Hub Gone, but Old WiFi Networks Still There

[Issonian]

A few weeks ago EE came along and installed a full fibre connection to my home and supplied a new EE hub with the network name (say) EE2025ABC. I connected my computer, iPad and iPhone to EE2025ABC and everything worked fine. I sent back my ancient BT hub that had the networks (say) Banana24 and Banana50.

A while later I found that my mobile devices had connected themselves to Banana24 and still worked fine. How can this possibly happen? The hub that supported this network has long gone, but when I look at the network list on my devices the two old networks are still there as large as life and can be connected to. Can anyone explain this seemingly impossible situation? I do have three Devolo WiFi extenders around my home should this be relevant.

Yes

Hi Liquorice, I see that you’re saying that the presence of the Devolo extenders is relevant, but why is this? I thought that extenders only extended the network created by the main hub, which is just the new EE network in my case. Why would the extenders extend networks that are no longer present on the hub?

You need to change the network name ( SSiD) that they were broadcasting when paired with your old router.

You have to pair them with your new router so that they broadcast that name.

If one of the Devolo units is connected to the hub via an Ethernet cable, then disable the WiFi on the hub and just rely on the Devolo mesh as it's already set up!

Thanks for your advice, but I don't know how to do this. If I switch off the Devolo central hub and the three extenders and then switch them back on again, will this do the trick? Will this make them forget the old network names and find the new EE network name?

Just factory reset them and set them up from scratch again.

Does it actually matter what their network name is, you can still use them as they are.

Such is my lack of knowledge around this subject, I am assuming that the old networks associated with my former BT hub will be constrained to an ancient WiFi standard, whereas I want my Devolo devices to work with an up-to-date WiFi standard that I assume that I assume my new EE hub and its network supports.

No. They have nothing to do with your old BT hub other than broadcast its network name.

They will work as always which depends on what they are designed to handle.

ie. rubbish in rubbish out. Good in good out.

It's just a label to identify the network, you can call it Fred if you like, it has absolutely no bearing on performance.
