Hi Ajay,

The LAN (wired network) connectivity speed/data rate depends upon the networking hardware (Laptop Ethernet Cards, Switch, Router etc.).
To get 1Gbps connectivity you must have 1Gbps ethernet (LAN) card in the laptops. As Dell Latitude D620 has 1Gbps card, the problem could be with the switch or router, which may be having 100Mbps and 1Gbps ports, depending upon the equipment you are using and it is recommended that you check out the its full specification. If you connect laptop to 100Mbps port you can only get 100Mbps speed. To get full speed, it is required to have 1Gbps support at both ends.

Dont forget to rate the solution if it helps!!

The MAC address is unique to each LAN or wireless card and cannot be changed.
I presume you mean the IP address, this IP address can be fixed by you or can be automatically allocated by the router or the broadband modem to the LAN or wireless card in the computer.
For information on securing and setting up your wireless network, please click on this link and follow my instruction :-

Visit the Dell Web Site.. Use the Service tag on On under side of laptop.. and All Drivers are on the Dell Support Web Site!

This could even be the Dsl modem loosing internet sync, They will tell you its you're end and thats fine check the modem, it also could be the ethernet cards going into standby Thus turning off the wake on lan feature in bios or other software would provent the card from going to sleep.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/edwy_1a56970cf1ea4620

The CPX doesn't have Wireless capabilities, unless you get a USB Wireless adapter. For now, use the Yellow Network lead to connect it to your router or modem, and then purchase a USB Wi-Fi adapter if you want to move it around more.

Hi

Your query was quite general. You did not provide info on the model of the Xircom and the operating system installed.

Anyway, check Xircom Networking Products Support. Choose the Xircom Ethernet + Modem Adapters link for the list of models. Select the model you have. Proceed to the next page for a link to drivers and software and other information.

Hi. If Dell is correct, then yes, it would be expensive. Your other alternative is to buy a PCMCIA Ethernet Card. They range from about $20 to $40. Or, you could go with what you suggested and do wireless via a wireless router.

I have a Dell Inspiron and when it operates on batteries it automatically (by default) shuts down the wired network adapter when not in use. The solution may be to insure the network cable is plugged in before starting the laptop or to learn where in the power management utilities to turn on the wired network adapter -- I believe it can be done permanently at the cost of reducing battery operating time overall. It can probably also be done on a when needed basis. My Dell currently does not have windows on it and the operation on my machine may not be the same as on a Latitude. When this happened I used to get little balloon notices from a systool bar icon, however I also modified the default configuration to show my network devices in the systool bar when connected as well as when disconnected.
