I have a Prevail thru Boost. I tether with Foxfi and pdanet for Bluetooth which doesn't work too well. I sometimes get a decent connection with Foxfi wifi but if I walk around it cuts in and out and then will jump on the first crappy connection it sees or just search for another open connection. Foxfi shows connected on my phone but not on the tablet when it drops. Is there a way to keep the connection more stable? I am using a Nexus 7 tablet Jellybean. Thank you for any help. My phone is not rooted. If there is a better way I will root if needed.
