My acer aspire 5733z won't connect to the wifi in my main bedroom for some odd reason. 2 days ago i went and cleaned out the fan, closed the laptop back up and turned it on, and it was working fine. brought it back to my bedroom and it suddenly won't connect to the wifi, and if it does it says that it's an unidentified network even though it does connect to it. After a few minutes it losses connection. I've been connecting it to the Ethernet and it would work, and the wireless says that it now connects to the wifi. Right now I'm in the living room and it can connect to the wifi, but if i go to the main bedroom it can't, and ill have to go connect it to the Ethernet again to get the wireless to connect to the internet.
