Testing Hurdles of Wi-Fi APs and Wi-Fi Mesh Nodes

The rapid expansion of Wi-Fi as the medium of choice for home networking has introduced an explosion of new products from both new and established manufacturers. If you’re a developer or QA testing looking to prove your implementation works, or a service provider testing before deployment, you’ve probably learned that testing Wi-Fi involves more than just physical and MAC layer performance and interoperability. What else should you test to ensure that your devices will work well in the real world? Read more...

Testing Cloud Managed Routers and WiFi Multi-APs

Incumbent vendors and startups are developing “smart” home routers, WiFi access points, or parental control systems that are meant to be managed using a web based application in the cloud. This presents some difficulties for network function QA, as it is difficult to ensure a controlled environment when your device needs to be connected to the Internet or other external resources. What do we mean by “cloud managed”? Read more...

The need for automated CPE testing (and a CDRouter controlled robot)

We had the opportunity to speak with Steen Garbers Enevoldsen, head of Net Research and Development at Fullrate, and blogger, columnist and youtuber in his spare time. Fullrate is a service provider in Denmark who uses of CDRouter for their CPE testing. We’ve known Steen in the industry for a long time. He knows a lot about Wi-Fi and networking in general, and he’s certainly a CDRouter “power-user”. Just how much of a power-user? Read more...

Does your device correctly configure Wi-Fi using TR-069?

Testing a TR-069 Wi-Fi setup One of the most important use cases of TR-069 (and its evolution protocol, USP) is in the autoconfiguration, management, and troubleshooting of Wi-Fi networks. Often the source of the most customer service problems, being able to set up an end user’s Wi-Fi and make sure it’s working is critical for a satisfactory “carrier grade” home network. TR-069 testing often revolves around ensuring the conformance of a device’s CWMP stack to the protocol specification, including the tests that provide certification metrics as part of the Broadband Forum’s official TR-069 certification program.

How do you test TR-069 enabled devices?

If you’re developing a device or deployment that uses the CPE WAN Management Protocol (TR-069), like managed Wifi or other services, what should you test for? What are the benefits of automating it with a dedicated test platform? What are the benefits of getting certified or asking your vendors to certify? Basic components of TR-069 If you’ve been through our TR-069 training series, you’ve seen an in-depth look at all of the pieces that make CWMP work. Read more...

Testing Wifi Association Behavior

Wifi delays have a big effect on user experience Delays from Wifi are one of the biggest reasons why end users end up having a bad experience when trying to use the network. In addition to the latency caused by retransmissions, the speed at which devices associate and re-associate is a factor that is mostly unseen by the end user but can result in serious frustration. Testing Wifi association behavior is one of the most basic metrics to gain about your DUT at this layer. Read more...

What should you look for when testing broadband CPE or Wifi performance?

If you are developing or deploying broadband CPE, routers, or Wifi devices, what are the things you should look for when testing performance? Hint - it's more than just throughput, and having a fully automated system to exercise the entire system is key to ensuring true performance. What is performance testing? What do we mean when we talk about performance testing on a broadband gateway or access point? Read more...

Automated home gateway security testing

Test your devices before attackers do. It’s no question now - malicious attackers are targeting the home network, and the gateway in particular. Testing for security vulnerabilities can be tedious and ineffective if you don’t have a controlled, repeatable, and fully automated test environment. Join the CDRouter team as we show you: How to test the functional performance of your security tools like parental controls, firewalls, and the security of your user interfaces. Read more...

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. Read more...

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.

Smallnetbuilder uses CDRouter for tests and ranking

The popular review and ranking website for home networking, Wifi, NAS, and other connected consumer devices, smallnetbuilder.com, has revamped its test procedures and will be adding a host of functional, scaling, and performance test cases exclusive to CDRouter to measure and rank the quality of small network equipment: “We’ll be checking DNS, DHCP, UPnP, NAT, firewall and many other routing functions on every router we review. As far as I know, this will make SmallNetBuilder the first publication to perform exhaustive and consistent functional router testing. Read more...

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...

Exploring scaling tests - Is your home gateway IoT ready?

By now we’ve all heard of the coming flood of network aware devices collectively referred to as the “Internet of Things”. While the term encompasses a wide variety of use cases that are not all clearly defined, we can come up with some rudimentary expectations on how this influx of connections will affect networks. For the home gateway, the most significant impact is how to handle an order of magnitude more connections than most are traditionally designed for - how well does it scale? 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.
