Couple months ago i had an engineer around who managed to fix my issue with the lag spikes, However about 1 week ago my connection completely dropped for around 2 hours, Ever since then i've had the same constant lag spikes and packet loss return.

Yup that packet loss on your BQM isn't looking so good.

Power levels on downstream are a little too far apart.

6.8 vs 2.2. 

4.6 difference isn't the end of the world, but it could do with adjustment.

Post RS errors are too high.

I say it's either a network fault or a problem with the cable itself.

Can you check the coax cable it tightly plugged in to the hub, and any other connectors along the line.

Then give it a reboot to be safe.

The rest of the levels look ok to be honnest.

Thanks for your post on our Community Forums Livana

I've ran through a quick flow on your connection and can see that we'll need to have an engineer sent out to your property to have this resolved

I'll drop you a private message so you can confirm your home address and we can have this arranged for you

Kindest regards,

David_Bn
