Milestone Wi-fi/3G connects but not send data

Hello there,
As a newcomer, I found out these foruns filled up with great information and guys willing to help, so came here to ask for some help ....I am both excited and dissapointed with my brand new Milestone. Bought the handset about 5 days ago, which came with Android 2.0. Then updated it straight away to version 2.1 via "Motorola Software Update". So far so good ...here´s the problem I am facing :
While connected to wi-fi or 3g(issue is easier to notice due to 3G icon at the task bar, which points out in those small arrows data that is being sent/received) phone stops to receive data out of the blue. All connectios are cut off(it also happens when the handset is locked up). Some basic trouble shooting i did:
- tested all pcs connected to the same wi-fi network. No issues detected for these
- reset wi-fi router configs. Didn´t work
- tried other wi-fi router. Presented same issue
- swapped another carrier chip to test 3g connection. Presented the same issue
- tested my GSM chip on ther phone. Worked properly
- Reset phone to default settings. This time the connection took longer to drop, like 30 minutes, instead of the usual 10 minutes. After the first drop, it´s started behaving the same way again.​
It seems pretty much that there an issue going on here (obvious...hehehe). I am considering the following:
- Might be a software issue. So, right now i am downgrading it back to 2.0 version, check if it works properly and then move to 2.1 hopping to get the issue fixed.
- Use retailer warranty and claim for a new phone =/​
Could you guys help me out ??
Thanks in advance and Best Regards !!!

Guys, after downgrading version to 2.0, phone stills presenting the same issue. I think it´s turning into hardware issue =/....does anyone have a clue about it?
Thanks and Best Regards!!!

[Q] Crash/reboot at network reception !?

Hi
My TYTN2 keeps on rebooting as soon as it got connected to a network.
Strangely, it always happens in certain regions (for example another city), but not at home.
And always the same, I start the device (or just activate the telephone), it searches for a network, finds one and connects -- and then crashes.
After rebooting the same problem.
1-2 times it did not crash, and I was able to use the telephone, but 99% of the time it is the same problem, somehow related to the device (I tried another SIM card, too, but same problem).
Anyone who can help?

are you sure it's not a battery issue

i had the same problem, sent the phone to service, they changed the mainboard, but the problem persisted.
They sai it was a battery prob, but even with a new battery it did the same thing.
Now i am running android on my kaiser, which just won't connect on any network.

[Q] bluetooth crash 2.3.5

Hi everyone,
i searched on the forum before write this post, I hope this is the right section.
I updated my galaxy to 2.3.5 (I9000NEJVB, 2.6.35.7-I9000NEJVK-CL649158) starting from 2.2 with Samsung kies.
After this operation the phone works a lot better, but a serius problem is started to be present (always reproducible) with bluetooth.
In 2.2 version I only used one time the bluetooth, with a wireless mini keyboard. It's the only item i've paired.
After the firmware upgrade, when i start the bluetooth, android crashs and restarts cyclically: crash, restart, take network, scan media and crash.
Also removing the battery the cicle remain the same, because when i startup it remembers the bluetooth conf to be on.
If i try to switch bluetooth off in the few second when you can operate the phone, the bluetooth doesn't reach to be switch off .
The only way I found to break the cycle is connect to te pc in debug mode, and wait (if it comes) a popup screen with the confirmation request to turn off immediately the bluetooth, and fortunately this opearation works.
But sometimes I waited more than 10 minutes, with dozens of reboots, one every 5-10 seconds.
On http pastebin dot com slash rFvD81iN you can find the debug log, and the log starts few seconds befere i switched the bluetooth on.
I tried to remove the files in /etc/bluetooth as suggested in one post, but the problem is still present (now the folder is empty, there are not 'grey' paired devices in the list of bluetooth settings; the log was taken when the paired device was in the list).
Can anyone tell me how can I solve this issue? I can use all the feature of the phone, when bluetooth is off, otherwise it became unusable, and I have difficult to recover it.
thanks a lot,
regards
Francesco

I'm having the exact same problem (also on galaxy s i9000). Also just upgraded to android 2.3.5 from version 2.2. I managed to get out of the cylce of crashing eventually after about 10 cycles the phone actually booted sucessfully. I was then able to turn off bluetooth. Re-activating bluetooth then caused the crash cycle again. Oddley, it has now stopped crashing but I can't conect bluetooth properly to my iControl Pad device, now it just says it's paired but not conected. However, I fear the crashing cycle could begin again at anytime I try and use bluetooth.
My bluetooth worked fine as well as my iControl device on version 2.1, only issue was it lagged a lot!

