Oh spit

Well,got home,deleted the home network (linksys) through Manage Wireless Networks,rebooted,and reconnected under available networks,and I'm still pulling a 127 IP.Guess I'm not deleting the network profile with this method? Also,after reconnecting,I didn't get the window with the three choices-Home,Work,or Public.Going to need some further assistance...

home should be sufficient for your purposes.
However someone has been kind enough to put up a post on this
Network Location - Set as Home, Work, or Public Network

Understood-

and I'm aware of the proper selection,but that option is not appearing after reconnecting to the (linksys) home network.This would seem to tell me that my comp recognizes this connection and assigns it a "home" designation without asking my input.It's being shown as a home network in the network share center.

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.

Quote:
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.

well that's scary

Agreed with AVG-I run Spyware Dr. w/Antivirus-scan weekly with MBAM,SAS,ESET online,A Squared,and occasionally fire up AdAware-tracking cookies are all I find.I'm super careful when surfing and security is probably the only real knowledge that I have when it comes to software.Tried the resolver cache clear,ipconfig release/renew-haven't tried a winsock repair yet.The only place that 127 IP shows up is on the network map.If I dig into properties for my wireless,I find a 192.168 address.My other comps show this one (the Lenovo)as having a 192.168 address in the network map.I'm just beat tonight and don't have the energy or desire to chase this around now.Many thanks for your suggestions and info on the 127 IP-perhaps tomorrow night if you're available?

anh,not really, A GeekSquade Favorit fix all, that only resolves the simplest of issues. I personally don't recommend it.

Please explain in detail what you mean by that.
Is it set Static?

is your network Static IP's or DHCP?

Just a couple guesses,.,,,,


Then 127.0.0.1 may not be of any concern.
When you go to Command Prompt and run IPConfig, what IP are you getting?

Also, run the ipconfig /flushdns and ipconfig /registerdns on all of your systems.


As a side note,, I have seen the Master Browser cause issues......
Also, keep in mind the following....

One PC always has to be the Master Browser
In a Workgroup Environment, the Master Browser can change from one PC to another.
There can be some issues and/or conflicts with this....

One way to try and fix this is,,, turn off all PC's
Then turn only one on and let it sit for about an hour, logged into Desktop, make sure it can get out to internet and all. (Yes, 15min says MS, but that is not always the case)
Then power the rest on, one at a time about 20 min apart.

I always make my internal ips static. It makes things a lot easier, that way you can scribble it on a 3x5 or something for reference if something ever becomes stubborn you know it's internal ip address. For pinging, finding etc...

thanks for staying with me

Well by digging,here's where I went-Wirless Adapter>Connection Status>Details-here is where I found a 192.168 IP(v4) and subnet mask info 255.255.255.0 and default gateway 192.168.2.1-all normal from my limited experience.Then I went to Network Connection Properties.double click ipv4 and radio buttons are checked for obtain IP auto,and obtain DNS auto-so I guess I'm not "static",correct? But wait,there's more! A command prompt of ipconfig or ipconfig /all does not yield any relevant ip info-just a string of media disconnected entries-now that's a problem I've had for some time,even when I could "see" the XP's on the network.For sake of comparison,I fired up a Compaq running Win7,and on the network map,it too,saw itself at the 127 IP,but saw the Lenovo with a 192.168 IP-Also the Lenovo sees the Compaq at a 192.168 IP. So to recap,they both "see" themselves as this rouge 127 IP,but "see" each other with their correct 192.168 IP's Are you with me? The big difference is that the Compaq "sees" both of the XP's on the network,where the Lenovo does not-which is my original problem as started in this thread.So maybe chasing this 127 IP issue is not where the problem lies.I would be happy to first get a proper list of info from the Lenovo when I run the ipconfig command and maybe go from there-make sense to anyone? Please bear with me-as I stated earlier,networking is well beyond my area of expertise.Thanks again to you all for your help and suggestions thus far. Also,now at work,and a co-worker's comp sees the Lenovo on the network with a 192.168 IP,and it sees itself still as a 127 IP-Go figure
