I'm evaluating our first WR11XT but can't get the remote SMS administration to work reliably.
We have 35+ WR41 and WR21 and never seen this issue.
Sometimes the router receives and executes the command and sometimes it seems the text never reaches the router.
Nothing in the log.
Sometimes the text is delivered after a delay and sometimes it helps sending several commands in a row.
Network seems connected since I can send SMS from the routers command sendsms.
Same issue on both 220.127.116.11 and 18.104.22.168.
Someone else seeing this or have any ideas?
