Ethernet doesn't work on one day of the week

[North56789]

So I have been having these very strange problems for the past 2 months. My Ethernet works fine 6/7 days of the week and on usually Sunday's it doesn't work and goes to limited. I try to get help but the next day it's working fine! I don't get why it only doesn't work one day of the week. I have Comcast, and a net gear router. (Btw my wifi works). Also I have tried to use Windows troubleshooting and it says 2 errors. 1. I don't have a valid IP address and 2. Default gateway is not available. I have fixed the errors and what happens is my internet works for about 1 min and then goes back to limited and says the same 2 errors or both of them but separately.

Do you notice this on only one computer, or does any PC wired to your router drop to limited on Sundays (or whenever it drops)?
