Comparison of USB WiFi Dongles & Deciding the best !

Mahfuz_SS_EHL

To All Network Experts, Which USB WiFi dongle will be good for better signal & MU-MIMO Supported Router in My Home ??

1. Chipset: RTL8811AU (1T1R) + 6 dBi Antenna (433 Mbps - AC)

2. Chipset: RTL8812BU (2T2R) + 2 dBi Antenna (867 Mbps - AC) + MU-MIMO

3. Chipset: MTK MT7612U (2T2R) + 2 x 3 dBi Antenna (867 Mbps - AC)

Note that, I need better Signal, the Router is assumed to be far from the connecting device & the router has MU-MIMO support over AC Network.

Thanks !

If your main os is linux,check here (type your chip):

Why not invest in a better router or a range extender or a mesh-WiFi system?

This is not a Laptop. For a Desktop system, we need this & unfortunately we can't use RJ45 Lab Cable ! Thanks !

Forget about USB WiFi dongles. Just find a decent PCIe based card, it'll save you the hassle.

Is it possible for a Adapter based on USB 2.0 transmitting 867 Mbps over AC (5 GHz) where theoretical data transfer rate for USB 2.0 is 480 Mbps at highest !

WiFi, unfortunately, has never marketed data throughput, only best case air rates. The 867Mbps comes from 100% duty cycle at the best data rate with all antennas, ignoring overhead of control and management and number of actual inputs and outputs of clients. That isn't actually how it operates and is very misleading. Then, there's TCP vs UDP traffic, where the maximum data rate is only achievable with unidirectional UDP traffic, which isn't real world traffic. Lastly, then there is the number of clients, where the more clients, the less aggregate bandwidth there is...

That's true. I suggested PCIe cards as the standard provides ample bandwidth, which generally reduces bottlenecking when you compare them to USB devices (think USB2.0 AC WiFi dongles).

Oh, PCIe is the way to go on any permanent install. Just not banging into it and damaging both the USB port and dongle alone is reason enough. Plus, of course the performance benefit.

just buy (qualcomm) atheros based pci (if you on desktop) and you good to go
