I'm having troubles to access the Router Administration Page of our D-Link DIR-600 router and this is happening for a month or so.
In this short past, I'm 100% sure I could log in it successfully as I needed to open a range of ports in order to download the new Elder Scrolls Online. But now, I can't.
Initially, with a bi of paranoia, I thought my brother changed the password to limit my bandwidth but he opened the panel in his mobile phone in front of me using the password he said it was (the default admin).
The curious thing is when he asked me what address I was accessing and I said
192.168.0.1 he said he was using
192.168.1.1, but I ran a ping over this address and it's unreachable.
Is this possible?
As an additional details, just in case, I'm using a TP Link TL-WN851ND wireless adapter.
From this stack I'm now aware of the fact some routers can block access through wireless adapter, how can I explain the fact of the mobile phone access or the fact I accessed it some time ago using the same device?
In case the answer for this question is something related a specific setting, how could I revert it without a factory reset (which as weirdly as it seems, may not be working too).
As requested, the ipconfig output
