Reply to: Apps/sites won't work on my home Wifi but will on other devices/networks

Yes, I did suspect the mesh and powered it off, leaving just the main router running. But that didn't solve the problem either.

Since the router long-reboot it has all been running OK. We have a lot of devices running, like several Alexa devices and smart plugs, firesticks, phones/tablets etc

My phone was the only device that had problems accessing certain apps over WiFi

A full reboot of the router solved this. Switched off the sky router for 30 minutes and then back on and it all looks ok.

Didn't want to do this because I wanted to find out why my phone was being singled out. But in the end gave up and well at least it looks like it's all working now.

Are you running a mesh network along the sky router?

My previous phone was a Samsung Galaxy and the new one is a Google Pixel 7.

Same version of Android? I think I did see on a forum that someone had this problem after an Android update and, after trying lots of things, they ended up reverting it.

The other Android devices which do work on the Sky wifi; are they a different/earlier version?

PS. which makes me wonder if the Samsung stopped working after an Android (auto) update.

You won't believe this.

I have the same problem on my new phone! And even with a replacement SIM card from Sky mobile (which I tried just to eliminate it as the cause).

Again, the issue only presents itself on my home Sky Wifi. Not on mobile data, and not on any other Wifi network.

This is messed up

Thanks all. I broke my phone and the new one comes this week. So hopefully won't have this issue any more. Will update once I know.

That's one way to solve the problem!

Indeed it's an IPv6 issue. Disable IPv6 on the Sky router, reboot the router and the problem will be gone.

But then wouldn't it affect all devices, not just mine?

Literally all other android and apple devices work fine with the same apps on the same Wifi.

It seems to be quite a common problem. Google brings up numerous threads about it eg.

https://androidforums.com/threads/ce...r-wifi.1290267

Unfortunately, there doesn't seem to be a single definitive cause/solution. Although IPv6 gets mentioned quite a bit.

PS. might be worth downloading and running the Netalyzr app mentioned in post #4 of the above thread.

Interesting too: Samsung phones have something called "secure Wifi" which can be used to protect on public WiFi networks. This doesn't change the i.p. address. When I turn this on, then the apps connect fine. I can't use this feature all the time so it's not a solution, but it must be something to do with encryption of data.

It isn't a huge problem that I can't access the apps - it's just frustrating - but it's one heck of a mystery that I can't solve yet! Like, why only my phone, and then why only on my Sky network?

The secure wifi is a vpn!

From the documentation, Secure Shield applies to all devices while Broadband Buddy has device specific settings.

Is there some firewall App on your phone, possibly built in to an AV App?

It sounds like it's a combination of 3 things: the phone, the network, and this specific app. However, I think you'd need to do a packet capture to get to the bottom of it.

On my phone I've tried
- setting a static i.p. for the phone and using Cloudfare or Google DNS (note that I can't change DNS on the Sky router itself)
- using my phone fixed-MAC or using a randomised one

I've checked Sky Shield and it is not activated, but anyway this would have affected all devices and not just my phone.

On the router itself there are no specific rules for my phone.

this sounds to me like a device specific filter.

Could be. The thing that's a bit odd though is it's only apps that are affected. Browser works fine through the wifi.
