Dropping Internet

[pamtech]

Our new HP Dm4 (Windows 7) frequently drops its internet connection but stays connected to the wireless network. Access to the internet will become slow and then finally disappear. The connection can only be revived by turning the laptop wifi off and then on, or rebooting the modem and router.
The internet does not drop when wired to an Ethernet port on the router.
I am using a Belkin N+ router (F5D8235-4 v2000) with the latest firmware (3/11). My 3-year old Vista machine and iPad have no problem at all. I did have a similar problem with the iPad when I bought it earlier this year, but the problem disappeared when Belkin released new firmware.
Hoping someone might have a suggestion – thanks!

Try changing the channel on your router. There might be some other device talking on the same channel.

Thanks for your reply jat421. I'll give that a try, though I'm not sure that's the issue. My other laptop and iPad work fine.

Make sure you have the latest wireless driver--from HP's web site if the adapter is integrated.

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector. (If you are not fond of making random changes take a look at this output before deciding on a channel change.)

And show for when you have internet access via wireless and for when it has been lost ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following command:

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
