I have a no name Chinese 7 inch Tablet (Kinpad I200), but it works suprisingly well. It has a Cortex A8 processor, 800 Mhz speed, built-in 2G and 3G modul (SIM card), etc. The op. system is Android 2.3.3.
The only big problem I have with that tablet is related to its mobile data service. After switching on the device, the 3G icon is on, and it works normally, up- and downloading data with high speed. But if I (a) lost the 3G signal because there is no continuous coverage where I am, or (b) switch on the WiFi connenction -- I never regain the 3G (nor Edge or GPRS) connention until restarting the whole system. Then I have data service again, even 10 hours or longer, but after another WiFi session or moving a poor-coverage area, the problem reproduces itself.
Reading different forums I have realised that different Gingerbread-powered devices used to have this (or similar) problem and the manufacturers issued firmware upgrades to resolve it. Although my tablet is Chinese, its manufacturer also has issued a couple of OTA updates so far and I installed all, but the data problem remained.
So my questions are:
1. Is there an app that could bypass the Gingerbread built-in mobile data handling and manage the connenction itself? (I am asking this because I learned that Android does not allow access to those settings from 2.3 Gingerbread version -- maybe this is the origin of the problem...)
2. If there is not any 3rd party application, that would bring back the data connection, maybe there is a way to simply restart the mobil data service (without resetting the whole device). -- It also would be some kind of workaround, because it is quicker than make a whole reset.
Thanks in advance for any suggestion or help!
Cheers,

I'm having a very interesting problem with the WiFi on my Eris. Basically what happens is that I can connect to a wireless network and use it for about 3 min, after that it still shows that it is still connected, but nothing will load in the browser, Facebook, etc. Is there a way to fix this or is it an internal problem with the phone?

It's more likely something that you can fix on the router. What router is it? Is the firmware up to date? Are you using any security (WEP, WPA or WPA2)? Which channel are you broadcasting on? Is it set to bgn, bg, or g only?
Also, are you rooted and, if so, which ROM are you running?
Just a few quick things I have noticed about the Eris and WiFi:
- the Eris tends to have issues with routers set to WPA security and TKIP encryption. If you can, it's better to use WPA2 (which uses AES), but if WPA2 is not available, see if you can set WPA to AES only, and not TKIP or TKIP/AES.
- if you are not broadcasting the SSID, try setting it to broadcast and leave it there. Hiding the SSID does not make your router any more secure than a router where the SSID is broadcast
I routinely access both a G mode (by SMC as provided by cable provider) and N mode routers - using both WEP (yup ....) and WPA2-TKIP with SSID broadcast on, and the Eris locked on easily & stay connected with no problems whatsoever - true of some of the newest Froyo and GB Roms released lately.
If SSID is turned off, then it's a NO go as it won't even connect.
Do you have any firewall and/or security suite apps running alongside the router that might be blocking the connection? Check the logs - also verify DHCP and ipconfig settings on your pc ?
It appeared possible that some sort of energy star/saver settings being flipped on after a set period of being in-active? (It's been mentioned elsewhere, check your wi-fi sleep policy on whether it's enabled "When screen turns off"? under Advanced / Menu on the phone (wireless & networks > wif-fi setttings)
Try changing it, disabled & re-enabled it to see if the changes help - is this on a particular ROM release or across several Roms? I'm running GSB v3.5 and it's flawless.
I use wep at home, but the network is open at my work and I have the problem there as well. The Rom I use is tenzo xtr, but I've had this problem on other roms as well. The sleep policy is set to never sleep

I have the same problem. Been that way for the last few builds of any gingerbread rom. The one I am using know MacRom was the only one I never had problems with but this new release I know have drop off problems again

My Eris' radio receiver (Baseband version) is 2.42.01.04.27 - which is supposed to be the latest release from VZW.
I'm currently on CS's latest CM7-V9 GB ROM and I haven't experience any wifi or signal dropoff/reception issues - and I barely get a working 3G signal (bouncing back-n-forth to 1X on the status bar) otherwise when I'm home (switched to CM7 from GSB b/c I had minor issues w. foreign/Asian characters not displaying properly when I used Google Translate.)
Might be worth a try - I did a full system data/cache/dalvik wipe and also SD card reformat - after moving/backing up NAND & Titanium folders, etc. to a backup HDD first - basically starting clear & clean before setting up the ROM to flash to avoid any issues with market/apps or traces of old data on the SD card.
And, yes - I did noticed wifi connectivity with at least one of the "other" GB roms for the Eris - apparently tied to CM7 itself and not necessary unique (like those SMS/MMS, Exchange server & even GPS issues. What's consistent is that it is not uniform or across the board, some users finding issues & bugs while others are reporting little or no problems at all. Just wondering if it's b/c we are pushing the edge of "envelope" too far & beyond its original designed limitations (Android 1.5 to 1.6) now to 2.3.4. Overall speaking, when I eased back the overclocking speed to very moderate level above 528 Mhz & use conservative tweaks, I tend to run into fewer problems if any - just my extra 2 cents worth.
Yup done everything you just mentioned to no success. I guess I will live with it or go to a froyo rom. Either way hoping to believing the world of Eris soon.

