Lose wirless connection

Question

Brand new Inspirion 1500 - when you turn the computer on, you get connected to the wireless router.  Then after a few minutes, you lose connection.  Can't sign back on unless you reboot.    In the bottom right corner - you are told that you are connected and service is excellent.  Been on with Dell two times and it hasn't worked neither time.  Ready to send back.  Anyone else with a similar issue?

can you be more specific about the make of the router? It should be something like DI-624 (for example). There should also be a hardware revision listed on the bottom.

I only say this because several popular dlink routers have issues with intel cards that has been addressed by dlink with beta firmware (you can think of firmware as the router's internal software)

good deal ... now look under the bottom for a bar code. it will list the hardware revision. HW: C1 for example would mean the C1 revision.

there have been a lot of updates since that firmware (if it is what you're still running?). Firmware version 1.21 claims to fix issues with centrino (intel) cards. This is the newest 'production' firmware version.

Dlink has been beta testing newer firmware than this for some time. They have recently gotten it stable enough for them to release directly onto their site. While it's still in beta, you might consider upgrading to verion 3.01. If you decide not to do this or do it and have problems, I would still recommend you upgrade to at least 1.21

A firmware update will wipe your current settings. In fact, after the upgrade fully completes (say 5 minutes after you flash), I recommend holding down the reset pin on the router for 10 or so seconds -- this will ensure that all settings are reset to their default state for the new firmware. At that point, log back in and change settings (like security) as you wish.

Many dlink routers become unstable if you attempt to manually set the time or if you disable UPNP, so change these settings at your peril. Turning gaming mode 'on' will turn the SPI engine off and free up resources. Reducing transmit power to a value lower than 100% will make a lot of units stabler (probably a heat issue).

I had the same problems with a different router. Do this

Start -> Settings -> Control Panel -> System

Click the hardware tab and click device manager

Click the by Network Adapters and double click "Intel Pro 3495" then click the advanced tab

Change:
"Ad Hoc Power Management" to "Noisy Environment"
"Power Manangement" to "Full" (put the slider to the right)

That will work!
