Re: QNX 7 E1000 Driver Very Slow Sending Only
Good news! Glad it is working for you.
Nicinfo only displays hardware errors, so you need to run netstat to see TCP/UDP problems.

The computers are all located in a lab with no outside access (closed network) so there is very little traffic.
I swapped Ethernet cables on the chance it might have been a bad cable I used but that made no difference. I was *
this* close to writing back when I decided to switch ports on the Netgear router. I hadn't done that prior because I had
plugged into a port that was being used by another computer in our lab so I *knew* it was good.
Of course the instant I plugged into another port everything started working in both directions. So the port must
have been degraded after all and just no one has noticed because they haven't transferred any large amount of data in
the bad direction on the prior machine that was plugged in there!
One final question though. I swore prior versions of QNX showed these types of hardware issues in Nicinfo which was
the first place I went when I was having problems. The fact there were no errors reported there made me think it was a
configuration issue vs a hardware one.
Thanks for all your help,
Tim
