cannot connect to known Wi-Fi after OTA-11

[Victor gonzalez]

We're receiving many customer cases where after updating to OTA-11 they cannot connect to their known or saved Wi-FI AP's. The most common behaviour is that M10 ask indefinitely for password when it is supoused to be saved previously. I guess this is about network manager that has been updated in OTA-11

What we are asking the customer for:

1º Forget the network through the UI Settings>Wi-Fi and connect to it again as if was the first time.
2º Try to connect another Wi-Fi AP not saved previously
3º Factory data reset(but we haven't recommend it yet)

Please let us know which logs do you need and we'll try to reproduce it with our units.

@pmcgowan, I think we're tracking this one already. do you know the bug number?

[Pat McGowan (pat-mcgowan)]

There is not a matching issue filed yet.

I often see what sounds like this symptom. After a suspend and resume the wifi connect dialog is shown, I simply press cancel, then select the AP from the drop down and it immediately connects.

Status changed to 'Confirmed' because the bug affects multiple users.

I experienced this bug yesterday with VEGETA(OTA-11):

- WLAN SSID: JAZZTEL_0E78
- The WLAN was previously saved in OTA-10.1
- Once in the house, VEGETA did not connect automatically when was in range and it kept asking for password no matter how many times you enter it

From the syslog I can say the workaround provided to some of our users worked fine(at leat for me):

1st Attempt to connect
Jun 7 19:34:45
1st Connection failure
Jun 7 19:35:10

Disable/Enable Wi-Fi
Jun 7 19:36:51/ Jun 7 19:36:52

Connection deleted JAZZTEL_0E78
Jun 7 19:37:17

Then enable/disable flight mode

2nd Attempt
Jun 7 19:37:40

DHCP Resolution and connection
Jun 7 19:37:44 -- Jun 7 19:37:47

Hi @pat-mcgowan!

I tried to cancel the wifi connect dialog and then tap on it again, but it still asked me for password :(

I think I may be seeing a different issue - bug #1560373, trying to reproduce now

I have been experiencing weird wifi issues on my Pro 5. It is not unusual that I it asks me to re-enter my wifi password while in the house. I have also noticed that sometimes I have to pull the indicator menu down and tap my home wifi before it reconnects.

Hi all,

We've got a user that cannot connect to his Wi-Fi AP, we've tried the same steps but is still not able to connect. Here is a resume of the info and test:

- Frieza on OTA-11
- Forget Wi-FI AP
- Reboot both router and tablet
- Enter password again but seems like is still asking for the password
- He did not change the password
- Other devices connect correctly(he has also a Krillin that is working fine with his Wi-FI AP)

Any hints or logs to ask him for?

[Pat McGowan (pat-mcgowan)]

@victor we can get the syslog and compare the failure

from the one you posted in comment #4

which is something I saw on my m10 as well

and when it works

I just updated bug #1593686 ( WPA-PSK limit introduced in OTA11 ) with the root cause which confirms Pete's theory about timeouts.

That said, *if* a user had successfully connected to an AP prior to the update to OTA11. This *shouldn't* have caused issues, as the psk would already have been present in the connection file, and it should've just worked.

If further problems are reported, checking the length of the user's passphrase should be suggested.
