Optiplex 9020: Upgrade PCIE Wifi Cart to 6: some questions

Post by thomasreed »

I'm thinking about upgrading my Dell Optiplex 9020 from its current WIFI 2gb to a new 2gb/5gb/6GB PCIE card. Here's my questions:

The small PCIE card I'm considering does not have jacks to attach external antennas. There are two suspicious solder blobs on the board, which I guess are the antenna inputs. I don't believe the card can work without an external antenna. See the attached picture.


Second, these supposedly require a connection to the motherboard's internal USB port to connect to the computer's audio for Bluetooth. Does anyone know if the Optiplex 9020 has the 9-pin USB connector that other mobo's have? I know there are splitters for these 9-pin connectors.

Here are the abbreviated stats for my PC, including the current limited Wifi 2.4 card. Which works "almost" okay, except for unexpected drops which require me to turn off Wiifi and turn it back on. Thanks for any advice you can offer,
