I connected my new Hub 3 last night, following all the instructions, to find that it wasn't working, I called 150 and whilst on hold it started working as I was able to access the internet. However, this lasted for about 30 minutes then the wi-fi light started flashing green as did the base LED light. I unplugged both hub re started my mac which seemed to cure it. However when I shut down my mac within 10 mins the internet had disappeared again and the same thing happened. I did the same thing this morning turning off the hub, only for the connection to drop once i had shut down the mac. I have had a superhub for a number of years and never encountered any problems whatsoever, so am rather perplexed as to why this is happening? Has anyone encountered anything similar?
