I am using an SMC SMC2804WBRP-G Barricade g Wireless Broadband Router with Built-in USB Print Server.
My Internet connection is cable with a Motorola Surfboard modem connected to this router. My desktop computer is connected to one of the Ethernet ports on the router and my printer is connected to the USB port on the router.
I use a laptop around the house and, normally, the laptop connects to the router and I can print wirelessly from the laptop, through the router, to the printer. I use WEP 64-bit with an encryption key.
For the past couple of weeks, I have not been able to connect to the SMC wireless router. It shows up on the wireless network list on the laptop. When I try to connect, it asks for the encryption key then connects but the network list says "Limited or No Connectivity."
I have tried everything I know -- rebooting the router; pull the power on the router and restart; reset router to factory defaults; refresh the network list; installed updated firmware; move the laptop so it's sitting right next to the router -- nothing works -- still get the "limited or no connectivity" error.
When I tell WindowsXP to repair the connection, it goes through the steps -- disabling the notebook wireless adapter; enable the notebook wireless adapter; tries to obtain new IP address; never does obtain a valid IP address, tells me to contact my system administrator. I am it.
I live in an apartment complex where several of my neighbors have unsecured wireless networks -- I can connect to any one of them I want to -- in fact, I just tried the laptop and connected to four of them with no problem. Recently went on a long road trip and connected flawlessly to wireless networks in every motel where I stayed.
