>>> This happened again today. I was able to do some experiments this time
>>> so I have new data.
>>> I ran the HDHomerun_Config gui and both HDHomerun devices were missing.
>>> I power cycled the HDHomerun units and no difference. I also ran
>>> <hdhomerun_config 10137DC1 set /ir/target "192.168.1.111:5000
>>> no_clear"> before and after power cycling the HDHomerun units and linux
>>> just gave an error message <unable to connect to device>. This is the
>>> command I use in rc.local to configure the units on power up. Power cycling
>>> the mythbox without power cycling of the HDHomerun boxes fixed the issue.
>>> I noticed this evening because the remote would not work (the HDHomerun
>>> has the ir reader). We went ahead and watched our evening show without
>>> issue using a keyboard for control. Then I ran my tests after we were done
>>> I also noticed that our 3PM show did not record but the 8AM show did
>>> record. The 3PM show comes on again at 6PM and myth tried to record it both
>>> times but failed.
>>> This sure looks like something new to Mythbuntu 16.04.1 LTS. I ran the
>>> same hardware with Mythbuntu 8 for ten years without this happening. It
>>> seems to happen not quite once a month and the unit is on 24/7.
>>> Any ideas? I don't know what to do.
>> This is an update. I think the consensus is that this is a network
>> problem. I got the suggestion from Silicondust that I see if the HDHomeRun
>> units are visible from my Windows computer on the same network. I also set
>> the IP addresses as reserved in case it is a router problem although that
>> seems very unlikely. At this point I am going to wait and see if it happens
>> again and them do some troubleshooting.
>> I guess there is a legitimate question if the drivers on Mythbuntu 16
>> could be incompatible with my old motherboard. I never had this problem
>> with Mythbuntu 8 which I ran on the same hardware for many years. Something
>> like this happened on my video card drivers causing many hours of
>> troubleshooting and way more learning about video drivers than I expected
>> to need.
>> Should be using a different network driver?
>> Here is some information from lspci -v

This from syslog:
*Apr 2 13:07:36 NewMyth avahi-daemon: Withdrawing address record for
192.168.1.111 on enp2s0.*
And this bug without solution
Not sure what to do.
