4.0 out of 5 stars RT-AC57U v1 first glance and VPN
Reviewed in the United Kingdom on 27 January 2020
I bought a 'Warehouse' edition of this router with the intention of using it as a wireless access point, connected by long ethernet cable back to main router. The RT-AC57U v1 has been on special offer a couple of times at 33 squid. At its normal selling price hovering under 50 squid, it is less of a bargain imho.

As mentioned by others, the Quick User Guide is all but useless. There is no online Full Instruction manual I could find for the v1 model, but there is an online user manual for the v2 model.

v1 vs v2 vs v3:

There is the original RT-AC57U and a newer RT-AC57U v2 announced in Aug 2019. The 'Warehouse' model I received was a v1.

The original v1 is a rebadged RT-AC1200GU which has been around for a few years. It is powered by dual core 880MHz MT7621AT MIPS processor. 128MB RAM and 16MB flash with gigabit ports and one USB2 port.

The v2 is powered by new 775 MHz Qualcomm QCA5502 MIPS processor. The QCA5502 MIPS processor is only single core like other similar QCA processors found in many low budget routers.

Asus announced the new v3 in March 2020. Specs have been published on Asus USA website and look the same as the v2, but with greater 32MB flash and support for AI-Mesh.

Amazon DE and ES both the original RT-AC57U and new RT-AC57U v3 as separate products for sale. Amazon FR still offering RT-AC57U v2. Overclockers in UK did briefly offer the v2 as of Sept 2020. No sign of v3 coming to UK.

Key firmware differences is the v1 supports 3G/4G usb dongle sharing and offers Router, Bridge (Access Point), and Repeater mode. No VPN options 'out of the box'.

The new v2 and v3 offers Router, Bridge (Access Point), Media Bridge (aka Wireless Bridge) modes. VPN support is also included unlike v1.

Adding VPN:

However, OpenWrt is available for the v1. OpenVPN VPN client on OpenWrt is capable of up to 19 Mbps in testing. A Padavan fork, and AsusSrcMod firmwares hosted on ixbt forum, are also available and offer OpenVPN VPN client & server. - do a web search for 'RT-AC57U ixbt'. I can confirm AsusSrcMod firmware works with my VPN provider using openvpn VPN protocol - the AsusSrcMod firmware looks exactly identical to original Asus firmware but with inclusion of VPN menus.

USB2 port:

I briefly tested the USB port. Copying a large file from USB2 via 5 GHz 802.11ac wifi to a laptop achieved steady 18 MBytes/sec using samba file sharing according to Windows 10 file explorer. Writing same file from laptop to USB flash drive via wifi was a different story. The 1GB copy test failed half way. I will investigate it later. It could be the flash drive, USB/wifi interference, or some other issue. Update: I tested a USB3 Kingston DataTraveller Ultimate flash drive which is normally capable of 60MB/sec Write speeds. When copying same file, it managed 18MB/sec read and about 7-9MB/sec write speeds over 5 GHz wifi. My flash drives were formatted FAT32. Asus wouldn't work with exFAT.

The Media server also works with our smart TV which uses DLNA. Both samba and DLNA functions worked when the v1 was configured in Bridge mode (Access Point) too. I didn't test the FTP server function.

Wireless Access Point:

In Bridge (Access Point) mode, you are offered the option to let the Asus use DHCP to automatically obtain a valid IP address, gateway and DNS settings from your main router. There is also the manual option to use static IP settings. I have observed this bizarre behaviour whereby if you configure invalid IP addresses on the Asus whereby the Asus is unable to reach the internet (eg. for system time), then wireless devices can connect to the Access Point but will not be able to access the internet because it appears DNS is not working! Websites can be pinged by their IP address (eg., but not by their DNS name. It's as if the Asus in blocking DNS requests packets.

The RT-AC57u was installed at a remote small business site, to see if it would resolve an issue where a Brother MFC-L2710DW MFC laser printer could not connect to an existing old 2.4 GHz 802.11g Access Point separated by 2 stud walls. A new iphone (11?) used in same room also suffered from severe buffering.

Unfortunately, the Asus made no significant difference. The printer could see the SSID but just would not connect. It wasn't any better for the iphone. The Asus was subsequently removed after a few weeks and redeployed at home as a router wired to Virgin Cable.

Several months later, a Linksys EA6350 v3 replaced the antique 802.11g Access Point. To our surprise, the Brother printer could successfully connect to the Linksys WAP. The iphone also had no issues connecting to wifi, but it was observed the iphone couldn't consistently discover the Airprint capable Brother printer. Laptops had no trouble printing. Pinging the printer's IP from the main network revealed the ping times were all over the place, up to 250ms, unlike the ping times between iphone and network of 1-2ms. The Airprint issue was resolved by ethernet wiring the Brother MFC printer to the main network.

Update 1: OpenVPN client router

I flashed 'AsusSrcMod' using Asus web UI to my RT-AC57u v1. I simply added a new profile anduploaded the .OVPN file supplied by my VPN provider to connect to nearest VPN node. See attached image of VPN menu.

