@BulbyMcBulbface Have solved the issue. For anyone needing future reference, this was a DHCP and ARP issue, for some reason the V2 L530E made a mess in the router and tried to steal other devices...

Greetings, I bought an L530E the other day, all seemingly worked fine, got it paired and working nicely. Later that evening had some odd 'network fluctuations' where other devices would get booted...
