Hi there, im looking for some advice on how to overcome a problem i have with my home networking.


Currently i have one network on a Linksys WAG160N ADSL router which is connected to BtBroadband through a normal phone line. This has 2 computers + a laptop running on it.

I also have another network (going to be setup) on an O2 Wireless box plugged into a secondary phone line with its own seperate broadband.

The aim of this is i want to be able to still transfer files over between all the computers in the home, but i still need to keep the broadband connections seperate (The BT one is for the general web browsing and downloading, the O2 one is being used ont he gaming computers to keep the pings down etc).

So overview,
2 Computers + Laptop > Linksys WAG160N Bt Broadband
&
4 Computers > O2 Wireless Box II O2 Broadband


Whats the best way of connecting the two networks together?

Any suggestions welcome.
 
I'm assuming both networks are NAT behind the routers.

Biggest problem you will have is if you try and run a DHCP server on that network, or god forbid two of them, so turn off DHCP on the routers.

Configure the PC's manually, with ip addresses and default gateways and just make sure they are in the same subnets and IP ranges and set the gateway for the first two to be the Linksys and the gateway for the second two to be the O2 router.

They should still be able to talk to each other unless I am completely off my trolley :)
 
Ok yeah i get that, how do i actually physically connect the two networks together though?

I mean do i somehow connect the two routers together also? I dont believe either has a WAN port, and the computers are connected to them via network cables and wireless.
 
Hamachi, I suppose the only limiter is that it'll use your internet connections to do the file transfers so may be slow.
 
Hehe no i cant use the internet connection to transfer files, thats impossible :o

Maybe the answer is for me to just get an extra network card in my pc's and connect them to both networks?

Maybe the most simple trouble free option?
 
Yeah i do have one but theres other reasons i need it networked. I dont want to have to allways plugin a HDD every time i wanna transfer something.
 
This is actually a lot simpler than people are making out.

1) Assign both routers a LAN ip on the same subnet

e.g.
Linksys - 192.168.1.253/255.255.255.0
Speedtouch - 192.168.1.254/255.255.255.0

2) Turn off DHCP on the O2 router because we are going to assign its client, the gaming pc, an address manually.
3) Put all the machines on the same LAN (broadcast domain) by physically patching a cable from one of the LAN ports on the linksys to a lan port on the speedtouch.
4) connect your gaming PC to any of the ports, doesnt matter if is on the linksys, speedtouch or even wireless as you have bridged them in step 3.
5) Assign the gaming pc a static ip config as follows:

IP 192.168.1.101
subnet mask 255.255.255.0
gateway 192.168.1.254
dns1: 192.168.1.245
dns2: none

done!
