Hi,
You may want to enable the DHCP reservation feature of the router.
What is DHCP Reservation and how do I configure it?

What is DHCP Reservation?
A DHCP reservation is a permanent IP address assignment. It is a specific IP address within a DHCP scope that is permanently reserved for leased use to a specific DHCP client.
You can configure a DHCP reservation in your DHCP server when you need to reserve a permanent IP address assignment. Use reservations for the DHCP enabled devices like print and file servers or other application servers which always have the fixed IP address on network.


Step 1: Access the router's web-based setup page. For instructions, click here
Step 2: When the router's web-based setup page appears, click Setup.
Step 3: Click on Basic Setup.
Step 4: Make sure that DHCP Server is Enabled. Then, click the DHCP Reservation button if you want to assign a fixed local IP address to a MAC address.

My ip adress says unavailable


Sounds like the computer you're trying to connect to your wi-fi router is set up with a static IP address that is being reserved by your router for DHCP. To resolve, make sure your router has "DHCP" (dynamic host configuration protocol) turned on. Make sure the computer you're trying to connect to your router is set up to allow the DHCP server in your router to set the computer's IP address and DNS server address. You can find instructions to enable DHCP in your router's user manual or by searching online. You can find instructions for setting your computer's wireless adapter to allow the DHCP server in your router to set the computer's IP and DNS addresses here:

IP Conflicts in a work place


An IP address conflict occurs when two computers on a LAN or the Internet have been assigned the same IP. IP conflicts between two computers normally render either one or both of them unusable for network operations.

How IP Address Conflicts Happen

Two computers can acquire conflicting IP addresses in any of several ways:

· A system administrator assigns two computers on the LAN the same Static IP Address.

· A system administrator assigns a computer a static IP address within the local network's DHCP range (dynamic IP range), and the same address is automatically assigned by the LAN DHCP server.

· A malfunction in the network's DHCP server allows the same dynamic address to automatically be assigned to multiple computers.

· An ISP accidentally assigns two customers the same IP address (either statically or dynamically).

· A mobile computer is put into standby / hibernate mode and then awakened later.

Note that other forms of IP conflicts can also occur on a network. For example, one computer may experience an IP address conflict with itself if that computer is configured with multiple Network Adapters. System administrators may also create IP conflicts by accidentally connecting two ports of a network switch or router to each other.

Recognizing IP Address Conflicts

On most Microsoft Windows computers, if you attempt to set a fixed (static) IP address that is already active on the local network, you will receive the following pop-up error message:

The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.

On newer Microsoft Windows computers having dynamic IP conflicts, you should receive a balloon error message in the Taskbar as soon as the operating system detects the issue:

There is an IP address conflict with another system on the network.

Sometimes, especially on older Windows computers, a message similar to the following may instead appear in a pop-up window:

The system has detected a conflict for IP address...

On Mac or Linux computers, a similar message will normally appear on screen.

Resolving IP Address Conflicts

Try the following remedies for IP conflicts:

1. For networks where IP addresses are fixed (statically assigned), ensure each local host is configured with a unique IP address.

2. If your computer has a dynamically assigned address, releasing and renewing its IP address can workaround IP address conflicts.
3. If your home router is believed to have a faulty DHCP server causing IP conflicts on the home network, upgrading the router firmware may resolve this problem.

IP conflict on my home network


Hi.
If there is an IP conflict, that means that two different devices connected to your home router are getting the same IP. In this case one or more connected devices will have limited connectivity, as they will be unable to access network resources.


The following troubleshooting must be performed on one networked device at the time.

Check if the internet provider that you are using allows DHCP. Most broadband providers use DHCP.

DHCP (dynamic host control protocol) means that the IPs, instead of being static are being assigned each time by the router.

If you use DHCP, then ensure that all devices connected to the network are not set on Static IP. If there is a device that must be set on static (eg. a network printer), then change manually the device IP to a different one. Ensure that the new IP belongs to your network range.

Reset the network settings on all connected devices. On computers remove the network adapter from the installed hardware devices list in control panel.
Restart computers one by one, after removing the adapter, and allow the network card to reinstall, using driver disk when needed (ensure that you have the drivers first). It will set itself to DHCP by default.

If that does not work, then you can try changing MAC address on Windows. The MAC address is an unique identifier that is assigned by manufacturer to any Ethernet adapter. The MAC address is used by the router to determine IP. To this purpose see: Changing MAC addresses on Windows .

If still no luck , then the next step would be resetting and re-configuring the router again, using the settings given by your ISP. Ensure that you have your Internet Service Provider configuration settings before resetting the router

At this point it may be worth testing a different Ethernet adapter (eg an USB adapter), rather than resetting the router.

If all that does not work, then either the router, or one of the two network adapter is probably defective. In some case virus or malaware can also cause IP conflicts.In that case ensure that the computer is clean, and eventually replace the router, after testing PC network adapter.

