Share public wlan connection?

Hello,

Will be off for a week in a hotel soon, where I normally utilise their wlan
for the week. It's not particularly cheap unfortunately, and this time, my
dad wants to take his own laptop too.
Assuming we get a room next to each other (usually the case) and he can
"see" my machine, can I share my connection to the internet? i.e. be
connected to an AP but act as one too? Is it as simple as just setting up
ICS (I'm using Vista Business) or do I need something cleverer?

The internet connnection is one of these that transparently redirects you to
a "login page" and then works as long as that stays open, so not sure it
would just work from the second PC or not as it wouldn't have the relevant
cookies etc?

Depends on the wireless card. I doubt it.

Vista sucks arse, so I very much doubt it.

a) Get a different hotel ? One which doesn't rip off customers for network
access ?

b) Sniff around for another provider in the area (internet cafe, coffee bar,
etc..)

c) Some hotels have fixed wire access as well as WiFi, so connect the
primary laptop to the fixed wires, and then try using the wireless for ICS.

d) Use Bluetooth for the laptop to laptop ICS (if lacking bluetooth on the
PCs, it might be possible to USB to a mobile phone then bluetooth from phone
to phone, thus connecting the PC's; I've not tried such a trick in ages, but
can't see a fundamental reason why it wouldn't work).

e) Hotel access is often a case of a generic login/password which they
change regularly, so once one person has it you can give it to someone else.


I think you're stuffed on WiFi ICS if also using the same WiFi card for
connecting to the hotel system. If you have two WiFi cards in the Vista
Laptop, then you may be able to ICS onto the second WiFi card if set up to
"ad hoc" mode.


If you get ICS between the PCs, but run into a real block with the login
credentials, then remote desktop access might be a way out. Admittedly you
loose access to the keyboard/screen of the primary machine whilst it is
being remote controlled.

I do actually have a spare USB wireless dinkle - so I can at least test
accessing, say, my home network via ICS I guess.

Yes - that's the bit I'm wondering about. I'm hoping that once the primary
machine is "logged in", then the channel is effectively open for any
traffic... but that remains to be seen. Can't really test that bit in
advance as I guess it varies from one system to another.

Ah- yes, unfortunately my dad likes it - it's rather a nice hotel... and
luckily he pays too, so I'm not gonna complain

None nearby (at least not last time I was there)

don't think so...

I also have a spare USB wireless thingy, see other post

The AP's are open - it's actually run via Swisscom (presumably a franchise
thingy, as my login details I get while I am there usually work in the BA
lounge in the airport on the way home too)

You've not used Vista have you? It allows you to set it up as a wifi
access point.

Non at all judging by his comment.

Let me think...because you'd not be able to connect?

Try engaging your brain and think about it. If they used WPA and handed
it to you when you paid for it, what's to prevent you from giving the
key out to all and sundry or just using it next time you're there? Sure
you could use WPA with a Radius Server but then you've got the problem
of generating passwords. Far better just to have a script on a webpage
that runs an algorythm against the password you've been given and gives
a pass or fail based on the result.

Well for starters, WPA is crackable using freely available tools.
Secondly (although this is becoming less of an issue), there are still
plenty of wireless clients that don't support WPA about and WEP is so
insecure as to be pretty much useless.

Also if they did use WPA then it would restrict them to using one
passcode for all clients. Even if they are doing this with their proxy,
I'll bet it was designed to be able to issue individual passwords with
time limits.
