Hi Neti,
Is it your Ethernet or Wifi.
And what is it?
There are loads of preloaded drivers in W7.
Go to
Update driver > Browse > Let me pick > UNCHECK show compatible hardware. wait for listing to appear below.

Left hand column is for manufacturer scroll to yours.
Then in the right hand column scroll down to yours

Sounds to me like a hardware problem such as if the Ethernet for your PC is an add-on card ie. PCI then maybe it became dislodged, or if it's a motherboard GBe connection then that is a much more serious problem.

You said "send" as if the repair people were remote, but then "they bring" as if they might be local. I think you should contact them and suggest that it seems they broke your Ethernet when they fixed your graphics.
