ASUS RT-AC88U Router Review
The ASUS RT-AC88U was launched in Singapore at SITEX 2015. SITEX is a consumer lifestyle IT event in Singapore and is usually the last major IT event for the year. It is always held at Singapore Expo and this year, the event took place from Thursday, 26th November 2015 till Sunday, 29th November 2015.
The retail price of the ASUS RT-AC88U Router is S$429.
The much awaited Asus RT-AC5300 (the eight antenna router that looks like a spider) was launched at SITEX 2015 as well and that is retailing for S$469.

The RT-AC88U comes with a 4×4 antenna design and it is MU-MIMO enabled. If you are interested in knowing what MU-MIMO is all about, check out my review on Linksys EA8500 AC2600 MU-MIMO Router.
The design looks almost the same as every other Asus routers out there.
Having said that, the design of the router is nothing much to rave about. Asus routers are not really well known for it’s design but rather it’s performance.
The first thing that caught my eye about this router is that it has eight LAN ports whereas most routers in the market have only four. The last time I used a router that has more than four LAN ports was the Western Digital My Net N900 Router three years ago.

There are two USB ports on this router, one is at the back which is a USB 2.0 port and one hidden in front on the left of the router which is a USB 3.0 port. Personally, I never used the USB port feature of my routers.
The router also supports WTFast.
WTFast is the Gamers Private Network (GPN); like a global automated army of IT specialists all working together to optimize your game connection from end to end. WTFast reports rich connection stats for your online game, so you can see exactly what is happening with your game connection.
WTFast is not a free service, it costs US$59.90/year (S$85/year) for the basic plan and US$99.90/year (S$140/year) for the advanced plan.
However, the Asus RT-AC88U is the first router with this featured built-in and is bundled free for life.
I have used Linksys and D-Link routers before and I find that overall Asus Admin UI is the best. It might not be the best looking, but it is functional and fast.
Linksys Admin UI is nice but slow, D-Link Admin UI is fast but menu items are hard to find.
Asus on the other hand is slightly ugly but I like the menu items on the sidebar followed by the tab pages on the main content is simple and straightforward to find.
The RT-AC88U supports dual-WAN. This means that if you have two separate Internet connections at home, this router can support both. There are two modes to dual-WAN, Fail Over or Load Balance.
Fail Over means if one of your Internet connection is down, it will switch to the other one.
Load Balance means it will use both Internet connection at the same time and gives you the fastest possible speed from either of your Internet connection.
The secondary Internet connection can be either from a 3G/4G USB dongle or from any of the first four LAN ports.
You probably need VLAN tagging if you are not on Singtel’s unlimited fiber plan or are using StarHub. I have problem finding where the VLAN tagging menu item is and I have to Google to find out.
It is under LAN -> IPTV tab.
I have no idea why Asus would classify that under IPTV because you will still need VLAN tagging regardless whether you are using IPTV or not.
Calling it VLAN Tagging instead of IPTV will make it more generic and obvious to people.
Most routers I reviewed so far supports the router being a VPN server but doesn’t support the router being a VPN Client itself.
This is where Asus routers differentiate themselves. Having the router act like a VPN client is good because it allows everyone that is connected to the router to proxy through the VPN so that you can watch/purchase content that is available in the US only.
For routers that doesn’t have the VPN Client support, you have to use SmartDNS which doesn’t work for me these days on Singtel.
Personally, I find it better to use a VPN because it works 100% of the time rather than SmartDNS where sometime it works, sometime it doesn’t, depending on the traffic and your ISP.
This is a common issue in countries where the Internet is censored at the ISP level, or if the ISP is using special routing methods such as pools of IP addresses or different IP for each HTTP request. Most Singapore ISP’s such as Singtel and Starhub are known to employ such features that break full third-party SmartDNS support.
I am using the WiFi Explorer app on my MacBook Pro to test the wireless strength of two extreme corners of my house, my room and the common toilet.
As you can see from the table below, the wireless signal strength of the RT-AC88U is fantastic. Overall, it is probably the best router that I have reviewed in terms of wireless coverage.
|My Room (2.4GHz)||88%||85%||85%||55%||76%||79%|
|My Room (5GHz)||82%||82%||76%||27%||78%||91%|
I started using iPerf to test the speed of the router rather than my usual Speedy Net app on Mac because it is more accurate and gives a more detailed breakdown.
Maybe because it is more accurate, in all the three tests I ran, LAN to LAN, LAN to wireless and wireless to wireless, the RT-AC88U beats all the previous three routers that I reviewed.
|LAN to LAN||940Mbps||932.71Mbps||886.36Mbps||876.2Mbps||780.27Mbps||500.19Mbps|
|LAN to Wireless||213Mbps||175.87Mbps||173.49Mbps||97.64Mbps||146.14Mbps||217.61Mbps|
|Wireless to Wireless||145Mbps||119.70Mbps||98.79Mbps||50.53Mbps||146.91Mbps||75.71Mbps|
The ASUS RT-AC88U is probably the most expensive router that I came across and it is not even the highest end Asus router. The RT-AC88U retails for S$429 which is S$30 more than the highest end routers from Linksys and D-Link at S$399.
Given that the RT-AC88U has much more features than the highest end routers from Linksys and D-Link, I find that the S$30 more is justifiable.
I do stream Netflix to my Chromecast regularly. Having a VPN client support is important to me because my SmartDNS is not working ever since I switched to Singtel.
Dual WAN is a good option to have for businesses that have dual Internet connections for contingency purposes.
You will probably not go wrong with the RT-AC88U because of the huge amount of features that they have and I am sure your use cases will be covered in those features.
As a reminder, the RT-AC88U supports MU-MIMO which I am guessing will be the next in-thing for wireless technology next year! So this makes the RT-AC88U future proof as well.
- Good wireless coverage
- Good wireless and wired speed
- VPN server & VPN client support
- Dual WAN support
- Slightly pricey
- USB 3.0 Port located in front
- IPTV should be renamed to VLAN Tagging
