RE: Optiplex 7010 SFF no POST when network adapter in PCI-E x4 slot
same problem: I had TP-Link TL-WN881ND installed in slot 4 and it worked fine.
the TL-WDN4800 does work in slots 1 and 2, but when it is in slot 4 PC won't POST.
updating BIOS to last version (A24) does not help. why this trap?
I have slots 1 and 2 blocked by graphic card so I sorted it out by buying PCI-Express PCI-E x1 Riser cable and leading PCI-E 2 around, but it looses some of adaptors signal strenght and the TL-WDN4800 hangs unprofesionally mounted down the case...
