So I lost net access the other day. Not sure whether a) my boss didn't pay my bill last month, b) my modem has a problem, or c) there's some other technical problem that I don't know about.

I'm in the process of trying to get it back, but in the meantime I've been able to connect to a local wireless network.

It works fine for web browsing, and speedtest.net gives me better speed than I was getting with Kangnam Cable Company in '06.

Last night I tried to download something using bittorrent, utorrent gave me a firewall message that I've never seen, and within a minute I had been disconnected from the network.

Is the wireless network automatically barring me because I'm using all of their bandwidth?

If so, that's cool, I don't want to inconvenience my neighbours or anything. I'll just refrain until I get the problem sorted out, which I may not even bother with, because I'm moving house in a couple of weeks anyway.

If not, and there's plenty of bandwidth to go around, how do I get around this?

I have encryption enabled, but not forced. Haven't experimented since the first barring, which resulted in me being unable to connect to the network for an hour or so.

Chances are if they're too stupid to put a password they are too stupid to ban your mac address from their network. Should work, try it again if you haven't already.

I'm 'borrowing' wireless as well Very Happy

My belkin wifi router has a built-in firewall. Many of them do. They block the ports you'd need for your torrents. Unless they open the firewall and allow them, you're SOL.

You're already doing something very illegal, but if you really wanted to be nasty, you'd try to find out what router code to type in to get into the router setup and open the ports. It's probably in Korean anyway. Different routers have different codes, but they're similiar:

Linksys: 192.168.1.1.
Belkin: 192.168.2.1
Anygate, Zio: 192.168.10.1

Others are probably somewhere in between. Just type that number in instead of a web address, and you're there. If the person is leaving security off, they probably didn't bother to change the default password to get into the settings page, which is often either blank or the word "admin."

Then there are those people who leave their signal open so they can monitor traffic and steal passwords. There is one router like that near the KTX stop at Daegu (at least there was last year).

access the admin panel by typing in the IP of the access point and try using
username: admin
password: admin

Not difficult to navigate even if it is in Korea

Thanks for the suggestions.

I did try it again yesterday and it's working fine, albeit slowly. I could finally wathc the new episide of Prison Break.

If I was to open the ports on their router, would that be detectable back to me?

As it is, by accessing the wireless the way I am, am I at risk of having my passwords stolen?

How exactly does one get his passwords stolen via using someone else's network? Shouldn't my stuff be encrypted?

depends on what type of encryption you are using. WEP encryption is very easy to break and WPA can be but not as easily be broken. the method to capture the data is by packet sniffing.

It should be noted that packet sniffing takes either a really long time or a really lot of traffic.

actually with the right sniffing software with protocol analysis, it can be done fairly fast. especially on an open network with no security.

to know more about sniffing here is a good resource.

interesting fact about packets from that site:

Many services on the internet send data in the plain text. By default POP mail, SMTP (for sending mail) send data in clear text. The same applies for FTP, Telnet and News clients. ICQ, MSN and AOL Instant messengers send passwords again in clear text. In fact most services send passwords this way.


easier than most people realize...
