Trying (no success so far) to download the router manual before answering. Now knowing your internet connection architecture, Drakeo's posts make sense.

@Drakeo: does the ISP look for the MAC on the modem, the router or that attached computer? Are the modem and the router working in bridged mode? Otherwise, how does the computer gets a public IP address (which seems a very scary arrangement!)?

Failing all else, you could check the manufacturers web site for firmware and instructions on how to flash the router. I've had excellent results flashing replacement firmware from dd-wrt. Looks like your router may be supported, depending on the version.

http://192.168.2.1 should be right according to:
http://en-us-support.belkin.com/app/...IqM00tag%3D%3D
The product info is all there for my router if that helps anyone. IDK how to update firmware if 192.168.2.1 just refuses to open.

I'm confused and do not yet have a clear picture of the network, the networking devices, the computers on it and what (if anything) is still working.

To recap and ask some more questions for elucidation:
  1. The problem device is a Belkin Wireless G F5D7230-4, a wireless access point (connects wireless clients to wired network) and wireless range extender (connects wireless clients to wireless network -- used when signal strength is too low). It has a single RJ45/Ethernet socket.
  2. The Belkin was used "to set up my connection and a password etc. I did this from my main PC running Ubuntu".
    Questions:
    • was this setting up the cable company's username and password?
    • was this a connection to the Internet?
    • wired or wireless?
    • how was the connection set up?
    • do you want to use the Belkin as an Access Point or as a wireless range extender?
  3. Other computers were able to connect to the Internet via wireless.
  4. Was OK like this until trying to add an older PC with a D-Link wireless card running Puppy.
  5. Question: What does "what I thought I was doing through a wired connection" mean in "So what I thought I was doing through a wired connection after no success connecting it wireless, even though other computers could connect to the network no problem, was removing the password, etc and making it into an open network".
  6. The Belkin was re-configured in the hope of opening up the wireless. The Belkin was rebooted but froze.
    Question: what were the symptoms of "froze"? In particular, what was the state of the four LEDs described on page 5 of the manual?
  7. Now the Puppy computer cannot connect to the Belkin, wired or wireless.
  8. "The cable and that router wired port are fine cause I tested them on another computer". So some computer is able to connect wired to the Belkin.
    Question: Which computer and OS? Can we try using this computer to re-configure the Belkin?
  9. The ISP is a cable company.
    Question: which cable company? This may not matter but may help us understand how their modem fits into the networking picture.
  10. The connection to the ISP is via a cable-company supplied modem.
    Question: what sort of modem is it? Text from labels on the underside usually give the most specific information.
  11. "I plugged that wire into the router and my main PC is connected to port 1 (wired) off that router".
    Questions: What is this router? Is it the cable company's modem, the Belkin or some other device?
  12. "The netbook is yes".
    Questions: Which computer is that and what does it connect to? To the Internet or to the Belkin?
I see no reason (yet!) to believe the Belkin bricked; we have a way to go before considering reloading firmware.

To make progress we need a clear picture of the network, its networking devices and computers. Answers to the questions above would help. We need to proceed with caution so as not to break what is working.

1:Correct
2:The Cable Co.(Blue Ridge Communications) only ran a wire from my cable box and plugged into a cable modem. Then wire to my ethernet port and it connected. No username/password/software from them needed. A few days later I bought a used router from a friend and set up a passworded network from the 192.168.2.1 router access IP while wired to my main PC running Ubuntu 9.10. A few weeks after that, I tried to configure a wireless card in another, older PC that runs Puppy Linux and was unsuccessful. What I thought I was doing by making an open network, was eliminating a point of possible error. Instead, I now have no wireless at all, but wired works fine to all other computers except the one (running Puppy) I was making the changes from. I would like to have a home network set up to connect to the internet wirelessly from anywhere in my house as was possible with the way it was previously configured.
3:wireless worked b4, but not now. No wireless at all.
4:correct
5:I had accessed the 192.168.2.1 IP from a wired connection to the Puppy machine that was fully functional at the time and was changing the router config from there.
6:The router didn't freeze. My PC running Puppy froze on the reboot page of the router setup. The router was still connected to my Ubuntu PC and working fine wired. But this is when wireless dissappeared.
7:True
8:Have tried using the other computers at my disposal to configure the belkin. No luck. as I said, 192.168.2.1 will not open on my network from anywhere.
9:Blue Ridge Cable www.brctv.com
10:Scientific Atlanta DPC2100R2 is the modem
11:The Belkin
12:All PC's/laptops/etc excepting the Puppy PC can connect to internet through my network via a wired connection to the Belkin which is wired to the SA modem and to my Ubuntu box.

Thanks for all the help. Sorry if I confused you. Basically I am new to networking and made a major SNAFU I am afraid. My wireless is FUBARed but I know it's fixable...I hope. Just need to know how. Wired seems to be fine. The Puppy's wired problem can probably be fixed if I reinstall it, not a huge deal there. Puppy installs fast, even on a PC that old.

