yes that is no worries at all to have to figure out and get setup for a return.
ok so when i setup the router i had put isp ONT in full bridge and restarted it let it fully boot up, then i turned the r3 on and let it boot up, logged in and it said i was only getting around 800 upload and around 850 download.
then i went to look at the bufferbloat with those speeds and they were all over the place so i had configured the congestion control however i have to drop everything down to about %60 of what i pay for which i just dont think is right with fiber.
yes i run on dhcp as well!
