I'm looking to buy one or two RE305 extenders to supplement my VR400 V3 modem/router. I want to ensure that I get the V3 hardware version of the RE305 so that it gives OneMesh capability with the router. However, no supplier seems to be able to confirm that they are supplying the V3 version - this applies to both large retailers and Ebay sellers. The OneMesh capability is attractive to maintain a single network name over the house so I want to ensure that this is what I buy if possible.
