[Q] samsung galaxy mini wifi issue

hey guys .
I bought a Samsung galaxy mini ( gt-s5570 ) ,its good except the WiFi .
It can work with my home network for only one time ,if i try to connect again it won't allow me .
I've tried (Nokia N81-Nokia N82-Nokia N8- Samsung Star- Samsung Star 2- Samsung galaxy SII- Samsung Note- Apple Iphone4s) and all of these devices works perfectly with my router ,so i think its the phone not the router .
the router is a Linksys WAG54G2 with latest firmware update version : V1.00.19 ,I've tried all type of security and i even disabled it without any luck .
I've been searching Google for over a month now without any success but I've noticed that this problem happens with many other handsets .
to fix it i have only two options :
1- restart the router ( which is inconvenient ) .
2- factory reset the phone ( can't live with an empty phone 4ever ) .
I tried everything on phone settings and on router settings with no success at all ,I even tried apps from android market to fix WiFi but it didn't work .
any help will be appreciated ,thanks guys.
Here is some pics stating the problem

any help will be appreciated guys

there must be some hope !!!

does anyone know if it is a problem with hardware or software

I've been searching all over the internet for about 4 months now and tried all suggested work around but no luck at all ,how come such a perfect OS like android has such a stupid bug and its not only on Samsung mini its on many other handsets .How can't Google get a permanent fix for this problem and why everyone around the world is so quiet about this problem just because android is so good to be criticized .I was convinced that android is the best OS but now i don't know anymore .

i won't give up
and i'll wait for a solution to the most stupid bug on the most so called successful mobile OS of this time

Unfortunately i didn't find any solution. But i found out that this problem is only on the stupid android so if the WiFi usage is very important to you i'd advise you to switch to another OS.

Thanks for your reply.
It is just on galaxy mini.
I use the same wifi on note 2 and galaxy S advanced.
There should be somthing wrong in driver or device settings.

I didn't mean all android handsets have this problem, but what i meant is that this exact problem only appears on some android handsets. I totally agree with you that it must be a driver issue but as long as i've searched the websites, only android os handsets suffer from this driver issue. You can search google and you will be amazed how many android users searching for a fix for this problem.

I already stated that i can fix it by restarting my router but that's not a solution especially when i have to do it every 2 hours or so.

I had this same problem with my Mini. It's a kernel problem. It solved when I upgraded to Gingerbread through Kies.

Even after upgrading to gingerbread the problem still exist unfortunately. The most annoying thing with this problem is that its not under warranty. I've sent my device to samsung branch in my city two times and their response was "The WiFi is working just fine". I don't care what problems appear in the product as long as the manufacturer covers them under warranty.

Do you have Dlink router?
Maybe it is a router issue, as my wife's Galaxy S Advance has the problem with the same Wifi. It never had such a problem with other routers.
(I have not tested thr mini with the other routers yet.)

[Q] Wifi Channel 13? Can't use it.

I can't seem to see my Wi-Fi AP (channel 13) on my new Nexus 5. It was set up as English UK, so shouldn't have any problem accessing channels 12 and 13.
This is the display in WiFi Analyser on my Galaxy Nexus:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

}
You can see why I picked channel 13. And this is the same location with the Nexus 5:
Have I missed something? I can't find anything in the wifi settings regarding a region setting. Any help appreciated.

When multiple access points (or other WiFi devices) are on the same channel, they notice each other and coordinate to not transmit at the same time. This is to avoid interference with each other. If two devices transmit at the same time, generally both packets are lost and both get transmitted.
Now, when you put them on overlapping but different channels, they often do not coordinate. But still, when to transmit at the same time, the packets are lost. Happens a lot more without coordination, though.
There is a four-channel setup which doesn't overlap, or at least the overlap is small enough, but everyone would need to switch to it...
IOW, you'd probably get better performance on 6 or 11. And your neighbors would too, were you to switch. A win for everyone. Do some speed and latency (ping) tests to be sure.
Or move to the 5 GHz frequencies, which are less crowded and better blocked by walls.

Thanks for the input. I appreciate what you are saying and that may solve the problem from the other direction but it doesn't explain what I'm seeing.
Has anyone else seen this odd behaviour with their Nexus 5?

If I remember right the nexus 4 didn't recognise channel 13 either Max was channel 12 unless on 5Ghz.

Thanks for the info.
A friend's Windows 8 tablet had the same issue a while back, and at the time I remember thinking, "That's a bit crap", and wondering why it would not function to spec. I wrote it off as a Microsoft-ism. Shame to see that sort of approach wander over to Google and the Nexus line of products.

