The newly rented house is wireless internet, wireless router in the living room, just bought a USB w

Something went wrong with the room! It's your room that has a stronger screen! So the signal is poor! Try to open the door and bring the computer close to the door!

Please have your wireless router, and the brand and model of the wireless card! And the room structure? Thank you.

Use an external USB cable, leave the wireless network card in the living room, and make the USB cable longer! That line is not expensive.

From what you described, I can rule out the problem with the wireless card, because on your roommate's machine, the signal is full; I guess the biggest problem is probably the problem with your software, the driver is the most willing.

Good landlord, what brand of router should be matched with what brand of wireless network card, whether there is a support protocol, but also depends on whether the router can support this protocol, the two should be consistent, the signal will be stable.

The walls are too thick and the signal is blocked.

The transmitting power of the wireless router is too small, so it is recommended to change to one with strong wall penetration.

The performance of the wireless network card that comes with the laptop is very good, and the wireless network card you buy for desktop use should not be as good as the original notebook, so the performance will definitely be poor.

Also, have you updated the driver of your wireless network card? Maybe it will work better.
