Our ISP recently updated their hard ware to work with the Sprint network. Note: our ISP is not Sprint, but the local phone company. Our Hardware: Internet: DSL 10.0 (highest speed available) Modem: Comtrend (ISP provides) Router: Belkin N Computer: 10 yr old Dell running XP - service pac3 - wired connection Kindle Fire (first edition, no HD, etc) - wireless connection Xbox 360 - wireless connection Issues: Xbox - went from constantly bumped from Xbox Live game by losing internet connection to not being able to enter a game at all Kindle - went from occasional "network error' message during online tasks to having to restart download (multiple times) or refresh page for most any or all online tasks Computer - have to click refresh to get most any page to load after the home page What we've tried so far: I have recently cleared the cache on both the computer and Kindle. XBox's new security measures have been met. My questions: Do any or all of these issues seem to be related? Is there a piece of equipment or something we may be missing to make all of these things work? I am a networking novice. Who should I call to get these issues corrected, my ISP or a tech service? Note: if I start with the ISP and they do not find an issue I have to pay for the call.
