2. Thay đổi DNS sang Google DNS hoặc Open DNS (như bác trên chỉ đó)
Đồng thời phải chép thêm vài dòng vào file hosts ở đây C:\WINDOWS\system32\drivers\etc.
sau khi sửa xong, nội dung file host phải thế này:
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
