Wifi lost after standby - Galaxy Tab Q&A, Help & Troubleshooting

Hello & good morning everyone,
I have a Galaxy Tab 2 7.0. WiFi, FIrst off I would like to say I love this lil guy! I am huge reader of e-comics etc... Everything has worked wonderful thus far. However, after this latest update that we recieved posts 4.0.4 I am having trouble keeping my wifi connection up. Now, to be more specific if I am using my tablet and have the wifi on I do not lose connection at all. Perfect, alas the problem begins when I put the tablet into stand by. Now, if it is in stand by for only a few minutes generally the wifi comes right back no trouble. However when I wake the tablet up after say 10 minutes or longer it WILL not connect back to the internet. Now, I have checked all of the obvious stuff i.e., I have a strong signal strenght etc... All of my other machines/devices have no problem connected. Oh, and this is a stock tablet I have not dabbled with a rom yet. Any insight into this issue would be greatly appreciated.

data connection gets stuck

hi there
as i mentioned in the thread description, my data connection randomly gets stuck. what means that the "up"-arrow stays lightened, and i cant connect to the internet, no matter what im using (web browser, tapatalk,...).
this seems to be totaly random, since i can not reproduce it.
this always lasts like 2mins and its all fine again, after that.
as far as i can remember this only happens when using the FoyoMod (both 2.5.0 and 2.6.0) not on any cm-rom, well for as far as i can remember ...
using wifi its working without problems
and another question, but this is for sure depending on TheFroyoMod-rom: i cant download attached files with tapatalk.
my device:
[email protected] 2.6.0 (all standart: kernel, vsel, frequencies,...)
Baseband: 3GSMEPU91a_u_91.09.04I
thx in advance for replies

I used to have those problems as well. I've deduced that it might just be a dead spot. When I am at school in a certain classroom, I lose all connection and get the same symptoms that you're describing. It might be a dead spot, in which you can't really do much about that.
thanks for your reply.
but i mostly use my phone at work, and there i stay at the same spot for 8h, even if i dont move my phone it works again after a while. i still can do calls, what means i still have a signal???
there is something i found on the web, its called dns-fix which i tried to apply usind aor, but when i do so, it replies: already applied. so i guess its already integrated in cm7

I guess it all depends on your office building as well. A lot of cement and basements make the cell signals hard to pass through, so you might be stuck. Are you able to use wifi?
When you're somewhere else, say, at home, does your 3G work properly?
its at home as well. its no congret there just shacks, but even under free air with nothing around me it happens. and yes wifi works perfectly then, it testet it at home, and also calls are able.
and like i said above the outbound traffic arrow stays lightend, just as it is somehow stuck.
well gues i just have to live with it

hrmm I experience the same thing sometimes.
I don't think this is limited just to Milestone/Droid. I have friends with Defy and Xperia X10 and they also get drop outs.
I think it must depend partially on the software (I seem to get better 3G connection under Gingerbread). Also when I restart the phone/reinstall the OS my connection comes back.
Also it probably depends on location and the cell provider.
I guess 3G is not perfect to rely on yet. Hopefully in the next couple of years it will be as reliable as ADSL! But for browsing basic stuff it works fine.
I know that one of the tricks that I've found works SOMETIMES is to turn the wifi on, then turn it off again. It seems to "wake up" the 3G and sometimes gets it back to normal.
alright then thank you for the advises

but following a post by sileshn, i flashed the latest crono rom (1.2). since that i dont get more than 600kbps down, i already tried the tweak i n the build.prop. is this just regular in this rom?
i tested somewhere, i know from previous test what speed i can get. any clue about that?

[I9000] No "internet calling" option in settings of Galaxy S Gingerbread

I'm sorry if this is a noob question, but even the omniscient Google failed to give me a satisfactory answer to my dilemma.
I've waited, prayed and even made some ritual sacrifices to the Gods of the mountains under the sea to make Samsung update the I9000 to Gingerbread. And all that for this one feature: to use integrated SIP calling.
But when I updated to Gingerbread this morning and looked in the "Call Settings" menu, I couldn't find the "Internet Calling" option. With a sinking feeling that the mountain Gods have failed me, I decided to turn to the Tech Wizards of the xda-developers for help.
I saw in a few sites that it is possible to enable the option, but I couldn't understand anything as i'm a total noob in these matters. My phone's details:
Model: Samsung Galaxy S GT-I9000.
Firmware version: 2.3.3
Baseband version: I9000DDJV4.
Kernel Version: 2.6.35.7-I9000DDJV6-CL198883
Build Number: GINGERBREAD.DDJV6
Please help me out here. I'm desperate to the point of doing something crazy, like getting a Nokia.
Sorry for bumping this up. Somebody please help me out here.

lol That's TOO crazy! Personally, I never used SIP or Internet calls. But if it's that important to you, you can try flashing CM7 on your phone. It has this feature implemented extensively in the settings. Besides, you won't come back from CM7. Everything else is pretty much inferior!
Or find another rom like XWJVH or XWJVO they have all the stuff

Okay, but is CM7 stable? I read that some features are not working properly. Anyway, i'll try it out.
I felt that using inbuilt SIP instead of Skype or Fring would lessen battery usage. I also liked the idea of dialling from the dialler and video calls over IP.

