Question about D-Link Computers & Internet

D Link 641 Router won't recognize my computers IP address

One minute I had internet connection and the next I didn't. It's related to Zone Alarm becaue after I updated zone alarm I lost connections. If I by- pass the router I get on the internet. The details section shows just the router address (control panel - internet connections - support - details) 192.168.0.1 and not my computer addresses. If I by-pass I get all three computer addresses. I uninstalled Zone alarm but it didn't help.

You may find this discussion on the Zone Alarm forum site helpful. Apparently, there have been a couple of issues with ZA updates either being incompatible with MS patches or messing up their own databases. The thread includes some diagnostic recommendations and some possible solutions.

Step 1 Verify physical connectivity by checking for solid link lights on the device. If you do not get a solid link light, try using a different cable or connect to a different port on the device if possible. If the computer is turned off, the link light may not be on.

Step 2 Disable any internet security software running on the computer. Software firewalls like Zone Alarm, Black Ice, Sygate, Norton Personal Firewall, etc. might block access to the configuration pages. Check the help files included with your firewall software for more information on disabling or configuring it. Note that in some cases just disabling the firewall/antivirus software may not help, you may need to uninstall and reinstall the software.

Step 3 Configure your internet settings. Go to Start > Settings > Control Panel. Double click the Internet Options Icon. From the Security tab, click the button to restore the settings to their defaults. Click to the Connection tab and set the dial-up option to Never Dial a Connection. Click the LAN Settings button. Nothing should be checked. Click OK. Go to the Advanced tab and click the button to restore these settings to their defaults. Click OK out to the desktop and close any open windows.

Step 4 Check your IP address. Your computer must have an IP address in the same range of the device you are attempting to configure. Most D-Link devices use the 192.168.0.x range.

If you are attempting to configure a D-Link router, then make sure you take note of your computers Default Gateway IP address. The Default Gateway is the IP address of the D-Link router. By default, it should be 192.168.0.1.

If you are attempting to configure an Access Point or Print Server, you may need to configure your computer with a Static IP Address in the appropriate range.

To set your computer with static IP address:
Windows2000/XP: Control Panel > Network Connections > Local Area Connection > Properties > Internet protocol TCP/IP > Properties...
Windows95/98/ME: Control Panel > Network > TCP/IP protocol for your Network Adapter > Properties...

IP address: 192.168.0.2
Subnet mask: 255.255.255.0
Gateway: 192.168.0.1
DNS: 202.129.64.198 (or whichever your provider is using)

Step 5 Access the web management. Open your web browser and enter the IP address of your D-Link device in the address bar. This should open the login page for your the web management. Use the instructions provided with your product to login and complete the configuration. There are several more FAQs that cover the configuration of the different D-Link Gateways, Access Points and Print Servers.

I got this from their support page. Hope this works out for you :D

I have a Buffalo WBMR-G54 ADSL Router. The local IP address of the router is 192.168.1.1. My Medion desktop computer connects connects to my Buffalo router using an Ethernet cable. I use the wireless...


> Zone Alarm free firewall and Avast antivirus have been installed on both computers

Your router is already acting as a "firewall" to block "unsolicited" traffic from reaching the computers on your LAN. So, unless you use Zone Alarm to block "outgoing" connections
(such as a computer-virus would try to make when "calling-home", there's little benefit
to using the Zone Alarm software.

> If I use Internet explorer to connect to http://myname.dyndns.org, Internet Explorer does connect successfully to the network. However, it invites me to enter the username and password for my Buffalo WBMR-G54 router - not for the storage drive.

While you are "forwarding" TCP port 21, you are not "forwarding" TCP port 80 (as used by the 'http://' protocol). So, when you connect from the Internet to your "public" IP-address, it is the router that responds, rather than one of your computers inside your LAN.

IMHO, it is "bad" that your router's web-interface is "exposed" to attacks from the Internet.
Either "forward" TCP port 80, or configure the router to use a _different_ port number for "remote management".

> If I enter the Router user name and password, that allows me to access the Router menus via the Internet, which confirms that my account at DynDns has translated the IP address successfully.

Correct. Hopefully, you're the only one who knows the correct username/password, and there is nobody that is doing "brute-force" attacks on your router, trying to login to "hijack" your router.

> if I use Internet Explorer or FileZilla to access ftp://myname.dyndns.org, I cannot connect to the router

Correct. The 'ftp://' protocol uses TCP port 21, which the router is "forwarding" to one of the computers on your LAN.

> or the storage drive - so I cannot access any of my files remotely.
> FileZilla reports -Status: Resolving address of bob1944.dyndns.org
> Status: Connecting to 78.144.xxx.xxx:21...
> Status: Connection established, waiting for welcome message

So far, so good.

Is FileZilla expecting a "specific" content in that "welcome" message, or will "any" response be "close-enough" ?

On a computer on the Internet, open a command-line prompt:

Click Start
Click Run
Type CMD
Press Enter
Enter FTP bob1944.dyndns.org
Press Enter
Do you get a "connecting" message?
Do you get a "connected" message?
Do you see the "welcome" message?

Note that the FTP protocol usually uses _two_ ports for File Transfer:

* port 21 for "control" (sending/receiving commands/responses)
* a "random" port for "data" transfers (including directory-listings)

It's this "random" port that your router is not forwarding.

However, some FTP-clients (probably including FileZilla) and some FTP-servers
support "passive" mode, where both the "control" and the "data" connections "share" port 21.

So, configure FileZilla to use "passive" mode, and _hope_ that your FTP-server supports "passive" mode.

Router works but internet to computer does not.


Your pc might be using a static IP address. Make sure its on automatic. Go to Control Panel, Network Connections. Right-click on Local Area Connection and click Properties. Look for Internet Protocol TCP/IP and double click it. Select Obtain an IP Address Automatically and Obtain DNS Servers Automatically. Click OK all the way out. Also disable any firewall you have like Norton Firewall, McAffe, Zone Alarm and the likes.

Loss of internet connection when going through router


Your laptop seems to be hooked to your neighbours unsecured network automatically and it is going online with that. About comcast, when you connect a router to the modem or a computer to the modem, the modem has to be rebooted to give a valid IP to the connected device. If the modem is not rebooted the computer or the router will get 192.168.x.x IP address which is called private IP address.

Problem connecting to the net


You router may be set to be DHCP enabled so that it allocates the ip addresses automatically to each pc, so check that the pc's network card with connection problems is set in the properties on the TCP/IP line is set to obtain an ip address automatically. You can also try, Start>run then type ipconfig /flushdns to clear the pc ip address and dns. and restart pc. Lastly if you pc is both network cabled and wireless, ensure one or the other is dissabled as this can confuse the ip adress alocation.
