Yea your right options are try it when router arrives, if no go, re-terminate to straight, if no go live with 100 meg.

In reply to a post by camieabz:

Assuming the CAT5 plugs are terminated properly, you can probably get gigabit* up to 100 mtrs.


Also good to get solid cable, as opposed to stranded.

I have doubts about the first point ...

From reading, the OP used Infrastructure cable, which is solid, into RJ45 plus which are designed for patch cable (stranded).

If both network cards are Gbit capable then I would suggest the problem could be a dodgy connection or two.

You and I both know that the cable which is probably solid should be terminated in IDCs on te back of an RJ45 socket mounted on a standard faceplate. Then patch leads from the socket to router or PC.

It is also (as you know) bad practice to install fixed cable in a non-standard way. They should be straight through and the cross over done in the flying/patch lead. How many times have I seen problems in wiring where something like that has been done.

My bad.

Well I tried computer to computer again, trying to force gigabit, one NIC just downshifted to 100mb the other wouldnt connect at all. Guess when router turns up will have to try both with short patch lead.

Well Apparently my wired crossover is to 10 Base T standard as found here. 100 Base T appears to be different as well as 1000 base t although the article in the OP suggests wiring is immaterial.

Well got the Billion. Connects at 100mbps so some wiring is required to standardise to straight through from crossed 10 base T. Just gotta wait for crimp tool to arrive.

Have ordered some sockets and back boxes to standardise the job. Anyone know which termination standard is used in UK, T568A or T568B?

Preference is 568B which is equivalent to 268A - but others may differ!

Blue and Brown are exactly the same but Green and Orange pairs are swapped.


But ultimately it does not matter, provided both ends are the same!

Ordered some from ebay 2 for 2 quid and free postage and fortunately they are Belkin branded and have colour codes for both wiring methods. Just waiting for back boxes now, damn post is slow.

And it works. Getting speeds of 400mbit which is probably the hard drive speed limit.
