Hi Rst29: Thank you for posting your system specifications. If you have the latest SupportAssist v3.10.4 it should be compatible with Win 11 (see the release notes <here>) but I haven't upgraded to Win 11 so I can't tell if any of the known issues for v3.10.4 driver scans are more prevalent with this newer OS.When you said all your drivers are up-to-date does that mean that you have a Realtek PCIe Ethernet Controller (network card) with the recommended v2.45.2020.0609 drivers currently listed on the support page <here> for the Vostro 3500? According to the "Important Information" section of the v2.45.2020.0609 release notes <here> the Realtek LAN driver version that is displayed in Device Manager should be v10.039.0212.2020 for both Win 10 and Win 11 after the update is applied.Did you try any of my troubleshooting suggestions (e.g., running the hardware test for your network card while connected to your router with an Ethernet cable)? I'm not sure what a WPE01-ELP error code means, but if you don't see an error code that starts with a 1000-xxxx or 2000-xxxx then perhaps WPE01-ELP is just a generic code warning you that the network card diagnostic can't finish until you have connected an Ethernet cable from your Ethernet (network card) port to your router. The solution for the 01-Sep-2021 thread 5490 AIO Support Assist Error WPE01-EC4 PCIE by Ricardo Eva states the following... "... I had a ticket with Technical support team for the same issue. The case was sent to their development team.Last week, I was informed that error code WPE01-XXXX is for analytical purpose only. A future SupportAssist build will take care of it. I was not given any ETA for the release though. As of now ignoring the message is the only option." ... so the display of your WPE01-ELP error code might simply be a bug in SupportAssist. You might find some additional information about this error code if you post your question in the PC-Doctor Ask Our Experts board at [URL] I searched that board for "WPE01-ELP" and couldn't find an exact match but there are a few threads there asking about similar error codes like Error WPE01-J9E - PCI Express Status Test . The PC-Doctor support rep who responded in that thread noted that "A failure of the PCI Express Status Test does not immediately mean that there is a problem with the associated device, but does indicate some sort of miscommunication."  Again, that "miscommunication" could mean that you didn't have an Ethernet cable connecting your Ethernet (network card) port to your router when you ran your hardware diagnostic or aren't using the recommended network card driver.-----------64-bit Win 10 Pro v21H2 build 19044.1466 * Firefox v96.0.2 * Microsoft Defender v.4.18.2111.5-1.1.18800.4 * Malwarebytes Premium v4.5.2.157-1.0.1562 * Dell SupportAssist v3.10.4.18 * Dell Update for Windows 10 Universal v4.4.0Dell Inspiron 15 5584, Intel i5-8265U CPU, 8 GB RAM, 256 GB Toshiba KBG40ZNS256G NVMe SSD, Intel UHD Graphics 620
When I use SA for scanning Hardware, I see this message. When I open errors I see the following: Network Card - Failed Error Code List PCI Express Status Test - WPE01-ELP   Question: What is wrong with my notebook? Thanks.
