    In my home network I have two computers connected to my router by wire (I need the faster connection for these), and three PCs wirelessly. For the wireless range to be adequate, the router needs to be on the middle floor (of three). But this would require two 15m RJ45 cables for my wired PCs and another similarly lengthed RJ11 from the microfilter (all of which are downstairs). Now, I guess a more suitable option would be to keep the router downstairs and sort of extend its antenna cable to reach upstairs.

    My question is, can an antenna cable be extended, and how far can it be extended before it begins to lose effectiveness of signal? And how about those new Wireless-N ones with three antennae? Can these be extended?

    I know I could buy a repeater but I want to see if itÂ’s possible without much buying any other devices for my network.

    Thanks

    I'd forget about long wires on the antennas. The losses in a long antenna wire will eat up any advantage of moving the antenna to a more optimal location.

    Of course, you really only need one CAT5 cable to downstairs, a cheap Ethernet switch will split out the wired connection to multiple computers.

    Perhaps you should consider just increasing the range of the wireless router where it's located now.

    Hawking Tech has a number of products that will help you increase your wireless range. The root page is Hawking Hi-Gain™ WiFi Range Extending Products.

    Some of the more interesting products are this Hawking [HSB2] Hi-Gain WiFi Signal Booster, which can be used on either end of a wireless connection to boost the signal power.

    Another way to increase your signal strength is by the use of hi-gain antennas. You can choose from omni-directional or directional models, here are a some examples.

    Hawking [HAI7SIP] Hi-Gain 7dBi Omni-Directional Antenna

    Hawking [HAI15SC] Hi-Gain 15dBi Corner Antenna

    [HAO14SD] Outdoor Hi-Gain 14dBi Directional Antenna Kit


    This is just a sample of available products, many people have hi-gain antennas with similar specifications, but I haven't seen any other suppliers of signal boosters.
