Hi,
Will it harm my computer if I plug in a CAT5 cable (RJ-45 Jack)into my computer while it is running. If I plug in a one end of a cat5 (RJ-45 Jack)cable into my computer & leave the other end of the cable unplugged, Will the red cross disappear from my network adapters icon (in win2000, winxp or vista).
Best Regards,

First of all there is no problem to your system hardware and operating system with either leaving the RJ-45 cable plugged or unplugged. The cross mark on the network icon indicates that you network connection is disconnected or not available.
You can only vanish the cross by connecting the RJ-45 cable’s one end to your PC’s network port and other one to the Network switch or router that you are using to access your local network or internet.
If you are bothered very much about this cross you can disable it from appearing on your task bar by navigating Start -> Control panel ->Network Connections ->Select the Local Area Connection or other connection (dial-up) ->right click and go to properties -> Uncheck the ‘Show icon in notification area when connected’ and ‘Notify me when this connection has limited or no connectivity’ check boxes and click ok. After that restart your machine.
HI Micheal
No it wont harm your computer, The Cross thing in the Network icon means that you are not connected into a Network. As you mention above nothing will happen even if the other end of the cable is unplugged.
You can always hide the icon, But it wont remove that Redcross because its a basic notification when you are not connected in a network
Hope this helpÂ
Thanks
Hi Micheal,
If your network adapter icon has a red X or cross mark, it means it is disabled.
You have to open control panel, double click system, click the hardware tab, open device manager, right click on the selected network adapter/driver and hit enable.
Disconnecting the RJ-45, or its other term is Ethernet cord, is basically just depriving your computer from receiving internet access from an internet source. It is part of the physical set up of the system and will indicate a red X on your network connection icon at the right side of your system tray if its unplugged.
Hello,
Cat 5 is required for basic 10/100 functionality. It is not a good idea to keep your computer switched on and attach the cable, it is not risky still it is better to take precautionary measures. Moreover this won't help as well with the red cross and the cross will be still there.
Try checking your network connections by going in the network placed on your desktop and also consult your service provider at times the problem is directly related from there and we cannot figure it out. Hopefully you will resolve your issue by one of these methods.
Good Luck!
