NETWORK ADAPTER damaged

[rakib117]

My LAN port is not working.After PC power on, it shows the red LED constantly even without putting any cable.Computer shows nothing in "change adapter setting".Device manager panel shows no network adapter.
Before these happening i was trying to use NETCUT and I have changed my MAC ID a several times using it.And another incident was Storm.My computer was closed,i have a UPS,but LAN cable was in the port when there was thunderstorm outside.
I don't know what is the exact cause which damaged my LAN port.Is there any LAN card which is good as motherboard LAN port (and it's cost).If anyone know please kindly inform me

When LAN ports go offline our won't function due to a short or overload condition, often times you can bring them back by clearing the cmos on the board, though you will need to reset the bios settings to what they were before hand.

Sometimes just shutting down the machine, unplugging the power and pushing the start button to clear all power from the board will fix it.

Thank you for your reply chev65.When I got trouble I opened casing and took off Cmos battery for 3 minutes but this couldn't help.I also reset Bios & Cmos settings to its optimised default but this also disappointed me.Thank you again.

I have no knowledge of Netcut, allows MAC ID fraud? Interesting....

IN any case so your ethernet port is shot, happens, A LOT!
Didn't notice if that's a desktop PC or laptop.

If laptop, a USB Ethernet adaptor, if desktop you want a PCI Ethernet card probably. (can go PCI Express if you have the slot)

Sample items:
USB Ethernet adaptor
Newegg.com - Cables To Go 39998 7.5in USB 2.0 Fast Ethernet Adapter Cable

PCI Ethernet card
Rosewill RC-404 Ethernet Card 10/ 100/ 1000Mbps PCI 1 x RJ45 - Newegg.com


Not costly as those samples show, although where you are, have no idea.
