Is there any way to access my previous addresses?

Using a wireless access point as an AP client

• Connecting with your own wireless access point (AP) to another one that provides access to the Internet -- help me figure out the basics here. My neighbour upstairs owns an AP (it's the http://www.dlink.com/products/?pid=292). He wants to put it in use when his own Internet connection is down, so that he can temporarily browse the Web via other APs in the area that are open to acess (a site survey shows several). Problem is he doesn't know how to do that; I was asked to help -- I can hack my way through wireless routers & static IPs, etc. but wireless access points... I'm not too savy with. I've read the (zipped PDF file) and searched Google for possible set-ups, but I'm still left with lots of questions. I obviously need to set the AP (the "local AP") to "AP Client" mode and point it to another open (un-secured) AP (from hereon referred to as "remote AP"). I guess it would also help if the remote AP served IP addresses automatically (DHCP) -- let's assume that's the case here. On the local AP front, if I'm to enable the "DHCP server" option (so that machines on my side) can get IPs automatically from it, any hints on what the values for "Gateway", "Wins" and "DNS" should be? (http://akil.textdriven.com/uploads/dhcp-server.png) [Note: the local AP also allows me to enable the "DHCP client" option but that would be a no-no, I think, since -- as the http://www.dlink.com/products/support.asp?pid=292&sec=0#quickInstallGuides (zipped PDF file) suggests -- I can only access the AP's configuration page when its IP is set (statically) to "192.168.0.50", the Subnet mask to "255.255.255.0" and my IP (again, statically) to "192.168.0.x". So, "DHCP" client is probably better "disabled" right?] Finally, (assuming again we're dealing with a remote AP that's open to access and serves IP via DHCP) is this how it's supposed to work? i.e. pair the computer with local AP, set it to "AP Client" mode, choose a remote AP and you're done -- you've got access to the Internet. Or am I missing something? (And I can't help but wonder: what happens if the remote AP doesn't serve IP address via DHCP? How do I have to adjust the local AP's settings?) Thanks a ton for reading this far -- and thank you in advance for your help and any clarifications you may have (I'm pretty certain I've got several things wrong in my description above).

• Answer:

  Maybe I'm missing something here, but is there some reason he can't just select one of the other access points from his client machine when he needs to?
