Speed drop from 200 to under 50

Hi There, 

Been having an issue with my Virgin speed in Area 21. For the past 2 weeks nearly my speed has dropped dramatically. I contacted the Virgin for help and we went through the steps of restarting PC/Router, factory resetting and monitoring. Speed did not increase so an engineer was booked for Mon 15th Oct as no fault in the area. 

On the day the engineer was coming out my speed went back up to 200 so I cancelled the engineer...How silly of me!

I have been away for a couple days and now my speed has dropped again. Have done all the same tests as before but to no avail. 

PC is running off Ethernet connection.

Below is the Downstream and error log from router. Upload is perfectly fine.

Re: Speed drop from 200 to under 50

Looks like an issue with the downstream signal to noise ratio on channels 15 & 16 right on border line, so looks like a tech visit is needed, can call faults and have rearranged or can wait a few days for forum admins to arrange

Hi icewolf250

Welcome to the community and I'm sorry to hear of the slow speeds you've been experiencing. I've run some checks on your connection and everything is looking great now. Are you still experiencing slow speeds? If so are you connected wireless or via ethernet?

Speak soon

Re: Speed drop from 200 to under 50

Hi There

I apologise for my late reply again. Things have been good with the speed since posting. I do get the occasional drop to lower speeds but I gather this is just throttling during busy times.

 

I do however think something is wrong with my Hub3. Quite often the RJ45 ports just stop working and appear to stop giving out DHCP. All wired devices therefore do not connect but phones on Wifi still work. Problem is only solved by rebooting router.  What are the chances/cost of a replacement?
