my problem is resolved with out doing a restore. I did further research and decided to try it. Did a reset of the network settings on the ipad, shut it down, rebooted my wifi router, restarted the ipad and then reconnected it to the wifi network. Three days later and no more dropped wifi.

SInce I had the factory reset done, it's been as good as new with no WiFi-issues or slow connections neither at home or on the mobile connection (that I'm using now.)

Finally I gave up and bought a new router. And my WiFi issue is resolved.
MagicStick: Apr 26, 2015, at 1:11 PM (paraphrasing): yesterday morning I went to a store and bought a ASUS DSL-N55U router. I am extremely happy I have a working network again. (note: this comment, along with what was added in, appears to have been deleted from the board.)

(Paraphrasing) ...my main issue is maintaining a stable connection with router in order to maintain a stable VOIP connection. I decided to take them up on a $25 new Asus Router RT AC68U. Its been a week and have had only one dropped connection since the new ios 8.3 update. Not yet sure still running tests, but on the 5Ghz frequency my connection is stable

I had the same problem on the devices I updated through wifi, a restore as new, then restore of my iCloud back up fixed the issue.

"I have had this problem too, this has sucked up my time for the whole day with resets, reboots changing settings everywhere I can access - then finally I simply turned on my airplane mode and "WIFI" started!!"
