    Thnx, but I've also tried the newest drivers, both US & EU. Linksys also no help as they never returned my call. Calling it quits, will buy a different adapter.

    Same problem on installng a Linksys Wireless N adapter in a Gateway with Vista. When the adapter is plugged in the computer goes into an endless boot loop.

  • Anonymous Jul 15, 2008

    Installing the Linksys WMP300N also put my computer into an endless boot --> no post (meaning no BIOS and no error beeps) --> power off and reboot.

    I did manage to get the adapter working by doing something I DO NOT RECOMMEND: I opened my case with the computer off, popped the card loose, turned on my computer and let Windows load to the log in screen, popped the card in, and rebooted. Its not exactly recommended to install nor uninstall hardware while your computer is running, but I build computers regularly and figure I can fix anything I break. This got the card running but only until the next time I shut down the computer (reboots without full power off worked though).

    Searching various forums, no one appears to have a workable solution. I can tell you this is not a driver issue so do not waste your time downloading updated versions from Linksys. Something about the physical hardware hangs certain computers during boot possibly due to a short or errors during hardware detections (I tend to lean towards the later since I did have the card running).

    Time to go with a USB adapter... or another brand.

Disable or uninstall the Linksys software that manages and monitors the connection.

Use instead the Microsoft Windows Wireless configuration utility.

That's what I did and didn't get problem after.

I have a gateway fx7024 running windows vista and i have it located in a trailer about 150ft from my house. The WMP300N Wireless pci card is installed in my pc which has only one pci slot which use to house a dialup fax modem... Anyways when installed my pc will not start.. the fans power on and power button is lit... then when the fans hit full boar the shut off and the power light goes off for a second or two then repeats this cycle. I can put another type of wireless pci adapter in and it works fine... so not the slot. I first tried the cd then downloaded the updated vista drivers. It did once work until i shut down my pc and went to work and started the endless boot cycle. So i know it gets a great signal. i use to have the WUSB300N but it got horrible signal. Please help!!! I may try to use system restore and try all over again incase somethings hindering the machine or just give up completely...

Acer aspire is stuck in repair loop

From cold start, try F8 and if granted a choice to load as normal, choose that. If normal load succeeds, after Windows finishes loading, restart the computer. This should store a normal registry, i. e. one that does not direct you into a loop. I probably would subsequently use an sfc command but to avoid describing that I would simply suggest downloading Glary Utilities and going to the system repair menu item that will replace/repair system files. That takes a long time but then you know your system files are not corrupted. And I would reboot again, then.

But for you, here is a link that describes how to free yourself out of the endless loop if the above is of no help:

I have a Honeywell RTH6580WF Wi-Fi Thermostat that has "Cool On" or "Heat On" flashing in an endless loop. Could there be a major issue?

Pull the power red wire off the thermostat and batteries out if it has battery backup, then reinstall...much like a computer restart. If this doesn't work, then replace your thermostat.

5 short beeps followed by endless beeping after installing Windows 7

The beeps without display would indicate a problem with RAM video card, or keyboard. Try removing the RAM and putting it back in, and same with the video card. You can also try just removing the RAM and if you still get the same beeps then RAM is likely where the problem is. Same with video. Chances are there is just a bad connection and removing the components and putting them back in will fix it.

Troubleshoot motherboard

It's hard to do much testing, but I'd look for capacitors that are bulged or leaking. has way more information than you'd ever want to know about this problem

Pull everything out and reseat it, see if it works.

After that, I'd pull everything out but the motherboard, one stick of known good memory, and the video card. Also disconnect everything from the back but the keyboard and monitor. Clear CMOS using the correct jumper.
Boot up to the cannot boot prompt and let it sit for a while (15 minutes or so). Do a ctrl-alt-del and see if it reboots correctly.

Next, add in just the cdrom and boot off of it until it fails (win xp setup) Then Ctrl-alt-del and make sure it works a second time.

Now, add your hard drive and try to install. If it works, shut down, add one card at a tie back in, and test each time.
Then start adding in your usb devices, then network cabling, etc etc.

If you can, try a known good power supply.

Either you'll find the part that is causing the problem, or you'll know it's most likely your motherboard.

Cannot get out of Configurating updates: stage 3 of 3 screen

This is all I could find:

It's not only Windows Vista Service Pack 1 that isn't ready for general consumer availability. Some of the updates released on February 12, 2008, as a part of the Microsoft monthly patch cycle, have managed to effectively kill Windows Vista. Users are reporting that, following the introduction of the February 12 updates, Vista gets stuck at the finalization of the deployment of the updates displaying the message "Configuring Updates Stage 3 of 3 0% completes" and then entering
an infinite reboot loop. And there is absolutely no way out for the end users, because canceling the configuration process of the updates is a move equivalent to losing access to the operating system entirely. This will even happen in Safe Mode.

Microsoft has yet to officially respond to the issue, or to provide a resolve or at least a workaround. However, it does seem at this point that there is an issue with the deployment of the pre-requisite updates necessary for the smooth installation of Windows Vista SP1. Namely, the problem resides in the Vista installation software. The fact of the matter is that end users will have to first update the Vista installation software and only then deploy the remaining February 12 updates and only at the end Vista SP1 RTM.

If you are stuck watching the "Configuring Updates Stage 3 of 3 0% complete Do not turn off Computer" and in the endless reboot loop, then stop the cycle and boot from the Vista media. You will need to "Repair your computer," so select your Vista installation and restore it to a point before the deployment of the updates. After gaining back access to your operating system, you will have to install the service stack update, namely Update for Windows Vista (KB937287). Deploy this update before any other on your Vista, and only then install the rest. At this point in time, you should experience no more problems.

"Update 937287 is a prerequisite package that contains updates to the Windows Vista installation software. The installation software is the component that handles the installation and the removal of software updates, language packs, optional Windows features, and service packs. Update 937287 is necessary to successfully install and to remove Windows Vista SP1 on all versions of Windows Vista," Microsoft revealed.
