Frozen Fi – The Big TX Freeze

We all find bugs in software from time to time and most of the time they are fixed in relatively short order.....maybe.... It is always an unsettling feeling when those bugs resurface in later versions of code after being "fixed."

Single Channel Architecture and Virtual Cell and its Effect on Co-Channel Contention

Leaving on a Jet Plane…East Bound and Down (to Virginia) from @CiscoLive

Ok...I know I promised blog posts every night. That was a first time attendee mistake.  Live and learn. This will be the precursor to a longer more detailed blog post about an amazing week at Cisco Live. No blog post will ever do justice to the incredible time that I had.

*UPDATE* Mis-Information Fixe(802.11)r

It has been brought to my attention that I may have posted some incorrect information. Thanks to both Andrew von Nagy and Jason Hintersteiner for raising the question of whether or not .11r is enabled by default. After thinking more about this, I realized that this would in fact be a weird default setting. After … Continue reading *UPDATE* Mis-Information Fixe(802.11)r

Husband, Father, Wifi Fixe(802.11)r

****UPDATE**** Thanks to Andrew von Nagy and Jason Hintersteiner for bringing this to my attention.  The 802.11r (FT) default setting in both the Meraki dashboard and Cisco WLC is in fact set to DISABLED.  I don't recall changing this setting, but I must have.  My apologies. ***************   At my house I have many duties.  … Continue reading Husband, Father, Wifi Fixe(802.11)r
