Troubleshooting a wireles NIC
You can replace a wireless NIC in 5 minutes, Not so for a hardwired NIC.
In Desktop, Ethernet NIC is hardwired to the motherboard
If a problem with NIC in this system occurs, you have to replace motherboard because if a hardwired NIC is not working due to circuit issues it may spread to the rest of the motherboard in no time affecting the CPU and RAM and causing the server to shut down. Most companies would rather get a new motherboard
Before your could use a PCI card slot (only fits PCI slots) and can fix NIC by replacing with a PCI card slot. But now have to replace whole motherboard
