Used barnacle.. Wifi problems

Alright. So I installed and used barnacle wifi to tether something to my infuse, it worked. However, when I got home I found it can't connect to my home router. I checked on my laptop and the network is fine. I tried restarting, re entering password for the network and still nothing. Any ideas?

Also, when watching the wifi connection in phone settings, I see it scanning then say connecting then disconnected. Then starts the process over again.

you restarted the phone? sometimes my router becomes invisible and turning off wifi and tturning it back on helps. maybe try turning on mobile ap mode let it give you the whole checking for tethering plan and you dont own a tehthering plan messages and then turn it back to normal wifi. it might just have something to do with the way the radio switched modes that disagrees with the app, or a total coincicence. sometimes toggling modes sets everything strait. sometimes there is an actual problem that may be fixed by clearing data or reflashing the stock rom, i doubt it damaged the hardware in any way.

Yep, just cleared barnacle application data and fixed it right up. Thanks

[Q] Wifi+Data issues

Hey Everyone,
I seem to be having an issue with both my wifi and data connections.
Last night, my phone randomly stopped loading web pages. No error messages, no time outs, it just doesn't load web pages. The status bar and settings both display that wifi is indeed connected, and it has an IP address, but it won't load any pages except, oddly enough, www.google.ca. If I do a battery pull, the wifi works perfectly fine, that is, until I turn wifi off. If I turn it back on afterwards, it stops working again. Also, data will not work. My phone is a g2x running cm7 nightlies, with Faux123's kernel.
Thank you in advance!

Data is a known cm7 issue.

Had the same issue. I had to do a full wipe. Do not restore apps backed up with app programs like mybackup or you will have to wipe again.

CM 7.1, data transfer will not work
Wi-Fi is good

P6200 WiFi Issue

Hey guys. This is my first thread here. So, I hope you can help me.
When I upgraded my GT+ to ICS then now to JB, I already had problems with the WiFi. I thought I would find the problem in the forums, but mine I think is different. There are two arrows in the WiFi indicator, the orange and the green ones. When these two arrows are both lighted up, it means that it is transferring data to the Tab or whatsoever so that I could connect to the Internet. Well, this is based on my understanding, hope you could still help me about this.
So, the problem is, whenever I open the internet and enter an URL, the green arrow stops blinking leaving the orange ones lighted up until both of them are already not blinking and then the browser says, "Webpage not available" (like the attachment below). It happens all the time and whenever I update my Apps in the Google Play, after, example: 23% of downloading the app, it stops and the same scenario happens again. What I do is, I will turn off the WiFi toggle and turn it on again and after, maybe 30 minutes, it happens again.
What do you think guys is the problem? Is it the router or modem's problem too? Or it is a software issue? Thank You guys! ))

Sent from my GT-P6200 using xda premium

Yes. I have tried it on my sister's S3 Mini. I never experienced that scenario when my GT+ was still Honeycomb. It just happened when I updated it to ICS.
These are also some happenings:
- When I will refresh the Accuweather widget, it will happen again. Both of the arrows will stop blinking.
- When I am updating 15 Apps (for example), again, Both of the arrows will stop blinking then it will stop downloading.
- When I am using Google Now then I said something, it will just show "Recognizing" then it sill show "No connection."
- When I am surfing the web and then I searched something, again the arrows will stop blinking, then the browser says, "Webpage is not available"
- When I am uploading photos to Facebook, same scenario again and then it will show, "No connection"
The WiFi is not disconnecting actually. It stays connected but it stops giving data. I'm suffering from this problem since ICS. I don't know what's really the source of this problem. That's why I'm seeking for help here in XDA. Thank youuuu.

Most likely your router is dlink? Change the router, use a tplink one

Okay okay. I'll try. Thanks!
My router actually is Tenda and I think it's already old. So, I'll try other routers. )

Make sure you have the correct wifi frequency band set on your tab for your region/or router. I'm not sure if the stock Samsung roms let you configure it. In aosp builds it's in wifi and advanced menu.

In the Advanced menu, it only shows the IP and MAC Address. How can I know the correct frequency band? I posted an attachment for the picture of the Advanced Settings. )

It seems the problem come from your modem.
I had similar problem like this. My wifi router connect to modem and sometimes this modem does not allocate IP for router.
This problem is most likely related to IP configuration issues. Let try to use some apps to list down all configurations and check

I only experience this every after flashing roms coz my apn settings always gets edited, what I did before if i dont want problems with wifi every after flashing roms using odin was I copied my apn settinngs and edit the wrong apn settings after flashing, or I remove sim card before flashing but I made a copy of apn just to be sure

APN has nothing to do with wifi. APN applies to your cell data connection. 3g, LTE, etc. not to wifi.

[Q] CM11 (4.4.2) problems with mobile network

Hi,
I recently flashed my I9105P with latest CM11 with Android 4.4.2 (http://forum.xda-developers.com/showthread.php?t=2568665). And everything seems to be ok, but there is one thing. Suspicious often I got information that "network is unreachable" , status bar says that I have 4bars of network coverage, but I can't make calls or even receive them. Restarting phone, or cleaning cache doesn't help. Does someone have any idea how to check or fix this problem?
Thanks

I had the same problem this week, but the last CM build was on my phone since 30th december, so i cant blame CM.
Solved it by changing the SIM card at a Orange Shop.
Try the phone with a different SIM, see what happens.

Had the same but later i click "choose automatically" and it solved problem for me

choose what? All I can select is prefered network (2G/3G), network provider is selected automatically. Somewhere I saw settings (I can't remember where) that allows me to choose 2G|3G or 2G|3G|2G+3G. But I don't know does it matters what option is chosen.

SHV-E300S WiFi turning off when idle

Hey guys, so I'm having this problem with my SHV-E300S , even putting the wifi config to always in sleep mode and using the code #*0011 to set off the wifi power saving, it still not working, so after around 15 minutes idle i cannot receive any notifications from messangers apps or email, i will receive that just when i unlock the phone and wait for a few seconds.
I'm using not the kit kat 4.4.2, but i tried the official lolipop 5.0.1 with no progress, also tried to install the cyanogenmod but i received status 0 error from recovery when i tried to flash the rom so cannot say if it would solve the problem.
I would be very glad if someone could help with that, the cellphone is useless for me since i just use that for messenger.
thanks

tried artware but the problem got worst, since i coudnt even turn on the wifi
instaled official lastest version available lolipop and the problema persists
after around 30 minutes the phone enter in sleep mode, wifi dont respond

You can do some searching for how to use wakelocks to either apply or deny wakelocks, this can be used for many of your apps and features to control when and how they are active. There are apps in the playstore that let you manage wakelocks.

Thanks for your reply, i'm testing now some apps to check if it solve the problem

Hi, i tried the cpu awake app, wifi keep alive and PNF app.
It's pretty hard to say that works completly since sometimes i receive, sometimes I receive with delay and sometimes dont Receive at all
I cannot think about what is causing the issue but i wonder if theres some clean ROM for this phone (without carrier stuff), original but without carrier software to try, or some another solution.
anyway, thanks for the help.
