I had a heck of a time getting my new Comcast 2go wimax connection working on my Windows 7 x64 laptop.   The comcast system requirements said XP and Vista but had no mention of Windows 7 nor 32 or 64 bit.   I felt confident I could get it working anyway.

The comcast installer didn't recognize it was 64 bit so after the software installed and I inserted the zte tu25 usb modem, it would get an error saying the drivers were not successfully installed.

The reason why was because the comcast software installer wasn't detecting my laptop was x64 so it was only installing the x86 drivers.

What I had to do is use 7-zip to open the setup.exe file as an archive, browse into where the driver files were at and install them manually.    Here was the location I used:

Setup.exe\CommonAppData\Comcast\Connection Manager\drivers\wimax\Vista\64Bit\Beceem\Beceem 5.2.4.4\

It actually installs the device as a network adapter named "Beceem Communications Inc. Tarang3"

Hope this helps someone else who may be having trouble installing Comcast 2go / WiMAX on a Windows 7 pc.

Yikes, After installing the RTM version of Windows 7, I'm unable to get this to work!

My above post was done on the RC version of Windows 7.  I assumed that this should have worked with the RTM'd version as well, but apparently not!

I'll keep you posted on any additional fixes or workarounds I find in order to get this resolved.   I would appreciate any feedback as well.

I tried Windows 7 RTM x86 instead of x64, and I was able to sucessfully install the drivers.    So it may just be an issue with the x64 drivers.

I'm going to try one last thing with x64 install and see if it works.   I'll post an update with my results.

Finally!   I was able to get the drivers to successfully load in Windows 7 RTM x64.   The problem was due to some of the files in the 64bit driver folder being shortcuts and not real files.   Two important files had ".ale" extensions, and if you opened the files in notepad, it was just a redirect to another folder.

What I ended up doing was copying the files out of the folder the redirect was going to (CommonAppData\Comcast\Connection Manager\drivers\wimax\xp\32Bit\Beceem\Beceem 5.2.4.4) and put them in the 64bit driver folder.

Here's the incorrect files:

I hope this helps someone successfully get the Clear / Comcast USB WiMAX modem installed!
