@tesla-s3xy Hi, i'm facing the same issue with AX20 router, RE 305 is always switch to inoperable after some days. when restarted means unplugged it's working some days then connections not possible....

@Sunshine hi Sunhine, thanks for your reply. the router is well configured and started to use. the issue occurs when i tried to connect the created wi-fi network locally and not related to my ISP....

@Ravindra21 Ravindra, i just checked my ISP and working method is different, no MAC update needed here. do you have any other idea? when the router phisically switched off then working some hours...

@Ravindra21 thanks for your reply, i'll check with them..

@peterc12 hi, i faced the same issue. did you found any solution?
