Since about Thursday my internet speeds have been periodically dropping to 0.05 Mbps (ping and upload are unaffected) at random intervals and remains low until I reboot. Rebooting the router usually fixes the issue but it inevitably happens again.

I did contact tech support and worked through some troubleshooting. They suspected it was a bad coaxial cable but due to covid a tech would be unable to rewire until measures are relaxed.

After the call I tested each coaxial in my house same issue after several hours it would drop. I changed the splitter same issue, I removed the splitter and connected directly to the cable coming into my house. I thought attaching the modem to the line directly had fixed the issue since it was stable for about 8 hours but then the speeds dropped again.

Just not really sure what else to do, as far as I can tell it's either a bad modem or the line coming into my house.

Has anyone experienced similar issues? What was your fix?
