Why can't the speed of mobile phones and laptops always go up? Most likely, the wireless negotiation rate is too low! How do I check it?
After the wireless terminal is connected to the wireless signal, the wireless network card and the wireless router will negotiate, and the general wireless negotiation rate is the highest transmission rate that both can support (for example, the maximum connection rate is 150Mbps when the 300Mbps wireless router is connected to the 150Mbps wireless network card), and the wireless speed test result is closely related to the wireless negotiation rate.
Common wireless terminals, such as Windows computers, Android phones, and MacBooks, can directly view the wireless negotiation rate, while Apple mobile phones cannot directly view the negotiation rate.
