B1 and B2 are vendor hardware revisions. Trunk refers to the SVN tree, and r18621 to the version of the SVN tree from which version on it supports a given feature. Kamikaze is not trunk; Kamikaze is a branch, just like Backfire, and specific versions of those branches will be (or has been) tagged as release version.

You can get OpenWrt/Gargoyle version for DIR-825 here

OpenWrt Backfire 10.03.1-RC3 - DIR-825 b1

Both links above are to version of firmware "squashfs-factory"
You install those from factory settings (web UI with stock firmware)

RE: WISP client
Yes, it works in such mode.
I also got WDS running on it.

This just shows that some router was announced before another (longer time on the market).

And/or - one router has problems, another is working much better (more stable, etc.)

I have now TP-Link WR1043ND, it's a very nice device. Can recommend it to other people.

Have you happened to know whether this device supports 3G USB modems? (version B of DIR-825 does, as far as I know).

I guess it really depends on OpenWrt (particular version) and not on hardware.
If USB port works, support for 3G USB modems would work in the same way on different routers.

BTW: D-Link DIR-825 is quite expensive device
I would recommend instead of it either TP-Link WR0143ND or Linksys WRT160NL.

P.S., Take a look at this discussion thread
Hope you will find it useful and interesting

for what its worth I think the 3700 is a good router, some quality issues in the beginning but latest ones are going great.  I have been spending allot of time with the dd-wrt development on it which seems to work pretty well right now (though mine is having a kernel panic issue with samba and transmission but I am the only one to have this problem).  as far as dd-wrt goes its only faults are that wireless speed has gone down a bit since moving to the 2.6 kernel, though the ath9k driver is supposed to be integrated soon which (hopefully) should fix those problems.

I LOVE the distance i get out of the router, its at some points ridiculous.  I tested it by walking outside and down the block over a bit and sat on a swing, and still has connectivity.  a friend a block away through one of their walls was on my wireless for internet.  This does heavily depend on the client's abilities also though. 

Openwrt gives me hope of getting rid of this kernel panic which kills just the two wireless connections.  but i must say again that this problem has not been reported by anyone else anywhere in dd-wrt or anywhere... frustrating.

Those are very good, valid points.

My guess eyeryone should answer following question, before making selection:
What is the primary usage for this router?
1) Router - just router, also known as Internet Gateway (IGD, Internet Gateway Device)
It has NAT functionality and Firewall. Usually runs DHCP server as well.
In typical scenario it connects to provider using PPPoE, PPTP or L2TP.  Or using WISP (Wireless ISP)

--> for such scenario Netgear WNR3500L is a good choice. It has 8MB Flash/64MB RAM
You can avoid problems with Broadcom (if any) by disabling wireless

2) Wireless Access Point (WAP)
Connects different wireless clients in your apartment/building to this WAP.
Another device (Router/IGD) handles connection to Internet and NAT.
NAT/Firewall are not needed. DHCP is optional.

My choice here is Atheros chipset - as it would work well for item 3) too.
Just make sure that you are not paying extra for functionality you don't need (NAT, Firewall, Extra Ethernet LAN port)
TP-Link WA801ND or WA901ND offer good value.
And they would work with stock firmware (which is using Linux kernel 2.6.15)

3) Wireless Range Extender/Bridge/WDS Station
Required functionality is similar to item 2) - WAP.

My choice here is Atheros chipset.  And it would work well for item 2) too.

See my recommendation for item 2).

4) NAS device /shared USB printer
Router needs at least one USB port for this.
Wireless or ANT/Firewall are not required.

WNDR3700 is a good choice here.
Netgear WNR3500L would work fine as well, buthas much lower price tag (about $100).

But if you need high-performance NAS functionality, you may consider buying dedicated NAS device.
Dedicated "Print Server" box is also good choice for USB printer sharing over LAN.

5) Extend wireless coverage in your area, without buying one or more AP/Routers
You need external detachable antennas for this.  2x2 MIMO or 3x3 MIMO is a plus.
If your router doesn't detachable antennas, you can't do it. So WNDR3700 is not an option here.

Distance you can get from router to connect at reasonable speed depends on:
- chipset
- wireless transmission power (indoor 14/outdoor 26 - typical values) of Router/AP
- antennas (1, 2, or 3; antenna's gain)
I switched standard antenna on my ASUS WL-500G Premium for 6dBi high-gain Yagi, and result was wonderful!
Old notebook with Ralink RT2500 chipset and weak antenna was able to connect to AP from kitchen.
- MIMO - yes/no; 2x2, 3x3, etc.
- chipset, antenna for wireless client(station)
Atheros with external antenna would work great.

So all this depends on your budget and time you are ready to spend on deployment.
If notebook supports just Intel Centrino (any flavor) and you are not ready to buy ExpressCard or USB stick with Atheros chipset and External Antenna, and you have coverage problem - you need to change your router to a better one, or buy WAP/router capable to work in WDS mode or as Repeater, or upgrade antenna to a high-gain directional or omnidirectional.
So, not everything depends just on router itself, or its firmware. :-)
