Two Wireless Routers?

    Here's how I would like to set up my laptop and my desktop with respect to a
    wirless connection to my cable modem:

    The laptop is old - P2-266Mhz with Windows 98 (now that's old!). I have an
    older Trendnet wireless PC card (TEW-226PC) installed in one of the PCMCIA
    slots and a matching Trendnet 802.11b wireless router (TEW-231BRP). These
    only support WEP security.

    My desktop is new and I am utilizing a D-Link DWL-G122 USB network adapter
    and a Hawking HWR54G 802.11g wireless router, which supports WPA-PSK security.

    All the 802.11g wireless network adapters require prerequisites which exceed
    my laptop's specifications, so I can't connect it to the Hawking router if I
    want to continue using WPA-PSK security on that router. Therefore, I would
    like to operate two wireless routers - one for the desktop and one for the
    laptop (which I plan to use for basic surfing i.e. no need for WPA-PSK

    Is this feasible? If so, what's the best approach - get a "splitter" so I
    can attach two RJ-45 cables from the cable modem (one to each router) OR
    connect the 802.11b router to the cable modem and then the 802.11g router to
    the 802.11b router OR some other configuration? Do I have to worry about
    interference between the two wireless routers or can that be solved by
    setting each to use a different channel? I would really like to be able to
    keep using the laptop, so any help would be greatly appreciated. Thanks.

    Basically, as long as you have yoru connection secured, that is the main
    thing. WPA is allegedly better than WEP, but both wil stop all but the most
    determinedatatcak, so long as they're setup NOT to advertise the
    encryption-key or SSID.

    The two wireless adaptors need to be on different channels. If so they
    shouldn't interfere, with the possible exception of 105MHz wireless, which
    uses more than one channel.

    There are two ways you can retain the old router;

    You can set it up as a simple LAN-to-Wireless passthrough link, by
    connecting one of its LAN ports to the new router (which provides the cable
    link) In this case turn off its Cable/DSL, DHCP and NAT functions. The old
    laptop will probably be able to get an IP from the new router's DHCP by
    straight passthrough -or since it's the only host of its kind, just give it a
    static one.

    Or, you can connect the WAN port of one router to a LAN port of the other.
    This is known as a 'double NAT' setup, and provides further isolation between
    the two groups of wireless users. In this arrangement, the the two routers
    will use a different IP network-numbering scheme, say 192.168.1.x on one, and
    192.168.2.x on the other. The machines on both routers will be able to browse
    the net, but those on the 'downstream' router will effectively be isolated
    from those on the 'upstream' router.

    There is No reason that the old laptop with Win98 and the 802.11b would not
    be able to connect to the Hawking.

    802.11g is downward compatible with 802.11b.

    You cannot connect two Routers to one Broadband connection.

    You can connect the 802.11b Router as an Access Point with a Switch to the
    first Router; this is the way to do it.

    Beware that some of the 802.11g Wireless might under perform in at presence
    of 802.11b Wireless Router.
