Broadband Connection Dropping Out

I have noticed my connection has been dropping out several times a day recently. Any ideas based on my router status?

Re: Broadband Connection Dropping Out

Hi @Hollie_B

Thanks for the reply.

The dropout was for both wired and wireless connections. It does appear to be better today.    Has something been done to it?
