So, I just bought a new lenovo ideapad k1.Net worked fine for a few days but then google and every other web page stopped working.wifi signal is good, I can download apps from the market without any problem but browser wont work. I tried resetting it to factory settings and it started working again but after a few days the problem started again. help? I cleaned cache, history, downloaded various signal boosting and network improvement apps, downloaded antivirus, removed all unnecessary applications, but only resetting it removes the problem and only temporarily. What can I do?
