it is a good idea to review the most current copy of Part 97. The ARRL book is excellent for that.
As for using the WiFi router for Repeater control, you would have to lock it down very well, use special firmware, or some non-ham script kiddie will attempt a DoS attack (denial of service). You can try all you want but you will be locked out unless you have a smart way to ignore a data attack. Most operators hang two receivers on the input and a few minority even use the output frequency. You just have to know how to do it. Adam kb2jpd
