The Admin Page Said the WiFi Name Was Changed. The Phone Still Saw the Old One, With No Password (Telstra Router, Brisbane)

This one arrived as a message rather than a job: “I renamed the WiFi, it says it worked, and nothing changed.” It is the kind of problem people assume they have caused themselves, so they repeat the same steps four or five times before asking anyone. In this case the steps were right the first time. The router was not doing what its own admin page said it was doing — and while that argument played out, the network everyone could actually see had no password on it.

Where the change was lost

Admin page

shows new name

Router wireless hardware

never applied

Fault here

→

Broadcast network

old name, open

→

His phone

old network only

The settings were saved. What never happened was the router pushing them out to its own wireless. Normally you can watch that happen: you press save, the WiFi indicator goes out, and a few seconds later it comes back on with the new network live. Here the admin page held the new name even across a power cycle, while the air carried the old one — and the old one was still open, with no password. Settings stored in one place and never applied in another is a software fault, not a mistake by the person typing.

What a normal rename looks like, so you can tell when it fails

Renaming a network is one of the few settings where the router gives you visible feedback within seconds. Knowing that feedback is what lets you stop guessing.

You save the change, the WiFi indicator on the router goes out, and a few seconds later it comes back on. That is the hardware applying the new details.
Every device drops off at that moment, because from their point of view the network they knew has gone. That is expected, not a fault.
If the light never blinks and nothing disconnects, nothing was applied — regardless of what the admin page claims.
Check from a device that has never joined the old network. A phone that has joined before can show you a remembered entry and confuse the picture.

How it was solved over messages

Confirmed the symptom precisely: admin shows the new name, phones show the old one

Not a phone cache issue

Walked back through his steps and the screens he used

Procedure was correct

Checked what a power cycle did — the split persisted in both directions

Points to the router, not the user

Flagged the immediate risk: the visible network was open, with no password

Worth fixing the same day

Advised a manual factory reset, then reconnect and set the network name again from clean

New name applied, reported fixed

Three reasons a saved setting does not take effect

	What is happening	How to tell them apart
Saved elsewhere	The change went to a different band or a guest network	The old name is still listed in the admin page too
Device is remembering	The phone is showing a remembered entry, not a live network	Another phone that has never joined sees the new name
Not applied at all	Admin holds the new name, the air carries the old one	A power cycle changes nothing in either direction
This case	Third kind — on a near-new router	A manual factory reset cleared it

Two things are worth taking away from a fault this small.

The open network is the real risk, not the wrong name. A network with no password is one anyone within range can join, and it stayed that way for as long as the rename appeared to have worked.
A factory reset is the right tool here precisely because the fault is a mismatch between stored settings and applied settings — the reset throws away both and starts again.
Know the cost before you press it: connection settings and any custom network name and password go with it, so have your provider's details to hand first.
This is the second time we have seen this exact behaviour on this router model. If yours came from the provider on connection day and behaves this way, you are not doing it wrong.
If a reset does not fix it either, that is worth reporting to the provider rather than living with — a near-new router that will not apply its own settings is a replacement conversation.

Result

Root cause: the router stored the new network name but never applied it to its own wireless, so the admin page and the broadcast network disagreed — and a power cycle did not resolve the split in either direction, which ruled out a mistake in his steps. Meanwhile the network everyone could still see was open, with no password. A manual factory reset followed by reconnecting and setting the name again from clean applied the change, and he confirmed it worked. The second time we have seen this behaviour on this router model, on a unit that was only days old.