Wont that change the product code? That happened to me when I flashed a froyo leaked ROM. My phone had the product code as "KOR" instead of "INU".
And thanks for your replies, guys. I had almost given up hope.
I looked into CM7 and some of the bugs are a bit scary. Esp, the issue with the phone unable to charge when it is powered off. I routinely run the risk of a fully drained battery, even with daily charging. Besides, the gingerbread update has speeded up the phone considerably. So, I'm quite happy with it, except for the SIP thing. I'll have to consider it more before I make the jump.

That is not a bug, just operating according to CM7 spec. When you plug in the charger, the phone boots up. You can then turn the screen off and go to Airplane mode if you wish it to charge more quickly. No big deal.
As for the rest, there are very few standing issues left with CM7, and those tend to only occur on a case by case basis. However, it is an acquired taste, and rewards people who enjoy tinkering and learning about their phone and Android. Since it is so easy now to install CM7 and then return to Samsung ROMs if you need to, it makes sense to try it out and see how you like it.

I didn't know it boots up completely, even in the case of a low battery. Some person said that as soon as it powers on, it finds out that the battery is low and hence powers off again. It keeps going on through it cycle and hence never powers up.
Still i'll look into it. Thanks.

Nope....untrue. It just boots up. The behavior is similar to the iPhone / iPod touch.

After a 21-hour marathon session of flashing and re-flashing Eclair, Froyo, Gingerbread and CM7 on my phone, I finally managed to get CM7 working. After using it for a couple of days, I haven't found anything useful to justify the effort. Though the fact that devs are going into so much pains to develop this ROM is astounding. So I finally bought ROM Manager premium this morning to support the movement. Also I am planning to stick with CM7 for the predictable future. BTW, your guide for installing CM7 is amazing, rschenck. Thanks a lot.
As for the SIP feature, I tried it and found the results to be under-whelming. Quality is poor and implementation is half baked. I found Skype to be better. Also all my contacts are on Skype and none are using SIP. Finally battery drain was much higher than using Skype. Hence i'm not returning to SIP anytime soon. I feel Skype or Fring is better suited for my purposes.
Thanks for all your help, guys. And also thanks for introducing me to CM7.

State of CM9 alphas

For CM7 we had a thread with all the known major issues (and solutions) for the most recent roms.
CM7 now is almost perfect and pretty complete. CM9 is still in alpha though and (obviously) seems to have a lot of issues.
Can someone who flashes nightlies / kangs please give a short overview what doesn't work or what does cause problems? Also stability and power issues would be interesting.
Of course there are still problems with video hardware acceleration but what about other areas which are GPU relevant like browser, games or any app that isn't just a list really? What about the sound drivers, do they work in general? does listening to music while using other apps work that also output sound (for example music + navigation or podcast + navigation)?
I think this would be very helpful to a lot of people (me included of course )
Why didnt i think of that?
Silly me that reads this tiny thread... http://forum.xda-developers.com/showthread.php?t=1347118
I didn't find anything useful via search which I didn't know from blogs / g+; as I didn't want to read up on as of now 1256 posts in that thread I had hoped someone could take 1 minute of his time and give a quick run-down.
I was hoping for a serious answer or a sarcastic one which took at least as long to write but would be really douchy. You just linked the thread so I'm not sure what to think lol
i use cm9 daily and i have not seen much problems. its smoother than any other rom i used, the battery holds much longer. whe listening to live streams it would not last longer than 6.5hours, yet on cm9 it holds for 9.5, i also dont need to charge every night or have the battery drained in the morning which was the worst thing and happend for me on all the other roms.
what does not work... let me see, the latest version of opera doesnt work. sometimes it takes a long time to get a data connection, but i think that is because my wifi switches on and off a lot. other than that i dont have any problem and i definitely wont go back to any gb rom.

Thanks a bunch dude! The improvement on the battery from stock to cm7 was awesome already, getting even more out of it would be great. I assume you are listening via 3g right? getting more than 6 hours is quite an achievement there.
I switch a lot back and forth between wlan / 3g though so I guess I have to wait a bit for that to be sorted out.

no im listening over wifi, but the battery usage reflects all over for me, usually i had to worry about my battery even on 2g, now i dont have any worrys, even on 3g it lasts longer than on 2g before.i guess its because it basicly uses 0 battery while not using it while on other roms it constantly drained as if i was using the device.

