Wireless PCI adapter card very slow speed

[Fasiuddin]

Greetings Everyone,

 

Let me start with the specs of my PC:

 

CPU    Ryzen 1600

Mobo Gigabyte AORUS AX370 Gaming k5

Ram: Corsair Vengeance lpx 8gb DDR4 2400Mhz CL16

SSD: Samsung 860Evo 250gb

HDD: Seagate Barracuda 7200rpm 2TB

GPU: Gigabyte pascal gtx 1050ti (Single Fan)

PSU: Corsair CX550w

Case: Antec P8 (Tempered Glass)

Wifi PCI express card: TP link TL-WN881ND V2

Speakers: Logitech z120

Mouse: Dell MS116t

Keyboard: TVS Gold bharat

UPS: APC BX600

Wifi Router: TL-WR841N

Internet Plan: 15mbps

 

My PC is on ground floor and my wifi router is on First Floor. Distance between my PC and Wireless router is approx. 16feet (4.9 metres). The only interference between the Router and the PC is Slab between the floors.

 

My Laptop and My Smartphones both have consistent 13 to 15 mbps speed (tested on speedtest.net) both on First floor & Ground floor (Where my PC is).

 

Problem:  In my PC I get close to 0mbps speed (Even though I installed the latest Wifi adapter driver from the TP link website)

 

I think that it has something to do with the PCI card Antennas, because:

 

1. When the Antenna is fully screwed to the card I get Nil speed, but when I loosen the antenna (By unscrewing little bit) and run the speedtest, I get 2 results:

            i) Same 0mbps speed

            ii) 13 to 15mbps (This happens after great trial and error of making the antennas just rightly loose or by applying little downward pressure on it)

 

After accidentally moving the antenna, it malfunctions again and now if I adjust it to the same previous position, it doesnt regain its speed rather, I have to trial & error adjust the antenna again in differerent positions

 

2. I inserted the PCI card on other slot and the results were the same.

 

 

So anybody knows the fix for the antenna problem or some advice, Please comment.

 

Thank you in advance

Seems like a faulty antenna or antenna connector. I'd RMA it.

Do you have another card to test?

I don't have another card, but I have tested with my Smartphone as well as Laptop and they both get speeds of 13mbps

I also have tested this card both in Windows 10 and Windows 7 (Now I am on Win7) and the results are the same

I think thats the only resort left.

Although I might try some suggestions, If any.
