WiFi Calling no longer working after my FTTP upgrade

Smack — Thu, 07 Dec 2023 17:51:28 GMT

I upgraded my broadband to full fibre a week ago and all went well and as expected. I do however have a major problem...

I have a poor mobile signal in the house and knowing I'd lose my landline after I switched to fibre, I decided to move my mobile phone service from Giffgaff to an operator who offered WiFi calling. I settled on 1p Mobile who use EE and also include WiFi calling as part of the deal. I was still on my regular broadband at that point and it worked beautifully. I could make and receive crystal clear mobile calls in the house even in rooms where there is no signal, reassuringly the words WiFicall would magically pop up next to the carrier name on my phone as soon as I walked into the house. It worked like a charm for a week.

The day of my transfer to full fibre duly arrived. Wi-Fi calling was still active on my phone when i got up, the engineer arrived and did the upgrade, all seemed fine until later in the day i noticed WIFI calling had gone and it hasn't worked since.

I've spoken at length to 1p Mobile who in fairness have been very good and they say all the settings at their end are correct, they've even issued me a new SIM just in case that was the issue. I've also done everything Apple suggest (I have an Iphone 12 mini) including resetting my mobile data etc etc. The time honoured trick of turning on Airplane mode and Wi-Fi simultaneously does nothing either. It's baffling.

Logic dictates, therefore, that it must be the upgrade to full fibre that has caused this issue as I've exhausted pretty much every other possibility, but that seems unlikely, or is it?

Am I missing something here? Any ideas would be most welcome.

Are you still using the same router as before?

Just a wild stab in the dark, but it could be worth checking that IPv6 is disabled.

I probably should have mentioned I use a Tenda AC1200 Mesh system with the WiFi from the Plusnet Hub2 turned off.

Anyway I've just logged into the hub and IPv6 does appear to be disabled.

While logged in I've turned the hub's WiFi back on and connected my phone to that instead. So far it hasn't had any effect on the WiFi calling issue.

We've got 3 x 1p mobile phones and FTTP and wifi calling is working with all of them fine.
So I don't think it's a general issue.

In that case have you checked your IP address is recognised as being in the UK? There have been various problems where an IP block is reported as being non-UK by some geolocation services, and your IP address will have changed with the new connection.

Edit: I should add that I have no idea whether 1p mobile care about IP address.

Stupid question maybe, but is the phone connected to the correct Wi-Fi address?

Are you still using the Hub Two?

How are the Tenda AC1200 Mesh system WAN configured?

@jab1, actually, that is a good question - however I assume that as the same router is being used the Wi-Fi SSID and password are unchanged.

Re: WiFi Calling no longer working after my FTTP upgrade

jab1 — Thu, 07 Dec 2023 18:38:37 GMT

@corringham I assumed that too, but I have known phones to 'lose' the Wi-Fi address - got me once.

Re: WiFi Calling no longer working after my FTTP upgrade

Smack — Thu, 07 Dec 2023 18:43:39 GMT

Yes I am connected to correct WiFi.

Thinking of the IP address idea...I do use AVG mobile security but with the VPN off. However, I usually have the secure browser function 'on' and the sets up a local VPN thing. Anyway I've switched that off too to see what happens. My phone is connected directly to the Hub Two right now so the Mesh system is eliminated as a potential issue.

I emphasise however that WiFi calling was working fine with my current setup before my FTTP upgrade.

That's my thought quashed then. 😀

@Smack

So confirm, you have the Hub Two WAN connected to the ONT and the Tenda AC1200 Mesh WAN port connected to a LAN port of the HUB Two?

How have you configured the WAN port of the Tenda AC1200 Mesh, you might have accidentally created Double NAT.

Re: WiFi Calling no longer working after my FTTP upgrade

corringham — Thu, 07 Dec 2023 18:53:16 GMT

@Dan_the_Van, the router and mesh were unchanged so there shouldn't be any double-NAT, but it is reported as failing with the router Wi-Fi too.

This is a strange one...

@Smack Has Wi-Fi calling got disabled somehow?

Re: WiFi Calling no longer working after my FTTP upgrade

Dan_the_Van — Thu, 07 Dec 2023 18:56:32 GMT

@corringham

It would depend how the Tenda is configured, if I was @Smack I would put the Hub Two in a draw and set the Tenda WAN port to PPPoE. There really isn't any need for the Hub if the wireless has been turned off.

Re: WiFi Calling no longer working after my FTTP upgrade

Smack — Thu, 07 Dec 2023 19:28:16 GMT

As connecting to the hub directly hadn't yielded any results I'm back on the Mesh now. Looked at the settings for the Mesh it's set to DHCP not PPPoE is that my issue? PPPoE seems to requires me to create a Username and password and I get a warning to the effect it may screw things up when I start to do so. Is it worth a punt or should I leave it?

I'm right on the limit of my very basic technical knowledge here so please be gentle lol.

WiFi calling is definitely on btw.

Re: WiFi Calling no longer working after my FTTP upgrade

corringham — Thu, 07 Dec 2023 19:37:02 GMT

Basically, what Dan is suggesting is to enter your Plusnet username and password in the mesh PPPoE settings, and connect the mesh directly to the ONT. The Hub2 isn't needed as it isn't adding anything other than the PPPoE connection - which the mesh can do itself.

At the least it will save a little electricity!

Edit: having looked at the Tenda mesh specs online, it appears to only have a 100Mbps ethernet port - how fast is your FTTP?

Edit2: Ah, I see there are more variants - some do have 1Gbps ethernet so you may be OK (depending on your model)

Re: WiFi Calling no longer working after my FTTP upgrade

jab1 — Thu, 07 Dec 2023 19:35:57 GMT

@Smack from my limited knowledge, if you take the Hub out of the equation, and set up the Tenda as PPOE using your PN credentials, you should be OK - I don't know what the 'warnings' are.

Also, I don't know what Apple told you to do, but try disabling/re-enabling Wi-Fi calling on the phone - if that doesn't work, try rebooting the phone - making sure Wi-Fi calling is enabled before you do.

Re: WiFi Calling no longer working after my FTTP upgrade

Smack — Thu, 07 Dec 2023 19:37:48 GMT

The warning I get is...

'Internet connection is normal. Modifying the settings may cause disconnection'

I've done everything you suggest to my phone settings.... many times.

It may - or it may not.
