Glad I found this thread. I've been wrestling with the D830 wifi radio dropping for a while - as a matter of fact, it just happened again, but I'm plugged into the wired network. Also - does this fix the hardware switch on the left side of the machine? I can use that to turn Bluetooth on/off, but it doesn't seem to control wifi(?)

I found some documentation that suggested taking out the internal wifi card and re-inserting it, but after trying that, the radio still drops occasionally and restarting the machine seems to be the only way to fix it. The process for removing and reseating the wifi card is pretty tricky, btw, and since it hasn't improved performance in this case it's probably not worth the risk and I won't post the instructions here.
The hardwire switch on the side appears to be working correctly. When the wifi radio is on and functioning, I can turn it off and back on with the switch and after the wifi radio drops unexpectedly, the hardwire switch will still turn Bluetooth on/off.
Anyone else had any luck with this issue?
I have some questions on this issue. If anyone has this problem with the D830 Wifi this would help to troubleshoot the problem.
What Operating System (XP, Vista, etc)?
What BIOS are you running on the D830?
Which wireless card is inside the laptop, is it an Intel or Dell brand? Are you using the current drivers for whichever card you are using? If it's an Intel card have you tried drivers directly from Intel's website?
What brand/speed of wireless router are you connecting to?
I have the same problem (many Wi-Fi disconnections, low-performances Wi-Fi) for many months.
Here are my details (latest version from DELL's website):
I found a quite similar problem described there : <http://www.mydigitallife.info/2007/09/15/intel-pro-wireless-3945abg-wifi-radio-adapter-shut-off-randomly/>.
It is very frustating to have a wireless laptop which works well only when wired...
Do you have a Linksys router? I found this in the release notes of the latest Intel driver version 12.4.
After the association flow completes, the adapter stays awake (as in CAM mode) for 10 seconds, and then acts according to the PowerIndex (PI) regkey. PI should not be change during this period. The association timeout is 10 seconds. Using the Linksys access point, association occurs every 60 seconds, resulting in deauthentication and disconnection from the Linksys access point.
Thanks for the answer, but I have this problem with the NETGEAR WNR2000 router (802.11 N), the D-Link DSL-G684T modem-router (802.11 G), and other (modem/)routers.
The problem does not seem to appear with the (Vodafone / SFR / N9uf Tel9com) N9uf Box 4 (802.11 G, Broadcom BCM94318 chip).
Any other idea?
I have exatly the same problem. Seems if i use this two command the wireless start again work for 5/10 min. After that I have to do the same...
Any other idea???
