ipconfig /all under the command prompt will answer the question of your router’s IP address.
It’s step #1.
If you have internet - as I recall from your post, but I could be mistake (busy day here, too) - your router has an IP and should be accessible.
Ok, I have these addresses via ipconfig /all :
(truncated by me)
Link-local IPv6 Address . . . . . : fe80::e...C%7
IPv4 Address. . . . . . . . . . . : 68.67.....221
Subnet Mask . . . . . . . . . . . : 255.2.....5.0
Default Gateway . . . . . . . . . : 68.67.......1
DHCP Server . . . . . . . . . . . : 68.67.......1 (same as default gateway)
and a bunch of other Greek to me. (I assume the “physical address” is not relevant here.)
Which am I supposed to plug into my browser?
Oh, wait - it’s supposed to be the default gateway...
Giving it a shot...
The browser (Brave) came back with :
This site can’t be reached
68.67.....1 refused to connect.
(I edited out a couple characters to post it here as I am not sure what the security risks might be.)
Anyway, that’s the same message I got this morning working to find an address via Settings. (I also tried Edge: the wording was slightly different.) I think it is the same address as this morning, but I am not sure.
The phone is still connecting to the web via the wireless router, just fine.
