Ever since I got my Inspiron 5400 AIO 6 months ago, the diagnostic test in SA (SupportAssist) gives out the error code relating to "network card failed". This relates apparently to Realtek and is regarded, I understand as a false positive. In fact, in a 2018 post this seems to have been recognised by Dell and an update to the diagnostic was put in place apparently.

I got fed up with the messge so contacted support which seemed to be a robot and took a long time to navigate. I eventually was asked to do a Dell diagnostic by powering down my machine, then starting up and pressing F12. I followed instructions, did the diagnostic and all the tests were passed successfully. I passed on the validation code which confirmed that the Inspiron 5400 AIO was fine. No hardware or software faults.

So my question is this. Dell must be aware of this problem with SA surely. There are enough posts from concerned customers about this apparent "network card failure". So how about correcting this anomoly in SA? Frightening customers with a false positive is simply not good enough. Many thanks. Other than that, I'm very happy with my Inspiron 5400 AIO.
