Problem getting network/internet connection (in China)

I'm travelling in China and all the hotels I'm staying at have broadband in the rooms via direct cable connection. Most have connected to their networks right off, but a couple have failed with my laptop (and not others') and I've needed to have someone get me the IP/DNS addresses so I could connect manually. I'm wondering why this might be happening. Previously, I had a thread about how in the U.S. everytime I moved locations with wireless there'd be a problem getting connected, but this one is broadband. Any ideas? Thanks,

Acer Aspire One 722
Win 7x64
Atheros AR8152/8158 PCI-E Fast Ethernet Controller (NDIS 6.20)

Update: I just updated Atheros to the latest version on the Acer support site (9.2.0.412 Win7x64), but the problem remains.

 

I doubt you did an update. Judging by a version number you've installed an Atheros Wi-Fi driver.
Check this one out for an Ethernet.

 

I think you're right in terms of the update, but which one were you referring to ("this one")? The site I pulled the update from is Acer Support: Downloads & Support Documents - Netbook / Aspire One / AO722. Device Mgr shows the driver I have is current and the Acer site suggests there is only one version out.

 

Click on words "this one" in my previous post it's a link to a new version of the driver.
Acer never updates drivers anyway.

BTW I don't think driver update will help but that's something to start with.

 

No, the network problem is still there but that's a good site for drivers. Thanks.
