Solution 2: Ten Second Power Off

Quite often, hang-ups can be caused by internal or firmware problems. It is generally a good idea to plug everything out once a week for 10 seconds to avoid problems

Make sure to actually count the seconds. If you just plug out your modem and other DC adapters but don’t wait long enough it won’t have any effect.

Solution 3: Update Realtek Drivers

Realtek drivers are known to cause problems if you use an old driver or your modem does not support a new drivers and requires an older driver. Both cases are possible, so you should try the newest driver first and then lookup the manufacturing date of your network card to see what driver is required

All drivers can be downloaded from http://www.realtek.com.tw/
