MG7550 drops frequently

Unlike my old unit, this unit frequently drops connections. I have always been on Spectrum with no issues.  I replaced my old unit with this one to gain additional wifi range.  All too frequently I go to sign on only to find I have to reset my unit.  

In addition, my spouse is frequently interrupted on her I-pad.

This seems to be a frequent issue when I research it on the web.

I need to repair or replace it.  Thoughts?

Thanks
