Connect computers on different networks

September 12, 2010 at 21:14:02
Specs: Windows 7, Intel Core 2 Quad/4 GB DDR2 RAM
Here's My Setup:

- Internet from a USB Modem (ClearWire USB)
- USB Modem connected to Computer A for internet access
- ICS enabled on the modem connection to share internet with the LAN connection
- Computer A connected to a Router thru Ethernet Connection (LAN card of Computer A to LAN port of router).
- 1 Computer (Computer B) connected to router thru ethernet wired connection and a Laptop thru wireless

Computer A is sharing the modem with it's LAN card, giving the LAN port an IP of 192.168.137.1 to the Router. The Router is configured as a DHCP server, it's IP is 192.168.1.1 and giving Computer B and Laptop IP's of 192.168.1.2 and 192.168.1.3. Every computer has access to the internet with no problems.

What I want is to use Computer A as a Music/Movie server and be able to access it's files from Computer B and Laptop, but I also want Computer A to be able to access shared folders from Computer B and Laptop. How can I accomplish this?

I'm guessing illegal music and movies. Personally, I won't help somebody steal because in my eyes, that makes me as guilty as they are.

Curt, I respect and agree with that decision, but I don't think that we should start not helping people on here based on speculation of such activities. There are people out there that legitimately rip their own legal dvds and music for use with such home entertainment setups and for longevity.

This would be like me going to the MS Office threads and telling them that based on the statistics of how many copies of pirated Office software are out there in the wild that I'm not going to help them.

I hear you JRComp but.........by the OP's own admission:

What I want is to use Computer A as a Music/Movie server

To me this says point-to-point sharing software to send/receive illegal music and movies.

I figured the OP would respond and straighten me out if it was indeed a legit request. If it is, I'll help.

***edit***

I make copies of all my music CD's and play those. When one stops working, I burn another from the original. This is legal and saves me having to spend the same money over and over again on the same CD. Mind you, now that I have an mp3 player and an "auxilary" port in my 09 F150, I don't play CD's any more at all.

This would be like me going to the MS Office threads and telling them that based on the statistics of how many copies of pirated Office software are out there in the wild that I'm not going to help them.

But, if someone said, "I have a pirated copy of Office and I need a code for it" would you offer one up? I bet not.

You're exactly right. My analogy was more leaning towards the fact that nothing in the op's post alluded to doing anything illegal; or at least that's how I took it, but you said you thought it did. That's the only difference of opinions going on here, I hope you don't take offense to my comments about your post, they are not meant to be malicious.

No offense taken. :)

You've never been aggressive or offensive that I've ever seen (to me or anybody else) so that thought never even crossed my mind. I took your repsonse in the spirit it was given.

Now me on the other hand, I can, and have been both........but as far as I know, not with knowledgable regulars like yourself.......usually only with the wannabe's who are clueless......lol.........and the people who argue in the face of a preponderance of proof that proves them wrong.

Ok, let me clarify something:

This is an in-home setup, as per my setup description on the original post, there is no mention of sharing out or accessing any of my computers from the outside, so I don't see why the assumption that I'm trying to do something illegal just because I used the words "Movies/Music Server". This setup could be as well for an office sharing it's own documents or a LAN party tring to hook up computers together to play online, which neither is illegal.

Computer A is a Home Theatre PC, which I use to watch movies and listen to music thruout the whole house (This is my CD/DVD/BD player). What I want to do is put a copy of some movies so I can stream them so my kids can watch them on Computer B, which is in their room, this way they don't have to handle the CD/DVD/Blu-Ray disc and either loose them or get them all scratched up, and also control what they can watch and listen to, but also I want to be able to bring my laptop to my bedroom so my wife and I can watch movies without having to go and look for a movie and bring it and play it and then go and put it back (you can call me lazy if you want to).

I may have assumed the wrong thing, and if I did I apologize, but typically, when someone comes in here and says what you did, it means illegal music/movies/software and point-to-point sharing.

The simple solution is go with a single subnet in your home. If all computers are on the same subnet, they can all communicate with each other easily. Problem solved.

Having multiple subnets and making them speak to each other means having to have a router (or, routers) and configure static routes between subnets on the router(s).

Since you don't likely have more than 250 devices in yoru home that require IP addresses, the smart (easy) thing to do is put them all on the same subnet.

That's ok, I wasn't very clear in the first place anyway, I could have been more specific in the beginning.

The USB Modem uses a subnet assigned by the ISP, now, when I share that internet connection, it gives the LAN card an IP of 192.168.137.1 and a subnet of 255.255.255.0, which is given to the Router, then, the Router's IP is 192.168.1.1 and subnet 255.255.255.0. Computer B and Laptop are using IP's 192.168.1.2 and 192.168.1.3, with subnets of 255.255.255.0.

