Some had that problem before, make sure to select a channel on the Radio1, auto does not work and it will set it to client, as it goes into client mode first to look for free channels, but never comes back apparently.

Any updates on WCS not working? i only get minimum bitrate even with max signal and i cant transfer faster than 20MB/s over Wireless 5ghz N or AC.

1) latest from trunk, so the vlan stuff should work if you install the packages through opkg. minimal build so I have not expanded the packages more than the "bare" minimum. However for a "known-good" I will try to incorporate openvpn, security, and vlan

2) no extra security except for https and ECC for dropbear (ssh) i believe. Still trying to figure out how to use ecc any help? @mmilburn

I really want the next "Known-good" to be as close to production ready release, however i know the limitation will always be CC not being finalized as well as the wireless driver still being in it's infancy

Ok managed to change the wifi password by editing the etc/config/wireless file with vi.
Using uci didn't do it for me...
Even with the right password in the file, LuCI still shows me the wrong password (seems to be the root password). I don't know if it's a bug...

It's your web browser password manager. Mine does it too, I just retype the password i want, then click save and apply. Then it all worked fine

@brandthought

Your last resort is the USB TTL cable. Use the wiki here: http://wiki.openwrt.org/toh/linksys/wrt1900ac

Sounds like you ran into the issue I had. If you saved the root password on the login screen and its showing up in the Wifi auth key area then you'll have to remove the saved password from your browser and this will clear up the issue. You can't save the root password for login or it screws with the wifi auth key.

Or, depending on your password managers capabilities, set it to not auto-fill on your router web address.

I tried to find workarounds for the bad autofill but didn't succeed yet. The problem is the browser heuristic, so it does not help to rename the field as it already differs from the login field name. If someone knows a workaround for that I'd appreciate any suggestion...

I'm following this thread for some time now. As the wifi drivers are now available, i tried to compile my own image. But i can't seem to get it to compile.

Hi...

Just want to share that I've tried to download from lifehacksback's testing link, but can't get the radio0 working on 2.4 Ghz. and the kernel seems to be still 3.18.1 not 3.18.2. an the img file name is openwrt-mvebu-armada-xp-mamba-squashfs-factory.img.

It seems like a wrong file.

Anyway, I've just flashed it again with the known-good version and it works!
Currently running on both 2.4GHz (radio0) and 5GHz (radio1).

Thanks lifehacksback for the image.

Happy...

Can someone please test wifi AC 5GZ speed. It seems to link at 433Mbps (megabits) for me but actual file transfer speeds are around 100Mbps ( about 10MB/sec). Whereas with stock linksys FW i get over 230Mbps file transfer speed from my NAS over wifi. Everything is also on wired gigabit Lan.

I have another AC router (Tp-Link Archer C7) acting as a wireless bridge to my downstairs media center.  Its associating at around 400Mbps (should be 800Mbps, but thats another issue I'm trying to sort out) and I'm seeing good speeds.   Doing a file transfer over the bridge i'm seeing anywhere between 30MB/sec to 20MB/sec

@camrxr  hmmm thanks. I'll do some more tests.

so your media center is hard wired into the TP link which acts as a wireless client of the linksys wrt?

In essence, yes.

I'm very new to open wrt. Long time DD-wrt user. Trying to setup adblock. It requires package " iptables-mod-nat-extra". When i try to install it, im getting the following.

im running: OpenWrt Chaos Calmer r43853, which includes kernel " 3.18.1-1"

Thanks for the video lifehacksback, I wish I had this 2-months ago when I bricked the router ;-) I've been following this forum since July and I wanted to say thanks to you Chadster, nitroshift, Kaloz, and everyone else who's been involved with bailing out Linksys by bringing open source support to the 1900.

I've been running the latest version of McWrt AA and decided to try the OpenWrt Chaos Calmer, both your version and the Kaloz's version, and have run into the same issue with both: the WAN interface never gets its DHCP config info from my ISP (Time Warner Cable). The WAN interface is setup to use DHCP, and it works fine with the latest version of McWrt AA (12.09.1 | Load: 1.17 1.19 1.11 ). I tried to compare all of the network and interface settings, but I must be missing something. As a result, I've had to revert back to McWrt AA, but I'd really like to be using CC as that seems to be the way ahead. Any help would be greatly appreciated - thanks!

I don't think so, looks like it's.

Why would you need it? We do have an ntp client and server in there

It's packaged, but we don't officially support it yet.

Trunk uses 3.18.2 by default now.

Excellent!

Cheers from Calgary CA

How did you upgrade? Did you McWRT --> linksys --> CC? If you dont have a usb-to-tty follow that upgrade route Also yes the name of the package *is* openwrt-mvebu-armada-xp-mamba-squashfs-factory.img That's the name after compile

Update:
I'm sorry you were right I guess the link to a specific file will do just that I updated the wiki to link to a specific folder where i will be uploading the *correct* updated img Sorry about that

In neither McWRT AA or OpenWRT CC have I been able to get the built-in server to work - the (LAN) clients just don't want to connect.  Stopping the built in one, installing the ntpd package, and starting that, all clients connect successfully to the router.

I can see what reference server is currently selected by running ntpq -p on the clients, but this won't tell me the other servers the router is or isn't also taking into account, nor what the router's stats (offset, etc.) are.

As mentioned ntp-utils (and thus ntpq) was available in McWRT, but not for OpenWRT CC/Trunk.

I had started a new thread for another of my issues but thought i would put it here too as this thread is wrt1900ac specific.

To keep it short and simple. I have all wired gigabit network. All pc's, NAS are hard wired.
Router: wrt1900ac, running "OpenWrt Chaos Calmer r43853 "

radio0:Wifi N only, 40MHZ,
radio1: Wifi AC only, 80MHZ, channel 48 (complete free, no other routers around)

With stock linksys FW my wifi AC speeds are pretty good . I'm testing with my phone. I can hit 22 MB/sec for file transfer from my NAS

With openwrt my wifi AC speeds are less than quarter of the oem. I get about 4.8MB/sec.

Am i doing something wrong? Could somone please help me with some suggestion or some key config i might have forgotten.

Even though the wifi client is connected at over 400Mbps, this is what i see under the wifi radio on the router, it shows bitrate to be 6Mbit for some reason, even though my file transfers seem to be happening at 55mbits:

I also note that while it is admittedly quite out of date in content, the openwrt wiki does state "If the default ... isn't sufficient, one of the following alternate ntpd packages can be installed" - and lists ntp-utils as one of them.
