@Kong:

Almost 24h since the last reboot:

The signal seems to maintain the "jumpy" state;
Link speed stays at 144Mbps;
It drops the wifi connection regularly.

There is any way to test a different wifi driver without flashing an entirely new firmware build?

Thanks.

@Iqbal,

@Iqbal,

latest stable minidlna 1.0.22

@ReDaLeRt,

no since the code is directly compiled into the kernel. But since BrainsSlayer already added portions of the broadcom driver there should be a new wireless core soon.

Another issue. I'm just testing a new DNS server route and I figured that I get almost 18% of ping loss through wifi but not if executed (simultaneously) by telnet on router.

Weird?

Thanks.

Well sometimes shit happens:-)

2 weeks ago I had big problems surfing the web with my laptop, I logged packages with wireshark and saw lots of tcp retransmissions, first I blamed the router, but since I had no problems with another wireless client I looked at my laptop and after a few hours of playing around I replaced the wireless driver with a new one and since then it has been fine again.

No idea why this shit happened, the old wireless driver worked for over a year.

wabe said: Can anyone give

wabe said: Can anyone give advice on how to enable php_zip support in Optware? I'm trying to get 'Owncloud' a dropbox like service to run on my RT-N16. Almost there but need zip support in php. In theory it's easy just add the line 'extension=zip.so' in php.ini but the problem is that this module is not included in OTRW. Does anyone know how to get it?? @Kong: Since you've been working on the Optware packages any chance of getting a php-upgrade with this extension included?

If I have some spare time I can look at it.

Hi,

Before going further on upgrading my 4965AGN driver, I did a ping test with my Samsung Galaxy S over HDSPA and Wifi. No ping loss at all.

After upgrading the wifi card driver the issue remains. WTF? :-/

Thank you in advance.

@ Dark_Shadow

Which version? I like the older my page script with the bandwith monitor shown above. Is there an update bandwidth monitor script that will still work with that version of my page?

OK Thanks.  I wasn't sure because typing "minidlna -V" didn't return anything.

I spent the whole day yesterday playing with minidlna on this new build.  I used "opkg install minidlna" and it did install a new version (-V worked btw), but when I ran it it wouldn't show itself on my network with out the -d (debug mode) option.  Also, it seemed to have major issues rebuilding its database.  Also, after I installed it, it broke my transmission-daemon.  So basically it completely buggered everthing up, and I'm too much of a linux noob to know how to fix it.  I ended up reformatting and reinstalling to get things working again.

I did, however, determine that the version i downloaded adds at least one additional feature to my tv - the ability to resume playback from where i left off (bookmarks).  Also, the log file reports a different version of sqlite on startup.  So it *seems* like the version included in your build is not the most recent.  Is this something you'd be able to look into?

In the meantime, I'm going to keep searching for answers.

Thanks for the great work with this firmware.

EDIT (3 hours later):  Scratch that.  I just discovered that the bookmarks do work with your included version of minidlna.  So everything is good.  Thanks again.

Tried that version, it seems to only work with newer mypage script and refuses to work properly with the mypage builds from last year.

Hello King Kong,

Hello King Kong,
I installed r17940-ASUS-RTN16-kingkong-nv32k-broadcom.bin on RTN16.
Here are my results.
1) Wireless Connection was dropping and I found channel 3 was not used in my area by others and after adding channel 3. I am getting 100+ Mbps. The least I saw was 36. I have used others versions and found that I get only 5.5Mbps.
Was getting 100+ only by using your mod.

2) I have the left and right attena at 45degree and center at 90degree.

3) This is for other users.
My settings : AP, Mixed mode, 20MHz.
My Wireless Security : WPA2 Personal, TKIP+AES. Key Interval 3600.

I havent changed anything other than the password and Wireless and Wireless Security.

Thanks for your wonderful firmware.
FINALLY I HAVE 100+ MB WIRELESS SPEED. YAHOOOOOOOOOO.
I will keep this version and I will not upgrade to anything new :)

Tnxs Venkat for your post! I have been waiting to upgrade my RT-N16 w/DD-WRT 15926 for a year and your report makes me think it's pretty safe to do so now.

@Kong:

You have lots of TX errors on the WebAdmin? I have more than 600 in just 3 days. :-/

I changed to every channel and re-adjusted the 3 antennas. No luck at all.

Thank you in advance.

Does this work on Belkin

Does this work on Belkin F7D3302? The processor is the same as F7D4302; but the wireless NIC is different.

@Kong:

I'm getting very fustrated. I'm running some bidirectional throughput tests with iperf (router wireless client) instead of samba, and results are:

iperf.exe -c xxx.xxx.xxx.1 -w 5M -t 30 -r
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 5.00 MByte
------------------------------------------------------------

------------------------------------------------------------
[156] local xxx.xxx.xxx.6 port 56531 connected with xxx.xxx.xxx.1 port 5001
[ ID] Interval Transfer Bandwidth
[156] 0.0-32.0 sec 96.3 MBytes 25.3 Mbits/sec
[128] local 192.168.10.6 port 5001 connected with 192.168.10.1 port 34293
[ ID] Interval Transfer Bandwidth
[128] 0.0-30.0 sec 75.6 MBytes 21.1 Mbits/sec

Do you have any ideas about this low wifi performance? Does the router getting limited to "G mode bandwidth" by some settings?

I'm testing with a Intel 4965AGN and Intel 6200-N clients. Both with the same results.

There are just a huge sum of problems reported by now:

TX errors;
Jumpy wifi signal;
Low throughput on wifi;
Low link speed sync.

Thanks.

Hi,

Hi,

I'm conducting some throughput tests.

