Dropping Signal

I currently only get Good Signal within my house and the last two weeks it keeps dropping to week and when it does I am unable to do anything.  I WFH and this is becoming a huge issues.  I had to use my Verizon MIFI last week as my back up but I am starting to look for other options because this is how I earn a living.  I used to have AT&T and switched because their speed was HORRIBLE and data was limited but I am over not being able to connect devices or work from home.  Am I the only one having this issue?
