Eva emphasizes the importance of a strong foundation in networking basics, such as DHCP, DNS, and spanning tree, to effectively troubleshoot Wi-Fi problems. She also discusses the need to stay adaptable and continuously learn new protocols and features to succeed in the fast-paced world of networking.

The discussion shifts to the importance of continuous learning and adaptation in consulting. Eva, Rowell, and François explore the concept of “learning how to learn,” a critical skill for consultants who need to stay on top of evolving technologies. They also discuss the value of certifications in the industry. While certifications are beneficial, Eva and Rowell stress that they are not the sole determinant of success; practical experience and a commitment to ongoing learning are just as important for employability and career growth.

As the conversation moves forward, Eva expresses her interest in signal processing and the electrical engineering side of Wi-Fi. She shares her struggles in finding structured learning resources in this area and contemplates pursuing further education in signal processing. Rowell highlights the value of understanding hardware, while François leans more towards the software side of networking. The discussion touches on the relevance of APIs in networking, with Eva sharing her experience working with APIs in the Meraki dashboard and how mastering APIs is a great starting point for those looking to expand their technical skillset.

Eva goes on to share her experience with automating network tasks using Python scripts, detailing how she was able to save time by automating repetitive tasks such as renaming access points and mapping their locations. Rowell agrees that Python automation can significantly reduce the workload for large-scale projects. Eva also talks about her personal transition to a remote role at Cisco Meraki, a move prompted by her father’s illness. She emphasizes how her Wi-Fi expertise helped her secure a flexible position that allowed her to balance her career and family needs.

Meter is going one step beyond AI chat bots with their product Command. It’s a generative UI that goes beyond command line interface and adds visuals to create custom dashboards using a natural language interaction.

A network operator can make queries for their network, configure SSIDs, new networks, and other network changes by using plain English.

Meter Command allows a network operator to be highly efficient and productive. A simple English query can yield results of the network. Or if you need to build a custom dashboard for a CTO, you can ask Meter Command to build that for you. No extra coding experience required.

Another great aspect of Meter Command is it is built to be collaborative with other team members. Troubleshooting can be kept in a single canvas and updated dynamically. Dashboards can be created and modified on the fly by collaborating with other team members.

Wi-Fi 7 is just around the corner. It offers new features and complexities to help increase throughput and maintain low latency. In this episode, we’re joined by Arista Networks who gives us a run down on the different versions of MLO.

With their testing, they’ve seen a few versions of MLO being used. As well as seeing when MLO gets triggered and how much throughput you can acquire when connecting to the same AP on different bands.

For stability, Arista Networks displays how preamble puncturing works when interference is detected in a wide channel. The specific channel seeing the interference is removed from the channel width without affecting the other channels.

Check out the video to see it in action.
