I want to bridge two AP's but they don't find each other.

HOW TO, left off those 2 key words?
Read the manual yet? its free to get and read.
I have AP here too, and access point,
first off we have not a clue as to your homes ISP, your homes SUBLAN, at all ,nor if you have more that one AP access point
this your first?
not router stated, no to what modem and to what ISP
and if the router has a wifi AP also?
on mine I wired the AP 100feet from router using 1 cat5 ethernet cable, nothing works better , in fact on can daisy chain AP points using wired connections. for best speed, for a fact.


your router>>cat5>>>COMfastAP wifi AP to everthing.
using wifi bridge are a PAIN,
1: your router does not support a wifi bridge.
2: the AP (unstated) is too far from the router so all you get is weak signal to the AP and then out the AP same. PAIN max.
because of #1 and 2 we always wire the remote AP wireless first.

spec on yours is (key)
WiFi Standard: IEEE 802.11ac/a/b/g/n

the page is here.

1st google hit no less.
I think they SUX, no real manual
a real manual will show all ways to use bridge mode.
and THEY DONT, so they SUX.

wifi is complex as are bridges. so no manual no buy, no joy.
There are far better products.

if super lucky, and the other wifi AP is close that you are bridging to , it may work easy, per link above (the links is like toy grade instructions IMO)
Rear

Client would be the closest thing to a bridge.

Try Putty and a 9pin male to RJ45 RS232 serial console cable.
the instructions are in the link provided here:

I’m happy to help further over the phone at https://www.6ya.com/expert/matt_7e951e081251ffbc

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.

Solution #1
Set the DWL2000AP+ as "Bridge Mode" and the new AP (DWL2100) in "WDS Mode".
On each device set the MAC address of the other device.

Solution #2
Set the DWL2100 as "WDS with AP Mode" and the DWL2000 in "Bridge Mode".
On each device set the MAC address of the other device.

The first router must the root AP and the second should be set to Wireless Repeater. Follow the steps on how to resolve this setup.

1. Get the Wireless MAC Address of the main router. The router has two MAC addresses, one is wired and 1 is wireless. To determine the wireless MAC address, go to Status page of the router, there's a sub tab there for wireless and you'll see the Wireless MAC Address. Take note of it.

2. Access the setup page of the 2nd router. Change the LAN IP address to 192.168.0.2 then save. Power cycle it by just turning it off for 10 seconds then turn it back on. You can now change it to Wireless Repeater and there's an option for you to type the Wireless MAC address of the main AP. Make sure all wireless settings are the same on both routers like SSID, Channel and Encryption Key. Save your changes after that.

3. From your computer, try to ping the 2nd AP which is 192.168.0.2. If it replied back, you're all set.

Good Luck!

internet from someone elses wireless AP, you will need a wireless bridge.

The first step here is to identify exactly what portion of the link is the culprit. Clearly you must have some sort of AP in the remote building for the handheld devices to connect to, since the bridge radio won't perform that function. So I would attach an AP of that type directly to the ProCurve and see if the problem is present or absent when you try to sync devices using that AP without any involvement by the Engenius units at all. If you isolate the behavior to the Engenius units, you may have to play with the Data Rate and Fragment Threshold settings.

1. Use a straight-through cable with 9-pin male to 9-pin female connectors to connect the COM 1 or COM 2 port on your computer to the RS232 port on the bridge or AP. You can select the Reset option only through the console port.
   
2. Open a terminal-emulation program on your computer.
   Note: These instructions describe HyperTeminal; other programs are similar.
   
3. In the Connection Description window, enter a name and select an icon for the connection and click OK.
   
4. In the Connect To window, select the port to which the cable is connected and click OK.
   

1. In the Port Settings window, enter the following settings:
2. 9600 baud
   

• 8 data bits
  
• No parity
  
• 1 stop bit, and
  
• Xon/Xoff flow control
  

1. Click OK and press Enter.
   
2. When the Main Menu screen appears, reboot the bridge or AP by turning the unit off and then turning it back on.

12. Type yes and press Enter to confirm the command.
    Note: The Reset command is valid for only two minutes immediately after the bridge or AP reboots. If you do not enter and confirm the Reset command during that two minutes, reboot the bridge or AP again.

I have solved the problem:
- first, I had to change the management address in CF-WFAP into address that could be recognized by the router (i used 192.168.1.2),
- DHCP turned off, and set default gateway and DNS to 192.168.1.1. as in router, computer IP was set to 192.168.1.xxx, push "apply", change web address to new one,
- set AP mode to station-infrastructure, push "apply" buton to restart AP,
- set security to same security as in router and copy key into proper field, push "apply" again to reset the AP
- finaly check wireless station around and choose the router (same encription)
