I have a feeling that this will not work but not entirely sure why. I work with an existing network of around 30 PCs. I trying to see if I can attach a wireless router to my network output in order to create a subnetwork to attach my laptop as well. Now I suspect this may not work as we are using internal IPs 192.168 etc, with mine being 192.168.0.25 (although I think this is not a static IP!). Am I right in thinking I probably cannot create a subnet as Im already on my systems subnet? Im not sure of the physical layout (and nor does anyone who works here, they get a freelancer in to help) so that doesnt help me. Any thoughts? Cheers.

Does the wireless network actually have to be on its own subnet (e.g. different IP address range)? Or do you just need to allow wireless connections to your existing network as-is? Either way you need to do pretty much the same thing - add a wireless access point. This can be something as simple as a wireless broadband router. If you do require another subnet, you might also want to install a "real" router to handle communication betweek the two networks. If you don't require another subnet, you likely won't have to do anything other than plug in, configure, and secure the wireless access point.

doesn't sound like you need to subnet. you do have to turn off dhcp on the router though. set the lan side of the router to a static but available ip address on your present network. Put that ip address in as an additional gateway in your pc and you are off and running.

Ahhh I see. Yes it was more adding wireless connectivity to an existing LAN. (something I was told wasn't possible due to lack of nodes... which I find very hard to believe) My concern was that adding a router would force me to use its DHCP and therefore a subnet. How do I find out which IP addresses are available for a fixed IP? or is this something Im gonna have to go to the source for? Thanks for your help.

Given that you are using a 192.168.x.x IP address range, you most likely have 254 addresses available. Your subnet mask is 255.255.255.0, right? Any of those IP addresses are available for use as fixed addresses, as long as you exclude them in your router. This is simple - just consult the manual, or click around in the router's admin interface until you find the "exclude IP addresses" option. >>My concern was that adding a router would force me to use its DHCP and therefore a subnet Turn off DHCP in the wireless router. Problem solved. Also, be sure to connect the new router to your existing network via a LAN (as opposed to WAN) port, or you will be using it as a router. You don't want to do this, as it adds needless complexity. Also, keep in mind that you can use an access point, rather than a router, to gain wireless connectivity. This might actually be more expensive though, considering the extremely low cost of little broadband routers these days.
