Hourly disconnection problems with SB5100?
For a couple of weeks now I've been having a very weird problem: every hour, at the same time (:30 minutes past the hour for example) the net will go down for 30 seconds up to 20 minutes. The SB5100 shows no errors, the router (a 3Com 3CR860-95) shows no errors, the net will just be inaccessible. I've been running PingPlotter to plot the outages.
Now, I have found that rebooting the router will usually solve the problem for a couple hours, but since the problem occurs at EXACTLY the same time, regardless of when I reboot the router, I've been informed that it's likely not the cause. I have isolated specific PCs on the router and the problem remains. Generally, rebooting the modem has no effect.
The outages seem spaced by about 60 minutes and 10 seconds - what was originally happening at :30 minutes past the hour a while ago has slowly and very evenly worked its way up to :45 minutes past the hour.
I'm on Rogers in Ontario and the problem SEEMS to have been reported by at least one or two other users (
Anyone have any suggestions? What occurs once an hour like that? Here's the current modem stats:
Downstream Value Frequency 615000000 Hz Locked Signal to Noise Ratio 37 dB Power Level -5 dB The Downstream Power Level reading is a snapshot taken at the time this page was requested. Please Reload/Refresh this Page for a new reading
Upstream Value Channel ID 1 Frequency 32496000 Hz Ranged Power Level 36 dBmV
(I seem to recall that the downstream power level used to be more around the
0/+1 dB level)- Sunfox
