Plusnet one router won't work with a 6m long ethernet cable

norm90 — Sun, 01 Sep 2024 14:01:54 GMT

Hi
I am using a roughly 6m long cat 5e cable to run to a network switch upstairs. But it won't work, it will work fine with a shorter cable just not a 6m long one.

As a work around I am now using another switch plugged in to the router. So router - switch - switch.

Works fine on this setup so proves there's nothing wrong with the cat 5e cable.

Why won't the hub one work with the 6m long cable?

Thanks

Have you tried different ports on the Hub ?

Yes I have tried all 3 of them no differents, even had a new router sent out and still the same. At work we have a BT router which I'm told is the same but a different colour and that one is working with a 30m cat 5e no problem.

@norm90

Have you tried the 6m cable with something else? To me it appears faulty.

I currently have the cable plugged in with a switch either end of it and works fine, plug it directly in to the router nothing no light's.
Worked fine my old Netgear router.

@norm90 Could the cable be a crossover cable ? Switches may autosense and correct but not sure of the hub.

Just checked no both ends are the same. T568B

@norm90

Can you beg, borrow or "steal" a 6m (or longer) ethernet cable from some where to try.

Hi
Got another cable that was a similar length, still didn't work no mater what port I tried.
I then used the same cable to go from switch to switch worked perfectly.

just to understand, connecting hub to switch, switch to switch, switch to device works ?

Yes correct.

How about removing the first switch so connecting hub to switch using long cable,, switch to device ?

If I go hub-switch-device it does not work with the long cable or the one I have borrowed.
But hub-switch-switch-device works for both cables.

I’ve read similar things on the BT forum which of course uses the same router…

This issue has been reported before, and an Ethernet switch has cured the problem. Ethernet switches are capable of matching different speeds and compensating for timing differences, as they have internal buffers.

@spile thanks, you've confirmed my suspicion that the Hub2, which is a switch, was introducing errors that the external switches were correcting. Very difficult to prove remotely hence trial & error.

@norm90 Seems to have options, stick with what works, convince Plusnet to replace Hub2 with no guarantee things will change or replace Hub2 with another brand.

Surprised that Plusnet users haven't already raised this problem in large numbers previously.................................

FWIW - not sure if this is of any interest or directly relevant...

Just out of curiosity - I've dug out an old, super cheap, 15 metre cable, cat5e 10/100BaseT (supposedly) - cost me £2.38 (!) inc delivery, from an Amazon third party seller, back in 2011.

Seems to work absolutely fine between my PC and recently supplied Plusnet Hub Two (as it did with ADSL2+ router(s) 'back in the day').

Might be worth considering getting a Hub Two - plenty on eBay, or possibly 'free' from Plusnet if upgrading/recontracting (?).

They sent me a new. Still the same problem. Might just got back to my old net gear router.

Just to clarify - so did they sent you a new Hub One, or a new Hub Two?

Something very odd if both wouldn't work with a mere 6 meter of LAN cable.

Sorry it's a new hub two that replaced a hub two.

Sounds to me like that 6mtr cable is faulty in one way or another.
