Just had FiOS installed. After the install my speeds were 25 down/5 up. I ordered 20d-20u, so they had me run the optimizer and my speeds went to 25d-20u, which I liked. However, I need to change the DHCP scope as I usually run into issues connecting to other networks via VPN for my company on 192.168.1.XXX, so I changed back to the original IP scheme I had before the install (so I could see my printers, NAS and home server).
Speed dropped to 15d-5u now. Ran the optimizer again, but no change. The only issue I ran into during the changing of the DHCP range was that I didn't know what to enter for DNS, so I went with 4.2.2.1 and 4.4.8.8
Do I need to change the DNS to someplace else? What should I be point to?
Thanks
