I am also having to connect ethernet cables to the second router which then connects to the first router using a wireless bridge because I not aloud to connected them by ethernet cable. The second wireless router would be for a wireless access point and for ethernet cables.

What wireless router do you recommend to connect to a vr900 over a wireless bridge ?

Would a vr900 (first router) connected to a Archer C2 (second router) by wireless bridge work ?

I do intend to use a wireless range extender with the second rounter due to distance between my house and 3 static caravans, as  wireless range extender that is on my furthest away caravan cannot connect to my first round due to distance being to far away.
