Signal Dropout with Wireless Card

[Mempho]

My laptop is a Dell Lat D600 and it does not have an internal wireless card. Rather, I have a Linksys card that goes in the slot. I have a problem, however. Every now and then (at least 2-5 times every 5 hours) my card loses its connection with the hub. The quickest way to fix this is to pull the card out and slide it back in quickly. This, of course, can be quite an annoyance playing online poker (especially when I'm playing several tables). This delay, however is quite annoying and has cost me two pots (one flopped set and one flopped 2 pair). It also causes me to "get behind" during multitabling and make several really quick decisions (which sometimes causes me to make an error).

Is there any way to fix this "signal dropout?"
