Hi, my computer was just brought like a week ago, during the week I can connect to the wifi and surf the internet and play some online games. Then suddenly the wifi that I am using cannot connect to it and the laptop can't detect the wifi even though I have manually connected the wifi. I have try offing the wifi and back on but it wouldn't work. I also have reset the wifi it will didn't work. All my connections have been updated to the latest version. BTW I don't have a router.
