I've had this issue before and I think upgrading to the hyperwrt firmware and it fixed it. However, I want to keep the stock firmware as it is more stable and i dont need the added features. Anyway, has anyone else had this issue using the 4.21.1 firmware? Is there any way to get an older version of the firmware? Any way to fix this version to get it work? I did a reset after I put this firmware back on there. Any ideas? Thanks.
