WiFi getting hacked?
 
I have had ATT U-verse for awhile now and have on several occasions found the wifi light on when none of my wifi devices are on. Motorola NVG510. I have changed all the the default settings and have hidden the SSID but it has happened again. Only thing I could do was turn of wifi. Is this a fluke or am I actually getting an intrusion. Nothing shows up in the device list that looks foreign. I am thinking the light may be on when no one is actually there.:huh: Any one know?

Even if you have no devices on, your router will still be sending out a wifi signal. It has to be on all the time in order for your devices to connect on demand. If you have phones on wifi, they may be checking email from time to time as well.

As far as i know it is on all the time to allow you to connect a device at any time, like dj said. I have the same modem/router with AT&T U-Verse and the wifi light is always on and I live out in the country surrounded by corn/cotton fields with one neighbor across the street who has their own wifi signal.

Usually you can list the clients connected to a router, why don't you look and see if there are any connected that you don't recognize? You can also see the amount of data being used in one form or another. See if any data was transfered while you know you were idle.

Agreed, typically the "wifi" light on a router means that the radio is turned on. It doesn't necessarily mean that anyone is connected to it.

I think a better approach would be making sure to lock down your router.
I've found the best way is to do 2 things.

1.) Use a strong password for the admin login for the router itself (the default is EASY to find on the internet).

2.) Use MAC address filtering for allowing wireless connections.

MAC filtering and turning off the SSID are a false sense of security. MAC filtering only works, when you are using a Radius Server on your network, to manage who can and cannot connect to the LAN.

As for the Wifi light, if the unit is pinging for any available wifi devices, the light may flash on and off, or just stay on steady, depending on the unit.

Not true. Many routers have built in tables for MAC addresses.

True. It's easy to clone a MAC address.

Only if you have it. But first you have to have physical access to the network. There is a lot that goes into securing a Domain, unlike a home LAN, but again you have to be able to physically connect to the network in the first place.

The OP is talking about a home network and his gateway supports MAC address filtering.

As I have already stated, MAC filtering gives a false sense of security, unless you are using a Radius Server, to control what is going on.

It should not have been brought into the equation, since all the OP was inquiring about was why their wifi light was on.

In my case the light only comes on when one of my two laptops (or both) is on and connected via wifi. When those devices are both off the light is normally off indicating there is no wifi connection. On three occasions I have found this light on when neither of my wifi devices are on. I check the modem/router page and the list of devices but it shows only my gizmos and whether or not they are on or off. If I run a refresh nothing else shows up. I have changed all the defaults to obscure stuff that isn't likely to be guessed and hidden the SSID so I can't understand if this is invasion or quirky behavior or the NVG510.

Do you have a smart phone? When I'm home my 4s is connected to the home network.

Most smart phones have that ability.

PoleCat 11-08-2013 07:29 AM

Wouldn't that show up on the list? Also, wouldn't the smart phone need the particulars of my wifi to connect? They are LG Xpression phones. (they suck)

I and no one else here has any idea what you're talking about. This is a home router. It allows users to connect wirelessly by assigning them an IP via DHCP. The MAC filter says that only users with a specific whitelisted set of MACs will be given IPs, and thus allowed to connect to the network. You're way overcomplicating something.

MAC filtering gives a false sense of security because it's easy to spoof a MAC, but that's about it.


As for the OP's issue, if you don't see any unauthorized clients on the list, and your usage isn't abnormally high, I REALLY wouldn't worry about this. Are you sure the laptops in question are "off" rather than asleep? Maybe they have some low-power mode where they stay connected to the WiFi for WoL purposes or something. Or, it's possible your phones or some other device is just seeing the wireless and pinging it but not actually connecting and that causes the light to flash.
