Configure the router

Registry adjustment

Actually, this is not all. In some cases, the error 651 can occur again and again, and even all the methods described above do not have any effect on the situation. In this case, it is necessary to take drastic measures.

This is due to editing the registry. Inexperienced users should be advised not to do such things on their own, or the whole system can fail.

Now you need to rename it to “Enable RSS” and set the value to “0”.

In the same way, another “DWORD (32 bits)” parameter is created, after which it is renamed to “DisableTaskOffload” with the subsequent assignment of the value “1”. Now it remains only to restart the computer system and wait for the changes to be made. In theory, the problem should disappear.

Conclusion

As can be seen from the above, the error 651 itself or the notification of it is not very scary, and you should not panic ahead of time. Of course, here are the main ways to correct this error,But who said that this problem is connected with the user's system?
