Ps5 not connecting to the internet

[Noman]

About 3 months ago my Ps5 stopped connecting to my internet even though every other device connects and works to the internet. I’ve read multiple other posts about this and have tried changing dns settings but it still doesn’t work. Can somebody please help me to solve this issue?I use Zyxel NR5103E.

If it’s the same issue I’ve been having, try logging onto 192.168.1.1 and changing your connection from 5g to 4g. Slower connection obviously but it sorted the ‘authentication’ issues on 5g. Firmware b14 seems to have introduced issues with things like online banking, certain websites and PSN for me. A new firmware update will hopefully sort this.

I had this issue at my dads, turns out something to do with the IPv6 screws everything up. Disabled that and it worked straight away.
