the problem is the age difference between the pronto and your newer routers. A lot of the old security like whats used on the Pronto are no longer used. So you have a few options. Using a non secured WIFI and turn off the SSID and hope no one else finds out. How comfortable you are using this all depends on your level of paranoia. LOL. Second is to pick up an older router and or WIFI extender that still uses WEP. This what I did. I am not home right now, but I had an old WIFI Extender and it has worked with out any issues.
