Hello, this link you can find all your answers they explein step for step.

Can't use a router as a repeater in a wireless sense. You could set it to AP mode and run an ethernet cable from a lan port on your other router to the WAN/uplink port on the Zyxel. If it doesn't have AP mode then you could have it in gateway mode run have a different subnet on the Zyxel with DHCP.

ECB3500 Can I downgrade firmware safely with this product?Yes. I cannot get into the device from my computer. What is the basic setting check?

- Make sure you are directly connected to the unit.
- Do not have a switch or router in between and do not connect wirelessly.  
- Make sure your power injector/adapter is on, power is going to the unit, and the "network" side is going to your computer.  
- Make sure your computer is set to a static IP address of 192.168.1.10.
- Type in 192.168.1.1 using Internet Explorer.

How to change the IP Address?

The default IP address is 192.168.1.1. This IP address is typically in conflict with many routers out in the market. You will need to change the IP address manually to an IP address that is different but part of the same network. This means if your router IP address is 192.168.1.1, you should change the device to 192.168.1.2, for example. We recommend you change the IP address before other settings. You change your IP address in the "LAN" section in the GUI.

How do I reset the device?

Locate the reset button next to the CAT5 (RJ45) connection. Press and hold the reset button for 10 seconds and then let go. You should see your 10/100 LAN connection at your computer go away and then come back. That will confirm a reset has occurred. The unit settings should all be back to default including its IP address of 192.168.1.1.

How do I set up AP WDS Repeater?

How do I set up the device under Apple MAC OS X environment?

Click here for instructions.

I cannot connect or maintain a log in to the device.

We recommend using internet explorer with at least IE7 or higher. Make sure you have latest version of Java script.

What distance in kilometers (km) should I set the device to?

Default is 1km. If you are setting up long distance point to point links, the time it takes the radio wave to get there needs to be considered for proper handshaking (ACK response). This window should be accurate within 5 kilometers. In other words if you have a 5 kilometer link, ideally you should set it to 5km, but a setting of 1km to 10km should keep you in an acceptable window. For short distances, keep this to 1km.

What is a point-to-point link setup?One unit would need to be in AP mode while the other in CB mode. The AP should be connected directly to the routers LAN port, and the other will be in Client Bridge Mode linking back to the AP. The Client side will then provide a WIRED connection for users of the remote location. You can choose to connect this wired connection to just one PC, or to a switch, hub, or another wireless access point for multiple users at the remote location. What is a Client Bridge (CB) Mode?

A client connects to an access point. Your laptop is a client. A bridge is something that connects two "wired" networks together. A client bridge therefore is a radio that wirelessly bridges two networks. The Ethernet port of the 2610 in CB mode provides the wired connection to the remote location. This Ethernet port can directly connect to a single PC, a hub, a switch, or another router. 

What is considered a "good" signal?The signal meter is not available in AP mode. In CB mode, under connection status, a signal of -74dbm or better is a good signal. It's important to understand which direction numerically is a better signal. Dbm's are referenced to 1 milliwatt. 1mW = 0dbm. A stronger signal would be a positive number and a weak signal would be a very negative number. For example, a -50dbm signal is stronger signal than -92dbm. What is spanning tree protocol?

When there are several possible paths a packet can route to (redundant links for increased reliability for example), a loop can occur (jamming up the network). It is used to prevent these loops.

What is the default gateway?The default gateway is your router's IP address. The default gateway information is not required, but is recommended.What is the default user name and password to log into this device?

Log in name is "admin" and password is "admin" by default.

What is WDS Mode?Stands for Wireless Distribution System. Allows access points to link together and provide repeating. Note however, this repeating comes at a cost of reduced bandwidth. Bandwidth will be reduced by 30-40%, and it is recommended that NO multiple repeating hops be done for this reason. Which antenna connector is the primary antenna?The one closer to the power jack.

Use AP mode ; but may really have some compatiblity issues though... Good Luck*

check your wi fi is enabled on ap settigns also che k broad cast ssid is enabled on it.

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)

Are you trying to setup both access point to repeat the signal of the router?
The correct way to setup the AP's as repeater is to access the setup page of your router go to status and go to the wireless subtab, check what is the MAC address that is what your suppose to configure on the AP's not the LAN MAC address which is on the local networks subtab on status.
Access the setup page of the AP's and go to AP Mode, make sure that you choose the repeater and copy down the Wireless MAC address you obtained from the wireless router. To enable roaming, meaning your wireless computer/device will connect to the AP/router closest to its location, change the wireless channel on all three device for example WRT54G will be on channel 1, 1st AP as repeater on Channel 6 and the last AP to Channel 11 but the other settings must be the same(Wireless name(SSID) and Wireless Security).

Note: Setting up an AP as repeater to repeat or extend the signal of another AP that is set to repeater is not recommended since the signal will deteriorate due to the number of hops the packets will be sent.

Hope this will help you setting up those WAP's which for me is quite useful since you can set it up to act as a repeater, AP client and a bridge to a WRT54G router.

Regards,

you make a device into ap mode you can get it

If you default the unit, does it still reboot?

If so, it looks like the unit is faultly.

If not, you might have a IP conflict, or channel problem. Check the two units are on the same channel, but have differant IP address.
