[ubuntu] Intel® Pentium(R) CPU B970 @ 2.30GHz × 2 slow internet

Since upgrading to Ubuntu 16.04 my inteet coection speeds seem to be very slow at times. I never encountered this problem with 14.04. I am ruing 16,04, 64 bit with 8 Gb ram. This is my wireless tar.gz which I have looked at, but might as well have tried to split the atom. I am hoping that someone can tell me where my problem lies. Oh, I'm using chrome as my browser, but firefox encounters the same problems as in many forums are very slow to load or refresh pages.
