    Hi. Is there a new Section for Wish list for the tomato 1.22 ?

    it would be nice to have a turn off one antenna like the dd-wrt especially for linksys wrt54x series with 2 antennas that need to plug only one high gain antenna to the router

    by the way I have the GL version. I saw the version G have easy unplug for antennas but the GL version is not easy. anyone knows if GL allow to set a external antenna ?

    In Advanced->Wireless, you can assign Receive and Transmit to the same antenna. I would assume that would disable the other antenna, but I'm not sure about that. You may look into that if you are wanting that capability.

    I also have a WRT54GL, but I'm pretty sure I've disconnected the antennas just like my WRT54G. Do yours not detach?

    In the GUI, go to the page Advanced/Wireless.
    Change both "Receive Antenna" and "Transmit Antenna" to "Right" (or left;
    just make sure to use the same antenna.)

    Antennas are detachable on the GL, too. Definitely.

    thanks for the info that it could use only one antenna this is very nice. since I would like to add a high gain antenna. by the way linksys wrt54gl doesnt allow PoE doest it ?

    and yes sorry the antenna is detached yes you both are right thanks so much
    by the way anyone here have use the only one antenna to add a high gain antenna ? what was or are the experience with it ?

    thanks again

    Similar Question

    I have a similar question. I just bought a Hawking 14dBi Outdoor Directional Antenna(HAO14SDP) and was wondering if I should turn off the other antenna or if I needed to because I could damage the unit?
    I'm running DDwrt and using my wrt54g as a client or repeater. In client mode I have no issues, I point the panel antenna at the main access point and all my wired connections can connect fine.
    I was using repeater mode before(wrt54g picks up signal and I setup a virtual access point SSID and re-broadcast that signal) but was getting drops form the main access point sometimes so i decided to try a better antenna. once I got this Panel and i turn off the unused antenna I have issues connecting to my WRT54g if I'm behind the antenna(since the antenna has to be pointed at the main access point not around the shop).

    I'm sure someone has setup WDS and come across this issue when using a panel antenna to connect to another point, what do you do too keep get the signal strong on the backside of the antenna? do you leave the second antenna active? if so how do you set each antenna, both still to auto?

    If you leave the stub antenna in place, you must also leave the settings
    at "automatic" for both antennas. Please, report whether that works for
    you! (If it doesn't, the only alternative is to use two physically different
    transceivers with independent antennas.)

    If, however, you remove one antenna, you should change the settings
    accordingly, even though the TX power reflected from an open connector
    is IMHO not strong enough to cause any damage to the unit.

    No, and I'm not aware of any consumer-grade routers that do.

    With regards to PoE you can get a Linksys PoE extractor though and using it supply your router with power (also works for the SPA VoIP product line).. I even had it working with a first gen WRT54G which uses another voltage than the more recent models. Granted it's a second piece of hardware that can break independently of the router, but my routing and wlan closet has no power source and those splitters have enabled me to operate all devices that need to be there without the need for a power plug.

    Hello, don't know how dd-wrt will turn off wlan. With tomato you can do a custom script under Administration/Scheduler/Custom 1 (Enabled, Time 23:00, Everyday)
    /sbin/radio off
