I cannot have a wireless adapter installed even if I install it!

Hallo everyone,

I am just having a big problem with my Internet Connection(Wifi Adapter). Let me explain you how I got here(it might help you understand the problem better). It was Friday evening when I have just finished studying and getting ready to play video games with my friends! But when I boot up my laptop I saw something, my laptop could not connect to the Internet through wifi. I tried so many things( expect deleting the installed drivers) to actually understand if the problem was in my.laptop or not. After.having done lot of things I thought that the problem was in the wireless adapter. I deleted him and I installed a new wireless adapter which I had downloaded from the Acer website. As it turns out I was too wrong. The problem was in the router. We changed router but nothing changed for me( the other devices like phones and computers could join wifi while I couldn't). Till then I haven't been able to access Wifi through my laptop. And now most of you will be thinking "if you cannot access Internet through wifi then try through ethernet". Let me save you some.time. My little sister had already broken the ethernet port!! When I go to device manager and network adapter the only adapters I see is for ethernet and no wifi and I have downloaded all of the Acer wifi drivers I could find! If anyone can help me please let me.know on the comments section.

Thanks in.advance

Bill
