To generally describe the TP-LINK AC1900 Archer C9 Smart wireless Router, it is a good and quick router considering its short-range wireless speed as well as its nice features. Talking about its design, it is actually a great one and would totally look nice anywhere you put it. Even its blue led lights are very discreet.  Our tests can prove that it is definitely a router you can totally rely on.

It has some small imperfections though but we still think it is a great choice for its price. So, if you are looking for a new router, we highly recommend it.

To make you conscious of what you are going to be faced with, the most noticeable imperfection you will notice right away is its storage sharing; you can only access it via FTP and DLNA devices and not Windows Network. So, if that represents a priority to you, you should probably look for an alternative.


TP-Link is a brand that is mostly known for the good value for money it offers. Its products are generally low cost, mid-tier routers that are worth every penny. How do we know this? It is something that we can confirm with our experience using their products, as well as the many reviews on forums that say the same.

But now all we can say is TP-Link has increased its features such as performance and price bracket, and the Archer C9 Wireless router is a nice proof of that, considering its 802.11ac rating of AC1900.

And this is why we will not put the TP-LINK AC1900 Archer C9 Smart wireless Router in the range of mid-tier, run-of-the-mill routers, it is much more than that, and it offers the best features for its price. 

To help you out, we are going to point out the good and bad things about it so that you can make your decision.

Why you should buy it:

  • It has a great short-range wireless speed.
  • It is a router that is very easy to setup and use
  • It is from a reliable brand
  • It offers a great price for value.

Why you should not buy it:

  • You can find faster routers on the market (but for higher prices)
  • It has only one USB port (3.0)
  • It can only stand vertical (no possibility of mounting it on a wall or laying it flat)

Our TP-Link AC1900 Archer C9 Smart Wireless Router Review

First of all, we are going to talk about the price; The TP-Link AC1900 Archer C9 Smart Wireless Router is one of the cheapest AC1900 you will find on the market. 

It is the perfect router if you want to go up to 1300Mbit/s wireless speed of AC1900 without paying a fortune.

Our next best option is the Netgear R700, since it has extra features such as the USB support that makes you able to share hard drives and printers and Ethernet ports of four gigabit.

AC1900 Archer C9 Design and Features

Comparing to D-Link and Netgear who offer high end routers with angular designs reflecting a rather violent aspect, we prefer TP-Link designs because they usually keep it simpler and more modest especially with the AC1900 Archer C9.

It is a simple looking all-white router with a matte texture. It has a noticeable silver stand and three white aerials popping from its top. It is a design that is pretty similar to Apple hardware. So, if you are a fan of it, this one is the best router for you.

Simple usually means elegant, yes, but unfortunately it does not always mean practical. 

As we mentioned before, the router has a stand, which logically means that it can’t be mounted on a wall nor laid flat. Also, the stand is not really sturdy and will easily tip over.

But this remains as details, because let us be realistic, once you install a router, you usually don’t touch it anymore, sometimes not even notice it.

Let us move on to the aerials. Not only they are really easy to position, but they are also sturdy and you can remove them if you want.

The icons on the front have lights that turn on to indicate either power, Internet connection, Wi-Fi connection etc… Which makes them very easy to distinguish unlike the Netgear R7500 that has similar rectangular lights.

The back of the router is nothing special but it has the most important ports and inputs; we have the USB 2.0 port, WPS and reset button, four Ethernet ports, a power on/off button and a power input, which again you can easily distinguish since they are all labelled. 

On the side, we have a second USB port, but this one is a USB 3.0 port, mainly for sharing different files on your network using a USB drive, while the one on the back is a USB 2.0 port, used especially to connect printers.

What makes this router worthy its price is especially its wireless Wi-Fi capability that goes up to 1900Mbps. And like we said before it can be divided into two simultaneous connections of 2.4GHz 600Mbps/s and 5GHz 1300Mbps/s.

And even though you probably will not be using that feature a 100%, since you necessarily need a triple antenna hardware.

For example, you will ensure an AC1900 connection if it is with as another triple antenna Wi-Fi, which will able you to have a router to router setup.

Most phones and laptops are only dual-antenna, but there are still many advantages of using it with non-AC1900 devices.


