What is wrong with my internet?

[BigDave]

So i got this new router thinking it would solve my problems. The router i believe works great and allows more devices on my network.

However, my internet is constantly cutting out. As my laptop is in front of me much of the time, i am able to see it cut out. I click the troubleshoot button and after about 20-30 seconds it comes back. this happens a few times a day.

Could this be a problem with the modem (are there better ones to handle more devices) or is this a problem with the internet service (att)?

Yes i have already reset everything and attached a booster to the network also to ensure its not a signal problem
