D-link problem My ISP say's that the cable modem is letting my desktop computer on the enternet and not my laptop. they the modem is holding the Mac addresses.

what OS, we can NOT GUESS your operating system.
so where are you , home or star bucks.?
what is your connection, wifi, ethernet, or others?
a desktop pc can have vast ways to get internet.

1: modem dial up (i bet not this, nobody uses this now, 99.9)
2: cable modem, sat modem, fiber modem to ISP
3: USB wifi dongle, on PC and to local router.
4: PCI card wifi. , to router.
5: ethernet wired to router or modem direct. a cable wire. CAT5/6

one can even have direct wired ethernet to the cable modem
or you might have wired to wifi router (2 ways to connect there)

NO OS stated
no connections stated.

my guess is DCS, means DHCP not found, or DNS not found.
lots of causes, but I will not attempt to answer for all 6 ways.
sorry

Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer that's registered with the ISP.
To setup a Linksys router with Cable connection you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting Devices Together
iii. Checking the Router's LEDs
iv. Configuring a Linksys Router for a Cable Internet Connection


If you need more help come back.Post / thumbs / testimonial are welcome!

RESET the router and try again

Each network adapter (in the Linksys router, or in your computer) has a unique 12-character code. Some ISPs (Internet Service Providers) will require you to "register" this 'MAC' (Media Acquisition Control) address, before they grant an IP-address to the device (router or computer). So, when you "bypass" the router, you're showing a different MAC-address to the ISP, and they are not allowing that MAC-address to get connected. Talk to your ISP.

Or, some cable-modems check the MAC-address, allowing just one or two computers to connect. Turn the cable-modem off, to make it "forget" the MAC-addresses that have connected to it.
Connect the router to the cable-modem.
Turn the modem on.
Turn the router on.
Connect your computer to the router.
Restart your computer.

Or, maybe the router really is "dead'; try the above, before choosing this option, and before buying a new router.

Make sure comp lan and wan are both activated, Make sure the ethernet cable from modem is plugged into the input slot and NOT 1,2,3,or 4

Then after all is connected, unplug main modem for 10 seconds, plug back in, then do the same with wireless router. 5 minutes later, you should be good to go.

You can access the software of you router by opening up an internet page, and type 192.168.1.1 and hit enter. It should bring you right straight to the router's firmware/software where you can change any settings if desired.

If it asks for username and password, the default is usually admin for both. (see owners manual to be exact)

HI! I bliv u are having some issue setting up ur router.. I will be more than glad to assist u. . here are the steps u need to do: 1. press the reset button on the back of the router for 20sec..while pressing the reset button, unplug the power plug and after 2secs while pressing the reset button plug it back in and press for 30secs after that unplug the router for 15secs then plug it back in..once all the lights are solid and ok 2. connect the ethernet cable to port1 of the router and the other end to the lan port of your computer.. 3. pull up ur browser then type at the url:192.168.1.1.or 192.168.0.1 or u can check the routers default gateway by right clicking the network icon on the lower right of your task bar and click on status and it will show the ip address of the computer, subnetmask and default gateway, the default gateway is the routers ip address, once u type in to the url, it will ask u the username and password, by default the username is admin and the password is 1234 or just leave it blank 4. it will show the setup page of the router. u can set the router on the specific internet setup that u have. a. if ur isp is a cable company, normaly u need to do a mac clone on the router setup page by cloning the computer that is reg to the cable company, how to determine it. ex. the computer that is reg to the cable company is a desktop or laptop, if this computer is connected to the modem directly and u can access internet. b. once u determined it u need to connect this computer directly to the router and do a mac clone and set ur internet settings to auto-dhcp..then save the settings and after that, unplug to the power of the modem and router, plug in 1st the power of the modem then once all lights lit, plug in the router, then once all lights lit, try to pull up a browser that ur computer is connected directly to the router.. ur cable connection shud be, cable from the modem will go to the WAN port of the router and connect ethernet cable on port1 going to the lan port of the computer..once u can access the internet, u can now access again the setup page of the router by typing at the url:192.168.1.1 and u can setup the wireless settings, u need to create a ssid or wireless name and a security.. 5. If ur isp is a dsl normaly they give u a username and password to connect to the internet, ur settings on the router should be PPPoe 6. If ur isp gives u a static ip address settings, u need to set the router to isp setup. a. how to check the isp of the isp given to u.. 1. click on start 2. run 3. type cmd 4. it will show a dos prompt 5. from the dos prompt type ipconfig/all 6. it will list the ip address, subnet, default gateway, dns server this settings should be type in to the settings on the router for static ip addressing.. 7. Once your done on the internet setting, go to your wireless connection settings and you can create a wireless network name or ssid, set a security by selecting wep, wpa, wpa2. 8. once all is set. save the settings and to check if your laptop can access the wireless network that you did, turn on the wireless switch of your laptop, once its on, it will show the wireless network icon on the lower right of the taskbar, right click it and select on view available network, the network name that u did should list, just select it and connect and it will ask for the password, just type the password and connect, you should be connected to the wireless network and have internet access.. 9. If you are going to hook up your desktop to the wireless connection, you need to install a wireless network adapter, install the driver and do the same thing as u did to the laptop, for the desktop no need of turning on the wireless switch, once you install the driver correctly, it will show a network icon.. if you have any query pls feel free to get in touch.. good luck

