Is your office network a Domain Server or just a workgroup?
If a workgroup you can make sure both your office & home workgroup are the same name.
If your TCP/IP Properties are set to obtain an IP address automatically, each time you reboot in your office or at home it should connect to your Linksys Router automatically.
I have a centrino enabled notebook which I use on both my home and office networks. All of a sudden, without making any intentional configuration changes, I can't get on the office network.
I can ping the Linksys wireless router but I can't access it in my browser. I can't even access the workgroup to see other resources. Net view shows nothing.
I tried setting an alternate configuration in TCP/IP properties to no avail.
