5gee router with multiple devices issues

[Leonkenworthy]

Hello everyone! 

Recently (last few months) moved to the 5Gee router with external antenna because the copper lines to the property I live at are extremely poor. The village has had a 5g mast put up and just waiting for activation so I can have decent 5g connection. In the meantime I'm using 4g and to be fair the speeds are fantastic! But here's the issue. If I'm on the ps5 online and fancy watching something on my phone at the same time, my connection bombs out completely into un-useable land. Lag and all the fun stuff you definitely don't want. I've had home broadband routers for years on much much worse speed connections and been able to use multiple devices at the same time with no issues. I assume it's because it's a Mobile internet issue but maybe a router settings issue hopefully? Any advice? Please

Please clarify whether the mobile phone & PS5 are connected through the router or are directly on the mobile network?

Thank you for your reply, 

Both are connected to the router, the ps5 is wired and the phone is obviously WiFi.

It might be an EE IPv6 issue. EE has introduced IPv6 on its mobile network, but it doesn't fall-back to IPv4 nicely. Can you change the Profile/APN on your mobile router to APN Protocol = IPv4 only?

I've actually tried this before after seeing this idea in another thread some time ago and it seemed to drop all connection completely. Did I need to wait longer? 

[XRaySpeX]

Don't think so! It'll either work or won't. You could try IPv6 Only.

[Leonkenworthy]

I will try again when I am home and see if it 1, works and 2, helps. 

Anything else I could do or consider??

[Leonkenworthy]

Also do you know what the correct settings are for setting up the ipv6 only profile???

[XRaySpeX]

Only what I told you. You probably can't amend the current profile but would need to create a new 1 & then mark it as default.

[Leonkenworthy]

Soooooooo! 

I've set a second profile up as ipv6 only and ran a test or two and everything seems hunky Dory right now ☺️ 

Was able to play online and stream a twitch stream at the same time. I am quite excited. 

Thank you very much for your help and time
