no wifi channel 12/13?

Hi,
I have been using channel 13 on my wifi and winphone for almost a year i just updated to os 7740 bootloader 5.1 on my htc pro 7 and noticed after about 2hours of trial and error that it no longer picks up channels 12 or 13.. is this normal behaviour as it use to pick it up previously. infact it was picking it up after the update untill i enabled internet sharing after i disable it and the wifi restored my network disappeared..
thanks

Hey,
I think I've the same issue like you with my HTC HD7. If I wanna connect to my WLAN (channel 13) my phone wont connect. After change to "1-11" everything is fine.
I've no idea why... :-(

I've done abit of research on other devices and im seems these channels are illegal in the USA so I think that is why we can't use them what I dont understand is why it worked fine on everything below the 7740 update and why it dosnt realise where not in the USA. I've ended up switching to channel 1..

[Q] OPO won't receive calls or SMS when on wifi

Having some issues with receiving calls and SMS on my OPO when connected to my home wifi router, I have searched forums and official OPO forums bit have had no luck finding a solution.
Im from the UK and use virgin mobile (uses the EE network), router is the virgin superhub if that makes a difference
Problem seems to have been happening since I got the phone (begining of Dec 14) but I only became aware of it around new year, girlfriend has an OPO also and does NOT have this issues.
Phone is the global model running stock cyanogen 44, android version 4.4.4
Any help would be appreciated, struggling with this one
Thanks

This has been an off and on again issue for many devices since 4.3 was released. I did a google search and Nexus 5 was plagued by this. There's a long thread on the google support forum, with several OPO posts. The thread is more than a year old, and no root cause has yet been discovered. There appears to be no rhyme nor reason regarding who gets it and who doesn't. I have had this happen intermittently, and a reboot usually solves it. For those who suffer this chronically, the only work around seems to be to keep the phone on 3G preferred. Don't let it connect to LTE.

Yea I found some people talking about the issue on other devices, seems really weird, and yea I did change the preferred network setting to 3g (was previously set as 4g which my network doesn't provide me with) and it worked for a while, however seemed to start again recently, will search for those threads and have a read, thanks for the help
Any other info from people with this issue would be helpful too,
Is it possible that changing my routers broadcast channel would make a difference, could it interfere with the radio?
Thanks again

Still having this issue, yesterday I reflashed stock cyanogen 44 via fastboot method and problem is even worse now, the issue seemed to be every now and again but seems to happen every time now
No longer receiving calls when connected to 3g and WiFi either, only workaround seems to be if I switch to 2g mobile services and I'm still able to receive calls on WiFi
Is there an easy way to make my phone auto switch to 2g on WiFi (closest iv found is disabling mobile data on WiFi)
Thanks, hope anyone has some more info on this
Edit; found a workaround by using g cyanogen profiles to downgrade to 2g on my home networks, but still looking for info on a perm solution, thanks

I´m having the same issue with Wifi turn on, I cannot make or receive calls.
Let me know if you find a solution.

Intermitent issues receiving calls on OnePlus One when in WiFi
I'm also having this intermittent (Not always!) problem of not receiving calls in my OnePlus One when connected to WiFi. This started to happen after a regular upgrade to Android 5.0.2 (Cyanogen OS 12.0-YNG1TAS17L).
I found the solution in forums.oneplus.net. Just search for: virgin-mobile-uk-no-incoming-calls-with-wi-fi-enabled-and-3g-lte in Google and you will find the link. Go to page 3 on this posting.
The issue is related to the fact that calls fail while in WiFi and LTE. Create at least two System Profiles (Settings -> System Profiles). One to change the "Preferred network type" to 2G when connected to any of your WiFI networks, and another that changes the "Preferred network type" to 2G/3G/LTE when disconnecting from any of your WiFI networks.

