Switching guide: Lightweight vs Autonomous firmware for Cisco APs

Following are the three type of IOS available & need to download the correct type before starting the conversion process.
k9w7 – Cisco autonomous IOS firmwarercvk9w8 – Cisco lightweight recovery image  firmware– this is factory installed on lightweight APs, unless a “mesh” image is specified; it lacks radio firmwarek9w8 – Cisco full lightweight IOS firmware (this is what is bundled in the WLC .aes image, and is factory installed on “mesh” APs) In our case we require k9w7 for Autonomous conversion. More specifically c1140-k9w7-tar.124-25d.JA.tar as my AP is 1142.

To convert Lightweight AP to Autonomous AP, need to have PC directly connected to AP’s ethernet port. If you are powering AP from the switch (i.e use PoE) then PC & AP needs to be in two switch ports in the same vlan. In my example PC is & AP is

Cisco Aironet 1600 Stand-Alone configuration

Model used:
Cisco AIR-SAP-1602I

This model has default settings to take the settings from a controller/server.
However, We can configure this model to work as a Stand- Alone wi- Fi router.

Here is the Working Configuration for me:

Display the Address on Incoming Emails with AddressView

Display the Address on Incoming Emails with AddressView

Many people have multiple email addresses, especially those who use email for both work and personal purposes. In the workplace, Microsoft Outlook remains the industry-leading email client, since it provides many more features than most Web-based clients do. However, if someone sends you an email, only the recipient's name is displayed on the incoming email instead of the address. This can make it tiresome for anyone using multiple email addresses, since there's no quick and easy way to find out which email address the sender used to write to you. A common problem in such a scenario is that you end up sending a reply from another address causing confusion for the original sender. However, with AddressView, you no longer need to worry about managing multiple email accounts with Microsoft Outlook.

A Cheap and Simple Solution

AddressView has a simple purpose, and although it's a very lightweight tool that comes in the f…
