C7500 Internet Drops

Since purchasing 2 of these combos, having the same issue with current one as I did the one I returned.  Essentially, I am getting kicked offline anywhere between 1 and 5 times per hour.  ISP has sent three technicians out tot he house to troubleshoot and now there are no longer any issues from ISP's side as I have verified now on multiple calls (The Events Log is now empty for several days). From the log below from the past hour or so you will see multiples times I have been bumped in just the past hour and a half.  Please help! Also on Firmware V1.01.32 with Spectrum
