Testing devices with wireless WAN connections

At QA Cafe we continuously see new consumer broadband and home network devices come into the market and into our lab. One of the newest class of devices are “travel routers” - routers that are popular with people who frequently connect to public Wifi networks or those offered by hotels, restaurants, or hospitals. These devices let you preserve network settings that your devices need, let you set up default connections to VPNs or other secure networks, and act as an additional level of firewall security when connecting to public networks.

Testing a Wifi Range Extender or Wifi Mesh System

Devices that enhance consumer Wifi are becoming more and more prevalent, both off the shelf and deployed by service providers. A Wifi booster or Wifi range extender is sometimes a simple repeater, but more often they act as layer 2 bridges, and can still be tested for performance and management via TR-069 or SNMP. Isolating a node in a Wifi mesh When there are multiple repeaters forming a mesh, as is the case with a lot of consumer Wifi systems , it’s best to isolate the DUT that you want by telling CDRouter which BSSID in the mesh to connect to.

What should you test in Wifi mesh enabled routers?

Of all of the things about broadband service that is most keenly felt by the end user, it’s the quality of their Wifi networks. Wifi is unique in that it is a complex networking system that users are aware of, and make purchasing decisions for consumer electronics and for broadband service around it. Realizing this, many companies are building Wifi products that specifically target the consumer rather than relying on the provider to deploy Wifi service, using Wifi mesh technology to deploy quality, reliable Wifi throughout the user’s home or business.

Webinar - Testing Wifi Guest Mode

One of the most common use cases for Wifi is the ability to set up a guest network alongside another network that is used by the home user, business, or other organization. It’s also a source of a lot of problems: guaranteeing that the Wifi router or AP can handle the number of clients connecting; making sure that the security in place for the guest network and other networks works correctly; and ensuring the policies you’ve put in place for guest access vs. Read more...

Testing Wifi Scalability with Wireless Station Virtualization

Nearly every home device has Wifi capability, and with the emergence of the Internet of Things, that number is likely to increase exponentially. It will be more important than ever to ensure that Wifi routers and access points can handle the load and the applications that are likely to be accessed by all of these Wifi enabled devices. CDRouter 9.2 introduced the ability to simulate many wireless stations from a single wlan interface. Read more...

Testing to reduce the big three broadband customer support problems

The most well understood case for product testing is in quality assurance while a home networking product is in development, or testing its integrity between firmware revisions. But testing before, during, and after deployment can also ensure that service providers reduce costly support calls and truck rolls. We asked some of our customers, some in the service provider world and others who develop management and support services for service providers, what the most common causes of service calls are.

How do I create a reliable test setup for wireless testing?

When testing with a wireless interface, the link quality between the access point and the wireless adapter can impact test results. Some test cases are not tolerant of packet loss. Any packets dropped by the access point could lead to a test failure. When purely testing functionality and not the reliability of the over air connection, QA Cafe recommends directly connecting the antenna of the wireless card to the access point antenna using an adapter cable with the appropriate terminations.
