DSL & Cable 2 computers one network

**salem69usa** · February 5th, 2004, 02:20 AM

Im curently running 2 xp computers through linksys router on cable. One computer is running my ftp server and p2p program. The other computer I do every thing els on includint the internet and lots of webcaming. Aso u know that means that both computers are shaering the band with of the cable. This is causing problems with the webcaming. for the ftp is always uploading. In a few days I will have a dls internet aslo. What I would like to do is have one computer on the dal and the other on the cable. That in it'self is not a problem. My problem is I still want to have the 2 computers on the network for I do a lot big file transfers between the to computers. How can I have each on there own broadband internet and still network them toghter.

2 network cards in each computer. One network card direct to it's respective modem, then the cards that interconnect each computer should be on a different network (different range of IP's)

Put each external connection to each seperate computer rather than the router ? ... Or just the 'dedicated' one direct to the machine with the webcam, rather than the router & keep sharing the other ? It will depend on what connections everything has ..

Security wise though with a p2p proggie running this doesn't look good .. but then again it didn't in the first place

This is your best/cheapest option

Great, I figured there'd be a way. Belive it or not but while bed last the same thought about the 2 nic card came to mind. also I was wondering (and so I wouldn't have to invest in 2 more nic cards) could I run each computer and there modems with the usb and just leave the router to tie the 2 computers toghter. If so would the usb slow down the internet enought I would notice?

Well considering that you MIGHT be getting 3mbps from a connection (probably more like 1.5mbps but we'll just say 3) and usb 1 has a bandwith of 12mbps and usb 2 has 480mbps I think it's safe to say you wont experiance any slow down. The only slow down that MIGHT make a difference is that you have to run the software (check out the other dsl thread here for a generic fast pppoe client). In all reality you will not notice it. Cheers.

ok thank you for the fast responses. Looks like I will be able to do what I need. I will try it out with the usb method and see how that goes. I will look for this thred u say to check out (check out the other dsl thread here for a generic fast pppoe client). U all have been a big help. By the time my dsl modem gets here tomarrow I will be ready and up in a few. Thanks .

Despite what Gollo says about bandwidth - Stop, rewind !! ... err usb modems demand a fair bit of cpu power

, besides 'the how fat is my pipe considerations' ... NICs generally have circuitry to deal with a lot of network traffic within the card, without any cpu involvement - I can't think of anything usb which does, that needs to talk to the cpu each time ...

Well I don't know any ISPs using usb modems .. at their end

A 2nd NIC only costs $15-20 - I'd spend it

maybe I'm reading this wrong, but can't you just get a second linksys router for your new DSL connection and then connect the 2 linksys routers thru a crossover cable or uplink port? (as described here)

set one router as 192.168.1.1 set the other as 192.168.1.2 then give your PCs ststic IP addresses of 192.168.1.3 and 192.168.1.4 and configure each with a TCP/IP default gateway of the router you wish it to use.

that's certainly doable and also doesn't physically tie down any computer to a connection. if DSL goes down, he can simply change the gateway setting and get out through the cable. plus there is a lot of scalibility in this solution as well. and cost wise it wouldn't be much more than purchasing 2 more NICs anyway.

having to do everything statically sucks a little but not enough to justify the cost of one of those load balancing routers.
good thiking craigmodius!

**craigmodius** · February 6th, 2004, 11:48 AM

it works like a charm where I work so I have a dedicated DSL connection strictly for the web server ( and me too

)

only difference being that at work the linksys routers uplink to switches instead of eachother.

plus you can specify more than one default gateway in order for a good fail over.
and this guy has only 2 PCs on his network so to me it seems like static addressing is extremely unnecessary. (Maybe if there were 200 PCs.)

**salem69usa** · February 6th, 2004, 11:51 AM

YES thank you craigmodius for that input and link. By doing it that way I won't have to run 2 more nic cables also. I do have one short cable to link the 2 routers toghter and that way I wouldn't have to relocate evey thing or run "More Wireing" around an already wire runed apartment. and as someone said the cost of the router is no more than the cost of the 2 nic cards. If the usb would have put more load on the cpu it might have caused me more trouble than I realy wanted.

Well I gues all I can do now is waite till the DSL modem gets here to see how it all goes. If it 's not here today should be here Monday. Un till then I will try to see is I can figure out how to tell each computer which gatway to use for internet.

Thanks again all u are

In all honesty if you want a really sweet solution you should get a load balancing router. Most of them will let you dedicate the connections to certain computers if you want or use them both together to get even more bandwidth. Another nice thing is that if your DSL or Cable modem goes down, you still will be able to access the internet w/ both computers w/o setting up internet connection sharing. I believe there is also a linux distro that does the load balancing and such if you want to put 3 nics in it. I know several people who have load balancing routers and love them, granted they work for the cable company and get better prices than we do. Here's one on tigerdirect.com

We are putting one of these in our shop later this month. Will be using DSL and Cable.
