wifi won't connect

No, the network names and passwords are different for each house. We have 2 accounts.

My gateway is from xfinity.

I just checked my computer again under Settings...it shows that I am connected to the far-away network.

I just looked at my iphone...I haven't touched it, but it has changed over to the far-away network too.

Are you able to show the local wireless networks and connect to the wireless network name that would be coming from the home you are currently in @4cu66YF? If you are able to see the wireless network name and receiving an error that the password may be incorrect, you would need to verify the information from the gateway/router. 

An additional step you can take is to "Forget the Network" and start a new connection to the wireless network to submit the proper password. Do you currently use an Xfinity xFi Gateway or use your own personal cable modem/router?

If I left-click on the wifi icon on the lower right of my computer screen, I can see several "available" networks. These include both my summer and winter networks (plus some apparently here in my neighborhood). I CAN connect to my far-away winter network, but NOT to the one here in my summer home.

I don't know the specifics of my gateway. It is from xfinity, NOT one that I own.

I might as well try to Forget Network, and then add it. What have I got to lose?!

BTW...my computer is acting strangely. This morning it would not start. I went away for a couple of hours and tried again. I got an error message about doing a SETUP but I clicked Continue and Restart and it came up...even restored the pages I had open last night.

My computer is a Dell laptop 2019. I already have to use a wireless keyboard, plus it has been making a low strange noise occasionally. Probably time for a new one.

I will try Forget Network and get back to you.

Thanks!

@4cu66YF I just had the same problem with my dad's laptop the other night. It wouldn't find the signal it had previously connected. His device is also an older model and "forgetting" the signal worked for him. Hopefully, it works for you as well. If not, I'll be on standby just in case.

Forget and Reinstall did not work.

I read something in passing about the Network Adapter...???
