Consider this thread as closed. I found the culprit: Google Chrome When I run the same test in Safari, the speeds are on par with every other device on my home network. Not clear what Chrome's issue is, but I found a number of others who have reported the same issue. So in review, this has *ZERO* to do with kext files or network adapter settings.

Yeah, I had kicked around the manual settings before now, to no benefit. Worth noting that when I boot from a Linux Live disc, speeds within that environment are normal. That, at least, clears any hardware considerations (cabling, router/modem, etc.) I may just carve out some time to revert to a previous edition.

The kexts used to date work, in terms of the Ethernet port being detected and usable. It just remains peculiar that the speed throughput is so minimal, as compared to other devices on the same network.

BCM5722D, from the E5530 High Sierra bootpack linked from Jake’s install guide, is what I tried first. I also tried the chris1111 version of it from GitHub.

Currently running the latest Mojave build on my E5530. It is hardwired to my router. However, when running a Speedtest, I do not even get to 100MBps. A Windows 10 laptop on the same network gets close to the 1Gbps of my Internet plan. The same applies to even my wireless devices. Speed was not an issue when I was running High Sierra before now. Is this a known issue?

Is there a way to toggle settings to supply the "Prevent computer from sleeping automatically when the display is off" selection if it is not displaying already? kext to install?

Perhaps. At the same time, this same hardware didn’t do this before High Sierra. Other devices like PS4 and Apple TV don’t have this behavior on the same TV either. I wonder if there’s a kext to introduce to the system that will show the option that Jake called out that I don’t have to toggle at this time.

Unfortunately I do not have this option to toggle.

Greetings All, I made the leap to High Sierra on my E5530 recently, with the steps outlined at: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-xps-clover-guide/ I had used the same guide to install El Capitan and Sierra before this. I keep this laptop connected to our big screen TV via a HDMI cable. An issue has come to light with High Sierra that did not occur with the previous MacOS releases. With the laptop's lid closed (which is typically the state I have it), the TV will show the desktop display just fine. However, if I change the TV off of the HDMI input that the laptop is using (i.e. by selecting another HDMI input, or cable input), the laptop immediately goes to sleep mode. Anyone also come upon this and stumble upon a resolution that will allow the laptop to remain awake while connected via HDMI to a TV that is not tuned to that HDMI input?

Thanks Bronxteck & black.dragon74! I found success with a different approach altogether. Credit goes to Alex / Schiller from this thread: https://osxlatitude.com/index.php?/topic/9414-azurewave-broadcom-bcm94352hmbbcm94352-wlanbt40-macos-sierra-10121/ My approach taken from there was as follows: 1) Clean-install High Sierra (ref: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-el-capitan-clover-guide) 2) Drop the 3 kexts from BCM94352HCMB -BT Sierra 10.12.1.zip (linked in the Alex / Schiller thread in post #1) to /System/Library/Extensions 3) Rebuild cache using the commands from Post-Installation Step #8 from the install guide I used above in the first step to clean-install) 4) Copy the two kexts mentioned in post #5's step 1 from the Alex / Schiller thread to /EFI/CLOVER/kexts/10.13/ 5) Use Clover Configurator to make the tweaks to config.plist that are listed in post #5's step 4 from the Alex / Schiller thread. 6) Reboot For me, both WiFi and Bluetooth were available. I was immediately able to pair my BT devices.

Brief follow up to where I had left off with Bronxteck's injector. I was able to pair an Apple Keyboard and Magic Mouse 2 successfully. However, the unit dropped to Sleep Mode after I had to step away for a bit. When I woke it, the devices were unable to reconnect. I shutdown/restarted, and this continued to be the case. I manually removed the entries for the keyboard and mouse, rebooted, and attempted to pair them again from scratch but could not. At one point, when scanning for BT devices, the unit saw the mouse again but was unable to pair it.

I moved Bronxteck's file to EFI/Clover/kexts/Other, rebooted, and Bluetooth functionality looks to be up and running!

Tried Bronxteck's injector by copying to /S/L/E and rebuilding cache, shutting down, and then cold-booting. Bluetooth hardware remains undetected.

I tried black.dragon74's approach from the 2017-10-29 update of the first post of this thread, but it didn't work out for me. I am using a DW1550 / BCM94352HMB dual-card. Wi-Fi is working just fine, though. I'll be on standby if anyone would like for me to try out anything different and can report results back accordingly. Currently running High Sierra 13.1 on a E7440. Same card worked fine when just running Sierra.

Thanks go to Jake Lo and the team for efforts with getting Sierra to install on my E5520 from this thread: https://osxlatitude.com/index.php?/topic/9911-fixed-help-to-install-sierra-on-e5520-with-legacy-clover/ However, in the time since, I have had a couple of issues. I'd be curious to learn if there are any easy tweaks to make to omit them. 1) On occasion, the graphics display on a window will have a line that goes through it horizontally. The fix is to quit/relaunch the app. 2) When unattended, the system will become unresponsive. I had run the series of commands to disable hibernation at the time of installation. Originally I was allowing display to turn off when the computer was unattended for about 15 minutes. I turned that off altogether, and today found that it was unresponsive to input when the screensaver had started to run (which froze in place at some point). 3) The integrated web cam is detected and works, but it just looks very blurry when used with something like FaceTime. Using it with Parallels running Windows looks just fine. 4) The internal microphone was not detected at the time of installation. So without that, Siri can't be used among other things. If anyone has come upon any of these issues and have been able to conquer them, I'd love to hear about your experiences!
