Fixing Connectivity Issues

by whizzer0120 - 2/26/13 9:44 PM

Hello,

This is kind of a complicated setup, but the answer has to be pretty simple. Here it is:

Wireless Router: Linksys EA4500
Printer: Brother MFC 7840W

The above devices are in a home office in a loft space. There has always been a problem with connectivity, but the issue is that the printer's functions will not work.

Communication between the printer and the router has been problematic, specifically getting the IP address to match and the signal to be consistent. I found someone to fix that issue for my boss a few times, but he wants me to try and do it myself to avoid paying that contractor's fee. I am not a trained IT person; everything i have learned has been through trial and error.

The router above has been installed yesterday and I was trying to get the connection between the two. Until I got with Brother tech support, the printer kept giving a "Connection NG" error message with the IP address always at 0.0.0.0.

After the session with Brother tech support, the printer says it's connected, with an IP address matching the router, but only will print from the wireless computer that pinged the printer during that session. Even then, there is no access to scanning, giving the only option to scan to FTP.

The router itself now recognizes the printer, but other computers attached to the network will not print and any attempts to scan will return a message saying "Not Registered."

I think that the solution comes to adjusting the wireless settings on the router, but I am not sure which to adjust.

Here is what I have tried so far:
-The router is a double band router. I have disabled the
5GHz option, leaving only the 2.5 GHz

-I have tried to adjust the channels to match what
comes on in the Brother printer, which is receiving on
Channel 3 and an operating on Channel 1.

-I don't remember the name of the function, but the choices were Auto or 20 MHz. I can definitely clarify this point.

The tech support person mentioned connecting connecting the printer to the router with a ethernet cable. That wouldn't work because the distance is too great. However, a 20 ft. ethernet cable can reach the range amplifier. My only concern is that the name for amplifier will not allow users to use all of the capabilities on the printer.

A potential solution could is for the computer that is wired to the router to ping the printer, or a potential adjustment in the router in the DHCP numbers. Other than that, it may come down to pinging and at least getting the print function to work.

Excuse the long summary, but if anyone has any suggestions, that would be helpful.
