I have a few issues since doing this update. Prior to this update my Phantom would get a gps lock within a minute tops. Now it can sometimes take 2or3 min. Also my wifi range is way shorter now but only at distance not altitude. Meaning, if I go straight up I can easily do 400ft but if I go out it will cut off at about 250/300ft and go into failsafe.
The conditions are exactly the same as far as my location. Today is a little overcast is about the only real difference. Just odd that this started after doing the update. The limits are still at the default. Can't remember at the moment but they are set way beyond what I'm getting.
Any ideas? Thanks.
Oh, batteries on the extender, tx, and Phantom were fully charged.

Amos, I think the first boot up after a Vision NAZA firmware upgrade forces a cold start of the GPS & IMU, causing it to take a bit longer to rebuild its lookup tables, plus overcast skies may delay GPS acquisition even further. Once the tables are rebuilt, its next boot up should be quicker like what were normally used to. I've noticed this with every upgrade to the autopilot & Central Board.
Failsafe kicks in when Vision no longer receives a 5.8GHz control signal from your TX/Controller. That your Vision can still receive signal up to 400' overhead but not out to 400' almost suggests your stick antenna is oriented incorrectly; the tip should be pointing at the sky but I'm sure you already know that, so this gets even more interesting.
The two 5.8GHz antennas on the Vision are the little gray wires taped to the inside of its landing gear. They should be undamaged & pointing straight down.
You may want to open the TX/Controller and check the antenna lead & its connection to the transmitter module. Basically you're checking to make sure the cable is solidly connected to the socket on the transmitter module and that the cable isn't pinched or damaged. Almost all of them are glued to the connector to prevent folks from accidentally disconnecting it when opening the case & upgrading firmware. If there's a glob of glue and you don't see and broken or frayed wires, you're lead is probably fine.
If everything so far seems to be in order, your TX/Controller's transmitter may have failed. Mine did, and so have a few others on the board. Unfortunately there's no easy way to check the transmitter without an RF power meter. There are a number of reasons why they fail beyond the scope of this discussion but let's just say QA/QC is not 100%.
Contact DJI Support USA and submit a report citing 400' up OK, 400' out NG and tell them you'd like to send your TX/Controller to the LA Service Center to get it checked. You should get a green light in a few days. If they ask you to ship both Vision & Controller, its up to you but I only shipped them my Controller knowing if they didn't find anything wrong I could ship the Vision later if I had to. Once they receive your controller you'll get an answer in a day or two.
Good luck,
