You can also repeat 3 times! It's true

The last time I rebuilt firmware for my wdr4900 in late April it was r40567 revision, and I believe it works stable enough for me.
At least I can't remember if there were any noticeable wifi dropouts or hangs with that version.

After debricking my router at the weekend i loaded r41360 from 28/06/14 and haven't had any problems.

I don't run 40MHz channels on 2.4GHz and, although i do set 5GHz to use it, i don't have any devices connecting over 5GHz.

Set 40MHz on 2.4GHz and verify it.

r39430 is known as stable. Others may work for some and fail for others.
I recommend to try first the current Trunk, and if it doesn't work properly, have a second chance with that custom build

WDR4900v1:
r40768 works with LuCl and 802.11n 2,4 GHz Wifi like a charm.
Stable for about 2 Months. Have not tested 5GHz and 11ac.

r41534 (added IPv6 via 6in4 HE Tunnel) and experienced no problems, running two days now.

Many Thanks for all the Support and Doku Stuff.

EDIT: I just read fcecamors post:

I have the same "20Mhz" Bandwidth and  "TX power offset: none  ** Frequency offset: none /unknown" output from iwinfo. Although 20 Mhz on 5 Ghz 802.11n.

But I don't had any connection issues nor have seen in dmsg /logread :
ath: phy1: Failed to stop TX DMA, queues=0x004!

Because you are using 20MHz instead of 40MHz.

Hi @ all
i´m currently running r39430 on my WDR4900, long in short i am not able to use luci with SSL. i reinstalled uhttpd-mod-tls and luci-ssl, in the "default" uhttpd config listen_https is defined. any hints how i got it to work?

Thanks in advance
ralto

With latest trunk it seem to work

you mean openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-factory.bin from  Index of /snapshots/trunk/mpc85xx/?

Yes, but HT40 is broken

Thanks is up and running, but now i have a few problems regarding dhcp and dns. i am not able to use static ips (20 reservations) in dnsmasq. anytime i load my config dhcp stops working and local dns isn't working. i have done the whole config twice and third like documented in the config file and using the gui.

Thank you for compiling this truck, as a newbie to OpenWRT, I have successfully converted my router.

However, when trying to install the USB storage modules and others, it fails with the following errors.

Any suggestions for a stable installation?

If I have understand correctly opkg will try to install newest packages and those does not mach on kernel on r39430 which is older. You need to try newest trunk, install packages for it and hope it is stable.

I agree, however, the r39430 trunk has been recommended as the most stable release compared to recent builds.

For this reason, there maybe a method to obtain older packages, to produce a more stable environment than run recent builds with known bugs.

You would have to build the modules yourself. The Openwrt servers don't keep old versions of trunk packages.

Ah, so adding additional modules to more stable early revisions is going to be a lot more challenging for newbie's to OpenWRT.

Is there a well documented process for this?

Other than the 40MHz issue on both frequencies, resolved by running 20Mhz, what other major issues would prevent the majority running the latest truck?

Additional modules for official "stable" builds - i.e. Attitude Adjustment 12.09, Backfire, etc. are fine as those are defined as stable.

Trunk is by it's nature unstable and experimental, and you shouldn't count on it existing at all tomorrow let alone in the same/compatible state. Unfortunately it means if you need to use a development build *and* need to add optional modules, you have to keep it yourself.

What you could do (too late now) is to mirror a snapshot of Openwrt's snapshot builds at a certain point in time and host it yourself.

If you ask me personally, newbies shouldn't really be messing with unstable/development builds of Openwrt at all, but I admit there's a lot of devices on which development builds are the only ones that will work.

The build process is however, quite well documented on the wiki:

http://wiki.openwrt.org/doc/howto/build

It's very detailed and covers every step of the process from beginning to end. It's not an easy process but if you follow the instructions you should be fine.

It's a bit inefficient making everyone build their own copy, but short of someone mirroring the Openwrt repository or running their own buildbot, the only other thing you could do is try convince the Openwrt team to maintain copies of every snapshot build ever, which is quite unlikely...

I agree, running an official stable release would be best practice for a newbie to OpenWRT.

However, for hardware revision 1.3, the WDR4900 Wiki does not list an officially supported version other than a known stable trunks.

https://forum.openwrt.org/viewtopic.php?pid=237869#p237869

Please correct me if I'm wrong, since Attitude Adjustment 12.09 or Backfire does not appear to list mpc85xx, Barrier Breaker 14.07-rc1 appears to be the only listed alternative to the known stable trunk.

isnt there a mpc85xx target in the trunk. doesnt it work for the tP-Link WDR4900?
I am compiling it now and once its done I will post about the results.
if anyone is quicker, please go ahead and write about it :-)

I forgot that our device had 16MB flash! I was used to 4M on my old routers hehe.
I'll compile r39430 with a lot of stuff

Edit
Here it is. Added:

Samba36 client and server
USB storage support
Filesystems: ext4, vfat, ntfs
Native language support: cp437,cp852,iso-8859-1, utf8
Other: fdisk, Luci, ntfs-3g

openwrt-mpc85xx-generic-tl-wdr4900-v1-squashfs-factory.bin

Now we talking about. Does it have pppoe suport?

Hi, I`ve been reading this topic for quite a long time.
Today I finally tried to build r39430 myself. I use the link of dabyd64 to get the trunk folder: " svn co svn://svn.openwrt.org/openwrt/trunk/@r39430 "

I choose the kernel modules I want (I can´t find Luci by the way) and I compile it without errors.
The problem comes when I log into the router, it doesn´t recognize any interface (neither Lan, WAN or WAN6), it just shows : "Collecting data..." Also, when I click on the wifi configuration tab it pops the well known error saying: "Bad Gateway,
The process did not produce any response"

So, basically, I have a router wich does everything except work as a router.
I suppose there must be something that I should also compile but I can't find anywhere what it might be.

Any help would be really appreciated

Thank you very much

I like written_direcon's custom build, but I also need "kmod-bridge" and hfs+ so that's why I'm trying to compile it myself.

I've tried both written_direcon's and dabyd64's custom builds and they work perfectly, so I know it's not a hardware related problem.

Thank you very much again

Hello, WDR4900 is my first router I have installed openwrt on. I have successfully used dabyd64 r39430 above to flash it. Everything seems to work except i don't get Internet thru the router but if I bypass the router it works fine.

Windows network diagnostics says: dns server isn't responding

I have read the wiki for a couple of hours but I can't find any solution.

Does anybody know what the problem might be?
