How To Enable Roaming Support for a PCMCIA WaveLan With RedHat 5.1

NOTE: With these patches, roaming is on by default. To disable roaming, or to be able to turn it on/off as needed, one must first perform the following steps.

1. With the kernel source installed, cd /usr/src/linux
2. make menuconfig
3. Select the "Network device support" option.
4. Enable Radio network inferfaces.
5. Disable all of the radio network interfaces listed below that option unless you specifically need them. You also SHOULD disable the WaveLAN/RoamAbout support there unless you need to use the ISA version.
6. Exit, saving changes.
7. make dep ; make clean ; make zImage ; make modules ; make modules_install
8. cp /usr/src/linux/arch/i386/boot/zImage /boot/vmlinuz (or wherever your kernl is installed)
9. lilo
10. reboot

You also should download the latest wireless_tools kit.

Below are the steps for installing the roaming patch

1. Download roaming.patch and place it in /usr/src/linux
2. Download pcmcia-cs-3.0.7.tar.gz and place it in /usr/src/linux
Note: This should work with pcmcia-cs-3.0.3 and higher.
3. cd /usr/src/linux
4. tar -xzvf pcmcia-cs-3.0.7.tar.gz
5. patch -p0 -i roaming.patch
6. cd pcmcia-cs-3.0.7
7. make config
8. make all
9. make install

(steps 10,11 for MIT Media Lab systems only)

10. Request a static wireless IP from NecSYS.
11. Modify /etc/pcmcia/network.opts to look like the following:

case "$ADDRESS" in
*,*,*,*)
    # Transceiver selection, for cards that need it -- see 'man ifport'
    IF_PORT=""
    # Use BOOTP [y/n]
    BOOTP="n"
    # IP address
    IPADDR="18.85.18.xyz"		### Static IP from NecSYS goes here
    # Netmask
    NETMASK="255.255.255.0"
    # Network address
    NETWORK="18.85.18.0"
    # Broadcast address
    BROADCAST="18.85.18.255"
    # Gateway address
    GATEWAY="18.85.18.1"
    # Domain name
    DOMAIN="media.mit.edu"
    # Nameserver #1
    DNS_1="18.85.16.200"
    # Nameserver #2
    DNS_2="18.85.2.171"
    # Nameserver #3
    DNS_3="18.85.2.138"
    # NFS mounts, should be listed in /etc/fstab
    MOUNTS=""
    # For IPX interfaces, the frame type (i.e., 802.2)
    IPX_FRAME=""
    # For IPX interfaces, the network number
    IPX_NETNUM=""
    # Extra stuff to do after setting up the interface
    start_fn () { return; }
    # Extra stuff to do before shutting down the interface
    stop_fn () { return; }
    ;;
esac

For the non-roamers at the Media Lab, here is a list of the NWID's that I am aware of:
