I don't know. That's why I asked the "Would it deny the LAN access to the WLAN?" Q.
My XP Etherneted Desktop (LAN) can see my Vista Wireless Laptop (WLAN) but not vice versa.
However I don't put that down to the BrightBox as it is exactly the same with my Netgear.
It did work once when I first set it up. I put it down to an XP/Vista incompatibility.
