Yesterday, I noticed a serious decline in my signal strength from my Linksys Wireless-G router. Normally, I get 3-4 bars in my bedroom but I only had 1 and internet speed was severely reduced. I checked a few settings, although I wasn't sure what I was doing and reset everything back to the way it was, and the signal went up to 2 bars.
I turned it off and went to sleep. Tonight, I come home from work and turn my computer on and I get no signal at all. My computer recognizes I have a WiFi connection but cannot connect because 'Windows did not receive any response from the Wireless Router or Access Point''...
My computer works fine connected with a cable to my router, and my mother's laptop works flawlessly (and did not have the signal problems last night like I did). I've been through a few googles of what to do and nothing. Gateway isn't offering tech support without a hefty toll and I'm stuck being attached to a 5' cable.
I did update the driver on my wireless card and all that jazz. I did spyware/virus scans, about 20 reboots, reinstalled drivers/cards out the wazoo, and I've tried to 'diganose the problem' a thousand times and Windows has nothing.

Re: Laptop connected to WiFi yesterday but now cannot
Try rolling back to the previous driver and also uninstalling and reinstalling the last driver update try this last in safe mode (try one thing at a time and test)
check if there's a firmware update for your wireless lynksys router.

If everything is installed correctly, thing that you might want to check first are:
* Location of the desktop or laptop . It's possible that it might not be getting a strong signal from the router.
* If the wireless adapter has an antenna, make sure that it's in a spot where it will be able to get a good to excellent signal strength. Make sure there is nothing that can block the signal from the router like, walls, tables, and other furniture that can block the signal.
* Do you have other computers that can pick up a the signal of your 2wire router? If you have a laptop that can connect to the same router, bring it in the spot where the none working computer is, see if the laptop will have the same issue.
These are things that you can start checking before going to more technical stuff.
There are a few things that can cause you to lose wireless connection with your wireless router. 1. Weak signal strength, check the signal strength on your wireless card. If it is weak move the wireless router away from walls and if possible locate the wireless router higher up. 2. Have you secured your wireless router from people near your from unauthorized access? Ie. change the default password, setup encryption use WPA2 or WPA, change the default SSID, and turn off SSID broadcast, and for added protection, enable MAC address filtering which allows only the MAC address/es of your wireless card/s to connect to your wireless router. 3. You could be getting interference from electrical sources such as air conditioners, arid welders, washing machines etc. If so the power supply to the wireless routers and computers etc should be connected to a surge protection power board, better still connect your computer equipment to an UPS (Uninterrupted Power Supply) 4. Check the channels of the wireless routers and access points in your area and change the broadcast channel on your wireless router to an unused channel or one that has the weakest signal strength. This will minimize interference with your wireless router from other wireless routers and access points in your area.
You may find this strage but we often get the same problem. It usually is because the security password is not exactly correct. DELETE the connection and then re-detect it and and make sure you insert the password correctly. Hope it works ....
Try to remove the preferred networks on your Presario then try connecting again. If you have wireless security enabled on your router, you have to enter that. Make sure that the settings on your router is the same as your wireless adapter so that they can synchronize.
If you have difficulty with that, just ask me and I'll answer as soon as I can.
Disable and renable wireless card, even try unistalling the wireless card and reinstall it. update driver for wireless card. then if those fail, put pc next to router if signal still bad then card needs replaced. If your ISP didnt have you power off the router for 30 sec then do so.