Note Pro 12.2 Update After Canceling Data Plan

I recently picked my note pro 12.2 back up after some time sitting unused. I finally got around to getting the flickering screen fixed and want to get back into using the tablet more often. The issue I'm having now is updating to a more recent firmware. I'm unable to even check if I have the most recent firmware because I don't have a Verizon data plan or SIM anymore (long time coming) and it doesn't seem to want to update without that connection. Does anyone have a way to go about updating the tablet manually?
Also, is there anyway that I can flash the Wifi firmware on to the tablet so it ignores the fact that I have the data connectivity and acts like a wifi model? I've rooted multiple phones in the past, and as long as I have a good set of instructions I can do quite a bit but I'm still looking for an answer to this question.
Thank you.

you can use samsung smartswitch for PC: http://www.samsung.com/us/support/owners/app/smart-switch
to get the latest firmware.
just note if you need root, the new versions of 5.1.1 are not yet rootable.
unfortunately this device has a locked bootloader so flashing a non Verizon firmware to get wifi only is not possible currently.
I have noticed if you have a sim card installed with no service (I have a Tmobile sim with no service currently) it drains the battery pretty bad as it keeps looking for service, connecting and then disconnecting.
I turned off mobile data in the settings which fixed that for me.

Thanks for the info. I'll take a look at updating it to the latest firmware. I don't need root, was going to do it if we could flash the wifi firmware.

mobile data.

Hi. Im in uk and have f2 pro 5g. I have in settings set prefer network to 5g. 5g is not available where i am at all. My problem is my mobile data (working fine with lots of other phones so not signal related) sometimes just stops working.
I have set to prefer to 4g and still the same. I have updated my apn settings ( not much to change) and done factory reset. I have looked on the dial *#*#4636#*#* and i have phone info 1 and phone info 2. I go to set network type and have a list. Whenever i chose one after reboot it changes back to unknown. (Please see pics)
Any ideas???
Thanks guys.

Hello mate, phenomenally I've just received the phone yesterday. Beautiful phone. However I've come to notice the same issue. Changing over prefer lte or 5g does nothing. The only real fix is switching off data and switching it back on. Never had this issue with all my previous phones, including realme, oneplus and Huawei. It's most probably a software fault. But it's making me want to return it.
Im noticing the following, switching WiFi off when outside doesn't cause the issue but need further testing to confirm.

I read about that bug but I can not confirm it. If you turn on 5G you can only use 1 sim card but 5G is anyways almost useles on this device (only N77/N78)

3 uk is on N78

Agree, I live in Puerto Rico and it doesn't even have T-Mobiles band 66 LTE. Incredible that a phone powered by a SD 865 lack of all of these. Software updates are super bad, I haven't got 1 single update and 5G on this phone is useless.

Tmobile Note 20 Ultra major issues after update

My wife and I both have the note 20 ultra through tmobile since they launched. We love the phones. On 2-26-21, we both got the OTA Feb 1st security update and things have been horrible since. It started with off and on messages wouldn't send. And weird messages about SMS sent via server. Then starting on Tuesday 3-1, we would lose service all together for hours while the other phone showed service. I've troubleshooted it so far with:
1) Turning on and off mobile data and airplane mode
2) tried turning on and off wifi calling
3) restarted phone
4) soft reboot
5) reset mobile network settings
6) factory reset phone (this worked best for about 20 hours but now is back to doing it again)
Any ideas how to fix this? I'm positive it was the update that caused it as we both having the same issues on our phones after the updates.
Update: tonight I went into network settings and turned off the 5g autoconnect and seem to be keeping service now. Question is, how do I get 5g back? If I turn 5g on, network operators just shows searching and it won't let me pick one myself.
The security update we both got is Feb 1st, 2021 ...N986USQU1DUB5. Any way to downgrade to the Jan 1st one so our phones work again? Anything tmobile can do?
Any ideas will be appreciated, thanks guys.

T-mobile in my area send to be updating the 5g towers. I wouldn't be able to use it for a while. But once it was working again the speeds were way faster. Mine only took a few hours though. Check again other days. And also my brother has issues with texts not sending correctly when on 5g until he got the new sim card. Check if you have the new 5g sim card that says r15 on it

Turn off autoupdates and wait at least a couple weeks to load them.
Let someone else be the Guinea pigs...

I checked and we both have the r15. Issue seems to not occur as much now so maybe they were working on the towers and was just a coincidence it lined up with the update?
