This is an HP Pavilion desktop computer with onboard wifi and wired network. It is about a year old and running Windows 10 Home. The user has been using wireless. Several months ago they noticed that when this computer started up, every other device on the network, mobile devices included, came to a crawl. Speed test confirms the speed when the computer is shut down is 16Mbps... the max for their plan. When the computer starts up and joins network everything immediately drops to about 100 Kbps... almost non-existent. The computer in question gets the full speed so it is the only computer on the network that works.
I tried disabling wireless and using Ethernet only and the issue is the same. I tried disabling Ethernet and using wireless and it is still the same. So, same regardless of which adapter I use. Checked config... DHCP, does not appear to be IP conflict. User called in ISP and they have done some troubleshooting and replaced the router/modem... no difference. I looked at network performance via task manager and did not see anything hogging (did not run any networking tools though). I brought the computer out of that environment and into my shop and guess what... everything works fine. I was unable to reproduce the problem outside that environment which eliminates hardware and OS corruption of some kind.
Anyone have any suggestions as to what might be causing this? I did read a post somewhere where a guy said a faulty monitor was causing network issues? Might this be it (I guess I can test this when I return for more troubleshooting next week). What else might cause this? Thanks
