The dropoffs in speed you see in the following graphs appear to be gradual, but the reality is that they’re immediate cable modem disconnects. These graphs are from a bandwidth/speed graph plugin used inside the Deluge bittorrent client under Linux (Ubuntu Gutsy), by the way. Not that the OS or software matters. It could be Windows, uTorrent, FTP, SFTP, WinSCP, large ISO http download, whatever.
The bittorrent software takes some time to tidy up packets from the various download sources, making the dropoffs to zero-speed look gradual, when they’re really not gradual at all. So don’t think they’re gentle disconnects, because they’re not.
The first graph below depicts a typical cable modem (CM) drop/reboot and dead connection with some dead connection time (30 seconds or so), followed by a completed reboot with a live connection that lasted all of about 20 seconds before it dropped/rebooted again.
During a heavy downloading session, this can happen dozens of times an hour.
More examples of CM reboots follow below.
I’ll add that while I’m paying for "premium" 15Mbps down/1Mbps up service I’ve not noticed better than 10Mbps down since this started. And even when I get that kind of speed, it’s never for very long before everything reboots. When I’m downloading something larger, several reboots in succession confuse my router (two different routers, in fact: a Linksys WRT54G (running either stock Linksys firmware or alternative DD-WRT firmware, take your pick) and an older Netgear wired router). This usually ends in a router WAN IP renew needing done, or a router reboot, or a complete router reset (losing all settings).
This situation actually FUBAR’ed my Linksys router last year, but I was able to bring it back from the dead several months later doing a number of warranty-voiding things to it not for the faint of heart; most people would have tossed that $80 router in the trash and bought a new one, even though the router’s malfunction wasn’t their fault, at all.
Is this kind of constantly-unstable connection worth $50-60 bucks a month to you?
I really just want is the problem fixed. However, it would certainly be nice and proper to receive some remuneration from Time-Warner Milwaukee/Roadrunner for all the lost time and hassle, too, both for the current ongoing situation, as well as this same thing when it happened last year and went on for most of a year’s time. Given the lack of response when this happened last year, I suspect nothing will be done again this year.
How many other Milwaukee-area customers, or Roadrunner customers in general out there, have this problem?
It seems entirely possible it’s not your fault.
