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 adapter for Non-Wifi Motherboards - Product meets expectations. I would recommend this adapter only for those who have Wi-Fi-6 routers/mesh routers to enjoy the high-speed internet. Easy to install the hardware but quite tricky to install drivers. Product come with Driver disc and its challenging for those who don't have DVD writer, but drivers are available on TP-link official site for quick installation. Impressed with hardware quality to manage heating issues.

### ⭐⭐⭐⭐⭐ A DETAILED DISCUSSION AND FACTS YOU NEED TO KNOW ABOUT TP-Link TG-3468 Gigabit PCI Express Network Adapter
*by A***N on 5 July 2017*

First of all I want to say is that the product is AWESOME. Secondly, the delivery was on time (actually it came before the expected delivery date).Go Go Amazon. Now lets come to the question, why I needed this? Well, recently a THUNDERSTORM hit our locality and my Desktop PC was affected by this lightning resulting LAN port malfunctioning in the CPU. My Wifi router malfunctioned too (I gave that to service center later). I called my ISP and they told me that my LAN port was fried and I had to buy a new one.So, I went to local shop and bought a USB-to-LAN adapter for Rs.350. It worked OK at first then I faced problems- my internet speed was limited to 750 Kbps (my ISP provides upto 12 Mbps), the internet connection was not stable, my PC lagged sometimes. So, I googled it and found compatibility issues saying "USB ports are not meant to act as LAN ports". Thus I went to the 'Mecca' of electronic components and parts of Kolkata, Chandni Chowk for PCI LAN card. Interestingly I couldn't find it there (searched for two consecutive days). So, after gathering some infos about my motherboard, PCI and PCI Express, 10/100/1000 Mbps I ordered TP-Link TG-3468 Gigabit PCI Express Network Adapter on Amazon for Rs.750. It came in a very nice packaging with 3 YEARS WARRANTY on the box. In the box there was this LAN card, Driver installation disk and User manual. I installed the card in my PCI Express slot, switched on the PC and BAAM!! There it is. I DIDN'T even HAVE TO INSTALL THE DRIVER SOFTWARE. My onboard Realtek PCIe GbE driver software was compatible with this device. I connected my ethernet RJ45 cable to it and the internet just works fine now as it was before. Now I get the expected internet speed as specified by my ISP, the network is stable and my Desktop PC is running fine as it is new. I am happy with this product. Now some things you need to know before you buy-- 1. This is a PCI EXPRESS LAN card. So check if your motherboard has PCI EXPRESS slot. It should be written as PCIEX4(in my case) or PCIEX16 (generally graphics card is installed in this slot) or PCIEX8 or PCIEX1 or PCIe. If it is written only PCI then this LAN card is not compatible. 2. It works on any PCI Express slot regardless of its version. 3. Don't panic about the fact that your motherboard's PCIEx slot is longer than the gold connectors in the LAN card (in the picture). The length of the slot doesn't matter. It just fits fine. 4. There are 3 LEDs indicating network speed. 10 Mbps LED, 100 Mbps LED and 1000 Mbps LED. According to your internet connection the LED will blink (100 Mbps LED in my case) 5. Comes with 3 Years Warranty. 6. Consult you Internet Service Provider (ISP) before buying. Hope this review helps everyone.
