    Hi,
    I have a Toshiba M45-S359 notebook laptop. About every 20-30 seconds, the wireless connection drops off (and immediately automatically reconnects). This is not a router issue because I tried 2 different routers (Linksys and Netgear) and also the wireless connection is perfectly stable on the other laptop I have.
    There are no interference issues either because it happens even when I have the laptop sitting very close to the router.
    Any suggestions/advice? Thanks in advance.

    Check the WiFi setting on your notebook. Try setting it to 11 mbps or 54 mbps (if it supports 802.11g) instead of Auto.

    Go to Start -> Control Panel -> System -> Hardware -> Device Manager.

    In there, look for your WiFi module (for example, Intel PRO/Wireless LAN 2100). Right click and select Properties.

    Go to Advanced. There should be an option for you to change the data rate or transmission mode.

    Under Intel Pro/Wireless 2200BG Network Connection, I found the Wireless Mode module. It is already set to use the default value (802.11b and 802.11g), using both 11 Mbps and 54 Mbps data rate. I did not see the "auto" option.

    Additional info:
    Ad Hoc Channel is set to 802.11 b/g, Channel 10
    Intel throughput enhancer is enabled
    Preferred band is using 802.11g as default

    Thx.

    Well, force it to use only one... Either 802.11b or 802.11g. Try 802.11g first.

    For some reason, that doesn't work either..
    Thx,

    Try disabling the Intel Throughput Enhancer.

    Tried updating the drivers?

    Yeah, try updating the WiFi driver. Check and see if your router has a newer firmware too.

    Hmm.. The list isn't mind-boggling actually. In fact, it's very easy to understand. It's arranged by date, from the most recent at the top to the oldest files at the bottom.

    The latest Intel WiFi driver is Intel 802.11a/b/g/n, a/b/g, b/g PCIe Mini Card driver for Windows XP (v11.5.0.32 Logo; 11-29-2007; 5.92M)

    Thanks for the driver. I ran it and restarted my laptop but I am not sure it's installed. Under the Network adapter properties (under device manager), under Driver, it says Driver version 9.0.4.37, dated 7/25/2007.
    I could not manually update the driver because it is looking for a *.inf file which cannot be located inside the zipped driver file. The way the zipped driver file works is that when I double-click to open it, it directly runs the setup - i.e., it does not show me the contents of the zipped file...

    You need to extract the zip file first.

    Well, if it ran the setup, then it should be just fine.

    Oh yeah, good idea! There should be an option in Device Manager to turn off the WiFi when it's inactive to save power. DISABLE that.
