要 crossover 呀

http://en.wikipedia.org/wiki/Ethernet_crossover_cable

An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly. Normal straight through or patch cables were used to connect from a host network interface controller (a computer or similar device) to a network switch, hub or router. A cable with connections that "cross over" was used to connect two devices of the same type: two hosts or two switches to each other. Owing to the inclusion of Auto-MDIX capability, modern implementations of the Ethernet over twisted pair standards usually no longer require the use of crossover cables.

應該唔使 crossover 的,家陣全部都適得自動認 pin 用普通線都通到,
同埋 crossover 係電腦去電腦先用,電腦去 router 係用普通 straight through 線,段野有寫
樓主問題似係條線質量不佳多啲,長距離訊號差致上唔到 GbE,結果 router pc 以為斷線

    得 wan port 有 auto mdi 所以 lan port 去 pc 唔通

樓主夾過條線啦

普通Cable tester只可以test條線通定唔通, 但唔可以保證行唔行到1G咁高頻率, 要行咁長最好就係買過條靚線

40m cat5e $138一D都唔平
如果以一箱買再除開, 呢個價錢夠買cat6