AC1900 Archer C9 Setup

Outside the fundamental setup dialogue, the interface is easy and is a delight to use. The network map layout of icons within the basic view is admittedly useful and also the selection of options on the left is just about ideal. When you go browse through the advanced menu, the layout makes everything clear on where everything will be as everything is logically and cleanly organized. 

TP-Link doesn’t make a link between you PC app and Netgear Genie. Instead, the only software you should install is the USB printing tool (both Mac and PC versions are available). You need to run it only when you’re printing.

I am a huge fan of this approach as it keeps your mind in peace knowing that no software is running in the background. Also, if you want to access your router administer tool without logging into the web, there is an app that you can download on your phone (Android or iOS). Check video bellow for further details.

AC1900 Archer C9 Software

TP-Link doesn’t have a special name for its router configuration dashboard which is unlike Netgear or Linksys – however this doesn’t diminish its quality or make it less special. There are certain features that every good quality configuration dashboard has which are simplicity, tweak ability, and the interface layout. The TP-Link C9 hits a checkmark on every one of these boxes but it doesn’t brag about it.

Once you go into the software you realize how unassuming and uncomplicated it is. Features such as wireless settings, network mapping features, and parental controls are easy to search out, easily manageable, and excellent for any entry level technology used to get into it. There exists also numerous advanced settings which will allow you to dive into more technical features like QOS management, fixing a media server, and configuring access ports for the wireless printer. 

The TP-Link “Tether” app has made a change with a clean, easy-to-understand interface and more detailed customization options if you’re logging in while you are away. It’s not intuitive to use it over a laptop or desktop from home, but it’s still a good option if you’re travelling and need to watch the parental controls whilst you’re away. 

AC1900 Archer C9 Speed & Distance Tests

The TP-Link Archer C9 is at a value point where you don’t have high expectations, and a router’s performance doesn’t really need to be perfect (given the amount of time you spent on it). You use it with the intention in mind saying that it “ought to be useful for streaming and gaming, and that is sufficient for me”, without no prior high expectations.

In view of this, you can envision our reaction when the new speeds stated below starting running. 

On the 2.4GHz, network functions at a distance of 5ft, we had the option to maximize what the frequency can transmit (to say the very least): with a speed of 64.97Mbs download, and 96.35Mbps upload. The performance of the 2.4GHz started decreasing at 30ft, however just for uploads. When we moved outside, the download speed increased to 67.18Mbps, however the upload speed dropped by about 2/3’s, to only 34.26Mbps up.

On the other hand the 5GHz results were incredible. We tested it from a distance of 5ft and the Archer C9 performed at a staggering speed of 289.97Mbps download, 483.37Mbps upload. We were a bit surprised that the 5GHz had a download speed faster than the wired connection, putting away all our expectations and the competition’s hopes at the same time.

Similar to the 2.4GHz tests, the performance speed lowered at a distance of 30ft, however the difference wasn’t quickly noticeable. At 30ft, the C9 set a download speed of 181.40Mbps and an upload speed of132.40Mbps.

As we switched over to the 5GHz, an increase in the speed performance was noticed immediately. Once more, at a distance of 5ft, our Nighthawk X6 review indicated a download speed of almost 210Mbps, with an upload speed of 280Mbps. At a distance of 30ft, the speed decreased to 170Mbps download/169Mbps upload, but that’s something to expect as the 5GHz performance is impacted with signal loss when transmitting through hard surfaces like walls and doors.

The C9 even defeated its nearest rivalry, the Netgear Nighthax X6, on the wired performance front.

When connected directly to the source, the C9 exhibited a stunning speed of 556.59Mbps download/416.66Mbps. Similarly to the X6, this is still incomparable to the 990Mbps download/897Mbps upload we get when connected directly to the fiber modem. However, we have to keep in mind that price is cheaper and the speed is faster than the competitions’ products.

AC1900 Archer C9 Performance

The Archer C9 isn’t the perfect product when it comes to performance, however it still to a great extent satisfies its AC1900 billing. At its top performance, I measured a speed of 47.7MB/s, which is a little less than the 70MB/s of the fastest routers in the market.

