DNS Issues with Wireless Desktop

[suzannem]

I know I don't have my computer stats in my profile, but I had to go somewhere I could get online first. Basically, I've had sketchy internet problems since I moved. Sometimes my internet will run great, other times it just comes up with the DNS error. We have a Mac Airport Express 802.11n router and I'm using the ALFA 802.11g wireless USB adapter. I tried to test it by connecting to another person's open wireless in our building, but still had DNS issues. I tried switching adapters, resetting everything in ipconfig, using Google's Public DNS settings, and my roommates haven't complained of any problems, but I'm the only one with a desktop. I don't have a firewall running.
I get both "Windows can't communicate with the device of resource (primary DNS server)."
and
"DNS server not responding."

What should I try next?

Thanks,
Suzanne

Find you exact model here.
ALFA Network – WLAN, WiFi phone, ADSL, KVM, Bluetooth, PoE Products -- FAQ
and verify that they have not released a updated driver/software package for your wireless adapter.
that is the quick first suggestion. Since they apparently made more than one wireless g model though I can't go directly and look for myself based on the information provided.

I have the Alfa AWUS036H 1000mW 1W 802.11b/g USB Wireless WiFi network Adapter
I checked for an update automatically before it wouldn't connect anymore, supposedly it's up to date.

Auto updates aren't entirely reliable. I honestly had not even heard of this company before your post here.

Not sure how reliable a company is that puts it's own driver downloads on a remote site... no wonder the auto tool didn't work.
