Apologies if this has been discussed to death, but I can't find a solution to my problem in the threads.
I have a Huawei B315-22 4G router with an EE sim. The default APN (everywhere, eescure, IPv4 and IPv6) allows me to access the internet on all devices. It allows access to streaming services like BBC sounds, Spotify and Iplayer on PC and iPhones, but NOT via Android phones. I can access websites and email OK on Android phones, but Spotify etc will not connect.
When I access the router settings, I see the default EE APN is set to "IPv4 and IPv6" (which i can't edit). If I set up a new APN (calling it 'EE internet', with username 'esecure' and password 'secure' (although it seems own set it's own 8 digit ******** password regardless of what I enter), I can set the IP to IPv4 only. I set this to default and hey presto, it all works fine. I can access everything on all devices. So far so good, but the moment I reboot or unplug the router, when it reboots, I get no access to the internet at all on any device. So I have to go back in to the router settings and reset them to the original default (IPv4 and IPv6), and i'm back to square 1.
Interestingly, on another Huawei router (B535) with a different EE sim, the default EE APN is set to IPv4 only, and it works fine for all apps on all devices.
Please can anyone help me sort out the problem on the B315-22? Do I need ot get a different router, or a different SIM?
