Andrew vonNagy and Marcus Burton Today I attended the first Wi-Fi Mobility Symposium. The event was a gathering of panelists from key Wi-Fi companies and it was moderated by Andrew vonNagy (Revolution Wi-Fi), Marcus Burton (CWNP) and Stephen Foskett (Pack Rat). During this event, the attendees, panelists and moderators discussed the current state of Mobile Devices & BYOD, Hotspot 2.0 and the

If you find yourself surveying with a very old version of this Terrawave battery pack and it is suddenly not charging, or only works when it is connected to the wall charger, the fuse in it may have gone bad. Remove the main unit cover, and you will see a plastic housing with a glass fuse in it.  The glass fuse was broken, so I replaced it with a fuse I purchased from RadioShack (4/$2.00).

Remember the death of analog TV? Those unused analog TV channels are now approved for use as wireless White Spaces. White spaces operate at lower frequencies, and are able to travel great distances just as analog TV signals did when they were in use. Supporters of white spaces say that use of these regions of  licensed spectrum offer the same benefits of WiFi spectrum with the added advantages

Recently I've come across a lot of great out of print or public domain Film Noir movies shared on YouTube. Being able to watch these films is great in itself, but I really love it when technology figures into a critical character development or plot twist in a new way than in any of the other films I've seen. The plot of 711 Ocean Drive (1950) had a considerable amount of technology featured in

I made this recording back in 2009 to show how you could use Adobe Acrobat Pro to scale a floor plan, and ultimately find the square footage of a given area. More often than not, I'm faced with figuring out the square footage of a building layout with no scale indicated on the drawing. Adobe Acrobat Pro has a measuring tool built into the application. You can take any image file, find the scale

I'm very excited to inform you (if you haven't already heard) of the second Wireless Field Day that'll be taking place in San Jose on January 25th - 27th 2012. Assuming that the Mayans are wrong, we will be gathering in San Jose to hear presentation from a great group of wireless companies. The majority of my career I've been focused on Cisco's wireless hardware line, so I'm looking forward to

There are a couple of great how-to guides for configuring Office Extend APs on the web. Once upon a time, documentation for the OfficeExtend feature was a rarity. Back then the only guidance was from this great post from Blake: Cisco OfficeExtend AP600.

I don't get the opportunity to speak in public very often, but when I do have an opportunity come my way, I try to embrace the natural fear of public speaking and make a video recording of my presentation. There have been a couple of times where I've presented and I was so nervous, I forgot to hit the record button! Making a video of the session allows me to see what I'm doing right or wrong,

I've been thinking about the fear that some enterprises have about the possibility of someone bringing an access point from home and connecting it into the LAN at work with no security enabled. Most wireless vendors have a way to determine if rogue access points are actually connected into the wired LAN. Cisco's WCS has the ability to track a rogue access point on the LAN via RLDP, but it has

I'd been waiting to see when the Sony NEX macro lens would be available, but I found a modular kit of tubes on eBay & ordered them to see what it was all about.

I was chatting with @the_wifi_guy the other day and he asked me if I had any videos on how to use the Cisco Spectrum Expert application. I found an ancient video I recorded back in 2008 when it was called AirMagnet Spectrum Analyzer. I edited out the customer specific information and posted it to YouTube.

The very first 802.11 wireless networking standard was ratified in 1997. These first wireless networks were very slow, and barely usable. Early 802.11 used FHSS modulation and could only achieve speeds of 1 and 2Mb. It wasn't until 1999 when 802.11b was ratified that wireless networking began to really catch on and speed up. Around the same time, 802.11a access points were available and could

I've had a Blackberry since the inception of the 950 Internet Edition. I made the switch to the iPhone 4 mostly because of the problems I've had with the BES server at my current job. Every 15 days or so, I'd stop receiving corporate email. The 'fix' was to delete & re-add my account to the BES server.

When a switch detects a new revision number that is different from the currently stored value, the switch sends a request message to the VTP server and

Problem - configure connections to not pass BPDUs without disabling STP on the port. There is a good conversation on how to reduce the STP CPU utilization due to a high number of VLANs configured on a given switch on Cisco's NetPro forum.  The following links are referenced in the post (including those links here just for good measure). http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/

I've been carrying my cables around in Ziploc® bags for far too long.  Now I am officially organiz-ized (at least when it comes to my cables). I found some great, heavy-duty fabric (Made in USA) and commissioned my favorite Etsy seamstress Zigzagstitches to whip up some zippered cases for all the stuff I carry in my backpack.  I thought I'd share pictures of her handiwork in case anyone else

Last week I was performing a passive site survey of a currently deployed WLAN in several large hospital facilities in south Texas.  During the course of a week and entering countless patient rooms I validated an opinion I'd had for some time. Out of the dozens of patient rooms I entered, at least 12 or so people understood what it was that I was doing and told me they were using the guest WLAN

So, you may or may not have heard that there is going to be a Wireless Field Day taking place in San Jose March 17-18th through a lot of hard work by the fine folks at Gestalt IT.  Stephen & Claire along with the help of the delegates are working to make the first Wireless Field Day simply stupendous.  There hasn't been anything like this put together before - and this is a first in many regards.

