Thanks Jim and David, I will not have time to try these suggestions until tomorrow night.
Jim, no, not on same switch as local lan. David, have been debating whether to change RTL8139 to some form of 10/100/1000 card. Prefer to solve problem I am having first. And. maybe, (by your suggestion) swapping nic card "jobs" will solve my problem.
