I am trying Putty, with NOkia X6 device (symbian s60 5th edition), and it works flawlessly when I am over 3G mobile connection, but if I select wifi, application hangs (sometimes it exits with a error that could not find server), and could not close it anyway until I reboot.
Despite this bugs seems duplicate of #2616687, it ISN'T, because in my case there's no net missconfiguration. Everything works OK from other PC connected to same AP.
I've tried with a no-ip.com address, and also with internal IP with no luck.
Despite I can still use the app over 3G connection, I would thank you to make it work over wifi too.
