Wireless connection dropping out alot

My wireless connection (which goes through a router) constantly drops out. I am using Vista Ultimate 32-bit.

It is definitely not the router that is causing the problem because there are 3 other PC's that connect to the router and their wireless connection is perfect. Also, the router (Netgear) has the latest drivers.

I have ping'ed the Default Gateway that my notebook is using and it sometimes comes up with the following response:

ping xxx.xxx.x.x (xxx.xxx.x.x is the default gateway)

Pinging xxx.xxx.x.x with 32 bytes of data:

Reply from xxx.xxx.x.x: bytes=32 time=41ms TTL=64
Reply from xxx.xxx.x.x: bytes=32 time=1ms TTL=64
Reply from xxx.xxx.x.x: bytes=32 time=73ms TTL=64
Reply from xxx.xxx.x.x: bytes=32 time=2ms TTL=64

Ping statistics for xxx.xxx.x.x:
Packets: Sent-4, Received=4, Lost=0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum=1ms, maximum=73ms, Average=29ms

Sometimes in the ping statistics, one of the "Reply from....." lines says "General Failure" or "Request timed out", which in turn results in 1 Lost Packet.

What does this all mean ? Please help.....

I have been trying to fix the wireless connection on my notebook for about a week and have wasted nearly 10 hours trying to fix it.
