Newly installed Gig1, no more then 420mbps speeds

Hi, 

Looking for some help, I have recently (around 4 weeks ago) had Gig1 installed into my house. My issue is I have never even come close to the "Gig speeds" which I was expecting, the most I can seem to get is around 420mpbs if I'm lucky but generally around 340 is the average. 

I've tried using CAT 06 cables and CAT 07 to no avail. I've also split the 2.4ghz and 5ghz wifi connections incase and still only achieve the above speeds. Trying to contact Virgin just means really long wait times. A bit frustrated as although speeds are far better then previous ISP, I'm not getting close to what I'm paying for.

Not sure what else to try. Running SamKnows it connects to the router but gives no Data which is a little odd. Just really looking for some guidance to come to a solution! 

 

Matt

Re: Newly installed Gig1, no more then 420mbps speeds

Are those wired or wireless speeds, and tested via what device/s?

Re: Newly installed Gig1, no more then 420mbps speeds

Could you share your hub connections stats

Hub Stats:
Open http://192.168.0.1/ or http://192.168.100.1/ (if you have your Hub in Modem mode) in your browser

For Hubs 2 & 3 - DO NOT LOG IN, just click “Check Router Status”

For Hub 4 - When the page appears LOG IN then click on: Advanced Settings > Tools > Network Status.

Please copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs in replies here.

If this is your first time you may have to do first setup of hub password.

If I've helped please let me know 🙂 Matt

This should be QAM4069 and is likely why you're not getting full speeds.

Reboot the hub and check all the cabling is secure on both ends

so now showing as QAM4096 - Getting a much more reasonable 720mbps on wired connection and 380 upstairs. so definitely a significant improvement Wifi is still "sluggish" around 340 downstairs in direct sight of the router and SamKnows still doesnt work! but yes, definitely a bit better I think
