Hi all i have a network cable run of about 30m which has a cat6 cable ran it at the moment. It will only connect at 100mbit i have tried different devices and tried a cable tester which is showing all pairs / cables working. Any ideas? Thanks!
 
Is the cable of decent quality?

Are you 100% sure it's connected correctly? The cheap cable testers can only tell you much. Could you post pictures of the connections?

Hi im not sure it is very good quality honestly. Its a pre-terminated cable so the connectors dont really show you much.

Its connecting a N55u router (has gigabit ports) to a gigabit switch upstairs. It does run close to some power cables could they be the issue?

Thanks.
 
Hi Mr Pink. Its a completely un-managed switch so unfortunately i cannot manually set it at all.

I did try plugging it into my computer rather than into the switch. The computers network card light did not come on for about 20 seconds then it connected at 100mbit. I can only guess it was trying to connect at gig an failed.
 
If the cable tester shows each pin is correct (check both ends of the tester, might be crimped in the wrong order.

If they are all fine, I'd try putting a crimp tool on it to 'recrimp' the metal pins into the wires.
 
Is the cable new/old? Have the Ethernet ports been empty for a long period of time?

Reason I ask is that the connection pins on the cable as well as in the port can get a fine layer of dust on them which can cause a not so solid connection.
 
Hi thanks for the reply's. I have a crimp tool that i got with my cable tester, i used it on the connectors even though they were already crimped / sealed. It seems to have done the job! have a gig connection now! :)
