Critically important information for all devices.

The routers above are recommended because they have:

  • A long track record of success with many customers that own these devices that we have worked with extensively.
  • Bandwidth Management/Rate Control, which is a rare feature that is not found on many routers on the market today.  It's effective at ensuring excellent call quality and effective at resolving call quality problems in many cases.
  • Some necessary configuration changes, as is the case with all routers, but they work well after the changes are made.

Feature comparisons are based on the following models:

  1. AirStation™ AC 1750 DD-WRT Router
  2. ZyXEL USG20W
  3. TP Link TL-WR1043ND
  4. Cisco RV042 Hardware Version 3
  5. SoncWall TZ215
