北京联通光猫改桥接之后间歇断网

[black201w]

今天上午刚改的桥接, 路由器是 OpenWRT 的系统, 大概 10 几分钟断一次, 问问老哥们有没有遇到过相同情况

贴一下断网发生时的系统日志

之前有段时间联通 2 小时左右会断网重新拨号，打电话师傅来重新注册下光猫就正常了

[wd]

你这看着是你这路由器有问题啊 那些错误 permission deny 还有 no space left

[Cipool]

虽然不是北京联通，但是也遇到过类似情况，打电话报修，师傅带来个新的中兴光猫就好了

No buffer space available，很可能是路由的问题，换个路由先试试

@wd
@brMu 尝试了使用电脑直接拨号, 没有出现掉线的情况了, 但是这台路由器之前桥接移动的宽带完全没有问题, 而且路由器的存储空间也没有满, 完全找不出问题出在哪里, 裂开

我插上路由交换机监控就延迟特别高，拔下来就正常，不知道咋回事，移动的直接说不会弄，因为我拔下来正常他们就不管了，我操

找到问题所在了, 是固件某个版本的 bug, 重新编译最新固件刷入后解决了
