We had the same problem with our Telcel modem this week that we've had for around 6 months. Took it to Telcel and found out we had used the allotted 150,000 Mbps that you get per month. Have no idea really why that happened, but we had may have downloaded more this month. So, they let you buy 100 pesos of more Mbps at a time, but that's all. So, if you use that up, then you can go buy another 100 pesos until a new month rolls around. The speed is throttled way down so nothing works until you put more money on it! Give me a break! Hurry up Ilox.
