I have the newest comcast router with the 10.0.0.1 range of ip if that makes a difference
I doubt it. I have been using the same Comcast router for a few years now. I blame most of my connection issues with the company (and also on who creates the room/team leader), though that's another conversation entirely...
After checking my router to find my dhcp ranges i set manual ip settings as followed
Ip address - 10.0.0.254 (just outside the range by 1)
Subnet mask - 255.255.255.0
Default gateway - 10.0.0.1 (ipv4 gateway address)
Primary dns - 184.108.40.206 (sylverant)
Secondary dns - blank
The only time I have had to set this manually as such is when tunneling via crossover cable to pc after bridging LAN and Ethernet for a connection. I have done this in the past to connect to other servers using a PLUS disc when that was the only version I owned. However, I used 10.0.0.3 for GC IP and 10.0.0.2 for both Gateway and Primary DNS because the actual DNS is connected via a program such as Mr DNS/Dr DNS. I am not cogent enough to understand whether or not this matters, but it was my first instance using the method I arrived upon which actually worked so I kept it. It still works when I (infrequently) wish to use it.
Apologies if my input is unwarranted or off-base. I have a very nebulous understanding of networking in general. Anyway, it is strange that you cannot just auto DHCP with that router.
