Likely because the u-boot variable name isn't "firmware_name.img" but "firmware_name"

You mean no extension needs to be specified?

ok another weird thing..I've always used dns based ad block for which dnsmasq read a hosts file from the mounted usb drive.

Today, i dont know if it has something to do with new build (r45250) or what, but dnsmasq is unable to read the file.
The file permissions are ok. Owner is root. i've even given it 777 permission. Still doesnt work. However if i put the file on e.g /etc. Then it is read fine

Fri Apr 3 23:15:53 2015 daemon.err dnsmasq[6943]: failed to load names from /mnt/sda1/scripts/hosts.block: Permission denied

USB is ext4, mounted as RW. i can read the host file fine via ssh. I deleted and recreated the hosts file but no luck.

Any clues?

EDIT: I think i found perhaps why. Looks like the dnsmasq process is not running as root for some reason. This is what i see in "ps"

6994 nobody 1852 S /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf -k -x /var/run/dnsmasq/dnsmasq.pid

EDIT 2: Apparently DNSMASQ in general downgrades itself to nobody from root after starting up as root. So the question is if that behavor is normal then why the permission error? a few builds back this was working fine and i never had any problem.

No, he means you need to set the environment variable firmware_name to the name of the image.
How do you think uboot will locate the value set if it isn't assigned to a specific name.

Just to clarify I was using this command: setenv FW_WRT1900AC_1.1.8.164461_prod.img

Anyways obviously something was not working as it should have as boot kept expecting a name like blkmamba.....

For me, renaming the firmware image to something easier to type helps...

After I download the firmware, I rename it to "1", or something easy to type.

setenv firmware_name 1.img

Hope that helps.

the wiki really needs updating!
If someone has time, we need to:
1) change the McWRT entry to say it is out of date, no longer supported and has likely now been surpassed by Trunk. Remove the .img link.
2) make the CC snapshot the current recommendation
3) remove lifehacksback builds
4) keep Kaloz's link
The "How to flash the firmware to device?" bit needs references to mcwrt (build 1 / 192.168.200.1) removed.
Need to add the luci/httpd instructions to trunk section.
The "disassoc_low_ack=0" fix section it now appears can also be removed.
Done.

I reorganized some of the info on the wiki page, de-emphasizing old/obsolete historical info, and making it easier for new people to get to the current info & builds. Please check that I've maintained the truth invariant...

Ah OK..got it..I misread the part " firmware_name"
So its a parameter for the setenv command followed by the .IMG file name itself

Correct.

@grimley & others

Firmware images built with latest iteration of kernel 4.0 are primarily for testing purposes such as bacporting fixes to current trunk kernel. For example, the cpuidle patch was backported from such a test build.

Anyone tried playing with VLANs?
I would like to add tagged VLAN2 to port 1.
According to https://s3.amazonaws.com/Justin.Schuhma … layout.png its no. 3.

config switch
        option enable_vlan              '1'
        option name                     'switch0'
        option reset                    '1'

config switch_vlan
        option device                   'switch0'
        option ports                    '0 1 2 3 5'
        option vlan                     '1'

config switch_vlan
        option device                   'switch0'
        option ports                    '3t 5'
        option vlan                     '2'

config switch_vlan
        option device                   'switch0'
        option ports                    '4 6'
        option vlan                     '3'

So I have changed /etc/config/network as in above but not I cannot connect to any LAN port... ideas?

Could you also paste the rest of /etc/config/network?

In the VLAN 2 switch_vlan entry, you need to add tagging to the CPU port (5). Then, create a network entry for eth0.2 with the desired config for that VLAN.

I believe there was new wireless driver that was commited on APR 2nd. Did that make its way in yet?
secondly has anyone done a real world test of AC wifi speed e.g file transfer and not with iperf?

Looks like its working now. Will test the VLANS tomorrow.

I guess it hasn't been pushed to the trunk yet.

I know MCWRT is old and obsolete i had been running that for several months. For the past two weeks i have been running various builds of CC trunk and couldnt figure out why my AC wifi was slow.
I decided to flash MCWRT again and right away my AC wifi is atleast 60% faster while connected at the same link rate to the router as CC does. I've done several speed tests to confirm. MCWRT's wifi is still better performing than CC even with the new drivers.

I found the way to connect ntfs drive. There should have been one more package set called ntfs-3g installed.

okay thank you - i just had a look on kernel 4.0 rc6 and couldn't find it, is it only available on kernel 3.18.10 ?

if you have time could you compile a 3.18.10 firmware (similar to the 4.0 rc6 you did for me) but with ntfs-3g

i thought i could download the latest snapshot and just install a couple of packages and i'd be ready to go, but there wasn't any mount points or network shares, i was hopelessly lost.

Edit --
3 days and change. WAN freeze. Wireless stays up, no WAN access. LAN access appears to remain functional.
Saw the same happen with last two Kaloz images and a distant trunk or two.
