So this may be a little irrelevant to openwrt..well idk but I made a thread similar to this a while ago and thought I was done with it, but I guess not. So before I did talk about how I was receiving rx dropped packets on my eth0 interface that hosted my gaming pc and increased buffer sizes which I thought it helped. Well I used eth2 for my gaming pc and the buffer sizes are pre set to max but from the jump I see that I am still experiencing packet drops. I checked stats on my pc using netstat and it shows that I am getting udp errors despite opening udp ports my game uses. I simply don’t know if this is at the router level or pc level as majority of it should be tied to the router no? I just don’t know why my pc is getting packet loss. For more context I even switched my access point to eth0 and it didn’t get any dropped packets. Before my pc used to be connected to that and it was dropping packets. It just leads me to believe it’s my pc but then again it could be at the router level. Any trouble shooting advice or solutions?
Packet captures with things like tcpdump or wireshark? tcpdump can be ran on the OpenWrt device.
Dropped packets with TCP are just part of most congestion control algorithms and not necessarily a problem. Are you experiencing any problems or is it just the statistics scaring you?
For example, my VDSL modem shows billions of Reed-Solomon Error Corrections each week, but zero CRC or Header errors, so there's no real problem, just error correction working as it should (I think...).
It’s the stats. Cause on eth0 there’s no rx dropped. There used to be when my PC was connected to it but now that I have my pc connected to eth2 so I can utilize 28125-rss driver, I still see rx dropped. That’s leading me to believe that it’s my pc even tho I have ports open for the programs I use.
