In this case, the dual-band router is mostly turned on dual-band, but dual-band fusion is not enabled. Many routers now support two bands of 2.4G and 5G, and then there are manufacturers to promote the concept of dual-band integration. Under normal circumstances, one of the two wifi will be 5G on the table after the name, and the other will default to 2.4G. 5G is faster, but less capable of penetrating walls. The advantage of dual-band fusion is that the device automatically selects the frequency band according to the signal strength of the network.
In fact, turning on dual-band fusion is not recommended. In my actual experience, it worked poorly. In the case of going through the wall, 2.4G signal strength is higher than 5G, but 5G is actually faster at this time. You are advised to disable dual-band fusion and manually select the option based on the actual situation.
Two WiFi names appear on the router, you can do nothing, indicating that your router is a dual-band router. The dual-band router has two bands, 2.4G and 5G. According to their own needs. If the room is larger, you can just turn off the 5G signal. Use the 2.4G band directly, which is conducive to your wireless router signal transmission. The room is relatively small, and you use 5G directly, which will be conducive to your better use.
Will not strengthen, automatically select the signal is good, to set the phone, most mobile phones have this setting. What are you ultimately trying to achieve
There will not be this situation you said, the route only one landing, two wifi names are normal, a 2.4G a 5G band, the network speed problem you see if your setting is correct.
