    House eats wireless signal

    I just moved out of the barracks into a house. When I lived in the barracks, my DLink DI-624 worked great. The barracks was nothing but concrete, steel, and high voltage power; the worst conditions possible for wireless. Needless to say, I got better range there than I do now in this house.

    The house I am living in now was probably originally built in the 1940's. I have it set up in the living room where I can only get maybe 20 feet of range. Normal excellent connection is about 10 feet. Also, if anything gets in the way, I loose my connection. If someone stands between my laptop and my router, the connection is gone.

    I've checked the antenna on the router and it seems fine. I also ensured that the router is putting out 100% of power which it is. I don't think that there is anything wrong with the hardware. I think that the house is eating all my wireless signal. I've moved the router all around (trying to get it higher or in a better position) and nothing seems to help. I'm wondering if a high gain antenna will be able to punch through this signal eating monster that I have to live with.

    Any suggestions?

    Do you have a microwave, or a wireless phone in the 2.4 Ghz frequency?

    If it was built in the 1940's you may just have really bad EMI from old wiring.

    Bad wiring could be it. This house only has one grounded outlet (three-prong) in each room. All other outlets are regular two-prong outlets.

    There is siding on the outside of the house but wouldn't that make it so the signal outside the house suck?

    Microwave is clear in the other end of the house (rarely in use) and there are no cordless phones hooked up.

    It (metal in the walls) still would have to be BETWEEN the router and the computer to make any difference (even keeps noise outside).

    Test with another router/wifi card in the same house. Could be a nearby source of noise (check s/n ratio with netstumbler), could be your equipment got damaged during the move, could be the power in the house that carries static...

    I just tested with my girlfriend's laptop (802.11g built-in). She gets and even worse signal that I do. I have both laptops sitting side-by-side on the floor. They are approx. 6 feet away from the router which is sitting about two feet higher than the laptops.

    Windows and NetStumbler are giving my contradictory readings.

    Windows
    My Laptop: 5 bars (excellent)
    Her Laptop: 2-3 bars (low to good)

    NetStumbler
    Code:
    Laptop    Speed   SNR   Signal+  Noise-  SNR+   Maker
    ------    -----   ----   ------  ------  ----   ------
    Mine      54Mbps  16-17    15     -100    21    DLink
    Hers      54Mbps  25-34   -60     -100    40    Compaq
    Anyone wanna try to figure this out?

    No other APs are seen in NetStumbler. The router will not let me change the channel. It's locked on 6.

    That's because your router is setup to use Super G mode. You can disable Super G by going into the router and going to Advanced > Performance and select disabled for Super G. You will then be able to change the channel. Change the preamble to short as well. If it is set to short then switch it to long. Make sure you have firmware 2.42 as well, you can check by going to Status. If you don't have firmware 2.42, go to http://support.dlink.com/ and find your product and download firmware 2.42. Then log back into the router when you're wired to it (dont do it wireless) and go to Tools > firmware and upgrade the firmware there.

    (Firmware versions I'm speaking of coincide with a Revision C of your router, you can find the revision underneath the router's sticker, H/W: XX, although the steps are the same if you had a Revision B)

    One other thing, the DWL-G650 utility has problems reporting signals if you're using the D-Link utility, the Windows utility reports the correct signal/speed. But don't let the signal strength fool you on the D-Link utility.
