Thread: DNA-A211-i moderm is restarting frequently

Hi,

I have a BSNL broadband connection and I am using DNA-A211-I modem by ITI (Semiindia). I have been using the modem since the last eight to nine months and had no issues until the last week when my modem began giving me trouble. My modem works fine for sometime, but after a few hours, it starts restarting, i.e., the power LED, INET LED, DSL LED, WLAN LED, and Ethernet LED all go out for a few seconds and then they come on again. This disconnects my internet and I have to wait a few minutes before I can start browsing again. I have to be online for at least 8 to 10 hours as part of my job and I am finding it a bit irritating to get disconnected so frequently. Can anyone help me in this regard.

1. Check your splitter. If faulty make a replacement.

2. Post your SNR and attenuation values.

The splitter is fine. My BSNL connection is 10 years old and we recently changed the connection wires from pole to the splitter (Junction box). Hope this info is useful to you. Thanks again.

.Any changes, like an extension telephone added ? ( for nine months OK )
2.
Could be a power supply adapter problem ( few hours ? )
3.
Problem started after Motive upgrade ?
4.
Please post Statistics adsl data showing
Mod selected snr attn line rate rate data.
5.
Check whether TR_069 client box is enabled . Uncheck it.
6.
see first link below for more info about dna A211-I
7.
A software upgrade is also another option. Links available.

Hi

Thanks again. I borrowed a Telenet TNDLS 2120 modem from a friend and hooked it up to my connection. It is now working fine without any glitches. I think the problem, as you said, lies with the adapter. I will check the power connections and get back to you.

Please try In DSL menu page of modem
GDMT Uncheck adsl2 + box
SAVE reboot. wait for 2 minutes
9.
Only SNR/ATTN line rate rate data needed.
you may edit and delete rest of the data.
