Hi to all! Since I've updated to JB stock rom, I can't connect to some routers: it remains frozen on "connecting". I've found this solution: http://www.droidforums.net/forum/droid-4-general-discussion/239333-complete-jellybean-thread-32.html#post2404745 but replacing the wpa_supplicant file with that one solved my problem for example with my router at home, but it still gives me problems with other routers, so that I have to "switch" between the two wpa_supplicant, and it's very annoying. So, if someone still has ICS stock rom and has not updated to JB yet, could be so kind to post the wpa_supplicant file? I'd like to try if this could definitely solve the wifi problem. The file is in /system/bin and you need to be root to get it and to use a file manager which allows to access system files, like "File Manager" or "ES File Explorer" from Google Play. Many thanks in advance!
