Radix AX6600 Wi-Fi 6 Router Review: MSI As a New Promising Home Wi-Fi Vendor

Share what you're reading!

If you have never heard of MSI, a.k.a Micro-Star International, it’s a Taipei-based tech hardware company focusing on motherboards and gaming PCs.

And that makes the Wi-Fi 6 RadiX AX6600 (model GRAX66) special. Together with the Wi-Fi 6E RadiX AXE6600 — the two were first announced during CES2022 and became available earlier this month — it signals MSI’s return to home networking, which its presumed compatriot rival, Asus, has lately dominated.

MSI was part of the game in the early days of Wi-Fi, but it left the market around 2008, during Wi-Fi 4.

And that’s exciting enough for me to take the new router out for a spin. Originally, I thought the Synology WRX560 would be my last Wi-Fi 6 router review.

Here’s the bottom line: As a Tri-band Wi-Fi 6 router, the RadiX AX6600 has nothing new — it’s a mundanely good standalone router with little to qualify as a “gaming router“. But looking beyond that, it represents MSI well as a new, viable, and potentially consumer-friendly home networking vendor. And that’s great news.

If you’re a fan of MSI, the new Radix AX6600 will fit it excellently among your existing gear, making it worth the reasonable $249.99 price tag. For others, it’s safe to consider it, but if you skip it for one of the more established brands in the related best lists below, you won’t miss out on much.

As you’re reading this, I’m wrapping up putting the Wi-Fi 6E RadiX AXE6600 through its paces and will publish a separate review soon. Preliminarily, the two are very similar, other than the Wi-Fi specs.

Updated: The review of the MSI GRAXE66 RadiX AXE6600 is now available.

MSI RadiX AXE6600 review: A cool and fresh Wi-Fi 6E router

MSI RadiX AX6600 Wi Fi 6 Tri Band Gaming Router 1 9
The MSI RadiX AX6600 has a traditional yet unique design.

Radix AX6600: Representing MSI as a new Wi-Fi alternative

Assuming MSI’s recent investment in Wi-Fi is for the long haul, the RadiX AX6600 has great potential. It represents a unique yet familiar approach to home networking.

Specifically, the RadiX AX6600 (as well as the RadiX AXE6600) uses a Linux-based firmware with a standard local web user interface. And this firmware will likely persist in future MSI routers.

MSI RadiX AX6600 Web User Interface
The MSI RadiX AX6600 has a robust local web user interface similar to many standard home Wi-Fi routers.

This approach means you will not be required to sign up for a login account to use it. Most importantly, if you’ve worked with a standard home router before, you’ll find an MSI router right at home.

What you can expect from an MSI router — the good and the bad

After over a week of checking MSI’s router firmware using the RadiX AX6600 (and RadiX AXE6600), I found it quite excellent, considering its new stage.

MSIwrt — if that’s indeed its name — is a robust, responsive operating system similar to Asuswrt though not as in-depth. But things likely will get better in future releases.

For now, below are the highlights reading what you can and cannot expect from MSI, no matter which router you end up getting.

Standard setup process

An MSI router shares the same setup process as any home router with a local web user interface. Specifically, here are the steps:

  1. Connect the router’s WAN port to your Internet terminal device.
  2. Connect a computer to its LAN port or the default Wi-Fi network printed on its underside.
  3. Open a browser and navigate to the router’s default IP, 192.168.10.1, or http://msirouter.login.
  4. Login with the default administrator account:
    • Username: admin
    • Password: varies — printed on the router’s underside.

And that’s it. You’ll be greeted with an initial wizard to finish the setup. Afterward, you can repeat step #3 whenever you want to manage the network.

It’s worth noting that the router will work immediately as you plug it in and turn it on using the default Wi-Fi information printed on its underside.

Since the admin and Wi-Fi passwords vary from one hardware unit to another, there’s no security risk if you use it like that. Still, setting it up properly is always recommended.

No universal backup restoration

MSI routers, including the RadiX AXE6600 and RadiX AX6600, don’t share the same setting backup file — you can’t back up one and load that on another.

While this is quite normal, for now, there’s no way to move between MSI routers without setting up the network from scratch.

Universal restoration is available in most Asus and Synology routers, making upgrading a network from an old router to a new one from the same vendor much faster.

MSI Router Mobile App
The MSI Router mobile app only works locally for now.

Simple local-only mobile app

Besides the local web user interface, there’s also the MSI Router mobile app (for iOS and Android) — similar to the Asus router — that enables users to manage the network via a phone.

