I'm not familiar with the 9460 itself, but the symptoms you describe are consistent with a grounding/earthing issue. When electrostatic charges (ionization) are not shunted to ground properly, they tend to accumulate inside the modem. Ones get changed to zeros and vice versa. The modem gets slower and slower until the point it simply locks up. Restarting and/or power cycling resets all the ones and zeros to default, and the modem returns to normal operation - only to repeat the cycle as it absorbs more "static"
When this is determined to the be cause, the fix is inspect/repair/replace/install appropriate bonding/grounding on both the ODU and the cable path. On the ODU the TRIA should be bonded to the reflector bracket, which in turn should be earthed at a grounding electrode common to both the modem and the cable. The cable sheathing should be grounded at this same common point. The modem power adapter should be connected to an AC source which too is ultimately grounded at this common.
The goal is twofold; (a) shunt electrostatic charges to ground, and (b) equalize electrical ground potential between among the three components; ODU, cable path, modem.
