After some help, I’m on a 1gb package with the SH4. Via Wi-Fi I’m getting speeds of c.400mb but via Ethernet it’s only around 100mb.
I’ve checked the splitter and it’s rated 5-2000 so think that’s a ‘newer’ splitter.
samknows/real speed to hub is showing <100mb.
Do I have an issue with my SH4 or potentially with the service itself?
Any thoughts welcome.
thanks

Thanks John
Hopefully this is the right data below. Did a quick test on samknows and still showing <100mbs to Hub. Look forward to your feedback.
cheers

Thanks, ran a few pings this morning and it looked to spike.
Would assume it's a faulty hub then as first suspected. Is there an easy way to contact support to get a new hub sent out or will I have to go through their diagnostics first?
thanks for your help.

Hi @Arpy, thanks for your further replies.
I can see that you've already spoken to our team directly on this one, and have managed to get a technician booked in to visit you to get the problem resolved.
Please let us know if you're having any further problems once the technician has visited!
Many thanks

Thanks @Tom_W1, @John_GS and @jbrennand
The engineer came out on Friday - no issues were identified inside the house, all levels were fine, splitters ok so a decent signal reaching the hub. They identified the issue as being a fault with the 'upstream levels' on the streets network. The networks team came out the same day to resolve. Pleased to say i'm now getting very strong ethernet speeds and samknows is showing >1,150mbp to Hub consistently.
Thanks all for your help.

Hi,
So I moved to a property and have th 1 gb fiber installed, great upgrade over 40mb's whihc i had at my old place? Anyway after settling in i kept an eye on the speed and noticed wild fluctions after the hub, the speed to the hub on Sam knows was steady at 1147, after this to my ethernet connected lapt and desktop at time saw speed of 170mb/s whihc made no sense. Tested on my iphone and and that reported 800/900 mb/s on wifi whihc is like what the hell.
My friend who also 1gb VM up the raod and an identical desktop the only veriant is on the motherboard is getting 950mbs from hub to machine!! He told me his cat 6 cable did not cut it and cat 7 was the way to go. So OK I bought cat 8 and it made not difference. So driver updates, bios updated, removal of ethernet drivers, trying both the gigabit and 2.5GB ehternet ports, windows update nothing made a difference. Same on the lappy, its ruuning win 10 pro and desktop is win 11 pro. So even more what the hell. sometime the test stays at 600mb/s and then nose dives to 100 - 200mb/s!!! I tried tcp optimizer as well.
In the end talked to the coolest customer service guy there is, we went through and he says man you tried everything easyiest ticket he raised. I even sent this article. Today the engineer comes and he test the cabinet everything is good and i demonstrate, he checks sam knows, and speedtest.net. Next he says can I install the speed test app locally sure why not, we run it and get 950mb/s sustained not drop or anything. OK also try on laptop and same results, run on bothj and the speed is split but adding up to 950+ mb/s
So not the hub but something impacting the browser and throttling it!! on 2 machines. on I have full control over the other not so much. I tried, chrome, edge and fire fox, somethign effecting all 3!! On the desktop (mine) I have Sophos home part of that is web protection I disabled the web protection and bingo sam knows now reports over 950 mb/s sustained. So 2 choices for those out there try the speed test app first if you get bad speed between hub PC especially on ethernet conenctions.
Fyi also let the engineer know so they know about false info being reported. I apologised for wasting his time today
