This is my experience dealing with the Telmex/slow speed Internet here. I live in Mazatlan, but rented a house in Villa Nova in Ajijic for a month. The speed at this house is 6 Mbps download and .6 Mbps upload. I already knew that the speeds in Ajijic were slow, but I called the Infinitum trouble report number and talked to a tech there. She looked at the line and said she saw no problems and there was nothing she could do from where she was to improve the speed, but she gave me a trouble ticket number and said a tech would come by and check the line. A tech came by a couple of days later. He checked the line coming in to the house and said the maximum coming in to the house was 7 Mbps and it is normal for me to see 6 Mbps, using the “speedtest.net” Web site that shows how much a person is getting with their computer or other device. He said I was lucky to get 6 Mbps. He said across the road at another subdivision, and in other parts of Ajijic, the maximum download speed is 2 or 3 Mbps. And I believe him. I talked to a woman in the Ajijic Telmex office. She lives not far from this house and she said she does only get 2 or 3 Mbps download. For the last 3 weeks I had thought about buying a new modem from Mercado Libre, just to give it a try at this house to see if it made any improvement in speed. I finally did it about a week ago. The modem that was being used at this house was a Huawei HG532e from 2012. It was and still is a good modem. The modem I got from Mercado Libre is a Huawei HG659. It was manufactured in April of this year. It is the latest in technology. It is a 2 band modem transmitting at 2.4 and 5 GHz. And incredibly, I paid 240 pesos for it. That is about $13 or $14 US dollars and for that price it was shipped to me by the seller and got here within 2 days by FEDEX. It did not improve the down speed, but did improve the up speed from .6 Mbps to around 1 Mbps. I might have been able to call the Infinitum techs in Mexico City and ask them if there were any options they could change remotely from there to try to improve my speed, but being as this is not my house I did not want to do that. Modems like this were designed to be used with fiber optic facilities, but being as they are the latest in technology, being 5 or 6 years newer than the old modems, they do sometimes make an improvement in speed. I will of course take this new modem back to Mazatlan. I have an HG 658 modem there and I get down speed of between 35 to 40 Mbps. I do not have fiber optic cable in to my house, but there is apparently fiber optic cable somewhere between my house and the central office. So I will use this wonderful HG659 in Mazatlan and will have the HG658 as a backup.
