Yes, this can be a problem with the modem that you have first thing that you need to do here is to reset the modem and reconfigure it back, but if after that still have the same problem better contact your ISP and ask them if everything is working from their end...

Hope that helps...............

SOURCE: ARRIS Modem + D-Link router = no internet

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.

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

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.

Connecting modem to WAN port then any lan port to computer provides no connection. straight from modem to comp is ok.


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)

HOW CAN I GET MODEM ACCESS CODE ON SPEEDSTREAM 5100


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.

If it is also a modem you must contact your isp and give them your mac address on the router( located on the bottom usually ). If it is DSL you must enter in the correct PPPOE information so the router can dial into your service.
