You should only need to purchase a wireless router, swap it for the old router, run the setup program to secure the wireless router, and then use the wireless setting to connect the laptop.
Thanks for the info - we are complete newbies at this stuff so don't really understand what we are doing.
First step: We did swap the wireless for the wired router and plugged a USB ZyXEL USB wireless adapter into the PC - but the PC could not connect to the Internet. Nor could the laptop find the Internet via the wireless router - as it had before when the the laptop and the wireless were used alone in a different city. Is there some additional step we have to take just to get either working wirelessly in this location with a different DSL provider? Do you have to notify the DSL provider first to make this work? From what we understand, the DSL modem should work (out of the box) for either for wireless or wired, correct?
Should we be able to just plug an Ethernet cable from the PC to the wireless (a Cisco Linksys WHT120N) to use a (faster?) wired connection. Or does this require extensive S/W mods in the Wireless setup? Is it better, once we do get a Internet connection, to use to use the ZyXEL wireless adapter with the PC, or is a wired Ethernet cable connection better?
We did run the setup program to "secure the wireless router", but not sure what you mean by "using the wireless setting to connect the laptop"?
Thanks for your help - greatly appreciated.
