We have the Superhub up to 70mb. In the last few weeks the router has been constantly dropping connection 3/4 times every hour, taking an age to load pages on phones, tablets and laptops & making online gaming absolutely impossible. I've ran speed tests and the results come back as good as normal, we've rang the support line and had resets done many times but these simply aren't helping. The lag stops for around 15 minutes after each reset but then starts again soon after.
We've tested one device at a time and they all still seem affected and as I said the main use, gaming, has become impossible which is appalling when we pay so much money for the speed mentioned.
