I am using Huawei E5186s-61a for Wireless broadband which is provided by OPTUS. I have 8 Wireless clients at home. After upgrading router to 21.310.01.01.74 all clients disconnects from WIFI at the same time and it happens every hour or less. I connected a seperate acess-point, now it works OK but my access point range is not enough.
I did a complete factory reset. Nothing changed.
Is that possible to roll back to previous version?
I have the same device. They are notoriously useless and it is so frustrating. I would strongly suggest doing yourself a favour and buy something decent like a Netgear Nighthawk.
