My Android NEXUS 9 is at issue 6.0.1, patched to March 2016. When browsing with Chrome, the connection to Wifi drops out and reconnects every few seconds. If I look at the wifi list of services, I can see my connection flipping between the service I want and my HP wireless laser printer. If I switch off the printer all the problems disappear . To avoid the problem I have switched my tablet to 5Ghz operation, as the printer only uses 2.4 GHz. What is the real way to fix this????
