I recently installed CentOS 5 on my older Dell Insipron 8100. For wireless, I use a RangeLAN DS card (in Linux, this card uses the orinoco_cs driver and usually shows up as eth1). In previous versions of CentOS I had to manually identify the card by editing the wifi config files and possibly some other magic. CentOS 5 identifies this card just fine but does not function without a little bit of system tweaking. It seems that another kernel module named hostap_cs conflicts with the orinoco_cs module. I noticed that the status light on the PCMCIA card would continue to flash, instead of coming on solid when the card found the AP.

The fix is to blacklist the conflicting hostap_cs module so the system does not try to load it.

Edit this file:

/etc/modprobe.d/blacklist-compat

Add these lines and reboot:

# hostap_cs conflicts with orinoco_cs driver.
blacklist hostap_cs


Labeling on the Proxim card itself:

F/W Rev. : 0.7.6

The wifi card ident info:

I purchased for $15 from Geeks.com a few years ago (I'm fond of geeks.com for slightly older and cheaper computing gear).

Sometime last year, I removed Microsoft Windows from my home computer and installed Ubuntu Linux. It was a tough decision, because I knew I would not be able to play 3D games like Counter Strike Source. I finally found a free multi-player 1st person shooter that is similar to CSS, fun to play, and performs just fine on my not-so-new computer (Athlon XP 2800+ with GeForce 4 Ti 4200). The game is named Urban Terror and is based on the Quake3 engine. Downloads are available for Linux, Mac, and Windows. Did I mention that it is free?

We are making progress again with the help of our contractor. We will be adding around 600 square feet of new air-conditioned living space plus a small covered porch. The new rooms include a Family Room, a Studio / Guest Bedroom, and a Bathroom. A bonus feature is additional closet space in the Master Bedroom which shares a wall with the addition.

We will be replacing all of the windows in our house as part of this project and also blowing additional insulation into the attic and underneath in the crawl space. The new plans have a much more reasonable amount of glass than what the architect designed. These energy efficiency improvements will allow us to use the existing A/C unit instead of having to operate a second system.


The new spaces are colored in green:
