Attansic LAN vs. Vista trouble? Kill the power!

I recently bought a couple a HomePlug adapters to see if they would get me a more stable network connection over wifi. However, as soon as I connected them and fired up my PC I started getting all sorts of network trouble. DHCP would work, but DNS wouldn’t, leaving me unable to surf the web. I now turns out that all this was due to driver issues with the onboard network adapter on my Asus motherboard. This ‘Attansic’ or ‘Atheros’ adapter has apparently been causing issues for many people.

The DNS trouble happened with the driver that was supplied on the CD that came with my motherboard. This could be an error specific to the combination of this NIC and the HomePlug adapters, but I was unable to connect properly without updating the driver. Once I did this (through Windows Update), Vista would boot very very slowly. I would take half an hour or more to boot, if at all. This turns out to be a common problem. Many people have reported similar behavior in forums.

Undoing the driver update by going back to a previous ‘restore point’ would allow me to boot properly, but without a working network connection. This is when I came across a very simple solution that worked for me. First you install the new driver. Then you shut down the computer. Once it’s off you either switch off the power supply or disconnect it from the mains for a few seconds. That’s all. After that my PC booted OK with the new driver and HomePlug turned out to be pretty cool. Stable and noticably faster than 802.11g.

EDIT: It appears I’ll have to repeat these steps every time I ‘cold boot’ my PC… grrr…

  2. When I try to enable or disable my LAN in network connections, my computer locks up. Does this occur for you also?

    I was unable to find any other articles of similar nature to yours here, do you remember what forums you found similar problems in?

  3. The power cycle seems to have permanently fixed mine, I am not required to repeat the steps you followed in order to make my PC work.

  4. Hi Sam. I can reboot my PC as often as I liked, but with real cold starts the problem pops up from time to time. Disabling or enabling the adapter does not hang my PC. I’ve done that very often whilst troubleshooting.

    See for more info. The problem has been discussed quite a bit on the Asus forums.

    For me it seems I’m stuck cutting the power until a newer driver is released that will hopefully resolve this issue. One thing I’m considering is the solution offered in this thread:

    But since this requires me to open up the PC I haven’t gotten around to it.

  5. Ok, thanks for the links.
    I reckon i can put up with the occasional need for a power cycle, I haven’t had to do it again since my last comment.
    At least until new drivers are released anyway.

    I have a problem with the newest drivers on the ASUS site as it is (under the 32 bit vista category). It says they are not compatible with the OS im using… which doesn’t make much sense.

    But hey, It doesn’t seem to be that big of a deal if it only happens occasionally. It’s not worth my trouble to reinstall windows, remove the battery and all the rest.
