A dedicated 3070 wireless network card is required, because the signal quality is higher than -70dBI, most routers cannot be connected or there is a large area of packet loss after connection, resulting in unusability; If you are satisfied, please give points!
If the replacement of the network card is the same five brands, it should be a problem with the quality of the network card of this brand, if the replacement is a different brand or the same problem, there should be a signal interference source nearby, it may be your electrical appliances, or the influence of the other party's door and window switches.
Then you must know this WIFI password, and if you don't know the password, there is no possibility of relay. >>>More
Replace a router with a more radioactive one, or put the router in the study.
Check the router's wireless settings to see if there is any power adjustment. >>>More
Hello, your situation is caused by the router's signal coverage is too small, replacing the router with 6 antennas may not be able to help you solve this problem, if you want to solve it completely, buy another router, pull a network cable to the vicinity of the bedroom, and then the wireless signal name and password of the 2 routers are set to the same, you can roam wirelessly. Won't set up can ask me, professional.
