ALFA Network AC1900 Wifi adapter - 1900 Mbps 802. 11ac Long-Range Dual Band USB 3. 0 Wi-Fi Network Adapter w/4x 5dBi External Dual-Band Antennas

I would highly recommend this because it supports both 2.4 GHz and 5 GHz bandwidth. Easy to install drivers in Kali 2020.2 and also supports packet capture and injection. The signal strength in this device is a little weak but you can upgrade antennas for better signals.To install drivers in kali:-- sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade- sudo apt install realtek-rtl88xxau-dkms- sudo reboot

This adapter has RTL8814AU chipset which is not officially supported by Kali for monitor mode and packet injection but still these features works using this adapter in Kali without any issues.I had to clean install my Kali for the drivers to work so if you're having issues with the drivers just reinstall your Kali.After fresh install just use these commands;1. apt update && apt upgrade -y && apt dist-upgrade2. apt install realtek-rtl88xxau-dkmsAnd for enabling monitor mode go for the manual methodIt certainly has better reception range when using as a normal adapter which is a plus point.

Advantages1.Long range2.can change antenna3.plug and play4.support packet injection and monitor mode in both 2.4 and 5 GHz bandDisadvantages1.cant use as a range extender

Bought this product from Amazon. This is a good WiFi adapter, there are two things that you need to know before buying.1. The warranty provided is not proper, when i wanted to check the warranty of the product i was redirected to some email ID and contact numbers from Amazon. When i tried to contact them it was informed that their number was wrongly given and they are not dispatching their products via amazon. I had written email to alfanetwork team of India but no response and i had to use. What i am trying to clear is that there was no proper warranty clarification provided by Amazon and the contact provided also was not of the person who sold this product.2. Installing this product is not at all an easy task, i had reinstall my Kali VM several times and install appropriate drivers for the adapter repeatedly. But don't give up, google searches will help you and you need to check websites by yourself if you want to use this device

No matter what you read online. No matter what you install, it will not SUPPORT PACKET INJECTION.It is a known problem within the kali community that the Realtek 8814 au will not be supporting packet injection.It is utterly useless. Will only work as a WiFi adapter for home use.I REPEAT, DO NOT BUY THIS FOR PACKET INJECTION. IT WILL BE RECOGNISED IN KALI BUT ONLY AS AN ADAPTER. IT WILL EVEN ENABLE MONITOR MODE.BUT THE PACKET INJECTION WILL NEVER EVER WORK.MESSAGE ME ON INSTA IF YOU HAVE ANY QUERIES. I WILL CLEAR THEM BUT DON'T EVEN TRY BUYING THIS.THANKING YOUCOOL_ABHI89

I had hard time installing drivers. but it work for me with kali linux 2020, linux mint, apple macbook air, kali linux on virtual box.

Performance is good

1) It's range is awesome when you use it in an open area and if you are working in a room then the power decreases.2) Lightweight and can be attached to the laptop's screen.3) It's not easy to use, you should have to be previous knowledge about wifi working to operate it and install its software (In Linux).4) For monitor mode you have to give the command Manually.5) Many software that uses the automatic command create a problem with this.Note:- if you want to buy a strong product and reliable. Please go with Alfa AWUS036ACH.
