Hey guise, 5 days ago, my modem stopped working for some reason. I called my ISP provider and a technician came and fixed the issue. But for some reason my router became really slow. My speed before my modem stopped working were around 5Mb/s through my router and modem. Now my router only gives me around .3 - .5 if I'm lucky, wired and wireless. My modem is still giving me full speed, 5 Mb/s. My question is, has this technician guy made something so that my router doesn't give me full speed? . Is there something I can do to fix it??