Setup:

RT-N16 (17940M Kingkong) (NG-Mixed + WPA2 Personal @ 20MHz width channel + ACK Timming = 0 + Frame Burst ON).

Iperf running two servers (RT-N16 and another on one client). iperf -c xxx.xxx.xxx.xxx -w 10M -t 60 -P 4

Client 1: Intel 6200-N + Realtek Gigabit LAN

Client 2: Realtek Gigabit LAN

Results:

Router >> LAN --> avg: 105Mbit/sec

Router >> WLAN --> avg: 28Mbit/sec

LAN >> LAN --> avg: 711 Mbits/sec

It gets curious:

LAN >> WLAN --> avg: 40.6 Mbits/sec

BUT, sometimes it raises up to a steady 70Mbit/sec burst (99.9% of a 60sec run), without any changes even on neighbour networks at 2.4GHz. I'm testing this out of any known source of interference non 802.11.

The reception signal on WLAN client remained very stable on this tests. (signal: -40dB & noise: -88dB)

One more thing: I can not get a link speed higher than 144Mbps even with 40 MHz channel on the router. It simply just uses ONE 20 MHz width channel. I don't understand why (maybe Broadcom wifi driver bug?!).

Thanks.

Not sure how the latest intel driver sets this, but my intel adapters did only run in 20Mhz mode until I reconfigured them to operate in 40Mhz mode:-)

Hi,

You miss undertood me. With inSSIDer I can see neighbor networks using 40 MHz. But I can't see mine using them! It stays with 20MHz width!

Thanks.

Hi,

Hi,

@MadRocker:

I have more than 40 dB of SNR. I think, and some of the tests above proved it, is more than enough to get higher than 50Mbps of real throughput. Increasing the output to 25mW* from 17mW, I just get more 1 dB of SNR (average). I think this isn't a SNR problem, but firmware/wifi driver issues.

I repeated the tests at 3 a.m. GMT, with 99.9% of my very old neighbours sleeping. (most of then have 80 years old and increasing :-) ) Similar results. I'm buying an AirView2 on the next few weeks. It's pending on the seller to report me the stock.

---

I did setup my wifi card like you said, but the router does NOT uses an additional channel to obtain a 40MHz bandwidth. This is visible using the inSSIDer software, comparing my network configured to 40MHz with some of my neighbours that installed 802.11n routers operating with 40MHz channels. It simply stays with one 20MHz channel. Even with a cold boot.

Flashed back to 15508M Eko, using the same settings, it jumps to 40 MHz bandwidth.

I love this 17940M, but the wifi support on my equipment is a mess. I'm sorry, but this is the truth. I'm using 15508M since I bought the router at November 2010 without any issues on wifi. But it is simply older enough to cause me some other compatibility and support problems (like VLANs).

Thanks.

*I'm not sure that is safe to go further more than 25mW. It heats a lot, even with pure cooper heatsinks installed. At some weeks ago I did a study to put it on watercooling, but is expensive. :-)

PS: I'm tired and my english sucks, so forgive me. :)

If I find the time, I'll test

If I find the time, I'll test 40Mhz mode. With the older driver I tested it and had 270Mbps.

I was just thinking to check if it is possible to include the old wireless core from the 15000 builds but keeping the latest ethernet driver.

@Kong: I'm available to test

@Kong: I'm available to test any (safe) build on my router.I want a solution and I can contribute to it. There is any way to get the wifi driver loading by modules? (like most of general drivers on linux)

Could it be possible that I may have an older version of 4716 SoC?

I'm counting the €uros to buy a netgear wndr4500 just for testing/benchmark proposes against mine RT-N16. Maybe Santa Claus could help on it. ^^

Thanks.

Hi,

Hi,

I tested again the 40MHz channels and it worked. But, even with the laptop over the router's antennas it gaves only a link speed of 274Mbps. eheh

All 3 clients (6200-N, SGS and 4965AGN) connected but only the first two had successful usage. 4965AGN was horribly slow (10 KB/s - wt*?!).

It didn't give any more throughput over the benchmarks posted earlier with 20MHz channel.

New wireless setup (ACK Timming = 200m + Frame Burst = off + TX power @ "25" + Bluetooth coexistance mode = Preemption).

Best regards,

Well, well yesterday signals

Well, well yesterday signals were dropping again.

Thus I'll definitely ship older drivers again with the next builds for single radio units.

@Kong you should be able to have both driver if they are modules and then the user can load / unload the wifi module or maybe have a script that load driver1 or driver2 as modules and restart the whole wifi networking cascade.

This works well with regular opensource drivers that are bundled with the kernel. But with these drivers it's not quite that easy. You have a binary driver and a kernel wrapper and a userspace tool to control ther driver. Their interfaces need to match.

Hi,

There is any way to compile both drivers into kernel but run only one at once through a nvram variable value?

Hi everyone,

Hi everyone,

Petty question here,
My RT-N16's wan light blinks constantly, even when there is no data incoming/outgoing, I have disabled wan from setup, reflashed stock firmware and back, but it would not stop, as I plug the cable in the wan port it starts flashing, I don't think it used to do that before. Is it ok to leave it like that, its a new unit just 2 weeks old.

Thanks.

Thanks @kt_haddock,

Thanks @kt_haddock,
Ya, if I unplug the cable it stops dancing. I am dialing pppoe from the router and I clearly don't remember but two three days back the wan led would be steady when there was no data flow. Also when it flashes constantly the modem wan light doesn't blinks, it blinks only during data flow. Any ways my b.p. has leveled out from your input.

Thanks

Nope not possible, but I just opened a ticket in order to get the latest wireless core into repository, since BS already includes it in his builds.
