    ('binary' encoding is not supported, stored as-is) 1- Can a wireless router (installed in their home-office) be
    hacked into AND can this hacker take control of the wireless
    laptop. If so I would need some detail on how we can prevent
    that (besides WEP). Let's assume for the sake of discussion
    that there is no WEP encryption on the router.
    >> Yes, of course it can be hacked into, esp if security is not enabled. WPA-PSK + MAC address filtering + disabling SSID broadcasting would be a good start to defending the router/network.

    2- How easy is it to access the laptop once you're into the
    router? Is it child splay or do we need a specialist?
    >> Good security is layered. If someone is able to access the network, that does not automatically entitle that user to access a computer on the network. But of course, it makes it a step easier, since at least one security layer has been penetrated.

    3- If the laptop's wireless router is secured with WEP and
    connected to the office via VPN can it be EASILY hacked
    into? The VPN connection gives them little access to the
    network, barely what they need to work. Will the intruder
    have access to our network?
    >> Assuming the intruder gained access to the wireless router (and an IP address was issued to the intruder, etc), the intruder would then need to gain access to the VPN. I don't think that would be nearly as easy as it would be to crack WEP (in lieu of WEP, it is recommended that people use WPA-PSK if both your router and wirelss NIC cards support it).

    4- How secure is my sales rep. running around hotels with
    his laptop?
    >> Depends on the individual. I'd go over basic security guidelines (not opening susipicious email, not installing suspect software, etc).
