Question about SMC EZ Connect g SMCWPCI-G (SMCWPCIG) 802.11g/b Wireless Adapter

Win XO Pro displays MSG: "IRQL_NOT LESS OR EQUAL" on blue screen. Sounds like a hardware compatibility problem with SMCWPCI-G2 wireless card adapater. Any hints on how to solve this?

    ButtFuz, Tx for your input. It helps me narrow down the problem. Eventually I managed to escalate the rating of the it; at this point I can keep the system stabiliized and working OK all the way till PC shut down. But (and there´s always a but) the problem haunts me back when rebooting, so I need to get thru the whole process of installing drivers, configuring connection etc.all over again. Seems like a loss of hardware configuration???. I found out that the driver installs at IRQ 7 same as the USB-PCI controller and this does´nt pose a problem like I said till rebboting. My BIOS´s got two ways to manage IRQ´s, automatic and manual, but can´t figure out to assign the right IRQ. Another way out, what if instead of shutting down the conflicting USB-PCI driver I just go an unsinstall it?, Tx again.

    Easiest way to diagnose conflicting hardware is to remove the hardware from the PC that you do no need. This includes everything except processor, memory, and video. With the fewest things in the PC from the start, if it boots, turn it off and add 1 device at a time. Note where the error message pops up again. If it turns out all your other devices work fine until you plug in the wireless card, you can narrow it down to a problem with the wireless (or other device that it fails on).

This almost always seems to be an IRQ conflict that the BIOS can't resolve with its plug n pray skills. When this conflict is passed to XP at boot-up time, XP panics and blasts you with this error message.

Before you start pulling cards, go about pulling cards, go into the BIOS and change the IRQ of the on-board compnents, if you can, and also disable any on-board components that are not needed. (such as the parallel port, on-board ethernet connection, etc.)

Good day. In regards to your issue, if the d-link support agent told you already that its not compatible with your hp motherboard, you might consider getting a new wireless adapter. Better you can contact d-link again and ask them about a model of wireless adapter that will work fine with your HP computer. Its better to replace your wireless adapter than putting your entire computer in jeopardy. Conflicting hardware might cause instability and might crash your entire system

Hope this help you a bit. Have a great day and thanks for using Fixya. :)

Your need to use one or the other wireless manager applications - Windows or the application that came with the Mini-PC Card (Broadcom BCM94306MP). Sounds like Windows is managing the device. Check your Wireless Network settings.

2200bg card - weaker signals

Try using a different channel as there may be interference from other appliances. You are probably on channel 11 in the routers settings, so experiment with a channel from 1 to 10, but don't forget to change the channel of your wireless card also.
