Hello- I recently had a problem with a router, and found it to most likely be the hardware
Long story short, i copied the image from that router (dd /dev/mtdblock5 then mtd write) directly onto an identical router and the problems did not follow - which indcate hardware was most likely the problem. I recently was struggling with wifi stability issues on my wzr-hp-ag300h. Before a software update, it was pretty bad, then after upgrading to trunk it was mostly unusable. I updated to trunk because I knew a lot of driver advancement had been made, and was hoping it would help my wireless problems. After hours of troubleshooting, I started looking at wireshark, and saw a lot of [TCP ACKed unseen segment], [TCP Previous segment not captured], [TCP ACKed unseen segment], [TCP Dup ACK 61#1] and [TCP Out-Of-Order] that would imply large amounts of packet loss. A check with MTR indicated icmp loss to a machine on my local wired network, the loss coming and going but averaging 20-35% over 160 pings or so. This occured on both 2.4 and 5.2 GHz. On this device, I believe they are physically different chips. No usual logs showed up in dmesg or syslog. I don't remember the interface statistics showing anything that seemed wonky (unusual number of errors/packets marked as dropped/etc). I'd like to learn more how to look into what may be causing this issue. Is there any kind of additional debugging people can recommend? thank you Camden
