Why does my Cube's wireless connection seem slow and/or cause frequent break ups? – Teradek

The 2.4 & 5 GHz frequency ranges used by the Wi-Fi versions of the Cube (note: x20 series only had 2.4 GHz) share wireless bandwidth that is also available to other 802.11b/g/n wireless networks; this same frequency range can also receive interference from microwave ovens, fluorescent lighting, cordless phones, and other devices that operate in the 2.4 or 5 GHz spectrum.

To help determine if other wireless networks might be interfering, you can use a Wi-Fi scanning program:

Mac: WiFi Explorer (commercial); iStumbler with the Spectrum Widget or NetSpot
Windows: inSSIDer
Android: Amped Wireless Wi-Fi Analytics Tool or farproc WiFi Analyzer.

Ideally, you should select a 5 GHz channel if your equipment supports it as less equipment resides in that range. When using 2.4 GHz try selecting channels 1, 6, or 11 for your wireless network assuming the channel selected is not being used by other wireless networks in the area. These tools will help visualize and reduce the amount of overlap from outside wireless networks.

Many common building construction materials can reduce or block wireless signals, so having a clear line of sight between the Cube and the receiving system will improve the wireless signal. Additional examples of interference sources are described in this support article from Apple and this FAQ from Cisco as just a few examples

If your setup includes multiple obstructions or wireless networks, Teradek recommends that you consult with a networking professional so that your network infrastructure is configured for best results.
