A few issues here:

First, in my experience as System/Network Administrator, I'd have to say that
approximately 20% of all 10baseT ethernet cable ends are duds. That includes
both those bought commercially as well as those hand-crimped by me and my
colleagues. It is well worth your time and energy to buy one of those ~$75
cable testers. And a _quality_ crimper saves on curses as well!

Next, you may want to check out http://www.faqs.org/faqs/LANs/cabling-faq/ and
http://www.faqs.org/faqs/LANs/ethernet-faq/ and our own
http://www.syrlug.org/docs/howtos/Ethernet-HOWTO/index.html for Ethernet and
Cabling details.

Finally, I've never heard of, nor read of, nor experienced a mis-wired cable
causing damage to hardware. However, I can imagine how if you were to not
fully crimp the ends, the little metal tabs on the plug could stick out far
enough to physically damage the pins in the jack. For that matter, I once
knew Network Admin who had the habit jamming plugs upside down into jacks,
thus damaging several. This fact, combined with your mention of having to
force the plug into the jack leads me to believe that this or a faulty
crimping may be your problem. If so, you'll probably have to buy a new
network dongle, and you can kiss at least one port on your hub goodbye.
