Lately it seems to be disconnecting intermittently. Also I haven't been able to get any updates when I run filehippo app manager because of a communication failure error. It might be related. Lastly I was searching online about this problem and I decided to run MiniToolBox and I am not sure if I should post the report that was generated. TIA.