I have the exact same problem, but with Galaxy SII (i9100).
I have Romanian Vodafone Galaxy SII with official software. I upgraded via Kies from 2.3.3 to 2.3.5 and everytime I turn on Bluetooth Android goes through successive crash-restart cycles. During every cycle, BT seems to be on and even if I try to turn BT off, nothing hapens. After a 8-10 cycles, at some point, randomly as far as I can see, it starts normally with Bluetooth turned off.
Any ideas on this?
Thanks,
Razvan

thanks nickmaymusic and razvancd, I'm surprised no one have any indication to how the problem can be adressed.
Anyway in my case the cycles continue for many minutes, and sometimes the phone became unusable.
I think to reflash the phone with odin, but I was try to found another solution, i need the bluetooth.

Try installing Android 2.3.6 using Odin. It's easier with Odin than using Kies.

I also have the same symptoms on Galaxy S2 Android 2.3.5 and Baseband I9100XXKI4 with Kernel version 2.6.35.7.I9100JPKJ2-CL655700 [email protected]#2 Build Number: GINGERBREAD.JPKJ2
This was upgraded via Kies in the UK in Dec 2011.
Bluetooth is effectively unusable and the device simply reboots repeatedly. I have managed to catch the unit during media scan stage and switch off bluetooth and this seems to (if lucky timing) allow the device to fully boot and remain stable.
In my view this is a high priority bug and the Android community really need to solve it quickly to preserve the reputation of an otherwise strong O/S.

Flash a newer relase with odin and the semaphore kernel!

Wifi, Wifi tethering and Bluetooth is not working

Hi,
I have Xperia ZR C5503 phone about a year. Until 2 months ago I was using Android 4.3. When Lollipop update distributed I upgraded it to 5.0.2.(official)
But sometime after the upgrade my phone started not connecting wifi. It sees the available networks but not connecting them. The signal drops to lowest level about a second while trying to connect and it fails. Also I was using my phone's wifi tethering feature to share my internet to my pc. However wifi tethering is also not working. I enable it but I think it can't work as router. And lastly, I tried to send a file to my phone via bluetooth and it also enables but no other device sees it. I also have low sound on the phone and I can't hear people I am talking to.
So I got frustrated this saturday and downgraded to official 4.4.4. But it was same. Later I unlocked the bootloader and rooted my phone, installed recovery software. With that recovery mode I cleared all caches but the problem still countinued. Lastly I installed an unofficial modified kitkat to my phone but those problems still appears. I don't know why this phone is so problematic for me. I don't know if it is software related or hardware related. Now that my warranty is no longer valid.
Could you give me some ideas to attempt to solve these issues?

Hi,
I had dropped my phone maybe 1 or 2 times but not from high heights.(~ a meter) But that was more than 5 months ago. I am having this issue since last 2 months and I am sure that I didn't drop or harm my phone in any way. However I wash my phone, do you think that could cause that? Just effecting wifi and bluetooth components?

It's not true about dropping the phone make that errors appear, there are many people with same issues, this phone have manufacturing problems, it's not software
My brother have same problem and he never dropped the phone. Just take a look in Sony forums.
Btw, my brother's phone lost Bluetooth connection, NFC, WiFi, Sometimes WiFi works making some pressing in the NFC spot some seconds, but sucks anyway :/

How can i make the wifi stable? it drops in and out sometimes.

Wifi problem
my sony xperia zr has the same wifi problem it says scanning trys to connect the signal drops and again starts scanning..
I stopped the wifi service and restarted my phone and the wifi worked for a day and again the same proble.
Do anyone has a solution for this??

I have been facing the issue of wifi not connecting, since my upgrade to 5.1.1.
My research has led me to believe that the issue may be software based. However I'm not an expert in the field. And i was thinking of downgrading back to an older version of lollipop when the wifi was not dropping.
Can anyone advise on whether this may be a smart move, or a completely useless one?
Also is there a diagnostic protocol I can go through that could help me figure out for sure whether my wifi is busted physically, as some of you suggest here.
Thanks
Josette

I've tried the method "settings global put tether_dun_required 0" but when i reboot my Z5, the value comes back to 1 ... (and of course wifi tethering is not working, going thru USB is ok)

I'm discussing various points here. Check out everyone of this point and get a fair idea from where problem is originating.
1) Go to WiFi Settings > Keep wifi awake during sleep. Here the string value should be "Always"
2) Under stock firmware there are numerous battery optimisation. Some of them kill WiFi so battery can saved. Now disable this features if you want no drops in WiFi.
3) If both of don't work, head over to Xperia ZR General > Search for your specific device FTF. Flash it via flash tool. This should reset all wifi drivers. Don't opt or apply any battery features and use WiFi. If still issue exits then you're in bad luck.
4) Check for other WiFi access points. Check your own router's webpanel and see somewhere broadcasting and multicast signals are ticked. Also check your WiFi is at 100% of it's performance ( 100% transmit power)
5) Hardware issue. Most of the software part is not causing issues so it's safe to say a hardware issue is causing this. Now, long time ago when 5.0 was released for our device I read article regarding ZR. The user had constant WiFi drops. His issue was that his WiFi soldering was poor inside hardware. He soldered it again and his wifi drops were no longer a problem.
People also experience various bluetooth/tethering issue. It's important that people should gain knowledge about firmware flashing techniques so that device would get reset and you yourself could diagnose the problem. 1 in 0.7k unit has software/hardware issue in manufacturing. Sony provides diagnostic app, search in play store ( I'm not sure about this). Hope this answer helps many.

hii.. so did u get any solution for the problem ?
i am facing this problem since one month. i tried rebooting my phone many times. i even tried factory reset. but nothing has worked till know.
if u have any solution please inform me.thanku

wifi disconnects for unknown reasons

My SM-N900A has been working great for a few years now and is running Android 5.0 from an OTA update (maybe a year ago). A few weeks ago I started having trouble with the wifi. Sliding the wifi control to "on" will sometimes work, but more often it can't find any networks. Often rebooting will fix it, and the wifi will connect (showing a strong wifi signal). Sometimes I see it rescanning several times when I don't think it should be scanning. Then after a few minutes or occasionally up to an hour it will disconnect from the wifi entirely and refuse to show any networks as before. Sometimes I have thought that disconnecting the battery is a surer way to restart the wifi than just rebooting, but it is hard to be sure. This happens with my home wifi, as well as with several other wifi networks I have tried. I haven't dropped or damaged my phone, so I'm wondering if this could be a software problem. I have tried rebooting in safe mode, but the problem persists so I don't think this is caused by an errant application. I have also tried swapping in my spare battery, but that didn't change the problem (although neither battery is a genuine Samsung). If I leave wifi off and just stick to the cellular connection, the phone seems to work as it should. Would there be any logic to trying one of the alternate ROMs on this forum to see if this could fix the wifi problem? One reason I haven't tried this already is that the directions I've seen for installing these ROMs seem to be written for people who have done this dozens of times (which I have not). If this is a reasonable tack, is one of these ROMs known for its ease of installation, or perhaps for the quality and detail of its installation instructions? Are there any less drastic things I should be trying first (other than buying a new phone of course)?

Got the same issue. used odine reinstall 5.0 modem/radio and when that did work, i reinstalled 5.0 and 4.4.4 but nothing worked. i think its a hardware failure. time for a new phone.
