First, let's look at the apartment used in our testing and how it is set up. The router is placed in the living room. With most wireless routers, the signal strength is not good in places like the Kitchen and the Medium balcony.
Our testing was done using a fast 1 Gigabit Internet connection capable of uploads on the internet of up to 500 Mbps.
To get a better idea of the performance offered by ASUS RT-AX82U, we compared it with ASUS RT-AX58U (one of our favorite Wi-Fi 6 routers) and TP-Link Archer AX6000 (a top-performing Wi-Fi 6 router from the competition).
We analyzed the 2.4 GHz band first, when using the Wi-Fi 4 standard, and we measured the signal strength with NetSpot. The signal strength offered by ASUS RT-AX82U was on the lower end of our comparison in all the rooms of the test apartment.
We used SpeedTest to measure the speed of the internet connection when connected to the 2.4 GHz band on Wi-Fi 4. The download speed offered by ASUS RT-AX82U was outmatched by ASUS RT-AX58U in all rooms. In one of the rooms, it was surprisingly low.
When we measured the upload speed on the 2.4 GHz band, the results we obtained were surprisingly low in some rooms.
We used the PassMark Performance test to transfer data between two computers connected to the network on the 2.4 GHz band, when using Wi-Fi 4. ASUS RT-AX82U was outmatched by the routers we compared it to, in all rooms except one.
When we measured the upload speed, the results we got were surprisingly low in most rooms, except for the one where the router was placed.
On the 2.4 GHz band, when using the Wi-Fi 4 standard, ASUS RT-AX82U delivers uneven performance, and the upload speed seems to be problematic. This problem should be investigated by ASUS and fixed in future firmware updates.
For the next set of measurements, we analyzed the performance of the 5GHz wireless band, using Wi-Fi 5. We looked at the evolution of the signal strength from room to room. Again, ASUS RT-AX82U did not manage to impress us.
We used SpeedTest to measure the speed of the internet connection when connected to the 5 GHz band, when using the Wi-Fi 5 standard. ASUS RT-AX82U was the fastest router in the rooms closest to it.
When we measured the upload speed with SpeedTest, ASUS RT-AX82U performed great in most rooms.
We then used the PassMark Performance test to transfer data between two computers connected to the network using Wi-Fi 5. ASUS RT-AX82U delivered excellent results in many rooms, managing to beat its competitors in several cases.
The upload speed was excellent everywhere. A surprising result, considering our previous measurements on the 2.4 GHz band.
ASUS RT-AX82U is a very good performer on the 5 GHz band, when using the Wi-Fi 5 standard. Data uploads were especially fast in our measurements.
We remained on the 5GHz wireless band, but we switched to using the Wi-Fi 6 standard. Unfortunately, the laptop we had when we reviewed previous Wi-Fi 6 routers was not compatible with this standard, so we cannot compare ASUS RT-AX82U with other routers. This model should, however, be featured in future reviews for routers that support Wi-Fi 6, so stay tuned. 🙂
We first used SpeedTest to see how fast the internet connection is when using Wi-Fi 6. You can see the results below.
Uploads were fast too, but in a few rooms, the maximum speed dropped quite a lot.
We then used the PassMark Performance test to transfer data between two computers connected to the network using Wi-Fi 6. In half of the apartment, ASUS RT-AX82U was an excellent performer, while in the other half it delivered speeds that were lower than expected.
When measuring data uploads, we noticed the same trend.
When using Wi-Fi 6, ASUS RT-AX82U is an excellent performer in rooms that are separated from the router by a maximum of one wall.
We measured the speed of the internet connection with a 1 Gbps Ethernet cable using SpeedTest. ASUS RT-AX82U delivered speeds that were very close to the maximum potential of our internet connection: 1 Gbps for the download and 500 Mbps for the upload.
Then, we ran a network transfer between two computers, using the PassMark Performance test. ASUS RT-AX82U got really close to the maximum speed possible of 1 Gbps.
ASUS RT-AX82U delivers real 1 Gbps Ethernet connections, as expected from a modern wireless router.
We connected a portable SSD to the USB 3.0 port of the router and made some data transfers on it. We measured a download speed of 749.50 Mbps and an upload speed of 354.02 Mbps. Most users are going to be happy with these numbers.
ASUS RT-AX82U has a fast USB 3.0 port that you can use to connect fast storage to the router.
ASUS RT-AX82U is a premium router with plenty of features, some of which are aimed at gamers:
- Gear Accelerator - prioritize the network traffic generated by gaming devices, such as your desktop PC or your console, to get the fastest speed possible and the most bandwidth.
- Mobile Game Mode - boosts online gaming performance on your smartphone.
- Open NAT - with the help of game profiles, you can easily set the network address translation rules for your favorite games.
