DD-WRT (Build 14815) for the WNDR3700 is a very nice build and feels stable at the moment.
Once the nature of the posts for the latest build took a turn for the better on this forum, it was just a matter of time before I got amongst it and flashed.
I've stuck with safe settings for now, will tweak soon.
Putting ath0 through it's tests, so far its passing with flying colors, no lag spikes, dropouts, throughput issues, or anything. Stable at 300Mbps in windows and on DD-WRT TX/RX status. Have eMule running while im gaming online with TF2 and my latency is stable, about 1-2ms higher than with ethernet (that can even be considered error margin). TX errors right now is 97 out of 412,785, right on par with the DIR-825 and RX errors is 0 out of 352,741
Great to hear, thanks for updating us. Let us know how the 5GHz fairs as well. Quick question, what card/chipset are you using as a client in your wireless testing?
Also, can you check if you can get over 17dbm on channel 36 in ur reg. domain? If I set my power to 20 or 17, it stays at 17 on channel 36. Anything other than that, 18, 19, 21, 22... and so forth brings the power down to 16. Thanks!
I cap at 17dBm with chan 36 which is matching FCC ID documents here:
Also when I change ath0 to ht20 I cap at am amazing 26dBm, which matches FCC ID listings for 802.11b DSSS. Thats 2Wire output power! Its stable too, no jitter like some routers do when TX is too high (lack of amps from the PS?).
I haven't done much ath1 testing but from what I did so far, by connecting with the WRT610N v2 in repeater mode, its behaving just as good as ath0, range/SNR a bit lower but thats the nature of 5GHz frequencies.
My test equip is:
-DIR-825 (client mode, havn't tried yet)
-WRT610N v2 (repeater aka client mode for Broadcom)
-D-Link DWA-542 2.4GHz PCI wireless card (in my pc) it has a Atheros chip and is 2x2
-iPhone 3GS iOS 3.1.3 (great signal dBm reader)
Continuing to experiment.
EDIT: ath0, ht20 G-Only, 27dBm, iwlist ath0 txpower agrees with GUI. This is nuts, beyond 2Wire output power.
Do you know if it is possible to get the DIR 825 that high since it is almost the same equipment? I would love to get my transmit power up. If only I could find a way to get the 5ghz up a little bit. _________________ DIR-825 Rev B1 / DD-WRT v24-sp2
Router Model
Netgear WNDR3700
Firmware Version
DD-WRT v24-sp2 (06/30/10) std - build 14684
Ive ran into the problem ( only because it keeps accurring ) that sometimes when applying settings the router slips into a weird mode that redirects everything from my routers ip address to another computer hardwired on the network , and it happends randomly with pretty much any setting change . Anyone else encountered this ?
All i have to do is hard reset the router , and the settings go back to normal and the new setting i set is applied, but very strange.
Details:
i have a computer i use as a seed box which has a http server on it usualy hardwired to the 4th port (the only reason i know it dose this). Sometimes when settings are applied,and the dd-wrt web interface refreshes im presented the page being hosted on this see box instead of the router web interface.
Strange enough all traffic is forwarded from the routers defualt ip to this computer (any port). I've tryed to see if mabe the routers ip somehow got changed to a diff one during all this but no luck . it takes a hard reset for the router to go back to normal.
Next time it happens i guess ill scan the whole range and see where the router ended up. Its quit frequent tho ,if its a firmware issue i would assume im not the only one .
Also - small but 1 thing i found . Setting this build up to work with HotSpotsystem.com (embedded)When setup to isolate hotspot users from my home private network . it seems to work perfect with assighing wired ip addresses to the right ip range, But when wireless clients connect its simply lets them have open access to the internet and also assigns them an ip in the range with my home network, instead of the range created for the hotspotsystem traffic (which is probably y they end up with open internet access).
Ive used hotspotsystem before with other dd-wrt routers and not had this problem. With the range of the 3700 one i was hoping to apply it to this router as well. Ive been playing with settings for weeks any suggestions on this ? Or anyone else having a similar issue
By the way: This Build is GREAT .. its really stable other then thoes 2 small issues im having and run great on this router , Getting same range as with stock firmware as well . LOVE dd wrt THANK U FOR GIVING US THIS AWESOME FIRMWARE
Yeah.. but lets see if the bad 2,4GHz reception does appear after some time using this with the WNDR3700. _________________ WRT54GS v1.1 with TOMTAO & SD-Card Mod

