3Com and seeing other PCs in "My Network places"

I have a 3Com OfficeConnect DSL which seems to be picking up other PCs. If I look under the "My Network places" then "Entire Network" then "Microsoft Windows Network" I can see other PCs attached which are unknown to me. We live in the country and are quite a distance away from any other houses so I do not think these are wireless connections. The wireless is encrypted. We can even access the document folders on some. This seems to be a new issue that happened recently. If I remove the 3com and attach a Linksys router I no longer see those other PCs. What setting on the 3com could be causing this? (My wife and I are both on this router using Windows XP Pro on both machines)

Can you post a picture of the my network places window showing the other computers
It sounds like you're just seeing the shares on other computers

What modem are you using with the linksys router

I will try to post a picture. Yes they may be shared folders on other PCS but I don't think those should be visible to me. The linksys and the 3com are both modem/routers. We attach the DSL in the back and then attach our network cables to the back (4 port) of the router. With the Linksys the other PCs never show up. They only appear with the 3com.

If you have dsl you must have a modem with a builtin router or a modem and a router

The 3com may be a modem with a builtin router and it may be configured so that the computer has the public ip address

If you can't post a picture run the ipconfig /all command with the computer connected to the 3com record the results
Run the ipconfig /all command with the computer connected to the linksys record the results

The Linksys gives the 192.168.1.100 which (to me) should be the correct address. I am not sure how to get the 3com to behave in a similar mode.

Yea the 3com allocates the public ip to the computer
The linksys does nat/napt

What is the full model number of the 3com
The 3com may be able to do nat/napt like the linksys

You could just connect the wan port of the linksys to the 3com and connect all your devices to the linksys

The model is 3CRWDR200A-75
OfficeConnect ADSL wireless 108mbps 11g firewall router

Well the linksys is a backup system in case the current (3com) router dies we can replace it with the linksys until we get another. So using them both is really not what we want to do right now. I'd like to figure out how to get the 3com to behave like the Linksys but so far I don't know what setting would do that.

The linksys is useless without a dsl modem

You may be able to get the 3com to behave like the Linksys only after you know/learn what type of dsl internet connection you have now

Do you know if you need pppoe to connect to the internet
Can you access the configuration pages of the 3com

When you have a computer directly connected to the 3com do you need to click anything on the computers desktop to connect to the internet

Can you tell me what the linksys internet connection type is set to


Iguanaman

@173.195.143.x

The linksys is also a ADSL modem/router. They serve the same function, just the settings are somehow different.

The connection is 1483 bridged LLC. The IP address is dynamic. (DHCP is left unchecked) VPI = 0, VCI = 35.



Iguanaman

@173.195.143.x

and no we do not have to click on anything to connect to the internet for either modem/router

Here's a page from a linksys adsl router


























If you could post a picture of this page from your linksys or the info from this page
The vc settings and ip settings are needed to identify how the internet connection is made

Can you access the configuration pages of the 3com if you can a picture of it's configuration summary page would help


Iguanaman

@173.195.143.x

The problem there is once we set the mode to LLC bridged the modem reboots and we can never access the settings (on either router) unless we completely reset the modem back to default settings again.

There should be some specific setting that alters the way the 3com deals with the ip address (public vs private lan) and unless you know what that setting is I am not sure what the information you are requesting will provide. I gave you the VC settings and IP settings in the previous posts.

I don't want you to make any configuration changes
said by Iguanaman :

You may be right......I think the 3com is in "bridge mode" which means the computer is making the internet connection
said by Iguanaman :

I don't know enough about the current configuration to suggest changes
said by Iguanaman :

The vc settings are settings that are common for any adsl modem

It looks like the linksys internet connection type is automatic/dhcp the linksys status page should show that

I can only guess about the 3com internet connection type
You should be able to call your isp and get them to help you
