Wireless link speeds and throughput are low

The Control Channel in Wireless > Radio is set to Auto by default.  It automatically changes the Wi-Fi Control Channel to the best channel.  However, here are some useful suggestions:

  • Move your 2.4 GHz Phone: Move or relocate your 2.4 GHz cordless phones away from the Ubee device. Cordless phones can operate in the same frequency range as your device and cause interference.
  • Re-position the Wireless Gateway: Position your Ubee Gateway at a higher location. Avoid obstructions that can reduce or reflect the wireless signal.
  • Check the Receive Signal Strength easily using the RSSI indicator in the Ubee Gateway Web UI as follows:
  1. Log in to the Web UI wirelessly so you can move around your room (see the “How do I log into the modem's Web User Interface?” FAQ).
  2. Click on the Wireless tab in the main menu.
  3. Click on Access Control on the left side menu.
  4. Scroll to the bottom to see the Connected Clients list. Find your wireless device and check the RSSI. Make sure it is between 0 and -64 for best performance and highest link speed.
  5. Move your wireless device (SmartPhone, laptop, etc.) a few feet from the Wireless Gateway and refresh the Web UI page so that the Age(s) is 0. The RSSI should be between 0 and -64, and link speed should be optimal, based on your device’s wireless adapter.
  6. Move 20 or more feet away from the Wireless Gateway. Stop, refresh the screen, and note the RSSI value. As long as you are between 0 and -64, you should see optimal link speeds. Once you move into the -70, -80 and -90 ranges, your link speeds as seen on your Wireless Client Application will progressively drop until you lose connectivity.
  7. Use this technique to find the optimum position for your Wireless Gateway and your Wireless device.

Note: Double pane, reflective windows and metal ducts reflect signals, and walls absorb signals. When possible, try to position your PC in a line of sight to the Ubee Wireless Gateway to ensure the best signal level. Check Radio settings – 802.11n Mode is required to achieve higher speeds!

NOTE: Be sure that your device supports 802.11n mode. 

  • For Windows 7 or 8 OS:  Go to the Control Panel, click on Device Manager, and click on Network adapters, right click at your Intel® wireless adaptor and select Properties.  Verify it supports 802.11n, as seen below:
  • For Mac OS:  Go to the Apple menu, click on About this Mac, click the More Info button, then click the System Report button. Under the Network menu on the left, click WiFi. Under Interfaces check for “Supported PHY Modes” and to the right you will see the modes supported by your Mac computer.

Your range depends on attenuation (reduction in the strength of a signal).  Here are some TIPS and TRICKS:

If your device has an external antenna, be sure it is screwed in properly.  Antenna VERTICAL provides the best HORIZONTAL coverage.  Antenna HORIZONTAL provides the best VERTICAL coverage.  For internal Antenna configurations, installing your modem in the Vertical position usually offers the best wireless coverage, but test RSSI as shown above to be sure.

Keep the Wireless Gateway off of the floor.  Don’t block (attenuate or reflect) the signal by putting metal around the antenna.  Metal reflects and walls absorb the signal.  Also, make sure that your wireless gateway is installed upright, in a standing position, as stated in the label in the back panel with the #arrow, above the RF connector.  Positioning your gateway horizontally on its side or upside down affects its wireless performance dramatically because the internal antennas won’t be able to propagate the signal as designed.
