Re: sam's firmware collections for TP-Link WR703N

@sam or anyone else:

R/W performance on NFS ? MB/s ?

Re: sam's firmware collections for TP-Link WR703N

@Sam
received my 703n today and the setup was a breeze. Pretty much blindly followed your instructions and it worked like a charm. Awesome job on the firmware!

Trying to troubleshoot an issue unrelated to the firmware. Looking for your linux audio expertise here. Now my setup has mpd running on x86 with local alsa and openwrt-pulseaudio outputs. I see that the lead-lag is random. sometimes alsa lags, which is a little weird. Any idea how I can rectify this.

Re: sam's firmware collections for TP-Link WR703N

@s7mx1
I am looking forward your next release.But I would very much appreciate it if you release the pulseaudio package with correct config include usbaudio.
Because I want install 703n to my wifi-car with UVC or 301 camera and stream audio function.

We all know the 703n has just 4M rom,which is so small for those softwares.
So I intend to boot my 703n from a tf card.I still cannot understand how your pulseaudio work...
When I flashed other trunk firmware from http://downloads.openwrt.org/snapshots/trunk/ar71xx/ with Luci webgui and opkg install pulseaudio-daemon kmod-usb-audio,the pulse seems unload anything,no sinks,no modules,even it cannot run...
Unless I input command pulseaudio -nC,entered the command line mode,there is a module-CLI loaded

Now I can stream audio from Windows box to 703n,of course 703n with your Pulseaudio Firmware.

Re: sam's firmware collections for TP-Link WR703N

Hi Sam! Is it possible to add a print service into the NAS (network attached storage) firmware? I have only one WR703N, but I don't want to flash the different firmware to realise the different applications. Thanks!

Hi cncaihua, thanks for your response. I am a beginner for openwrt. So what is the minimum space to add a print service?

The wifi chip inside WR703N is quite good and it's only being let down by the wifi antenna printed on the PCB. You need to adjust the position of WR703N to get the best reception. If you have some old wifi router lying around you can rip the antenna and solder it on WR703N which should give a boot to the wifi performance. I have seen other people installed SMA  (detachable) antenna on WR703N.

Hi Sam, I don't suppose you could elaborate a little on the replacement antenna or post some links?

A print service needs more than 2MBytes space. It seems that there is no space to add a print service indeed. Okey, I have to drop my idea. Thank you all the same!

Re: sam's firmware collections for TP-Link WR703N

Hi guys,

I managed to squeeze more exciting stuff into a shiny new release The Big Squeeze. Changes can be found on the first post.

I urge anyone using the nas firmware to upgrade. If you are using pulseaudio firmware and you don't mind missing out the easy to use pulseaudio status page and among other things then you can skip the upgrade.

Please be aware that wifi AP ssid/key has been updated, so is the shortened hostname. Please revisit the 1st, 2nd and 3rd post before upgrade.

Now both the firmware has the ability to extend storage either via usb hard disk or network file system. The next step for me is to work out a way to run software from those 'unlimited' storage. I am feeling there is not much room for me to squeeze inside the 4MB firmware and if new features need to be added this is the only way forward.

Enjoy your early new year present!

Sam

The nfs kernel server inside the new nas firmware can do 9MB/s read and 6.5MB/s write. The write speed is likely limited by the weak cpu inside WR703N.

I managed to squeeze usb printer driver and software (p910nd) on both of firmwares. Just visit the 1st and 2nd post and give the new firmware a try.

All you need to do is to plug in your printer and configure your client. Please follow the configuration part 2 of the excellent wiki page here.

Personally I have not tried so let me know how it goes.

Hi Sam, Your new CF sounds good, I use an ext. memory stick to run packages off, have a look at this wiki page : http://wiki.openwrt.org/doc/techref/opkg#installation.destinations
I mount my memory stick on startup using fstab, and then export the $PATH and $LD_LIBRARY_PATH variables in rc.local, if the memory stick isn't present, it doesn't matter.

Hope that puts you on the way of integrating ext. memory support.

Thanks for the info and will look into it.
I did a bit preliminary work on it. The variables are already in place in profile and there is a half baked script lying around somewhere in the pulseaudio firmware wink

Re: sam's firmware collections for TP-Link WR703N

hello. awesome firmware by the way. but i managed to mess it up again haha.

i installed the latest nas firmware and the following happened.

so i messed around with the wifi network part and i dont see the wifi signal aymore.. its set as a client  big_smile
the lan is also disabled by defaults!? i noticed it was disabled on first boot.
i tried to set static ip it recognizes that its an open wrt router but cannot go into webif.
i can telnet to it. but it seems like everything is a system file and cannot be modified.
i tried to set the passwd to enable ssh but apparently cannot change the setting because its a read only system file.


question....
is there a way to reset this router to defaults? by pressing the reset button ?
is there a way to change the setting of the router by command?


does anyone have any ideas?

