Thank you for looking over the config. I was able to find the issue and it was not the router. I did have problems setting my router to the IP I was using before (25.50.75.100), so I used 25.50.75.1 and forgot to change the gateway setting in my server. I use that IP range only because I like the number progression. I have used it for years now without issue. I know that there is a lot I have to learn about networking. If you don't mind, can you explain what are the problems with using this range on my LAN? Or perhaps point me to a resource?
Thank you so much for all your help so far. I am very happy with my Ubiquiti setup, and will be adding another AP to it in the near future.
