is showing up on my wired connections to the router on Port 05.
I tried blocking it but I lost internet connectivity.
Looks like its something to do with the Netgear router but not sure what.
My main router login is from port 01 (192.168.0.1) and works fine.
If you put in 192.168.0.5/ in a browser bar it comes up with a login and password box, but nothing of mine seems to work, and I did try admin/password.

Huh? What, exactly, does "Port 05" mean to you? At what, exactly, are you looking? What, exactly, do you see there. Copy+paste is your friend.
What, exactly, is your (unspecified) "the router"? Look for "Model" on the product label. Firmware version? Connected to what?

"tried" _how_, exactly?
> [...] but I lost internet connectivity.
Not a useful problem description. It does not say what you did. It does not say what happened when you did it. As usual, showing actual actions (commands) with their actual results (error messages, LED indicators, ...) can be more helpful than vague descriptions or interpretations.
> My main router login [...]
Is your (unspecified) "My main router" different from your (unspecified) "the router"?

Is this ".0.5" somehow related to the mysterious "Port 05" above?
> Any ideas?
Provide a problem description which makes some sense to someone who can't see your equipment, or how it's connected, or how it's configured, or what you're doing with it, or what happens when you do it?
Don't invent your own technical terms ("Port 05") which make no sense to anyone else?
> All I meant by Port 05, was it is IP address 192.168.0.5
"Port" has a well-accepted meaning, different from "part of an IP address". General advice: If you mean "192.168.0.5", then _write_ "192.168.0.5". It's not complicated.

With my weak psychic powers, I can't see what you found, or guess why you thought it was unhelpful.

"the device"? Or is that your question?
If it's a gizmo which is sold to many device makers, then it might be unrealistic to expect anyone here to identify it based on (what looks like) a MAC address and "mysimplelink".
If I were trying to identify some mysterious device which appears in an Attached Devices report -- And I'm only guessing that that's what you're trying to do -- then I might try some basic detective work, like, say, powering on/off every "smart" Internet-of-Junk device which I could find, and see what comes and goes.
I have no better idea which devices you own than I have which router you're using.
