PacketLoss on M650 (UOmph)

[recalluk]

For the last few days I have started to get packet loss on my connection. Its fairly new (1 yr) FTTP connection and up until now had been flawless.

I started back on @27th and then stopped but seems to have returned on the 4th. Although not huge it very noticeable on Voip when working from home and gaming.

Speed tests seem to indicate issue is on the upstream side as then it kicks in upload halves.

Ookla reports between 2 and 5% loss and BQM is also showing it :

Hi there @recalluk 

Thank you so much for your post and I am so sorry to see you have had these issues with your connection! 

I'm very glad to hear it now appears to be back to normal, but are you able to monitor this for us over the next few days just to make sure? Should there be any further issues I'd be more than happy to take a look again for you! 

Thank you
