When I connect my modem dorectly to my pc it works fine with IP address 192.168.1.33. When I go through My D100 I have no connection anf the IP has changed to 192.168.0.100 If I reinstall on dynamic IP addess from the oginal CD, it works for a moment then reverts to the wrong IP. Have tried to update thr programb but it deems not yo be supporten

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
