"Something" is interfering with my cable modem and causing it to reboot. All the wire to the telephone pole has been replaced. The modem has been replaced. I had cable service here with no trouble. A month ago, 15 cable trucks descended upon my neighborhood, they said to "Clean things up." After three weeks, they left and left me with an inop connection.
"Something" between the time of 7:54 and 9:54 is causing constant reboots, then after 10:00 am, thing smooth out so I "only" get a reboot every hour or so. Sometimes it exactly on the nose, on the :30's or the :15's. Other times, it will be fine for 2 hours, then reboot.
When I say "reboot" I mean the cable light goes out while the power and PC lights stay on, then the cable light slowly flashes, then rapidly flashes, then comes on solid.
Once I saw a pattern, I started using Ping Plotter, to keep track. It is easier than hand logging.
My house is simple. I have nothing on timers, not even a VCR. After 3 truck rolls and numerous tests when nothing is wrong, there is no fix. All the wire and the modem has been replaced. They suggest that maybe a pool pump is to blame? I don't have a pool.
So today, I ring all the doorbells and ask about their pool pumps. One of my next-door neighbors has a pump that comes on a 7 am and shuts off at 12 pm, but all the others have other times. I turn off the neighbors pump, go home and look to see no fix.
I was able to get a SNR reading from my modem, but I can't keep it up since the cable company won't allow SNMP. I have to fiddle like crazy to see what I have.
Here are the numbers I can get: Power Level: Received: 4.4 dBmV Transmitted 41.6 sBmV Received SNR: 32.5 db
Sorry, but that's all the Toshiba PCX2500 will let me see.
I am open to ideas.