Hi - exactly the same for me. My Nexus 5 does not see channel 13 at all - my Nexus 4 (and 7 for that matter) sees it fine!
Both set up English UK - but the Nexus 5 just will not recognise channel 13 at all... Weird.

It is likely by design and I would not be surprised if the updates for the N7 and other devices start blocking it out. Thanks to US FCC regulations, overseas might not be able to use them.

I'm having the same issue. I had my AP setup on channel 13. I had no issues using it on my laptops, SGS III, SGS 4, Samsung Note 10.1 but when I fired up my Nexus 5 I did not see my network.
After few days figuring out why only this one network is not visible I finally changed the channel to 11 and it is working fine. But it is not solution so I kept digging and I have found out that is going on. At least in my situation.
Channels 12 and 13 are allowed to be used in Europe and Japan only. I'm in Poland, phone is from German distribution so I thought that it should be not as issue. Apparently phone distribution/origin is not the case.
I was testing it without the SIM card since I was planning to set it up completely before moving from my SGS3 to it. Once SIM card has been inserted phone recognized it is in Europe and channel 13 became available! Pretty weird for me but looks like it is working that way...

Great post artiwal. After I put the sim in, channel 13 networks suddenly become available. Thank you!

[Q] OPO flashed on CM11s - Mobile Data issues

[/ATTACH]Hello my friends,
I really need your help now. Since the Oneplus One is so new there are only few people having experience with the smartphone and it's Problems. I searched the whole Internet but dit not find anyone with the OPO who has the same Problem as me..
My OPO is the chinese Version and i flashed it without PC on CM11s.
But I found that my Smartphone has got no mobile Internet and also I am not able to call someone.
After I saw this I flashed the phone two more times, but with my PC and fastboot. I used the Images here: https: //cyngn.com /products /oneplusone/
Once I flashed my phone with PC and fastboot I got mobile data sometimes for about one or two minutes, after that it breaks down.
My APN's are the same with my Provider.
I tried to solve this Problem for the whole weekend, I now even consider selling the phone again..
It would be really really nice if someone is able to help me!
Best regards,
4p9xD

hi
I had a similar problem. I had a sim card trimmed with scissors and was too loose.
I replaced the card with a new one.
A problem, however, remained. Sometimes I can not call, sometimes not the Internet. It looks like something crashed and helps only restart.
You tried to upload the "modem chack"?

I have the same problem. I hope it is not something with hardware.

I don't know... could you check production date on the box?

Sounds like a kernel issue, did you flash the right one?

What do you exactly mean saying rightone?

If you have a Chinese version then you need a kernel made for your phone.

I instaled cm11s in fastboot according to instruction on this site. Can you show us which kernel we must use?

I'm exactly the same. I installed by the recovery and than two times through fastboot. ROM from the official site.

Another one here! I have exactly the same thread starter problem, 1 min after turn on the phone I cant call anymore or sending messages...
Right kernel? Can someone explaine? I have tryed to flash 3 version of CM11 and return back to ColorOS, the problem is not solved :|

the problem occurs on coloros? I can call but not always. The issue is when switching between frequencies - from internet 4G to gsm...

Is possible that this is a hardware problem?

Bump!
Please help us boys, I have tried everything, I really dunno what to do

same problem
I'm having the same problem, the phone was working just fine when i first used it on ColorOs with voice calls working on 4g. however, as soon as I flashed CM11 it stopped working and I can only use 2g to make phone calls even though 4g internet works fine. I have flashed ColorOs but a rooted one, CM11 and other roms the problem is still there. If some one can find a solution for us I would be grateful.

if someone tried to flash modem hack... I've seen 3 versions...

the problem still occurs?

I have the same issue, after flashing to CM11s, its like the cell network is sick, turn on for a while, then off. when the phone is in the pocket (sleep) totally not network, and people cannot call in.
I flash back to Colour OS, more stable and 4G is working fine.

If you didn't flash a new radio, then its probably a kernel issue.

Sorry where can i find the new radio for OPO...?

hi
I could not find radio.img for the OPO. I found the network settings through the code: *#*#4636#*#* and changed the settings.
was: TD-SCDMA, WCDMA and LTE
new: LTE / WCDMA
and see if it is ok...

9.0.2 - hotspot 5ghz doesn't work

Hi,
As per subject, has anyone else got issues when activating a hotspot at 5ghz? 2.4ghz works fine, 5ghz doesn't.
I didn't have any problems when running 5.1.11
Thanks.

Hmm I think I saw this today on my phone. I tried to connect to hotspot, then it disappeared (on network on my laptop). Switched hotspot off and on a few times, it didn't appear again. Changed to 2.4Ghz and it showed up on laptop and was able to connect. I'm on latest Beta OOS.

