The Dell 2300 has been working fine for the past 6 months with a Comcast cabel modem and a Dell desktop between (all connected by cat wires). Just recently the wireless and internet stopped. When I connect the cable modem to the desktop internet works fine. After unplugging and resetting the Dell 2300, all pertinent lights turn on steady (green) and no connection, land or wireless.

Re: All the lights are on, but no internet
Hi there you can try this locate your router in your internet connections and rightclick on it and look for repair and click on it now the comoputer will try to renew the ipconfiguration and address and hopefully this will get you going again once it is done you should be able to go to the router and click status and see if it says aquiring network address and wait to see if it does ok please let me know how this goes for you

If you have a wireless router and it is connected to the DSLor cable modem then -
To connect to your wireless router, the router needsits wireless settings to be configured with the SSID, encryption key etc., alsothe wireless cards in all the laptops/computers needs to be configured withthese router's wireless settings. Then the laptops/desktop computers cancommunicate with your wireless router and access the Internet via the DSL or cable modem.
The cable modem sometimes register the hardware MAC address of the connected device. So your PC may be registered and it won't accept the router now. Connect the WAN port of the router to your cable modem and power the modem off and on again. It should re-register the connected device and now your router should work.
you need to change dhcp from the modem to the router to be a different network than what your router hands out via dhcp. you will also need to set dns up in the router to forward to the upstream modem.
If you want to use the wireless portion of your router, you would need a wireless adapter installed on your desktop. If you are getting internet on your desktop then this means that your wired connection is fine to the router is fine. The WMP54G adapter will work with your router, however if you are not planning on connecting to the internet wirelessly through the router then there is no need to purchase the adapter. Hope that this helps you out.
When you reset the router, did you first shut the router down, then unplug the modem (wait 30 seconds), reconnect the modem (wait for all lights to go to "normal mode"), reconnect router to power, check for activity light on modem, wait about 30 seconds after all is powered up? If not, try that sequence and let me know if it works.
since you have a comcast modem the router should automatically pick up connection,since you have already reset the modem,what you need to do is to check whether you are going online suing the modem,once you can go online using the modem,reset the rotuer as well,connect all the devices properly(the cables should be in the appropriate ports)turn off all the devices for 60 sec and then turn the modem,wait for the light to be steday,turn on the router and then the computer and check if you are being able to go online i am sure you will be,incase you are stuck let me know ffurther...
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.
Only real trouble shooting I can suggest is power cycle the modem and router. If you have the Comcast Digital Voice modem make sure you push the reset button on the back as there is a battery in the unit and unplugging won't do anything.
