So I've been having issues with latency to my first hop. Initially, I assumed it was linked to issues I have had with my previous consumer-grade modem which was flaky in other ways. However, I have since replaced my entire home infrastructure with a pfsense appliance and ubiquiti wireless (overdue upgrades). I am using transparent bridging on my dsl modem. I also have upgraded my speed to 20mbps last week so I was sent a c1000z to compliment the rest of the new infrastructure. The issues went away for a few days (which was also normal with my previous setup, the issues would come and go) but now I am intermittently getting 400+ms pings to my first hop after my home router like I did before. Note that these pings are being done from the router device itself, so wireless is not a part of the equation. My throughput as shown by speedtests seems to be somewhat affected but not badly, although netflix seems to have issues. (18mbps shown during "normal" ping times and 15-16 during the times of latency)
pfsense shows no outward issues, and seems to be routing traffic perfectly normally with miniscule cpu usage, memory, states table, etc.
I talked on the phone to a supervisor, and they are sending me a c1000a modem to replace the c1000z I got last week.
What really gets me is I am having the exact same symptoms on an entirely new infrastructure. It's just not passing the sniff test as far as the modem being at fault. It's possible it's a coincidence, I suppose.
The tech did some "tests" that hit my firewall with a bunch of strange traffic from qwest/centurylink's network which was blocked by my firewall - I didn't feel comfortable adding an any/any rule but I did allow icmp through which the tech was able to confirm the high latency.
Just wondering if anyone else has experienced something like this, or what I can do to help the "troubleshooting process" go faster. I now have to wait until tuesday when the new modem arrives before I'd expect any further troubleshooting to be done on my line.
