My ISP doesn't have upstream bonding so usually my modem stays on one channel all the time, Channel 3. For some reason channel 3 gives me an upstream power level of 57dbmv. on Occasion my modem will switch to Channel 4, that channel gives me a power level of 41dbmv. I've noticed one other channel that i've been able to switch to and its channel 2, with a power reading of 38.
Anybody ever experienced this before?
