The difference between 82579LM and 82579V is 82579LM supports vPro, macsec, in terms of connectivity functionality should be the same.Power up in morning ) 82579v adapter shows Windows driver code 10 - with media disconnected status in ipconfig.Hard power off while machine running, wait 60 seconds and power on usually fix.Problem re-occurs if machine is shutdown and powered off for a few hours.
It is not cabling or router since problem is resolved by one of the above power cycle steps. Configuration: Motherboard: Asus P8Z77-V Pro Bios: Asus 2104 ( latest ) OS: Windows 10-x64 Network Driver: Intel 12.5.31.4 ProSet 21.1.30.0 Applied NVRam update ( 82579VSKU ) adapter is now 82579V - no longer bounces to LM. Tried: Older BIOS Microsoft Windows 10 Driver Problem appears similar to: message264820 264820 thread110194. Just wonder if you have tried using Asus driver as this is onboard NIC on theri system. Full power shutoff without shutdown and restart does resolve most of the time. I have read some where in the design specs for the 82579V PHY where it seem that there is a process whereby it switches from PCIe to SMBus when in power off state. There seem to be lots of threads around the net about bad behavior with 82579V PHY, but cant seem to find a solution the works reliably. Since there is no driver from Asus, this could be part of the problem as well. As this is an onboard NIC (Here is the information about onboard NIC support ) in which the controllers was supplied to Asus for integration on their system based on their specs. It is recommended to check with Asus directly if they can provide driver support and further check on the hardware aspect. Intel R 82579V Gigabit Network Connection Bluetooth Adapter WorkMy Wifi, Bluetooth adapter work but for some reason my 82579v suddenly stopped working. Its been like that for a couple of days and almost had it identify my network cable when setting it to 100MB Half Duplex mode. ![]() Im considering getting a USB to Ethernet adapter but Id like to avoid that. This cannot be too good for the disk drive - but dont have much choice. If machine if total powered off ( not shutdown just kill power ), wait 1 minute for power capacitors to drain, and then restarted - Network Interface seem to recover. This should have been resolved, the MB I have is a deluxe they still should be supporting this. Oh and my cat5e cable was broke because something ate throughout but regardless no other cables work. Please contact Asus to check if there are other user with the same board also experiences this issue. Can you provide more reference information about the design regarding PCIe to SMBus, so that we can further check.
