Constant iplayer buffering and huge lag spikes when gaming

500 Mbit service. Desktop PC connected via ethernet.

For weeks, now, I've been suffering a LOT of buffering with BBC iplayer so that it's unwatchable.

Coupled with that, I frequently have huge lag spikes while gaming. My games freeze for 10+ seconds at a time. It's less frequent than the iplayer buffering but still extremely detrimental to my competitive gaming experience.

Speedtest shows good speeds ~550 / 35 


The tests and service status procedures show nothing wrong, as do the tests done by people on the end of 150 phone calls, but something is most certainly amiss here.

There are many Critical

No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;


and Warning 

Lost MDD Timeout;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;


messages in the network log of my hub3.

Things were better, although never perfect, when I had the 350 Mbit package.

Power cycles and hard reset using the pinhole on the hub3 do not help.
Tweaked or tuned NIC settings and even default NIC settings do not help.
Even tried a brand new clean Windows install. Didn't help.
Alternate NIC didn't help.
Port forwarding for the games I play doesn't help (also never been necessary before).
Hub3 in router mode or in modem mode with a 3rd party router, doesn't matter.
Entirely different PC. Nope, still iplayer buffering.

Help, please.

Re: Constant iplayer buffering and huge lag spikes when gaming

Hmm - odd - the power levels and SNR all look fine!

VM forum staff would need to take a closer look at these - they should pick this up shortly!

Re: Constant iplayer buffering and huge lag spikes when gaming

Post up all the network logs.... and also a BQM as below.
______________________________________________

If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.
