Fixing Cisco Wireless Client Association Failure ReasonCode: 102

Have you seen this error in your Cisco WLC logs?

Client Association Failure: MACAddress:xx:xx:xx:xx:xx:xx Base Radio MAC:xx:xx:xx:xx:xx:xx Slot: 0 User Name:UNKNOWN IP Addr: unknown Reason:Unknown ReasonCode: 102

There is one link on the internet mentioning this error on the Cisco Support Forums, but I found it might have an alternative solution.

Reboot the AP with the Base Radio MAC that is triggering this error.

I highly doubt this is a silver bullet for this error, but when there’s little other documentation on this error online, I figure I’d share what my fix was.

Fix Surface RT Limited Wifi Connection

NOTE: Changing the BAND settings below will cause 5Ghz wifi to no  longer work on your Surface. You must keep BAND at 6 for 5Ghz wifi connectivity.

10/31/2016 UPDATE:

This setting is now found in the following location:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e972-e325-11ce-bfc1-08002be10318}\0000]
 "Band"=dword:00000004
 "[2.4Ghz or 5Ghz]AutoUse40MHz"=dword:00000000

Tip came from: https://kb.iu.edu/d/bdms and modified slightly by me.

This helpful tip came from a long Microsoft community thread. Until Microsoft gets a fix for this, the best result is to disable Wireless N mode on the Surface, which is the cause of the connection problems.

1) Open regedit.
2) Go to the following tree location:
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\”
3) Find “AutoUse40Mhz” and set it to “0” (“1” is default)
4) Change the entry below this named “Band” to “4” (“6” is default)

Reboot and Surface will connect using only the 802.11 b/g band, instead of the N band.

This has been working well on my Surface RT so far. Hopefully Microsoft gets a permanent fix for this. :\

Google’s “Wifi Location Opt-Out” policy is horrible and flawed.

In one of my previous posts, I wrote how Google and other companies are tracking our locations via Wifi routers. In order to do that, these company must have a database that stores all of the wifi routers it can find, and their locations.

Google FINALLY just introduced a way to remove your router from their system, however their method is ridiculous, and here’s why.

Reason #1: The “removal method” is so bothersome, most users won’t use it.
