Buffalo WZR-HP-G450H Post 20025 Firmware Solution

[JacobD84]

Hi all,

I have for sometime now, as many others on here it appears, had issues with the 20025 DD-WRT firmware for the WZR-HP-G450H. My Samba doesn't work, there's problems with DNLA and connecting devices, as well as dropped connections and a whole host of other issues.

Thankfully there is an official DD-WRT community build now available on the DD-WRT ftp site that has finally fixed all my issues with the Buffalo version.

NEWEST (Tested & Stable On EU/UK and US Router):
r27805 ftp://ftp.dd-wrt.com/betas/2015/09-11-2015-r27805/buffalo_wzr_hp_g450h/
For PCB Rev1 and higher only! Using with older PCB revisions WILL brick your router (Thanks for report Harlekin)

r27240 ftp://ftp.dd-wrt.com/betas/2015/06-05-2015-r27240/buffalo_wzr_hp_g450h/
For ALL PCB Revisions including those earlier than 1! (File-size limit)

UPDATE (September 2015):
PLEASE CONSIDER r27240 AS THE LAST FULLY TESTED VERSION FOR THE Rev0 PCB G450H (Open your router and look for PCB label if unsure - Remember this, as with altering firmware WILL invalidate your Buffalo Warranty and Support!)
THERE WILL BE NO MORE RELEASES FOR Rev0 PCBs AS THE >26MB BARRIER CONFIRMED BY HARLEKIN PREVENTS UPDATES
DO NOT UPDATE Rev0 G450H's to higher than r27240 - You WILL brick your router!

UPDATE 2 (September 2015):
PLEASE CONSIDER r27805 AS THE LAST FULLY TESTED VERSION FOR THE Rev1 PCB G450H (Open your router and look for PCB label if unsure - Remember this, as with altering firmware WILL invalidate your Buffalo Warranty and Support!)
THERE WILL BE NO MORE RELEASES FOR Rev1 PCBs AS THERE APPEARS TO BE A ~27MB BARRIER PREVENTING UPDATES
DO NOT UPDATE Rev1 G450H's to higher than r27805 - You WILL brick your router!

Please note, this is a DD-WRT build, not a Bufallo certified DD-WRT build, but if your having issues with the 20025 firmware then the upgrade is probably worth a shot for you in the absence of any official Buffalo revisions.

If you do not have issues, don't risk breaking something that doesn't need fixing by updating ;)

I have used the wzr_hp_g450h-dd-wrt-webupgrade-MULTI.bin firmware in my update BTW, the wzr_hp_g450h-factory-to-ddwrt.bin i have not tested!

To upgrade, download the file from the FTP, then using the Buffalo DD-WRT GUI head to Administration, Firmware Upgrade and select the file on your PC. I recommend resetting all settings to their factory defaults on upgrade.

Hope this is of help to all of you :)

Hey Buffalo,

I am having the same problems with 20025.

This firmware is over a year old.  What gives?

Are you ever going to address these problems?

Or, maybe your business model is based on selling hardware -- and then not supporting it.

Many of the customers who bought this product did so specifically because of DD-WRT.

Look, I get it -- broken firmware happens. 

But taking over a year to fix the problems is a good reason to never buy products from your company again.

installed the (alternate) firmware from this link :

http://www.dd-wrt.com/dd-wrtv2/down.php?path=downloads%2Fothers%2Feko%2FBrainSlayer-V24-preSP2%2F2013%2F07-24-2013-r22118%2Fbuffalo_wzr_hp_g450h/

SAMBA works ... :D

Thanks JacobD84

[mailman]

This one looks live the best firmware ever released for this crappy router.
Its place is the garbage btw.

[Mkorofi]

@Jacob:

can you please advise me how to change from the "user Friendly software" to the software you have advised?

i have tried to use the tftp2 client, but i have not succeeded.

any advice would be greatly appreciated.

Thank you.

Imran

A new update is available here:

ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2014/01-10-2014-r23320-fix/buffalo_wzr_hp_g450h/

See first post for disclaimer; new version is r23320!

Imran, you could try the factory to dd-wrt bin file? Not able to test myself sadly

[JacobD84]

UPDATE: All new builds have now been moved to another FTP directory found here:

ftp://dd-wrt.com/betas/

At time of writing, latest version for the WZR-HP-G450H is r23598 HERE:
ftp://dd-wrt.com/betas/2014/02-19-2014-r23598/buffalo_wzr_hp_g450h/

[mcbride0786]

r23598 is so bad so bad !!!!!
:(( i really regret,
the router now is working so bad with this new firmware.
The signal is so weak, keeps dropping every 10-15 minutes, and sooooooooooooooo slow internet transfer rate.
any advise ?
How can i get it back to 24sp2 20025, i know it bad but it even so much better than this crappy firmware.
M,

[JacobD84]

Hi mcbride, sorry to hear you are having issues with r23598...

If it's signal related try changing the following under Wireless->Basic Settings->Advanced Settings Tick Box->

Make the following options in the attached image saved, applied, and reboot the router under Administration->Scroll to bottom-Reboot Router

If all else fails revert to an earlier firmware from the list of revisions at ftp://dd-wrt.com/betas/ ... Simply head Administration->Firmware Upgrade->Browse and select the bin file...

JCB

[JacobD84]

[AMJ966]

dear JacobD84
did you manage to run HMA open vpn with your Buffalo?
I have the same router and I couldn't figure out how to do so.

[JacobD84]

Hi AMJ966,

I do not use VPN on this router, however, there is some good stuff on HMA O-VPN here:

Hope this links to what you need :)

[davisdmg2]

I have to say, the last version23720 is reallt good. Really stable. I lost a bit of wifi signal, but I won a lot of stability!

[mcbride0786]

Thanks a lot, mine works really well with this latest FW . :) well done
