Recently my internet has been dying 3-4 times a day.
ISP said that when it stops, it doesn't report an IP to them anymore, and a renewal doesn't work, I need to recycle the power on the modem then internet works and I can renew if needed.

The last thing I remember doing is a dist-upgrade with apt-get

The last thing wrong with the ISP was a connectivity issue which they "say" they fixed.. and it wasn't even in my area.

I'm just wondering if you guys think it's the ISP or if something in Redhat 8 is fumbling up my internet after an upgrade.

whats the lease duration on their IP addresses?

i just checked my dhcp leases file, looks like 7 days.

I also seem to have 2 entries for eth0
When I was on the phone with them I renewed my ip manually by releasing with dhclient and renewing - is that why I have 2 lease entries in dhclient?