I tried setting the Router's DHCP servere to 192.168.137.x network, but it diesn't let me because in conflicts with the router's IP (regardless of me using 137.2, 137.3, it says the same error, unless it means that I need to change the subnet to be able to assign it a 137 IP address).

My problem is that my internet is thru a USB, not a regular DSL modem that I just plug in directly to the router and I plug everything to the router and everything shares with everything right off the bat.

Is there any way to accomplish this in some other way? If I try using a second LAN card on that computer to connect to the router, it knocks out the internet connection, unless I'm configuring the second connection wrong.

I'm thinking your "USB Modem" is a combo unit that is a router as well as a modem. I may be mistaken but without the make/model info of the unit it's hard to say. If you include the make/model of your "USB modem" then we can google it and see what it is.

I kind of need to know what exactly we're dealing with here.

Typically, a modem simply modulates/demodulates a signal and doesn't require an IP address. Every one I've worked with has an "in" connector for a telephone RJ11 jack if it's for ADSL or it has a cable "in" connector (like for cable TV) if it's cable highspeed. The "out" port is typically an RJ45 port that you plug a network cable in to that runs to the "WAN" port on your router.

Anyhow, if I'm correct and your USB Modem is in fact a combo unit, and you're plugging it in to another router, then you probably don't need the second router if the USB one does DHCP and such on the LAN side.

Reply with the make/model of the USB modem and I'll see what I can find out about it and hopefully be able to help you get everything working properly.

The USB modem is a Motorola WiMAX USB Adapter USBw 25100, for use with ClearWire.

Here's the network information that the adpater configures itself to give me internet:

IPv4 Address - 71.21.231.238
IPv4 Subnet Mask - 255.255.192.0
IPv4 Default Gateway - 71.21.192.1
IPv4 DHCP Server - 64.13.44.153
IPv4 DNS Servers - 71.22.6.13
64.13.115.13

My router is a Netgear WGR614v9 Wireless G (just in case it helps knowing, for configuring manually depending on the Ip's above)

First of all you might want to call you isp and tell them to get that usb junk out of your house. and send you a modem with a ethernet adapter. B/c you are only getting 10 megs with a usb cable you will get 100 with a ethernet but that is not the question. The easiest fix is to change the network name on the two devices that you want on there seperate network. It is very easy to do. just go to control panel System properties and change both of the workgroup names to the same name so they will be on the same network. The workgroup names are under system properties. Reboot the whole network and boom. you will be good. You can connect to the other computers on the other network if you want to. To see if it worked try to network a drive and it should show you 2 different networks with computers on each of them.

PS who cares about filesharing when i watch a commercial that says that musicians dont have money to pay there medical bill or buy there eye glasses. Then i switch the channel to mtv cribs and i say wow that ride is nice i wish i can afford one. Dont blame filesharing for revenue shortfalls when most dont even read the contract that they are signing. Look at you boss look at his office nice right. But i do feel bad for the artist especially digital music. When you have a break down like this 18% goes to artist 25% goes to credit card processing and the rest goes to the labels. It is funny that credit card companies make more on there music than the they do.

Well, my company is providing me with the free internet, because I work mostly on the go, so that's why I have a USB Modem, so that I can just plug it into my laptop, but when I'm at home I use it because, hey, free is free, and it works perfectly fine for what I need it, I don't download much, just browse the internet to search for the information I need, my wife just looks at Facebook and my kid just watches cartoons on some websites I have allowed him to watch, I don't need anymore.

The problem I'm having is just with the way the USB modem assigns IP's, I can't get around it so that all computer have internet plus share files. I'm just trying to see how to get around it so that I don't have to get a regular DSL modem.

I'm going to need to have you describe how everything is connected.

Since that's a USB modem that looks like a memory key, I'm guessing you plug it into your laptop, then plug the wired connection of the laptop into a LAN port on the router.

Is this correct?

Above you said, "The USB Modem uses a subnet assigned by the ISP, now, when I share that internet connection, it gives the LAN card an IP of 192.168.137.1 and a subnet of 255.255.255.0"

If I'm correct in how things physically connect, then you should be able to assign the router an IP in that subnet. I know you said it errored out when you tried but I'm thinking maybe you tried to plug in to the WAN port on the router. If so, that could be the problem. I want you to go from the computer into a LAN port on the router and will therefore need to assign an IP also to the LAN side.

So for example, on the LAN side of the router you would give it the following TCP/IP information:

IP: 192.168.137.10
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.137.1 (IP of your laptop)


Then you'd want to configure DHCP for other clients connecting to the router.

I'd use the following settings:
Scope: 192.168.138.100 to 192.168.137.199
SM: 255.255.255.0
DG: 192.168.137.1
DNS: 192.168.137.1

If that DNS doesn't work, use the ones provided by your ISP (71.22.6.13
64.13.115.13)

Give that a try and see if it doesn't work properly.
