I have this strange problem that when I connect over public wifi or office wifi, email and Google talk will not connect, giving me a network connection error. I have to disconnect from the wifi and switch to 3G to sync my yahoo email or connect to Google talk. I do not have any problem browsing the net over public wifi! BTW, when I connect on my home wifi, I do not have this problem. Any ideas what could be causing this problem?
Thanks in advance.
