These are the steps I follow to fix issues with the Killer Intelligence Center {formerly Killer Control Center) [URL] This is from Intel's site, I follow all 3 steps in order, then restart. The article says windows store, but I get these Killer updates through windows update and it works for it also.  Whenever windows updates it again, I follow the same steps again. Be sure to look for Killer Intelligence Center, and not Killer Control Center because the name has changed.
HELP! I have spent countless hours of remote Technical Support when my out of warranty (1 year warranty expired January 2021) XPS 8930 ran into a wall at which time after a Killer Ethernet Driver Update, many things went wrong.    Tech support for about a month attempted to resolve the problem, finally did a reset saving my data. Still no resolution.  They told me it was a hardware issue, so I sent the device to them on Express $59.00 service. At this point when I sent it in, I could utilize most functions on my device with the Ethernet cord plugged in. I contacted Verizon Fios my internet provider and they told me it was my device. My Upload speeds with the Ethernet cable plugged in are less than 1 Mbps.  The last tech support agent conferred with the team and said it was probably the Internet Adapter (Plug) that needed to be replaced. They had my system from the 16th to the 28th when it was returned to me. Said they replaced the motherboard and some plastic components (no details). Still NO Upload speeds and cannot function with the cord plugged in, only on WIFI. So after spending yet another hour on the phone with a tech agent, he said I will probably have to send it in again.  They seem to be CLUELESS. I had seen this post prior and keep trying to get them to review the details. I am not TECH savvy and find it entirely too complicated. I need my device, I have several internet marketplaces that I run and need this nightmare to be put behind me. I have since purchased an HP laptop to function, but I need access to my Excel spreadsheets docx and my Adobe P/S Elements installed on my XPS 8930. Please any layman-term advise would be greatly appreciated. Thank you in advance.
