I'm considering getting rid of my landline and purchasing a MJ. I owned one a few years back but my DSL connection is so bad that I gave it away. I'm likely going to cable internet where the download speed will be up to 3 Mbps and the upload speed "up to" 256 Kbps. There are often up to 5 of us on our wireless laptops at a given time in our house. I know the minimum requirement for upload speed is 125 for MJ. Do you think it will work OK if I'm getting in the 256 range?
