Having two HP printers which were shared on windows computers.
Printers are going offline specifically after adding two Access Points on the network.Sometimes when I disconnect the wifi and then connect then the printers are becoming online and sometimes when I restart the printer spooler then its becoming online.
Mostly all recent issues are related to wireless devices.
Having some issue with DNS also ,I mean sometimes I cannot ping to computers with their name but sometimes I can. So may be because of the printers shared with computer names and cannot be resolve.(this DNS issue started after adding new APs).
Cannot ping wireless devices each other on new APs.
Windows updates were not enabled in most of pc's ,may be by enabling it resolves to some extent.
Cannot conclude whether the issue with network,printer drivers ,printers ,computers or...
