This was a huge help actually. After you brought this up, I remembered seeing a setting for it within Unraid's network settings. Also before changing anything I checked the IPs of the devices that were working and they were all under .126. I found the setting in Unraid again and changed it. See in the screenshot, I changed it from /25 to /24 and now all the other devices work as well, which have IPs above .126.
Interesting. And yeah other routers I have used were either 192.168.0.1 or 192.168.1.1 but my current Asus router and the Asus router before this were 192.168.50.1 by default.
Thank you both @itimpi and @Frank1940 for your time and assistance.
