Encryption won't work-wrt54GL/dd-wrt/Mac

    hope this doesn't post twice...just tried and it failed

    Anyway...here goes again: I have installed V 24 on a new WRT54GL, and configured it as a repeater bridge. When I enable encryption it will not connect to the internet. All 3 of my Macs see it in the airport menu, and I can select it's network, but it will fail to connect to the internet.

    If I enable encryption on the physical repeater and disable on the virtual, it works fine, but that's not giving me any protection.

    I've had a skilled tech friend guiding me thru this, and he'll probably discover the answer, but I thought I'd see if anyone has experienced this and get an answer straight away.

    I've tried WEP 64x10 or 128x26..neither makes a difference.

    Actually, I can't even log on to the repeater. When I select it and put in the password, it comes back with, "there was an error joining the airport network..."

    I've gone over all the settings and can't seem to figure this out. Why won't is work with security enabled? mmmmmm

    http://www.dd-wrt.com/wiki/index.php/Wlan_Repeater - is this the page you've been referencing?

    they have a number of "gotchas" - like the SPI firewall must be disabled, the Block WAN requests items must be unchecked, it must be in a separate subnet from the original AP, etc.

    try reading through the edits on that page to see how others have gotten it to work

    figured that out...now another question...

    Found there was a setting on the Mac that specified the encryption mode as WEP 40/128 bin hex. I was only using the basic WEP setting.
    Anyway, I'm doing this to try and reach our house next door, which is 400 feet away. I can only see the roof line of the house from here, and so far, have not been able to get the signal all the way over there.
    I've got my main AP router (WRT54G) sitting right here, and I brought the wrt54"GL", configured as a repeater, over to the other place...but got nothing at the house. There is a pool/pump shed, with power, 75 feet closer and I was able to get a little signal from there, but not great.

    It's been suggested that I flash my router with dd-wrt, too. That's supposed to crank up the distance potential.

    Any other ideas, by anyone are appreciated.

    400 ft is a stretch, you can adjust the transmit power in dd-wrt under "Wireless > Advanced Settings > TX Power", however, the better answer (and probably necessary) will be to buy a 3rd-party antenna to make that jump.

    Yeah...I cranked the power on both router and repeater, but I could only get 300 ft. with LOS placement. And that means I'll have to get a couple of those AC/ethernet transmitter thingies to get my modem signal to the router, since it's in an outbuilding. And, another one for the house next door, since the repeater has to sit at the pool pump house where there is power.

    Is there an antenna you recommend?

    thanks

    I haven't had a reason to buy an antenna yet, but basically there's two ways to do it.
    1) create a point-to-point connection with your routers acting as wireless bridges with the idea that the wireless signal will be used for only that link, using a parablic grid or yagi antenna, can get more distance this way
    2) use omni antennas and set up WDS with the idea that your routers function as access points for other devices as well as mainting the link between themselves
    side note: I've also seen an omni at one end and a parabolic grid on the other end, sort of a mashup of the two

    Unfortunately, though, I dont have a specific recommendation as far as brands, etc. Maybe someone else here does.
