At the beginning of 2014 the 802.11ac specification had just been ratified and home routers supporting the draft version were already hitting the shelves in the local computer shops. It is interesting to see the difference between how fast 802.11n was adopted back when it was finally ratified in 2009 and how fast it looks like 802.11ac will be… Continue reading The impact of 802.11ac vs 802.11n in high density environments
These little gotchas are coming in thick and fast, this time CDP is disabled by default after the APs join the WLC or they don’t show up after a power outage. What does it affect? Seems to be affecting 3502 / 1142 APs so far What happens? The APs don’t show up in cdp neighbours… Continue reading CDP Disabled Cisco 1142 / 3502 Lightweight APs
What does it affect? Seems to be affecting random batches of 3502 / 1142 APs. What happens? The APs boot up with their LED happily flashing away but this merriment is short lived as once they join the controller it will turn itself off. Bit weird. Cue delirious panic from clients who think their APs… Continue reading Cisco Lightweight APs LED turning off

In creating these maps I’ve always been frustrated when it came to searching for a Controller or AP out of hundreds or even thousands of database entries.

I also realised that considering there are only 2 posts here one should attempt to populate my own blog with a bit of text. Have a read of George’s post and my response… Continue reading APs in monitoring mode
Cisco autonomous access points default to any clear channel including the “non-standard” 2,3,4,5,7,8,9,10,12. I believe I heard Aruba’s do too which means you need to disable those channels unless you don’t mind a bit of adjacent channel interference :-). This little gem was mentioned by Blake Krone during his recent podcast: http://nostringsattachedshow.com/2012/09/10/e14-getting-certified/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+NSAShow+%28No+Strings+Attached+Show%29
So! Post uno. What to talk about. The two main areas I am going to be droning talking about for however long the blog goes on are my ‘journey’ to become a half decent Wireless engineer – which I’ve just made another page for with details of any reading material / links I come across – and my… Continue reading I guess you have to start somewhere..
