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!BEST ALL-ROUND DD-WRT FIRMWARE(S) for G450Hr23919

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
