    Hi I have a Sony VGNFS-742/W.

    The Wireless LAN was working fine for the first year but suddenly the range of the Wireless LAN is reduced to 5-8 meters. I have tried re-installing all the drivers and also tried the complete recovery of the system but nothing seems to be working.

    Please suggest what can make the wireless Lan function with normal range. The wireless adapter used is Intel(R) PRO/Wireless 2200BG Network Adapter

    Another thing to check is this: did you reinstall drivers from your CD and/or Sony's website, or did you use the latest driver from Intel? When it comes to Intel PRO/Wireless drivers, always use the driver from Intel. You can get the latest 2200BG driver at:
    http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=1637

    Have you added anything to your home that might be causing wireless interference? Any electrical wiring changes?

    All the other laptops are working fine within my house.. and my system doesnt work with any other router as well.. so it seems that definitely there is an issue with the wireless set in this notebook

    If everything else is working OK, you are likely having a problem with either the wireless card itself (hopefully) or the notebook's antenna wire (hope that's not it). Do any of your other laptops use an Intel 2200 card? If so, you might try swapping cards between notebooks to see if your Sony's connection improves (and, conversely, to see if the other laptop's signal goes through the floor). If it does, you'll probably need to buy a replacement card. If it doesn't...well...might I recommend a good PCMCIA wireless card?

    There really isn't an easy way to check the antenna, as far as I know, unless you like getting into the guts of your notebook. Generally, a faulty antenna is cause for RMA, since the antenna is usually (but not always) run around the LCD casing (e.g., disassembling to the point that you could check the entire antenna wire would involve dismantling your LCD, most likely, which would risk damaging other components). That's why I suggested tracking down a good PCMCIA wireless card if swapping wireless cards didn't improve your signal.

    PCMCIA wireless uses an antenna/transmitter coiled or hooked into the chunk of the card that sticks out of the notebook. Linksys, though I hate their routers, makes some very good PCMCIA wireless cards, as does Netgear.
