Why does Windows 7 reject wireless routers?

            1. The wireless router is faulty:
Is the wireless router's wireless function malfunctioning? I tried to connect to the wireless network in Windows Vista and found that the wireless connection is very smooth. No way, I had to find a friend who also installed Windows 7, wirelessly connected to the author's wireless router with his computer, but found that there is also the problem of not being able to connect. Therefore, the author judges that the wireless router may conflict with the wireless network system of Windows 7. I replaced a Huawei 3Com wbr204g wireless router for testing and found that the Windows 7 system is smoothly connected to the wireless router and can access the Internet. It seems that the author's wireless router is really a problem.
Since the wireless router is not compatible with the Windows 7 wireless network system, does it mean that it must be replaced? In order to save money, I decided to find the relevant information of the wireless router to further troubleshoot. On the management page of the wireless router, I found that its firmware version is 4.2.0 Build 081225, which should be released in December 2008. It is relatively old, and Windows 7 was released in October 2009. It seems that it may be wireless. The router firmware does not support Windows 7. On the official website of the wireless router, I downloaded the relevant firmware updated on July 30, 2009. After upgrading the firmware, I found that the firmware version of the wireless router has been updated to 4.2.0 Build 090730. Can updating the firmware solve the problem? After setting the network parameters, the author's Windows 7 no longer refuses the wireless router, and finally can surf the Internet under Windows 7.
2, the problem is:
In addition to the hardware system, the wireless router also has a software system that directs hardware work — — firmware. Users generally manage wireless routers with a simple web page mode, and it is likely that the web page is actually the outer shell of the wireless router software system. When the Internet is unavailable, the user can check the working status of the wireless router through the management page of the wireless router. If the wireless router is working properly but cannot connect to the wireless network under Windows 7, it is probably the software system of the wireless router.
