Modem resets, packet loss, high ping
Hello all,
Little bit of history to this:
- We had some mild connection issues in the last few years, but nothing spectacular.
- About two months ago, a construction worker cut our (and our neighbour's) connection from the street to the house.
- We were reconnected the following day by a Virgin tech.
- Following that, our connection was horrible - constant cut-outs, modem resets, bad ping spikes, packet loss, etc.
- We had another Virgin tech come over to check everything. The tech found that the signal at the modem was absolutely abysmal and found a -20db attenuator hidden behind a piece of furniture. It was removed and the tech declared problem solved.
- We however still experience numerous sync losses throughout the day with the modem ranging (5 or 6 times yesterday) due to T3 timeouts. We still have persistent connection issues.
I ran a ping continuously during my working hours for a while:
217512 packets transmitted, 216539 packets received, 1% packet loss
round-trip min/avg/max/stddev = 20.327/144.534/168586.567/2731.208 ms
We're a household of two, with me working online full-time and my partner part-time. I haven't had a single meeting where my connection didn't falter for months. I assume we need another tech visit, but I wanted to check if someone here in the Community may know a quick fix.
