Oled switch disconnecting issues

So i recently purchased a OLED switch. i was using a switch v1 before but wanted to upgrade to the oled for the obviously better screen and increased battery life. I had zero issues playing for the full 2-1/2 hours my switch v1 would give me in the same game ( i like to TZ an entire game and hunt heralds) so i try to do this on my new OLED and after about 15 minutes i get a connection error screen and get kicked. this has been happening NON STOP. i get 5 -15 minutes tops. i have been making passworded games in order to re-enter after the kick and pray i didn’t die and loose a bunch of EXP. regardless i tried looking up how to fix this from changing my Wifi to 2.4G band and locking my ip address and other such fixes and nothing is working. even tried getting off my router and using my cellphone hot spot. the only fix i haven’t tried is plugging into ethernet directly (i didn’t get the switch oled dock that has this but i got one coming today). even still i don’t consider this a “fix” as my old switch did this no problem but the OLED cant handle it. even still if plugging into ethernet is the “fix” the whole point of going for the OLED was to get that un-corded freedom and now I’m being told i have to plug into ethernet. which is even harder than plugging into power.

is anyone else experiencing this problem or is this a unique to me issue? is this a known issue and I’ve just spent a bunch of money on an OLED for essentially nothing. any help would be appreciated. thanks in advance.
