    You'll need a bridge - something the Linksys WGA600N or WET600N programmed to your N SSID / security key to connect to the device. Or connect it to a small switch and put multiple devices on it.

    It will also speed up your G if you set the 2.4 band to G only.

    Ok, I thought I had said enough to show I'm not dumb, but I guess not ;) I know what DC is, my point is, if you are saying the receivers OR the power inserter are putting out DC over coax, either way it doesn't really make sense. If it's coming from the SWM splitter outside, then without a DECA box, what is happening to that DC power when it hits your receivers? If it's coming from the receivers, is the SWM splitter blocking it? If it's just passing through everything except DECA boxes, then do the receivers have some sort of a block on them and that is why older units require a BSF? I'm guessing the last one is the correct answer. Otherwise, it doesn't make sense that the DECA boxes would not be passing that DC through, and still have enough to power another DECA.

    It doesn't matter though, I have it all hooked up and it's working fine minus the broadband link. I went to use a switch, as someone suggested, but I worried about the fact that that switch was on a wireless link, and I was worried about routing issues. I don't really know if my setup is going to work properly with the broadband, because I have no way to put the DECA box by my router, as it's in a room with coax wired for my cable modem. If it's the gateway, traffic is going to try to go back to it for routing and then attempt to traverse the wireless link to my office. I ordered a two way green label splitter, but at this point, not sure how/if it's going to work.

    There are a few places DC is coming from:

    1. The SWiM PI
    2. Each receiver
    Each have a designed/planned destination. The splitter has only one power passing port, for the SWiM PI to power the SWiM. The SWiM PI voltage is higher than what comes out of the receivers.
    The receiver voltage either goes "nowhere" [blocked at the splitter] or to power a DECA.
    The DECA can only be powered from the receiver connection end, so you can't power anything else upstream of this as the DECA blocks the DC out the SWiM end.
    The BSF has nothing to do with DC and everything to do with blocking the DECA RF signal, which if the receiver or SWiM isn't blocked may cause distortion to the SAT signal.
