D-Link DWA-131 wireless adapter not working properly very slow internet

So my computer used to be in a room with the router where i used the adapter to connect to the wifi and it used to work fine i would get 30-40mbps speed constantly but today i moved my computer to a floor above the router room.
There is a floor in between the router room and the computer room.Here i connected to the wifi network(good signal) and saw that my speed was extremely slow!!!!!!.I used my mobile in the same room and got good wifi speed 30-40mbps but in my computer i was getting 800kbps to 1mbps.I researched about this a lot here are some of the things i have already tried -
- Going to adapter properties then to Ipv4 and changing the dns to google dns
- Finding any other bandwidth controlling programs like Amd quickstream etc.
(found none)
- uninstalling adapter then restarting and installing.
- switching to older adapter version that was written on the product box.
- Setting the wifi connection to metered.
None of these worked.

Also i used portable hotspot from my mobile using my data and i was able to connect to it perfectly fine from my pc and surf the internet on the normal mobile data speed.(using this to write the thread)

My pc specs are -
Cpu - Ryzen 7 1700
GPU- GTX 1070
Ram - 8gb corsair ram x 2
HDD - 2tb seagate baracuda
SDD - samusung 250 gb

Please help me if u need any thing just ask me and i will get back to you as soon as possible.

A Wireless USB adapter ? Some of the adapters have low reception, and also the specs of the Adapter will help.

Is adaptor is causing problem? or Is it with changing the position of your system.
provide the adaptor specification.

Oopsie, missed the name in the Title

Thanks Joe !

Looks like the Range on the adapter is the issue, I've checked reviews apparently there is a drastic drop in performance when the distance is increased, this could be the reason for poor performance.

We can either get a better ranged adapter or use a Range extender in between to boost the signal.

Personally to be in the same room and get 30-40 Mbps wirlessly I don't consider very good depending on who your isp is, but then again how old is usb wifi card as they seldom last full strength beyond 2 years, you may just need a new one. If it is a desktop you have pci-e cards installed into towers I have always found get a much better signal and it occurs to me if you are under or over the modem, how difficult would it be to run a wire through the walls to get a wired connection or move the router to the room your pc is in is another alternative. I don't care what claims the router makers make wireless is almost always disappointing unless the router is really new or no more than 2 years old and better quality. I have never seen a router sold under $100 more than 2 years old worth owning anyway. And I also have never seen signal extenders at any price worth owning.
