I'm having problems with my Wifi connection.

I did a test on with the following results:

Packet Loss: 0%
Ping: 103ms
Jitter: 29ms

Same test but from another machine on the network resulted in much less numbers for Ping (17ms) and Jitter (1ms). I updated my driver for the wireless card with the latest available.

I'm using Intel Ultimate-N 6300 AGN adapter (Win7/64bit) and D-Link 855L wireless router. WiFi configured for WPA2 N-only connection. I'm also using 'less crowded' channel.

Below is the ping statistics between my machine and the router:

Ping statistics for
    Packets: Sent = 3603, Received = 3535, Lost = 68 (1% loss),
Approximate round trip times in milli-seconds:
    Minimum = 1ms, Maximum = 1746ms, Average = 13ms

Appreciate your help!

much of this is going to be related to environmental conditions like the location of the device relative to the wifi ap (walls, metal/concrete girders), and ambient interference (fluorescent lighting, wall power lines, high power devices). how much do the readings change if you do the test of both devices from the same location? – Frank Thomas May 18 '13 at 19:51
@FrankThomas I tested both computers in front of the router (both computers are laptops) in the same room. – Timka May 18 '13 at 19:59
if they have the same network card and driver then, it must come down to a characteristic of the laptops themselves. – Frank Thomas May 18 '13 at 20:15
What network configuration/hardware does the machine with better performance have? – Nevin Williams May 19 '13 at 3:21
@NevinWilliams Machine with better performance has Intel advanced-N 6250 wireless card (built-in). I also noticed that on my machine I have Dropbox installed and when I pause syncing gives me better results – Timka May 20 '13 at 20:39
