I've read the similar question on wireless connections dropping, but no answer seems to apply to my case
I have configured the wi-fi lan of my router to broadcast sid and use WPA-PSK. Every few minutes my wi-fi connection drops for a few seconds and then restores.
When I use two computers and run a ping -n 50000 on both computers, I see that the connection drops at different times but with almost the same rate.
the router is a zyxel, one pc runs windws vista and uses a USB wi-fi device from Belkin: F6D4050 the other one runs windows 7 is a Dell PC with an Intel(R) WiFi Link 5100 AGN
there are no other wi-fi lans around
I've tried to change channel. Nothing changed.
I've opend the wi-fi (removed WPA-PSK and encryption) and the connection was stable.
I've upgraded the router firmware to the latest version, but enabling WPA-PSK continues to show a connection loss every few minutes.
Next step is timing intervals to see if there is any relationship with WPA-PSK parameters.
By the way: the router is a Zyxel P-660HW-D1 and the firmare version is
