Fix 4: Reset or Restart Your Router

If none of the solutions have worked for you and you have just confirmed that there is not a server issue. Then there might be a chance that you are facing a TCP / IP inconsistency.

The issue is quite frequent with low-level routers that can only handle limited bandwidth. However, the issue occurs in instances where various devices are connected to the same network while you are attempting to stream content from Hulu.

In this situation, you have different options available:

  • Restarting your router
  • Resetting your router

Restarting is a non-intrusive method but will only fix superficial instances where the issue is related to temporarily saved data. If the issue occurred after a setting or limiting imposed at a router level, then try to reset it.

Restart Your Router

A quick reboot will let you wipe some connectivity problems that you might be dealing with. This is enough if the issue is related to a TCP/ IP.

If you want to perform a router restart, check the back of your router and hit the On-Off button to cut off power. After this, try to unplug the power supply from the power outlet and wait for a while in order to drain the power capacitors and release any temporary data that your router might be holding.

When the period is passed, simply restore power to your router and hit the power button again to again start it. Then wait for Internet access to be restored.

If you know the consequences and still want to reset every router settings to their factory state. Then move ahead and locate the reset button on your router back. In some situations, it’ll be built inside the case to protect accidental presses, so you want a small screwdriver or the same object to reach it.

If you want to start a router reset, hit and hold on to the reset button. Then wait for a few seconds or until you view every LED flashing at the same time.
