Ac1350/Archer c59 as a Repeater dropping connection.
Hello, I'm currently helping a friend set up a network in his garage, and we're using an Archer C59/AC1350 as a repeater/extender. The main router is also an Archer C59. Everything works for the most part, but every once in awhile the Xbox the is wired to the main router loses connection and the only l way to fix it is to restart the main router. Wireless connections seem to fine for the most part, but sometimes phones lose connections for a second or two. Disconnecting the second router in the garage seems to fix the issue. Any solutions would be appreciated.
Some basic info
The router connected to the modem is now named Router #1 and the one in the garage will be named Router#2. Router #2 has it's 2.4Ghz disabled to just to reduce clutter and is connected to Router#1 via 5Ghz. There a Pc connected to Router #2 via ethernet that seems to be fine and stable. Thanks for any help or information, it's appreciated.
