t seems like a WiFi channel conflict so all you need to do it to change your WiFi broadcasting channel. Open up your router`s setup by entering the default gateway IP, enter username password if prompted ->go to WiFi or Wireless Lan setting and make sure that broadcasting is b/g/n mixed mode, then check what broadcasting channel is selected starting from 1 to 11/13, in case of extreme start or end make in middle like 6 or 7 and in case of any middle number like 6 to 8 make it either 10 or 3. By changing the broadcasting channel shall hopefully stop any interference with other frequencies. for more help and support visit [http://goo.gl/fDYCSm|www.acer.com/wireless.help] and i hope this will help thanks
