"A High-Speed Mode Wireless G Notebook Network Card TO MY LAPTOP"
Your router is a standard 802.11g model. What is the make and model number of your Notebook Network card?
My 1st thought is that it is a non-standard G, due to the marketing "High-speed" label.
My 2nd thought is that there are numerous other wireless networks causing interference.
If your router's configuration has something called "Protected Mode", that is supposed to help.
In addition, try changing the channel number which the router using; e.g. avoid channel 11 & 1 to start with.
P/S Try not to use UPPER CASE ~ its difficult to read and its the equivalent of SHOUTING in an internet forum.
