ZYXEL VMG8823-B60B firmware 5.13(ABEJ.4)C0 update - cannot login

kzlatak

Hello, 

I update firmware in my modem to the latest version, modem works normally but it is not possible to login into it /I tried my login and password, then I did factory reset and tried admin 1234/. Still no success.

Please, any idea how to login?

Thank you very much for any help, I am desperate now.

Hi klatak,

Can you please help to provide serial number? It’s on back label of your device.

Hello,

I also have this problem. I received the device from my ISP, set it up, connected and stuff and decided to update. After update I could not login to administration, it did not hurt me though because I had everyhing set up. Today I performed a hard reset (by pressing the recovery button on the device) and I need to login to administration to set up Wi-Fi. I can not because when I add right username and password ("admin"/<password from the stick on the device>), the page just refreshes and nothing else happens.

Hi Ucitylek,

Could you please clean browser cookies and then connect to GUI to try again?

May I know have your ISP name and fw version?

Unfortunatelly, I do not remember what firmware I downloaded but my ISP is also T-Mobile Czech Republic so maybe Starball could know.

And the problem does not occur on one browser or PC only so I do think clearing cookies would help.
