How do you think a BSNL modem will work with Airtel broadband, obviously the configuration settings are different.

Really? Do you guys think this particular modem is service provider dependent? I infact spoke to the Airtel CC and had a technician came over to my place. He checked and blamed it on the power adapter and asked me to replace it to 12v one from the 6v that BSNL provided. Although i was not convinced i still checked with the 12v adapter but it did not work.

I'm going to check the modem with a BSNL connection tommorow to make sure it is not broken. I shall post a message after the check. In the meantime if anybody else has any other ideas please do post.

thanks

The modem is not Service Provider dependent, as long as the connection technology (e.g. ADSL, DSL etc.) is the same. What @zaks is referring to is the SP-specific configuration of the modem, which specifies the connection parameters and such.

You sure you did not see a puff of bluish-white smoke when you connected the 12V adapter? Hard to imagine what that "technician" (a h**jam, most likely!) was thinking when he told you to use a 12V adapter, when the original adapter was 6V! The sticker on the Modem will tell you, as will the user manual, what voltage is needed at the PS socket.

1. What make and model is the modem? You can find the modem manual on the 'net, OR just request the nearest BSNL service center to lend you a copy
2. Which LEDs are always ON? That happens for a short while at the start
3. The yellow and green LEDs in the Ethernet socket in your laptop should light up shortly after you connect the cable (the network connection will be detected by the laptop OS only when this happens). Do they? If not, quite likely the modem IS kaput.
4. Only when there is a successful network connection (don't bother about IP address at this moment) that you can proceed to get to the Admin screen in the browser (usually by http://192.168.1.1)
5. The manual will also describe the method to do a hard reset on the modem box
6. You need not have a successful connection to the service provider to check the modem - only the LAN connection is enough at the start

Thanks DerAlte,

Interestingly the adapter provided by BSNL is 6v but the sticker in the back of the modem shows 12v. That's the reason i checked with the 12v adapter without hesitation -- no puff of smoke i saw :-) .

The make of the modem is UTA starcom -- i did lot of searching on the web to get the manual but i couldn't find one.
The LEDs at the back of the modem is always on -- won't go even after a while.
The laptop does not detect the connection -- no LED is lighted at the ethernet port
I'm just trying to find the way to hard rest the modem i haven't been successful so far.

I have used an Airtel modem on a BSNL Line - worked just fine.

I connected ,my Netgear Wireless router to my Airtel DSL modem. Im wireless now. I can access my net with my laptop anywhere at home. Same for my HTC touch. I can connect to the net even from the ground floor. (I stay on the 4th floor). It rocks!!!!

Not connection problems, but it's about speed.

Have a Type-4 Huawei modem on my BSNL connection. I feel the connection is slower than what I had with the old Type-1 modem. I have browsed through the config, but dont seem to find any problems. Only one desktop connected to the modem - no other connections, wire-less or wired.

Any ideas ?

[DerAlte]

Check if the speed increases if you disconnect and reconnect (from the Admin screen). Also, on the second link in the Admin screen menu bar on the left ('system details' or something), check the connection speed and noise figures.

[condor]

The parameters dont look bad. Notice this problem after getting a the Type-4 Huawei.

PARAMETER Down-strm Up-strm
SNR Margin (dB): 22.1 * 29.5
Attenuation (dB): 18.5 * 6.1
Output Power (dBm):8.0 * -7.2
Rate (Kbps): 2045 * 255

I use a Netgear wireless router at my in-laws place ( Forget the model number ..the basic Rs1750/- model ), and a linksys WAG200 wireless modem cum router at home. Strangely I find that the signals from the Netgear is very very strong - even our cousin two houses away uses it to browse. However the Linksys at home is rather weak - Its kept in a bedroom and I get ony 2-3/5 bars in the dining room!

Wonder why!

DerAlte : Check if the speed increases if you disconnect and reconnect (from the Admin screen). .

@DerAlte, the speed is better : but only on wireless mode. Got my laptop connected, and this is much better than the speed that I get on the laptop. No config changes on the modem.

[DerAlte]

That is something I have not been able to fathom: better apparent speed (apparent response = page pull down speed in browser) on a disconnect-connect. Doesn't sound logical, unless there is some DoS-type query traffic landing up on the cloud-side of the firewalls of connections which have been on longer.

I get a slightly better connection speed:
Operation Mode G.Dmt.BisPlus
Bandwidth Up/Down(Kbit/sec) 510/2043
SNR Up/Down 17.8 dB/36.5 dB
CRC Up/Down 0/0
FEC Up/Down 0/0
HEC Up/Down 0/0
Attenuation Up/Down 11.0 dB /37.0 dB

Didn't understand this part. The apparent speed would be the same whether via LAN or via wireless, no? Especially even if one assumes connection via 10Mbps LAN or 802.11b, those speeds are much higher than the connection bps.

[condor]

@DerAlte, I meant that between the desktop (connected to the type-IV Huawei with a Cat-5 mounting chord) & the Laptop (connected via wire-less), the speed's better on the Laptop.

No config changes on any of the systems / modem

Also, speed experienced on the desktop with a Type-1 Huawei was much better than what I am getting now with the Type-4 Huawei. (Type-1 is a single UTP port on the modem, Type-4 has 4 UTP's + Wireless).
