Are you using the WAN IP or the WLAN IP ?
wifi and ethernet don't use the same IP by default.
I'm not entirely sure and cannot check right now because, as you know, I can not enter the Antminer s1's GUI through my browser. But before it started mining (before I scanned for/setup the antminer's wifi to connect to my router wirelessly + "shutting down"...not deleting the WAN) I was using the antminer's IPV4 address (whatever that is, I believe it was in the Network>WAN section, I'm not sure and I'm not familiar with the miner's GUI but it's the same page where I can choose/set a DNS address also [and I think the option to check DHCP client? but maybe not]) The IPV4 address, 192.168.2.206, is what I was using to successfully access the GUI through my pc's browser. My router's IP address has the same subnet value (2) making it compatible. Everything is still mining fine, I'm checking the progress through my pool's website, but still just can't gain access to the antminer's GUI using it's IP address in the browser of my PC- the PC is connected to the same wireless network that my antminer is connected to/mining on. Thanks for your reply also, really. I really do appreciate even taking the time to attempt to help out, If I can return the favor in any way, please let me know.
