/model cable modem for information on how to access it's diagnostic 
info.
