What default ip address d-link access point dsl-2640u

Hi,

I think a functional explanation may be of some assistance to you.

The IP address is assigned to the server or client software, but not to the physical workstation which the software or device is installed.

D-Link and virtually every other provider uses IP addresses from a Private IP Address class, which is special class of IP addresses that is reserved for private local networks (not to be confused with Virtual Private Networks, or VPN).

The default IP address is 192.168.0.x and assigned automatically. The most common IP address in any local system is 192.168.0.1.

Over the years, I've found that it is unnecessary to manually TCP?IP settings unless the automatic settings or configuaration has failed When I do have to change the settings, the following are used on Local Area Networks (LANs):

IP Address 192.168.0.1
Subnet mask 255.255.255.0
DNS Do not change
Gateway IP
Address None because the default should be 192.168.1.0 or whatever was
automatically assigned.

Some additional information that should assist you in better understanding a LAN.

The SSID (Service Set IDentifier) is a token which identifies a 802.11 (Wi-Fi) network. The SSID is a key which is set by the wireless network administrator. You must know the SSID to connect to a 802.11 wireless network. However, the SSID can be discovered by network sniffing/scanning. By default, the SSID is part of the packet header for every packet sent over the WLAN.

SSID access points continuously broadcast radio signals which are received by client machines if enabled. Based on the automatic or manual configuration, the client can connect to the access point. A SSID is generally 32 bit long, but when displayed to the user, it is projected into a human readable ASCII format. Multiple access points can possibly share the same SSID if they are for the same wireless network. Many wireless access points support broadcasting multiple SSIDs, permitting the formation of Virtual Access Points. Such Virtual Access Points partition a single physical access point into many logical access points, each of which can have a special set of security and network settings.

SSID Security Issues

Every user of the network must configure the SSID into their system. If the network administrator seeks to lock a user out of the network, the administrator must change the SSID of the network, which will require reconfiguration of the SSID on every network node. Some 802.11 NICs allow you to configure several SSIDs at one time.

Default SSID's

Most 802.11 access point vendors allow the use of an SSID of "any" to enable an 802.11 NIC to connect to any 802.11 network. This is known to work with wireless equipment from Buffalo Technologies, Cisco, D-Link, Enterasys, Intermec, Lucent, and Proxim. Other default SSID's include "tsunami", "101", "RoamAbout Default Network Name", "Default SSID", and "Compaq".

Every time a client connects to the wireless network, the SSID is communicated in plain text format, which can easily be sniffed by eavesdropper using sniffing applications like Kismet. Hence, additional security techniques are required to be implemented in order to enhance the wireless security.

All the best

Here is a direct link to show you how to secure your router, now you will need to reset your router to default settings before securing to do that press and hold the reset button located on the back of the router for 15 seconds or until router resets, you may need a paper clip to access the reset button.

You can get logs and list of MAC addresses accessed router both wireless and wired using Router Commander software.

Hi, here's how you can find your access point's IP address:

The access point is also your default gateway, because it's the device that you use to access the Internet, right? Open up a command prompt window (go to the Start menu, click on Run, type "cmd" and then hit Enter) and type "ipconfig" and hit Enter.

A bunch of information will appear. The one you want to look for is the one called "Default Gateway." The IP address that appears following "Default Gateway" is your access point's IP address.

Please rate this solution based on how helpful it was. (If you still can't find the IP address, add a comment and I'll be happy to reply.)

i have a dlink dsl2640u when i go in 192.168.1.1 and try to turn on the wireless and save it reboots 3 to 4 times then it stays on but the wireless is off any help

hi

firstly check to see if the wireless is set for wireless access based on MAC address filtering

also check to see if both the laptop and the wifi router are communicating on the same channel

If you have a computer hooked up to router, go to command prompt (Start - Run - cmd, then press enter), and type in ipconfig. The router's IP address will be the Default gateway address.

If no computer handy, most default router IP addresses are one of the following:
192.168.1.1
192.168.2.1
192.168.1.254

http://192.168.0.1/ try this or reboot the router...

Have you tried turning DHCP on?

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.