Taken from the H-REAP deployment guide: The CAPWAP, on which Cisco's Unified Wireless Network architecture is based, specifies two different primary modes of wireless access point operation: Split-MAC—In Split-MAC mode, the system shares key functions of the 802.11 specification between the access point and the controller. In such a configuration, the controller is not only responsible for

My pal @revolutionwifi (Andrew VonNagy) wrote up a great post about Cisco CleanAir and his real world experiences with it, so I thought I'd follow up with a couple of little videos of some demo gear I'd been working with for a couple of weeks. In the first video, I go through the configuration steps outlined in the Cisco CleanAir Deployment Guide.  At first I didn't realize that when I set the

The Impossible Project is a group of people dedicated to creating a new instant analog film product designed to be used in Polaroid cameras.  The first type of film they created is a black & white/sepia tone film called Silver Shade.  Just recently they've launched the first new color film for Polaroid cameras called Color Shade.

The question has been asked: Is there enough demand to support a Wireless Tech Field Day? I know I can count at least 15 ~ 19 wireless people on Twitter that might like to participate as  delegates, and at least 27 or so companies that could participate as event sponsors.. So, I'm throwing this survey out there to find out what companies you'd be interested in meeting with and to see how many

Last week I took part in a unique meeting of the minds - now I freely admit that I didn't get everything that was discussed, but neither did @plankers.  He was (and is) The Lone Sysadmin, and I was the only wireless person in attendance.  I did learn a lot, and took a lot of notes.  It seems to me that large companies have a hard time dialing back the sales pitch, or the back story of how they

Thanks to @the_wifi_guy for pointing out to me that there is an updated version (7/22/01) of the WLC Config Analyzer on Cisco's site. You'll need a CCO login to download it, and there's also a webex archive explaining how to use the config checker. If you've never used it before, I recommend downloading it and using it to parse through your current controller configs and see what parts of

I've never been invited to anything like this before, and I'll do my best to take it all in & put it into a useful format to share.  I'm not 100% sure what to expect, other than information overload for sure.

I had the pleasure of being a guest on Etherealmind's Packet Pushers Podcast this weekend.  It was a lot of fun to get together with @etherealmind @ecbanks and @rovingengineer and 'chin wag' about all things network related. I'm glad I was able to take part in such a great podcast - I love listening in & hearing what other network engineers around the globe are getting up to from week to week.

I know this topic was beat to death a few months ago when it actually launched, but I thought I'd take a moment or two and gather my notes on the technology - the pros/cons and hidden caveats. The 3500 AP cannot influence the 1250 or 1140 to change its channel, the 3500 can only influence other 3500s to react to the interference 'seen' by a 3500. APs must be within 150 feet of each other for

Mark Yensen from MetaGeek sent me a Wi-Spy dBx to do some beta testing of their Chanalyzer Pro application, so I thought I'd pit it against the application I use most often for spectrum analysis - Cisco Spectrum Expert. At first glance, the Chanalyzer application was very impressive, especially with the Wi-Spy dBx price point of $599.00.  I liked the device signatures collected in Chanalyzer

Cisco's "Wireless Quality-of-Service Deployment Guide" ©2003 [I've never seen this doc before!] I stumbled across this crazy old document from 2003 outlining using QoS on VxWorks APs! I don't think much has changed in the way of WLAN QoS - at least not the fundamentals.  I'm hoping this will help make the QoS grooves in my brain deeper and more permanent.

So after some digging, I think I might have this figured out. The AP config guide has a section on giving priority to Voice traffic, but it doesn't show the CLI alternative to the GUI configuration section in the guide: Cisco IOS Software Configuration Guide for Cisco Aironet Access Points, 12.2(13)JA Giving Priority to Voice Traffic The 7921 Deployment guide only gives you the CLI commands "

QoS Example LAN Switch ConfigurationAP Switch Configuration The QoS configuration of the AP switch is relatively trivial because the switch must trust the DSCP of the LWAPP packets that are passed to it from the AP. There is no CoS marking on the LWAPP frames coming from the AP. The following is an example of this configuration. Note that this configuration addresses only the

So it has been a while since I setup a WiSM from scratch.  I was trying to do it strictly from memory.. and I totally forgot that each of the WLCs on the WiSM need to be put into their own port channel. If you put all the giX/X interfaces into one great big port channel, neither management interface will be "pingable" by the 6500 that the WiSMs are in, but that vlan interface will be up/up and

Taken from the Deployment Guide for Cisco Guest Access Using the Cisco Wireless LAN Controller, Release 4.1 Layer 2 Roam:A Layer 2 roam occurs when a client leaves one AP and re-associates with a new AP, in the same client subnet. In most cases, the 'roamed to' AP is connected to the same WLC as the original AP.  The description above represents the simplest roaming scenario because a single

Recently there has been some debate between two wireless vendors regarding which type of antenna is better than another.  Words were exchanged, and the one side made the statement that omnidirectional antennas suck. I started to think on this a little more and tried to see where they were going with this train of thought.  There are instances where you need a patch, yagi or otherwise sectorized

Things have changed a lot since 4.2, but for the lab - time is standing still with the 4.2 code.  Don't forget that you'll be expected to do things as the used to be done, not as they are now in 6.0 code..

I like the QoS  charts that are in this chapter of the design guide, but the chart runs of the page and isn't color coded like the nice QoS charts from Cisco Live BRKRST-2500 Campus QoS Design. The LWAPP AP and WLC perform QoS baseline conversion, so that WMM values as shown below are mapped to the appropriate QoS baseline DSCP values, rather than the IEEE values. From ccie(w) In cases

The "Lost Heartbeat with supervisor" error message is received on the WiSM controller at regular intervals. Why is this error message received? How do I get rid of this message?

In addition to the HELLO message, the controller colleges neighbor messages from its APs.  These collected neighbor messages
