The other day I noticed the internet was down so like usual I went and checked out the router. I noticed that there seemed to be a slight buzzing sound that went on and off so I unplugged the router, waited, then plugged it back in. The buzzing noise started again and this time it was even louder. I noticed it seemed to be coming from the router near where I plugged the power cord in. I am pretty sure this means that the router is no longer getting the correct amount of voltage but am unsure whether the problem lies in the adapter or the router itself. Does anybody know what I can do to find out? I don't want to have to go buy a new router if all i need is a new adapter.
