Wireless Adapter Failing to Work on Dell 7020

You might also update the BIOS if you have not already:

Greetings Islug!

Thanks for your question. I will assist.

First, I have a few question.

1. I assume you’re running the minitower version of the 7020. Correct?

2. If you’re running the minitower, have you tried popping the D-Link card into the x4 slot instead of the x1 slot? You may have the same problem there. I just want to know if this has been tried or not yet. The x4 is show below, outlined in white. The D-Link site says  " You can connect the Wireless N 300 PCI Express Desktop Adapter to any PCIe slot in your computer, whether it is an x1, x4, x8, or x16 slot."

I have not tried this as yet. I will do this later today and let you know the results

Hi, 

Yes, you are right, it's the MT version. I inserted the cards in all the slots and tried it but it still gave the same screens after restarting the PC a few times.

Hi, 

I tried the update but it is still giving the same problems

Good morning Islug!

Thank you for your feedback and help with troubleshooting this.

Please send me a friend request which includes your name, email, company name and the service tag of an affected 7020. I have some information for you.

Hello,

What's the update with this case?

I've got the same problem with a D-Link DWA 121 USB WiFi Adapter.

I've updated the BIOS as well with no luck.

I've even got a D-Link DWA-525 PCI Adapter, which doesn't even get detected.

Hello,

I would also like to know if there has ever been a fix to this issue.

Currently experiencing this problem on multiple 7020s. All above scenarios have been tried.

hardware: Dell supplied wireless cards\dlink wireless cards.

Operating system :windows 7 x64 bit (sp1)

Thank you

Hello, has there been a solution for this issue?

I am experiencing this issue on multiple Dell 7020s.

Have tried with dell supplied wireless cards and dlink wireless cards.

Thank you,

Tony

The solution is to use Wireless AC USB adapters that cost less than $20 each.  The AC speed also requires a wave 2 dual band router like the netgear nighthawk.  You have to change both ends to get the faster speed.

The AC600 DUAL BAND EIDEMAX EW-7811UTC units are under $20 at my local walmart.  They work fine.  They are faster than wired network my fios is 100/100 meg and they get over 80 Meg both ways on speedtest.net.

Hello,

Thank you for the reply. Sadly the usb wifi adapter is not an option. These machines are accessed by the public and the usb adapters can/will disappear.

Are there issues with the 7020 Motherboards?
