If you are using BSNL broadband connection then you may have experienced a peculiar problem of username in the modem settings getting reset to 'multiplay' for unknown reasons. Due to this, Internet LED in the BSNL modem keeps blinking and you are unable to access the net. This shows up as Authentication Failure in PPPoE protocol status. To see the status of PPPoE protocol status and resolve this issue,
- Login to your BSNL modem/DSL router typing 192.168.1.1, which is BSNL DSL router IP, on your browser and username : admin.
- DSL router configuration window opens. On the left hand side of the window, click on WAN in Device Info menu. Check the first row(VPI/VCI - 0/35, Protocol - PPPoE) of the WAN info table displayed. Below image shows the status in normal working scenario. If the username is reset, Status column in this row displays Authentication Failure.
- To resolve this error, click WAN in Advanced Setup menu. WAN Setup table appears. First row in this table displays settings for PPPoE(VPI/VCI - 0/35), click Edit at the end of this row.
Clicking edit takes you to ATM PVC Configuration window, where you need to make sure that the value of VPI is 0 and of VCI is 35 and UBR Without PCR is selected as Service Category. Click Next button after the changes(if any).
- After clicking next, Connection Type window appears. Make sure that PPP over Ethernet radio button is selected and LLC/SNAP-BRIDGING is selected as Encapsulation Mode. Click next.
- After clicking next, PPP Username and Password window is displayed. Enter your Username provided during installation of the BSNL broadband connection by BSNL guys and password. Enter PPPoE Service Name as dataone and select AUTO as Authentication Method. Check Bridge PPPoE Frames Between WAN and Local Ports(Default Method). Click next after that.
- Network and Adress Translation Settings window appears. Make sure Enable NAT and Enable Firewall check boxes are ticked. In Enable IGMP Multicast and WAN Service, see that Enable WAN Service check box is ticked. Enter Service Name as pppoe_0_35_1. Click next.
- WAN Setup - Summary window appears which gives the summary of settings you just made. Click on save which opens a WAN Setup window(2nd image from top in this post), where in you need to click the Save/Reboot button for your changes to be reflected. Once the modem/DSL router comes up, you should be able to see Internet LED on that is stable and is not blinking. Now, you should be able to access the net.
Note: This problem was showing as Authentication Failure in WAN status previously. Recently, I observed even though WAN status showed PPPoE protocol status as Up, I was not able to access the internet. I found that username had been reset to multiplay and after changing the username, I was able to surf.
P.S: The procedure explained above to resolve BSNL DSL Router Username Reset problem, is the one I follow to resolve it in UTStarcom ADSL 2+ Modem/Router, Model No : WA3002G4 got from BSNL. I am not sure whether the same things apply to other DSL Router models provided by BSNL. Also, note that after change the username from 'Multiplay' to yours and reboot the modem, Wireless settings would have been reset, which need to be setup again.

Manoj has informed that the same problem occurs in UTSTARCOM UT300R2U modem(Type I), provided by BSNL.
