Running AC68U with only 2.4 GHz radio on. Previously our computers and printer could remain connected to this router indefinitely. Now, although there's no problem connecting with a laptop, the connection becomes useless (radio on; still secured; no Internet) after only a few minutes. A working connection is easily re-established by disconnecting/reconnecting the wireless on computer, but this becomes frustrating very quickly.
Same behaviour on two different Windows 10 computers. No changes have been made recently to settings or firmware, but of course both computers have had automatic updates.
Only one deviation from recommended settings is that we have to run router as Wireless Mode = Legacy because the printer is not mode N.
Grateful for any suggestions to troubleshoot and/or fix! -- JCW3
