A little bit of background.

my current provider is Virgin Media 250mbs

up until last week i installed the new Archer router which the VM box in modem mode.

my portal was working fine up until yesterday afternoon, now it gives me internet error ever 10seconds or so.

my PS5 in hard wired into port 1 and im sat 6-7ft away from both the router and the ps5

Today i have given the PS5 a address reservation under dchp server, and ive since port forwarded the following ports

however the above still hasnt solved my problem

if anyone has any ideas that would be great
