Need help with a crappy network set up

post #1 of 5
Thread Starter 
My girl friend is trying to get her internet to work while she is visiting her family. Her uncle has it set up so that the network is ran through his PC. He had it working for her but the username and password isn't working; so I'm wondering if there is a way to configure the network from his machine?

Right now, by the sounds of it, the modem is connected directly, via LAN, to his PC. Then he uses his second port to port-forward to whoever has a LAN connection to his rig. It asks for a username and password but the one he has isn't working.

Edit: I'm thinking of trying to get her to reset his internet sharing options (or whatever he has set up). Found this:
Quote:
Use Network Connections wizard:

1. Set up an Advanced Connection
2. Accept Connect directly to another computer
3. Select Host (PCs w/o Modem) or Select Guest (PCs w/o Modem)
4. For Host, select Modem to use.
For Guests enter name of computer to connect to.
and so on.

    I think what you really need is a simple Ethernet switcher (an Ethernet switch is basically a multitasking hub).  You would connect the LAN output of the modem to a port on the switcher, and then connect any computers needing Internet access to other ports on the switcher.  All computers connected to that switcher should then be able to connect directly to the Internet, without any special access required. thumb.gif

You should be able to reconfigure ICS (Internet Connection Sharing) to set up NAT, DHCP and routing behind the second interface.

The obvious solution would be to get a wireless router though.

If they just got a switch, chances are only a single PC would be on the internet at the same time and you definitely wouldn't have any sort of internal LAN.

    Not necessarily true: An Ethernet switch is exactly what I am using right now to send this, and every computer connected to that switcher gets full Internet connectivity because I've connected my DSL modem to that switcher.  Furthermore, each computer connected to that switcher can also communicate with the other connected computers, so I definitely have an internal LAN as well.
    If your DSL (or cable) modem has routing capabilities built-in (most do), it will work just fine when connected to a switcher.  How to find out?  Assuming Vista or later, click the network icon in the system tray and click "Network and Sharing Center."  When it opens, click "Manage network connections" on the left sidebar.  Next, find out which network adapter is connected to your modem, right-click it, and click "Status."  In the status window, click "Details..."  Then, look for "IPv4 IP Address."  If it reads something like "192.168.0.x" or "10.0.0.x" you have a routing modem, and a simple Ethernet switch will work just fine.  If not, compare it with the IP address whatismyipaddress.com says you're at.  If both numbers match, an Ethernet switch will not work, and you'll have to use a router. thumb.gif

    I didn't mention a wireless router because of the extra complexity to set up, the additional health concerns with having continual wireless signals in the house, and the fact that they are currently using a wired connection.  The switcher should simply be "buy a <$10 switcher, and maybe a short Ethernet cable, and then plug-and-play."

My old DSL modem didn't have routing capabilities. I believe my current cable modem doesn't either or if it does, my ISP has disabled it (locked down so can't really change any settings). Besides, getting a wireless router is the "safer" option as it will work regardless of whether or not the modem has routing capabilities. As for health concerns, you can always disable the wireless radio if it isn't needed.

That said, it is her uncle's house and if the uncle doesn't want a wireless router or switch installed and wants internet traffic to go through his computer, the choice is his.
