    Please help me!

    I have the same problem, with the same message telling me to contact my ISP. But the fault does not lie with them, since I can connect fine without the router. I've tried the following:

    1) Logged on to DIR-635 at IP no.

    In status/wan window released and renewed connection severeal times, new IP Addresses are then assigned, but it still does not work.

    2) Turned off power to DIR-635, waited 5 min, turned on again, same situation.

    3) Used the "reset" button to factory settings. Configured DHCP connection manually. Didn't help.

    (I should perhaps mention, that I have temporarely disabled the wireless function, so this problem applies to my connection through cables)

    Any help is highly appreciated,

    I got excatly the same problem. I tried to change the IP to, only resulting to that the router dissapered from my computer. Tried also to lock the WAN down to 10Mbps, with no changing whatsoever only that the connectionspeed was much lower. I am using a Speedstream Ethernet adapter with a samsung Xpresslink router. Still, doesn't seem that thats the real problem

  • xiaoxiao Feb 15, 2008

    My problem is the same:
    When I try to install the router and use the software in the CD, everytime I come to the step where the software is trying to connect to the internet this message pops up:

    "A problem has occurred when trying to access the Internet. Please check your DSL/Cable connection and verify your Internet connection settings"

    I have no problem with the internet connection when the router is not attached. I can't install it through the Browser either, because the connection goes off and on all the time... someone who can help me with my problem?
    I can say that my Internet connection is cable, and I have been using a switch to connect to my two computers I have, if these information are helpful...

    I´m going nuts with my D-Link DIR-635! Whenever I use a wired desktop connected to the router, while another wireless computer is connected too, the network/internet connection drops almost immediately. I can use 2 or 3 wirelesses computers at the same time and have no problem. But if I start my PC wired LAN the whole network drops. ANd the it starts a connect/disconnet cycle, almost endless. And it´s been like that since for several weeks now, tried new firmware 2.24EU and it does not solve the problem. Now I installed and old DIR-514 and everything is perfect, no connection drops with my wired PC, and 2 - 3 other wireless devices at the same time. Off course the wireless speed is lower, but I solved temporarily my headache!

How I have solved my problem with the wired computer to a DIR-635 router:
- downloaded latest firmware from (as posted here before)
- reset the router ( keep just the power cable connected to the router, press the reset button and switch off/on while holding the reset button pressed, off/on again with reset pushed down, release reset button, connect LAN cable between PC and router, access router and all the configuration using the wizards)
- while configurating your Internet connection (I have the wizard option) it is important to use the option "clone MAC address from your PC", the one you used to connect direct to the cable modem.
- Follow next common steps to configurate your wireless network, etc.

Right now I'm having my PC wired to the router plus three other desktops via wireless and a wireless Canon printer.
Everything is working fine, no network drop, no internet drop. Perfect as it used to be.

Hi, I am assuming that you can connect to your router's web based interface ( On a PC LAN wired to the router, open a browser; Type ""; Log-in username/admin and password/(blank); Go to Tools > Misc and the option to select the WAN speed (bottom); Lock the speed down on the WAN port of your router to 10Mbps (Some versions do not have this feature). Hope this works for you. If not pls post back with your modem brand/model. You may also want to log the IP settings (IP Add, Subnet Mask, Default Gateway, DNS Servers) of the PC that is directly connected to the modem when you can access the Internet when not using the router. Good luck and kind regards.

D-Link DIR-635 Wireless N Router won't install

hi! I will be more than glad to assist u in this concern. I encounter that problem as well. I have a dlink as well. I follow the cd installation and it wont detect the modem or internet. but if the computer is connected to the modem it works..what i did. i didnt follow the cd installation, I set it up manual by typing at the url of your brower, that is the ip add of the router and it will ask the username and password, by default the username is admin and the password, just leave it the setup page, select on manual internet connection setup.. there is an option for dhcp-which is auto detect, static ip or pppoe. but first check what kind of setting u have with ur isp, if u are using a username and password, u have to select the pppoe, if the isp provide gave u a static ip address u have to select static.. to know your ip address settings, click start, run and type cmd and it will show dos prompt, from there type ipconfig/all, it will list the ip address, subnetmask, default gateway, dns server.. I hope this will solve ur concern..

DIR-300 router and broadband ISP connection,is NAT possible?

With a cable broadband connection, the cable line comes into the cable modem. The cable modem does the work changing the cable signal to a network connection and sends an I.P. address to the computer. With some cable internet providers you can hook the network cable into the in port on a router, wireless or wired, then hook up computers to the router. At this point the router gets the IP from cable and uses it's own IP routing for your internal network. Some broadband providers control your access by the computers mac address which registers with the vendor. If this is the case then the easy way to make it work is to get a router which can clone a mac address so the vendor still sees the same mac address.

I have just purchased a dlink dir 635 router and am trying to set it up on my Bigpond cable broadband internet. previously I had only a Motorola SBG900 gateway between cable and pc. I now have the new...

The motorola sbg900 is acting as a router itself. I'm assuming this is what you've got?

So first, go into your d-link router settings and make sure the THIRD number in the IP address is the same as your modem's ip address. This third number is the "subnet", and it must be teh same for both router and modem.

e.g. if your motorola users ip, make sure your d-link is set to Make sure the fourth number is different, but the 1st 2nd and 3rd numbers are the same.

You can figure out what your motorola's ip is by connecting it to your computer, make sure your interent is working, and then run "ipconfig" from a command prompt window. Look for the "Default Gateway" IP. That's your motorola's ip address.

Once the IP addresses match, go into your router's settings and disable the "DHCP server".

Next, plug a network cable to go from one of the LAN ports on your motorola to one of the LAN ports on your d-link. Note that it is LAN port to LAN port. The "internet/wan" port on the d-link is never used for anything.

At this point your d-link will be operating like a "Switch", it knows it is just an extension of your existing network and it won't collide and cause you problems like it was before.

Click on Setup / Manual Internet
Select Dynamic IP under "My internet connection is"
Click on "Clone Your PC's Mac address"
Click on Save settings, if it ask for reboot click on reboot

Once your are in the router, turn the modem on first then the VoIP.
After the modem and VoIP has finish rebootin
Click on the status tab of the router and check uder the "WAN"

DIR-635 can't access the internet

I think you have wrong configuration of your router.

1. Some xDSL Internet Service Providers may assign a Fixed IP Address for your Broadband router. If you have been provided with this information, choose this option and enter the assigned IP Address, Subnet Mask, Gateway IP Address and DNS IP Address for your Broadband router.
2. If you connect to the Internet using an xDSL Modem and your ISP has provided you with a Password and a Service Name, then your ISP uses PPPoE to establish a connection. You must choose this option and enter the required information.
