I have been having problems for about 5 months now, my internet would just randomly disconnect and come back in minutes. It mainly happens when i would be upload something or load up a in a game, I went on a website for my internet speed and everything was fine but my upload speed, it was at 0. So I contacted my isp and they said everything was fine on there end for some reason the problem only happens on my computer. Not the laptops or phones that i have. I was on windows 10 pro but then downgraded to windows 7 and still the same problems occur. i got support by Microsoft but told me to contact dell support or Amd, i checked if all my drivers were all up to date using dells program to check for drivers on my computer and i got this.
This is not an AMD issue. AMD doesn't make drivers for LAN.
This could be a problem with your LAN circuit or card or modem on your Motherboard or LAN Driver issue or Windows issue.
I notice that at Dell under your computer support site : Support for Studio XPS 435 MT | Diagnostics | Dell US , Dell can check your PC hardware or check a particular part of your computer for you. Maybe you should allow Dell to make a full hardware diagnosis of your computer (about 40 minutes) and see what results come back.
If you like playing games I would definitely add another 4 gbytes of RAM MEMORY to your System as a minimum.
Cool...changed it..Thanks
