You will need to check the following....
1. Check Hosts file (C:\windows\system32\drivers\etc\)
2. Check TCP/IP Settings on the Connection and make sure they are Acquire and not set (Static).
3. Just for giggles.... Open CMD as Admin (Click Start, type cmd, hit CTRL+SHIFT+Enter)
type ipconfig /flushdns and then enter
type ipconfig /registerdns and then enter
The IP of 127.0.0.1 is the standard LocalHost Loop Back address.
This is not used for anything other than looping back on itself.
Definition: The
IP address 127.0.0.1 is a special purpose address reserved for use on each computer. 127.0.0.1 is conventionally a computer's
loopback address. Network software and utilities can use 127.0.0.1 to access a local computer's TCP/IP network resources. Messages sent to loopback IP addresses like 127.0.0.1 do not reach outside to the
local area network (LAN) but instead are automatically re-routed by the computer's own
network adapter back to the receiving end of the TCP/IP stack.
Typically all IP addresses in the range 127.0.0.1 - 127.255.255.255 are reserved for private use, but 127.0.0.1 is by convention the loopback address in almost all cases.
Typically, If you are getting that, then something/someone and/or Virus/Malware/application set this IP.
You will not just get this IP appear for no reason. It's not an accident, and it isn't normal.
If the system could not pull an IP from DHCP of the Router, then you would NOT get 127.0.0.1
you would get something like 169.254.???.??? which is known as
Automatic Private IP Address (a.k.a APIPA)
And is assigned by Windows when an IP Address can not be found from DHCP or other.
You can also try reisntalling the Network Drivers, but if something is forcing it on the Network Adapter, then you could have a bigger issue. "something/someone and/or Virus/Malware/application set this IP."
I would start checking with Malwarebytes and On-Line Virus Scanners.
NOD32 and
Windows Live Safety Scanner
And get rid of AVG if that is what you are using.
Might want to uninstall any Internet Security Suites if you have them installed.
AVG is garbage, plain and simple
as are (imo) All Internet Security Suites
This will not be easy to track down necessarily.
Recommendation: Microsoft Security Essentials or NOD32 or maybe Avast (MSE over avast though).
Malwarebytes and Spybot S&D.
The hosts should look like this,,,,,
Code:
# 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
This is the standard Default Windows Hosts file.
There is no extension, just open in Notepad.
If there is anything else in there, CTRL+A to select all and delete it, then
Just copy and paste this into it and save it.
If it is set as read only, you will need to change that by Right Click and Properties on the Hosts file, then try it. Then set back to Read Only.
