l stil have the access to the network even after l asked them to freeze it. They were demanding that l pay for the 3 months l was not paying them, l demanded that the pay me back all the money l was paying for over 4months whilst there networking was not working. So we ended up agreeing that they will forget about the money they think l failed to pay, and they will freeze my account until when lm ready to use them again!
EVDO or .1x?
There is a lot of confusion l think is going on even to some extend propelled by PowerTel themselves. One tells you that they use EVDO and another tell you that they use use 1x, but do we people ask what is EVDO or 1x?
Even more strange is that about a week ago my dongle started to refuse to connect, l then discovered that they PowerTel has flipped from PAP authentication to CHAP??? l changed the settings to match and l was back in bussiness again but not for long. l asked one of my friends to test the dongle she use, surely it was connecting through PAP, mine through CHAP???
Anywhere, that got me to conclude that PowerTel have all sorts of authentication servers all over the place from different vendors and methods. This will tend to affect us paying customers. This will lead to issues of customers sometimes failing totally to connect or when they get connected, they dont go very far as to get internet services.
Then, what is .1x?
lt is the ISO standard for NAC(Network Access Control). In summary to you and me simply means that when you or l connect my dongle, PowerTel have to verify that lm suppose to be connected to there network. Once this is verified, PowerTel now decides what service lm suppose to get, is it going to be unlimited access or pay per minute etc. When this is all done, your dongle gets IP address, default gateway and DNS servers address to access the internet, then you can now almost happily get internet. ln nutshell, .1x verifies that you are a customer of PowerTel and you have paid them money to connect.
Then EVDO kicks in. EVDO is the actual method which is going to carry traffic wireless between your PC and internet. When you or l is downloading our movies, it is evdo which is active doing all the donkey work.
So .1x starts the whole process of authentication, then it hands over to EVDO once it is happy that customer is properly authenticated. But in the real world of PowerTel, this is not happening, they have all sorts of things going on some which works against each other, then it is the customer whole suffers mostly.
Unless if someone have a better ideal, thus is my personal observation.
