Hi this is the problem i buy a router because where i live the wifi signal arrieves bad and the connection of 30 mg come to 6 or 7, i buy this modem and it works the first month i get 25-26 mgs but then one day i start to receive 2 mgs i think that was because some one star to download something but the problem continue for a week so i decieded to restart the router and doesn't work, so i go to my principal modem and connect in him and he registered the 30 mgs, so i call technichal support and they tell me that i should go for a new one. I already go for this and when i bring it to home i connect this time the router by LAN and that works i receive again 30 mgs to 26 but yesterday again it happens like 3 days later to i bring the new one to home start to give me the 2 megas, so i go again to the main modem and its the same problem i don't know what i can do for solve this its the modem problem or what thanks for your help.
