help please, 1GB broadband very slow

[thealarman]

i had 1gb fibre installed a few weeks ago. utter rubbish, its no faster than it was before,  its actually slower.

the first hub5 they sent me out had a fault on it, virgin was unable to see the speeds i was getting at the router, so they sent me out a second one.

i fitted the second hub,  on a wifi connection i'm able to see a 600mb on the speed test sites, sam knows says it well over 1GB at the router and 600mb at my laptop.

but when i do the same test on my PC (hard wired with cat6) i only get 300mb. now i have a 1gb network connection in my PC and i have recently fitted a 2.5GB card in the computer, this did not improve the download speed.

i had the VM engineer out today and he replaced the F connector on the end of my coax and the 2 splitters on the property, He also moved me to a better connection point in the cab box up the road.

none of this has made any difference to my internet speed. 

when i was paying for 100mb i got 100mb

when i had 350mb i got 350mb

when i had 500mb i only got 300mb

and now i have 1GB i still only get 300mb.  its as if the router is bottle necking the bandwidth on the hard wired network ports.

I have never heard of a system where the WIFI is faster than the Ethernet before.

can anyone help before i pull all my hair out?

I used Avast years ago best thing you can do is uninstall the web scanner stuff but really you don't need it.

Chris, I tried switching off avast premium late last night and it made very little difference to my internet speed. I really don't want to go to the trouble of formatting this machine, so I might just replace the drive and do a fresh install of windows 10 just to see if this cures the problem, if it doesn't help I can put my  original SSD drive back in.

Disable the startup apps, one by one, with a reboot in between, to determine the cause.

hi again, i disabled ALL of the start up apps to see what would happen and switched off the avast software.

these were the results

fast.com 600mbs

Sam knows 1150mbs at hub, 179 at router

when i switched it all back on i got

fast.com 320mbs

Sam knows 1147mbs at hub & 176mbs at computer

The speeds to the Hub look fine, are the network drivers up to date in the PC? What speeds are the network card capable of in the PC?

"Avast antivirus, full version"  - once installed this type of package inserts many hooks and additional processes into the computers networking.

Just be because the Avast appears to be set to off does not mean it is removed from bandwidth limiting the network path.

It may require total uninstall of the Avast product and any other Safe Browsing tools to open up the computers network performance.

That the computer works well in safe mode shows the hardware is solid and a Windows rebuild is not required.
