IPV4 fallback doesn't work

Adam_84 — Thu, 17 Nov 2022 09:11:04 GMT

Hi All

So I have seen a lot of threads on this, but still can't get my EE sim to work in my 4G CPE 3 mobile router on IPV4 only.

My issue is when set to dual stack (IPV4/IPV6) services like Steam, or even things like VPNs don't work. So I followed the steps suggested in other threads, that said I should make a APN of IPV4 only which I did, however once I do that and try to browse to anything I get an a message of APN: Connection failed. When I switch it to dual stack the connection works, but then I still can't access services I want to like steam or my VPN.

Thanks

Hi @Adam_84

Welcome to the community.

Hopefully someone with similar equipment will be along shortly to offer you some advice. Otherwise, I would recommend speaking to our technical support team to see if there's anything they can advise.

Hi, I met same issue here. My device is Huawei E5783-330. With the EE sim (30 Day Essential SIM Unlimited Max) and APN setting IPV4/IPV6, I can't login or even connect to the Steam software on my laptop, but I could still browse the Steam website. When I switch to IPV4 only, my router shows 'Internet disconnected'. The configurations I tried are shown below:

1- If I put EE Sim in my Phone and make my Phone as hotspot, everything works. I could now login Steam on my laptop with download speed around 6-7mb/s.

2-If I put EE Sim in E5783-330 with IPV4 only but use EE 3g Instead of EE 4g+. It still works. But I lose most of my download speed. Only around 1-2 mb/s.

3-If I put Virgin media Sim in E5783-330 with its default APN setting. Everything works.

4-If I put EE Sim in E5783-330 with IPV4/IPV6. I could view most part of the Internet. But I can't connect to game service like Steam or League of Legends.

5-If I put EE Sim in E5783-330 with IPV4 only. It shows 'Internet disconnected'

After the testing and reading so many threads about IPV4, I think it's the EE sim's problem. Are there anyone who knows how to fix this problem? It is really unpleasant to use 3g signal only 😞 . Many thanks in advance !! and apologize for any unclear expression. I am not a native speaker.

Assuming you are using the correct APN Profile, which if you check should be -

APN Profile Name = EE or Internet
APN = everywhere
User Name = eesecure
Password = secure
Type = IPV4
Authentication = PAP

As a Test only and without using any VPN, set up another APN Profile on the Router as follows -

APN Profile Name = something like TM IPV4 NoPass
APN = general.t-mobile.uk
User Name = leave it blank
Password = leave it blank
Type = IPV4
Authentication = PAP

Save it, set as Default, Reboot the Router, Test and report back your findings.

Chris.

Hi Chris,

Many thanks for your reply! For the APN profile, I double checked, and they are correct. I tried your configuration without using vpn, it shows 'Profile invalid' and under EE 3g, it is same circumstance.

Wish you have a good night and looking forward to hearing from you.

Hi Chris,

It seems this issue still exist. Do you know how to solve that?

Many thanks and have a nice day!

Hi Chris, didn't realise that I hadn't hit reply!

Tried your setting and had the same result as VittorioVeneto.

And can confirm my original problem still exists when I I use the EE profile.

Can't wait for this contract to be up, so I can stop paying for it!

Cheers

Hello!

Sorry for dragging this open again but I had a ipv4 only profile working for months and recently it has stopped working properly. Would this suggest EE have patched the ability to separate this or anything like that? Upsetting because things were good for a long time and now I'm back to rubbish NAT types.

LukeKW — Tue, 09 May 2023 23:05:52 GMT

i have the same problem now too this is very upsetting i was enjoying the moderate nat type on ee's mobile broadband ive trried changing it again and again still doesnt work so it looks like it patched

I am having the same issue with an iPhone 12ProMax.

EE useless so far.

Interestingly last week I was roaming in the EU and my iPhone on the EE SIM provided both ipv4 and ipv6 !
The same happens if (in the UK) I stick my EE SIM in an old iPhone - both ipv4 and ipv6 available.

Hi @edoardoc

Thanks for coming here.

Are you unable to connect to a device or VPN?

Leanne.

Hi @Leanne_T

I am unable to get an IPV4 connection on the mac when tethered/connected (via USB or WiFi) to my iPhone with the EE SIM.
So apps that are unable to use IPV6 on the mac (like my work VPN client) fail.
Common apps like a browser work fine with IPV6.

My corporate VPN client requires IPV4. Used to work connected through the iPhone until last December. Stopped working after the Xmas break.

I tried corporate vpn support, apple support, resetting iphone etc. - it's not a device problem. EE changed something.
While roaming with the EE sim and the same devices IPV4 works.
If I stick the EE sim in an old iphone, IPV4 works.

I am currently unable to use my phone as a hotspot for work. This is extremely annoying for me. If I need to work mobile, I either have to attach to some wifi or bring an old iphone and swap SIMs temporarily.

EE support understood the issue but said they can't do anything to change my APN.
The solution would be to change network, e.g. to Vodafone or O2 ... I just wish I hadn't renewed my EE contract.

Hi @edoardoc,

Are both iPhones using the same iOS version?

James

Re: IPV4 fallback doesn't work

edoardoc — Tue, 20 Feb 2024 17:24:03 GMT

Hi @James_B no the old iPhone 7 is on an older iOS version.

my regular iPhone is a 12ProMax and always on the latest iOS, currently 17.3.1

the spare one is an iPhone7Plus on iOS 15.8.1

as I said, I was able to use my regular iPhone until Xmas more or less, when iOS was 17.2 I think, however the current release worked fine while on roaming last week. The problem is with the carrier, not with my devices !

James_B — Tue, 20 Feb 2024 17:31:57 GMT

Hi @edoardoc,

If it was purely a network issue, I would expect the issue to follow your SIM and show the same behaviour in all devices. In this case it seems the issue only appears when using your EE SIM in a device using newer versions of iOS.

I'm not aware of any known issues that would cause this so I'd recommend getting back in touch with Technical Support on 150 to see if the team are able to raise a support ticket for further investigation.

Hi @James_B

as I said, last week I was roaming in the EU with the same devices (iphone and mac) using the EE sim and I was obtaining both IPV6 and IPV4 - so it's not an iOS issue

>getting back in touch with Technical Support on 150

I spent an hour today and they understood the problem but said that they are unable to change my APN, they did not offer to open a ticket

Re: IPV4 fallback doesn't work

James_B — Tue, 20 Feb 2024 18:19:31 GMT

Hi @edoardoc,

I understand your frustration and did pick up on your comment about it working as expected on a roaming network.

The iOS version does seem to play a part, as the issue isn't present on older iterations.

I'd recommend getting back in touch to see if it is possible to raise a ticket with our support teams for further investigation.

Please let us know how you get on.

EE should just offer up IPv4 and the issue would be fixed. It's unworkable for me with my home VPN or works VPN.

Clearly this is something that EE haven't properly tested, regardless of whether Apple have made changes or not.

You'd like to think that EE's network would work well with top of the range Apple hardware and standard business VPNs but it seems not to be the case. No one has time for hours of calls with 150. Quicker to change networks and send the iphone back to EE as being useless and not providing the function it was brought for.

There's several threads around this same topic.
