hbest option to improve my network signal

    I installed my WRT54GSV4 (flashed with HyperWRT Thibor15c) centrally in the house but i am now slightly disappointed about the signal i get on my Tower PC carrying a WMP54GS card which is about 12 meters away from the router (with 3 walls in between). I only get a "low" signal (2 bars) and speed fluctuates between 11mbps and 54mpbs. What is my best move to get a better signal?

    - Place a better external antenna on the router on the outside wall of the room it is placed in (if so, what brand, type?)
    - Put better antennas on the router itself (something like the HGA7T)
    - exchange the antenna on the PCI card from the tower (which is standing under my desk) to a model on a deskstand (if so which brand/type recommended).

    p.s. moving the PC is currently not an option

    This is going to open a big can of worms simply because not all homes are created equal as well as not all walls are created equal. We have folks connect 1.5 miles across a field on one end and then we have folks like yourself that have a hard time connecting with just 3 short distance wallls. The biggest issue with walls is where does the electrical wiring run. In your case i would venture to guess at least one of the walls has one of the houses major circuits and thats causing most if not all of your interference. Sometimes just repositioning the router within the same room will help. However all the things you have mentioned will work too, which will work the best? Only experimentation will tell you that. I have had instances myself with goofy router placement where it was becoming so much of a hassle that i just ran a long cable run and put the router in the same room and all my problems vanished. The funny thing for me was i can now move around the house and even back to where the router originally was and still maintain adequate connectivity, go figure.

    the thing is that moving the router is the only option i cannot do. I have fixed it in the basement staircase and along with that routed all the cables to that spot. Furthermore i have also installed my VOIP phonebase on the same spot. Fact is that i also have a Nokia E61 that has wlan which gives me a better signal sitting at my desk where the tower is located. I guess all in all removing the antenne from behind the tower to a desktop stand wil already do something good for me. I only wanted to know what gives the highest chances on improvement since in any case i need to spend money and i want to spend it on the right solution.

    The depending on if you plan on moving around the house or just using the wireless for that one desktop, you can go with a directional antenna on both sides for best improvement. Or just one side for better improvement. I see them onsale all the time or if you are so inclined, you can make them for less then they cost to buy, just takes alittle time. But as you have notice just by slightly moving the desktop antenna that you can massage the signal a little, obviously there is some major interference in your place finding out how to get around it can be a different story. Sometimes something as simple as moving the position of the antennas can change your signal for the better. Another interesting one i ran across was i installed a WRT54G in a 4 story home on the second floor. Signal to floors 1-3 no problem but could not get it to the 4th. All it took was angling the antenna on 45's and the 4th floor could pick it up.

    Antennas - one side or both sides - are always good, as they improve both Tx and Rx signal.

    In your case, and to stay low cost, I would experiment with a parabolic reflector on the AP, and/or the PC (if the card has an external antenna) first, and see if you get decent signal improvement.

    Another option might be to get a short pigtail extension, and see if you can relocate either of the antennas slightly. Pigtails however, tend to be just about as expensive as an antenna, so borrow one maybe, and see what you get.

    As ifican mentioned, houses/walls, and throw in signal absorption/reflection, are not created equal.
