Windows 7: Unknown Router displaying on my Network

Sorry that I appear to have missed your reply here

The only thing I can think of that would cause the other router to be appearing in the your subnet is that the subnet is incorrectly defined (255.255.0.0 rather than 255.255.255.0) the only other thing I can suggest is if you try one of the other Private address ranges

This wikipedia page will give you the listings of those available for private networks ....

What does your network look like when viewed from the other machines?

Hi folks,

Any more news on this? I have the exact same problem. I think it is an unprotected network in my neighborhood I just don't know why it is offering it to me. :-(

I think it may be an unconfigured (not to be confused with simply unsecure) router within range that shows up when viewing the network. In my case, it occurs regardless of what wireless network I'm associated with and comes and goes as I go in and out of range of it (while staying fully connected to the originally intended access point). I think it might be part of Windows Protected Setup or something of that nature. It is grouped separately from my wireless network (and the computers attached to it) and is listed as "unidentified." Properties show its MAC address but no IP address.

Interestingly, it only shows up when I'm connected to an access point (doesn't matter which one). In addition, it also shows as an additional available unsecure wireless network in the list, but won't accept a connection.

Howdy Track7 and all others around here!

As far as I can see a year passed after the last post here.
Was any solution for this headache issue found since that time?

Pls prompt.

Thanx!

I have never found a solution to this. 1 year later, and I still occasionally see a router / access point that is NOT part of my network. I tried every suggestion offered in this thread (THANK YOU ALL), but nothing resolved the problem.

I researched this on other tech and networking forums, and discovered that many other people with wireless networks have a similar problem. I concluded that it is a bug, and probably (hopefully) not a network security breach.

As to whether the root cause of the bug is in Windows networking, a flaw in 802.11x architecture, a router firmware hole, software firewall hiccup, or some other problem, I remain clueless.

OK. I got it. Thanx 4 response!

My case is same. The below is just 4 ur reference. Maybe it could be helpful to determine z cause of this issue.

1. Small home network of 3PCs - 2 wired + 1 wireless with Intel 4965ABGN internal card - all PCs are Windows 7 Ultimate x64 OS and secured by Symantec Norton Internet Security v17.8.0.5 (year 2010 edition).

My network access point (AP) is ASUS WL-500W router. Z wireless settings of this router are: N mode only + security by both WAP2-Personal & WEP-128bit + to accept only z wireless adapters with specified MAC addresses. Z other router settings are: internal Internet Firewall is disabled + my wireless laptop is set as DMZ i.e its exposed to Internet.

2. There are a plenty of other wireless APs around: most of them are G but a few are N as well, almost all are secured. (It's easy to see all wireless networking around by PassMark WirelessMon v3.1 Build 1005 Professional as installed onto my wireless laptop)

The only one alien AP (some D-link DIR-300), which is visible not only in network infrastructure of my wireless laptop but in Norton network map of this laptop as well, is both N and Unsecured! So this is z only one unsecured WiFi N AP around me.

Of course this DIR-300 unsecured N AP is visible in network infrastructure + Norton network of my wireless laptop ONLY, not in both wired PCs! And so far my actions regarding this matter were limited by blocking this alien AP in Norton network of my wireless laptop

By z way, I never tried but believe it possible for me to connect to this unsecured N AP. On z other hand I'm not able to really connect/intergate/configure it into my network because this required some hardware 8-digit PIN of that DIR-300...

Pls prompt here if/when u'll find any solution.

Thank you.

P.S. Sorry I forgot to mention - the Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings of Windows 7 Ultimate x64 OS of my wireless laptop PC are: both Work & public profiles - Network discovery turned ON.
