How can I connect with WiFi to a computer with ethernet only?

In my house I have an ADSL modem with WiFi. I can connect my laptop to that ok,
with no problems.

I have a small rackmount server that I'd like to stick in my garage, as it is
noisy. The problem is I don't know what I need on the server to connect it to my
ADSL modem. The only usable connection on this machine will be via ethernet.
Forget about USB, as no wireless cards will have drivers for Sun's Solaris. In
any case, I'm not even sure if it has USB on it. (not near me to check).

Security is not an issue - any communication between me and the server will be
via encrypted SSH. Using a power line device is out of the question, as my house
has a 3-phase supply, and the garage is on a different phase to the house.

I do not believe a wireless access point will solve this, but am I mistaken? I
have one of those sitting around, which I used when my old modem did not have
WiFi. But now it is redundant.

Is it an Ethernet bridge, or similar I need?

I should have said, there is a second machine I want to put in the garage too.
That is a Unix workstation running HP-UX as the operating system. Can I link
these two machine via a switch, then connect that switch to a wiress device so I
can connect to the ADSL modem?

Looking on the web, it seems a Wireless Ethernet Bridge may be what I need. Do I
need two of these, or will the fact my ADSL modem has WiFi mean I only need one?

You answered your own question.

Just the one, with a switch to connect multiple hosts.

 

Why not do the job correctly and use wired Ethernet with GB switches?
That way, you can install GB Ethernet for your LAN that will be immune
from most interference that may be present in your garage or from
neighbour's wireless systems. A similar set-up works well here. (Server,
2-3 computers, wired router for the WAN and an old router as wireless
access point when needed)

I've found Wireless to be less than acceptable when going through some
types of exterior (and some interior) wall construction. Furnace ash
breeze blocks or aluminium foil are excellent for blocking transmission
of 2.5 or 5Gbps wireless signals...

 

Be aware that many wireless access points can be configured to act as a
bridge, and most incorporate a switch. Worth checking the documentation
for the one you have already.

A quick Google suggests there may be solaris drivers available for some
cards. It's decades since I worked on Solaris so I'm not in a good
position to judge how useful these might be though!

A cable is always faster and more reliable...

I do actually have Ethernet going into the garage, but not in the part I need
it. I've a pretty large garage, consisting of places for two cars, then there
are two rooms at the end. The freezer sits in one, the washing machine and sink
in another. Part of the reason for mounting one of the computers in the garage
is to raise the temperature a bit, so pipes do not freeze. I really would be
difficult to get a cable into the room where the pipes are.

Not only that, but I think my wife would object to me running more cables down
the walls.

I will try my laptop in the exact location first. I must admit, I'd not given
that problem too much thought. I know the laptop works fine the same distance as
the garage, but I've not really tried it inside.

Ultimately, the main use of this will be for others to access the machines via
my ADSL link. As such, the speed of the ADSL is likely to be the limiting
factor, and not the WiFi.

Being in a rural area, interference is not likely to be much of an issue. There
is only one or at the very most two other WiFi networks within range.

Wouldn't this http://tinyurl.com/yj5e4cy be a lot simpler?

I have a wall mounted heater fan heater and so called 'economy 7' storated
heaters in the garage (I use oil for the main heating).

But the point is heating like this is just wasted enerfy. If the computer needs
to be on anyway, I might as well locate it in a place where it's heat output is
useful.

The two computer take around 430 W when idle, and probably 500 W + when doing
CPU intensive things, which they often will do. Hence it makes sense to use the
heat output.

If all I wanted was a heater, I just just switch a computer on and not bother
networking it at all.

I do not call the frugal application heat that is minimally sufficient to
save my plumbing as "wasted".

It would be more economical to put it in a place that will far more often
benefit from the released heat - a place you need to keep warmer such as
inside a home or a greenhouse, etc. Any day you need to run your central
heating the computer will provide some modest base level of heat that you
would need to provide from some paid-for energy source anyway.

That would be more wasteful and also perhaps unsafe because a computer does
not have the frost-stat that can put it on for just the minimum number if
minutes needed in the small wee hours of a chilly February morning.

I've no greenhouse, but the problem in the home is that they make rooms
unbearablly hot. I run 3 computers in the house

* Sun Blade 2000, around 450 W. (Soon to be replaced by a Sun Ultra 27.)

* HP C3600 around 350 W

* Sun Ultra 60 (200 W), but soon to be replaced by a very noisy Sun netra T1
using only 60 W.

So that's 1,000 W running 24/7, which unless in a very large room, just makes it
unbearably hot

My wife would object if I started locating computers in other rooms in the house.

The only downside to heating the garage is it will make it even more attractive
to mice and other wildlife which use it in the winter.

Yes agreed, but balancing all issues, I think moving one or two computers to the
garage is sensible. It will reduce noise (a constant irritation for my wife) and
heat output.

Yes, a bridge can receive your wifi and "output" via ethernet.
