Sierra 320u aircard upload speed limited at 1Mbps after firmware upgrade.
Need help! My Sierra 320u aircard upload speed limited at 1Mbps after firmware upgrade.
At the last procedure occur "AT CONFIG Update Failure". but aircard can connect to the 4G internet normally (I live in Thailand using Truemove H 4G). I'm not sure if this is the reason.
How can i fix this? Thankyou

yesterday I tired reinstalling lastest firmware with windows 7 (32 bits) and remove sim card from aircard before installing (first time i didn't)
good news is it's successful (No AT config error message at all). bad news is upload speed still limited at 1.0-1.2 Mbps.
Anyone can help? Thankyou
