Asus Zenpad 10 Z300 wifi not staying connected

[itmanning]

When I returned from a 2-week holiday last week I found that my Zenpad 10 Z300C had completely powered itself down, and required several attempts to hard reset it. It eventually started up, and went through a lengthy "optimising apps" stage, as if there had been a software update (but there were no other signs that there had been an update). My build number is LRX22G.WW_P023-V4.7.5-20160419044030548_201506300108.

Now it frequently disconnects from my wifi router - it won't stay connected for more than a few minutes at a time. The wifi icon in the notification bar changes to what looks like a small circular arrow (not dissimilar to a recycling icon). If I turn wifi on/off I see an "authentication problem" message next to the router's SSID in wifi settings. The only way I can restore the wifi connection is to turn airplane mode off/on.
Any idea how I might fix this??

1. Try and restart the tablet. Sometimes it is that simple.

2. Update the firmware and any apps that need updating on the tablet.

3. If the problem persists, check your time and date on the tablet to make sure it is correct.

4. Should none of the former work...
a. Clear out the WiFi data on the tablet.
b. Reboot the modem/router.
c. Once the modem/router is fully 'up' again, reboot the tablet and re-input the WiFi data.

5. Now, if you are still having the problem at this point, and you are sure it isn't the modem/router that is the problem. Then you may wish to try a "Hard Reset" of the device. However, I really suggest saving this as a last option (or last before parts repair/replacement).

NOTE: Doing this will clear 'all' the data on your tablet, so it is suggested you not choose this option unless you have to, or aren't worried about losing anything on the device.

Be sure you back up any data you want to keep, to a computer or cloud account, before doing the reset.


To "Hard Reset" the tablet...

1. Make sure that the tablet is actually powered off.

2. Press the "Power" and the "Volume Up" buttons, together, until you see the start-up logo on the screen.

3. Once you can see the logo, release the buttons and allow the device to enter the "System Recovery Mode".

4. Next use "Volume Down" button to get to the "wipe data/factory reset" option When in recovery mode the "Volume Up" and "Volume Down" buttons are how to can navigate and highlight what option you need.

5. Once you have selected the "wipe data/factory reset", press the "Power" button to select that option.

6. On the following screen, repeatedly press the "Volume Down" button until the "Yes - delete all user data" option is what is selected.

7. Then press the "Power" button to hard reset the tablet.

Thanks for your suggestions. So I ended up switching to a different wireless access point and so far the problem hasn't recurred. Fingers crossed....

Terrific. Glad you got it sorted.

I've been having this problem with my Azus P027 Tablet, running Android 7.0. I followed the advice above, which didn't help. But it led me to Settings ... Wifi ... "Gear icon" ... Saved Networks.
I had a whole bunch of old saved networks and I also had two entries for my household router - I deleted them both. Then I was able to connect the wireless.
