Insisting on using your own term without precise symptoms only serves to create confusion making it hard to help you.

Instead of repeating your problem, please just give us the precise symptoms. The best way to solve a problem is to take it step by step -- the scattergun approach is much slower.

When this happens:

  1. Open a command window and run "IPCONFIG /ALL". Post the _exact_ output here.

  1. Cable your computer to the wireless router. See if you can access the router status screen that way.

Things to try:

  1. Turn off all wireless security. See if the problem persists.

  1. Uninstall and then reinstall the wireless adapter. Check the manf website and make sure you are using the latest driver.

  2. Try a different wireless adapter. See if it exhibits the same problem.

All that other information isn't really helpful.

Hi. Try resetting your router and starting over, leaving DHCP on. Set your wireless adapter to get addresses and DNS automatically. Set your DNS in the reouter setup page instead of the client?

Run it with WPA off for a while. See if it works. Turn WPA back on and see if it works.

I want to update the latest situation: First, i want to name the problem: It's a wi-fi "drop" occurs between adapter and router occasionaly.

After working well couple of days, wi-fi drops although it seemed "connected" in XP's system tray with no notification of disconnection but i can realize "drop" by looking router's client list.

But the question is: Why does drop occur although router's/adapter's positions and distance are the "same" when like operating in a stable enviroment?

I can operate stable for a long time/days/weeks, but one day; wi-fi drops though there's no placement or setting change for router and adapter also.

So, can we say: The drop is caused by "external" factors like signal interferes and noises?

Possible interference. Possible problem with DHCP lease renewal.

Possibly.

Hi Mr. Navas and thanks for the reply, I have to know this also: What are the stability thresholds of Wi-fi's "signal levels" and "noise levels"?

For example, when signal is worse than -60 or -65dbi, i get drops, when it goes around between -40 and -50dbi it's much more stable with no drops.

Is there a tested or accepted threshold value for signal and noise level to have a maintained Wi-fi operation?
