downlink is gigabit good.
2022-07-02: uptime (via web gui) is 260 days, I can't ssh into the box (tried 3 times), so I reboot it from web gui. Afterwards ssh works

2021-07-07: I re-created this page on my self-hosted web server.
2020-12-08: reboot - I rebooted the AP again.
2020-05-10: reboot - a few of the mobile devices acted up (as if there was no connection / no dns) so I rebooted the AP again.
2020-04-01: reboot - I rebooted the AP. Yes - now I have much better throughput on my WLAN again.
2020-03-27: moved to channel 7

hmm, looks "normal".
2019-09-20: rebooted the AP, to see if performance will improve (my cell phone complained about "no internet" in some apps). Yes - rebooting helped, my cellphone stopped complaining.

ok
2018-09-17: the access point have been getting worse and worse the last few weeks; lots of dropouts, connections that don't work and so on. Today I first tried rebooting, but then no devices could get on the net afterwards. Checked the switch that the AP is connected to - no connectivity light on that port. Bad cable? I changed the cable - yes, that was the problem.
2018-08-08: OpenWRT claims that the Asus RT-N16 is supported in 18.06.0, but it seems you need kmod-brcm-wl, wlc and wl packages for full Wi-Fi functionality. alternate: kmod-brcmsmac or kmod-brcmfmac for an open source driver with better functionality than the standard driver (still not as good as the proprietary driver though).
2018-08-08: reboot - the music players (Squeezeboxes) lost connection all the time, so I rebooted this AP.
2018-01-24: no extra lines in my firewall log today. So yes - rebooting the AP helped.
2018-01-23: reboot - some of my machines (including my Fedora laptop just upgraded to F27) is showing lots of disconnects in the firewall log. In a fault finding effort, I'm restarting my AP to see if that affects anything. Before restart:
tingo@kg-core1$ ssh root@rt-n16 root@kg-rtn16.kg4.no's password: Tomato v1.28.0000 MIPSR2-140 K26 USB AIO ======================================================== Welcome to the Asus RT-N16 [TomatoUSB] Uptime: 09:47:31 up 98 days, 18:34 Load average: 0.08, 0.03, 0.00 Mem usage: 16.4% (used 20.31 of 123.87 MB) LAN1 : 10.1.10.11/16 @ DHCP: - WL0 : 2,4GHz @ kg5 @ channel: NO13 @ E0:CB:4E:86:81:0B ========================================================
it doesn't look overloaded.
2018-01-15: This afternoon I switched to channel 13 (better signal):

check TID
root@kg-rtn16:/tmp/home/root# nvram show | grep http_id http_id=TID7c1dcbedd6ca3a4e
it is unchanged.
2017-09-17: upgrade - Tomato by Shibby 1.40 has been available a while now. Let me upgrade. First I switched to a different wireless AP for my laptop, then I selected Administration, Upgrade in web gui, and since I want ot keep my settings, I didn't check the "After flashing, erase all data in NVRAM memory" checkbox. Then I pressed "Upgrade". After a while (about 3 minutes plus) the browser said "Image successfully flashed", "Please wait while the router reboots...".
2017-09-17: the AP (access point) has been up 314 days now:

2017-08-05: LEDE claims support for this router. Not sure if it works - haven't tested it.
2016-11-06: check TID

it has changed.
2016-11-06: connecting via ssh:

it works now.
2016-11-06: upgrade - I decided to upgrade to latest Shibby (138), the file is tomato-K26USB-1.28.RT-MIPSR2-138-AIO.trx. I connected my Fedora laptop to my other wireless network (useful), and selected Administration, Upgrade in web gui. I selected "After flashing, erase all data in NVRAM memory" to have NVRAM cleared, then pressed "Upgrade". after a while, the browser said "Image successfully flashed", "Please wait while the router reboots...". I connected another laptop via ethernet cable to the router, started a browser and pointed it at 192.168.1.1, logged in with default username and password (admin). configured the router, leaving the local network settings (IP address, gateway, DNS server, disable DHCP server) for last). Then I connected the router (ok, access point) back to my network. It works.
2016-11-06: new software: EasyTomato, newest release is from 2013, Toastman - hard to figure out which version you need, Victek - newest release is from 2014, AdvancedTomato - new release for the RT-N16 from 16.8.2016 is 3.3-138, but the only change from Shibby is the gui part. Shibby release 138 is from August 2nd, 2016.

useful.
2016-11-06: trying to connect from my Fedora laptop:
[tingo@localhost ~]$ ssh root@kg-rtn16 Unable to negotiate with 10.1.10.11 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1
ok, try from my FreeBSD workstation instead:
tingo@kg-core1$ ssh root@kg-rtn16 root@kg-rtn16.kg4.no's password: Tomato v1.28.9054 MIPSR2-beta K26 USB Ext
I should probably upgrade the router.
2012-04-03: TomatoUSB setup: WAN disabled (use WAN port for LAN), I setup the LAN IP address, gateway and DNS static, turned off the DHCP server, set the WLAN as access point. with WPA2 Personal. I started the ssh daemn, and stopped the telnet daemon.
2012-04-03: I flashed TomatoUSB on the router by following this guide, the RT-N16 has a MIPS R2 cpu, and I used Build 54, Kernel 2.6, Ext. I tried build 54 twice; it didn't work, I always ended up in recovery mode (slow flashing power LED). Next up is build 52. No, that didn't work either. So I'll just flash DD-WRT onto the router as an intermediary step. Using tftp again. Hmm, I figured out why it didn't work - user error; I must put tftp into binary first. Like this:
$ ls *trx $ tftp 192.168.1.1 tftp> bin tftp> put dd-wrt.v24-13309_NEWD-2_K2.6_mini_RT-N16.trx tftp> quit
Will it work now? Yes, it did. So, let's re-try with the wanted firmware:
$ tftp 192.168.1.1 tftp> bin tftp> put tomato-K26USB-1.28.9054MIPSR2-beta-Ext.trx tftp> quit
wait five minutes, then power-cycle the router.
