I can't connect my Sony VAIO laptop to any WiFi. My laptop can detect the WiFi but only shows 1 to none bar of WiFi even it is in ranged and other devices (laptops, phones) have no problems. When I try to connect it, it always shows: "Can't connect to this network" . I tried to install new and updated network adapters (Broadcom) but these didn't help. I searched for forums regarding to my problem and did everything but I think my case is a rare one. I even reset my laptop and windows. (It was from windows 10 now windows 8 due to the reset) but it didn't help.
My laptop works fine if it is connected via Ethernet cable, but now I don't have access to Ethernet cables (I'm living with my sister's) and I want to use the internet via WiFi.
Everything is turned on.: Wifi. Network adapters. My laptop doesn't have physical wireless network switch. (I think so)
Please help me. I will be cooperative.
I had this problem since 1-2 years ago. Before that everything worked fine.

Update: my laptop is now connected to the wifi that has only one bar and it is very slow to the point it is irritating.I think my connection to the wifi won't last long because this already happened before and the problem always keep coming back.

Does buying USB wireless adapter will have a 100% guarantee that my laptop would be able to connect to the wifi properly without any problems? I think this would be my last option.

@reedo_43 yeah! Should have thought that first!
I've just bought a USB WiFI adapter and all my problems are solved! But if anyone could suggest solutions that would be great! I don't want to rely to the USB WiFi adapter if there will be a another solution.
