Then I paid three times more for a DLink, and it is rock stable. Hmmm, interesting. I always thought Linksys (at least before Cisco bought them) and Netgear were *much* better than D-Link in terms of reliability. Of course, this was 3+ years ago during my days as an employee at a big-box electronics retailer (we carried all three brands, and guess which brand had a significantly higher return rate than the other two?), and besides, vendor/brand reliability does change over time... Generally speaking, I'm surprised (yet pleased) that Netgear has chosen to open-source their router--it seems that in the past few years, electronics vendors have avoided releasing their wireless hardware with open-source firmware and specs, hiding behind the fear of FCC violations by hackers running the devices out-of-specification (thus violating the license). It'll be interesting to see what Netgear did (and how) to mitigate such possibilities.

The real question is why companies ship routers with so little flash - I can get a 16GB USB flash drive for $AU60, which is less than 4c/MB, so it's not like it'll break the bank. The same goes for RAM - modern Marvell SoCs use DDR, which is also at rock bottom prices.

Brickable?
What I'd like to see is a completely unbrickable router platform for Tomato/*WRT with descent
performance. It is way too easy to brick routers when reflashing them. Reboot too fast after
the flash - *poof*. Choose the wrong image - *poof*. Choose a version that happens to be
incompatible with your particular revision of the hardware - *poof*. Select a bad combination
of settings in the web interface - *poof*.
Most of the times it's possible to "unbrick" by doing a series of "reset nvram" button
presses, but too often even that isn't possible and you'll have to get special hardware and
solder stuff on the motherboard to re-flash.
What is needed is a router with a REAL "reset to factory defaults" button, that restores ALL
flashable components and CMOS to a re-flashable state, nothing excluded.
Brickable?
> What I'd like to see is a completely unbrickable router platform
As long as you have jtag access to the board's chipset/flash then it shouldn't be a big deal
at all. It's what I got to do at work when a programmer fubars a box.
http://en.wikipedia.org/wiki/JTAG
If you want to play around with Linux or programming other types of embedded devices it's a
life saver. The only downside is that some manufacturers only provide proprietary hardware and
drivers for windows.
This is what the DBoard is for OpenMoko
http://wiki.openmoko.org/wiki/Neo1973_Debug_Board_v3
So if you want something that is friendly for hackers look for easy access to jtag port,
adapters, and documentation. (or equivalent) You may have to look up the actual parts on the
board and go to the chipset's manufacturer's website and such to get everything you need, but
this isn't a big deal. As long as you know which pins on the board are the jtag stuff.
Or maybe you may end up with a situation like many BIOS boards were you have a removable chip
that you'd need a special programmer for. Which is fine, as long as it's all documented and
the hardware for doing that is affordable.

That means that you need about twice as much flash as you would otherwise have, which is
unrealistic on cost grounds in most markets (though I do know of some more "professional"
devices that work that way).
What is possible, however, is to have a small bootloader that isn't easily overwritten. The
NSLU2 has a version of RedBoot for this. When started up with a button held down in a
particular way [so you need the $ for at least one button!] this bootloader listens on the
network for instructions to write to the flash. Even if you write garbage, you can still
repeat the process.
Brickable?
Whether or not you need twice as much flash depends on how capable the factory image is. If
the factory image is just a bootloader, and pretty dang generic, you can do it with a small
amount of ROM. In fact, the AT91SAM7 series does that whole thing on chip (it's got a USB
bootloader in the chip's ROM, and if you assert the "erase" pin, it clears the flash and runs
that bootloader). If the USB and that pin are accessible, you pretty much can't brick it
except by damaging the chips.
It doesn't really work if you want a locked-down device, since the bootloader won't enforce
signed-image requirements, and it wouldn't work for users who want their hardware to route
packets out of the box, but it'd be fine for this sort of device.
Brickable?
9/10 you can reflash these things from the serial port - these things tend to have boot
loaders capable of receiving new flash via TFTP (there's also JTAG, but that's a bit too
extreme for most of us).
What's needed is for the vendors to provide an interface to the serial port, e.g. by including
a cheap TTL-serial <-> USB convertor...
Netgear's open wireless-G router for open source hackers
The Linksys/Cisco WRT54GL has twice as much flash memory (8MB) for the same price. The other
specs are essentially identical: 16MB RAM, 4+1 ports 10/100 ethernet with wireless, Broadcom
(MIPS) 200MHz CPU. The physical form factor is different. The lack of USB2.0 ports is a
glaring omission for both boxes.
Hmm, you sure? My WRT54GL has 4MB, and the OpenWRT wiki agrees:

