## Description

From the manufacturer

Review: Plug, Play, Perfect WiFi - I purchased the TP-Link TL-WN781ND PCIe card for a compact PC build, and it delivered exactly what I needed. The package includes two PCIe bracket plates, standard and low profile. Since my case required the low-profile bracket, I swapped it out easily using just two screws. The build quality is solid, and the antenna feels sturdy with smooth 360° rotation. It doesn’t look or feel cheap. Although the box includes a driver installation CD, I didn’t need it, Windows 10 automatically detected the device upon boot. No setup hassles at all. I ran a few basic network speed tests and the card held up well with stable signal reception and consistent performance. Overall, it’s a great budget-friendly option for adding wireless connectivity to a desktop. Simple install, good signal, and no driver drama.
Review: Best and No.1 wifi adapter under 700rs with excellent operation - This is best Wifi Adapter you can get under 700rupees its catching range is so high for instance i have installed my router in ground floor and even on 2nd floor its catching full speeds good for basic Surfing and downloading overall recommended by me for casual user. Installation is plug and play better than usb adapter

### ⭐⭐⭐⭐⭐ Good for browsing, office work & light gaming
*by P***R on 2 September 2020*

Installation of TP-Link TL-WN781 was easy on my AMD Phenom running win 8.1 which is nearly 10 years old. The driver installation took a long time but the signal strength is good on 2.4 GHz bandwidth. Fits perfectly in the small pcie slot without disturbing your pcie express graphics card slot There is no 5 Ghz band available. The speed is good enough although it's not blazingly fast. I am getting 50 to 70 Mbps speed on my Jiofiber WiFi although it's full speed is 100 Mbps & the wi-fi router is placed in the same room. Overall, a compact, basic wi-fi receiver with a small antenna that does its job efficiently for its price (I got it for Rs. 609 during the sale). I would definitely recommend it for daily use.
