2 NIC's 2 DSL lines, one pc?

If you have two physically separate phone lines (i.e. with different phone numbers) then you should be able to use the lines separately.

You could setup one line for your normal internet surfing and if you host a server use the other one for that.

You can't use two lines for normal web surfing I don't think because both lines require a default gateway setting to get out to their respective ISPs. That would cause networking confusion on the PC.

The only way I know that might work is if you use something that lets you use two lines from different ISPs as one link. At my work we use Checkpoint Firewall-1's capability of "Redundant ISP" which lets us either use the lines as primary/backup or combine them together. At least that's what the Checkpoint guy at work says anyway.

From what I know, you can't do it with windows 2k or XP/XP pro. I believe it is possible with server editions. You need knowledge on routing protocols and linux to do what you suggest. Also, you would need a very good router one with two internet ports and two separate phonelines. Then you could do it. In short it isn't worth the hassle.

You really aren't going to be able to shotgun them with the hardware you have on hand. You with either need a much more expensive router or have some pretty good knowledge of linux and routing protocols. (Probably RIP) Even with this you still will not be able to pull the entire "combined" speed in one download as the lines are not combined. All of the requests will come from two different IP's. You will be able to get the down speeds in parralell though.

^^^this is correct...

ps you may not even be able to have 2 dsl running to 1 residence.

some areas are not equipped for such things.

Um, google for "connection teaming"

What you want is a dual wan router-you'll not see the benefit when downloading 1 file but you will when downloading 2 the same applies to uploading-you can do it with windows the os your using doesn't have anything to do with it really-
Dual wan router's are a little expensive for a real one something from one of the 12 variants of the cisco 1700 series should get you what you want...'bout a 1000 dollars or so though

Yes, but CC has a cheap alternative above compared to a Cisco product.

There's also a number of software packet shapers that mitch has pointed out as well. Lot of options, but why do it? If you're unhappy with SBC to begin with, sounds like you need to swap vendors rather than throw more money at the problem....

Yeah the extrasys is nice I'd buy that-based off price alone-If it didn't work oh well...no loss there-I didn't see link before-prolly because I typed and started reading sumthin then hit submit later on I do that alot. Wife calls me "scatter brained"

Be careful in the router you choose--some can only produce a maximum of 10/100 not serve multiple computers each at 10/100 speeds. I don't know of a software in Windows that will let you share to incoming connections--windows won't even switch to the faster of the two ( I had this isssue when I was on a wlan and a T1 at the same time). I'm sure you could use some software in Linux to use both lines, but as previously mentioned it is not the equivalent of adding both bandwidths together.

Heh, reminds me of the time I couldn't find my router so I used both the USB and the lan connection to game with a friend. It would work great for an hour with latency < 20 ms, but then it would spike to like 3000ms and I'd have to reset it... oh well, it wasn't my hardware. heh heh heh.

Well most isp's dont deliver anything above 10 mbps. In his case, 3 mbps downstream and 512 kbps upstream. So that unused bandwidth between modem lan port and the routers lan port to the computer has nothing to do with received the full 10/100 mbps when your isp isn't delivering anything near those speed.

He would either need a router to bridge the connections or be able to configure how to bridge and route the connections.
However this usually requires the isp to support the bridging for this to work.
Linksys with two dedicated wan ports There are some routers like this you wouldn't want, they just use the second wan as a fail over type of function.
I'd call SBC and make sure they support bridging first of all.

Also how far are you from the CO? That usually effects the type of speed you'll receive, if you have anything in your modem that will show you the line noise, you can usually look this up and figure out from the distance how much overhead you will recieve with dsl.
