Try changing the 'Channel' on the wireless broadcast. Might be catching interference that is dropping your signal for brief periods.
Move it at least 2 points away from where it is now.
Also, you may have set a password, but if the SSID is still broadcasting I can almost guarantee that it's a matter of when, not if, someone will break your key. Make sure and turn that SSID broadcast off.
Try changing the channel to 1 or 11, they are the least used channels.
As for SSID broadcast, it doesn't matter at ALL if it is broadcasting or not. If someone wants in, they will get in. All that turning off SSID broadcasting does, is when it sends out a signal, it says "hey I'm not broadcasting, don't show me please."
Normal clients respect it, and it remains hidden.
To someone trying to find a wireless to get into, they wouldn't even notice if its broadcasting or not, they would see it, and crack it within 2 minutes (for a 128bit key)
To answer your original question - ping.
on Windows.. open up Command Prompt and type:
ping /t google.com it will send an echo request a second until you stop it with CTRL+C, then it will display results.
This is my results from Linux, so it might be a bit different than yours.
--- google.com ping statistics ---
6 packets transmitted, 6 received, 0% packet loss, time 5003ms
rtt min/avg/max/mdev = 79.005/79.754/81.063/0.716 ms
0% packet loss = good
I'm not sure if windows has the min/avg/max/mdev but if it does, you would want the numbers to be anywhere from 0-90, and the mdev to be as low as possible
If there is packets being lost, it would require a bit more investigation into the cause, post your results of a ping test, leave it on for an hour or two.
