Re: Weird WLAN problem after stupid upgrade attempt
I've updated to the Q2D08 firmware now. Whereas the '07 firmware seemed to run the test /wlan ok, but the wlan card wasn't visible to the regular OS, now when I run the same command on the '08 firmware I get ok test /wlan Device /wlan not found. ok So what's the verdict. Do folks think I should RMA this thing? It seems like it got busted merely via software - which one would normally not expect to be possible.

Re: Weird WLAN problem after stupid upgrade attempt
Well, darnit. Looks like things are flaky. Here is the procedure and the results I just got. - Flash q2d07.rom test /wlan worked fine - Flash q2d08.rom (to verify that 08 is causing problems) test /wlan fails - device not found - Flash q2d08.rom (because I wanted 07 and mistyped the filename) - Flash q2d07.rom test /wlan fails - device not found - Pull battery and AC, wait 20 seconds test /wlan fails - device not found - Flash q2d07.rom again test /wlan fails - device not found test /usb - shows port 0 in use, same as on my working machine. This is with no USB sticks connected. When a USB stick is connected, then ports 0 and 1 are in use. So now that test /wlan is failing with '07, that encourages me to believe a simple hardware issue is occurring. Although the WLAN card is a USB device, I'm assuming it is surface mounted and there isn't any sort of physical connection that could have shaken loose is there? I'm not opposed to the use of a screwdriver, but I haven't bothered yet since I doubt that I could do anything.

Re: Weird WLAN problem after stupid upgrade attempt
Tom, I would RMA the unit, going through Adam Holt instead of the normal process. We want to see this unit ourselves before sending it back to the manufacturer, as we haven't seen this problem in the past. The WLAN is a separate module, surface mounted to the motherboard. There have been occasional cases in the past where insufficient paste was present to properly solder it down, but they were caught in board level testing before assembly, and haven't been seen on mass production units. Given the lead-free soldering process we are using, solder cracks are also a possibility. If you decide to take a look yourself, all you need is one #1 phillips head screwdriver. I wouldn't even disconnect the LCD, just move it enough to get to the four screws holding on the back cover located behind it. A total of twelve screws need to be removed to get to the motherboard.
