I been using the same robot and internet for almost 1 yr. Then suddenly it stopped recognizing my wireless setup. I try log in, using the same password, but it says it's incorrect. I made sure to check it with my company, and password is correct. I also have another wireless device, and it will let me online, using the same password. How can I fix this? Of course, I've already updated and reset the device. I have the express model.
