why is there packet loss

[boltedenergy]

Experiencing intermittent drops and upstream packet loss on a daily basis. Example below:

Tested from wired clients, so not sure if this is a line or a router issue?

Reboot the router and post a fresh set of stats after a few hours. You need to post all the information btw.

Just going on the information you have posted there are far too many T3 errors.

Hello @boltedenergy,

Welcome back! Thanks for posting.

I am sorry to see that your broadband is not working properly.

I was unable to locate an account for you, has your service improved since you posted this? If not let me know.

Many thanks,

[boltedenergy]

it seems to have stabilized for now.

Is it worth doing a daily router reboot?

It shouldn't be necessary.  Post the stats again after a couple of days.

How do these look?

Still far too many T3 errors in a short period. 

[boltedenergy]

So is there anything I can do about T3 errors?

Insist on a technician visit to repair your connection.
