Acceptable # of TCP Checksum errors
I've been wondering for a while if one of my PCs has a low-quality NIC. So for the first time in a long time I looked at the stats on my NIC and saw 600-ish TCP Checksum errors since the last reboot. Mind you this is with 40 million packets (TX + RX) and 2 GB of data (and it's a mix of LAN and Shaw traffic) so I would be shocked if there were not some Checksum errors.
The question is, in general, what's a normal number of these errors (expressed as a percentage of total packets or bytes)?
Zero to thousands. I really wouldn't worry about 600.
To isolate that it is the NIC, you'd want lower level ethernet stats. TCP is layer 4 on the OSI model, so those errors could be occurring anywhere in the data path on the internet. Layer 2 stats will tell you about your local network.

Realtek? Atansic? SiS? VIA? All of those are considered to be low end NIC's that can be susceptible to errors.