However, the drop of speed due to distance is less than the faster routers. Here is a little example, the Netgear X4 R7500 drops from 81.3MB/s at 2m to 36.2MB/s at 5m, while the Archer C9 drops to just 35.1MB/s at 5m. At 10m (through two wall block) the R7500 performs the best, conveying 28.0MB/s while the Archer C9 can just oversee 14.3MB/s, however again that is a better average pace all in all.

Regardless, the Archer C9 is the slowest AC1900 router I’ve ever tried using the 5GHz band, it’s simply that most clients won’t complain about the deficiency. After all, it’s still fairly a better upgrade on most Wi-Fi N routers.

When it comes to 2.4GHz the coverage is much tighter. The speed at 2m is measured at 17.1MB/s while the fastest speed is measured at only 17.8MB/s. At 5m it’s 10.4MB/s contrasted with 14.0MB/s while at 10m the Archer C9 will get to a speed of 7.1MB/s while the fastest we’ve tried hits 8.1MB/s.

The USB performance is similar to it. The Archer C9 conveyed 23.46MB/s read and 13.31MB/s write from its USB 3.0 port. It’s less than the 60MB/s of some of the fastest routers but it’s relatively fast.


Thus, the Archer C9 cannot be a performance leader, yet it managed to remain unshakable when I used it as my primary router for a couple of weeks. That only exceeded my expectations of this product.

The TP-Link AC1900 Archer C9 Smart Wireless Router may appear somewhat strange when it sheds it bright light on your face from a standing position, however you’ll easily forget about that once you get to use this little powerful device. There are some improvement that we can make to the design of it and the software isn’t that astounding. Yet, for the money you pay for it with the performance, the Archer C9 is the best and affordable option. 

If you are looking for a high-spec, durable, and affordable router, the TP-Link Archer C9 is your best option on the market. It’s not the fastest but it’s easy to use and you can totally rely on it.

TP-Link AC1900 Archer C9 Smart Wireless Router Customer Reviews

“I purchased both the TP-Link AC1750 Archer C7 & AC1900 Archer C9. Both routers are excellent, but I decided on the C9. From my experience the distance on the C9 is better than the C7. The C7 did reach every area of my house and property but I found a stronger signal on both 2.4GHz & 5GHz signals with the C9 in the same areas. The 5GHz signal on the C9 also reached further. I am in a 4000sqft house and 1/2-acre property. The C9 router reaches every inch of my house and every acre of my property. Going through 4 walls and upstairs I get 3 bars of connection in my master bathroom. My previous set up of having 2 routers on each end of my house only yield 2 bars. At the furthest end of my property line I am getting 3 bars of connection where as my previous set up could not reach beyond my patio.

Set up is a breeze. Having the router for almost 1 month I have not had to reset at all. Initially my older laptop connected but could not get an internet signal. I had to make an adjustment to the laptop’s wireless card setting. So, if anyone is having a connection problem try the following -1. Got Network & Internet Settings2. Go to Change Adapter Options3. Find your wireless connection (can be wired connection too) and right click on it4. Click on Properties5. Look for Internet Protocol Version 4 (TCP/IPv4) and single click on it, this will highlight it and allow access to the Properties tab6. Click Properties tab and make sure both obtain an IP address automatically & Obtain DNS server address automatically are selected. My DNS server address property was not selected and was set to a particular address. Once I changed it to the automatically selection I was immediately connected and have not been disconnected. The C9 is the best router I have owned followed by the C7.” …. Read More

“Upgraded my 8.0.11n router. I took my time in setting it up and was up and running in all of 10 minutes. The web interface is easy to navigate and dig into the advanced features. It has a few things I may not use, but are very nice to know are there…usb ports for setting up a drive to share on the LAN, parental controls, ability to access files from the internet, ability to function as a media server (I already have my own set up, but this is nice), guest Wi-Fi, etc. etc. Really a well featured router, and the gigabit is nice!

Ran some speed tests before and after installing this router: laptop w/built-in wireless n: 52MBps -> 78MBps (and up to 118Mbps after installed an ace network adapter) desktop wired: 74Mbps -> 134 Mbps

My wireless range increased as well. Router is on the 2nd floor, and computers in the basement get a much better signal than with my previous router.”