Thanks for the info

I couldn't find anything about the "Scientific Atlanta DPC2100R2" specifically but Scientific were bought by Cisco a few years ago; I think this is the specification (it's for the Cisco Model DPC2100 DOCSIS 2.0 Cable Modem - 7007012H) and this is the user guide (it's for WebSTARTM Model DPC 2100TM and EPC2100TM Cable Modems). Both took lot of finding -- Cisco is one of those companies where the marketing people dominate over the technical

Based on those documents, the DPC2100R2 is meant to be used in a very simple way; the user configures their computer(s) for automatic networking configuration and it "just works". I assume that's how it is for you now -- any computer configured for automatic networking configuration can be plugged into the DPC2100R2 and is able to connect to the Internet.

Under the hood this is using Dynamic Host Configuration Protocol (DHCP) to configure your computer with IP address, netmask, default gateway and DNS servers -- the essentials -- with values given out by the DPC2100R2. For Linux systems it helps to know that.

Back to the Belkin. It seems that it has got into a "funny" state. Assuming that it is not actually broken it should be recoverable by resetting it and then reconfiguring it following procedures in its User Manual.

First, the reset procedure. Follow the procedure on page 6, paying particular attention to the Power/Ready light to see if it behaves as expected.

Now for the re-configuration. I presume you want to configure the Belkin as a Wireless Access Point, that is you will wire it to the DPC2100R2 and then connect all the other computers to the Belkin by wireless and thus
  • to the Internet via the DPC2100R2.
  • to each other via the Belkin.
Follow the procedure on page 8. In step 1.2 you will be connecting whichever computer you are going to configure the Belkin from directly to the Belkin -- AFAIK you do not have a router, or an Ethernet switch-or-hub.

Presuming you do not have a Windows computer, you cannot follow the procedure in sections 2 and 3 so skip to "Using the Web-Based Advanced User Interface" on page 14. We are going to do the Ubuntu Karmic equivalent of what it says there.

During the reset, the Belkin set its IP address and netmask to 192.168.2.254 and 255.255.255.0. For a computer to connect with it, the computer must be in the same network range. We are going to use 192.168.2.200 and 255.255.255.0. This is known as a "static" address because it is fixed, unlike when getting the address by Dynamic Host Configuration Protocol (DHCP) when the computer may get a different address each time.

Unfortunately I don't have Ubuntu. I tried to find a web page showing how to do this using GUI tools (Network Manager?) but found only pages saying Network Manager is broken and the best thing to do is remove it! That's what I did when running ubuntu Hardy. Seems like you have to use the command line to edit the /etc/interfaces file and then restart networking. Procedures here and here.
  1. Make a backup copy of your existing interfaces file!!! You will want to restore it after configuring the Belkin. Something like this
    Code:
    cd /etc
    sudo cp -p interfaces interfaces.bak
  2. The second procedure suggests removing network-manager. I don't think that is necessary.
  3. The procedures suggest using vi, nano or kate to edit the file. If you are not comfortable using any of them, post back for a workaround.
  4. Use these settings instead of the ones in the procedures:
    address 192.168.2.200
    netmask 255.255.255.0
    network 192.168.2.0
    broadcast 192.168.2.255
    gateway 192.168.2.254
Ensure that your settings have worked by using the ifconfig command and inspect the values for eth0.

Now continue with "Logging into the WURE" on page 15.

I don't know much about wireless so can't help much from here on. On page 22, I think you want "Wireless Access Point" mode. Hopefully that will make the Belkin transparent and computers attached by wireless will be able to get their network settings from the DPC2100R2 by DHCP. Once you have the Belkin working as you want, it's useful to save the configuration as explained on page 35.

When you have finished setting up the Belkin, copy the /etc/interfaces file in case you ever need to use it again and restore the old one, something like this (assuming your original interfaces file was backed up as interfaces.bak). This has not been tested
Code:
cd /etc
sudo cp -p interfaces interfaces.belkin.G-F5D7230-4
sudo cp -p interfaces.bak interfaces

What manual are you reading? I can't locate a manual for the Belkin. How should I log into the WURE. The only way I know how is the Web Interface...and it doesn't work still. The above steps work fine and I am still connected to the internet.

If you have done all the steps -- the Belkin is reset and the computer has the correct networking configuration -- then the Belkin is broken. It may be possible to reload firmware but that's not something I know about; all the procedures I found required that the Belkin is accessible via browser to initiate the firmware load. If it is the hardware itself that is broken, reloading the firmware will not fix it of course.

This Google search has pages about re-loading firmware, including when the web interface is not working.

I don't think this is right. I've fought with Belkin on this router and when they find out it's running through a Linux box, they told me they can't help. I don't want to flash the firmware if I don't have to...
