That would be a great first check - eliminate everything you can.
Are you using a cable with all 4 pairs correctly wired {for 1Gb},
whereas only two pair {for 100Mb} ?
Are you using a switch ? If not the crossover has to crossover 4-pairs
correctly !
Is it a reasonable distance ? proper cat 6 cable ?

Thanks to Mr. Timms and one other gentleman for responding...
My problem was indeed due to using a very old cable. I don't have any
cat 6 cables, but I found that cat 5e cables work well enough for me.
In due time, I will likely eliminate my older cables and replace them
with cat 6. But, that is a project for a different day.
