[Q] Problems with refresh/switching of wi-fi access points - Xperia Z1 Compact Q&A, Help & Troubleshooting

I've started noticing weird issues with wifi recently - when I move from one wifi access point to another, wifi list is not refreshed (says "Connected" to AP that is way out of reach although wifi icon in status bar is inactive), and this is not happening even when I tap "Scan" manually. To connect to other AP I have to turn wifi off, wait few seconds, then turn it on (both AP's have saved passwords, reconnect happens automatically).
What's interesting, wifi access points lookup works fine in general and I continue seeing "Wifi access point available" notifications from time to time.
Confirmed this problem on firmware v.14.3.A.0.757 (4.4.2), upgrade to 761 did not fix anything. This is not very likely a setting issue, tried playing with "Scanning always available", "Wi-Fi optimization" settings, etc. Not 100% sure stock firmware had this issue (14.2.А.1.114 (4.3)), although if there is some easy way to downgrade I might go with it.
Does anyone encountered the same issue? What can be done to diagnose this issue?

Data connection problem when coming back from Airplan mode...

I've stumbled on a strange issue.
If I switch the Desire to the Airplan mode when the Data connection is off (I use the appropriate HTC Data connection widget to do this), when I switch back to Airplan mode off, the phone is no more able to restore the data connection.
The only workaround found is to restart the phone.
Has anyone got the same experience?
Two questions.
1. When you say you switched off data connection, are you talking about syncing, wifi, mobile network, ... etc?
2. Why do you want to switch off data connection and turn on Airplane Mode? Doesn't Airplane Mode cater for shutting down all wireless?
1. I'm talking only about the "Data connection" option on "Wireless and networks" menu, that is switchable via a special HTC widget. Switching this option off, the phone is no more able to access to the GPRS provider. I often keep this option off to save battery life. I turn Data connection on, if I need to sync and access to Internet.
2. This is not the matter, just it happens. Eg. When I go to sleep, I turn the Airplane mode on, doesn't matter if the Data connection is on or off (it is possible that it is on) in order to avoid any disturbs (calls, sms, etc.).
I just wonder if this issue is a true bug of the phone:
1. Switch off Data connection
2. Switch on Airplane mode
3. Switch off Airlplane mode
4. Try to activate Data connection (for me it seems it's not possible without a reboot)
Had a similar problem which I wrote to HTC about: after the phone has been data connected via wifi and I leave the wifi network it often will not connect to data via mobile network (GPRS/3G), giving the message "connection failed" if I try to manually connect in the "mobile networks" section of the "wireless & networks" settings page.
It seems to have fixed itself now, and I think it's because I've since ticked the option to "enable always-on mobile data", which I had turned off to save battery. Give it a try.

Thanks yurikg, but on my phone the "enable always-on mobile data" option is checked, anche there is no mobile network connection problem coming back from a Wifi connection.
The problem I shown is probably caused coming back from Airplane mode.
The other possibility is Juicedefender which apparently is known to cause problems recovering a mobile data connection (recent update may have fixed this):

I've not juicedefender on my Desire...
I've in plan to do some other tests...
I have a problem with my Desire reconnecting to a mobile data connection too, but not when I come out of 'plane mode, its when I leave a Wifi covered area. It could be the same problem, triggered by anything that disables and then reactivates the data connection?
I have no solution yet, and I have contacted HTC support about it (still no reply). There is some discussion here:
http://forum.xda-developers.com/showthread.php?t=656192
I seem to be having this problem too when coming off WiFi connection, unfortunately restarting the phone has not righted the issue...
I'm also having this problem with the connections. Fine on the wifi at work and at home but not switching over to the mobile network. Apart from that the phone seems awesome! Soooooo much better and more fun than the HD2.
OK, my phone appears to have no network connection whatsoever in fact...
Have the same problem as well. Coming from Wifi and to mobile network only - I do not get any data coverage. This is for the Desire and I had the same problem with Legend.
I hope this will be worked out ASAP.
Well, my problems all sorted. Turns out I had to manually input the APN for internet, took me by surprise since no phone I've owned since 2006 has needed that...
Just had to put in the settings manually too. Seems there is an issue with some of them. Would put a link here but as i'm a newbie not allowed Just google vodafone apn settings for htc desire and hey presto
Same problem here, my Hero had it too. I found it did work when you switch to gsm only and back to 3g/gsm... Would love to hear good solutions.
Im also having the same problem.
If i try switching my connection from wifi to mobile data, my mobile data connection fails to work. A power cycle fixes the issue but if i try switching connections again, the problem returns.
Can I suggest to anyone still having problems getting their phone to switch to mobile data when leaving Wifi to view the following bug report on Google Code and to star it to help raise the priority with Google:

