wireless bridging with A and B/G?

    does anyone know of a device that can handle bridging a wireless A in to a wireless B/G out?

    It will also need to have DHCP client support for the A side and DHCP server support for the B/G side.

    anyone have any ideas where to start looking?

    802.1a is 5.8GHz, 802.1b/g is at 2.4GHz

    Methinks the easiest way to bridge 802.1a with 802.1b/g is to get a router/switch/access-point of each type and interconnect the the two using a LAN jumper or through a switch.

    As 802.1a operates at 5.8GHz and 802.1b/g operates at 2.4GHz two separate PHY (physical layer) radios are needed. Off hand I'd say it's a pretty rare device (PCMCIA NICs notwithstanding) that would be so equiped. Plus, with the low volume would be a pretty high price.

    However, just because I've never seen one doesn't mean that it doesn't exist. I would, however, be surprised if these actually were common.

    you are absolutely correct in what the easiest approach is... unfortuately the solution I have to come up with cant involve the easy way out..... :grin:

    ultimately I am looking for a device that is going to function as a CPE to a customer so the price is going to come into play on what options I can go with.

    the PCMCIA route is doable if you go with Cisco products, but it is cost prohibitive so that route is out... but hey.. if anyone knows of a decient low cost router with pcmcia on it... im all ears... I sure havnt been able to find one as of yet...

    thanks for the input!
    keep em coming folks!

    Well done! That takes care of the Access Point part, any thoughts on how to handle the DHCP server requirement? Also, as I recall, genuine Cisco product tends to be quite pricey.

    Hang on, I just did a quick Google search and found out that there's a Linksys WRT55AG that should fit the bill and will come at Cisco-lite prices. See http://www.pcmag.com/article2/0,1759,1244111,00.asp

    Thanks to cgondo for putting the thought in my head. Good hunting.
