@DELL-Cares​ I actually did contact support, but they told me the problem was with my Dell Precision M7510 and told me to take it to a local repair shop.

The problem is NOT with my device, as I could also duplicate the issue on my Dell Precision M7520 when running Dell SupportAssist 4.10.1, disabling WiFi, and connecting to the internet via Ethernet.

So I uninstalled Dell SupportAssist 4.10.1 and, fortunately, had a backup copy of an older version of the software.  I installed Dell SupportAssist 4.8.2 on BOTH of my devices, and it worked absolutely flawlessly. 

So the issue is with SupportAssist 4.10.1, but I can't seem to convince Dell Support to look at it.

For now, I am going to use version 4.8.2 and will NOT click on the link in Dell SupportAssist to update the software to the latest version until I am assured that this issue is fixed.

I have this problem too on My Dell Precision 7520 on Windows 10Pro.

The Latest Support Assist Software is not working properly. It FALSELY states "We can't reach the internet right now. Let's get you back online"

and "Check For Updates" can not be selected by it's self & in Full System Scan it is unselected by default.It refuses to be selected so we can not get any Critical updates to BIOS etc.

You broke the app with the latest update. Fix it please or tell me how to get the previous one to this update?

@Master VB Guru​ I created a thread on the 7th with the exact same problem here

Btw, even with Ethernet it randomly works 10% of the time, but that's not saying much.

Could you tell me where do I get SupportAssist v4.8.2 so I can nuke v4.10.1?

Thank you.

You are correct on that.  I’ve had it fail recently even when BOTH WiFi and Ethernet are enabled.

When I download SupportAssist, I save each setup executable to a folder on my External USB Drive by Version Number…just for situations like this.

I have not found anywhere on Dell’s website where you can download an older version. 

same problem here , anyone found a way for resolve the issue or get old version back? thanks

@Master VB Guru​ Isn't the setup file just a wrapper for whatever version Dell's servers are pushing?

Is it possible for you to share your v4.8.2 setup somehow?

@ner0​ This is the SupportAssistInstaller.exe application that I used.  It installed Dell SupportAssist 4.8.2 for me.

When I ran the 4.10.1.42635 version downloaded from the website, it installed 4.10.1.

Here is a link to it on my Google Drive:

@Master VB Guru​ Awesome, that actually worked. Not for long, I'm sure, but it pulled v4.8.2 like you said. I'll just ignore the upgrade notice.

At some point I may even completely discard SupportAssist. I'm working on a powershell script to check latest BIOS version and download the setup file if it's newer. It's a bit primitive and will not work if/when Dell changes the URLs or HTML layout, but it's an alternative I'm really considering after this latest issue.

Fun fact about Dell's CDN:
When using Powershell (and probably other stuff like curl) to pull Dell's drivers webpages takes ~20 seconds, but if you impersonate a known bot like Google's then it is prioritized almost to the very top and only taking ~1 second to reply. That's a 95% increase in response time.

I guess I shouldn't have mentioned this publicly, but I have.
