Is there a way to see if anyone is connected thru your connection?

Yes, absolutely. Your router has a web interface that is accessible from within your network. For most routers,, type in address 192.168.1.1 in your browser's address bar. You will get a prompt to enter the admin password for the router. Once you enter this, you will be presented with the router's administration "website." You can go to your DHCP table, and see every device that is connected to the network, either wired or wireless.
Note that for a few routers, specifically ATT Uverse equipment, the address is 192.168.1.254

Thanks a lot guys!

Yes and my router default is 192.168.0.1 (eta: my router is a Netgear and my previous D-Link was also 192.168.0.1)

It is probably worth googling your router model and "default IP address" if you are not sure what it is.

On my router, once logged in there is a "connected devices" button which shows me all the devices on the network. I actually have my network locked down so only specified devices can connect anyway - you should also be able to turn that feature on if you want to stop random devices from connecting.

There are a bunch of ways to make your wireless network a whole lot more secure, but seeing as you haven't asked that yet, I won't rattle off a load of potentially irrelevant stuff LOL.

Let us know if you want more info.

Actually that was my main reason for asking. Any further info would be appreciated.
Thanks

Here are some basic guidelines for securing a home network. The essentials are enabling the router's security (requiring a key to log on) and changing the network's default name and password.

First things first we could do with your router model as the config is different for all of them.

In essence, I would look at

1) ensuring you have encryption set, preferably WPA/WPA2 with PSK2 / AES but definitely not WEP as that can be cracked in seconds
2) ensure the default admin password has been changed to something strong
3) if you are never going to want to access your router admin from outside your home, make sure remote management is disabled
4) change your SSID (essentially the wifi network name) from the default
5) disable broadcasting of the SSID (this will mean it won't be visible to devices searching for a wifi network)
6) enable MAC address filtering... This is where you can essentially list specific devices that are allowed to connect to your network. It needs a bit of management every time you want to add a new device to your network but it gives you strong control
7) make sure the firewall of your router is enabled (newer routers tend to be firewall on by default it some older ones are firewall off by default). If you have more than one device on your network that needs accessing from the Internet in some way you may need to configure port forwarding / NAT - I.e. if you are serving your iTunes library from a specifc pc so that you can access it over the internet you need to tell your router that if it sees incoming traffic for iTunes it directs it to the correct pc - but you may have a filesharer running on another machine so you need to direct filesharer traffic to that machine). This is all done via port-forwarding.

There are probably other things that can be done but these are the settings I would look at in the first instance. Most of the terminology I have used is generic to all routers, but the mechanics of changing these settings will differ from one router to the next.

change the name to something like "virus32_install.exe" for fun.

this actually can make your network vulnerable, just leave it broadcast and set a very tough passkey.

I favour "Police Cybercrime Unit" as an SSID :-)

Kind of deters moochers....

Fair point.... A determined hacker can still discover your SSID anyway, and this can just cause problems with config if you can't find your own network and aren't particularly techie so feel free to skip this one :-)

My latest favorite setting is the dual networks. My wife doesnt want the kids to be able to access wireless at night so I set the 2.4ghz network with one passcode that the kids have and set that network to stop broadcasting from 11pm to 6am and leave the 5ghz network broadcasting 24 hrs for myself and her with another passcode.

Indeed. I love this feature of the newer routers. We don't have kids, but we have a steady stream of guests that want to use the wifi. We have a network for guests that has a simple password that human beings can remember, and a separate network with a 50+ character crazy password that nobody could ever remember that our own stuff is connected to.

As far as Lawry's list....

I agree with Mike that turning off SSID broadcasting causes more trouble for legitimate users than security benefit. Same thing with MAC address filtering. MAC addresses are easy to spoof, and if you're doing the other things right (WPA2, good passwords), MAC address filtering is probably of minimal benefit. The rest of the advice is all good stuff.

The SSID on my totally locked down TrendNet router is "Linksys". But I'm just being perverse. The main thing about SSID names is to *not* give it a name that clearly identifies it as yours, especially if you're an interesting target.

One of my coworkers spent an entire Christmas break trying to break into some neighbor's wifi that had the SSID "Get your own wifi, b*tch!" He eventually got in, but it took 11 days on a 128 core blade server to break the password. Once he got in, he changed the SSID to something else that was even more unprintable, changed the password, and went back to using his own wifi.
