Hi all
This isn't a game glitch but a networking bit of weirdness that I can't understand so wanted to pick your collective brains.
Since we moved into our current home, we have had the same modem/router. It had a network name of (lets say) flotsam. I had also plugged an extender into a WAN port to cover the back part of the hosue. Lets call that network jetsam. Depending where you were in the house your device connected to whichever network gave got the best signal, or you could manually select whichever.
We recently had to replace the modem/router and it came pre-configured for our provider. Lets call that network lagan. The old modem/router is no more, and has been disconnected, but the extended network (jetsam) was again plugged into a WAN port.
We set up the devices for lagan, jetsam showed up as an available network, and off we went.
The weird thing is my phone (and no other device) keeps connecting to flotsam. All three networks show up and I can connect to whichever one I want. All three can also have different signal strengths. As I type this, the pc is connected to lagan but I could connect to jetsam and those are the only available networks. Sitting in the exact same spot my phone is connected to flotsam, and jetsam and lagan are both available.
Any idea what is going on?

I would also love to know why my ancient network which is TWO modems ago still shows up as an "available" network on many of my devices. Just out of curiosity, I tried to connect to it using the old password, but of course, it wouldn't work. I am surprised you are able to connect to the old network names. I must say that I noticed that when I recently upgraded my internet service package to a higher speed, all those old network names are gone on my desktop, although they are still listed on other devices. My ISP provided me with a new WiFi 6 router (802.11 AX protocol), so I don't know if that had anything to do with it. I had just set up a new 802.11 AC protocol router. When I did, I had the ancient network name, my most recent two network names - 2.4 Ghz and 5.0 Ghtz bands - in addition to the two NEW network names - 2.4 and 5.0 Ghtz names. So there were 5 of them! But when the technician set up this new 802.11 AX protocol router, they all disappeared.

I am quite bewildered by most network issues, so I am of no use here!

Some info below...

WiFi Names

EDIT: After reading the posts in the link above, I remembered I had a WiFi extender upstairs which I had completely forgotten about. I unplugged it and all my extra network names disappeared - on ALL my devices. So THAT is what was broadcasting the old names.

So it may be the fact I kept the extender. Makes a bit of sense I suppose
I will unplug it later to see what happens.
Thanks for the info Draclvr

Please let me know what happens. I am curious to see what happens when you unplug your extender. I think all I need to do is reset mine to factory and then reconnect to the new network.
