Buffalo's rebranded DD-WRT build 14512 and whr-hp-gn is flaky. Installed it two days ago. Crashed and rebooted a day ago. Then, it crashed and rebooted 40 minutes ago.

I know is it going crash within ~1 hour because the "Time" field in the web browser says:

WAN port is disabled.
DHCPD is disabled.
WEP is enabled.
Static IP == 192.168.1.5
I.E. It's a router ONLY.
reason for this is that the standard dd-wrt builds and buffalo dd-wrt rebrands are exactly the same other than the interface colours.
and we all know that dd-wrt is unstable on atheros 9xxx cpus due to dd-wrt using an outdated madwifi driver and not atheros's official ath9k driver,
for stability with these buffalo routers your going to have to stick to the regular firmware. if you want professional level features along with reliability and performance then your going to have to purchase pro hardware from the likes of ubiquiti / senao etc.
From Admin: The MadWifi driver is for Atheros A/B/G chipsets only. In DD-WRT, the latest Atheros carrier driver with many fixes is used. ath9k is not an official driver from Atheros, but an open-source project, that DD-WRT also supports with significant development resources.
Crashed again:

My Asus RT-N16 is FINE running DD-WRT v24-sp2 (12/18/09) big - build 13491M NEWD-2 K2.6 Eko. Uptime 21 days (due to a power failure). What is the story with Buffalo routers???
router-rkkda2 is a Perl program:
#!/usr/bin/perl
use Net::Telnet ();
$t = new Net::Telnet (Timeout => 10,
Prompt => '/.*~# /');
$t->open("192.168.1.5");
$t->login("root", "password");
@lines = $t->cmd("uptime");
print @lines;
WEP is just about completely useless for security as you (probably must) know.

If there are others having this issue, please post your exact router, (in this thread) the activities before the crash, and your system logs. We haven't been able to reproduce this in our labs, so the more info, the faster we can work on this.

I get the same problem. Notably it starts giving major packetloss until the router freezes up. We're talking 30-75% packetloss when the HTTPD starts having problems.
I've also noticed that establishing a SSH connection seems to instigate the problem almost immediately.
#!/usr/bin/perluse Net::Telnet ();$t = new Net::Telnet (Timeout => 10, Prompt => '/.*~# /');$t->open("192.168.1.5");$t->login("root", "PASSWORD");@lines = $t->cmd("uptime");print @lines;@lines = $t->cmd("killall httpd");print @lines;@lines = $t->cmd("httpd -p 80");print @lines;I run this from cron on my main computer right now as a workaround.$ crontab -l | grep rkkda20 0,4,8,12,16,20 * * * router-rkkda2 >/dev/null
I don't know much about using cron, is that basically running the script every 4 hours?
Yes. Every 4 hours.
About HTTPD: the HTTPD issue is relevant if you have a status page open (that pulls information from the router) over > 1day
does everyone here that is experiencing the HTTPD issue, have a status page open, if not, please give details about your other settings.
well, what a surprise. I'm glad to see a BT answer.
It turns out that by using actual DDWRT firmware instead of your own, I dont' get a HTTPD leak. I appreciate ackowledgement of it, but a fix would have been better. I used the brainslayer v24 -http://www.dd-wrt.com/site/support/other-downloads?path=others%2Feko%2FBrainSlayer-V24-preSP2%2F06-30-10-r14684%2Fbuffalo_whr_hp_gn%2F and it worked - no more HTTPD leaks, no more memory leaks at all.
I've gotten the HTTPD link with and without having a status window open. Also, it's noted that even if you close the status window and reopen it later, the memory is still not reclaimed. Maybe it's a separate memory leak.
Also, for the Drmemory, When I play team fortress 2 and I view a server's information using the buffalo DDWRT firmware, the router will freeze when I view the server information. This is with wireless G along with WPA2-PSK, dnsmasq/dhcpmasq on and sshd on. Doesn't matter if any of these are on or off, it still happens, and I've tested with all of those features on or off including dmz. No servers being hosted. 100% reproducible. Router will completely freeze and 192.168.11.1 will not respond. The wireless light, network light, and status light will all be solid, while the active ethernet port lights will blink constantly.
Since using the brainslayer custom DDWRT firmware listed above, no issues. Of course I'd prefer to be able to use official buffalo firmware instead but eh. Sorry fellas. Maybe you want to compare what that specific ddwrt firmware does to the one offered by buffalotech?
DD-WRT has promised a new revision coming to the Buffalotech DD-WRT that will address the HTTPD issue.
I get the same issue. with 14512 from the buffalo site, I get ~20% packet loss on every IP past the router's WAN IP. With my old non-buffalo-non-dd-wrt router, I get 0%.
This is with an uptime of < 1 hour and no hits to the web frontend.
I'll see if I can get an update.
i was told by buffalo staff that the when the wzr-hp-g300nh dd-wrt firmware is released in september the build revision will be used as the update for the whr-hp-gn and whr-hp-g300n routers too. so all 3 dd-wrt routers will be running the same build versions and future updates are to be released for all 3 routers at the same/similar time.

Build 14998: Works good! Thanks!
Anybody else having trouble upgrading to the new 14998?
I get an immediate "upgrade failed" trying to update from 14512.
The extracted filename I have is a little different from what is posted above by the way - I have "whrhpg300n-pro-v24sp2-14998" which 'sounds like the right thing' but the filename isn't exactly what rickrich is listing.
yet again how nice Buffalo?
which BT site did you use for download.
BTW - profanity does the exact opposite than your intent to be noticed - it usually entices the mods to wait a few days in answering a post.
smileyvery-happy:
The world would be incredibly boring without colorful language. Just a buncha dorks and jesus freaks walkin around being polite. Who needs that?
and which BT site did you download from?
can someone post where the ddwrt revision mentioned here is located for download .. also is there any update on when the new firmware from buffalo will release .. i have just setup a school with 4 whr-hp-gn routers and the http issue was a major disappointment .. even without logging on to the status page the whole network ( in wds mode ) was suffering major performance issues at given periods during the day ( all due to httpd leak no doubt ) .. some info from buffalo on when the new ddwrt firmware is to be integrated into their friendly release of the firmware would be greatly appreciated .. i dont think i would recommend this hardware again if theres no resolution soon .. its a shame but its the reality of the situation and its also not being profane .. i hope someone responds to this :robotindifferent:
WHR-HP-GN Buffalotech USA DDWRT is at www.buffalotech.com/support/downloads; select your product, then download the FW.
Or, go to WHR-HP-GN BT/DDWRT FW V24-SP2 build 14998
This link is good now, but after the next refresh of DDWRT, the link may change.
