Moving smart hub.

LowPingHunter — Wed, 26 Jun 2024 09:26:06 GMT

Hello everyone, just a question I've got in regards to my FTTP 900mb broadband.. an engineer visited my house and moved my hub from downstairs, that was right next to the ONT.. connected ONT to one of the ethernet ports next to it, and then relocating the hub upstairs using the ethernet port connected to downstairs...

Now... since then, all my devices only recieve 92mb download speeds, exactly 92, across 3 hard wired devices.. on my settings, advanced > the downstream and upstream says 100mb.. instead of 1000 or 900 that I'm expecting..

Any ideas? Wanting to see if there's something I can do before reporting it..

Thanks

Sounds like your internal wiring is cat5 not cat5e.

You can just move the smarthub back if it worked OK before.

The Ethernet cable from the ONT to the hub, is probably only capable of 100mbs. It needs to be CAT5E or CAT6, which are fully wired with all pairs in use.

Who fitted the Ethernet cable?

Before reporting what and reporting to whom ? ,
if your own wiring is defective that’s not really a problem that concerns BT or Openreach, it’s easily proven, just move the router back to its original position, if that restores the previous speed , then its the cable or Ethernet outlets are defective , 100Mb is an old standard , it could be that whoever provided the Ethernet network, ( usually the developer in new build property ) , has not terminated the sockets correctly, or the wrong type of cable was used , resulting in 100Mb and not 1Gb speeds over that connection…but that’s an issue between you and whoever supplied the Ethernet connectivity, and nothing to do with BT or OR .

If an OR tech moved the router to use this Ethernet connection, they obviously wouldn’t know of this defect but more intriguingly, why was an OR tech visiting in the first place ?

First check the patch cables between the ONT & ethernet port & the port upstairs to the Hub. As above, the cable sleeving should say Cat5e or above.

If they are, then replace them one at a time & test.If still no joy then your internal wiring is faulty or below spec.

He was there because of poor broadband speeds.. after he switched it, it actually did achieve 900mb for the first day. Then for some reason, it plummeted.. cat5e from ONT to wall.. and cat6 from wall to hub.. if BT or OR can't help, I'll contact a private engineer I guess.. the house is council, so I dount they will help.. but I'm determined to fix it.. as everything is hardwired to the box upstairs now.

I'll double check, but I'm pretty sure it's 5e from ONT to wall.. what's weird is, it did actually produce 900mb for the first day after the switch.

Ahhh.. ill have to get that changed then.. any ideas how much something like that costs? If it did turn out to be that

Have you rebooted the router/ONT? Sometimes the autonegotiation gets confused, especially if you have a device with a 100Mb card connected somewhere. Turn them both off. Turn the ONT on and let it come up, then turn the router back on.

For example, if I reset my router with just the old BT TV 2100 box connected the uplink on my switch sets to 100Mb/s and quite happily stays there until I reset it, irrespective of the computer being 1Gb

Thanks for the suggestion, I'll try that after work..

@LowPingHunter

Its the ONT and hub are probably failing to auto-negotiate the correct speed, due to timing differences between the two bits of hardware. This is actually quite a common problem.

https://en.wikipedia.org/wiki/Duplex_mismatch

Sometimes rebooting either the ONT or the hub, can fix the issue.

The alternative is to insert an 1GB Ethernet switch, preferably on the home hub WAN end, as that has the ability to correct most timing issues.

You would only be using two ports of the switch, so you only need a small one, as you cannot use the other ports as it would be on the WAN side.

At least that proves the internal cable is up to spec.

So check & change the patch cables & also try with just one device connected.

Cables very rarely fail so my best guess would be poor terminations at the ethernet sockets.

This is interesting, because I first discovered the problem on my new PC.. one of the steps I followed was to ensure the pc was full duplex 1000mb.. however, it was autonegotiation, I then switched to 1000mb hoping it would fix the issue.. shall I try doing the full reboot of both ONT and Hub? See if that will graft

Thankyou for the information

If it is an autonegotiation issue it may be as simple as unplugging the network cable and plugging it back in again while the PC is on. A full reboot will set everything back up from scratch though, so always a good idea.

Aright mate, nahhh that didn't work unfortunately.. I think it's probably the cabling behind the wall.. it'll get confirmed or denied Friday when an engineer comes.. if it is that.. do you know how much that would cost to sort out? Cabling behind the plate in the living, and I'm assuming the Cabling behind the plate in the bedroom.. (I've just cable managed all my devices nicely I could cry haha) putting it back downstairs is something I'd rather pay to avoid..

Who is coming on Friday , an Openreach engineer ?
If you have reported a ‘fault’ now that your router is connected on the end of an apparently faulty internal cable ( a fault that wouldn’t exist if the router were next to the ONT and not using this internal Ethernet connection ) and OR are visiting on what seemingly will be a waste of that engineers time ( service demonstrated OK at the point where OR are responsible ( next to the ONT ) and not OK at the end of a third parties cable , where you are responsible ) that’s the very definition of a chargeable call out , as it’s clear that nothing on the OR network is ‘faulty’ , the problem being on something not supplied or maintained by Openreach, that’s not to say a charge will be raised, but you couldn’t justify complaining if a charge is raised.

If you're not going to add nothing of value, please refrain from commenting.. the jury is still out on what the fault is.. I'm not an engineer.. that's why BT are coming out to investigate.. not sure why you have an attitude about it..

@LowPingHunter

If your last post was a reply to @iniltous , then I think that they were just trying to potentially save you from receiving an unnecessary bill.

I don't know what the current charge is, but 10 years ago, it was something like £128.

It's the second time he's commented with an obvious attitude.. I can do without unhelpful comments.. he's obviously got his knickers in a twist this morning..
