I have a pretty simple setup. All SMC gear consisting of the following gear.
SMC SMC7904BRA Router
SMC SMCWEBT-G Access Point
SMC WPCIT-G 108M Card

All connects and runs ok. However when I check the status under windows networking I find I am getting extreme amounts of errors (see pic below).

I have a WPK2 password set with mac address filtering turned off.
There are a couple of cordless phones in the house but unplugging these makes no difference. There is one other wireless network in range when I scan for networks (and it is on a different channel)
What could be causing these huge number of errors?
