O.T.: How to make an idle connection persist

[Steve Holmes]

I found a similar situation with my wireless connection at home.  For
some reason, the connection would eventually quit working or even drop
off but if I use a ping loop similar to what you show below, my wireless
LAN would stay up flawlessly! Thanks for the suggestion of -i; I used a
shell script with a loop causing a single packet every two minutes like
this:
while true
ping -c1 <address>
sleep 2
done
Your idea looks to be simpler.