Note:If your home LAN uses static settings instead of DHCP, simply check that the IP set for each device is different.

Regards.

I'm using TP-LINK TD-W8101G ADSL Modem Router to connect internet, I'm trying to connect it with Linksys WRT120N Router Wirelessly. I want to use WRT120N as access point to extend TP-LINK...


Unfortunately, you can't use two routers together in that manner. You must have a device in between them such as a switch or bridge or you'll have to disable the DHCP server settings in the second router. The second router then pretty much becomes a switch you may then use all the ports on the second router with the exception of the WAN port it must remain unoccupied. However, if you need wireless connectivity in another location far away from your main router then your only solution would be to indeed purchase an actual access point/bridge device

I'm using two Macintosh Computers. I followed the quick setup wizard, all the right lights are lit. I've reset my broadband modem, I've reset the Dynex Router. Yet I can't make contact...


Richard have you tried setting up static ip addresses on the MACs
If you have other p.c's on network with auto ip assignment then alter the DHCP server lease to 192.168.1.10 to 192.168.1.240
then make ip address static 192.168.1.241 subnet mask 255.255.255.0 default gateway 192.168.1.1 and on the other mac
make ip address static 192.168.1.242 subnet mask 255.255.255.0 default gateway 192.168.1.1

It says that my computer is connected to network and internet but it my computer cant browse in the internet


Likely a DNS problem.

1. Check to see if your router is set to obtain DNs as dynamic or static (probably dynamic). Verify the listed primary & secondary DNS servers are correct for your ISP.
2. Check router to see if it acts as DHCP server for your network to assign ip numbers to clients. If so, then verify your computer as dynamic, otherwise set static ip in the same subnet.
3. Verify gateway assignments.

Changing of I P Address


You can use any router. All routers these days comes with a DHCP server feature built-in. However, you have to ensure your desktop is set to receive ip address and dns dynamically from the DHCP server.

However, if you wish to have the same ip address always but dynamically assigned by the DHCP server and not a static ip addres, you need to go for a router that provides static dhcp ip address.

You may check Linksys, where you could find one of their model which has this Static DHCP feature.

I hope this helps

No connection to laptop.


I would imagine that you have the desktop wired to the 2wire router... Does the desktop have a static or dynamic IP? If you want it to be dynamic you will have to setup DHCP on the router to give the laptop an IP address... Otherwise set the IP on the laptop to the same subnet that the desktop and router are on, i.e 192.168.1.0... Make sure that the laptop is has a static (doesnt change) IP or its setup to receive an IP from the router or another DHCP server, if you have a DHCP server on your network... To make the laptop a DHCP client, set the wireless NIC to automatically select an IP and automatically select DNS servers, this can be done thru the control panel>network connections, then select your wireless NIC, right-click on it and select properties, on the first page of the properties menu, highlight TCP/IP then click on the properties button and when that screen appears, select the radio button for automatic selection of IP and DNS... if you will not be using dynamic IP/DHCP, you will manually have to enter the IP address, subnet mask, default gateway and DNS server IPs.... Let me know if this helps or if I can clearify something for you! Best of luck!

Static config


DHCP is superior to Static IP in every conceivable way. It is not any slower. However, when you FIRST connect to a dynamic ip router, your computer and the router have to handshake a bit, which takes a few seconds.

After that, they are at the identical speed. DHCP shields you from all sorts of trouble like colliding IP addresses, DNS server, subnet masks and gateways. It is way better and more reliable to go with DHCP.

Static ip is only useful if you *need* static ip, e.g. if you want to host a server on your router and you need the computer's dns server to stay the same.

That said, if you still want to use a static ip, here's how:

Simply disable the DHCP server in the router's settings. Also, go into the router's "status" page and take note of the DNS ADDRESS(S). You will need this later.

(Please note, if you disable the dhcp server, the only way to get back into your router and re-enable it is to use static ip on the computer, or to hard reset the router)

Then, you configure each computer connected to the router to use a static IP as opposed to obtaining it automatically. To do this in windows XP:

Go to start->control panel->network connections
Right click on Local Area Connection and go to Properties
Select "Internet Protocol (TCP/IP)" from the listbox
Click Properties
In the general tab, tick the radio box "Use the following IP address"
Type in the ip adderss you want (e.g. 192.168.0.105)
Type in 255.255.255.0 as the subnet mask
Leave the default gateway blank
Type the ip address of the DNS server you took note of earlier into the "Preferred DNS" section at the bottom of the form.

Click ok and ok and ok until you're out of all the boxes. Your IP is now static, and cross your fingers. If you did everything correct, it will work. If not, check your settings.

WRT300N Wireless Router change to DHCP


I would set the new wireless router to have a static ip address on the same subnet as the first router.  Then set the DNS and Default Gateway the same as the first router.  When computers connect they should pick up an ip from the first router.
