Rechecking older partially supported devices

I would like to know if there is any possibility to quickly check or supplement the operation of older devices that have problems with operation, such as WIFI.
I have in mind the Linksys E1700, which has problems with the operation of the WIFI network.
A newer device with comparable hardware is the Bolt bl100.
Maybe this existing code could help in refactoring the code for the E1700 device?

Likely you have to check in place, mt76 driver is being actively developed. Fill a report in mt76 if there is still any problem XOR ask to clean up wiki.
