For quite some time, my desktop has had trouble loading browser tabs, videos, etc., plus occasionally some gaming challenges. Turns out it may be a Double NAT issue, possibly with originally having a weak DNS server (since updated).

Curious if folks can help me troubleshoot my setup to resolve the Double NAT issue

Modem = Spectrum EN2251 >> Router 1 = Google WiFi router (using 1 from a 3-pack, pre-2020) >> TP-link ethernet port >> Router 2 = Fios G1100 (pre-2020)

From what I can tell:

• Modem doesn't have a proper bridge mode / is already in it
• Tried adjusting Router 1 from NAT to bridge mode, but it doesn't save
• Tried adjusting Router 2's Network (Home / Office) by making the IP address 1 above Router 1's, and then changing DHCP to no IP, but it just kills internet on Router 2 (for which I then factory reset things)

Minor notes:

• My personal desktop and work laptop are connected via ethernet to the ethernet port
  • Used to only have wifi to Router 1 and tabs would be slow to load
• Roommate's computer and my PS5 are connected via ethernet to Router 2 (and don't seem to have major connection issues)
• Speeds are good, just quality is off

Guessing it's having the right settings on Router 2, but unsure what to do... Tried chatting with Google live support to adjust Router 1, but no major luck.
