Slower Broadband Speed

Joining in


I am currently on the Virgin M200 (now M250 with the recent upgrade), Maxit TV and Talk weekends and evening package until May 2020.

I have only been getting a maximum of 150Mbps for the last 2 weeks and any point of the day.

I have the Virgin Hub 4.0 which is set to Modem mode and connects to a UDM Pro via Ethernet Cat 6a. I have done numerous power recycles on the Hub and UDM Pro with no effect. Interesting, the Hub keeps saying it needs a reboot (pulsing red light at top of hub) after first reboot but connects on second reboot...

I have even put the Virgin Hub back in router mode with no difference in speed. I did speak to someone on Virgin webchat who confirmed I am on the M250 package and not being throttled. Virgin own Diagnotics shows no issue either.

I have not changed any of my setup in any way, so assume something down the chain at Virgin's ends has limited me to 150Mbps. When 200Mbps was working, I could get as high as 215Mbps when testing speed. I never go above 150Mbps at the mo..

Anyone have any suggestions that suggest I am missing something or can someone from Virgin shed some light on the matter and solve it.

I have been offered a great deal by Sky as my road was recently upgraded tto FTTH and I am tempted at the moment, but still on contract!

Solved it!

I had Jumbo Frames turned on in the UDM Pro. Turned that off and all working great now! 

Thought I would leave this here for anyone else that has a similar issue.