4.3 Wi-Fi bug?

Anyone else notice Wi-Fi randomly deciding to turn off/not connect to automatic networks, like your home or office?
I notice that sometimes I'll pick up my phone and go to use the VPN and it will say I can't connect because I'm not connected to the Internet. Or I'll get an email in Gmail while using my laptop and wonder why my phone didn't beep just then and notify me. I then look in the to corner and see it isn't connected to my network, nor making an attempt to. The Wi-Fi signal symbol just isn't there. The Wi-Fi quick settings button is highlighted meaning Wi-Fi is in fact enabled, but it isn't connected to it for some reason. The second I go look at the network list -- and it does see all the networks so I know for sure it is enabled and scanning -- it instantly tries to connect and does so perfectly fine.
I thought it was just a bad signal once or a router issue, but it has happened several times now since updating to 4.3. This has never happened before.
It's just like it randomly decides not to try and connect to the network unless I open up the network list. It's random as far as I can tell. It's usually fine, but it has happened on more than one occasion now since upgrading to 4.3.
Any ideas? I haven't changed any settings since 4.3. I thought it might be battery/idle related, but once I get it to connect again, it stays connected no matter what the status of the battery or how long it's idle. This makes me think it's probably a bug.

[Q] Wi-Fi Just Decided To Stop Working (Switches Off After 30 Seconds Or So) CM7

Hi All,
I am still lumbering on with an old HTC Desire running CM 7.07282011-Nightly and have had no real issues up until a couple of days ago.
Whilst in France (not that that make a lot of difference) the Wi-Fi access stopped working and the phone stopped being able to see any Wi-Fi networks. Basically, it switches itself off after around 30 seconds and cannot pick up any networks. In addiiton, the WiFi MAC address shows as unavailable although teathering via a WiFi hotspot works fine. I was switch between teather and normal Wi-Fi when the problem occurred.
If I go into Settings --> Wireless and Networks -->WiFi setting, then switch on the Wi-Fi, I get the "Turning on" message but then a Sorry warning saying "Application Settings (in process com.andriod.settings is not responding" and I can either "force a close" or "wait". If I wait, the Wi-Fi will simply switches itself off after about 30 seconds.
I did read in another post that this might be to do with the Wi-Fi sleep status but I tried all 3 options (from the menu in the Wi-Fi setting page) but that didn't do anything.
The issue appears to be that that phone has lost the Wi-Fi adaptors MAC address (says unavailable). However, I can still use Wireless Tethering and connect to to the phones WiFi hotspot. I think something has go screwy with the Wi-Fi tethering and Wi-Fi access (as I was switching between both when on my travels), but I need some help in trying to fix it.
Any Help Welcome
Chris
I tried updating to cm-7-20130301-NIGHTLY-bravo (whuch was the last release version), but still no joy.
Any help welcome
Well, after trying pretty much everything, I had to run a factory reset on the phone. Finally, my Wi-Fi is working again. Of course I now have the ball aching job of setting the phone up and re-installing all my apps again. Google restore is pretty rubbish
Looks like there must have been a config setting that got screwed somewhere. I did take a backup of the ROM and if anyone knows where this might be resolved, I wouldn't mind restoring.

[Q] WiFi Problem

Out of the blue, my WiFi stopped working. I know occasionally this happens and is usually fixed by simply turning WiFi off then on again our by unplugging the router for about ten seconds, but neither of these methods is working this time. This is different, I'm stumped. (By the way I have the SM-P600)
So, the error message I'm getting is, "failed to obtain IP address", then if I click, "RETRY" I get an error message that says, "Network disabled because internet connection is too slow." Which doesn't make sense because all my other devices on my WiFi network have no problems connecting and have no speed issues.
Really, really frustrating. Any help would really be appreciated! Thanks!
The same problems occurs frequently with my tab P-601.
But I have to restart the tab and it works fine. I have to use mobile data for internet connection instead of wifi.
I appreciate any help.
Anybody else have this happen?
I haven't had this problem on my P600, but have had something like it happen on other devices. I think the issue is that Android will remember and avoid WiFi APs with a poor signal. When I am on the fringe of my home WiFi the signal is weak and my network gets blacklisted. To clear the blacklisting I have to force the device to forget the network, the connect again as a new network.
Couldn't detect WIFI
I updated the Android 4.4.2 and since then my tablet couldn't find my WIFI.
My phone and my computer found the network normally but my tablet just showed some of my neihbors' networks. I tried to restart the tablet and reset the router but didn't help.
Now I tried changing he router's settings through my computer and set the frequency to a higher value and now my tablet finds and connects to the WIFI normally!

