Signal Status, In Status page, it can show remote bridge Signal Strength for local bridge (Local RSSI) and local
bridge Signal Strength for remote bridge (Remote RSSI). We can decide the best direction of antenna from
following steps:
1. We check the Local RSSI only in one side. (We call it local side.)
2. Fix remote side antenna, and adjust local side antenna. In local side, check the “Local RSSI” first, to
find a best Local RSSI and then fix the local antenna.

3. Adjust the Remote antenna, to find the Best Remote RSSI, and then fix the remote antenna.
4. If “Local RSSI” is changed, and worse than before, adjust local antenna again to get a best one and fix
local antenna.
5. If “Remote RSSI” is changed and worse, adjust remote antenna again.
6. Follow the same ways to get a better Local RSSI and Remote RSSI value. And Fix both side antennas.

Chapter 5 Management
Change Password
Change Password
You can use the Change Password page to change the Bridge administrator's password for
accessing the Settings pages.
To change the password, Type the old password. The default password for the Bridge is:
password. Type a new password and type it again in the Repeat New Password box to confirm it.
Click Apply to have the password changed or click Cancel to keep the current password.
Remote Management
Remote Management
Bridge supports SNMP. If you use SNMP to control bridge. At first you should set SNMP settings
The KW50-O8500 supports CLI too , which could be accessed by Secure Shell (SSH). It is recommended PuTTY
be used to login.
Once the program is downloaded, open up by double-clicking. Note that before using PuTTY, be sure you are able
to connect to the MIMO WiTDM bridge.
1. Active Secure Shell(SSH). By SSH instruction setting the bridge.

Chapter 6 Troubleshooting
FAQ
Q1：How to know the MAC address of the Bridge?
The MAC address is written in a label which is in the bottom of Bridge.
From the General page of WEB configuration, you also can get the MAC address of the Bridge.
Q2：Why two Bridges can not build connection after setting?
1. Check “Operating Mode”, one of bridges is Base Station, another one is CPE.
2. Check “Channel / Frequency” whether is same.
3. Check “Date Encryption” and “Key” whether is same.
Q3：How to adjust output power?
In the Wireless Settings page, you can do it.
Q4：The wireless becomes unstable such as ping timed out and lose pack after a period of well
work?
This situation may the wireless network is disturbed by something, what you can so is
following steps:
1. Check whether every joint point of network is well ( such as Ethernet port, antenna connection. )
2. Change the channel if the Link Test value is not high, excluding other wireless equipment disturb
the Bridge.
3. Restart the Bridge.
4. Default the Bridge and restore last settings.
5. Check the wireless port and Ethernet port environment and virus exist or not.
6. Please call the sales if can not solve problem after all.
Q5：Why can not open WEB page of remote wireless device in local network?
Because this kind of settings will slow the response of remote AP WEB Server, just waiting for several
minutes or restarting remote wireless bridge is a way to solve problem. We suggest you set the Bridge in
local wired Ethernet network.
