@crispyoz Thanks for your thoughts

I have received 2 Omega Dash and they both exhibit the same problems.
They are dynamically assigned IP addresses from a Verizon G100 router with a lease time of 17 minutes(1020 seconds) over wifi
from a network named "disabled" (really!) which uses Internet Systems Consortium DHCP Server 4.3.6.
Everything is OK for hours at a time.
Frequently
connectity is lost for anywhere from a few minutes to an hour.
During this time the blue LED blinks.

I have not yet begun to develop my display applcation.
The only things I have running are cron jobs to display uptime, IP addresses from ifconfig to /dev/tty and
save the log to /mnt/mmcblk0p1/log

The log entries (315 lines ) are at https://Real-World-Systems.com/omega/wifi_dies.log

++Any suggestions to resolve or diagnose this problem would be appreciated.

@Yvan-Gagnon If your Omega can be accessed via IP address (like a dynamic one assigned by your internet Service Provider) and you just want a static name you can try http://changeip.com/dns.php for their Dynamic DNS. Some routers support them and can notify them when your IP address changes.

Just upgrade to
Ω-ware: 0.2.2 b200
uname -a
Linux Omega-98F5 4.4.74 #0 Tue Jul 31 16:32:08 2018 mips GNU/Linux

SOLVED! @György-Farkas Thank you VERY much.
The fifth(5th) line being:
##src/gz reboot_packages http://downloads.lede-project.org/releases/17.01-SNAPSHOT/packages/mipsel_24kc/packages

Why is that line in distfeeds commented out?
What about the next lines?
+++++++++++++++++
I have BusyBox v1.25.1 () even though I tried to get most recent packages. Should I replace 1.25.1 with 1.31.9?
What did I do wrong?

diff
-ash: diff: not found

find / -name diff
+++ returns nothing +++

Does not seem to be in BusyBox v1.25.1 nor as a opkg module

any suggestions would be appreciated.

@Douglas-Kryder Thank you VERY much.
How do you know that?
I've looked at opkg list a dozen times trying to find it.

I must be thick. I am trying to find and install a utility like diff but I cannot figure out what pkg it is in.

After opkg update
/etc/opkg/distfeeds.conf includes:

http://downloads.lede-project.org/releases/17.01-SNAPSHOT/packages/mipsel_24kc/onion/Packages.gz

But there are NOT onion directories under mipsel_24kc

@Christian-Munk
In general, first thing I always recommend is changing
/usr/bin/radio.sh & > /dev/null
to
/usr/bin/radio.sh & > /var/log.radio.log
Why would you throw away whatever the author of a script was trying to tell you.

The technique to solve this and many problems in general is:

1. copy the origin source to source.broken (or similar)
2. remove a chunk of code, especially on of a group of similar segments.
3. Try it.
4. Save that version and go back to step 2 if it still fails.

I have found that having 2 windows open, one with vi chopping up the code and another executing the code allows you to undo the last delete +and examine it carefully.

Another thing that you can do, when if executes but not the way you want is the oldest(well second oldest after setting an address stop +from the front panel) add output statements like
echo "got to stage2" >> script.log
or
logger "stepping along count:$count:" #this goes to either the local syslog hopefully configured to save messages in /var/log or even +another system that can collect the messages if the target system cannot be accessed now (or later)

Get rid of most (not all ) of the if..fi . This won't fix the problem but will allow you to get a better view of what remains.
