quick DSL question

[Warthog]

Ok, DSL runs through your existing phonelines, right?

I have two comps in different parts of the house, both next to phonelines. If I had a DSL modem for both, they could go online simultaneously, right?

I think I'm getting DSL soon, so I need some answers http://sysopt.earthweb.com/forum/smile.gif

I dont think you can have 2 modems connected to the same line what you would need to do is network the 2 togather and use a internet connection sharing program

[tonym]

Warthog,

1 Phone Line = 1 DSL Line.

You can't have multiple DSL connections on a single POTS line. And you cna't have multiple DSL connections on youe single phone line.

So for all practical purposes, 1 DSL Line = 1 Computer!


Sorry...

Thanks guys!!!

I didn't think the one phone line thing would work anyway. http://sysopt.earthweb.com/forum/smile.gif

So....

I should get two Ethernet cards and run a cable between each? Oops, this is turning into networking....just a quick question http://sysopt.earthweb.com/forum/smile.gif

Are current "consumer" DSL modems capable of connecting to a 10BaseT network? IE. Two computers connected to a hub, then DSL modem is connected to the hub as well, thus giving internet connectivity to both systems? If so, this would be the best alternative.

The reason I ask this question is simple, they are all different!

Warthog, you can get Intel Wireless network controllers so that you do not have to run network cabling in your attic. They are rather expensive the last time I checked thou. If the DSL modem your ISP sells you will not connect to a hub directly, then Internet Sharing through your OS is the only alternate route that I'm aware of. Although this may work rather well, the internet sharing on your "server" machine can become quite resource intensive.

You might find Etherloop, a type of xDSL, to be rather interesting. Mainly used for large cooperations, it is capable of transmiting and receiving large packets at the same time, with a total bandwidth of 8megabits/sec up to one mile (I believe). I've been using Etherloop for 2 1/2 years (since testing stages) and it is basically a WAN ( Wide Area Network ) that runs a DSL speeds. Check it out at www.etherloop.com (http://www.etherloop.com) ..

EDIT: www.etherloop.com (http://www.etherloop.com) must be having server problems. As an alternate website, you may want to check out ..

yeah you can run 2 computers off of one DSL line, its one of their selling points, as opposed to a cable modem (which will charge extra for additional computers to be connected) you can run your dsl to an ethernet hub and the run that to up to 5 differenet computers, i have 2 right now both connected to the internet and get great dl speeds with both comps via one dsl line.

[tw1112]

You could run DSL off the same line with two different computers and modems, but the thing you need is another IP address. The thing is, technically, when they install dsl, it gets opened to all the lines in the house that have the same phone number that they installed it on. So, if you have dsl and you want a phone using the same line, you would have to plug in a dsl line filter. For your computers, see how much it would cost per month to have an extra IP address. If you dont want to go throug the networking and stuff. Not too hard though but just if you would like to go without.

The reason for 2 IP's is because technically 2 computers cannot be using the same IP address at the same time because it might cause conflicts, well actually it will cause conflicts. This is only when there is NO network running...so think about which one you would like to do. I would choose networking....that's what I did. Bought a Linksys Router and then just connected both of my comp's. That way if any of your friends come over and want to use it, you can just plug in another ethernet cord and that computer would be automatically using your dsl.


Oh, almost forgot. If you do get the Linksys Router, you could link up to 254 other computers to your one dsl line. You would just have to buy another network hub and it would connect to your router then your computers will connect to the new hub. Just FYI...

Technically, you can connect as many computers to your DSL that you wanted (thou, remember you would have to have the available IP numbers). All you would have to do it stack the hubs.

I would defently network. One of the main advantages of networking is file and print sharing between your networked computers. This isn't as hard as some imagine that it is either.

[SysOpt]

Even if you have a dynamic DSL account you can run as many computers off the line as you want. Connect the DSL modem to a router, and connect the router to as many computers as you want (via hubs or switches). Here's one that will work for PPPoE (dynamic) or static DSL:

http://www.us.buy.com/retail/product.asp?sku=10235958&loc=101

That one supports up to 253 users/computers. It's essentially your own DHCP server. It gets it's IP from your DSL ISP, then assigns dummy IP's to your systems.

[Warthog]

Thanks for the ideas, Mungla!

Cool, I'm very glad it can work, lonestar!! http://sysopt.earthweb.com/forum/smile.gif

GTE in Plano TX allows multiple IP addresses off of one basic account. My friend just hooks his hub straight up to the DSL modem, and uses both his and his wife's computer. He asked them ahead of time and they said they did not care how many IP addresses he requested.

[yaroa]

Warthog, follow Sysopt advice above, you'll be glad you did.
I have my daughter's and my computer connected to this router, since November of last year, and not even once have I had trouble going online with both computers at the same time, although, for some reason it slows down a bit when she is logged to napster.
All you need is two NIC cards and some cat 5 wire, and you're set to go.

[Warthog]

The router can also be configured to block internal users' access to the Internet

Does this mean what I think it does? You flick a switch to one of the comps and it doesn't get i-net access? My dad would like that for HIS comp so he can limit her usage (chat freak) http://sysopt.earthweb.com/forum/smile.gif. I, of course, am the responsible one http://sysopt.earthweb.com/forum/wink.gif.

Anyway, thanks for the link, Scott. That sounds like an excellent idea, especially if I get more comps, I can just hook them up to that.

What about the cat 5 wire? Where do I get that? Is it some sort of special wire, or what? Excuse my ignorance http://sysopt.earthweb.com/forum/smile.gif

Warthog, CAT5 is the primary cabling used for network cable. Typically, when your networking your house, you would buy CAT5 in 1000' boxes. You can get 1000' of cheap CAT5 for under $100. But, if you plan to be doing 100BaseTx or even Gigabit-over-copper networking, you need Enhanced CAT5.

If your interesting in phone line networking, check this link out: http://www.egghead.com/category/inv/00036305/03278140.htm

Although I've never tried this method of networking, I've heard pretty good things about it. I wouldn't recommend you use this method unless you find it impossible to run CAT5 to both of your systems. Also, I do not know how the DSL running on the same cable pair as the phone-networking would work. It might work ok, and they might have conflicting frequencies-you never know.

Hey guys, tw1112 said that when you add DSL line filter you can use your telephone too.I'm asking how much off bandwith is reduced with that solution because I have telephone freaks at home.

[yaroa]

Telephone usage does not affect your computing, something to do with both signals having different bandwidth.
I read this when I was getting dsl, several months back, so my facts might be a little be distorted, please feel free to correct me http://sysopt.earthweb.com/forum/smile.gif

[djurom]

Yeah, you're right.I did some reading and it's working on different frequencies so no one is affected by it's usage.I have that kind of setup where I work.

[stodge]

Follow what sysopt says.

You can have a whole network of computers through a DSL connection, but you need some means of sharing the connection; Linux + IP masquerading works a treat.

[Warthog]

Cool! Thanks guys!

I have a DSL line from Speakeasy.net and I currently am running two pc's off of the same account.They provide you with two ip's and two emails for 59 a month.I am using a linksys 5 port work hub with will allow you too split it five ways if you have five seperate IP's.Good luck
