Look if you choiced the correct country/region in VoiP configuration . Then you should activate the logging for Voice events in maintainance to see if the call reached you . Check if the VoiP configuration is ok , but this is not easy to configure . With my ISP i had to enter 2 IP adresses instead of the server URL of the…

So i see you have the right FW . Blocksize could be adapted in the FTP Program ? https://www.ibm.com/docs/en/zos/2.4.0?topic=protocol-blksize-ftp-client-server-statement

There is no Zycel ftp server anymore . Isn’t it normal during such a process that LED is blinking and you have to wait for some Minutes ? You could try a ftp Program instead . You cold post the cli commands and reactions may be someone else can help you about . If found this history of FW-s :…

Yes this was meant like here : https://community.zyxel.com/en/discussion/21067/how-to-update-the-firmware-by-ftp Sometimes you need a version between the older and the newest Version . Someone tried this and said you have to change the directory to "firmware" with command "cd" . So good luck , anyway ;)

So it seems youre locked out of this device . Is it possible to login via FTP access from a device in the local Network with cli of Windows or a Program ? Only some freaks can make such an update via Hardware flashing …

Do you have the option for manually FW update ?

Maybe you can set the Router in bridge mode and then make the connection with a WLan Router behind . For replacing first look i you can login to the Router via SSH . Do you alrady got the newest FW ? https://www.zyxel.com/service-provider/emea/en/products/ethernet-cpe/ethernet-iads/ex7501-b0#resources_downloads

I think you cannot combine this scheduler rules with wifi ….

With mobile devices there can be an issue with WLan "DTIM Interval" to not react , the value should not be to high "1 ms" is ok .

The ISP can configure the device via TR-069 i think you cannot block this . You can ask your ISP which ONT Modem is allowed to replace the Router , may you can buy it or your ISP sends you one . This device has to be registered by your ISP afterwards to be adressed .

Did you made a hardware reset over the reset button ? https://www.youtube.com/watch?v=fFtNi7lEOt8&pp=ygUSenl4ZWwgcmVzZXQgcm91dGVy

Sorry but no . My hint with the user group instead of admin was ok but i dont have enough knowledge about the hole thing . Someone with real expertise would know what happend exactly and how to solve the Problem . May be you can email for support …

I dont have these lines : ["DefaultGuiPassword":"", "ResetDefaultPassword":false,] What happens when you change to ["ResetDefaultPassword":true,] and make a reset ? Or delete these lines . » But all this is now speculating …

So my last idea is to look into the config file if there are other users exept the known two ones . This is very strange, may be there is a special unknown history or information about this device …

This is strange , is it a normal bought device with you as the owner ? I would try this trick : create a new user eg with your name , test it and then delete the "false admin" may be the "default admin" reappears . 2. export the config file and search for ["Username":"admin",] and the values ["Enabled":true,…
