capabilities to your LAN is to replace your wired router with one that has wireless features as well. WAPs work as well in conjunction with wired routers, but are a little more expensive.
I've just used a second wireless router, set to be an access point to extend my wireless networks reach. It's not that hard, just get the settings correct.
I currently have a laptop that gets its IP address on the wired ethernet using DHCP. I will like to be able to do access this wired ethernet remotely -- without physically plugging it into the ethernet jack everytime. An access point will work, but it will need an IP address of its own, in addition to making itself available to others. I looked at wireless-to-ethernet bridges, and all that I could find require an IP address as well.
Conceptually, all I am looking for is an extended long cable, except just that I want to have it wireless. I don't want to change any configuration -- like that required to support DHCP for the WAP etc, nor do I want to make any device I may add available or visible to others. The packets should ideally just be forwarded from the ethernet connection to my wireless card, and vice-versa.
Does anyone have any advice on any specific bridge or device which may do this? Or any way I can do this?
Thanks a lot!
