Changing downstream frequency
Hi. I have a Zoom 5354 modem/router and I would like to change the downstream frequency in an attempt to get better performance and fewer disconnections. I thought it was as easy as entering the frequency and clicking the TUNE button on the Status/Connection page, but that is not the case. Is it because Channel 1 is "locked"? How would I unlock it? Thanks in advance! J
