I use my laptop (Windows 7 Pro 32-bit) in two modes, sometimes connected to a docking station, other times connecting by WiFi to a router, Netgear DGND 3300. To get Filezilla FTP Client to connect by FTP to my website, I find that I need to assign a fixed IP address to the laptop, and would like this IP address to remain fixed in either mode of operation, docked/undocked.
I reserved a local IP address (192.168.0.9) for the laptop via the router admin page - LAN Setup > Address Reservation. However, if I do this in one mode, say undocked, connecting via WiFi, I can connect fine using Filezilla. If, then, I connect over the docking station, I find that DHCP has assigned a different IP address (192.168.0.8), and I have to reconfigure Filezilla all over again. I have tried this without using reserved IP addresses, but cannot get Filezilla to connect at all. If, when wired (or vice versa) I try to force TCP/IP v4 to connect to the IP address that I have reserved over WiFi (or vice versa) DHCP gets all upset, and drives me back to the IP address that it first assigned.
This surely ought to be possible, but I must be missing something - what is it?
