wifi hotspot misbehaving (NOT the same as the recent problem appearing only in 5.0)

[toothpaste]

here is a link to a video i took of the behavior. https://www.youtube.com/watch?v=pmrhhNz7AFo

 

after some random time, maybe 10 minutes maybe two hours, any devices connected to the phone hotspot will lose the connection and no device can see the hotspot anymore, even though the phone shows the hotspot as enabled

 

this is the dmesg output when this happens:

 

<3>[  821.076116] wlan: [5345:E :PE ] limDeleteStaContext: 118:  Deleting station: staId = 3, reasonCode = 2
<3>[  821.085966] wlan: [5345:E :SME] csrRoamCheckForLinkStatusChange: 9530: DISASSOCIATION Indication from MAC for session 0
<3>[  821.086099] wlan: [5345:E :SME] csrRoamCheckForLinkStatusChange: 9533: DISASSOCIATION from peer =00:eb:2d:fa:f6:64  reason = 505 status = 505
<3>[  821.091929] wlan: [5345:E :PE ] __limProcessSmeDisassocCnf: 2744: received DISASSOC_CNF for a STA that does not have context, addr= 00:eb:2d:fa:f6:64"

 

 

 sometimes, disabling and reenabling the access point on the phone resumes hotspot functionality (other devices see the hotspot and connect to it)

other times, what happens is what you see in the video

it happens in all versions i have tried on the phone, 4.4 and 5.0

 bluetooth disabled, wifi scanning when wifi off disabled, background data queueing disabled

i have more info

since the logfile is too large for this message board

here is the link to a pastebin of it: raw text, pastebin site text

please put it to good use

Sorry to hear that you have issues with using hotspot.

It's not something an issue i'm familiar with but i've forwarded your logs internally to see if i can find more information.

[toothpaste]

it is very important to give them ALL the logs i have put here and on pastebin and tell them to contact me for any more info

[toothpaste]

@Rickard update, please. What did the programmers say? Did they see the logs?

[Rickard]

I don't have any response yet i'm afraid.

@Rickard here is a more detailed error dump, please use it to your best knowledge

Could you please let me know which build number you have, which operator you're using and the customization version you have in your phone? To check customization version, dial *#*#7378423#*#* and select Service info -> Software info.

my operator is wind greece ("WIND GR")

1278-9222-R1D

however: these are not what i was using one month ago.

back then i was using the first ever public official release 5.0 for the z ultra, i think it was nordic

don't think it matters much, i'm positive whatever caused the problem still exists
