Re: [tlug] Problems with au ADSL/network setup

Thanks for the input, Darren and Jens. From what I can gather from my
notes, the Buffalo router allocates IPs within the 192.168.11.* range
(subnet: 255.255.255.0). The modem allocates addresses within
192.168.0.* (subnet mask: 255.255.255.0). I remember clearly that when
I turned on only the router and connected via wifi, I would get an IP
from within the 192.168.11.* range and access to the router's admin
interface worked as expected. After that however, when I hooked up the
router to the modem (connecting the router's WAN port to the modem's
LAN port), wifi would at first disconnect and then reconnect after a
few seconds, at which point I got an IP from the modem's network range
192.168.0.* and couldn't connect to the router's admin interface
anymore.

Just as Jens said, I originally expected the router to handle wifi and
IP address allocation via DHCP and only use the modem to connect, so I
don't understand how something like this can even happen. The same
problem occurs with both the older IOData router and the newer Buffalo
router, even when no other (local or wireless) clients are present. The
modem simply "overwrites" the router's address allocation. My friend
also reports that he is increasingly often unable to connect via wifi.
The network is present, but when he tries to connect, things hang up at
the point where his computer is to receive an IP address. So there is
definitely a conflict here, but I can't make heads or tails of it.

Generally speaking, do Japanese providers restrict (legally or
technically) the use of wifi-capable routers behind ADSL/Hikari modems?
I'm asking because I remember a recent debate in Germany where
providers forced customers to use their own modems and routers, and
people feared these sorts of restrictions would be the result (e.g.
having providers dictate which hardware you can use on the network and
make you pay extra for stuff like wifi).
