Problem with wireless adapter or access point.

Does Kaspersky update at various times of the day? You might take a look in the task manager when this happens, just to see which program is using the most memory and CPU.

Thanks for updating model info. Here are the HP pages. I tend to start with the manufacture's pages to see if there's anything there - most of the time it's fruitless, but somethimes I learn something.

Wireless Networking HP G61-408CA Notebook PC

Troubleshoot a Lost Internet or E-mail Connection on a Wireless Network (Windows 7) HP G61-408CA Notebook PC

Have you tried a wired connection - does that exhibit the same issue?

Sometimes Bluetooth gets in the way - do you use Bluetooth connectivity (I haven't looked ot see if your machine has BT).

Run Windows Update (WU) manualy and see if there are any optional components offered. Sometimes peopel miss hardware updates provided by WU if they only get automatic updates.

Intermittent issues are difficult to resolve, so we'll just have to run down the list to eliminate the usual suspects.

I'm looking around for information on your cable modem, but all I find are press releases similar to what you posted.
Reaching New Heights - Rogers Launches its Most Extensive Wi-Fi Yet | Hitron Technologies Americas Inc.

This might take a while and I'm on Internet life support. If I don't post, it's probably because I can't get to the Internet.

Have you called Rogers? They can do some testing from their side and if necessary come on-site to diagnose hte connection using your machine.
