    make sure you have a WIFI router that can broadcast b/g.. in addtion, you need coverage, so get WAP (wireless access points) as applicable to your facility.

    inherent problems are security, range, and other WIFI networks.

    Should you decide on a particular brand then use components based on the manufacturer (no mix/matching)  This will ensure compatibility.  Such as

    Router -
    WAP -
    NIC - (use Rangemax series)

    Security....use 128bit encryption that is built-in to the router.

    I've personally used the RangeMax 240 in one of my client's 20,000sq ft. restaurant... no added WAP was needed.  Just stick it in the ceiling.

    I have something like this setup in my office. Here is what I have done:

    I have a DSL line what is outside out my firewall and network all together. I setup my guest network on this "what I call" dirty connection. The DSL line is there for backup and as the main point of connection for outside users to connect to my network. I did this because then if someone try's to connect to my network with an infected machine, it doesn't infect anything else. Works great for me, haven't had trouble with it yet.
