changing channels

I have a standalone 802.11g access point/router (not my choice to make it standalone but it’s connected to a cable modem in room next to PC-no other outlet)communicating with a 802.11g PCI adapter. It has intermittent connections, especially when I reboot the PC.

After awhile it will finally connect to the internet. Once I reboot it, again it doesn’t connect until I use the (Linksys) utilities it came with… ie. “refresh”, “connect”.

Could this have something to do with the channels? I’ve changed them, and still no luck.
