For these past few weeks, my 'HP: TS 14 Notebook PC' has been giving me trouble. I turn it on and it does not connect to wifi as it had done before. I go into 'control panel' to try to turn the wifi on manually but there are no wifi settings. It has windows 8.1 so I go into 'PC Settings' and into 'network' but there is nothing concerning wifi either. I went into the 'HP Support Assistant' and there was an update for the wifi adapter. I tried to update it via Ethernet and it downloaded but it did not install. I would like some advice on how to rectify the problem.