Exactly. It works fine @ 2.4ghz but it just doesn't @ 5ghz. I can't even see the network.
Maybe someone else can comment on this.

Yes, that's right: Open Beta 6 + xXx 2.9.8 ( see here: https://forum.xda-developers.com/on...xxx-nolimits-1-0-speed-ram-optimized-t3799167) + I forgot to mention: kernel blu spark r51 (https://forum.xda-developers.com/oneplus-6/development/kernel-t3800965)
All the best !

I know I'd be annoyed if this doesn't work on my OP6, but I have to ask.. I can barely hit 25 down on T-mo when I'm out and about.. what's the benefit of using 5GHz over the 2.4GHz band for this purpose?

@joesee Overlapping channels at 2.4GHz in urban territories.

This is how it might look:
If it looks like in the 2nd picture, you'll probably get up to nothing over the 2.4GHz network. So you have to use 5GHz.

Ok, thanks. I thought about heavily used channels, but doesn't most WiFi euqipment now auto select channels based on the least amount of activity? OR does it only scan for crosstalk once then not actively manage channel selection once linked? I used to keep up with this stuff, but not since I changed careers. My thought was the 5GHz transmitted with much less power and the performance drop off was astronomical - especially with low powered devices like cell phones.

Yes omg. I'm so glad I'm not alone with this issue, exactly same as yours.
My 5GHz hotspot turns on but no device is able to see it. 2.4GHz working fine. Only happened after installing pie.
Some stuff:
I have factory reset my phone and completely reinstalled OS but the issue is persistant.

me too doesn't work

Just wondering, how many of you use adaway?

Is it possible to downgrade from A.22 to A.20 on the Rmx2075 version

Like the title says, is it possible to rollback to an earlier firmware. I seem to be having an issue with A.22. It keeps rebooting while I'm connected to my car on Bluetooth...
I have factory reset and it still does it..
I've had the phone 3 days. Out of the box was version A.18 and immediately it updated itself to A.22
I had no time at all to use it with A.18 so I don't know if the phone or firmware is at fault.
I am trying to see if one of the apps I have installed is causing the issue. But I was thinking it may just be quicker to rollback to an earlier firmware...
Is there any program, like Samsung's Odin for example, that I can use along with the A.20 firmware I have.
I have looked all over Web and can't find anything.
Or failing that, sucking it up and waiting for next firmware release. How quickly do Realme release firmware.? Coming from Honor Note 10 and that was often at all..... Lol
Sorry for the long winded question and thanks it advanced..... [emoji1303]

Well after a few days of extensive trial and error, it seems its not the Bluetooth that's causing the phone to reboot, but using the GPS.
Every time I use tomtom, Google maps, sygic etc the phone reboots..
So I'm gonna have to wait to see if its a hardware issue or firmware... Waiting for next firmware update. If it still does it I may have to return the device.....

I'm also having an issue where the phone locks up, screen goes off and phone reboots, When I force my phone to 3G or 2G only then it doesn't happen. So I think Realme has messed up 4G. I hope they fix it in the next update.

OK thanks for the tip. Not tried that yet.... [emoji1303].
What I don't get is why mine only randomly reboots while using GPS sat nav apps.
Does yours do it whenever? Or only in the car?
How do you force 3G only. As I don't have that in my settings..... Only have 2 choices
5G/4G/3G/2G/ OR 4G/3G/2G.
I have mine on the latter and have also turned off 'Smart 5G' option.
My next trips to work I will turn off mobile data, thus only having 2G, and see if this helps...
And yes let's hope this gets fixed in the next firmware update.

You can use an app called Radio switcher in the play store, mine only reboots when I'm getting a 4G signal, when I'm forced to 3G only I never get a problem.

I've received no fix yet, maybe when the next security patch update comes through..... I'm still on May security patch.
So far my phone only reboots when using a GPS app. Tomtom or Google maps for example. Otherwise don't have an issue. Haven't actually had a Chance to try radio switcher workaround yet.
Yes everything is in English when selected during first set up.... Not come across any Chinese.
From what I understand RMX2075 is the Global Rom, RMX2076PU is Indian Rom, RMX2076EU is the European Rom and RMX2071 is the Chinese Rom. But I may be mistaken.

Thanks! It seems for some reason very difficult to figure out which models go with what, like it's a big secret.

If you have problem with your realme x50 pro rmx 2075 send message on facebook to GSM Mafia. They unbrick my phone in under 20 minutes. Really good and fast job.
