I have a work computer that I can't use at home because my Linskys router has a 1 subnet that is conflicting with the routers subnet at the office. (I have to log into their system remotely. It doesn't work at starbucks either.) Everything is fine with the internet connection, it's just this one website that they have secure that I need to be able to access. I have been told to change the ip address' subnet to a 2 somehow, but from what I understand you can change the ip address of a router but NOT the subnet of it. If it is possible to change it I'm wondering how. If it is not possible I'm wondering how you find a router that has a different subnet on the ip address besides the very popular 1. Thank you!!!

This shouldn't make any difference what your IP address is behind the router as the 192.168.x.x addresses are non-routable.

 

How are you connecting back to work?  Can you access the Internet on the work machine from home?

I can access the internet fine but to work I have to log into their VPN and then into certain webpage to upload work. The IT guy said it's keeping me out since my IP address is conflicting with theirs. I tried changing the IP address but it didn't help, they keep saying it's the subnet that's the issue. Do you you know if they even make routers with a different subnet? Thanks!

It looks like your local subnet 192.168.x.x overlaps the Corporate subnet. This can cause a problem with routing over a vpn. If their local network is on 192.168.x.x change your local network on your liksys to 10.0.0.0 or 172.16.0.0.

To help you with details we will need the model of your Linksys router. It can be done, it isn't particularly difficult, but it does take several steps in a sequence to keep from locking yourself out.

The default ip address for the LAN on that router is 192.168.1.X you can

  • Log in to the router at 192.168.1.1.
  • Enter the default user name password both are admin (I highly recommend changing these).
  • Click on the connectivity tab and select Local Network.
  • Click edit next to the Router Details tab.  
  • Change the IP address to 172.16.1.1 click Save.
  • The router will reboot.
  • You can login to the router at the new ip address 172.16.1.1 with the same user name and password as before 
  • You may need to renew your ip address to connect back to the router, You can reboot your computer, or From the command prompt type the following pressing enter after each command.
    Ipconfig /release
    
    Ipconfig /renew
    
    
  • Try to access the router again
  • Go back into the connections tab and select Local Network. Under the DHCP Server it should reflect the IP change and have a starting IP of 172.16.1.100. You can find Pictures or more detailed instructions on the Local network settings here
  • You shouldn't have an overlapping subnet anymore.
