I have no internet connection with the router but can surf without the router and only my modem

Hi, did you try out the procedure presented on page 16 of this manual?

http://www.belkin.com/networking/manual/MAN_F7D6301_v1_8820-00697_Surf_N300_N_Router.pdf

Sounds like your router is connected to the modem, but the modem is not connected to your ISP. Is this a new connection or a sudden problem? Unplug power to modem and router. Plug in modem first, then router. Do you need password for ISP? If connected, recommend downloading Netgear Genie for your WNDR3400.

I have a similar problem. The common denominator seems to be the SB5101. I have a brand new Belkin Surf 300N, same issue. The modem will not give DHCP to the router. I can connect fine via ethernet to the modem directly.
This modem seems to be a dinosaur.

With an Ethernet cable, connect your computer _directly_ to the cable-modem (or DSL-modem), bypassing the D-LINK router.
Now, can you web-surf?

Hi,

You may want to press and hold (using a pen or a paper clip) the reset button of the router for 30 seconds and then unplug the power of the router. Turn off the modem, wait for 10 seconds, turn on the modem, and then the router, and make sure that the modem is connected to the internet port of the router and PC to the ethernet port (1, 2, 3 or 4). See if the router will obtain an IP address from the modem. If not, download here http://www.linksysbycisco.com/US/en/support/WRT54G2/download the latest firmware for the router.

Ensure that you download the correct version for the router.

If the internet is not working first thing to check here is the internet connection from your modem without the router, make sure that your computer can access the internet when computer is connected directly to modem, if no internet without the router you need to contact your ISP for that, but if there's internet without the router you need to reset and reconfigure the router.....if you have the setup CD of the router just run that to reconfigure it back.........

Hi,

Try the DSL modem directly connected to the PC.No D-Link Router(powered off and disconnected). Verify that the PCcould surf/browse/connect to the Internet. Go to Start, Control Panel,Network Connections, right click Local Area Connection, Properties,scroll down to/highlight Internet Protocol (TCP/IP), Properties button.Get the IP Add, Subnet Mask, Default Gateway and DNS assigned to the PC(write this down. This will be your WAN/Internet IP settings). Then Disable DHCP of your modem if it has one. OK, close, save or whatever is applicable.

Disconnect the DSL modem from the PC. Connect D-Link Router to PC (wired/LAN) without the modem connected to the router.Go again to Start, Control Panel, Network Connections, right clickLocal Area Connection, Properties, scroll down to/highlight InternetProtocol(TCP/IP), Properties button. Tick "Use the following IPaddress". Enter this IP Add 192.168.0.10, Subnet Mask255.255.255.0,Default Gateway 192.168.0.1 and the DNS from what youhave written down earlier). This will be your LAN IP settings. OK,close, save or whatever is applicable.

Open a browser and log into the D-Link router (192.168.0.1, using "admin" as a username and no password). Do not run Wireless Network Setup Wizard. In WAN/Internet/Modem setting of router enable/check Static IP Add.Usethe IP numbers previously assigned to PC that you have written down asthe router's WAN/Internet/Modem IP settings. OK, close, save orwhatever is applicable. Reboot router. Connect DSL modem to router.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

You may be running into a problem of your ISP only allowing one computer on the internet. while the internet is on can you access the internet from the desktop comcast originally setup?  If so that is more then likely your problem.

I have comcast myself and they told me they do not allow home networks. I fixed that problem by using the mac address cloning feature in my router.

The setup cd is also junk, all you should really need to do is:
1. unplug modem, router, and turn off computers
2. Plug modem into router
3. Plug computers into router (don't worry about wireless right now)
4. Turn on modem, wait 20 seconds or so for lights to set,
5. Turn on router. again wait for lights to set
6. Turn on ONE computer that is hard wired into the router
7 Try to surf the net.
8. If successfull try to connect wireless computers (Without using cd) and see if they surf.

If not call comcast and see if your computers are trying to obtain real-world ip's instead of LAN ip's like they should.
If so, you'll need to enable DHCP on the router.

HI,
  Actually in short  "you NEED A MODEM;"
In order to connect your router you need to connect a modem in "bridge mode'( bridge mode is nothing but a configuration on the modem)..


this is a picture of  rear side of a  router,,, you have to connect the modem into the wan port of the router (above),, and in port number 1,2,3,4 you can connect your computers,
