I bought the AX50 a week ago and my nightmare starts. First one I used for a day and kept losing internet connection even with LAN and the device got very hot after ~2hours usage. The retailer replaced a new one for me to try. This one the internet connection with LAN is good. But the wireless connection keeps dropping. Sometime can search the 2.4G and 5G connections, but cannot get IP after connected. Even get the IP, very often the connection is without internet service, but at the time LAN connection is good (just like now I am experiencing). Keep rebooting the device again and again. Sometime I got lucky and I can use the wireless connection for a period then it drops again! Have been calling the support hotline and they tried to help by telling me different settings to try, the problem is still there. I am so disappointed for the poor experience I have with the product.
