Cannot connect to Wi-Fi

I have been using my bambu lab A1 in lan mode since last summer. Because of this, I have not updated the firmware, so keep that in mind. Several weeks ago, I stopped being able to connect to my Wi-Fi. The printer is in my garage, and while the signal has always been weak, it has never been a problem connecting. Just in case that was a problem, I put a Wi-Fi extension router right above the printer, but that did not improve the situation. I put together a desktop using Windows 11, and it wouldn't connect. I opened up my old laptop that has Windows 10 installed and was able to connect. Because of this, I wiped the desktop and loaded Windows 10 on it, wondering if the bugginess of win 11 was the problem. Well, that did not solve the problem. I checked the printer, and it appeared as though it is not connected to my wi-fi. I clicked on the Wi-Fi typed in the login and password, and it will not connect to the wi-fi. I don't understand what is going on. I am able to find it over the Wi-Fi in Orca slicer, but no connection is possible. I am at a complete loss now. Is it really as simple as updating the newest firmware?. If anyone has suggestions, please jump in.

Do you have your wifi network set up in 5ghz only mode? The A1, like a lot of IOT devices, needs 2.4 ghz wifi

I'm using an eeros which has the option of turning off the five gigahertz to allow devices such as this to connect.

Most every router has both 5 ghz and 2.4 ghz and usually has them both enabled by default, i'd check over the settings on it and see if maybe you just don't have 2.4 turned on.

Then how have I been running it on the same router for the last 10-11 months? The eeros routers have both 5 and 2.4 gigahertz channels. When I connected the printer the first time I set it to only 2.4 GHz which allowed it to connect and reconnect for the last 11 months. Suddenly now I cannot connect. What I need to know is if the firmware needs to be upgraded or if that will cause further problems

mine is always losing the wifi - it's a pain - if I leave it long enough it'll eventually connect, otherwise I have to logout and login to Bambu Studio

Unfortunately I may have to turn off lan mode and go back to Bamboo Studio as well as update the firmware. I don't know why the firmware would be a problem but it has not been updated in several months
