5G Router - Xbox Series X Multiplayer Issue

[B1gWill87]

Hi

I have recently started playing online on Xbox, and only have my EE 5G router to connect to. I seem to be able to connect to games without any issues, however I cannot join parties or connect to voice chats etc and on checking my network stats on the device, I get an error about my MTU being too low (1382).

How can I fix this?

Thanks

You are probably finding yourself up against a limitation of EE's mobile network. The EE mobile network uses Carrier Grade NAT (CGNAT) resulting in a double NAT, which games consoles often object to, which means you don't get your own public IP address but share it with other users. So you can't be uniquely id'ed on the Net & therefore your LAN cannot be addressed from outside for unsolicited accesses. This is unlike fixed BB. 

If this occurs there is nowt you can do to avoid it. IMHO Mobile BB is not suitable for gaming.
