Into Tomorrow With Dave Graveline listener Terry in Carthage, Missouri listens to the podcasts and asked the following question:
I have a Note 4 on Verizon and a Nexus 7 Pad. Both have been updated to the Lollipop OS. I have a problem with my Nexus Pad connecting with my Note 4 on the hotspot. I had no problem before the update. Now, I enter the password and it show connected, but it keeps saying “can not authenticate.” So I can’t actually get a signal and use it. I’m at a loss and wanted to see if you guys could help me.
First thing you should do is a little detective work. Can other devices connect on the Note 4 when it’s running as a hotspot? Can the Nexus 7 connect with other wireless access points?
In other words, is this strictly a problem between that specific phone and that specific tablet? If it is, then you have two options you can try. The first is to have Lollipop “forget” the wireless network. If you display your list of networks, locate the Note 4 in it and long press (press and hold) that network. Choose “Forget this network” from the menu that pops up, and try connecting again.
The Nuclear Option
If that doesn’t fix it, then you’re looking at the dreaded factory reset. It’s really the only way to be certain these two devices try and connect with each other while bringing no baggage from past configurations.
For what it’s worth, we’ve read about a lot of people complaining that the 2012 edition of the Nexus 7 has issues with Android 5.0. Hopefully it’s something the Google engineers will get sorted out for you!
