We have three ADSL Wifi Routers which are connected to my ISPs, these are wifi access points for the various computers that we use at office.
Devices used: http://www.dlink.co.in/products/?pid=451 and a similar wifi router/adsl model device from DLink
I am trying to see if users of each of these routers be combined into one single Local Network where file sharing, usage of the same Radius server for Enterprise Authentication, sharing of web servers etc. can be done.
I have tried to connect two of them first using the following technique and had no positive results. I turned the DHCP off on one of the routers and assigned it 192.168.1.2 as the IP address, the other router which assigns DHCP based IP addresses has been given a range starting 192.168.1.3. After configuring the above, I have connected these two routers (with IP 192.168.1.1 and 192.168.1.2) using a regular LAN Cable.
After the above setup each computer connected to these routers are able to access internet, using the appropriate gateway IP addresses, however each of these computers are not able to identify the other over the Network. I thought since now all the devices are connected and share an IP range and are on the same subnet Mask (255.255.255.0) they would all the visible to each other, but my network skills in this are are very limited and I could be talking completely unworkable and illogical things here.
The reason for this whole division of connections is because I am in a location where the connectivity speed per broadband is only good up to 8 Mbps and we need more than that leaving multiple connections as the only option, any other innovative way to achieve what I am trying to do are welcome.
Thank you for reading and your time, let me know if I can add more information or make the question clearer by any means.
