So I live in MA in an apartment complex, and I have Comcast Xfinity, and it sucks. The internet speeds are half what they should be, granted I use wifi for desktop not ethernet, but the modem/router is right next to my desktop. I have a signal amplifier for my cable boxes, but they freeze constantly when browsing on demand. I am having the technician call me back tomorrow to figure it out. I am sure it is outdated wiring somewhere within the complex, because all of the wiring in my apartment is brand new as of june this year.
