Simply there is no option to change it. I need to change it from 192.168.1.1 to something else
I will share the admin menu screenshots:
I am trying to use this router as a WiFi extender it has been reset to factory settings. It is a WSEE router and model is WUTG13. I have tried to install other software but there is not a single one available for this router.
Unfortunately my answer is that the settings of this router/modem cannot be modified this way.
Your router is the modem of your previous ISP, which I suppose was WSEE. It was fabricated by a company called Stel Fiber which doesn't exist any more and its domain-name is actually for sale.
Your ISP has probably installed a stripped-down (or locked) firmware. Below are the administration screens of the firmware as they are on your computer compared with the Stel Fiber firmware:
The setting you're looking for was supposed to exist in the "WAN" section of the settings. However, this section is totally missing for you.
The original name of the router was GPE600. The Stel Fiber support-site has disappeared, but I have found it in the Internet Archive, with the idea of somehow overwriting the existing firmware with it:
Unfortunately, the Internet Archive has only archived the page, but not the firmware files to which it points. I have tried all the versions of the website which are found in the Internet Archive, but the download links for the GPE600 firmware were not archived in any of them.
Conclusion: Your router is locked-in to the firmware with which it came. That firmware does not permit you to set it as an Access Point. If you can, you may try in the router from the new ISP, to disable its DHCP server function, in the hope of unifying your entire internal network. The WSEE router will then supply it (and the entire network) with a good internal IP, with no need to change the internal IP of the old router.
If this will fails, then you need to get another access-point, rather than the GPE600.
You will need to explain exactly where you are with your settings aas it is all a bit up in the air.
I would suggest the current router isgateway and also x.x.x.1, the old router no longer issues IPs ( not act as DHCP server) leave that to the current router.
Fix you old router to a value within the realm but not one able to be given out by the current router's DCHP server.
You may wish to alter the IPs available to start late or stop short so that you can squeeze in the old router.
Ensure you old router points to the current one as gateway and copy the DNS entries to the old router.
