本发明涉及通信领域，尤其涉及一种网络切换的方法及装置。
背景技术
家庭宽带的普及和路由器往5G(fifth generation，第5代)技术的发展使得家庭用户使用双频路由器或两个路由器组网的场景越发普遍，例如有如下的使用场景：
5G频段干扰小，上网体验要优于2.4G网络。而2.4G/5G双频路由器一般都是同时支持2.4G和5G热点。这时候容易遇到的问题是：假如2.4G路由器名称为AP(Access Point，接入点)_2.4G，5G路由器名称为AP_5G，用户优先会使用5G信号，由于5G覆盖距离短，用户走远后由于5G仍连着。除非用户手动切换到2.4G网络，否则即使5G的信号很差，但终端仍能检测到5G，也不能切换到2.4G网络上，从而用户上网体验很差。
发明内容