Speedtest.net returned 18.6 Mbps download to ethernet wired PC which is what I'd expect from MT7621A powered router. (If you want faster speeds over ethernet, consider RT-AC86u which can do 75 Mbps openvpn speed out of the box, ,or up to 170 Mbps with RMerlin firmware according to PIA blog) Only downside with Asus openvpn client is I can't see a 'kill switch', so if the VPN connection fails, I guess the router will probably just switch all traffic originally intended for the VPN tunnel, to go via the regular internet connection. A kill switch can be implemented with OpenWrt btw.

Update 2: Wifi Router for Virgin Cable

Installed another RT-AC57u as a wireless router wired to Virgin Hub 3 (modem mode), to see if it would resolve recurring intermittent 5 GHz wifi stability issues with the Hub 3, whereby a random device would be connected to 5 GHz wifi and using internet, and then suddenly there would be no internet connection even though there is good signal (eg. 3 bars) while streaming for example - disconnecting then reconnecting device to 5 GHz SSID would resolve the problem. No other wifi devices lose internet when above happens.

The AsusWrt interface is generally good and provides all the usual router functions. The interface is a bit 'clunky' in a couple of places. eg. you cannot enable/disable port forwarding rules. To disable a rule, it has to be deleted. A few settings force a shut down and restart but there is no warning in case you don't wish to proceed.

As of end of September 2020, the Asus was up continuously for 170+ days elapsed since it was last rebooted, before it was taken down for 5 minutes by a street wide power cut! Up to a dozen phones, tablets or laptops are frequently connected to 5 GHz SSID, and half a dozen devices (cctv) are 'constantly' connected to 2.4 GHz SSID. The problem where random wifi devices lose internet access on 5 GHz band but still seeing strong wifi signal is has been resolved - confirming it was an issue when Hub 3 was used as a 'router' . 5 GHz Wifi apparently seems to be more reliable/better speeds to the kitchen separated by a hall way and breeze block internal walls - up to 50 mbps reported by iphone from M100 broadband service.

The 2.4 GHz band isn't used by smartphones/laptops because of existing wifi interference from neighbours but existing Yi home cameras seem to function ok. Where an iphone has accidentally connected to the 2.4 GHz SSID, it seems to work ok. Preference is to use 5 GHz SSID in the household even though its range/coverage is shorter.

I should add when the Asus was first set up, its SSIDs were configured to match those of the Hub 3, so that existing wifi devices could easily connect to the new Asus without having to type in the wifi passwords. One particular iphone refused to connect to the 2.4 GHz SSID - it kept prompting for the password when iphone was only a few feet from the Asus. Another iphone didn't have this issue. We knew the stored password was correct so did not retype it. We solved the problem by manually changing the wifi channel number on the Asus. As mentioned earlier, 2.4 GHz wifi interference from neighbour(s) has caused problems in the past.

Update 3: Wireless Bridge using Padavan firmware

Essentially, a wireless bridge is a glorified ethernet-to-wifi adapter (Asus call it a 'Media Bridge'). It permits up to 4 ethernet wired devices to be able to connect wirelessly to main wifi router. The RT-AC57U v1 does not offer Wireless bridge (Media Bridge) mode with original AsusWrt firmware. However, 3rd party firmware from Padavan hosted on ixbt forum does offer wireless bridge functionality (Padavan call it 'AP client') and it works very well. Assign a new static IP address to the Asus and don't forget to disable its DHCP server - see Image of Padavan firmware 'AP client' wireless bridge setup page.

The 'Repeater' function in the Asus firmware can be used as a ethernet to wifi adapter too, except for one key difference. A repeater also serves a wifi signal to any wireless devices within range - this may not be desirable in some circumstances.

Wireless range:

If you are looking for a new router with super long range/wider coverage on both 2.4 and 5 GHz bands and/or able to penetrate thick internal solid walls, then this Asus is NOT for you. You should consider mesh wifi solutions where greater 'coverage' is required at the expense of speed, perhaps with hard wired backhaul ethernet connections if there are thick internal walls.

Installing a single wall mounted wireless access point/router in dead centre of property may be another option to improve coverage. The wifi signal has less distance to travel in all directions to reach all four corners of the property.

Compared to Virgin Hub 3, we haven't found the Asus to be better than Hub 3 for coverage when using 5 GHz wifi. ie. if you have poor coverage from Virgin Hub 3, don't expect the Asus to offer a massive improvement - you will be disappointed.

AsusWrt firmware versions

The Wireless Access Point, and Router connected to Virgin Cable, are both using Version (Dec 2018). There is an all new Version (May 2020) - not installed yet as of July 2020 - if it ain't broke, why change it?

When does v2 or v3 go on sale?

If you bought a new RT-AC57u recently, please let us know if it is a newer model (Label on bottom of router should say RT-AC57U v3 I guess) in the comments.

What are alternatives to RT-AC57u for use as a router or wireless access point (no VPN)?

Linksys EA6350 v3, is Qualcomm quad core ARM powered AC1200 gigabit router with USB3 socket. v3 is almost discontinued because new inferior v4 Mediatek MIPS powered model was recently launched in USA.

TPlink Archer C6, is Qualcomm single core MIPS powered AC1200 gigabit router (similar to RT-AC57u v2). Essentially same as an Archer C7 but missing USB2 sockets and one less aerial.
