I've recently shifted to 5G and was wondering if I should get an AC1900 or AC1200 router for the best speed.
My current adapter, TL-WN722N is years old and its giving my abysmal speed.
Also does anyone have a good recommendation for a 5G wireless adapter?
Thanks!
The latest technology to use is AC6600 chipset, it gives you not two bandwidth but three bandwidth for transmitting the wifi signals. TP Link Deco X90 , Asus AX6600 etc, these wifi routers could covering your house at average download speed around 800Mbps -900Mbps in 5GHz without interference of others if your internet plan supports to 1000Mbps.
By Telstra 5G, do you mean going to tether off Telstra 5G Mobile Broadband network?
Wifi wise, it depends what will be on your wifi network.
TP Link AC1900
* 5 GHz: 1300 Mbps (802.11ac, 3×3, 80MHz)
* 2.4 GHz: 600 Mbps (802.11n, ?, ?MHz)
TP Link AC1200
* 5 GHz: 867 Mbps (802.11ac, 2×2, 80MHz)
* 2.4 GHz: 300 Mbps (802.11n, 2×2, 40MHz)
3×3 means 3 spatial streams.
2×2 means 2 spatial streams.
What this mean is if your client device (e.g. your laptop, mobile phone on wifi) doesn't use 3 spatial streams, you get same max speed on AC1900 as AC1200 using a 5GHz wifi network.
As an example, iPhone 13 supports upto 2 spatial streams. You won't get benefits using AC1900. In this case you are better off getting AX1500 router, which gives you max speed of 1200Mbps (802.11ax, 2×2, 80MHz) on 5GHz wifi network.
TL-WN722N uses the 2.4GHz wifi network. Your abysmal speed probably due to network congestion in your vicinity (apartment setting?). Once you configure your wifi on the 5GHz, I suggest get a TP-Link Archer T3U AC1300, basically a Dual-Band adapter that supports 867Mbps on 5GHz.
