New to the site. Don't know if this has been posted before but if it hasn't, it may help someone else. If you are having a problem connecting your Acer A100 to wifi you may want to check this out. If you have any lower case L in your router password please remove it. The reason is that due to Androids great wisdom they place a number 1 in place of the lower case L. If you watch it when you are entering your password you will see that it comes up as a number 1.This happens not only in my Acer but my son's as well. This only happens as far as I know when you are entering a password in the password box. Other boxes seem to be ok when entering a lower case L. Acer help told me that this was normal. You figure that one out.
