So my friend is paying for gigabit internet through cox, they have a technicolor-cgm4141 which claims to be a gigabit Modem/Router however they are only getting 100mbps through ethernet and about 300mbps over wifi on 5 GHz from about 10 feet away. The ethernet cord may only be able to push 100mbps not sure If its a cat5 or not (Most likely, is she bought it from best buy) however i feel like they should at least be getting better wifi speeds though. The Modem/Router was recommended and installed by cox for gigabit so not sure where the problem lies. Any info would help, Thank you!
