Cisco 877W [Wireless Config]

Published April 17, 2009

Well i thought id post a Cisco877W wireless config, configured only as a access point. So..you can cut bits here and there and fit it into your existing 877 configuration. Bold indicates what you may need to change..

Cisco uses the Centre Frequency MHz to configure its wireless channel. So in our example below 2442 is used, which means that is actually Channel Identifier 7.

For more info on this you can see go here http://www.cisco.com/en/US/docs/routers/access/1800/wireless/configuration/guide/s37chan.html

Cisco IOS Feature Navigator

Published February 9, 2009

So you got your cisco device, but what if you want to quickly find the right IOS, and other software releases for features you want to run on your network. There are many different versions of the cisco IOS for each device. I came accross this handy cisco website which you can use to research software releases by searching by image name, platform, product code etc. Once you select what you want, it will give you more information about the particular IOS for your device, and what it can run.

So checkout:

http://tools.cisco.com/ITDIT/CFN/jsp/index.jsp

I believe it will come in quite handy!
