![什么时候应将噪声安全系数视为好或坏?](https://linux22.com/image/1523185/%E4%BB%80%E4%B9%88%E6%97%B6%E5%80%99%E5%BA%94%E5%B0%86%E5%99%AA%E5%A3%B0%E5%AE%89%E5%85%A8%E7%B3%BB%E6%95%B0%E8%A7%86%E4%B8%BA%E5%A5%BD%E6%88%96%E5%9D%8F%EF%BC%9F.png)
我搬到了新家,并且我拥有与以前完全一样的 VDSL 服务,但我遇到了速度下降的问题,有时我可以获得全速 20 Mbps,有时我只能获得 2 Mbps,因此我查看了路由器中的连接详细信息并将它们与我的旧连接详细信息进行比较,我发现下行噪声安全系数比以前高得多。
DSL synchronization status:Up
