just setting up my laptop nw how to reboot wireless point
Thanks

what i would suggest is to disable the wireless network adapter on your computer and then restart your laptop and then enable it,

to do this follow these steps:
1- go to: Start> settings> control pannel> Administrative Tools> computer managment
2- then in the left hand tab click "device manager" and then go to "network devices" and rigt click your wireless adapter and click "Uninstall"

3- restart laptop

4- to enable the wifi adapter go to "device manager" (like in steps 1 + 2 and then at the top toolbar click the "scan for hardware changes" button.

that should sort out the problem. keep me updated

in that menu try expanding all the fields and looking for something with "WLAN" or "WIFI" in the name and post back what you find.


we dont want to uninstall "lan express adapter and marvell yukon ethernet "

you missed the part 802.11g, lol, yep thats the one to uninstall.
802.11g confirms that it is a wireless adapter

so uninstall ASIEEE802.11g PCI-E adapter

there is also a small tick box asking delete the software for this device do i need to tick it

yep thats fine this happens with vista lots of security warnings

now make sure you do NOT TICK the box, and click OK

we are trying to uninstall the device and then re install it after re boot so we need to keep the driver software hence we do not tick the box.

i have not ticked the box but have uninstalled now where is scan for hardware changes button in the device manager
Thanks

in device manager window select "network adapters", and at the top of the windows (toolbar) click on "Actions" and then click "Scan for hardware changes".
do this after you reboot.

Thank for your help

Are the two laptops in the same location?, if so sounds like the weak signal one is faulty, possible the internal aerial connection is shot.
The fact you have detected a signal points to the chipset actually working but quality of signal is inferior.
Perhaps try shutting off the one that is connecting first to check if it is actually that that is interfering, though not something I have ever heard of.
Check the set up of the router and try an alternate manually set "channel" if its on 6 try 12 etc.
