I looked into it and found folk reporting to roll back the firmware version. Fixed mine and later we found ourselves doing this to other routers.
It's not settings from what I can tell.
This is more prevalent since I got a new Samsung Note 10.9 tablet. I do not know if it is due to the number of devices I connect or not. I use a wired desktop, wireless Directv, wireless laptop, wireless PS3, wireless Wii, 2 Phones and now my tablet. Rarely are all on at once, but I typically run into a problem when I turn on my PS3, and my new phone typically has trouble connecting when I attempt to connect with it.
My Router is a good one by Linksys, WRT330N gigabit gaming router with wireless N.
This issue has been alot worse since I got my new tablet, but the PS3 has always given me problems.
Is it in the settings, or do I need to get a new router?
