Always Check The VLAN – Troubleshooting Wi-Fi In the wired networking world, we have an adage, “Always check the physical” – meaning the PHY layer or specifically the cables, connectors, and that you have a link light. So many times problems happen at the bottom of the OSI stack. I’ve found many times in the […]
After much discussion with K-12 customers, WLAN vendors, and other Wireless LAN Professionals, I thought it good to get all this out on the table in a single blog post. I started writing a post to explain my position on the approach some vendors and integrators use when selling Wi-Fi solutions to K-12 customers. The […]
The folks that brought us the specifications we have grown to know and love concerning different types of cabling – you know the Cat5e and Cat6 types of twisted pair cabling. Those folks have now stepped up and entered the fray of Wireless LAN Design.
Some of what they are suggesting is fine. Things like ensuring Gigabit Ethernet is available to all access points. But some of the other ‘wacky’ bits of the spec leave a lot to be desired. In fact, they are so far out there, you could consider them to be humorous.
This is the fourth and last in a series of blog posts about Public Wi-Fi opportunities. Of course, these are just the opinions of this author. Lack of Security Here is the biggest bugaboo concerning Fast, Free and Easy Public Wi-Fi. By definition, this is an open and unsecured network. Sure, we can put on […]
Right-Click Here To Download This Episode In this week’s episode, our main topic is an interview I had with Kelly Griffin while at the Airheads conference. We’ll discuss Frame Type Ratios in our tutorial, and we’ll find out just WhoIs Keith Parsons. We’ll also lookup the term “Intrusion Detection” in our Geek Glossary.
This final description of good public Wi-Fi is another one with lots of controversy. First a caveat, if you live in a country which has some crazy law which forces a solution other than this easy one – obviously you’ll need to follow the laws of your country. Or better yet, lobby to remove such crazy restrictions!
This is the second in a series of blog posts about Public Wi-Fi opportunities. Of course, these are just the opinions of this author.
I know this one is going to cause some consternation with folks who like the seemingly easy sale of pushing Wi-Fi that “pays for itself”. But I again plead for you to think of how you personally like to access the Internet. I doubt any of you reading this enjoy paying for something that is normally free in other locations.
The simple truth is Wireless LANs cost money. They cost money to design, install, and maintain. There is also the on-going cost of providing the Internet backhaul. Yes there are some substantial costs involved. But no more so than other free public services businesses provide their customers all the time.
A couple of examples of other services the have both up-front, and on-going costs that businesses gladly pay in order to support customer expectations:
• Public Restrooms
• Public Lobbies
• Security Cameras
• Security Services
• Custodial Services
• Snow Removal
• Garbage Services
• Free Breakfast in Hospitality
This is the first segment of a series of blog posts about Public Wi-Fi opportunities. Of course, these are just the opinions of this author. But it comes from interviews with hundreds of customers.
Many in the WLAN industry who like to sell solutions to their customers might find the attitudes reflected in these posts as counter to them making more money. But the reasons for this series is to make folks think. Think about how you PERSONALLY would like to access Wi-Fi.
So please read and think about how you, your friends, your family, and others you know would LIKE to have access to Public Wi-Fi.
This tiny AA battery-operated device is fantastic for helping WLAN installation teams to test the wired side of the network prior to installing any access point.
I’ve been training installers to ALWAYS test the wired side before every installing and access point. If there is a problem with the VLAN assignment, or DHCP pools or any of a number of possible wired network issues – it is so much easier to fix them BEFORE installing the AP. Because after the AP is up and running, any issue becomes a wireless issue. Even when it’s not.
Enter Linksprinter. It is like a baby version of the LinkRunner AT. It can do many of the same function, albeit in a simpler way and with only the small lighted icons to tell you status.
