Just as the title suggests, my machine refuses to POST when I install a tp link TL-WDN4800 wireless apapter on the "wire x4" PCI-E slot (the bottom one according to the manual). If I install the adapter in the top slot, everything works fine.
Can anybody help?
more details: The machine doesn't make any beep sounds when trying to boot, and no video comes up. Can only restart by holding power button down for some seconds....
There is no dedicated graphics adapter in the #17 slot 1. I intend on getting one, so this is why I would like my wifi adapter to work in the x4 PCIe slot.
It appears that not having the PCIe x16 video card installed is making the system think the wifi card in the x4 slot is video. Other users will have to test the 7010 with only an x4 card installed to verify this.
I just received my graphics card (HD 7750).
I proceeded to install the graphics card in the x16 top slot and the WLAN card in the x4 slot (bottom). The system shows the same behaviour as before, it won't boot.
If I switch the cards around, everything works fine.
This is obviously not working as intended, since my graphics card is now crippled to a PCI-E 2.0 x4 slot ....
I have the same problem, can you reply to DAN0512 ?
I have a wifi card, TP-Link TL-WDN4800, in the brown slot (pcie x4) and my optiplex don't boot.
If I put it in the blue slot (pcie x16), all is ok.
I need to install 2 cards, wifi (in x4 slot) and graphic (in x16 slot) ...
I thought it was possible ...
I recently purchased a TL-WDN4800 and tried to install it in my Optiplex 7010 mid tower, with the same issues described above. No POST, monitor does not turn on, HDD light blinks once and then stays off while fans spin.
I found that the card works in SLOT1, the blue one which I normally use for my graphics card, and SLOT2, an x1 slot that is normally covered by my graphics card's heatsink. SLOT4, the PCIe "wire x4" slot, does not work.
The card worked just fine in the x4 slot of a Precision 390 I had, so it suggests that the card is alright. But I find it a mighty coincidence that searching for "Optiplex 7010 Slot 4 no POST" only brings up this thread with people having the exact same hardware.
I'm going to try playing around with my BIOS settings to see if that straightens this out, but I'm here to say that this problem isn't isolated, and if anybody's figured out a solution in the past three years, I'd like to know how you fixed it.

Version of BIOS? The latest is A21 which was released last month (Feb, 2016). You should be able to flash directly to A21.
Make sure PXE boot is disabled in BIOS (assuming that option is available).

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...
