This started a few days ago. Nothing in the network has changed.... I have a Motorola SB6121 modem, a Linksys WRT54G router (v5 with updated firmware), 2 computers on wireless and my computer wired. I get a C/D on pingtest with an occasional F or B; but almost never any packet loss. I reset all my networking appliances but that didn't help much at all. Are there are tests I can do completely reassure myself that the problem is on RCN's end and not mine? I did a few "ping www.google.com" (etc) tests in command prompt and in about one out of 2/3 tests, there was a ping spike that tripled or quadrupled (ex: 40,38,159,52). So I'm really sure the problem is with RCN. I called twice and they "sent" a signal to my modem but nothing happened in the end.
Well, the problem was gone this morning, but it's now back. I'm going to assume this is a peak-hour problem for RCN? Horrible ping all Saturday and Sunday, and 6pm onwards on Monday (today).
All this started about the time I noticed I had the "Mach 20" upgrade. So I pay more involuntarily, sure, I get faster internet, but that means nothing to me since I was completely content with 15mb/s with my old standard pings.... Did they physically change something with the upgrade? Or put more homes on a single "distribution"?
