I've had my Hub One for a while and it was working fine, including using my work VPN. However, the VPN started having intermittent problems some time ago, but I've only just narrowed the problem down. It seem that if I connect wirelessly to the router everything is fine, but if I connect wired then the VPN only partially works. Only subset of my company intranet sub-domains are accessible. If I hard code my company DNS on my laptop then I can get these to work, but that has performance issues and means I always have to run the VPN.
Any suggestions on how to fix this would be greatly appreciated.
