Yes it is a half bad unit. If you make changes to routing or firewall rules, 
you need to unplug everything, power cycle it, say a prayer and hope it 
works. I never got it working correctly at a previous location. Over here it 
works, but have no need for it anymore, since a FreeBSD wireless router is 
doing it's job.
There are many advantages of using a full-blown computer for (wireless) 
routing/nat/firewall, most notably the diagnostics that are available.

Our FreeBSD nat is using:

PPP/ADSL to provider:
fxp0 at pci0:2:8:0:        class=0x020000 card=0x30138086 chip=0x24498086 
rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82559ER 82559ER Integrated 10Base-T/100Base-TX Ethernet 
    class      = network
    subclass   = ethernet

ath0 at pci0:2:10:0:       class=0x020000 card=0x7057144f chip=0x0013168c 
rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR5212, AR5213 802.11a/b/g Wireless Adapter'
    class      = network
    subclass   = ethernet

Wire, soon to be upgraded to Gbit:
xl0 at pci0:2:11:0:        class=0x020000 card=0x100010b7 chip=0x920010b7 
rev=0x78 hdr=0x00
    vendor     = '3COM Corp, Networking Division'
    device     = '3C905 CX-TX-M Fast EtherLink for PC Management NIC'
    class      = network
    subclass   = ethernet

ISC dhcpd, pf including altq provide the services. Currently connected with an 
Intel wpi(4), mother in law a few houses down uses some linksys card on 
windows, daughter uses a D-Link wireless with atheros chip on Kubuntu. 
Currently using WEP, but that'll change when lagg(4) will support WPA on 
wireless interfaces or when I get tired of waiting and decide to netgraph it 
myself somehow.

Problem with today's modular software: they start with the modules
    and never get to the software part.
