My hp/g62 is fine conecting to the wifi, but browser (chrome or Explorer - the same story) is only sometimes richable. It is alike I can see one website every 60 min. browser says: the website is unavaiable, connect later, and down on it: dns is not responding. Other time: connect error: time out etc
You should check you browsers security settings to make sure that they are not set too high and also the routers security settings. If these settings are set too strick then it can slow down and even deny access to web sites. Also the security certificates option needs to be set lower.
