Question about Routers

1 Answer

Netopia DSL Router (DHCP Server) was giving address to connect to Internet

Windows XP on Lenovo laptop (T60p and T42p)
-DHCP wasn't giving address to connect to Internet
-Did every possible thing to fix it (checked firewalls; drivers; disabled, enabled, etc)
-At one point I saw error 031 -- relates to DHCP connection
-Only solution I had was to reset the DSL router (turn off/on)

Question is why did I have to reset the router?
Note: Unable to do an "IPCONFIG/RELEASE *" -- it had given a 169.x..x.x address.

Thanks.

    Netopia ADSL Gateway 3346N-002

    4 port 10/100 Ethernet built-in



    This device has been, and continues to, give out DHCP addresses, so the config is OK for DHCP.



    I'm thinking the issue is more on the laptop side -- drivers, firewall, some network configuration.



    Hope this is helping uncover something.

If this is a DSL Gateway Router, check the settings on the modem and make sure that the DHCP server is enabled.
it woould be of great help if you could provide the exact model number of the Netopia modem so that I could check if there is configuration page which you can access and check the settings..

How did you connect the computer to the router. If you are using a DSL modem it will have a DHCP server in it that is allocating IP addresses across your network. If you added the router to the computer via a hub or network switch what is the computers ip .
address. Remove the WI FI router - turn off P.C and then Go to cmd or dos prompt if windows based system and type in ipconfig and press enter to see if ip addresses are 10.0.0.2 if they are your dlink router uses 192.168.0.1 so you need to make the dlink router ip addressand subnet setting to match the Modem ip addresses of the DHCP server. Change the ip address of the dlink router to be 10.0.0.2 and change the modem to allocate DHCP IP addresses from 10.0.0.10 to 10.0.0.255. Only do this if IP addresses are 10,0,0,1 to 10.0.0.,254 on the desktop p.c with the dsl or cable modem connected.without the router being involved. (you may need to ask the ISP what the user name and password is of the modem and it should be ip address xx.xx.xx.1 so type this into a browser to change the modem settings. 10.0.0.1 or 192.168.0.1 just remember if the modem is 192.168.0.1 so is the Wi router from d-link and you will have an ip clash problem)
. How do you do this by ethernet connection from only the desktop directly with only the Wi FI . router. Go to a internet browser and type in the URL 192.168.0.1 and then change the router ip address to match what the DSL modem DHCP issues..
Page 14 of Router instructions see http://files.dlink.com.au/Products/DIR-615/Manuals/DIR-615_C2_Manual_v3.10.pdf
in the manual it states to use a direct ethernet connection for the setup program but you need to be connected to the internet for it to work but if the IP addresses are wrong or clashing will have no internet. You also want to set the modem as the DCHP server and disable the DHCP server in the set up of the wi fi tand set the WI FI router default gateway as the ip address of the Modem. if any DHCP server options in the WI FI router sert to the modem ip address. .

Title: Setting-Up a Wired Computer to Obtain an IP Address Automatically Article ID: 4033
Configuring a wired computer to get an IP address automatically will enable it to get an IP address from a DHCP server. Instead of manually entering the IP settings which will consume much time, performing this procedure will ensure that the computer will get the correct TCP/IP settings.
Configuring a computer to get an IP address automatically is useful when:
  • Connecting a computer to a network with a DHCP server. Ensuring that the computer is getting the correct TCP/IP settings.
To configure a computer to automatically get an IP address, you have to check the TCP/IP properties of the Ethernet Adapter installed on the computer. Follow the steps below for instructions.
NOTE: Make sure the wired computer is properly connected to a network with a DHCP server.

Connecting 2 routers (ASUS WL-500W and D-Link DSL-G604T Wireless)


This will give you a "Double NAT" setup. Meaning, Your D-Link router is connected to the external internet address assigned to you by your internet service provider. More than likely this is a DHCP address you do not control. Your D-Link router is then translating the address to the 192.168.1.x network. This is the first NAT translation. You are then connecting the ASUS router to DLINK, causing a second NAT translation. (Internet ADSL --> D-Link WAN Port --> D-Link Lan Port --> ASUS WAN Port --> ASUS Lan Port to computer/server/etc. ) If both of your routers are giving out DHCP addresses, then this is all that is required.

Router Connectivity


It will be one of two things or both - either your computer is not setup for DHCP or your router is using the same IP address as your ISP or both.

To check ISP IP address connect your computer to your modem then: from start => run => CMD (hit enter after this)
a command window opens, type "ipconfig /all" without the quotes.
The line with "IP address" gives you your ISP IP addr.
Compare this with what you get from your router manual if they are the same then do the following:

To configure your computer to use a DHCP IP address, go to the Control panel => network connections => Properties (right click on your default connection) => double click Internet protocol (From general tab) => (a new window pops up) from the general tab ensure that "obtain an IP address automatically" is selected.

To change the IP address of your router check your manual and do the following:
IP Addr => 10.10.1.1
Sub net mask => 255.255.0.0
Default gateway => IP address from your ISP
Make sure to the router is set to act as a DHCP server.

You should be up and running.

Netopia losses connection to internet and to server and vp phones


The Netopia Is a business-class router. Not clear from you question are you running Small Business Server or Windows Server 2003? If its the former, it has a wizard that will configure your LAN & the Netopia.
You can configure the Local IPs on the Netopia in the DHCP settings in expert mode.
The VP (VOIP?) phones are acting as a DHCP server & re-configure the network to their defaults.
Any 1/2 decent IT person (witth some real qualifications) could figure straiten this out...beware of "Techs"

Wpn 824 wireless issues.


if you have set up the wireless connection and enable it in the router, i assume you have disconnected the wired RJ45 cable to the pc, if not do so, as the pc's ip address is still being sent to the wired adapter and needs to be giving the wireless adapter an ip address itself as you cannot have two. Either remove cable or dissable the wired network card and ensure you enabled DHCP in the router settings to automatically give the pc an ip address, ensuring that thw wireless card is also set to obtain an ip address automatically in the TCP/IP properties of the wireless network adapter.
