In this step, you will collect information about your wireless network device. The way you fix many wireless problems depends on the make and model number of the wireless adapter, so you will need to make a note of these details. It can also be helpful to have some of the items that came with your computer too, like device driver installation discs. Look for the following items, if you still have them:
Hộp gói và nội dung của thiết bị của bạn (đặt biệt là hướng dẫn sử dụng)
Đĩa chứa trình điều khiển cho bộ điều hợp không dây (thậm chí nếu chỉ có cho Windows)
The manufacturers and model numbers of your computer, wireless adapter and router. This information can usually be found on the underside or reverse of the device.
Any version or revision numbers that may be printed on your wireless network devices or their packaging. These can be especially helpful, so look carefully.
Anything on the driver disc that identifies either the device itself, its “firmware” version, or the components (chipset) it uses.
If possible, try to get access to an alternative working internet connection so that you can download software and drivers if necessary. (Plugging your computer directly into the router with an Ethernet network cable is one way of providing this, but only plug it in when you need to.)
Once you have as many of these items as possible, click Next.
