Wi-Fi not working on Aspire 5920G

hello guys i need some advice. today i have open my laptop back to blow out the fan with kompressor and when i put the back of the laptop back and turn on my laptop. i have seen my wifi isnot working. i have open my laptop back again and reinsert my wifi card but it still dont working. any idea?

i have the same type of laptop like triturbo an acer 5920g.
and another question what is this cable on the picture that i point on it:

 

It could be silly question, but have you tried to press the Wi-Fi button?

That's the cable for right-hand-side USB/TV board.

BTW it's not the right place for those kind of questions

 

i tried to press the wifi button but nothing? the wifi card can be wrong? so there is any chance if i buy a new one it will work?

 

It wasn't. I moved it and created new thread.

 

@impish - Go to Network and sharing center -> Manage network connections and check if your Wireless network is enabled. If it's disabled - enable it, if it's enabled, disable it and then re-enable it. That's in case the Wi-Fi is still recognized by the system (right click on Computer -> Manage -> Device manager -> Network adapter), if not you'll have to buy a new one, though I don't know what is the reason so this would happen in first place.

@downloads - That's more like it, thanks

 

Well first of all are there other devices that are connecting to the wifi network. If you don't have ant other devices reset your router and test it again (that would eliminate the signal from the router being the issue). Routers need to be reset all the time. it you determin it's not the router then follow the steps on the other posts.

 

Hello!

I have posted like 1 weeks ago about my wifi is off because of something. i try to reinsert the mini wifi but its still off. i checked everything and now i make photos about the wifi and i share it because maybe someone maybe a mechanic see something on the photos and i didnot want to buy another wifi mini pci card to my laptop if the maybe the slot has a problem and not the card.



there are some abrasion or discoloration at the screw's holes. i reinsert it 3 times with carefully so i dont think the screws do them.

pls answer fast because i am getting nervous because of the internet cables :S and i dont want to buy an usb stick for wifi :S

 

You could either get a card from another machine and try it (they are usually easy to access and user serviceable) or go to a local shop and ask if they have a spare you can try .

 

the problem is i dont have another laptop with almost the same wifi card and i know in the local shops there isnot any.

 

When you say you don't have any almost the same? You dont have any mini-pci express ones?

 

i mean i dont have any other mini wifi card and i dont have any friends or person who have latop with that kind of mini wifi card and if they have i dont think they are happy if i take it out of their laptop to try it.
