无线路由器在电脑使用网线直接连接时，宽带及设备正常情况下，上网速度基本与宽带开通速度相同。
而使用手机、笔记本等无线WIFI连接时，则有时会发现其网速会比电脑网线直接慢很多，这是因为以下原因。1 signal attenuation of
the wireless signal when passing distance, obstructions and other factors continue to increase, will continue to be attenuated, resulting in speeds would therefore more slowly.
To solve this problem is to be solved by increasing the router.
2 wireless bandwidth limiting
stage home wireless WIFI 2.4G and 5G, respectively the two modes.
General wireless router (non dual devices) are 2.4G mode, which the largest channel bandwidth of the wireless network "40MHz", operating in this mode, the speed is generally about 20-40M, less if the wireless connection devices speed is not affected, the basic equipment on the Internet at the same time. However, when too many connections 2.4G mode WIFI signal equipment, Caton phenomenon occurs. 
5G wireless network mode maximum channel bandwidth "80MHz", operating in this mode, the speed can reach 60M and generally above. 
Thus, when buying a wireless router is recommended, with purchase device 5G preferred mode of operation, and when connected, the signal source is connected 5G wireless Internet access.