I've been using Nova HD for a week now and even though I was sceptical at the beginning, I'm really happy with it. It's fast, no random reboots yet, no force closes. The battery is not super, but is is ok: I think I can use it for a day with normal use. I'm not going back to CM7

So is the hp tp ever getting jb? I saw teasers a while back but no news since.
Couldn't find another topic on the subject
Sent from my using xda app-developers app
Work is progressing on it. If you'd looked in all of the Touchpad forums, you would have found an oft-beaten thread about it in Touchpad General. It's being worked on, and will come when it is ready. Please don't ask for a date, because nobody knows, and the more you ask, the slower dev's will work.
i have to disagree. theres been no news since the little teaser video. who knows if anyone is still working on it. its being held behind closed doors so no one else can contribute. and people are basically saying "no one else talk about it or work on it because there might sorta be this one guy who may still be working on it but you may never know". and its kinda sad cause it feels like we are waiting as if this was a manufacturer release which is not what these forums are about.
+1^^ If we just had something, we could all work on it and give advice/opinions. Things could/would be moving at a much faster rate.

Do a nandroid before completely wiping in case you want to go back.
i saw that. its very interesting. a shame that its not daily driver ready. but, finally! an update! and, something actually released to public. this is more what xda is about.
its very smooth and there dont seem to be THAT many bugs besides the fact that audio does not work what so ever. Wifi works fine. Video doesnt seem to work either at least not in the youtube app it just says to retry. So ya def not a daily driver but besides all the driver stuff it is smooth.

Its a placebo effect. I have a Gnex with real JB, and the experience isn't even close. I'm convinced that project butter has a lot to do with the kernel now, because, cm9 nightlies still feels quicker, even with UI interactions. Which is mostly what JB is about.
Not trying to troll, just saying it like it is, with an unbiased opinion.. I want it to be butter smooth, as much as, anyone else here.
Sent from my Galaxy Nexus using xda app-developers app
for true "project butter" you need more advanced hardware acceleration. since hardware acceleration isnt working at all, its indeed not as smooth as it could be. butter is made up of faster frame rate ui animations that do work, and an old gaming trick called triple buffering. this is why one person will say its smoother, while another will say its less smooth.
So I had JB installed. I plugged my touchpad in and it registered as charging last night. Woke up with 0 battery. So in other words, it wasn't actually charging. Now my touchpad won't turn on at all. I get the plug that says unauthorized charger that everyone just loves!
Don't use this ROM!! If devs can read this, take off the link until that problem is fixed. Now I won't be able to use this for at least 24 hours...

Well, I don't know about everybody... But I don't have my original charger, so I use an extra charge block from an older Palm Pre... These are apparently lower in output amperage and when the unit is completely off will by default give a message about using the correct charger, but it does indeed charge although slowly, this message has nothing to do with the flashing as it did this bare stock... HOWEVER, after flashing this CM10 ROM I too woke up to mine being completely dead even though it was plugged in all night... The ROM was running great the little bit I had to play with it so far... I did not have this issue with the CM9 ROM, but can't help thinking that this not using the correct charging block has something to do with this issue... So don't feel bad, it's not just you, I have the EXACT same problem as you have stated... I'm charging with the unit off now and will do further testing, hopefully an easy fix for this surely... I want it to charge regardless of the block amperage, I have different chargers all around the house and office and have always used them all in the past without issue... I am a first time poster to XDA, but a far cry from a NOOB, and look forward to contributing more into the future...

P.S. - Great work guys on these android ROMS’s, I am/was a webOS lover like many of you I’m sure and just hate how that project has gone down the drain, it was without doubt, and remains, the best concept for a phone/tablet OS PERIOD... I used my Pre 3 and TouchPad stock right up to the point of becoming sickened by the lack of apps and long term device selection option... I do however love android and now have a newer Android phone for the obvious reasons (APPs, support, performance, latest hardware, etc) and am thrilled the good ol’ Touchpad is so capable... I really wasn't aware of how great the specs were on this thing until I looked into the CM9 flash... Plus I love flashing and customizing anyway... Much thanks to the DEVS that make this possible!!!... :good:
Charging problem as well
I installed the cm-10-20121216-Experimental-tenderloin... on Jan 3rd and it appeared that everything went well in the installation except that my TP won't charge while running CM10. I have to reboot into webOS to charge (using original TP charger) and after charging is complete I reboot back to CM10. Any suggestions for fixing this issue? Also, battery seems to drain much faster on CM10 than webOS. Is that normal? Other than the charging issue I'm loving my TP more than ever.

[Q] loss of network when leave my house

Hello I have recently got a samsung galaxy ace and have installed a couple of custom roms, i saw a thread for one of them to sort out the gps config, i tried to follow the instructions properly but did not find them very clear. I left the house the other day and discovered that as soon as i walk out the door of where i live my network disappears and is very intermittent if on at all. I have since reverted back to stock rom and installed cm7 rc3 democracy custom rom which is working perfectly at home but yet again when i leave the house it does the same thing and the signal just goes. I usually had poor signal in my house before but now this is the only place it works! I have looked on so many different threads but cannot seem to find the solution could someone please help me in the right direction to resolve this thanks
