Cannot connect wirelessly to internet by USB adapter

Hi all,

I got a problem with my newly installed win 7 64 bit.

When I tried to connect it wirelessly to the internet (using the wireless USB adapter --> Zonet ZEW2546), it cannot detect any single network available, even though the router is just one floor below the PC.

But, when I tried to plug the USB adapter to the other PC, which runs on Win XP, on the same floor as mine, the adapter works perfectly, and I could surf the web from the Win XP.

What do you think the problem is? Hardware or driver?

Btw, I have specifically looked for the newest driver for the USB adapter (which also supports win 7 64-bit) and installed it to the new system, but still to of no avail.

its a driver problem please contact service provider or copy xp driver all files to win 7..try this......

has anyone ever sloved this issue? i am in the same boat after moving from XP to 64bit W7. W7 does not even recognize the ZEW2546 as nothing shows up in the device manager. it makes a strange tone when i insert the device in the usb port different from the tone it makes when i insert something that it recognizes like a flash drive. the device is supposed to be W7 compliant and there is a 64 bit W7 driver in the software but when i run the setup, i get the message Sorry! We do not support this operation system !!". when i plug it back into an XP machine it works perfectly. i have emailed the vendor but have not received a response yet.

okay markgil..

I have solved this prob, and the way I did it is that, I first connected my PC to the internet through ethernet (wired one), and then I plug the zonet USB dongle in.

Win 7 will automatically look for driver and installed it by itself, and
ta-da.. the zonet works.

P.S: do not install the driver by itself (download from zonet website), as it will not work. I have tried this.

thanks for the reply jemping but i actually solved this last night in a different manner. i received an email from zonet that told me to manually install the driver. i did so but it still didnt work because it was an unsigned driver and W7 would not recognize it even though it was loaded. a quick google search located a program which fixes unsigned drivers and after running it and rebooting was good to go. now if i could only get it to connect to my WRT54GL i would have internet access!

Theres a driver that works great for either 32bit or 64bit win 7:
