New Buffalo WHR-G125

[seaweedsteve]

Just noticed this is out. The old WHR-G54 has been "out-of-stock" for
a month and this is now showing up - in it's place?

Wonder what the difference is, other than the case. I see that the
antenna is probably no longer "hi-gain" which means what? 2 dbi vs 4.
Is it fixed or removable?

Also looks like the LAN lights have been moved to the front.

Firmware? RAM, etc? Might they be pulling a Linksys?

Anyway, it's good that they have a super-cheap solution again, because
sometimes that's all that's needed.

Inicidentally, the WHR-G54 is still up as a product at Buffalo (on
some pages). Just can't buy it anywhere right now.

According to Buffalo the WHR-G54 is now obsolete. I have a couple of the
WHR-G125s here that were shipped in place of the WHR-G54s but haven't
had a chance to look at them. I will post an update.

The WHR-HP-G125 has an FCC ID FDI-09101584-0 if you wish to look it up.

Here is what I have found:

whr-g125 & whr-hp-g125 are the same internally.
They have different antennas.
Both have the same FCCID FDI-09101584-0

They are powered via a 3.3V inline wall-wort,
in the same style as the whr-hp-54g.

whr-g125 has a non-removable 2dBi ant. attached via coax to the pcb.

whr-hp-g125 has a 4 dBi ant. with a rp-sma ant jack
that is attached to the pcb via coax.
The antenna pictured in the FCC pix appears identical
to the antenna shipped with the older whr-hp-g54.

According to http://wiki.openwrt.org/TableOfHardware
the 4MB flash & 16MB ram remain unchanged from the older whr-g54 series.

The new models use a Broadcom BCM5354 chip
where the whr-hp-g54 uses a BCM5352.

from http://www.linleygroup.com/npu/Newsletter/CE/ce061129.html
"BCM5354 Adds 802.11g Radio -
Also in November, Broadcom announced its BCM5354,
an upgrade to its BCM5352 802.11g router-on-a-chip.
The new chip, which is already in full production,
adds a direct-conversion radio to its predecessor.
The resulting product combines
a MIPS CPU,
a five-port Fast Ethernet switch,
and all 802.11g functions except for the relatively low-cost RF front
end."

http://wiki.openwrt.org/TableOfHardware shows it running at 240MHz.
The older whr-hp-g54 runs at 200MHz.

From the FCC site I see there was a change made in the application.
First application date is 03/26/2007.
A "Class II Permissive Change" has a 04/12/2007 date.

The changes:
WAN jack changed from Black to Blue.
A heatsink has been added to the Broadcom BCM5354 chip.
The AC power adapter specs were changed
from a universal 100-240VAC input & 3.3V,2A output
to a 100-120VAC input & 3.3V, 1.2A output.

Great work. Thanks. That fills in most of the gaps.

I wonder about how the gain and sensitivity compare between the new
and the old HP.

fwiw

from: http://www.dd-wrt.com/dd-wrtv2/index.php
"in my first tests based on a sample provided by Buffalo, this router
was showing a significantly better receiving sensitivity than comparable
older broadcom based routers like the Linksys WRT54G."

"DD-WRT does support this Router in since mid of May in our V24 release
series. watch out for this new product at your local stores."

"The DD-WRT Team has made a special build for this router series to
support the new features of this wifi chipset, consider that this
firmware is not compatible with any other Broadcom router."

Interesting how they compare the new Buffalo to the old Linksys as
opposed to the old Buffalo. Then again, the old WHR-g54 had a 4dbi
antenna and the new has a fixed 2dbi.


I'm still curious how the new HP compares to the old HP. I guess
nobody has one yet.

Not shown at Buffalo.

We'll find out soon enough.

Not quite non-removable. I took mine off and placed an external antenna connector. There is an online tut showing you how to do this:
