Model: Archer C3150

Hardware Version: V2

Firmware Version: [0.2.0 0.9.1 v005f.0 Build 160908 Re.51843n] updated to [2.0.0 0.9.1 v005f.0 Build 170807 Rel.57241n]

Hi,

If a new Router Archer C3150. Firmware Version was Build 160908. Setup done, everythink I've tested works.
Then I've upgraded Firmware as recommanded to latest Build 170807. Since then WLAN is not working correctly anymore. Only 2.4G visible, 5G not visible, instead toggeling Guest WLAN visibility. However nothing works.
When I try to sve wireles lan settings the following error pops up: "Error code: 9805 Corresponding Case not found".

I would like to use the new firmware since it has some more features like to configure the router as access point.

However I also contacted TP-Link support. This is ongoing for some weeks, I followed every suggestion like alternate reset, etc., but so far no success.

What can I do?
Has anyone applied a new firmware version already successfully? If yes, which version was it?
Thanks in advance

as I remember led is still on. I tried already different Browsers and devices. Everywhere the same.
After upgrade it reboots, than I have to do initial Setup again. This works fine till I press the save button. Then the Progress bar showing up someprogress, and the error pops up with around 40%. Same error as when I try to save wireless Settings.
Btw. I'm located in EU and tried Firmware for that region.
