Internet Provider Help

[BRL1]

I need some recommendations for Internet Providers. The only hard requirement I need to meet is a minimum of 3Mps upload speed. My daughter in law is working from home and that is the company requirements. The provider I have now is only getting me 1.6 Mps upload. She does alright with it but the last couple of days it has dropped to 1.3 and the telemarketing system she is using does not work. To keep it where she can work we have to turn off all other phones, tablets, Netflix for the day while she is there.

So I need to find something that everyone can use at the same time. Good reliability, fair price, decent customer service would be a bonus and in the next couple days would be a big help.

Thanks for any help.
