我的网络每隔几分钟就会断线（断线时间不固定），DSL connection is down. 然后又连线，中间会断几十秒。我记录了ROUTER里的一些断线记录，如下：

01:20:49 (since last boot) xDSL linestate down
01:21:16 (since last boot) xDSL linestate up (downstream: 13996 kbit/s, upstream: 926 kbit/s; output Power Down: 19.0 dBm, Up: 10.5 dBm; line Attenuation Down: 19.5 dB, Up: 8.0 dB; snr Margin Down: 8.5 dB, Up: 7.5 dB)


01:21:54 (since last boot) xDSL linestate down
01:22:23 (since last boot) xDSL linestate up

01:24:16 (since last boot) xDSL linestate down
01:24:43 (since last boot) xDSL linestate up


下面是一些ROUTER信息：

急问，如何能让DSL一直连接着不要每隔几分钟断一次？

Maybe the link quality is not so good.
