Wifi of D-link modem disconnects every 5 minutes

[luv2break]

hello...
i have connected two dsl modems for extending wifi coverage,the main one is netgear and the extended on is D-link,but the problem is the d-links wireless disconnects every 5 minutes or so..i have connected a pc with a cable from this modem but there r no problems with pc internet...so is the hardware of modem faulty or is this due to inappropriate settings of modem,i have disabled the dhcp and changed the ip address already..Thanks in advance

you cannot use two dsl modems on the same dsl line. if you need to extend your wifi coverage you simply need to get a repeater.

I am not sure what exactly u mean,but i have extended the internet by connecting the dlink modem to the netgear modem,and the net gear modem is directly connected to the main router.
everything is working fine,just the wireless of dlink is getting disconnected for about 10 secs after every 5 minutes.
