Random "No Internet access" problem on WiFi laptop

Hey guys, I'm experiencing a frustrating issue with my wireless connection on my W7 laptop and was hoping for some troubleshooting tips.

First off, here are the relevant specs:

- HP Pavilion dv9000 laptop computer (Windows 7 Ultimate)
- Intel Wireless WiFi Link 4965AGN (Network adapter)
- Speedstream 6520 (Wireless DSL router)

Recently, I've been experiencing a problem where my wireless Internet connection randomly goes from "Internet access" status to "No Internet access" status. Sometimes it also goes to "Limited access". The (!) yellow exclamation point shows up on the wireless icon in the right-hand taskbar corner.

I can fix this temporarily by turning the wireless switch off and back on again (I have a physical switch on my laptop), which brings back the Internet access. But after about 15 minutes give or take, the connection fails again. It is an extremely frustrating occurrence that now happens every 15 minutes without fail.

Things that might be causing this:
- Recently changed my SSID
- Recently disabled SSID broadcast to prevent neighbors from seeking out my connection

Things I've done to try fixing the problem that have not worked:
- Changing SSID again
- Enabling SSID broadcast
- Changing the router's channel (I've tried channels 11, 10, 6, 2)
- Checking the power setting on my network adapter to make sure it wasn't shutting off on low power


Any help? Thanks a lot in advance, guys. By the way, I also have an Ethernet-linked desktop on the same router, and this problem is not occurring on it.

N series can often do some pretty strange things. One thing I see happen is the card will latch at 300Mbps but it is meant for 150Mbps so obviously it won't see the router. Look to see what speed it is reporting it has latched at. The other is if you don't have IPV6 addresses working then disable the IPV6 component of your nic in the Control Panel settings for the Network Card.

Thanks for the tips, but unfortunately that didn't seem to solve the problem.

One thing I wanted to add that I just noticed was that it seems this issue happens when I'm actively browsing through the Internet.... but doesn't happen when activity is very limited.

For example, I left the laptop alone for over 1 hour and it stayed connected, but within minutes of browsing it failed again. Could this have something to do with the Internet activity itself tripping up the connection?

Here's a screencap of the situation:

Look and see if you are allowing the network card, the one on the laptop, to go to sleep, there are several issues within Windows 7 that either occur when going to sleep, while sleeping or while awakening, these are basically on different PC's/laptops but do occur. If you are allowing the NIC to sleep or hibernate turn that option off, in fact I don't allow any of my PC's/laptops to sleep/hibernate when on power and have had very little in the way of issues.
