My wife has an HP all-in-one 21-2024 that came with Windows 8.1. I upgraded the OS to Windows 10 a few weeks after the release date.
My wife has been complaining about how slow her Internet connection is for years and across many different pc's so I didn't pay too much attention until I was installing Office 365. That got me to go to speedof.me and run the test. We are on a 35Mbps plan with our provider. My desktop, my laptop, my phone, and several other devices in the house all get 25 to 30 mbps where as my wife's HP usually gets about 10 and absolutely will not download any faster than 15 according to speedof.me and speedtest.net.
Even though every other device in the network gets expected speeds I tried several different physical network configurations as well as changing up the settings in the router. All of this led to me running a cat 6 cable directly from the modem to the problem machine, disabling all unnecessary programs and services, updating the Ethernet driver first from HP then directly from the manufacturer. All of this and still no results.
The only thing I haven't done is trying to transfer a large file from another system in the lan to the HP. I'll hopefully get a chance to try that out this weekend.
Does anyone have any suggestions for what I can try if the lan transfer doesn't indicate an issue with the hardware?
