Hi I just bought nexus 7 few days ago, and I have not been able to connect to wifi. I do not have any access to home wifi, but I've been to school and mcdonald's to get wifi access. However, I cannot use them. It said that it was connected to those wifi, but still cannot use internet. I think it's because both wifi providers (my school and mcdonalds) requires user to Login in order to start using wifi, while not requiring WEP or WPA/WPA2. (such as user agreement page for mcdonalds) Any thoughts on how I can open those login screens? it seems like chrome on nexus 7 can't do that job.
