B8 High Latency and packet loss

I'm experiencing constant packet loss and high latency. I'm finding it very difficult to work from home.

Re: B8 High Latency and packet loss

Umm, we will need a few more deatils to help you...like I dunno...anything?

How are you connecting to your HUB? How are measuring packet loss?

Next-

Go to 192.168.0.1 in your browser, or 192.168.100.1 if in modem mode

 

Do NOT LOG IN

Post your upstream, downstream and network metrics from your HUB.

Screen captures are nice, C&P will do though.

 

Someone will get a look for you.

Re: B8 High Latency and packet loss

It's been weeks like this, can't get through service services by phone and ignored on this forum.

This is todays result.

The last 24hrs...Luckily my contract is ending in a month, I'm definitely not renewing, might even end it early.
