Smart Hub 2's ethernet ports stopped working

SmallJSP — Sat, 20 Sep 2025 21:17:17 GMT

Hello,

I have two NAS devices plugged in to the rear ethernet ports of my Smart Hub 2. I've had them for years. Suddenly they are not showing on the network and going in to the router's settings under My Devices indeed shows that they are not connected. It's as though the ports have suddenly been deactivated. Caused by a firmware update maybe?

Unplugging and restarting everything has not worked so far. What can I do to get these devices back online?

Thanks

What firmware version is it?

You sure that's a Smart Hub 2? The latest firmware is about due for an update, (I suspect), but the current version is v0.45.00.08028-BT

It definitely is a Smart Hub 2. At the top of page at 192.168.1.254 it says 'Smart Hub 2 Manager'...

Very strange. That almost sounds like the orginal firmware.

Sorry, outside my experience. I'll defer to the more experienced guys to answer then.

Yep, bit of digging suggests v0.17 dates from Dec’19.

The guy having problems then did a back-up of his settings followed by a factory reset. That seemed to get it updating again. I’m not sure if that will fix your ethernet port problem or not though.

Right, OK, I will do a backup of router settings and then a factory reset and report back.

There's no way to update the firmware manually? I don't understand how it says the firmware was updated this week, but the version is from 6 years ago...I think I only got the hub in 2021...

So just because of the construction of the router, assuming you are on FTTP (full fibre) and assuming you've been using the two LAN ports furthest from the WAN port, try the LAN port next to the WAN port. In most cases, thanks to the design, if there is an electrical issue, you'll lose 2 ports, but not all 4!

the router is faulty tell them the ethernet ports are dead no amount of research will make this any diffrent

the fact that it was working and now it isnt suggest something has died

had the happen on a competitors router once

if you pluge in 3 or ports a certain port wouldint work and was just dead

No need to complain, from my experience BT are more then happy to replace faulty router's.

Ring them tomorrow, and if they can't find/fix the issues with the router you'll have a new SH2 crashing through your letter box by Friday.

@Kodikid @SmallJSP only put a complaint in if they refuse to change the router of course

Hello,

Thanks for all the replies. I was going to do a factory reset, but instead rang up BT and pretty quickly they agreed to send me a replacement router. Should arrive later this week.

Now, I wanted to do a backup of my settings to potentially import once the hardware is swapped over. I go in to Home>Advanced settings>System, then Back up/Restore, click on the 'Back up' button...and it goes to a 404 (looks like it should be 192.168.1.254/etc/config/hub.conf) !!

A backup made on one hub can't be restored to another hub.

Unless you have made many configuration changes such as port forwarding, there is little point in a backup in any case.

When you new hub arrives, simply change the network name (SSID) and password to that of the old hub to avoid changing on multiple devices.

what do they do once router is returned do the use the same (SSID)

or do they pull it from service ?

the chances of getting the same (SSID) in the same area is non existance i know nut still interestes me

SSID don't need to be unique (they're local, like your computer name), you could manually change it to whatever you wanted. Even if you were to use the same SSID, if you set a different password you could have two networks with the same SSID, but clients would only be able to connect if they had the password for the SSID/combo they are closest to!

My SSID carries enough info that my neighbours can see it's mine, but the password is strong - nothing is unbreakable, but you are not going to break it without a sweat!
