The settings are stored on a piece of memory called NV-RAM (Non-Volatile Randon Access Memory). It will retain the settings and is not affected by power losses. It can only be reset when we want it to be. So your settings and preferences are all safe.

Will the Modem not get a hard reset. Does it mean that all settings are lost?

It is easiest to forget that anyone mentioned 'resetting the modem'!

Think --- dropping the line and making a new connection, or just 'disconnect and reconnect', which will certainly happen if you turn off, and turn on again. Best give a minute or so before turning back on though!

Nicely written Sam. It's almost a documentary material, the way you have narrated. :-)

Anyway, It's good that you were able to reverse the charges. I don't understand what is preventing TRAI from coming up with a policy that restricts ISPs from charging anything more than the unlimited rate for that speed. In other words the maximum they can charge for a particluar speed should be its unlimited package rate. I'll see if i can write to TRAI through their website.

Guys, that this is properly called a router - not a modem. Output from that thing goes into your network interface, right? That is why I call it a router. Ok - does not make much of a difference to us, so we willl continue to call it a modem.

"Resetting" that router/modem means poking a sharp narrow object (like a needle) into a hole somewhere on that thing. It will 'reset" everything to factory defaults. All user settings - like passwords, usernames (which are specific to the user and / or the ISP) will be lost when the modem is reset. THis is a bit like removing that mod-chip you put on top of your ECU. (Think of removing pete's or replacing your upsized tyres for the default profile tyres which were fitted by your car's manufacturer).

As to getting things done, remember that in a govt/semi-govt office, functions are very clearly defined and people will not poke into what is supposed to be done by a colleauge. So, when you asked (especially by a superior official) to meed Mr. X, you should look out for Mr. X; and there is (usually) no need to waste time explaining to Shri Ran Domman why you want to meet Mr. X.

Umm.. I am not as computer literate as Samurai and the others but I do know that this is properly called a modem.
It is a device used for MODulation an DEModulation of the internet signal from the phone line. That's why it is called an ADSL modem. A router or a switch or a WLAN device is probably what the modem would then connect to.

What you get these days is a Modem+Router in one. Perhaps one of the techies here can explain this more precisely, but in simple terms to me it means that the modem connects you to the net and the router distributes the connection to one or more PCs and other internet enabled devices in your home network?

Sam, what are your thoughts of sending this to "Office-Office" ? They might even make this an episode...except for the happy ending.

Sam the BSNL ADSL "modem" has multiple interfaces(USB and ethernet). So its technically a ADSL router

A modem translates digital to analogue and analogue to digital. ADSL is all digital. That's why it is not a modem!

It is more than a router, which takes traffic from one network and, where appropriate, routes it to another network, because in your house you have an TCP/IP Ethernet network, and between the phone, the exchange, and the internet you have a different physical protocol. So that section of the box is a protocol converter. I think there may be another techie name for that, but, in this instance, it isn't 'modem'!

This is what I have
D-Link DSL-302G ADSL Combo Modem

The company that manufactures it calls it an ADSL combo modem. Combo as it offers the convenience of both USB and Ethernet.
But it is called a modem. Else the company would have called it something else no?

Huh?
Buddy you are very very wrong.
ADSL is not all digital.
You cannot transmit all digital signals like this over the phone.
There is a D2A converter sitting at the exchange, and inside your ADSL modem there is a A2D converter.
There are some ADSL modems which are not ADSL routers. They have just one interface(USB). So in one end comes the telephone line, and at the other end it connects to your PC using USB. Such devices cost around 10-15$ to the manufacturer.

Sam modem is a very common name, and is used for ADSL routers also. Its more of a marketing thing. Most of these "modems" in the market today can function as routers as they can do "routing too". Many times a true modem, and a true "router" from the same company can have all the internal circuitry and software same, just at the enternal space the cheaper model may give just a USB out and not an ethernet out or vice a versa.
D-Link DSL-302G ADSL Combo Modem
If you open that page you will see the line
"Support 2 computer simultaneously".
That means on one ADSL line it can "route" the traffic to 2 computers. So what does it make it? An ADSL router.
But if they call this one an ADSL router, who will buy the more expensive models with multiple ethernet ports etc.,
There are people who want to buy something called a "router" just for the heck of it

Well, can I be forgiven for thinking that ISDN and DSL are digital services?

We are nit picking here, but:

DSL IS a digital "service" that is provided over analog "physical layer".

Modem creates an ATM channel over unused frequencies in telephone line. ATM is digital, signals in telephone line are analog.

Modem translates between 0 and 1 and electrical signals on telephone line [in 30 kHz -- 1MHz band].

So it is sort-of on of those depends-how-you-look-at-it questions?

I don't mind being wrong. Just... I was convinced, now I'm confused. I had always thought that, as well as being outside our hearing frequency, it was, in principle an entirely different means of transmission to the singing tones of an analogue modem.
