Disconnected, router log errors

Problem started this morning: no internet.

Powered down/up router, online briefly, then dropped again.

Reset router, back online.

Disconnected later on, router had green light, no phone line. Couldn't connect via wifi to router. Finally it started working after another router reset.

Called 150, no issues in my area, no issues found with my wifi or router. Told it might be network instability, should settle in a couple of days. That's too long to be missing online meetings, can anybody help please.

Re: Disconnected, router log errors

Your stats don't look ideal, but it could just be something or someone messing about in a local cabinet. I'd give it a few days to settle.

Re: Disconnected, router log errors

Thanks for your prompt answer! A bit hard to "wait and see" when meetings depend on this, but I'll trust your experience.

Re: Disconnected, router log errors

Do you know, if your snr was that low before today?

Sorry, I didn't look at this data before today. (I had issues with slow speed, but never disconnections.)

Re: Disconnected, router log errors

Okay. It can also work with a lowish snr, but a history could have told us, if something major happened today. 🙂

Re: Disconnected, router log errors

Some days, my SNR drops through the floor and I get massive post rs errors and constant drops. Other days are perfect. Since I can't put my finger on what the problem could be and it's not a permanent fault, it can't be easily fixed. Somebody messing with the cabinet could easily cause those faults. 

However, since if I don't have internet I don't get paid as I can't do my job, I have multiple internet connections. When one goes down I use the other. It's a small price to pay to ensure I get paid.

Re: Disconnected, router log errors

That is sound advice, and I will look into backup options.

Just weird that this started today. Like I said, no disconnections before...

Thank you!
