@Kevin_Z Yes and yes. I have to rescan the drive under the advance tab to get it to work again like most others on here. I have already tried all suggested fixes and nothing will keep it online, only...

@Kevin_Z Model: Archer C1200 Hardware Version: V3 Firmware Version: 3.0.6 Build 20200401 rel.71690

Unless tp-link fixes the firmware I do not think we will be seeing this fixed. Most likely not a lot of users use this feature on the router so I am sure it is not a high priority for them.

@don54321 Yes, mine also can be rescanned and then I can access it again. Seems to be a common problem with tp-link routers. Not sure why they didn't fix it on the last firmware update.