Currently, the app only works locally and offers less in-depth access to the router’s settings and features than the web user interface.

Excellent Wi-Fi customization

Each MSI router comes with four SSIDs for each Wi-Fi band, including the main (default) one, a Guest network (disabled by default), and two virtual SSIDs in the “Multiple SSD” section (off by default.)

MSI RadiX AX6600 Wi Fi Setting Main SSIDMSI RadiX AX6600 Wi Fi Setting Multiple SSID
With deep customization, you can have a main SSID and two more virtual SSIDs for each Wi-Fi band.

Users can customize the main SSID of each band to the max, including picking the channel, channel width, Wi-Fi standard, etc. They can combine the band into a single SSID (Smart Connect) or use them separately.

QoS-based gaming features

MSI’s gaming features are pre-programmed Quality of Service settings, called AI QoS, similar though not as in-depth as the case of Asus’s Adaptive QoS.

Within the web interface, the Game Center section duplicates a portion of the router’s AI QoS section.

MSI, for now, doesn’t offer true gaming features available in Asus gaming routers or those powered by DumaOS, such as ping management or private gaming network.

MSI RadiX AX6600 Game Turbo BoosterMSI RadiX AX6600 QoS Features
MSI’s “gaming” features are part of its firmware’s QoS.

In short, it’s a bit of a stretch to call MSI hardware “gaming routers”. But you can play games with them, just like the case of most Wi-Fi routers.

Simple Parental Control

An MSI router has a simplistic Parental Control feature that limits Internet access or blocks connected clients using six pre-determined categories: Adult, Illegal (drugs, firearms), Gamble, Malicious (phishing, attack, virus), Violence, and Game.

It’s unclear what each category entails, and no way to define it further. Consequently, it’s hard to know its effectiveness.

Moreover, you have to block/limit access to one client at a time instead of creating a group to manage multiple users in one place.

MSI RadiX AX6600 Parental ControlMSI RadiX AX6600 Time Schedualing
The Parental Control feature is quite simple.

It’s important to note that the Parental Control features and the web filtering of MSI’s firewall are based on clients’ MAC addresses. As a result, they can be easily circumvented via MAC spoofing.

MSI and your privacy

While you can use an MSI router without surrendering personal information by default, activating some of its features, including AI QoS and Parental Control, means you’ll have to share your Internet traffic with GT Booster, which powers the router’s said features.

That’s the case with all routers with these features. Similar to real life, we can’t have our business or security taken care of without involving a third party.

Here’s GT Booster’s privacy policy.

Single VPN option

For now, MSI routers’ support for VPN limits to the OpenVPN protocol. This is not bad since this is the most advanced VPN option.

The drawback is that you’re out of luck if you want a more popular VPN server, such as PPTP or L2TP/IPsec, with client support readily available on devices.

Extra: Popular VPN server options

Below is the list of VPN protocols collectively available in-home Wi-Fi routers. Most routers support just one of them, while others might support all.

PPTP

Short for point-to-point tunneling protocol, PPTP is the oldest among the three.

First implemented in Windows 95 and has been part of the Windows operating systems and many other platforms since PPTP is well-supported and the easiest to use.

However, it’s also the least secure. It’s better than no VPN at all, and it does its purpose of making a remote device part of a local network.

That said, if you take security seriously, or have other options, skip it. On the other than, it sure is better than nothing and good enough for most home users.

L2TP/IPsec

Short for Layer 2 Tunnel Protocol is the second most popular VPN protocol — it’s also a built-in application in most modern operating systems — and an interesting one.

It has no encryption by default, so it’s not secure where the IPsec — or IP security — portion comes into play to provide encryption. Therefore, this protocol is rigid in port use and can be blocked by a third party.

The point is L2PT/IPsec is great when it works. And it does in most cases, which ultimately depends on whether the local network of the remote device allows it to pass through.

OpenVPN

As the name suggests, OpenVPN is a flexible VPN protocol that uses open-source technologies, including OpenSSL and SSL.

As a result, it has a high level of customizability and is the most secure. It also can’t be blocked.

In return, OpenVPN requires extra client software, making it less practical. But this protocol is the best if you want to be serious about VPN.

No Dual-WAN or Link Aggregation

MSI’s new routers come with a 2.5Gbps Multi-Gig WAN/LAN port. You can use it as a WAN (default) or turn the router’s first LAN port into that role, making the Multi-Gig port function as a LAN.

And the port flexibility ends there. For now, MSI doesn’t support Dual-WAN or Link Aggregation. And you can’t turn the USB port into a WAN source, either.

