Solve the Problem of connecting wireless wi-fi network to macbookpro, macbookwi-fi
After a long time, I tried all the methods on the Internet, and the ip dns and so on were ineffective. The Wi-Fi search network was displayed on the computer wireless network, but the router was not connected, the original reason is that my external usb 3.0 extended connection line, because the type-c extended connection line usb has a transmission rate of 5 Gbit/s, the frequency is 5 GHz, note that 5 GHz refers to the transmission rate in full duplex mode. The usb 3.0 we use is transmitted through transmission lines, and there are two sets of lines in the transmission line, the transmission rate of the two sets of lines is 5 GHz, that is, the transmission rate of a single set of lines is only 2 to 5 GHz. In this case, the 2.4 GHz wi-fi frequency sent by the vro is almost the same, so it is easy to interfere with each other. The external usb has a shielding layer, but the interface still leaks signals and cannot be truly shielded, after all, you need to use a wired interface. Therefore, as long as your external usb and Wi-Fi signal frequency are inconsistent, using a 5 GHz router will not produce signal interference (buy it if you have money, after all, the external wiring is still very useful), or directly unplug the external type-c line. The original conversion interface of Apple has a signal shielding function, which can avoid signal interference resulting in unstable Wi-Fi or direct link failure to the router.
