Yea, it bothers me in the way IT stuff that doesn’t work right bothers me. It should work, but I have a painless workaround. I’m learning to get over that kind of thing 
I’ll live with it. To many mac reservations, etc to factory reset unless something REALLY BAD screws up.
This is one thing I love about pfSense. You can pull a time stamped backup of your router config prior to making change and save it to any computer. Luckily I haven’t screwed up my config yet so I haven’t needed to use. it.
I can do a backup. But if it’s something in your config and it’s in your config backups, then when you do a factory reset and restore the backup, you just restored the problem…
Its more of keeping a known working version. Then making changes. If you hose something up you can revert to an older backup.
The backup files are tiny so I keep a ton of them.
Me too, but when did this problem creep in? Is it config related, or just a stuck bit somewhere… I know what you are saying though, and I do make regular backups of my config when I am changing something. But I hate not knowing what the problem is before I do a factory reset… A reboot normally clears the stuck bit so it leads me to believe it’s something in the config and I have no idea when, how or where the config was impacted… So as long as it’s working for everything else I try, and just giving me problems on my PI’s, I’ll assign static addresses and live with it. If it gets worse, I’ll take more drastic measures.
Something I ran into tonight, not sure if its an issue for you.
I had the wifi setup for my pi. Moved to a location with a wired connection and plugged it in. It was grabbing both connections. if you run ifconfig do you have a wlan and eth0 connection? if so do they have different IPs? Can you block one of them from functioning and see if that helps your issue?
This only applies to a Pi3 but I remembered you having this issue and figured I would throw out an option.
Yes, I’ve experienced that before too. All of my Pi’s are wired. I have a 24 port switch sitting right next to them :). I do not enable wireless on them for that very reason. Seems like the one time I enabled it, I had a hell of a time disabling it. But thanks for thinking about it.
