Want plug my win7's rj45 cable into different router and print

What makes a win7 computer blind to a router ?

I have a www connected win7 it uses a TC LINK ROUTER. It cant find my linksys router on IP address 192.168.1.102 .

I would like to unplug from the TC link and plug into the linksys and print at times. But the www win7 computer is blind to the linksys router and the network printer that is connected to it.

I suppose I could change the Ip addresses on the linksys router and printer to be on the 169.254.2xx.xx
and try to assign them a new number with very last IP number to be different.

Or Maybe someone can shed light on my mind as to what I could do to my windows 7 that uses the TC-Link router (169.254) so It will also see the printer and linksys router.



To explain these pictures- The picture on the right is what happens when I unplug the www win7 machine from its router and plug it into the lynksys router.... something makes it so it wont see the router or the printer. The picture on the left is a machine that will connect to the lynksys router probably because I have never connected it to the TC link router and surfed the web with it.

What happens to a win 7 s configuration that makes it so it wont see a different router. ?

I have read about IP addresses and networking a lot but its all just gobbly gook to me.

Hi Don

The IP address you quote for the Internet connected PC 169.254.2xx.xx is actually a default used when the system cannot decipher the actual IP address in use, this is basically a place holder which will automatically be changed when you set-up the PC and router to talk to each other.

You currently have two routers, is there a practical reason for this? or is it just a result of the history of your network?

Connecting a single Router, all the PCs and the printer to the same Subnet, (a subnet is a set of IP addresses in a specific format eg 192.168.1.0 to 192.168.1.255), will give you full access between the PCs and the internet and Printer at the same time.

If you wish to specifically isolate the Graphics systems from the internet then this can be done using facilities in the routers to set up the routing allowed (you would basically connect all the PCs to the one router and the other router to the internet and the first router and only allow a specific system to actually reach the internet, this is a much more complex setup of course

I will ask this question differently

192.168.1.102 is on a different network to 192.168.0.102 the ip you doesnt give the details of the dns were are you getting these ip from 2 different networks the .0 is one and .1 is another to have 2 routers the second one should have dhcp turned off and an ip in the same range as the main one

Just to clarify the way that "Dotted Decimal" notation works ...

the first two numbers show that this network is in a range that is used for internal, (non internet) addresses - The third number is a set of 256 addresses, and the fourth group is the actual address of the device.

To have all devices "see" each other the first three number groups have to be the same and each device needs a unique number in the fourth group.

This is much simpler to do if you only use one router but should be possible with two

the normal way to assign the addresses on a home network is to allow the router to assign them automatically to all attached devices. (192.168.0.1-192.168.0.255)

without understanding the way that your TC-link, (TP-Link?), Router connects to the internet I cannot be certain how to get everything to work together - if however you set up all devices to obtain their addresses automatically set this router to assign addresses in the 192.168.0.1-20 range and the other router to assign addresses in the Range 192.168.0.21-255 this should work as long as you connect the two routers together by ethernet cable or if you move the cables between the routers manually as you need to
