Constant Internet Dropping every summer and getting worse

Every summer when it starts getting warm out, my internet gets to the point where its almost un-usable with the constant drops.  I have called in many times and customer service just says to reboot modem, 10 mins later same issue.  Have had many techs come out and each one has a different idea and the issue remains and gets worse over the summer and years.  Any Ideas? Replaced Modem, All wires are tight, have rebooted modem so many times I can't count.  I have many pages of the same errors over and over again.
