I want to remote control a media centre that uses the wireless network on VLAN 2 (192.168.2.x), but the main PC has a wired ethernet connection (192.168.1.x)
There are three issues here, the VLAN (which can restrict where traffic goes), the IP addressing and the "wireless isolation" issue being discussed elsewhere here about printing.
I don't think there's enough of us know enough about the brightbox TBH, but in general terms...
Using a subnet mask of 255.255.0.0 will allow devices on 192.168.1.x and 192.168.2.x to ping each other via a switch without the router picking the packet up and forwarding it to the WAN port. The 255.255 defines the network and the 0.0 the clients.
VLANs are capable of keeping traffic isolated, so I don't know.
Wireless isolation may prevent the Wireless to LAN or vice versa traffic. What are the addresses on VLAN1, and can you ping between things on there and on a wired connection ?
MaxDSL - goes as fast as it can and doesn't read the line checker first.
