Internet connection dropping, noticed DHCP renewall

RadDudesman — Wed, 20 Mar 2024 10:51:27 GMT

We keep losing our internet connection only briefly but long enough for teams/google calls to drop, streaming to buffer and other issues.

I've see the following post and noticed I'm having a similar issue. Does anyone know a resolution?

@RadDudesman

There is nothing wrong with your log, renewing the lease on your public IP is a normal process.

Can you please post your router stats

Thansk for getting back to me, I agree that DHCP renewall is a normal process however these events always seem to coniside with my connection dropping...

Below is a screenshot of the router stats as requested

@RadDudesman

Yea so no drop on the LAN for the last 34hrs and line conditions are perfect.

When did you last notice an issue?

RadDudesman — Thu, 21 Mar 2024 15:58:05 GMT

Today has been good... Yesterday and the few days before have been terrible with repeated connection drops even on equipment directly cabled in to the router

@RadDudesman
Be useful if you could post your stats again on a day where you have repeated drops
