Linux Step By Steps

WIRELESS PCMCIA

Here are some tips I'd like to share about using Linux with the Linksys WAP11 wireless access point in conjunction with a Linksys WPC11 PCMCIA
wireless card and optional PCI adapter. This hardware provides the user with the ability to share networked resources such as printers, storage, and even use
their computers in the client/server mode.

I am running a mixed platform environment consisting of desktop systems running Caldera eDesk 2.4 (kernel 2.2.14) and Win98, and a laptop running Caldera eDesk 2.4/NT4.0. All of the computers reside in different rooms and connecting these computers using wired ethernet is not feasible. To network
these computers without wire, I installed the following:

* Desktops running Caldera eDesk 2.4: single ethernet card attached to hub and WAP11 access point
* Win98 desktops: WPC11 PCMCIA card with PCI adapter
* Caldera eDesk2.4/NT4.0 laptop: WPC11 PCMCIA card

On my Linux desktop which is being used as a gateway, I have enabled IP forwarding and IP masquerading (set up procedure described in other SxS notes).
This allows sharing of a single telephone modem or cable modem connnection with your other computers.

The software provided with the Linksys AP was installed on a Win98 desktop and used to remotely configure the AP (setup procedure for Win98 described
in Linksys AP documentation).

The PCMCIA software for the Linux laptop was configured using the procedure described in Marrianne Talyor's SxS. The only tweaking required is the insertion
of addresses specific to your network in /etc/pcmcia/network.opts.

Reboot the laptop and it'll be ready for use in the living room, outside on the patio, etc.

I've tested ftp file transfers at an AP-to-PCMCIA card distance of ~125 feet and achieved a transfer rate of ~550Kbytes/sec (Linux-to-Linux), which is comparable
to a wired 10-baseT connection. Linksys specs the maximum working distance at ~1500 feet (transfer rate drops with increasing distance due to reduced signal strength).

I know what an adventure it can be to set up new hardware with Linux (often not knowing whether the hardware is supported by existing drivers!). Hope this note helps other Linux users - can't let the Windoze guys monopolize the new gear.
