Thread: Irregular Disconnection with UT300R2U

Hi,

From couple of day I am experiencing irregular break in BSNL connectivity. I have UT300R2U modem which I purchased two years back from BSNL. This is connected with the Linksys WRT54G. I am unsure if the issue is with the Line or the Modem. When I am facing this issue I observe the LED indicator of Ethernet keep blinking and DSL and Internet indicators are not glowing at all. This continues sometime for over an hour and I am disconnected. However, sometime I observe all the indicators on the modem glows continuously this is the time I am connected and keep that way for couple of hours and suddenly something happens and I get disconnected. I tried troubleshooting by connecting the modem directly to the PC and eliminating WRT54G from middle. Also I switched from PPPoE mode to bridge mode but I still end up in situation. I am hoping someone will help me to understand this.

TIA,
Shiju

This may help

Thanks Meetdilip,

It seems the downstream numbers are excellent. Not sure if it is with the upstream numbers. Also, I can only connect to the 192.168.1.1 when the all lights in the modem is glowing and internet is connected. otherwise I cannot even take this reading.

Try mode as GDMT and check.

Hi Meetdilip,

I have changed it GDMT and it still disconnects - This is how my connection status when I am disconnected. What else I can troubleshoot?

I have also noticed an AC power from the modem adaptor do you think it might be because of this?

Do you hear a hissing sound / or any other disturbance while using land line ?

Tried another modem ? It may solve the issue if it is modem related.

@shiju
Check the modem log.
Check the Lease time shown in ipconfig /all data
or recheck "Always On" button is selected in WAN page.
Any setting for Power saving in the ethernet card

similar to Beetel 220BX hardware
Open modem settings.
retype 192.168.1.1/look.html

Thanks for the replies I guess I have figured out what is the issue. I have changed my BSNL modem adaptor with the Linksys WRT54G Adaptor and it has been worked for the 2 whole day. Only bad thing is I am out of wifi now - atlest I have constant internet connectivity -

The BSNL adaptor was 10v~550mA and Linksys adaptor is 12v~1A still linksys adaptor works. I know nothing about electronics but I checked with all my local shops for the adaptor with both specification but non of them could glow the power button of the modem.

I checked with the ebay for the adaptor but it cost more than the BSNL modem or wifi router.

Now a days transformer type PSU are out of date .
You can get a switching adapter compact PSU rated 110-240V A.C ~ INput
output 12V D.C = 1Amp with D.C power plug Inner marked +ve etc.
Right now:
Netgear WGR614v6wifi router is running on this type output 12V D.C= 1 Amp
2.
One make LPP( made in India) In 220-230V AC~ 20mA output 9VDC= 1000ma used for another SMC wifi router without any problem.
(heavy transformer type Plug in)

Delhi make D.C adapters ( old model) may be available with marked MRP Rs 400/= on the box for Rs 250 or so!!! . check out !

we are likely to get SMPS power supplies 12V DC, with 1 , 2 or 3 amps at a price ranging 150 to 250.
one 'silicon' brand is being made and sold in India. http://www.siliconindia.co.in/adapters.htm

Thank you!

I got an adaptor for 250 Rs with a 6 months warranty I am back on wifi
