Check out the Troubleshooting Sequence
1. The light on the POE power supply is blinking
- When the light is blinking it means the output of the POE power supply is shorted. Check the cables plugged into the POE power supply. The RJ45 Jack that is next to the AC Power Cord should be going to the computer or switch or hub or router or game console or network device. The RJ45 Jack on the other end of the POE unit should be connected to the Q-Bridge.
- If the light is intermittent in that it sometimes is steady and sometimes is blinking when the power is turned on, then the POE power supply is most likely defective.

2. My Browser won’t load the JavaScript menu on the left side of screen
- Your browser security settings won’t allow javascript loading. In your browser go to TOOLS | Internet Options | Security TAB, then click on Default Level (should change to medium level), then click on APPLY and close the window. Close your browser and try accessing the Q-Bridge again.

3. I cannot access the unit anymore after doing a Reset to Factory Defaults
- After Reset to factory defaults the unit will go back to its factory settings. IP address will be either 192.168.1.220 or 192.168.1.221.
- If the power is disrupted during a reset to factory defaults, it’s possible for the unit’s memory to become garbled. If this happens after a reset to factory defaults and the unit can no longer be accessed via the default IP address (192.168.1.220 and 192.168.1.221) then the unit will need to be returned to the factory for repair.

4. When I use antenna alignment mode the RSSI and/or SQ readings are Zero
- In order for the antenna alignment function to work properly, BOTH Q-Bridge antennas must be connected to an active Ethernet segment. This means that both units must be plugged into a computer, a router, a switch, a hub or a game console. All equipment must be powered up. SSID broadcast must be enabled and SSID set to “Connex”.
- We don’t recommend using antenna alignment mode because it is confusing to the novice user and because the antennas are so easy to align just by pointing them in the general direction of the other unit. If “Broadcast SSID” is enabled you can get signal level information from doing a site survey.

5. I experience intermittent problems with throughput performance
- Disable “Broadcast SSID” in the Advanced Wireless Settings. When SSID broadcast is enabled, it’s possible that other wireless devices will try to associate with the Q-Bridge. If this happens, the Q-Bridge performance will be reduced. By disabling the SSID Broadcast, the Q-Bridge will become invisible to other wireless devices.
Note: Disabling Broadcast SSID will also cause the Q-Bridge not to show up in a site survey.
- Intermittent performance problems can also be caused by a strong RF interference source in close proximity to the Q-Bridge. Try changing the channel that you are operating on to avoid the interference. Remember that both Q-Bridge units must be on the same channel in order to communicate.
- Try disabling 802.1d Spanning Tree on the TCP/IP Settings Page

6. Everything was working fine and then stopped working after I changed the IP address.
- If the IP address is changed but the watchdog timer is not setup with the new address, the watchdog timer will reset the unit about every 5 minutes (depending on the setting of the watchdog timer).
- It is best to disable the watchdog timer first, before changing the IP address. Then after the IP addresses are changed successfully the watchdog timer can be setup properly with the new IP address and then re-enabled.
- The purpose of the watchdog timer is to reset the unit if there is any repeated communications error between the units. Most times the reset of a unit will resolve any weird problems it might encounter. The watchdog timer isn’t necessary in the majority of installations and can be left disabled.

7. I can’t get the Q-Bridge to work after making some changes to the Q-Bridge settings
- If you can still communicate with the Q-Bridge units go in and click on Factory Defaults to reset the units to factory defaults.
- Be sure not to interrupt power during this process (1 minute) or the Q-Bridge firmware may get scrambled

8. Last Resort: I tried everything but still can’t get the Q-Bridge to work after I made some changes to the Q-Bridge settings
- Remove all the screws to open up the Q-Bridge unit. Connect the unit to power through the Ethernet cable and allow the unit to boot up, approx 1.5 minutes. Then press the button on the side of the PCB near the LED’s and hold for 15 seconds. This will reset the unit to factory defaults.
- You will need to do this procedure to each unit so that they are both reset to factory defaults.
- Make sure to re-assemble the units as they were before dis-assembly

Trouble Shooting Sequence
Windows XP – Assumes Q-Bridge is in factory default state
1. The basic troubleshooting sequence is:
a. Check power and connections, especially the CAT5 connection on the back of the Q-Bridge.
b. Isolate the Q-Bridge from the other network components if possible. Hook directly to computer using the red crossover cable.
c. Check Ethernet operation by pinging the local Q-Bridge at both the local and remote site. Pinging of local units on both sides of the link proves the Ethernet side is good.
d. Check link operation by pinging the remote unit from the local site. This should be done on both sides of the link. Successful pinging of remote units proves the RF link is good.
e. After you’re convinced that the Ethernet side and RF side is good then start adding back in your network components. Your problem is most likely due to some issue with your network components. Contact the manufacturer of those components for help in setting them up properly. We’ve found that by powering down and restarting all network components fixes 90% of all problems. Turn off Q-Bridge and all routers, switches and modems. Power back up in this sequence: Q-Bridge, Switch, Modem, Router.
2. Some detailed troubleshooting if you can’t communicate with Q-Bridge:
a. Check all power and CAT5 connections, especially connection on the outside of the Q-Bridge unit. Was the RJ45 connector release tab cut before plugging into the jack?
b. It’s best to remove all network components from the situation and hook the computer directly to the Q-Bridge unit through the power supply. Use the red crossover cable when connecting direct between computer and Q-Bridge
c. Check IP address of computer. Go to command prompt (under accessories) and type “ipconfig”. IP Address should be 192.168.1.something
i. If not then go to Network Neighborhood | Network Connections. Select the active connection, click on Properties, Internet Protocol (TCP/IP), Properties, Alternate Configuration Tab, User Configured, enter 192.168.1.222 in IP address, enter 255.255.255.0 in the Subnet Mask. Don’t worry about other settings.
ii. Reboot Computer
iii. Check IP address again. Should be 192.168.1.something
d. Setup a continual ping to the local unit using START | RUN | ping –t 192.168.1.220 (or 221 if that is the local unit). The unit should respond continually. Local unit ping times are typically under 2ms. Keep this window open on your computer so you can see that the unit is alive.
e. The ping test confirms that the Ethernet connection to the local unit is good and working properly.
f. Now ping the remote unit using the same method described above. Typical ping times to the remote unit are less than 15ms.
i. If you can ping the remote unit, then you know the Q-Bridge RF link is working. You can monitor the link over some time period by keeping the ping windows open on your computer until you are satisfied that you have a good solid working link.
ii. If the remote unit doesn’t respond to a ping then you need to go to the remote site and troubleshoot that unit, just like you did on the local site.
