Install latest ZD firmware, 9.12.3.0.34 for latest fixes and enhancements.

Try reducing DHCP lease time on the ZD to minimum 6 hours.  Limited network implies Internet access, not 
necessarily a problem with wireless local network access.  Check your WAN interface statitistics with your ISP.

Not sure how you could be not seeing your SSIDs, but 7341 is 2.4GHz band only, and might encounter RF interference
that can affect client experience.  Do all clients have problems in certain areas?