Note 5 Wi-fi Rapidly Switching On And Off

Firmware: 6.0.1
Model: SM-N920A
UPDATE: Problem solved. Turns out it's an issue with the WIFI scanning in LOCATION, not in the wifi settings. While I still think this is an issue with the firmware, at least there's a way to get it to stop freaking out until they get it fixed.
Whenever I turn on the Wifi, it will often begin a cycle of rapidly turning off and back on again. If you watch the switch that indicates 'on' and 'off', it's constantly fluctuating between the two. -Immediately- after the switch shows it's turned on, the text just below the switch says "turning off.." and it turns off, immediately afterward turning back on, and the process repeats constantly until the phone dies.
Something is either forcing it to turn off, or forcing it to turn on. I've tried adjusting the settings for my third-party texting app (Textra), and even after disabling the entire app and using the stock one, the issue persisted.
I've tried restarting, I've tried clearing the cache via the bootloader.
I've exhausted the entire suite of options in settings for anything Wifi related, no configuration of settings has resolved the issue, including turning off wifi scanning.
I've tried entering the combination of "#", "*", and 0's and 1's (can't remember it off the top of my head) to access the wifi settings to turn off the power saving, but my phone under the listed model and firmware showed no such option.
The problem persists in any location, so I know it's not anything to do with the network I'm trying to connect to.
The only way I've gotten it to stop is going to the wifi settings menu, and rapidly tapping the switch while it constantly goes back and forth. I've managed to get it to stay in the "on" position, but that's the closest thing to a fix I've been able to find.
I've combed through many threads in the AT&T Note 5 troubleshooting topic, and can hardly find anything that describes this particular issue, only with wifi "not staying connected" or other obscure descriptions that upon further inspection were -not- the issue I'm having here.
Were it up to me I would root the thing and put stock Nougat on there and be done with it. But alas, AT&T has removed that option.
I am willing to do a factory reset, but I'd like to know if anyone else has had this issue and if there is any other way to solve it, so I can avoid it in the future.
Settings > wifi > more (top right corner) > advanced > always allow scanning - set to 'off'
Like I said, I've exhausted all possible options in the menus relating to wifi.
This is what I see when I go into the "Advanced" settings in Wifi.
Network Notification (on or off)
Hotspot 2.0 (on or off)
Keep wifi on during sleep (never)
Auto connect to AT&T wifi (on or off)
Install network certificates
MAC address
IP address
That's all there is. I just factory reset my phone, restored it, and the problem in the OP persists.
I rebooted it in safe mode, and the problem still persists. At this point, it looks like it's an issue with the individual handset, unless there's anything I've missed. This is beyond frustrating.
Sorry but can you explain to me how you stop this from happening?
Mine going crazy from time to time, drives me nuts, and i can't stop it.
Btw this doesn't exist on my AT&T Note 5 --> Settings > wifi > more (top right corner) > advanced > always allow scanning - set to 'off'
Kill AT&T Wifi Direct and AT&T Hot Spots.. Remove them as System Apps also.. You should get a message that it is replacing it with the stock version somewhere along this path then your wifi will work flawlessly again even with 5GHz, go figure I guess Google does a better job at WiFi.'
Edit: (sloppy instructions)
DEVICE|APPLICATION MANAGER
"MORE" top right corner
CHANGE SYSTEM SETTINGS
<disable AT&T smart WiFi and anything else that is AT&T or Samsung, including theme nonsense if you want)
Now remove it from Apps....
DEVICE|APPLICATION MANAGER
Force Stop AT&T Smart Wifi. Disable AT&T Smart WiFI.. (Select Storage in same screeen, restrict background data.. Remove permissions)
I realize some of my steps are redundant but AT&T will update stuff then turn those apps back on somehow.. But not if you gut it like I described above
