It's dual band with 2.4 and 5 GHz signals, two WiFi options. Also noticed people having problem with connectivity like Google play store, YouTube... I suggest them to go to ACCESS CONTROL option and edit the blacklist and whitelist as required, I was having the same issue, I took ME days to notice. Switch off the WEB ACCESS LIMIT or type in a site which YOU don't access at all in the blacklist, also check the time set for the WiFi. It will help.
