1308002 2012-10-21 23:15:00 So a few months ago, we got a structured network installed in the house (we got the house re-clad, so decided to do it while we could) and all was well with the world. Gigabit networking to any device that could use it.

A little while ago, I decided to do a bit of a tidy up at the patch panel. My initial setup was pretty quick and dirty, and didn't look very tidy. That was fine and involved redistributing patch cables around to where they would suit best (length wise). I've gathered so many patch cables over the last several years that this wasn't a problem. Anyway, all seemed well.

I've been having troubles streaming/transferring content to my notebook, so last evening I started to investigate. I quickly noticed that both the family desktop, and my desktop PC's were both only connecting at 100Mbps. This of course made me start to worry.

After doing all sorts of different tests and trying out different things, I finally found my reason.

Needless to say, I was not impressed. I don't know HOW I managed to give the main two PC's to connect at Gigabit speeds the only two patch cables incapable of reaching those speeds!


So the lesson here is of course is if you have network problems, CHECK YOUR CABLES!! (especially ISP/Router supplied ones).

1308004 2012-10-22 00:36:00 what's wrong with it? I've got one that came with my xbox, it's only got two wires in it that I'm pretty sure handles 100 mbps, all the rest of mine are fully loaded. Do you need all 8 for gigabit? 8ftmetalhaed (14526)

Yes.

1308006 2012-10-22 02:12:00 If cable runs are reasonably straight, and holes in studs, dwangs etc are reasonably large, can you use the old sparkies trick of using the cat5 to pull a better cable through? Richard (739)

Probably, although I'm no expert.

Not needed in this case however. We have Cat 6 for the structured cabling part.


Problem was with the patch panel from the PC to the wall.

1308008 2012-10-22 03:28:00 Yeah, the telecom routers are provided with poor cables that only have the 2x pairs. The cable I got with my dynalink (which I never used, instead it was cut up) didn't have solid core cables. Instead they were made with stranded copper. Dunno how that affects performance, can't be good though! The Error Guy (14052)
1308009 2012-10-22 04:11:00 We've never bought any network cables. Got them with the modem/router and one was from our US Robotics PCMCIA 33k modem + 10 (?) network card. They all work at 1Gigabit speed as a "crossover". Nomad (952)
1308010 2012-10-22 05:25:00 Why buy cables or patch leads, they are cheaper to make yourself, easy to make and at least you get the exact lengths you want.

Cant remember the last time I ever brought a pre-made cable. Brought plenty of 300Mtr rolls :D

Stranded is what's used for most patch leads. If you use solid, the wires break after bending a few times. Solid cable's only meant for permanent wiring.
