can't connect to wifi

[xX4m4zingXx]

Hello,
I can't connect to wifi.
My pc shows the icon with a yellow star.
When I try to connect I get this error:
Can't connect to [My wifi name.].
Lan works perfectly fine.
Yesterday I still had connection but now I don't.
I got these network adapters:

My laptop is an Acer Aspire 5750g 64-bit.

Well; first for something simple; I would try removing all 3 network adapters shown; reboot; then re-add/re-install the adapters then reboot again and see if that solves the issue for you. If not; try power cycling your router/network equipment including any routers and modems. Unplug them, wait about a minute or so; then plug them back in with plugging in the modem(s) first; letting those boot fully; then plug the router(s)/network equipment back in and let that boot. Sometimes what happens is they just need a simple reset as thats just what happens with computer equipment from time to time. If neither of these work; post back and we can go from there.

Turn your other wifi devices off that connect to the internet. Left click open network sharing computer icon. Choose your internet connection, select connect. Do not type a password there. Now hold your wps button until it lights up, then wait. Light will turn off eventually.

If the wifi is working now, don't do what I said in my other post. Most likely that your internet provider causing wifi to drop.

I didn't realize that.


Each wifi device is assigned an dchp or static ip address
So it possible that two devices are using the same dchp or static ip address is conflicting.
I don't know how many wifi devices can be connected to a router at one time.

Turn off all your wifi device including the computer.
What you need to do, is do a full factory reset on your router press your reset button and hold for 30 seconds or more wait to the wifi internet connection comes back steady light. Then turn on your computer left click open network sharing computer icon. Choose your internet connection, select connect. Do not type a password there. Now hold your wps button until it lights up, then wait. After connected, stop go into your modem settings using your web browser and change the default password (your default password & user name is usually in the router instructions). You can leave the computer on. Turn on each wifi device one at a time, you might get a warning the wifi is diabled, ignore that. For each device go into the settings and select "WPS" maybe be called something different in Netherlands. Now press the router "WPS" button until the light comes on. After you are done with one device, turn on the next wifi device it is ok to leave the previous devices on after you are done.

Also, if one or more device goes ahead connect, go ahead a reset so it assigned a correct dchp or static ip address.

I hope explained that good and I hope I am right.

Ok, I can try that, but I was just at a frinds house with my laptop and I also wasn't able to connect to theirs WiFi. I really have no idea why this is happening.
