I have had this problem for a while. I have a linksys g router security enabled . The lap top (win xp pro sp3) sees the router but can't connect. Windows cant repair the connection but the wierd thing is , in the four months that this has been happening there was one day where it did connect automatically and stayed connected for about 4 hours. So it does work but thqt was the only time and that was a month ago. I checked to see that use proxy was unchecked and I reset sucessfully winsok but I still cannot connect. :thumbsup:

i would check the router settings and disable security until you have it working. when all is good add security.

Thanks for your reply. I have done all those things, even with a tech person at my side- to no avail. It did work one day for aobut 5hrs and I wasn't even trying to log on to the net- it just did it automatically exactly when I don't know but at some point I noticed I was connected so I surfe for the next 5hrs , closed up for a while then tried to get back on and it has been the same old story since- can't wirelessly connect.

How far from the router are you when trying to connect? If you move closer (in the same room) will it connect?

Thanks for your reply, strolln, yes I''ve tried a room away and right next to it, when it did work that strange day, lap top was on main floor and router was in basement so it can service that distance. As I said , laptop wirless device does see the router but windows can't connect.

There are a couple of things that your need to consider.

- Distance as it was already pointed out.
- Interference , most 2.4 Ghz devices would hamper your signal thereby nullifying your association to the Access point.
- The number of wireless network available that you can see, remember there are only 11 wireless channels, ( 13 if your in EU or Japan ).
- Obstructions between your access point to the wireless client -- Brick walls, wall insulators, glass etc.
- The type of security setup on the router. The farther you are from the router the less security should be used.
- Windows Wireless Zero Configuration is often a dud, try using the wireless utility employed by the machine, they work much better.

If you have already put these thing into consideration please post other information that may be pertinent.

-- How many wireless devices are there, theorytically a wireless access point can handle 32 wireless connections at once, but that is a controlled environment. So they don't really work that much in the real world.

Ok. Since you have already considered that try the following.

Isolate your network adapter. Turn off the wireless router.
Set up an adhoc network as a testbed and let your computer connect. If it connects the WLAN NIC is ok.
Try connecting to another public network and see if it works.

Now check your wireless router.
Powercycle the router and see if that helps.
If not reset your wireless router and work your way back.
If it still fails flash your routers firmware.

BTW you might want to check for signal issues by using wireshark or netstumbler or another other utility.

Thanks kennzsniper. I have powercycled the router but isolate my net work adaptor etc is a bit above my head. Could use a little more instruction there. Or point to where I can learn. Sorry for the time its taking me to reply but I am short on time till Tues. Work issues.