@faramisimo

If you messed up the wifi client setting then the wifi AP will disappear all together since the AP is switching channels rapidly.  The ethernet port of the nas firmware is default to a wan port hence you need to connect it to a router. Nothing will happen if you try to connect it to your pc straight.

If you are able to enter fail safe mode and want to change settings or reset to default you can follow this  reference: http://wiki.openwrt.org/doc/howto/generic.failsafe.

Basically you log into the router via telnet and then issue the following command:

mount_root

At that point you will be able to modify any settings by hand but if you prefer to reset them to defaults you can do so by

mtd -r erase rootfs_data
reboot -f

I am pretty much assuming your pulseaudio firmware supports wifi. Tell me if I am way off base there. I don’t have a lot of confidence on the WR703N wifi chipset and have a feeling pulseaudio streaming would be glitchy as I have a weak signal where I need the speakers. Also there is the issue of network saturation with raw audio streaming.

So it looks like a choice between mpd + alsa (if it is small enough) where it would be a stand alone wifi player _or_ a pulseaudio player with probably choppy music, but networked and in sync with my main wired speakers. 

Am a little worried about tinkering with my nas (raid) as it is my main repository for all the important docs and backups.

The other alternative is running mpd + pulseaudio on 2 Raspberries pi, one replacing my current x86 setup and another with wifi card and remote speakers. So raspi vs WR703N, raspi is more expensive by $13 +  wificard, but looks like it will give me the ability to switch between standalone mode and synchronized mode. I am raring to try pulseaudio on WR703N first in any case.

@Generalenthu

Hope you are enjoying your music powered by openwrt. Just to let you know what I have been working on these day. I am currently setting up mpd and pulseaudio on the same WR703N. This is achieved by installing mpd ( and mp3 files of course)  on the nfs share. What I can say is it has no problem at playing back mp3 files which is being re-sampled by mpd from 44.1k to 48K and then streamed back to pulseaudio locally (hardware only capable of 48K) for playback.  The CPU usage is about 35% during playback.

It looks like you can retire your laptop soon and replace it by one WR703N + your NAS. The above test is done locally however I don't see any problem for mpd to stream to any pulseaudio server on the network.

it reboots after erasing rootfs_data and im back to the same thing...
i try passwd to change password it only works after mount_root command but i am still getting refused connection in winscp.

how can i change the settings manually using telnet? .  let me know if you have any tips for me on how to somehow restore connectivity to the router.

ok i think this is the end of it for this router. i typed in "mtd -r erase rootfs" now its just a solid blue light no failsafe nothing..

@faramisimo
The error you saw after executing is from this file /lib/preinit/50_determine_usb_root which is used to mount usb disk as rootfs. This will not stop you from setting up jffs2 user data partition where all your settings are saved. If you watch carefully it says "switching to jffs2" which means it managed to mount the rootfs_data partition as jffs2. You were also able to modify files at that point.

The "mtd -r erase rootfs_data" is to erase all user modified data i.e. reset to default and I don't think you have encountered any problem at all.

This leaves to either you did not attach WR703N back to the router when it boots or your pc is bit lazy at holding the dns cache. You should at least try using the ip address or check the "attached clients" in your router before doing the really totally totally devastating erasing rootfs command.

Now your router is screaming because of an empty rootfs and if you attach the ttl (serial) console you will see  the kernel panic message.

The only option left for you is to open the case and attach the ttl console and then tftp flashing the router. If you have not flashed openwrt image using ttl console then you better ask if someone nearby can help you as this involves a lot efforts. You can try the forum or IRC channel.

Hope this teaches you a lesson to be patient and good luck to your WR703N.

hi thanks for the reply. yes i am well aware of my impatience and what i've done.  i did notice that switching to jffs2 message and the fact that i was able to read write but i was bothered by the fact that nothing changed after the data wipe. the wifi wasnt on. pc wouldnt catch an ip and it wouldnt show under connected clients in the router. i have connected it and messed around with it for quite a bit of time actually. this is when i got bored and wiped it big_smile haha. yes i am well aware of what i've done. i am not sure why i do these things.

thanks for taking the time to reply to my post... and thanks for the info.

I opened mine up the other day and soldered up the serial console (not because my router's bricked, but because I want to interface it with a microcontroller to control and LCD among other things). I'd suggest being patient when you're soldering as the pads really are minuscule, I used enameled copper wire (and scraped the enamel off, then tinned a short amount), use the finest iron tip you have (I just about managed with a 1mm tip, which is crazy, because it was about twice the size of the pad -- not recommended!). Good luck, it's a lot of fun. I haven't been able to get anything meaningful coming up when I try and use 'screen' to watch uboot, it's all gibberish, I'm waiting for my USB to TTL adapter to come before I try anything (I'm using a USB to RS232 at the moment, I think it's gibberish cause RS232 uses inverted logic)
