电脑不能上网了，host应该怎么恢复

查找host文件
C:\WINDOWS\system32\drivers\etc\hosts
用记事本打开host文件 复制黏贴以下内容

# 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

保存

你把这个host文件用文本文档打开后，把里面所有的东西清空保存，就重启就可以了。