hello
When you have modem plugged straight into computer, you can access it at 192.168.0.1, should ask for modem access code, (on bottom), then you can click 'advanced' > ppp location and set it for 'on computer'. There may also be a link for technician stats, it will give you info about isp connection. You should / might be able to browse but ISP may need original MAC address of machine (network adapter} you used when 1st signing up. Or if set to PPOE, it would look for name / PW in order to access INternet through ISP.
Anyway, try (after setting PPP on computer) Modem into WAN of router, access router, set PPOE > insert Log-in name / PW and save all settings. Then try homepage, if no, have router "clone MAC address" of the Network adapter you had the 5100 plugged into. Now it should work, even if no <INTERNET> light. ETHERNET light should be constant. Have router use DHCP to address machine independantly of what ISP addresses router, which it will do when modem (having connection confirmed with DSL light)

The other way, PPP location set 'on Modem', means the modem signs into ISP and then it assigns IP address with a timeout around 20 minutes. By getting connection test results when modem is connected to computer, it may seem to make sense, by understanding how ISP knows that modem access code / MAC address, and lets the settings of modem determine if router needs to sign in or not. If PPP is 'on modem', it will be looking for the MAC address of computer, that is why you may need to clone that address into router, so the router can appear as the machine to the modem, than the router assigns net address to computer.

Hi! I will be more than glad to assist u in this concern..the router is not properly setup.. if you are using a cable modem from ur cable company provider- u need to do a mac clone on the router u have to clone the mac address of ur computer. normaly the mac of ur computer is the one register to your cable company and on the setup page of the router just selct on the internet setup, dhcp after clonning the mac address of your computer. u need to connect ur computer directly to the router and then after doing the process connect the router to the modem. if u are using a username and password, u have to use the pppoe settings on the router, if ur isp set a static ip , set it up to the router, to check the ip setting of your isp.. connect the computer directly to the modem and check if u have internet.. then click on start, run and type cmd,it will give u a dos prompt and from there type ipconfig/all and it will show u the ip address, subnetmask, default gateway, dns server.. I hope this will solve ur concern..

when you are on Cable Internet with a "modem" only connected directly to the computer, what the ISP see is the computer's MAC Address (command prompt -> type ipconfig and hit enter).

put a router (which has it's own MAC Address) in-between and the ISP wont let you cause it sees the router not the computer.

check physical connection: cable modem -> router -> computer(hard wire for this troubleshooting)

access the d-link gui and locate the “Clone MAC Address" button (supposed to clone the computers MAC Address - verify if it's the same), save settings & reboot the router.
