I've had this AC750 wifi range extender for a while and it works really well I get really fast internet speeds. The thing is every like 30 minutes to an hour my internet cuts out for like 5-10 seconds and then comes back on. I've been dealing with this problem for a while now and I don't know how to fix it. Also it might be worth mentioning I have it plugged into my computer with an ethernet cable and i'm the only one who uses the connection.
