Spontaneous Reboots caused by Wifi? - Samsung Galaxy Tab S7 / S7 Plus Questions & Answer

Hello all...
I´ve got a funny Problem with my brand new S7+5G...
When i´m at home all ist fine. I´ve got a Fritzbox 7530 and all my devices behave well.
But when i´m at work and my tab is using the Wifi there it spontaneous reboots now and then...
It has to be a problem with the Wifi cause if i disable wifi and use 4G (no 5G available at work) everything ist just fine!
Is there some kind of setting i can modify on the Wifi or my tab?
Sorry for my english but i hope i made myself clear...

Seems like i found the solution...
I did a network settings reset (did that several times before) and this time i changed the MAC adress to "tablet MAC"...
Since then: no more reboots...

Mmmmmhhh... seems like the solution was just temporary... Today the tabs reboooted again.
I´m back to cellular...
Any ideas?

problems after upgrading with fantastic b4

hey there!
First of all, a big congrats for b4. It's made my Qtek S200 one of the most complete phones I've ever handled. Using for a while now, I've decided to ask you guys about two problems I've had. First, my phone has stopped vibrating. I know it's not a physical problem since I downgraded to my original rom and the vibration started working again. But once I upgraded to fantastic b4, no vibration.
2nd problem is I'm having trouble activating both bluetooth and wifi. For bluetooth, the only way I can get it to activate is by clicking the bluetooth at the bottom right of the today screen, and that just after I've done a soft reset. There's no way I can get it to activate using the Comm Manager screen. Now for wifi, I've the same problem. I can't get it to activate even after doing a soft reset.
Anybody has any ideas for my problems? Thanks for letting me know.
p.s. I've installed the PCMKeyboard which is an emulation of the iphone keyboard and now my ppc is uniquely thumb dependant!
I installed gulum's Touch v6 and now both the bluetooth and wifi are working correctly. However still nothing for the vibration...

[Q - Solved] No Wifi Detection!! Please Help!

EDIT: Tried today and seems to be working now. Weird, just works when it feels like it.
Has anyone had the same problem and managed to fix it? Only thing i can think of doing is a master reset which means losing all my programs etc. I restored a backup with SPB to no success. Whenever I try to connect to my home router which has no encryption, it says 'unavailable' and no network is detected. Also, if I'm out, it detects networks which are security enabled even when they are arent! Thinking of selling, but can't until I get this problem resolved. Any help would be most appreciated.
P.S. It was working last night, but today it's decided not to and the problem is not the router as I tried with another phone.
Hi, just wanted to say I fixed the problem... I changed the channel on my router to 6 and restarted it, then my TG01 picked up the signal and can connect so incase anyone has the same problem, try this.
Cheers!

[Q] Time update problem after Rom update

hey there guys,
i updated the rom of my HD2 with the latest version available on Htc site. the problem now is that time changes by itself and though i have checked "get time from the internet " it can`t update corectly
gmt+2 is set , i put the time corect and after some time it goes by itself one hour or 2 in advance, sometimes even more.....don`t know where the problem is.....
I connect it to the internet and though it sees my location good it can`t get and keep the right hour!

Try search next time. There are several discussions about this. This works for me.
Go to Settings\ Menu\ All settings\ Personal\ Phone\ Gsm/umts Services\
Time Synchronisation\ Then press Get Settings, Unselect the box and press ok!
seems to be working for me.

I have hardreseted but the problem is still there.
I have also tried the solution above without success.

Xperia Sola Wifi Problem

Hello guys
My Sony Xperia Sola was perfect until i updated to ICS. ICS is very fast,smooth and beautiful software but since then i am experiencing a wifi problem. My wifi get frozen and stuck to connected. I can't disconnect it. The only way to disconnect it is to switch of the phone. I foundnd a "solution" to this problem. Problem seems to disappear if you make a factory reset of the phone. But after a week it comes again. It's so annoying. My "solution" is to make back up-and restore once a week to avoid the problem. If i didn't do the factory reset problem comes again. Is there any solution to this issue? I heard a lot who have this problem after updated to ICS(problems appears and to xperia u)
Thank you

Please post Q&A in the appropriate section next time

Any solution guys??
Change the wireless interface on your router to be 802.11 b/g only - not b/g/n
that helped me!!
sola wifi prob
i have the same problem, i restart, format, anything, but the wifi still doesn't turns on.
even at the first startup screen, i clicked connect only using wifi, than i select network, after that it just stuck there and the wifi will not turn on forever...
i had formatted my phone at least 3times today...
can any1 tell me y???
and how to fix it???

flash ur device using flash tool, it can be found in the forum too, and it shall be fine after that, just dont know that how long it can last...
same issue
I completely understand the original post.
I don't want to bother with any routers, 'cause it had been working fine before. It mustn't be a question of router settings.
Some software upgrade of the phone might have caused this problem and I'm still waiting for any reply from Sony on this. If they don't do anything in a month I'm gonna push this **** device to a repair station, though I don't feel much desire for the mess that comes with this procedure.
Generally the phone is very slow (and sometimes it opens the phonebook instead of call list, sometimes it take 10 secs, etc.), I wanna get rid of it but I have to wait till the end of my telephony contract's period.

[Q] Network data and WIFI disconnect when the screen goes into sleep ?!

so i got S3 a week ago . i had many friends having it i even helped them to update it many times .it came preloaded with 4.0.4 ... but i directly updated it to 4.1.2 using odin ...and now runing on XXEMB1
done factory reset ...and rooted it ...after a while of use i noticed that the network data connection and the wifi get disconnected every time phone went to sleep .
...so naturally ...i tried another factory reset ..but no joy so i did another flash using odin without rooting this time
and yet wifi problem remained ..but could stay connected to data after couple of days went back to losing both if it goes to sleep
i have tried the *#0011# fix but nothing changed
in wifi settings ,,,it is set to always stay on during stay ....
i would appreciate if some one can point me to the right direction ...since replacing the handset is no option :/
is it a faulty handset ...cuz i used the same firmware over my fiancee's phone and it is fine ...same for some of my friends ...so i think it is about this phone in particular ....any help plz !
i guess this is mark it as either : stupid question , something new ,, or just with no fix :/
Dunno if this helps, but try juice defender, it has a lot of options to configure, and as i remember, it has one to keep conectivity on while sleep

Hi Infernal88,
by replying the post in such a manner doesn't make you not stupid.
Hi All,
I am also encountering same issues as TS. Is this a rom issue? or hardware issue?
Thanks
