XPS 13 7390, slow upload speed - SOLVED
Hi all,
Brand new XPS 13 7390 and I was getting 80 Mbps download and 0.1 Mbps upload. My phone right next to it was getting 40 Mbps upload. Spent ages googling and trying loads of things with the wireless adapter settings and re-installing the latest Killer Control Center drivers to no avail. None of those things were a problem and the solution was simple in the end.
SOLUTION - Turn off the Prioritization Engine in the Killer Control Center.
Sure, I could stuff around and work out how to increase the QoS for ALL applications but honestly why they (Dell / Killer) use such a pessimistic QoS algorithm by default is beyond me.
Hope this helps someone else save a day or more of frustration.

Dell Partner GEM Program, Out of Warranty Support Options, BIS (Bureau of Indian Standards) certificate, Get a copy of your Dell invoiceCan you give me a hint how to do that?
The setting is disabled in the killer control center, also https://support.killernetworking.com/knowledge-base/slow-speeds-and-trouble-accessing-websites-with-advanced-stream-detect-enabled/ does not work.
Uploads are extremely slow on my XPS 9310 but do work with full speed with all my other devices. Also when I plug in an external USB Wifi adapter to the XPS, I get the full upload speed again.
I also cannot open certain web pages...and some are extremely slow, including the Dell website.
The Killer wifi stuff is mainly killing my wifi and doing nothing else...optimized to death...
-----------------------------
I found a solution to everyone who has the same issue.
- I've removed the driver in device manager for the wifi card to get the windows default
- Reboot device
- Open Killer Control Center
- Go to Settings
- Now I was able to disable the Prioritization Engine
Result:
- Full download speed
- Full upload speed
- 20% faster ping
- Websites open again without errors
- Websites open a lot faster
I seriously don't understand what that killer stuff is useful for...

!! THIS WORKS !!
I was getting desperate because nothing I tried worked (Windows upgrade, Windows downgrade, Killer driver upgrade/downgrade, 2.4 Ghz vs 5 Ghz, ...).
Then I had the same idea as you and removed the Killer network card completely (Windows Device Manager) while checking the "remove driver software" checkbox. And after a reboot, I finally see normal upload speeds again
So thanks for sharing your solution, I confirmed it independently
Wow, me too.
After pulling my hair out trying to figure out why my upload speed was 0.1Mbps I also found out that the solution was to disable the 'Kill optimisation engine', then found this thread as confirmation of what I had done.
Not a good experience.
Dear "drtimoneill",
You deserve a medal... days and weeks I was trying to solve the upload issue I have with my Dell XPS 9310, getting around 600mb download from my fiber network, and an awful 15mb upload.
Turning off the prioritization in the Killer Control Center did the trick, and I now have same speed on both up- and download.
Many many thanks !

Since drtimoneill is the 1st post, I cannot mark it as the Accepted Solution. But I can "replicate" what he did for all to see.
Please check my instructions below and tell me if I left anything out.
* Click the Windows icon
* Type killer
* Click Killer Control Center or Killer Network Manager
* Click Settings
- Turn Killer Prioritization Engine to Off
* Under System Settings
- Turn Advanced Stream Detect to Off
* Click Set Bandwidth Limits
- Set the Upload and Download speeds according to your paid for connection. Example, I pay SuddenLink for 500MB down. So I set both for 500MB
* Click Apply Changes and retest
