It starting to get a bit warm here, so I'm thinking that I'd like to move my Slack tower server into the garage where it'll be cool during the summer. My router is wireless, so I'm thinking that I'll take out the Netgear FA311 nic that's in there and get a nice wireless pci card. My laptop has an Orinoco which has a real good range and I see they also make pci cards. What other wireless pci cards are Slack friendly?

The Ralink cards are supported very well on Linux. LinuxEmporium sells cards that are tested to work on Linux: http://www.linuxemporium.co.uk/products/wireless/ , more information about the Ralink cards and Linux drivers can be found at: http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page

I'd like to buy a card that has modules built into the 2.4.29 kernel. I put one in my friends' pc that used a ndiswrapper module that I had to compile for each kernel. For my old pc, compilation would take days. Do the Ralink cards work out of the box with Slack 10.1?

Ah, 2.4.29 does not have many modern wireless card drivers. You may be able to compile the Ralink drivers on 2.4.29, but I am not sure about that. I am fortunate enough to have some (Orinoco) Prism 2.x cards. These WLAN chips have worked (except the USB version) out of the box on Linux for a long time. I am not sure if you can still get Prism 2.x based cards. Of course, maybe you can get one through EBay at a low price.

Yeah, if you really want something that is included in 2.4.x, I think Prism is going to be your only shot.

If compiling is the issue (because of a slow machine) you could try using the 2.6 kernel from the /testing directory. It could only have better support for WiFi than 2.4.

Why don't you just go to the Slackware Package Manager and install a more recent kernel?

looks like I'll have to update my kernel to a 2.6.x kernel. Are pci Orinoco cards good? I know they're expensive. I got a cheap Orinoco Classic Gold pcmcia card for my laptop that works great in Slack with kernel 2.4.31.

What pci wifi cards have modules built into the 2.6.x kernels?

Actually, for a 54g card, the atheros-based chipsets work pretty well too.

You can build the latest snapshots yourself -- or, if you're using pat's kernels from 10.2 or current, you can use alien's modules. Google for "alien slackware madwifi" and you'll find it.

There are more drivers in 2.6, but you don't need it (madwifi drivers aren't included yet, the 54g drivers that are built in are for hard-to-find cards like hardMAC prismGTs, etc). My experience has been that madwifi drivers work as well in 2.4 as 2.6. Don't upgrade your kernel just for this....
