Mine does a similar thing. Not necessarily every day but a good 5 out of 7 days a week I lose the Internet for 1 to 30 minutes. I also have a very 'sluggish' connection off and on. My speed tests vary. I do not use WIFI and it is not activated. This has been going on for years, on different computers, different modems and at different addresses. I've moved a few times over the past few years, gotten new modems, new computer and there's more than one computer in my home. So this can only be a Shaw problem. And, by the way, I've been working with computer since 1970 so it's not like I don't know what I'm doing.
