it happened a few days ago when i got home from work.. my internet speed was so slow that its not even worth using. i have 2 computers hooked up to it and only 1 is very slow. i have used my smartphone as a hot spot and its fine when i do that. im stuck using wifi when i try to plug in my ethernet cable it wont use it to connect.. like it cant find it idk. i noticed an orange light when i plug it in idk if thats normal or not. i

i have tried to restore my computer a few times but it failed every time. i tried a few times from safe mode and now i have lost the older restore points.

i have dell xps 8300 running windows 7
zhone modem
linksys router

the other computer that works with with my internet is windows 10. so maybe it could be a problem with windows 7?

as far as ik nothing has changed idk what caused this problem

cable sounds like it went bad. change it. or better yet, try plugging in the cable from the fast PC to the slow PC and see if it's suddenly faster.

It could also be a bad port on the switch/router.

Go in to Device Manager and uninstall your network adapter. Reboot and let Windows "discover" the adapter and install the driver. If it doesn't you may need to download the driver on your other computer and and then reinstall it or you might be able to use the driver disk that came with your motherboard.

If you don't have a network card, try reinstalling the ethernet controller driver. Also right click on the controller and select Properties, Advanced, Speed and Duplex, and set it to 100 MB Full Duplex.

Not really, but the issue might be connected to interference at the 5 ghz frequency or even a problem with the router itself. You might try changing the router channel to a less connected one and see if things improve.
