Linksys Wireless-G not connecting to internet
Make sure you are plugging the SMC into the WAN port on the Linksys router and not the LAN ports. Your internet connection (which is your SMC) should always plug into your WAN port on the Linksys. Any computers that you may need to plug in, like Desktops that are "wired" and not "wireless", should plug into the LAN ports on the Linksys. If you are not using the WAN port on the Linksys for your SMC modem, then that would explain why you cannot get to the internet on wireless or wired computers.
Here's why you are getting the "low connectivity" message:
Computers don't understand why the Internet is connecting or not connecting...so the "low connectivity" message you keep receiving has nothing to do with your wireless signal strength. To a computer NIC, "low connectivity" means your network adapter could not find a DHCP server and receive a valid IP address. When this happens, your network adapter assigns an IP address to your computer in the following range...169.254.0.0, and will display the "low connectivity" message until it is able to receive a valid private IP address from the DHCP server. You can verify this by going to START | RUN and typing "cmd" (without the quotes), then hit ENTER. A black box will pop up....then type "ipconfig" (without the quotes) and hit ENTER. This will show you your IP address, subnet mask, and gateway address, and you can verify that your IP address is in the 169.254.0.0 range. A valid private IP address is typically in the 192.168.0.0 range, but could also be in the 10.0.0.0 range, or the 172.16.31.0 range.
Also, make sure you have DHCP server enabled on the Linksys router for the LAN. This will ensure your "wired" and "wireless" computers receive a valid IP address.
The WAN port on your Linksys router should be configured to "Obtain an IP address automatically using DHCP".
