I have Actionec GT784WNV modem/router whick was using WEP. Now I have coverted to WPA, but certain devices (Printer, wifi dongle, etc) cannot connect to computer. Other devices are OK. I can locally connect printer to wifi network using the SSID and WPA 16-character password, but the network cannot connect with the printer. The printer status report on the printer shows good connection. Computer cannot see the printer. Putting the router back to WEP, everything connects just fine. Have tried various fixes with printer, but no success on WPA. The router has firmware version VZ-1.1.22---Is there a new version?
