I haven't really tried anything until now to fix the problem. The map is as follows:
The 5180C HP printer is wired into the Lynksys Router.
The desktop HP (Windows 7) is wired into the Lynksys Router.
The 3100 HP printer is wireless.
Two laptops (one using XP, one using Windows 7) are both wireless.
We have these computers and printers networked on a secure system. However, we have another problem in accessing files from one computer/laptop to another. We used to be able to do this easily, but all of a sudden, it's not working. We've decided to solve one problem at a time though.
All computers, both laptops and desktop, lose the IP address to both printers. There is no warning when this happens. It doesn't always happen at the same time for all the computers or printers. We find the IP address has changed when we go to print and nothing happens. We know how to change the ports, but it'd be nice not to have to.
Today I did the following per suggestion at answers.yahoo.com:
Went to Network Connections
Wireless Connectin Status
Copied info regarding current IP Address, Subnet Mask, Gateway, and DNS Addresses.
Set Fixed IP Address using copied info.
Do I need to do something with the port info on the printers now, or is it fixed? I don't want to do this on all three computers until I know it was the right thing to do.
Any and all feedback is much appreciated.
