Whenever I try to update an MMO (Like The Exiled Realm of Arborea (TERA), Ghost Recon Online and others) or on very rare occasions when I download some update or file from the browser, my wifi connection just drops and then restarts some thirty or more seconds later. Please, help me out with this. What may be the cause of this randomness and how can I remove the problem? This problem has only occurred relatively recently. Could it be because there are three or, on rarer occasions, four computers connected to the wifi network (all being within the same house)?
