I have been running Windows 7 Pro (64-bit) for several months now and have loved its performance so far. It installed almost flawlessly with my laptop and immediately I noticed an increase in performance. My specs: Dell Latitude D620, 4Mb RAM, 500GB hard drive, Core 2 Duo, Intel 3945ABC wireless Late last week my wireless connection started to drop every few minutes, and now I'm to a point where I can't even use the internet unless I'm hard wired. This problem happens everywhere (coffee shops, at home, at work, etc) and I've tried not only the driver that automatically installed with 7, but a newer version from Dell and yet a newer version directly from the Intel site. Each time I've completely deleted the adapter from Device Manager, then reinstalled it using the three drivers mentioned above. I'm not sure where to go from here, because basically I can't use my laptop unless I'm hard wired to a router. Again, this isn't related to any particular router, and I've tried 3 different drivers. Help! In advance, thanks. Sean Conley

Anything in the Event Viewer that may provide a clue? Click Start=>type event in the search box=>select event viewer from the programs results. Let it refresh, then click the + next to critical and error. Find anything? This is usually related to the adapter drivers. As you have tried those, I would recommend using the latest Intel version to be sure. The 13.3.0.137 appears to be the latest version. Let Windows control the connection. You can uninstall the ProSet software after installing the package. http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=19328&lang=eng You may want check your security software settings or confirm that you have the latest version. Finally, if all of those are ok, check the physical connection of the card and antenna leads. Also, check the properties of the 3945 in device manager and check the power settings. Uncheck any power saving options for the card and check the options in the advanced settings of your power plan.

Thanks for your response Nano! As of this morning I've restored an image I took right before the Oct 27 updates released by Microsoft. The more I read online about that series of updates, and the problems people are experiencing since then, the more I decided the path to take was to restore the image. Son of a gun if it doesn't seem to have resolved my wireless problem. I've only been back up for 30 minutes, but so far not a single dropped signal as I closely watch the wireless meter I have on my desktop (which previously was changing yellow, then red as the signal bounced). I've not made a single other change except to restore that image, so in my opinion there is definitely something up with that series of updates. Now in response to your suggestions above....I was in fact running the version of the wireless drivers you suggested, and ironically I'm using Microsoft Security Essentials, though again I made no changes to either prior to the wireless problem. So those really can't be the issue. I did not, and still have not, checked the wireless antenna connection, so unless it tightened itself back up that also was not the issue. In regards to the Event Viewer, I actually had been going through that log and found several error messages related to my wireless (Source-BROWSER and EventID=8033) that were described on another blog I read, and that blog also believed that updates caused the problem. Again, since restoring this image from prior to the Oct 27 updates, I don't find those entries in my log at all. Now here will be the real test. I'm going to apply those updates again to see if I start experiecing the problem. If so, then my suspicion about the updates may very well be true. I'll post again after I reapply...... And again, thanks for your response!

Interesting, apply the updates one at time to try and narrow it down. Then we can look into the KB #.

Here's a little update. I reimaged my machine back on the 3rd and had no problems in the following days...everything seemed to be back to normal. However, today I've noticed it dropping out a couple times, both at home and at a coffee shop that I frequent. I've since reapplied all the updates, but have left the original driver (by Microsoft, dated 03/26/2009) that installs with Windows 7 in tact. So I've made no changes to the driver, but allowed all updates to be installed, and as I sit here I can see it bounce around a bit. It has only fallen into the yellow once though, and has never completely dropped out. I hate to say it, but this is reminiscent of the way it happened in the beginning. Updates were installed on 10/27/2010, and I didn't notice any problems until about 11/01/2010. Will update again later....

I don't believe drivers are the issue. I am starting to suspect the card, a power issue, or just general interference. Does this happen only on battery power? Do you have the 9-cell battery? The original Dell software disables the LAN ethernet network adapter when on wireless. (Quickset) Dell doesn't have that software for Windows 7. I had an M90 (same chipset), on which I replaced the 3945 with a 4965AGN for N capability, but noticed improvement in the G signal. It's a pain to swap the cards on the D620. http://support.dell.com/support/edocs/systems/latd620/en/SM/minicard.htm#wp1084976 Perhaps, try to adjust the adapter settings for Wireless G only. It may be switching\seeking on multiple broadcast access points. Also, if you allow the Intel Proset software to be installed, you can use it to view the connection statistics. This may help determine if it is interference from surrounding signals, power, dropped packets. etc. Channel 11 is usually better than channel 01, but you can't control that on public access points. http://www.intel.com/support/wireless/wlan/sb/CS-031653.htm Watch the video.

I guess I don't think it's a hardware issue primarily because the image that I restored (from prior to the 27 Oct patches) fixed things immediately. Today now, I don't notice the problem at all, at least not so far. That suggests to me that last night might very well have been interference. I guess I'm just going to keep an eye on it to see if anything else starts to "slip," but it seems to be working for now and at least I know that I can always fall back to my 23 Oct image to get it working again. I guess the lesson I'm learning is make sure you take frequent images so if you need to undo drivers/update/etc you can always fall back to a prior point in time. Thanks for your assistance and suggestions!

Restore points work for that purpose also as only the system files are restored. Also, in device manager, properties for a device, you can roll back to a previous driver version for the selected device. Good Luck and I hope all will work well. Post here again for this or any other issues.

I'm having the same issue. Fresh full clean install of Windows 7 64 Bit Pro. WIRED connection Via CAT 6 Cable to Lynksis 4 Port Router & Modem. 3 other Nods running XP on the Router work perfect. Windows 7 drops internet connection alerting with yellow triangle in corner window. No idea. I have installed all updates, patches, drivers, etc etc etc. Nothing works. Windows 7 is the ONLY one having this issue. All my Windows XP Pro Nods work perfect. They are all on the same Router and Modem as 7. Any ideas? This is nuts.
