【求助】六十多米的网线信号也会衰弱到无吗????

gavin84

昨天从朋友那里拉了一条网线到我宿舍,长度大概就六十多米,不超过六十五米.
网线就是在电脑城买的那种九芯的(有一根是铜线),有一层好像是锡纸一样的屏蔽层的.
问题是接好后基本上不了网.中间有一次可以上,时间不超过一分钟.
电脑的设置没问题,我就想问一下,六十多米的网线信号会衰弱到无吗(我一直认为是百米之内,我朋友以前用过九十多米也没问题)?还有就是有屏蔽层的网线质量会真的好一点吗?
补充一点路由是水星的.  奉上一点分数略表心意.

另外我刚刚听说 [有屏蔽层的网线只合适做近距离的连接] 是不是真的呀
55555555555
我的银子呀

CDMA密

测试一下网线有没有问题吧,60多米不会的,我最长拉过120米的,100米以内基本没啥影响

shaoxiang

最近的电信楼道交换机到我家就110米左右
我用了几年了没问题，普通线

zygxdxd

我正打算接个100米的。不会有问题吗？

gavin84

楼上的,我建议你用普通线,就是那种最便宜的.
我一时头脑发热买了有屏蔽的.唉......

sunspring

与屏蔽线关系不大.

检查:水晶头(及线序是否规范),网卡,路由.

liven168

检查线有没拉断,以前我就断过一次,线没走好,用专用设备查

foxwwh

是不是没有严格按照T-568A或者568B接线,我曾经没有按照标准压线,居然不到10米就不能联通了!!!PING能通,也经常丢包,换过来就可以了!!!!

不严格按照标准接 好像1到2米范围就可以用的

guomuyi5262

感觉应该是路由的问题!!

gavin84

先谢谢楼上各位
明天再来

cqsc

看看线的顺序接对没有;;;;;棕--棕白--绿--蓝白--蓝--绿白--橙--橙白

wokin

应该和信号强弱无关吧?我看ping值挺低

馅饼

看看线的顺序接对没有,l另外看看网线里面有没有铁丝冒充铜线

limonet

我可以肯定是线的问题,问题就在屏蔽上.我曾经做了一根5米不到的屏蔽线,结果经常不稳定,换成普通线后OK.

yunxiaochuan

应该跟线有关系吧...
我曾经有一段线,用普通户外网线接的,大概有五六十米,就有问题.在中间有模块,在中间接个本本,往两端PING都没问题,但是在一端往另一端PING就经常LOST....
觉得有可能是网线本身影响了传输距离...
个人判断,仅供参考...

常爱常受伤

我试过300米，线好没问题的。

abyssabyss

屏蔽双绞线是没有问题的。估计主要是线序的问题，另外用测线仪测一下看看是不是灯都亮。

水晶头线序两面要完全一样。用568B或者A线序

羽雨

*.*lll 记得曾经看过介绍说屏蔽线在一般环境下效果不但起不到屏蔽反而效果不好，用非屏蔽线吧！

gavin84

补充一个情况
连上的时候,路由的灯在狂闪

gavin84

应该是屏蔽层的问题了,
测线仪测的灯都是亮的,电脑设置也没有问题
我把IP改成和路由或者其它机器一样时会显示发生冲突

hl968

我试过用3跟20米以上的线，通过普通连接头连在一起，没有问题。
都是普通线，单位网络拆除后留下的

gavin84

先谢谢楼上各位.上网问题已经解决.
我另外找了二根二十多米的请人连接起来.网速还可以.

那根六十多米的朋友拿去试了下却可以用
在我手里它就是不通.

cyzokok

我刚拉的100M现在用着没问题啊.试用几天下来开网页很快,下载也正常,

cyzokok

屏蔽线弄不好反而会成最大的干扰源!!
