: I think somebody is piggy backing my wifi!

My internet has gotten considering slower. I am on an all wifi set up in my condo. It is WEP secured. It takes about 10-15 seconds to load ehmac.ca on all of my macs. Something is up. It started doing this about a week ago and I thought it would just go away.

Is there any programme or way to tell if someone is logged onto my network?

Has your wifi hub have usage lights? If their flashing and your computers aren't on the net or are off you have a problem.

If could also have something to do with network throttling (by Bell or Rogers) but it is very unlikely.

Have you done any speed tests? Could it be you are just hitting some busy sites?

WEP is hardly worth using these days - it can be cracked in minutes with the appropriate tools, which are easy to get. Try setting up WPA2 encryption.

Go into your router logs and see....if you don't have logging enabled, do so and keep an eye on them.

If someone is piggybacking:

Turn off broadcasting
Turn off DHCP
issue static IPs to your machines
Turn on MAC addressing

Last resort, turn off the radio for a week and use ethernet. The thief will move on.

Have you tried resetting your modem? ie: unplug, count to ten then replug.

I'm on Rogers and experienced a similar problem about a week ago. Things speeded up tremendously after a reboot.

Oh, thank goodness.

When I first read the title of the thread, I thought it said that someone was piggy backing your wife!

Would someone be kind enough to explain the negative effects of 'piggybacking' someone else's unsecured WiFi network? In our old neighbourhood, we did this all the time with mutual consent - when needed. None of us were online gamers or downloaded music or DVD's or whatever. So no big deal.

We just moved and I piggybacked a couple of times to a local, unsecured network to check my emails. But I certainly wouldn't do it if it has a negative effect on any of my new neighbours' internet useage!

You never know when your neighbour will hit their cap and suddenly be faced with a large overage fee. Also you want to ensure that your wifi is locked down; you might find the police at your door looking for a 'file' of interest that someone downloaded over your connection.

I heard of a man in Toronto who was implicated in downloading child porn. It ended up that someone had parked outside of his house on a laptop and was downloading such content through his open network. I have WEP, I thought that was enough. Apparently not I guess. WPE2 is better?

At my door - only if it contains donuts. ;)

Thanks, I forgot about the "porn being downloaded at the end of your driveway" scenario. I bought a book a few months ago about the best methods for securing a wireless home network but my son hasn't had the time to do it and I figured I wasn't technically up to doing it correctly. Guess I'd better get to it. Are there any online tutorials to walk me through this and do it right?

Tutorial: How to set up WPA2 on your wireless network (http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9002706)

it's a fairly windows biased article but it gets the main points across.

If you have an Apple Airport router (Express, Extreme, Time Capsule), the Airport Utility in your Utilities Folder will walk you through setting up security.

Just add that it should be a hidden/closed network:
Click on the Wireless tab, click the Wireless Options button, check the Closed Network checkbox.

You can also set up MAC access via the Access tab. You'll need the MAC addresses of computers/wireless cards that will access the network.

With the choice of WPA2, a hidden network, and MAC-only access, you're about as safe as a home network can get.

Thank you! :) Actually, I'm a Windows-biased type of guy - for now. ;) My son uses a Powerbook and I just bought an old iBook G3 to play with (before getting a Powerbook too) after a 'lifetime' of Windows abuse.

The only Apple I own is the Macintosh in the fruitbowl on the kitchen table! ;) (And now, this old iBook g3)

Sounds good to me!

(Haven't had time to do any of this - extended hospital stays really take a bite out of your play time! ;) )

A few months ago I upgraded to all the Xtreme D-link stuff - but my son suggested we get the top-of-line Airport thingee instead (since we'll probably go all Apple before too long). Until that happens, we can use that blazing Airport router for Apples _AND_ the PC's we're currently working, correct?

Perhaps it is an urban myth - but one can get in the middle of such a mess if they trace back the address to the base machine of the network. Not that one would be liable, since such material would be "in transit", but it would be inconvenient to have to explain it to investigators.

WEP is fairly easy to crack, WPA2 is a better protocol. As well, one should make sure to not enable any of the features that they don't actually need. If you don't share a printer, turn it off, or you may end up with a midnight prankster wasting your paper and ink. Same with file sharing or whatever - just shut off anything you don't want.

As well, one can adjust the transmitted signal level to better match the area you want to cover. Most midnight cruising wifi crackers will skip on the "underpowered" signals.

Another thing ignored is that of channels. Most routers default to Channel 6 - so if you are in a condo where people have a lot of routers set up to Channel 6 - you will obviously be fighting a long series of handshaking problems as everyone will be forced to share the same channel. A utility like KisMac or iStumble will identify all of the routers within signal distance, and you can easily determine which channels are free or underused.

Here is a link to the CTV story about this case back in 2003

CTV.ca | Police warn of Wi-Fi theft by porn downloaders (http://www.ctv.ca/servlet/ArticleNews/story/CTVNews/1069439746264_64848946)

From what I remembered the case was in Toronto and this google search found a number of related links:

It probably happens all of the time. One night recently my friend and I went out on a midnight war drive, just to see how many people were running unsecured wifi portals. There were a smattering of those who do leave a slow speed connection open, a larger number with no protection. One dude had an open connection that was as fast as my friend's special high speed connection (he runs a business and has a pretty large pipe for his server) - and "N" speed to boot...

I imagine there is quite an amount of furtive behaviours on the go, considering the number of free connections found in a neighbourhood in the space of an hour and a half. What was more bothersome was the number of people who think they are secure with WEP, and the small number of people who actually set up WPA2. A large number of people do not even set up anything other than the default - so the night of our drive left a lot of people with passwords 'installed' on their routers. beejacon

How could I track if someone is piggybacking my connection when shared from my macbook using internet sharing. (i tried securing it... then the people I wanted to have access to it couldn't get it, no matter what we did)

Have you tried turning "logging" on? If you've got an Airport base station in your configuration it should be do-able.

AirPort Extreme: Remotely logging base station activity (http://docs.info.apple.com/article.html?artnum=107993)

Most other wireless routers can do this too - I just don't know where their documentation is...;)
