Hi

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. If that did not work then you might have to recreate the SSID for your wireless network and then go to subsection security and select WPA2-PSK or simple WPA-PSK then enter your desired network key.Change the channel number as listed above. Once done with all these things then click apply and reboot if prompted.
Good Luck.
