Re: PS3 Kills Wireless Laptop Connection

Likely. How is the IP address setup on the laptop? If it's being set as
static and that address conflicts with the Wii and/or PS3 then you've found
your problem. You can't have more than one device on the network using the
same IP address. And neither can any of them use the same address as the
router, of course!

Nice. Yet another broken DHCP client or possible DHCP protocol
incompatibility.

Heh, just ran into that with my networkable thermostat. Seems it can't
handle a DHCP lease that has more than one gateway router.

I didn't know anyone had such a thing. Might be useful for my
mountaintop sites. Got a link?

Do you mean more than one *default* gateway? Setting up more than one
gateway to remote offices is fairly common, but that's handled by the
router. Windoze and Linux both handle multiple gateways, but I've
only used that for automagic fall back when the main router goes
comatose. Unless you have more than one route to the internet (in
which case you'll need some kind of routing protocol such as RIP,
OSPF, BGP, etc, I don't see any need for more than one default
gateway. Also, all of the cheap routers I can easily access only
allow one default gateway in the DHCP server config. I'm too lazy to
slog through the RFC's to see if they allow more than one default
gateway via DHCP.

Whatcha doing?

Sure, proliphix.com. I've got this an NT20e.
http://www.proliphix.com/NT-Basic.aspx

This one has not only it's built-in temp sensor but supports two more. I've
got one outside and one in another part of the house. There's even a script
to pull the data into an RRDtool monitoring database. I've not yet
configured that. The unit hosts it's own web page for status and control.
That and it has a programmable API for integration with home automation and
other programs.

It's not inexpensive compared to standalone units. They also have more
commercially-targeted units (but I've not used any).

> Unless you have more than one route to the internet

Yes and I have routing set up for it. I don't really "need" anything to be
smart enough to deal with multiple routes. I've found some devices really
don't like being handed multiple gateways from an Windows DHCP server (the
thermostat being one). But this isn't a problem as those devices each get
their own DHCP lease reservation set up; which is explicitly configured for
just one gateway. Yes, you're right, most SOHO routers do not have this
flexibility and most situations wouldn't require it.

Balancing between some inbound services using a static DSL connection and
the dynamic IP FIOS connection.

Thanks. However at $360/ea, I don't see one in my future.

No SNMP. So do they just scrape data off the web page?

Well, there's another common setup that some DHCP clients find
difficult. I frequently have LAN devices that I do NOT want their
traffic to appear on the internet. Network printers that call home
regularly is the most common example. So, I set the default gateway
to either blank or to the network printers own IP address. No problem
with a static IP setup, but with DHCP, it requires that the client
allows a static gateway IP, but a dynamic DHCP assigned IP and
netmask. Batting average is about 50% on print servers and network
printers. For those that won't, I have to setup a filter rule in the
router or use a static IP address. Not a big problem, but it bugs me.

Load balancing between two radically different speed network
connections is always fun. You could cheat and use a load balancing
router such as:
<http://www.edimax.com/en/produce_list.php?pl1_id=3&pl2_id=>

With Windoze, there's no internal load balancing with multiple default
gateways. It looks at the router metric, picks the cheapest, and
sends everything via that route. If you want to change gateway, you
have to tweak the route metric. I don't think any commodity network
appliance firmware can do even that and is limited to one gateway.

Thanks much.
