U301 WiMax card hangs on Mac


U301 WiMax card hangs on Mac

About once a day I, my wireless connection hangs. Running dmesg gives the following errors:

Jul 19 17:54:16 184-225-125-44 kernel[0]: dlil_output: output error retval = 37

Jul 19 17:54:18 184-225-125-44 kernel[0]: USBF: 1101.802        AppleUSBEHCI[0x4492800]::Found a transaction past the completion deadline on bus 0x24, timing out! (Addr: 4, EP: 4)

The only thing I have discovered that fixes this is to unplug the modem, kill the sprint manager software and then restart it and reconnect.

Is there a known fix for this problem? It is kind of annoying to have to do this. It happens about once a day and I am online for my two hour commute.

I appoligize for the issues you have been having with the U301 air card. We do not have any reported known issues with the problem. Can you tell me what version of Sprint Smart View software you are using on your MBA? You can retrieve that information at the top of the  Sprint Smart View window Help- About Sprint Smartview-Version.



Thanks for the prompt reply!


When I check for an upgrade, it says that no upgrade is available.


I don't understand what you want me to do. When I click on that link, I get the same exact zip file that I used to install Sprint Manager in the first place. How do I install just the device drivers?