MSI RadiX AX6600 LAND WAN port
Depending on your Internet speed, you can use the MSI RadiX AX6600’s default Mulit-Gig WAN port or its first LAN port as the WAN port.

No mesh support

MSI routers, for now, are meant to be standalone Wi-Fi machines. They don’t support add-on mesh features like AiMesh of Asus or OneMesh of TP-Link.

Consequently, they will work great for homes that need just one broadcaster or those intending to extend their Wi-Fi network via standard access points or extenders.

If you want to scale up your network in a seamless way, there’s no option for that from MSI. At least, not yet.

Standard network settings

Like most routers with a Linux-based local web user interface, an MSI router comes with a standard set of network settings, including a DHCP server, port-forwarding, MAC filtering, IP reservation, IPv6, a simple Firewall, and so on.

Notably, most of these settings are less refined than other routers. Take IP reservation, for example; you’ll have to manually enter each entry’s MAC address, which can be a pain. There’s no option to reserve the IP of a connected client by interacting with it on the network map or selecting it from the connected client list.

No built-in Dynamic DNS support

The most surprising and disappointing of MSI’s router firmware is that it doesn’t have built-in Dynamic DNS client support. Specifically, the router won’t work as the device that binds the WAN IP and a DDNS domain.

This is likely the biggest shortcoming of MSI when compared to other networking vendors. Asus, for example, even provide a free DDNS domain for each router.

An MSI router will still work for those needing DDNS, but a separate DDNS updater, such as a NAS server or an always-on local computer, is required within the network.

SMBv1 is still required for network storage

MSI routers with a USB port can work as a mini NAS server. In this case, you can plug an external hard drive into this port, and the router will work as a DNLA media server or a file server. It even also works as a BitTorrent PC-less downloader.

MSI RadiX AX6600 SMB1 Message
MSI’s USB-based network storage requires SMBv1 to work.

And all that works. However, the network client, such as a computer, must support the dated and vulnerable SMBv1 protocol if you want to access the shared folders hosted on the router’s connected USB drive.

Due to security reasons, most devices don’t use this protocol anymore — it’s disabled by default. So taking advantage of an MSI router’s USB port might mean you need to downgrade your network’s security. At least, that’s the case until SMBv2 or later is supported.


In short, MSI has a promising approach to home networking, and its router firmware has a lot of potentials.

While for now, the firmware is still thin on features and lacks depth in configurations. Hopefully, it’ll get better as time passes. And the simplicity has its upside, too. There will be fewer bugs, like in the case of Asus routers.

With that, let’s look at the RadiX AX6600 as a Wi-Fi 6 router.

Hardware specifications: MSI Radix AX6600 vs Synology RT6600ax

While on the firmware front, the new router reminds me of Asus; spec-wise, it’s identical to the Synology RT6600ax. Specifically, it’s a lopsided Tri-band router with two 5GHz bands of different specs.

MSI Radix AX6600 vs Synology RT6600ax: Hardware specifications

MSI Radix AX6600: Excellent and reliable performance

I tested the MSI GRAX66 for over a week and was happy. The router worked as intended and didn’t have any disconnection during my multiple-day stress test.

Since this is the first Wi-Fi 6 router from MSI, I’ll keep using it for a while and will update if I run into any issues during long-term usage.

OK network storage performance (when hosting a portable SSD)

Like the case of the Synology RT6600ax counterpart, the MSI Radix6600 didn’t have much to call mom about its storage performance.

Hosting super-fast portable SSDs, the router’s performance was much lower than the 2.5Gbps wired connection I used for the testing, especially in writing. But it’s read fast enough for light network attached storage needs.

Considering the SMB1 requirement mentioned above, if you’re serious about NAS, my advice is always to get a real server.

Network storage requires SMB1 with mediocre write speed

Conclusion

The MSI GRAX66 RadiX AX6600 is an excellent standalone Trib-and Wi-Fi 6 router considering its friendly $249.99 price tag.

Still, in many ways, it’s merely another Wi-Fi 6 broadcaster among many excellent options. After all, Wi-Fi 6 has been the mainstay for a long time, and it’s even on the way out, considering Wi-Fi 6E and the upcoming Wi-Fi 7.

You can easily upgrade this router, or any Wi-Fi 6 network, to Wi-Fi 6E via a switch.

However, as a home networking device representing MSI, it’s an exciting product that gives consumers more choices in the future. And competitions are always great. You can get the RadiX AX6600 to check out a new MSI router today or keep the brand in mind for future consideration.
