The Wiki recommends adding a heatsink to the WiFi card as it might overheat and fry otherwise. Does it work with the stock firmware?
And the Wiki says that some versions can destroy the cal_data area, resulting in lost WiFi.
Check the Wiki: https://openwrt.org/toh/huawei/hg556a
no it doesn't work with the original firmware unfortunately
So either your card overheated and is literally toast or you lost the cal_data partition. I would rule out the cal_data partition problem first.
is there any guide on how to fix that
fix it using this method
So it was a lost or corrupted cal_data partition!
yes it was thanks for the help
