Connecting to my college across the street using my router?

    Hey folks,

    Just curious but I would like to connect to my University which my
    wife works at across the street from me.
    I am using the following router...
    As it is now I have wireless with my ISP to my modem in which I have
    a cable to my wireless router.
    From the router I have a direct link to my PC and use my laptop
    wirelessly to the router.

    I would like to disconnect from my ISP and hook up to the University
    across the street.
    I will use an external antenna but where on the router will it
    connect? The antenna has an "N"
    female connector on it.

    I would think I would have to go to the "WAN" port on the router...
    is this correct?
    Just not sure how to go about this connection. The antenna would go
    up on my roof with a dish
    and is probably 150' run.

    Thanks guys

    Unless the stock antenna can be removed there really isn't any place
    externally to hook it up to.
    You would NOT use the WAN port. You would use the router as an access
    point, if it's capable of this.
    You then become a client on the college network.

    Oh ok cool. Kind of checking this out for a friend, I'll let him
    What if he had a WRT54G with two antennas, both removable though?
    How would you go about doing it then but still be able to use your
    inside your house?

    Thanks buddy'

    Note: With such a long coax run, you would need super-low-loss coax, LMR400, which will run $1/ft
    terminated with connectors on both ends.

    The other option is to mount the AP in a weatherproof NEMA enclosure as close to the antenna
    location as possible and use less expensive coax on a MUCH shorter run.

    Have you ever run 150' of coax ? Not fun.

    With that cost, and the cost of an antenna, and the general PITA the whole deal is, you'd be better off
    to just buy something like this......

    An outdoor, fully integrated (includes antenna) unit that uses POE. It's a *LOT* easier, and in the long
    run, less expensive to run 150' of CAT5 cable (@ $65/1000 ft.) than coax. You would mount the device
    where you plan to put the antenna, and then just run CAT5 to where it will end.

    You had mentioned connecting to the WAN port. IMO, with a 'regular' rtr this IS what you would want to
    do. That way, the U. would only issue 1 IP address thru DHCP, and the rtr would NAT your local inside
    LAN to the U., just as it currently NAT's to your now ISP. AND, you would be isolated from all the other
    U. WLAN traffic, which, again IMO, is the best way to go. There's absolutely no reason for the U.'s
    other WLAN traffic to get inside your LAN. You don't want that. That's almost as bad as being
    connected directly to the internet.

    Now, if you were to use something like the device I linked above, you would set it to ClientMode w/NAT.
    What that means is that the device would become a client on the U. WLAN, AND provide NAT for the
    internal LAN. That device would then just uplink to the existing AP and you could also use the wireless
    at the off-campus location, NAT'd.

    I don't know the policies of connecting to the U. WLAN though, so I can't help you there.

    Hmm all sounds very interesting. That piece of hardware above is
    I told this dude that I'll be posting this here for him, I just hope
    he's taking it all in.

    Ok cool, thanks guys!!
