Wireless router with remote access to swtich on PC at home

I recently (September2005-ish) read in a Computer mag that there is a
ADSL wireless router on the market which will allow you not only to
network at home, but also allows you to access your PC from anywhere,
and switch it on if it is not already on. Did anyone read this. Or is
thisfeature actually pretty common. I would prefer not to leeve the PC
on all the time for security and global warming reasons.

How do you expect it will do this? To switch a turned of PC on you
eithewr need a router with an arm, finger, an eye and some form of
hand eye co-ordination or some modification of the wiring in your PC.

I think you may want to re-read the article.

I think you need to expand your knowledge of computers! There is a similr
system in the office I work in already. It was installed in June.

I didn't say it was impossible, it's just not something that gets
plugged in and works. I know for a fact that some of the PC's here
will definitely not be switched on by a router after I have turned
them off.

I recommend Google. Great tool.

looks like your suggestion is valid, but some other scribes disagree.
I think what you are telling me is that the ability to switch the PC on
remotely depends on the right software and hardware configuration, but
isn't necessrily depedant on the router?

It's called Wake on LAN.

Googling for
wireless-router supports-wake-on-lan
produces a number of relevant hits including this one:

My Pro/100 Network adapter properties have :-
'wake on link' options , disabled , forced and OS controlled and
'wake on settings' options, disabled, OS controlled, wake on direct
packet, wake on magic & directed and wake on magic packet
(haven't a clue what the magic part is!)

I would assume yours would have similar options, but the adsl modem and
router would have to be left on. and connected 24/, at least they don't use
much power. also check you power options for Wake on Lan or modem.

certainly I have used the power-up PC settings for receiving faxes back in
the good old days!

I am not aware of a router that explicitly offers that functionality. In any
case, Wake On LAN (WOL) on the PC is a prerequisite. I'm not sure whether
WOL is available with any wireless network adaptors.

Assuming it is possible to wake a PC from another machine on the LAN (ie WOL
is available and operational), then it should in theory be possible to wake
that machine through a NAT router, without requiring another PC awake on the
LAN, provided you can do at least one of the following:

1. Forward a UDP port to the directed broadcast address for the LAN, eg
192.168.1.255. I don't know whether any routers allow this.
2. Forward a UDP port to the limited broadcast address, 255.255.255.255.
Again, I don't know whether any routers allow this.
3. Forward a UDP port to the PC's IP address and add a static ARP entry on
the router with the PC's IP and MAC addresses. This is likely to be
possible on most of the more full-featured (ie expensive) routers.
4. Forward a UDP port to an unused LAN IP address and add a static ARP
entry on the router with that IP address and the broadcast MAC address
ff:ff:ff:ff:ff. May be possible if 3 is.

(The third possibility requires the PC to have a fixed IP address, but you
are likely to want that anyway.)

You would additionally need a utility to generate the required "magic
packet" - which in this case must be a UDP packet directed at the router's
WAN address on the forwarded port.

fantastic. this of great help[
many thanks
