I had to update the firmware on my WPC54G to solve this particular problem.
Also, do not use that driver. Go to the Linksys downloads page to download the latest driver for your version number of the WPC54G.
ASIDE: when connecting, I find the Linksys wireless connection utility to be troublesome on some systems. I disable it and use the wireless utility built into Windows XP. Make sure your XP is updated to SP2 to have the latest version of this utility.
I am running XP V.2002 SP2 on a Compaq Presario 2190US ? 2.40GHz, 448 MB RAM - using a Linksys Wireless-G 2.4GHz Notebook Adapter (WPC54G). Previously, the wireless was working just fine.
However, today, it is not. With the adapter inserted in the adaptor slot, there is no recognition of it from my computer. Generally, there are two LEDs (power and link) on the card that light up. However, now neither lights. And there is no wireless connectivity.
I uninstalled the Network Adapter driver and restarted the computer and the driver reinstalled. It now reads: ?National Semiconductor Corp. DP83815/816 10/100 MacPhyter PCI Adapter?. The Device status reads: ?This device is working properly?. The ?Troubleshoot? has produced no results. Device usage is on ?Use this device (enable)".
I have tried the Adapter in another computer and it works fine. Likewise, I have tried another Adapter in this computer and there is no sign of life.
I also uninstalled and reinstalled the software for the Adapter. Again, with no results.
What next? What else can I try?