DIR-825 won't budge from 18dBm/17dBm even with the same settings, FCC ID documents list it should be maxing at the same TX as the WNDR3700 so it doesn't make sense. _________________ LATEST FIRMWARE(S)

I haven't seen anyone posted about this. But my WNDR3700 upgrade to new built (14815) from the previous built (14684) did not go thru smoothly using the webflash version. I did 30-30-30 reset but did not correct the problem. Has anyone seen this problem? This was not for these particular builts but I have the same problem with the last few builts.
To put the 14815 on, I reflashed back to stock f/w and upgraded using the factory.img version. It's rather tedious so if there is a way around this, it would be great. Thanks for any insight.
I posted about this a few pages back. This has been an issue with the last few firmware releases. There is a ticket open regarding the issue so hopefully it will get resolved soon.
You can try tftping the new firmware on instead of going through the ddwrt->stock->new ddwrt cycle, but I make no guaruntees that it'll work or is safe to do.
It's really hard to brick this router though, you could always put it back into tftp recovery mode by:
1. make sure your pc ip address is in the 192.168.1.0/24 subnet that is not 192.168.1.1 (i.e. 192.168.1.2) and plugged into a lan port on the router
2. turn the router off
3. turn it on and wait until the LAN LEDs turn on
4. as soon as they do press and hold the reset button
5. the power light will blink orange a few times and then start blinking green
6. as soon as you see it blinking green let go of the reset button, it's in tftp recovery mode.
7. type "tftp -i 192.168.1.1 PUT <filename>" into a command prompt from the directory where your flash image is and replace "<filename>" with the name of the file.
8. you should get a dialog saying flash successful
9. wait up to 5 minutes while the router does its thing
That process should always be able to recover the router unless you modify the bootloader (don't).
Ok, I got the 14815 built on my WNDR3700. It looks good only on the 5Ghz band (as good or better than stock). But the 2.4Ghz seems to be as weak as from previous builts. I set Tx ant chain as 1+2+3 with turbo mode on the channel width, everything else was as default. Anyone care to share their setting to max out on the 2.4Ghz for this built? Thanks a lot.
Another thing for this 14815 built, when I used the "apply settings" after a change, it seems to upset the router that the WAN IP was lost. I have to reboot the router to regain the IP.

Good idea, I should have tested it this way. I normally use the gui "tftp" (http://www.dd-wrt.com/dd-wrtv2/downloads/others/tornado/Windows-TFTP/tftp2.exe) instead of the command prompt (I lost my DOS mojo long way back). Thanks for the info, I'll try it when a new built comes out.

Chains for this router is 1+2 for both, not 1+2+3. Change those and report back, did you hard reset and did you ever enable JFFS on the WNDR3700 in it's DD-WRT lifetime? _________________ LATEST FIRMWARE(S)

Someone else reported this problem might be worth opening a support ticket for it.

out of curiosity, why ask this? I never had any problem with JFFS.

I changed to 1+2 for both 2.4 and 5Ghz bands. The result was still as before; super strong 5Ghz but weak 2.4GHz signal. Did both enable/disable JFFS, did not see any improvement. Btw, I have the us wndr3700 version.

I meant was JFFS ever enabled before, not to enable it unless you need it.

Cause for the first few months after DIR-825 became supported there was problems with enabling JFFS that caused corruption in the caldata and other problems, including wireless, even backups of caldata did not correct it until firmware changes from Brainslayer. Something about caldata/JFFS being positioned in the middle of the flash on the router IIRC. I suspected it for a while with the WNDR3700 since some have clear issues and some have none, and the routers are very identical at the hardware level. _________________ LATEST FIRMWARE(S)
