Apparently I dont have a clue when it comes to wireless. This was set up before I got involved with this organization. We have a Cisco 850 with a Wirless card, and an Aironet 1200. Each placed at each end of a building. Clients can intermittently connect to the 850 (with an antenna right above), but always try to connect to the 1200 on the other side of the building. It seems like the 1200 has a stronger more reliable signal than the 850 even though it is far away. I am just trying to configure simple roaming with the clients. Any thoughts? Please Assist.
My reasoning is that if a laptop near one radio is jumping to the other , then most likly the cell sizes are much to large.
Granted you may have a faulty radio or a loose antenna.. Or someone thought it would be nice to hang xmas lights off of it for the new years party. :)
Go onto your 1200's web interface. Click on 'Network Interfaces' it will be on the left hand side.
Now click on the radio in question., such as Radio0-802.11G. Now a new page will appear and there will be a series of tabs at the top of the page. Third from the left is 'Settings', hit that and scroll about halfway down the page and look for 'power'.. Likly its set to default.
Since your likly doing this during production hours don't touch anything yet. Once you have a maintance window you will be able to dial it down a bit if required. Use a laptop to ensure you dont turn it down to far.
You really should look at doing whats called a site survey. Take a look at this book, its available via safari or your preferd book supplier. Its by Cisco Press.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
