Hi Stephen,

I'm not 100% sure, but the way you connect the wires to the connector may have an effect on speed (see below). Length may be another thing to consider. Make sure that all cables are at least 1.5mt long (I think 1mt will work, but am not positive).

Here's an excerpt from a cabling faq to help you with the wiring.

Good luck!

The EIA/TIA specifies an RJ-45 (ISO 8877) connector for Unshielded Twisted Pair (UTP) cable.  The plug is the male component crimped on the end of the cable while the jack is the female component in a wall plate or patch panel, etc.  Here is the pin numbering to answer the question, where is pin one?
