Re: [AR] Outages, slowdowns and question about UPS usage.

said by signcarver:

I think the no surge suppressor thing was generally for the cable itself as some can block or interfere with signals but if you have no problems using it (compared to not using it) I would probably want to err on the side of protecting my equipment vs an occasional packet loss as the 2nd doesn't cost me money but I'm out $100 if the modem is fried.

Yeah, he was talking solely about running the power through surge protectors and UPSes. I had mine hooked up to a decent size APC UPS and I'm going to switch it back. I never run RF through them.

I swapped out the modem to a Cisco DPC3010 and both modems are now seeing about 1% packet loss that happens in bursts of 3-4 lost packets every 12-15 minutes or so, which equates to 3-4 seconds of lost connectivity.

Both modems display the same issue with about the same frequency, though with the Cisco I get better signal and I'm bonding 5 channels instead of 4. Guess I'll have to set up yet another service call.

Here's the Cisco's signal info:
