      I confirmed that an external usb wlan adapter works and I am not seeing any dmesg usb error messages while the physical switch is OFF.

      Earlier, I tried multiple reconnectings of both the internal card and the physical switch to see if that made them work better and reduced/eliminated error messages. When I rebooted and then turned on the physical switch with all the wlan and bt modules blacklisted, no error messages occurred. After turning the switch on, I did start getting dmesg connect disconnect and other usb error messages. However, I was able to get ceni and wpa_supplicant to find a number of networks via scan. I was unable to connect immediately because of a problem pasting my 63 character password into the wpa_screen. By the time I got my act together (third attempt at stopping and starting ceni), wpa-supplicant no longer completed the scan.

      So, either there is a software issue involving the current intel driver versions for this card (iwl4965) or some of the usb hardware is dysfunctional.

      One question for the knowledgeable folks – wpa_supplicant takes an awful long time (?6-10 minutes, it feels like). Is that (a) common, (b) a reflection of the age of this computer, (c) something is broken <g>. The usb wlan adapter is using usb 2, not 1.1.

      Checking on speedtest, my download is 18 and upload is 3.7 (vs 80 download with the gaming laptop with an ac wlan/BT card).

        Note to moderator: The title of this thread should be WLAN/Bluetooth Card Continual Disconnects Block Function.

        The main error message with Bluetooth blacklisted and the bluez package removed is USB device connecting and disconnecting. No more opcode errors.

        If possible, please change.

        Thanks.

          Learned about software to test usb from usb.org/compliancetools. Runs in Windows. There are 2 versions for Windows XP. Although I have able to run amd64 kernels on this machine, the 64-bit version refused to install, while the “regular” (presumably 32-bit version did. However, the program requires a microsoft xml parser (msxml, version 6), which refused to install saying it wasn’t compatible.

          So, I may never know if this testing program (usb20cv.msi) would have detected a specific hardware error or not.
