Odd network speed problem

Hi guys,

Bit of a weird one.

I have my bedroom computer connected via a home plug, it gives me 100mbit from the virgin hub downstairs.

Yesterday it started messing around where my computer is only getting 3-4mbit and horrendous ping, the odd thing is if I connect the exact same ethernet cable into my laptop the laptop gets a perfect 100mbit and great ping, so appears as though something is wrong with the computer.

Tried resetting my network adaptor, updated it etc but have no idea what's causing this huge loss of speed on the computer :confused:

Did you check to see if there's a process consuming majority of the bandwidth? That could explain a big drop in throughput and ping.

When connected via the Powerline adapters, do you get any packet loss when you ping the Virgin Media Hub?

Can you temporarily connect the computer directly to the Virgin Media Hub and see what the difference is? My gut feel is that the Powerline adapters are the issue rather than the computer.

I had this with some Netgear homeplugs before, same kind of scenario. Restarting the homeplugs would fix it for a bit, but then after some time it would go back to only doing a few mbps again.

Swapped them for TP-Link ones and the problem went away for me. TP-Link ones been pretty reliable with the odd reboot every few months.

Hiya guys, thanks a lot for the info. I rebooted the computer and opened up task manager, this is what I am seeing

That service just stays there and I haven't opened anything at all, I ended the process and the network returned to normal.

Any idea what it could be?

Thanks!

So yours is actual usage, mine wasn't.

Go to task manager > performance > open resource monitor at the bottom > check the network bit for highest send/receive byte values. Should give you a process ID (PID) and address it's talking to.

Could be a big old windows update?

Turn off Delivery Optimisation. Microsoft should have that as opt-in and not enabled by default.

Go to Settings, Update & Security, Advances options then hit 'Delivery Optimisation' and disable it from there.

Hey guys thanks again for all the help, it turned out to be the delivery optimization, it was at like 80% in the background downloading. All sorted now , cheers!