Netgear's open wireless-G router for open source hackers
Where do you get the idea that the WRT54GL has 8 MB of flash? Wikipedia thinks it has 4 MB. It
looks like the new thing is a slightly faster processor replacement for the WRT54GL with a new
number to reflect the different focus.
Junk
I owned the non-open-source version of this router. It was a piece of junk. It constantly
dropped connections. This was my first router, so I thought this was typical--I thought it was
interference from other routers, from the microwave...I moved the router around, which didn't
help. Then I paid three times more for a DLink, and it is rock stable. Looks like the average
Amazon.com reviewer doesn't have better luck with this router either.
I doubt open source firmware will improve this piece of crap. Go try the Linksys WRT54GL
instead.
Junk
That's probably a problem OpenWRT can solve. Hardware doesn't drop connections, software does.
Junk
works for me
i too have the closed-source version and it works fine, though i only use it as an access
point and only with one or two wireless clients at a time.
when used daily, it would need to be power-cycled about once a month (the activity lights
would blink acknowledging receipt of traffic, but the router wouldn't route the traffic
to/from the wireless side). now it gets used less frequently (two or three times a month) and
only needs to be power-cycled every month or two (~1.5 months). i've benchmarked
single-wireless-client throughput overnight and had no problems with the router surviving
that, so maybe it depends on your specific use-case.
i even have a shell script for cacti to scrape the router's statistics/counters from the web
interface, so the closed-source router does everything i want, even in lieu of "advanced
features" like snmp (though admittedly, i have limited requirements).
i bought a buffalo WHR-G54S two years ago, but it's still in the box as the desktop linux
router/firewall it was meant to eventually replace still works great (if it ain't broke, then
don't fix it).
Netgear's open wireless-G router for open source hackers
My ASUS WL-500G Premium has 16MB of flash, 32 MB RAM, 2xUSB2 ports, 264 MHz CPU. Both the
Linksys WRT54GL and the Netgear fall behind. Runs rock solid with OpenWrt. It's the best home
router money can get.
16MB of flash? The OpenWRT Hardware page only lists 8MB. I bought a Linksys WRT350N last year which has 8MB flash, 32MB of RAM, 500MHz ARM9, 802.11n and a single USB port. Unforunately I ended up with a v2 which is only now having OpenWRT ported to it, the v1 had DD-WRT support at the time.

Netgear's open wireless-G router for open source hackers
The flash memory on these devices generally hangs off a word-addressable local bus from the
CPU,
so it is relatively expensive NOR flash. The flash memory in your cheap USB drive is NAND
flash,
which is only block addressable, like a hard drive. Most CPUs require NOR flash to boot from
because it looks like regular memory. It would likely be more expensive to include both NOR
and
NAND flash rather than just putting a little NOR flash down and calling it a day.
Netgear's open wireless-G router for open source hackers
You're generally right about NOR flash being needed to boot, but some vendors support copying
NAND flash into RAM so it can be booted without needing NOR flash - see
http://www.internetnews.com/infra/article.php/2224021 for Samsung and Symbian collaborating to
deliver this. You do need a smarter flash controller though.
Netgear's open wireless-G router for open source hackers
You're right, my mistake. It's 8 MB flash, not 16.
Anyway, I hooked up an old 256 MB USB thumbdrive to it, and with a little hack I use it as the
root fs for Openwrt, giving me more than enough space for additional apps :)
Comparison?
Ok, netgear is playing nicely now. So why do I buy their hardware vs the Linksys WRT54GL?
The Linksys has a very long history built up by now and the specs and price of both are pretty
much equal.
Somebody wants me to jump to their camp there are some things they could do. Populate the
serial port and JTAG with actual headers for a start. Add the max3232 and a DB9 on the back
and I'm a really happy dude. More flash/ram are of course big product features that open up
so many additional uses for a small router/computer. Add an expansion header and make i2c,
SPI, etc access available. Not asking for major additions of hardware, just making otherwise
unused features in the SoC easy to get at.
In general, taking an aging platform and making the source tree available for it is a good
start. Going the extra mile to make it friendly to hacking would be great.
Netgear's open wireless-G router for open source hackers
So how is this news ? Sounds like a blueprint-copy of the WRT54GL that's been available for
several YEARS. The hardware doesn't sound much upgraded either.
How about a bit more RAM, and a bog-standard USB-port or two ? That way it's trivial to insert
a usb-stick if you want space for more software.
