Hey Dogie,
I do not know how to change my subnet on my router. I tried plugging in my ethernet cable from the WR to my desktop. In Ubuntu, I opened Network Connections. I double-clicked auto ethernet. I clicked the Ipv4 settings tab. For the method, I chose manual. I added an "ip address of 192.168.1.2, a netmask of 255.255.255.0, and gateway of 192.168.1.2. I clicked on Require IPV4 addressing for this connection to complete, and then hit save. I tried to go to 192.168.1.201 WR address in google chrome and firefox and could not connect. I tried it by not requiring IPV4 addressing for this connection to complete. I tried it after rebooting my computer. I tried it by reconnecting the ethernet cable to my router. I do not understand how the ip address, subnet, and gatway addresses work. Thanks for trying to help tho.
Sincerely,
Seminer
Gateway to the thing you're trying to connect to, ie 192.168.1.201 - that should do it.
