Hi, I'm on the Unlimited Broadband and Huawei e5577 bill pay plan, I was told I'd get super fast unlimited broadband. I can't even watch a 720p video for more than 2 minutes without it buffering. Why is that, and how can I fix it? And please don't tell me ring your tech support team, surely you guys on this website will be able to sort this out? And I have reset the modem twice, that is not the solution. Thanks!
