I have a new DAP-1360
talk to Dlink directly. (no main router stated, model?)
it is just a RANGE extender,
7 different modes
Access Point,
Wireless Client,
Bridge, Bridge with AP, Repeater, WISP
Client Router or WISP Repeater
Compatible with 802.11b and 802.11g Devices(no main told)
.
repeater mode (1 of 7) is covered in the manual
and wirlessly bridges to the main AP, and extends the range of the wifi to the new zone,(goal?)
( do this here but use Ethernet from main to new AP) vastly better.
page 26 in your manual covers setup for Repeater mode.
did you do that?
step one is the SSID, use a new name here, not same as other AP or other wireless nodes, ok?
step 2, select repeater
I never use WPS so I skip this (its insecure)
pick manual
page 29 find our main router, SSID name, or survey it.
this is very important to marry the new AP to the old router SSID.
my main would be WPA2, id not use any others (security)
then type in the mains , Password, 8 to 32 chars.
its done.
update the firmware in both routers first? be wise that.
I never do this ,all it does is slow down wifi in 2nd zone.
for sure walls present ! in the line of site paths.
I bridge them with ethernet (wired) now both zone go full speed.
