Thoughts about adsl and modem's etc


When browsing the LQ forums I notice that apart from the "tip's & trick's" type posts, most of the questions seem to be causing a fair amout of hair loss and/or nervous breakdowns amongst we types.

I am lucky enough to have an adsl connection. Unluckily, I had this facility before I embarked on my cause of trying to get rid of micr0$0ft and learning linux. Subsequently, I have experienced a fair amount of the aforementioned hair loss and other stress related problems when it comes to my adsl connection under linux.

I opted for mandrake as my distribution of choice, mainly because it was reputed to support my adsl modem "out of the box" and was relatively "newbie friendly" - the modem being a "piss poor" alcatel speedtouch usb.

Now, I have to admit, that the only reason for me calling the speedtouch piss poor is because of the hassle that it has caused me in getting it running properly under linux (it was excellent under wind0w$).

Over the last weekend, I have had what I consider to be a considerable "linux success". This has involved replacing the speedtouch usb, with a SAR110 modem/router and an NIC ethernet card.

This could sound relatively daunting to some, but in truth, opening the PC case and plugging in the NIC card, setting up the modem/router has been pretty basic.

What this results in, is that I still have my adsl connection under wind0w$ XP, I can reboot into mandrake, if the network (i.e. me, my pc and the router/modem) was enabled, then as soon as the boot into mandrake has completed, then I am still online. If the network was disabled, then when I get to the linux, then I will be connected. Etc, etc. It allows me to flip back and forth without the wait for the speedtouch reinitialising everytime I swap OS's and various combinations of connected/disconnected, mandrake/wind0w$.

That is quite an improvement as far as I am concerned.

Also, as I recall mentioning in other posts, it means that I have completely nullified the posibility of making another linux config change that kills the speedtouch connection (/usr/share/speedtouch/speedtouch.sh line 150 command ?RETURNED =0 command command not found) that required me to reinstall the whole OS, which was the only way I found of repairing thing problem. It has taken the adsl connection and firewall out of the hands of the OS and leaves that up to the router modem.

I should point out that in between sessions online I am still "disabling the network", though this is only until I can ensure that I have got the modem/router's hardware firewall set up correctly. the importance of which cannot be understated, even taking into account the relative "safety" we linux users enjoy compared to wind0w$ users! - and one of the hardest things to get a grip of, has been firewalls in linux, it has been the thing that killed my adsl connection more often than anything else I have been trying to do.

The morale, if you have/or are going to have access to an adsl connection, then read up on the various modems, methods of connection, etc because any deal offered by an ISP that offers a modem will probably be for a USB modem, and with my experience, I would say that to go the "ethernet route" could save you considerable heartache. The adsl guide was one of the better sources of info that I eventually found - A bit UK biased, but as far as the news articles go, but it should be valid advice where equipment is concerned.

To those of you who nagged me not to bother with USB for my adsl connection (not quite sure but for some reason zlinuxz comes to mind but I don't recall if it was him? who kept teling me to dump the USB modem, or somebody else), anyhow, I apologise if it ever sounded that I was doubting your wisdom.

Hopefully, my rambling thought's may be of some use

regards

John

p.s. the other thing that the modem/router option will allow me to do, is to change/try other distributions without having to worry as to whether my modem will be compatible or whether I will have to spend hours trying to get it configured.

Don't forget, you can also now do ftp installs, eg SuSE 8.1 - impossible with the Alcatel.

From what I understand (which isn't much!) there is now quite a lot of stuff that I should be able to do that I couldn't with the "turquoise cow shit".

The only stopping point is what and how !!!

Having never used ftp, I only have the vaguest notion what it is/does

Perhaps I should change my user name to dumb s**t!!!

I have to say, just for balance, that I've had no problems using my Alcatel modem with Windows and FreeBSD (although I suppose there might be different issues with Linux, I don't know...) I had to download a driver module for FreeBSD (which you can also get for Linux and a few other OS), but it all worked pretty smoothely.

Not to disagreee with the original poster - just saying that using a USB modem in *NIX is a viable option.

Anything - well almost anything - that reads hardware router with ADSL that connects to your box with ethernet is no problem.Some guys here have a problem with this - why? - don't know;probably too easy

Sorry if it sounds like I'm being picky llama_meme, but I did point out that I was being a little unfair to say that it is totally piss poor, it isn't, but if you read the entire post, I said that it worked excellently under wind0w$. Of the 3 distro's that I have tried, 1 suse and 2 mandrake, only the current mandrake version (9.0) was easy to configure.

Then there was the slow shut down and boot sequence with both the linux and wind0w$, the 20 or so second initialisation with every change of OS, what a drag!

Not to mention the "I/you have just killed your speedtouch connection by screwing up the speedtouch.sh file" message that I would get everynow and then. The only satisfactory conclusion to that one, was the OS re-install, which was a total pain. Yes there may have been an answer that might have prevented it, but I'm buggered if I could find it.

Hence my arrival in the "Pro router/modem/ethernet" camp.

You only have to search here at LQ to see how many others have had aggrevation from the speedtouch usb - yes I would grade it as adequate, but no more.

Your serve.

regards

John

p.s. the original post was my thoughts in respect of possible suggestion to anyone who is thinking of getting an adsl modem that will be used on more than one OS, though if you have always got on with yours under both wind0w$ and BSD then more power to you.
