We have a computer that is connected to a RUT241 via WiFi. We periodically check (every 5 minutes) if the connection to the router is working (by sending a ping to the router). This works great on many of our setups where we use the RUT240. We recently tested the RUT241 and it quite often doesn't respond to the ping (once an hour at least). What's weird is, that when the ping command returns with "Destination Host Unreachable", the response is coming from an IP address that we do not recognize (169.254.102.171). Even though the command "ip route show default" says that it's connected via wifi and the default route to the router is 192.168.123.1. Any ideas what could cause such issues?
