pure unmitigated junk.

I agree with John's comment. Realtek chips are junk with unpredictable reliability, especially under heavy load. I have had several problems with various versions of the 81xx chips. When I tossed the cards in the garbage and switched to Intel-based NICs, all the problems went away.

Every time I build systems with Realtek network chips on the motherboard, I disable them in the BIOS and add Intel NICs instead.

YMMV, but please consider ditching Realtek altogether.
