Thread: D-Link 2520U disconnects when idle

I just bought a new D-Link 2520U for Mtnl broadband and it works well. But whenever the connection is idle, after a certain period of time, the router disconnects (all LEDs still glow, though). I have to reboot it to get it working again.

Now, I've read some idle time setting routers come with but I can't find it. Any help would be appreciated regarding this.

Thanks!

Instead of restarting, you can click on the network icon in the taskbar and click Diagnose and Repair

Check in WAN page where you enter your USERID PW.
( Presume connecting in PPPoE "Always On" mode userid/pw stored in modem).
In computer:
Start RUN type cmd Ok
new window.
type ipconfig /all
Report the lease time shown.

I wasn't trying to sound smart or anything. What am I supposed to do in the wan page? I honestly don't know.

Rechecked ipconfig /all in my set up.
Lease time appears for the WLAn network and not for LAN.

Another ipconfig /all data with lease time.

Check the Power Management option in the LAN card.
Presume you click the Icon(LAN) ( with yellow mark )as seen in Taskbar.
confirm.

My modem 110BXI( almost ) same as DSl 2520U
See link WA3002_g4 also for screen shots ( less wifi pages )

In Power Management, the option allow Windows to turn this device off to save power was checked. I have unchecked it. I'll report back if this doesn't solve my issue. Thank you very much.

Edit: Disabling the power settings has delayed the disconnect by some time but it still happens

D-Link DSL 2520U

From Device info Statistics ADSL
report mod mode selected SNR Attn values.
( Uncheck adsl2 + button in DSL menu )
Also In management you can disable tr_069 client if enabled.

Check the system ( modem log) when disconnection is felt.
What is the freq of disconnection now ?
every hour 2 hours etc.
