Hey guys,

So this has been happening for quite sometime and I've come very close to throwing the laptop out of the window in rage. I have stalked countless forums and so far nothing has worked out. Mostly because I have no clue how DCHP or IPv4 and stuff works, so i'm going to explain it as basically as I can.

I have a Dell Inspiron 15R series laptop, with 8 g.b. ram and a decent enough graphics card. It's around 3 years old, started out on Windows 8 then upgraded to 8.1 and finally 10. The problem started a few months after I upgraded to Windows 10, so i don't know if it's related to that. Anyway, onward to the problem.

My ISP provided me with a static IP and DNS and gateway. I use a Netgear router without modem. The ethernet cable is directly attached to the WAN port of the router. Now the thing is that, when its connected (the ethernet) to the router, the IPv4 option is set to "obtain IP address automatically" on my ethernet properties. And When I connect the cable directly into my port, I have to put in the IP addresses and DNS and gateway myself to get the ping reply. For the last few months, out of nowhere, my speed starts to fall and sometimes come to a complete standstill, no page would load. On connecting the ethernet directly to my laptop and manually putting the IP addresses and everything, the ping reply would still come out as "request timed out". On going to cmd>ipconfig/all it was showing that my autoconfigured IPv4 address was a random 169.XXX.XXX.XXX and my actual ISP provided IP was set as duplicate. So I called my ISP to help out with this problem, they weren't much help except for "have you tried turning the router off and on again?" Which I did, multiple times. Keeping it off overnight seemed to have fixed the problem. When I checked the next day, my actual IP was set back to my actual one. And then it was fine for a few days and bam, same problem. So I called my ISP again, and they said it was something related to my laptop's hardware.

Then I hit the internet. A thousand searches and fixes later I am finally writing here as a last resort. I have tried everything, even though i have no clue what to do. Can someone please help me with this? I am a complete layman at this and do not understand how all of this works in detail.

Also, even if it is my laptop's hardware that's causing this, why is the internet not working properly on my other phones? just a question.

Any help would be appreciated.

Yeah, the Ethernet cable is directly connected to the WAN port of the router. It's a cable connection, as in there is no telephone line in the whole setup, my ISP just extended a cable and I just plugged it in my router.

I hope you understand what I meant
