I upgraded a ET1N0 from GB to JB using the ET1N0JCCRU01701508.zip and it went all good. It installed and booted as expected.
However when I try to connect via wifi to a phone using phone's wifi tethering it fail to connect.
I can connect Wifi to an access point, but not to a phone.
Is there a wifi profile limitation for the JB image ?
I had to downgrade the unit back to GB since it is required to do tethering.
Have anyone seen this happen? if so is there a solution?
I have a second ET1 with the JB version installed that I will do more testing on it but this is a show stopper on populating a JB upgrade for the device.
Just for the record. This error is caused by the 802.11d setting
I disabled the setting and it is working now.
Settings - WiFi - Menu key - Advanced
And unchecked the 802.11d setting
I have seen this 802.11d setting with problems on other wifi devices, to this date I never seen an installation where this setting do anything better. At least in my experiences on warehouses.
