Atheros RX errors are gone
I just installed last snapshot of 1.2.3 (pfSense-Full-Update-1.2.3-20090130-1630.tgz) and Atheros RX errors are gone. I'm using D-Link DWL-G520 PCI card with AR5002G chipset. After 3 hours uptime I have only 163/0 (In/out errors).
Did you change any settings and did you do an update or an clean install?
For me its:
Packets in: 97714
Errors in: 4163
Atheros also (5212 or 5213 as far as i know)
Just update, without changing any settings. This was my second update to 1.2.3:
1.2.1 -> 1.2.3 (20090125-0939) -> 1.2.3 (20090130-1630)
Btw. I think your numbers are good. With previous snapshot i get 10x more errors than packets. Interesting thing is that more errors come when the communication was idle…