Hello Zx2ner88,
If you have tested your device with multiple wifi connections to rule out the actual wifi disconnecting then the next step would be to address the device. If you have the most recent software (Settings>About Phone>System Updates) and a simply battery pull does not assist the next thing to do would be a factory reset. Please keep in mind this will erase everything from the device so if desired please backup. You can do this reset by navigating to Settings>Privacy>Factory Reset>Reset Phone> and Erase Everything. After the reset you will have to reprogram by following the prompts and choosing option 1. Please retest wifi after reset. Thank you.

Question 2:
Signal refresh from market
Accidentally sent from my Google Nexus S using XDA Premium
Thanks Melvinchng for the tip.
I installed Signal Refresh but no help. It does its job, the signal goes off then on again, but the data connection does not come back with the phone signal. Only full restart helps.

Call *#*#4636#*#* , try to turn off radio, switch radio or anything
Hey, everyone. Using your AMAZING n00b guide and overall lurking of this website for several months since January I've done quite a few awesome things with this phone. Currently I am running Cyanogen Mod 7.1.0-Ba2tF-Olympus (any further information how I got there can be provided if necessary). I'm having a slight issue though. I've noticed that sometimes I'll randomly have no data or cellular service what-so-ever. To gain access to data and cellular service at that point I will then have to restart the phone, wait for it to boot, turn on WiFi, wait for that to connect, use an application like Browser or Facebook to test connectivity, if data transmits then I'm good, then AND ONLY after I go through all that can I disable WiFi and connect through regular data and cellular channels. I was wondering if this has happened to any of you and if anyone had any idea on how to fix it?
If you need clarification I'd be more than happy to try and sort my explanation out for you.
Thank you all in advance and I hope to hear from you soon!
Hello,
Did your APN settings are good ?
You can found it there : Setting / networks / Mobile Networks / Access Point Name.
Where are you from, what is your carrier ?
Regards.
I am thinking you need to flash a new radio.
Greetings,
I own a OnePlus 5T (128GB) and I am running stock firmware (OxygenOS 5.1.7), rooted and bootloader unlocked. I traveled to a country for which I have a local SIM for, but didn't have (yet) any data plan. What I did to prevent unexpected charges was disable mobile data immediately (I did the same to my wife's phone, which is on the same ISP), so that I could receive phone calls and SMS, but I won't use internet and obviously I won't make phone calls or send SMS.
What happened next is that my phone connected for 0 seconds to the internet every day at a random time during the day, triggering a 6€ expense for 10 days.
I searched through the data usage log to see if any app used internet, but it was empty.
Interestingly, my wife didn't get any charge, so I presume that the configuration I used to prevent access to mobile data was correct (it displayed an X instead of 4G+ over the chart showing the mobile signal strength).
What I'd like to discover is what caused the charges (I did get a refund since those connections lasted 0 seconds each), to prevent this from happening again. However, the phone has been completely unhelpful. I do have a data plan now, in case it's needed to perform some tests.
My best guess so far is AFWall+, it's the only application I can picture bypassing the "cellular data off" option. Those connections looked like DNS connections also, due to how short-lived were.
Any suggestion over how to diagnose this?
Thanks for your help.
This is my fourth Motorola phone in a row. I got it from Amazon and use it on Xfinity mobile. I have not rooted it, and I don't particularly care about advanced calling features, but it does have WiFi calling via the phone app. Unfortunately, my office is not super close to my router, and for whatever reason it seems to not be a problem if I turn wifi off manually before taking/placing a call. I also like to pace when I am on long conversations (or go on walks outside), but this remains an issue. Would enabling advanced calling resolve this? I'd prefer not to root the phone if I don't have to, but I suppose I could.
Also, in previous generations, you could restrict mobile access for certain apps or functions. I made a signal video call several weeks ago that used a full GB of data even though I was connected to WiFi (perhaps the same issue as above, but at least it never disconnected me). I haven't opened the app in weeks and it's still used almost 200mb of data even though I have background data restricted, and all the in-app settings prioritize wifi. I'd love to force signal (and others) to use WiFi only.
