x-post from AskReddit Wireless Router Question

So I've been having internet problems the last couple of days. My internet provider has said the problems are not on their side of things, and instead are most likely related to my wireless router. I will be on the internet just fine, but after say 45 minutes my internet will cut out. If I go unplug both the modem and router, wait a minute, plug them back in, the internet starts up fine again. Anybody else experience this? Any solutions?

If it helps, I never experienced these problems until I had to undo my wireless security. I had a secure network, but then for some reason mac computers couldn't connect, even though they had the correct password. I don't know if the security is related to this problem.

Thanks a million for any help you can provide. I tried looking for a computer help subreddit but it appeared empty.

Additional Info: While looking other places online, one forum suggested not having your router plugged into a surge protector. Mine is, is that really a problem?
