i think you should delete the whole public test folder and allow in to install again then you should be able to play again you can find the "public-test" folder in the legions overdrive folder.
the router might have a default username and password depending on the model just google the model of the router and see if you can find out the default user/password
I enjoy it i think its good tbh the only thing i don't like at the minute is the amount of tokens to unlock each class(i haven't played since the new patch) and the weapon speed inheritance its way to low that you can almost out run you disk when you shoot it. they should at least increase it to 50%
