TP-Link AC1900 Archer A9 - Unboxing Test


TP Link Archer A9 Router Review:

Wired LAN Speed
We used Ookla’s to test the max speed the router can handle on our 1 Gigabit Internet connection. This is tested via a wired Ethernet cable. TP-Link Archer A9 can support as high as 941Mbps which is the maximum speed possible on Gigabit Ethernet connection.

WiFi Speed
We tested the WiFi speed of the TP Link Archer A9 by running speedtest with Ookla’s on our Macbook Pro with an AC1200 wireless receiver. Most devices in the market only support up to AC1200 receiver and AC1200 receivers will peak at about 600Mbps. We will be testing the speed at 2 distances from the wireless router. The far distance will be over 7 meters with a wall in between.

TP-Link Archer A9 features truly good WiFi speed on the 5Ghz band. We are getting way more than 600Mbps on the close distance test. When it comes to longer distances, it is still receiving a really impressive 482Mbps. Do figure that this is from a router less than RM500.

We can see the combination of newer hardware and the inclusion of Beamforming actually make a difference in performance. The TP Link Archer A9 router is definitely an A+ for the 5Ghz performance in this range. The WiFi coverage is slightly stronger than the TP-Link Archer A7 also.

TP Link Archer A9 AC1900 Wireless MU-MIMO Router

TP-Link Archer A9 is a great WiFi router with good performance and decent WiFi coverage. We highly recommend this router to those finding an affordable WiFi router that performs decently. TP Link Archer A9 is our favorite mid-range wireless router currently thanks to its affordable price point and good performance.

    I have typically changed ISPs every year or two when they jack up the introductory rates. Each time it is necessary to change passwords on every wireless device and set up a new router with port forwarding, DDNS, etc. The last straw was when I was recently denied access to my ISP’s router settings because of their “maintenance”. So I decided to get my own router to end that nuisance and meddling. I don’t need more speed than required for 2-3 HD video streams, so at less than $100, the TP-Link AC1900 Archer A9 seemed attractive.

    So in a week the router has been configured without problems for about 5 wired (with an ethernet switch) and 5 wireless devices, including two slingboxes and an industrial temperature monitoring computer requiring static routing and port forwarding with DDNS service. (TP-Link provides its own free dynamic DNS service or for use of NO-IP or DynDNS.) There is a downloadable 112 page user manual with live indexing that seems easy to use, although I’ve barely touched on topics like VPN and remote management. I do not even know what MIMO may be useful for yet.
    I have confirmed that the router’s WPS button works for easily connecting my wireless printer; and that it also turns the wireless signal off/on if it is pressed more than momentarily.

    The router’s 2.4 GB wireless signal is more than adequate for my house and yard. My Dell laptop speed tests at 20-25 mbps max up/down in most places up to 25 feet away in the house and 50 feet away in the yard when the signal is set to “medium” strength. At 100 feet from the house the signal dropped to about 3 down, 6 up or 12 down, 12 up depending on laptop orientation. On “high” strength the poor orientation values doubled. Similar low speed tests and laptop orientation effects were noted in a bathroom separated from the router by twelve feet and six one inch thick plaster wall layers. In no case would I expect problems streaming a video.

    My hardwired computer speed tests at 200 Mbps down, 35 up, which is what my ISP provides, so I cannot comment on higher speed results. Nor have I needed any tech support. The router does all that I require, is reasonably priced and has the unexpected bonus of its own free DDNS service.
