Speedstream 5360 modem died, headache getting a bit better!

Hello again,
Referring back to this thread...
http://groups.google.com/group/comp.dcom.xdsl/browse_thread/thread/c098b5496ea8d69e/736f255a547a2b71#736f255a547a2b71
Thanks to Gary and msg once again, for their suggestions. I've
restored all of my home network, with my Linksys router+WAP behind my
new Actiontec DSL modem+router.
I found an 18 VAC power supply in my box of old electronics, but
unfortunately it was dead. I also tested the power supply from the
old Speedstream modem with my voltmeter -- and got 21.6 V? Is that
out of spec? I thought that my voltmeter was true RMS -- it measured
115V from the AC outlet.
The key to getting things working: I disabled the routing features on
the Actiontec and ran it in transparent bridging mode. No one ever
came out and told me that transparent bridging mode was the best way
to emulate my old modem, and I read dozens of web links trying to
determine whether this was true. But I eventually became comfortable
with the routine of switching cables back and forth, and performing
the factory reset on the Actiontec. I decided I could experiment at
will, and eventually I got all the settings correct.
I was mistaken when I said that the modem offered two transparent
bridge modes. There are two modes for managing IP addresses, when two
conditions are true: 1) you are operating the modem as a transparent
bridge, and 2) you have a static IP on the WAN side. That didn't
apply to me.
I think that I'll keep the Actiontec modem, even though I initially
considered it too smart for its own good. Unlike any used modem I
might buy, it does have a warranty. The router inside the Actiontec
box will also serve as a backup hardware firewall, in the event that
the Linksys ever fails. Furthermore, I'm running mostly Linux on my
terminals, and I don't know how to configure PPPoE on Linux yet.
Again, in the event that the Linksys fails, having the ability to put
the authentication information in the modem makes some sense.
Now, even though everything is functional, there are three more issues
I would like to address.
First, there is the mystery of why the modem is working at all right
now, even though the Internet LED remains off. When I connected the
modem directly to a single computer, the Internet LED was green.
Second, I noticed a significant reduction in browsing speed once I got
the router back in place. Now, I'm still getting my full DSL
bandwidth (1.5 Mbps download and 384 Kbps upload), once a lot of
packets are streaming to/from a single source. However, from watching
my web browser run, I can see that DNS lookups take considerably
longer when I connect through the Linksys than when I connect straight
to the Actiontec. A web page with lots of links loads very slowly.
Where I should look for a performance bottleneck?
Finally, I would like to access the modem from my local net, if that
is possible. Swapping cables, rebooting, and reprogramming gets
tedious. But the modem is on the WAN side of my router. The modem
has a default local IP address of 192.168.0.1 and is accessed through
an HTTP interface. With the Linksys router in between my terminal and
the modem, the web browser just hangs trying to access that IP
address. Any suggestions?
Thanks once again for reading!
