I got Shaw service recently, TV and phone are ok but Internet WIFI is awful. I have complained several times and after couples visits the tech guys has been trying to solve the issue without any success. I've changed the channels but no improvements. The modem-router (Cisco DPC 3825) was moved from the basement to upstairs but the problem continuous. The modem-router has been changed 3 times by the technicians (same brand and model) and the issue continue. Doing the speed test the speed moves from 0 to 19 Mbps from almost simultaneous tries.
Have somebody changed the modem-router for another brand? or solve the issue definitely, how?
