Solve : Connected Devices?

Answer»

I would like to check what devices are connected to the router, and I think the page shown below is the correct place to check?



My questions:

1. What the "EXPIRES In" column means?
    Sometimes there are two entries for the same device with different time remaining.

2. Why the wireless devices are listed here instead of "Wireless Clients"?

Thank you.1.  Any connected device is given a lease for a fixed period of time.  The amount of time is somewhere else, looks like it could be 24hrs.  That doesn't mean that the device is still connected now.  It could be the 1st two on the list never expire (i.e. expires in 0 sec).
2.  The Devices are the Clients.  Doesn't matter if they are wireless or wired, all are clients.It means when a device is connected, the clock will start counting down from 24 hours. Even after the device is disconnected, the clock would continue to run.

1. Why would some devices have no expiry time?

2. How can I know which devices are currently connected?

3. How can I know which devices are connected via LAN and WLAN respectively?

Recently I've noticed that one or more wireless devices are draining the bandwidth of the internet connection. If the WLAN is turned off, the speed is normal, but if it's turned on, it'll drop drastically. So I'm trying to monitor and figure out which device is at fault.

Btw, is there any utility tool that can show the bandwidth usage of each connected device?

Thanks !


D-Link DSL2730U is a combination modem & router, probably provided by your ISP.
It appears that this model is not sold or used in North America.
Are you located in Iran or India?
User manual seems to be multi-lingual.

My modem looks different from the one in your link.

Anyone?Referring to the logs, see this http://support.dlink.com/emulators/dir601/100NA/support_internet.html on Network Settings | DHCP lease.
Advanced IP Scanner for connected devices http://www.advanced-ip-scanner.com/
Disable QOS option if available on your Dlink router model. Certain torrent downloads and streaming usually eats up bandwith usage. There might be a section in your router that could PRIORITIZE certain programs bandwith usage, please check the manual.Hi Jason,

Thanks for the links.

Now I understand the DHCP lease. Just wondering why it keeps the expired LEASES in the list.

As for the Advanced IP Scanner, it will only show the currently connected devices, right?
However, it doesn't seem to show the bandwidth being used by each connection.

If I disable the QOS, would I be totally unable to stream video e.g. YouTube?  So, any recommendation for utility tool that can show the bandwidth usage of each connected device?

I've tried the Advanced IP Scanner suggested by Jason but it doesn't seem to display bandwidth usage by individual device.
 
Many other bandwidth monitoring softwares are only monitoring the usage on the PC itself and not other devices on the network.The only way you could measure the bandwitdh used by individual devices if your router doesn't support this directly is to have a physical device that sits between the router and devices to monitor all the traffic that passes through it.  You could do this with software on a regular PC or by using a specialised network appliance, however this isn't a small task and would be more effort than it's worth for a home user.

Unfortunately you can't simply measure it from another connected device as the traffic from the other PCs will never be seen by this device.
