How Can Dropped Data Packets Be Fixed Within A Wireless Connection?

Hi Everyone;

        I have a wireless computer which seems to have random dropped data packets to the router.  Sometimes I am able to ping to the router without any dropped data packets.  And, on other occasions, there are 25% to 50% lost data packets.  Of course, this creates a domino effect.  Whenever there are dropped data packets from the router, internet pages either load very slowly or not at all.  And, other times, internet connectivity drops all together when participating within online games.  

         Given this problem, I am interested in any strategies for fixing dropped data packets.  Theoretically speaking because I am not sure it can be done practically, is it possible to adjust the "size" of each data packet or block within a key of the registry file?  Or, can the data packet size be manipulated within the router's configuration?  And, if so, would I need to decrease the size of the data packet to help permit a smooth flow of packets to and from the wireless?  The signal strength of the wireless is "excellent", therefore, it does not seem to be the mechanism behind this situation.  

            On a sidenote, I ran the following command: netstat -s -p tcp and noticed the following most important parts:  segments sent.....1142.....segments retransmitted...135.  I am not exactly sure how to interpret this from a technical perspective, but, I do not think this is very good.  

            In closing, I certainly welcome any shared insights to this perplexing WLAN concern.  The OS on the wireless is XP Pro SP2 using a Wireless G Linksys Broadband Router (Model WRT54G).  The wireless adapter is a Linksys Wireless G (Model WUSB54G Ver. 4).  If any more technical specs are needed, please feel free to let me know and I will submit upon request.

            Thanks in advance for any attention given to this question.

Hi There;

          Thank you so much for the very well thought out suggestions to my wireless problem.  I have tried many different things which "temporarily" fixes the weak signal strength, but, I have not found anything yet which consistently keeps the signal strength for the wireless good and stable.  

        I believe I will be trying out network stumbler to determine the channels being used by nearby wireless setups and change our on within the router if need be.

           Thanks again for the help.
