The Australian Buffalo site has posted a new DD-WRT firmware (build 17135) for the above router. I've opnly just installed it (I'm located in Canada). It seems to work, whether it has resolved any of the concerns/issues has yet to be determined.

Also, Buffalo AU have relesed a new version, the same base build, for the WZR-HP-G300NH2 but haven't for the WZR-HP-G300NH, which is a shame.
Can anyone tell me the differences between the WZR-HP-G300NH and the WZR-HP-G300NH2?
Try being the rest of us, where all the other Atheros units got nothing for a month now, still on 16994, someone on Broadcom releases DAILY test builds but refuses to do the same for Atheros, go figure. _________________ LATEST FIRMWARE(S)

Not currently. the CD will not, and there is currently no revert BIN.
maybe if you can tfp it in an unbricking process.

Yeah, this is my first foray into atheros as an AP.
It's weird because they're the top of the market for chip quality and, in client drivers have been solid for as long as i've been using them. (and have supported linux for longer)

Well tried the Alpha firmware. No difference from the Buffalo Shipped version. I did notice that late last night the unit seemed to loose all wifi connectivity. Surprisingly I wasn't upset or even surprised, I've resolved to myself that this unit with DD-WRT is JUNK. This morning I flashed it back to the User Friendly version. One oddity was that it didn't start up with DHCP automatically, so I had to assign a 192.168.11.x address to communicate and configure the unit.
As it stands this is the LAST Buffalo product I'll ever purchase. I'm looking at a Ubiquiti Nanostation Loco M or the Nanostation 2 (it has a RP-SMA connector). Any advice would be appreciated.
Improved authentication support for mobile devices.
Hoping this allows the mobile clients to roam without dropping connections sometimes

[Bug Fix]
fix disconnect issue for Intel Wireless clients
Includes additional fix for many none critical isues.
Yep, some/most intel "N" clients experience intermittent problems connecting at all. Funny, they can go for days without problems, then all the sudden, they have problems and you can't connect for the life of you.
Only solution for complete reliability is to disable "N" in the intel wireless clients (or in the router itself).
I'm gonna try and find this and then do some testing with it.

My issues with an intel client was solved by updating the intel drivers to the latest release (in my case for the intel 51xx) from the Intel site. The drivers on the Dell site were outdated and exhibited some of the aforementioned traits. _________________ WRT54G V1.0, build 14853 VINT mini_USB_FTP, USB mod, pixelserv

FYI, power output maximums change depending on which channel you are on. Channels 5, 6 and 7 on the WZR-HP-AG300H yield the highest dbm. I'm running 19 dbm on mine.
Please also note that the stated dbm is at the radio level and is before amplification and antennae which add significant power.
It is also average power and not peak power. The US law/FCC allows a maximum transmitted power of 30 dbm PEAK. That is roughly speaking ~20 dbm average power. Lower and higher channels are too close to the edge so they need to be throttled down to not go over the maximums allowed below 2400 MHz and above 2483 MHz. As such, center channels allow maximum power.
Again, the indicated power is far from reality on the Buffalo units, but you do need to play around a bit to find the best channel that allows for maximum power.
Finally, 40 MHz mode has higher peak swings than 20 MHz making the maximum average a little lower in 40 than in 20.
which 5ghz band channels have the best yield in that regard?
It is generally what i use the most, given there are literally zero sources of interference around me on it. (except for a civilian airport, but it never seems to be a bother)

I do not believe this is the reason why its low though.
Its already been proven the radio on the Buffalo high-power routers is designed to output 30dBm, because you can alter it. The power described on the admin pages is the maximum radio power not necessarily the current output power.
For example on my router I can issue "80211n_wlanconfig ath0 set_txpowercap MAC_ADDRESS_OF_WIFI 30" to force the radio to be able to work at maximum power. But it gets resets after so long back to the default, so you have to use cron to keep that setting active. _________________ 2xWZR-HP-G300NH(B) (B0 B0) DD-WRT v24-sp2 (06/14/11) std 17201
