Default Stupid question ...

Ok newbie alert ...
I've got an Adsl Router with NO on/off switch.
I want to add a switch close up near router .
The router uses a power adaptor that plugs into wall with a power jack
that plugs into router.

So
1: Can I use either wire (after adaptor) to put a switch into or do I
have to find "live" or "neutral".
2: Will any switch do ie: table lamp style or is that too "heavy" for
the job.

Any help/suggestion appreciated

1) depends on how the adapter is wired. Probably OK either wire. Switch
the wire to the center of the adaptor plug. However, your wall wart will
still be energised and wasting energy. If you must switch then why not use
a power bar and plug the wall wart and your computer, etc into it so all can
be switched at once. If you simply want to block the network connection,
your firewall should have this option.
2)depends on the voltage/current rating of the adaptor. A tablelamp switch
may work but a switch designed for DC will be better. Get a small automotive
switch.

Hi,thanks for the reply Don,

No, what I want to be able to do is simply reset the router without the
need
to pull the connector out of the back as its a in a bit of an awkward place
to reach
around to.
It a D-Link DSL-504T router and it seems to "needs" to be reset every
couple of days
so hence the project ... DC switch it is then (o:

Thanks again ... Ian

Before getting the ole' soldering iron warmed up, check out firmware
releases to see if they fix the problem:

ftp://ftp.dlink.co.uk/dsl_routers_modems/

A quick check on google and it seems you aren't alone. My Linksys
needed a firmware updgrade to prevent it's NAT tables filling up and
over a few days strangling the router because inactive connections (or
external attempts) were being tracked for 5 days instead of being
dumped after a few minutes. Since moving to an unofficial version that
let me specify the time-out it's been running for 4 months without
needing a reboot.

Peer to peer file sharing or using services such as Skype can create
hundreds of connections in minutes, and if your router doesn't dump
the NAT translations when they are old, it'll die trying to remember
them all. Even without these loads, my Linksys's performance would
drop to unacceptable levels after 2 or 3 days.

Routers should be able to work 24/7 for many months without problems.

Thanks for the suggestions. I've already got the latest UK firmware
and have tried different methods to stop bottle-necking happening
within the router settings .. still the same problem though. Yes I do use
Peer to peer software but had no problem with a much cheaper router
i had for 3 years prior to this one.
So I'm waiting for new firmware that may fix this (I've seen a Russian
FW with a more uptodate version number but am not to keen on
trying that one just in case it mess's the router up.
So its back to the switch idea for now (o:

Many thanks

Ian

if there's no electrical connection between the earth and either output wire
you may switch either wire use either wire,
(if there's no earth pin use either wire it makes no difference)

otherwise you should probably check for an electrical connection between the
output and earth...

2: Will any switch do ie: table lamp style or is that too "heavy" for

Yes, that'd be suitable. there are also dual pole swittches that will switch
both wires, I'm not sure if table lamp switches are like that or not.

A table lamp switch in the U.S. almost always switches only the "hi" side.

Maybe a extension cord preferably with its own switch would be a quick and
dirty answer as well as a safe one.
