My D-Link DSL 300T Modem has stopped distributing IP addresses despite the setup page saying that this feature is enabled. This is leading to a constant error message as the IP address is the same as the router. I am running an iMac 2.8 Ghz and MacBook Pro with Leopard 10.5.2 on both. Any assistance would be greatly appreciated. Alex

both modem ip address same please check book the modem and install modem ip different 192.168.1.1 and 2nd 192.168.1.2

Hi there

Getting Started

Setting up a Wireless Infrastructure Network

Pleaseremember that D-Link AirPlus G wireless devices are pre-configured toconnect together, right out of the box, with their default settings.Fora typical wireless setup at home (as shown above), please do thefollowing:
1) You will need broadband Internet access (a Cable or DSL-subscriber line into
your home or office)
2) Consult with your Cable or DSL provider for proper installation of the modem
3) Connect the Cable or DSL modem to the DI-524 Wireless Broadband Router
(see the printed Quick Installation Guide included with your router.)
4)If you are connecting a desktop computer to your network, install theD-Link AirPlus G DWL-G510 wireless PCI adapter into an available PCIslot on your desktop computer. You may also install the DWL-G520, orthe DWL-520. (See the printed Quick Installation Guide included withthe network adapter.)
5) Install the D-Link DWL-G630 wireless Cardbus adapter into a laptop computer.
(See the printed Quick Installation Guide included with the DWL-G630.)
6)Install the D-Link DFE-530TX+ adapter into a desktop computer. The fourEthernet LAN ports of the DI-524 are Auto MDI/MDIX and will work withboth Straight-Through and Cross-Over cable. (See the printed QuickInstallation Guide included with the DFE-530TX+.)

SSID-Service Set Identifier (SSID) is the name designated for a specificwireless local area network (WLAN). The SSID’s factory default settingis default. The SSID can be easily changed to connect to an existingwireless network or to establish a new wireless network.

Channel-6 is the default channel. All devices on the network must share thesame channel. (Note: The wireless adapters will automatically scan andmatch the wireless setting.)

WEP- Wired Equivalent Privacy (WEP)is a wireless security protocol for Wireless Local Area Networks(WLAN). WEP provides security by encrypting the data that is sent overthe WLAN. Select Enabled or Disabled. Disabled is the default setting.(Note: If you enable encryption on the DI-524 make sure to also enableencryption on all the wireless clients or wireless connection will notbe established.)

You need to change the router's IP to avoid conflict with the modem's IP address. You just need to access the router's setup page , default is 192.168.1.1. Default username should be left blank and default password is admin. Once logged in , first page you will see is the Basic Setup page. Just look on themiddle part of this page and there you will see the IP address of the router. Most of the time, if the user has DSL connection , Linksys' IP should be changed to 192.168.2.1. Dont forget to click on Save Settings at the bottom of the page. It will then say Settings are successful. Now click on continue. You can then power off then power back on the router for the changes to apply

usually routers are setup using DHCP... on your second computer. try going to 
start, control panel,  networkconnection,  "your LAN connection",\ properties Internet Protocol (TCP/IP) (should be checked)
Obtained Ip address automatically should be selected
Obttained Dns server automatically should be selected.

if your router is not setup as a DHCP,it would require you to setup your ip address manually... let me know if this dont work, so  i can help u setup manually...

if it helps, try comparing the settings of your pc1 and pc2 (the network connection settings)

hi there ...

your isp is at&t? please verify the ip address straight to the modem if its is 192.168.1.1 and if your modem from your isp is set to DHCP or BRIDGE mode.

IF IP address is 192.168.1.1 (DHCP)
... change the LAN IP address of the router to 192.168.2.1 or 5.1 to prevent any IP conflict
by doing this :

1. access setup page of router usually 192.168.1.1
2. under setup tab look for the ip address, change it, then save
3. click on the status tab , and look for a VALID ip address

IF MODEM is set to BRIDGE mode
.... please ask username and password from your ISP coz we would need to set your router to PPOE...
1. access setup page
2. under setup tab look for INTERNET CONNECTION TYPE
3. select PPPoE
fill in username and password
select "keep"alive
save
4. click on status tab
look for LOG in TYPe ===> click CONNECT
if connected : check a valid IP address
if authentication failed verify again your username and password from your ISP

Goodluck!

It is common to have this as the default IP to connect to equipment.

I suggest you unplug your modem while you set up your router. You can also change the default IP for the router while in the settings. be sure to remember the new IP or you will have to do a factory reset to get it back to default

well, if you know how to setup the ip addresses manually both on your modem / router and on the ps3 i recommend you do that... but bear in mind that your dhcp server (on your modem / router) should prohibit automatic assignment of that same ip address with your ps3... for that you have to specify a range of automatically assignable ip addresses apart from your ps3...

if you have the dmz (demilitarized zone) option on your modem / router, set it up for the ip address of your ps3, which you've setup manually...

example:

router ip: 192.168.2.1
ps3 ip: 192.168.2.10
ip address pool: 192.168.2.100 - 192.168.2.250 (this shpould be manually setup not to interfere with the fixed ip address of the ps3)
dmz host: 192.168.2.10 (ip address of the ps3, which enables "opens" all of the ports for this ip address)

apart from that if you use any proxy servers to connect to the net, you have to specify these in ps3 settings as well...

there are a lot of threads on various forums on how to tweak your network connection to optimize for ps3...

i hope this solves your problem...

you might have configured your lan settings wrongly.

If your modem was setup for DHCP then you configure your lan to receive IP address automatically, DNS automatically.

If DHCP is disabled on the modem, you have to USE static IP Address for your lan ip and default gateway should be your modem default ip.

the default IP for modem is usually 192.168.1.1
if DHCP is disabled on the modem the sys ip is 192.168.1.3

So Configure your LAN setting as follow and Type http://192.168.1.1 in the address url.

Lan Settings:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1

click ok.
and type the above url, press enter the modem will ask you for username and password.

Good Luck.
