It started today. Everytime I try to connect to my WiFi connection, it goes in a loop of connecting and disconnecting and finally it says "Avoided poor internet connection". After I click connect, the signal drops from maximum to 1 bar. I'm on Arconium ICS, but I've been using CM9 before and I had the same problem (that's why I switched to Arconium). This issue seems to be present in all the ICS ROMs. Any idea to fix it?

There is another solution made by Mike Duskis at android.stackexchange.com/questions/22848/what-does-avoided-poor-internet-connection-mean (xda forums won't let me post the whole link). The solution involves deleting the files inside folder /data/misc/dhcp
Assign Fixed IP address
Hey i had the same problem on both Stock Rom and CM9...i did delete the files in the DHCP folder...but the problem kept showing up every few days....but i solved it completely by assigning a fixed IP address to the network...on both the router and phone
so this is it
Your device manufacturer/model : mito a300
Your mobile operator : XL,simPATI (dual gsm)
A dump of system log messages. what message?
Your ROM information : sorry i dont know,but i use stock rom
What you've done and what's not working : turn of wifi and turn it on,do same with the router,wipe data (phone) , reflashing,and use your apps :crying:

Turn off WiFi setting
What has worked on several of my android devices and my Win 8 computer is:
go to "Settings" and turn off the wifi. Wait 30 seconds.
Turn it back on and most devices will quickly connect.
A simple fix for the devices in my house. Good luck!
Hi,
Out of the blue, I can't find any WiFi networks. NONE.
ALTHOUGH, if I enter my network's ssid and p/w manually, it will connect.
What the heck.
I just recently flashed stock, but when I did that it worked flawlessly. I also edited build.prop and deleted some bloatware, but I restored everything back the way it was and it still fails working.
No WiFi network is found. Anywhere.
The weirdest thing, is if I download some random WiFi manager from the Play Store, it finds every network available..
Anyone?
Thanks.
Anyone please?

Another wifi problem
Hi and happy new year,
I have a problem with the Wifi but not the same as you.
It's very strange because I can see all the neighborhood but I can't connect successfully on known networks.
I've tried with many networks with no success...
Sometimes, the wifi disappears and it shows disconnected.
Maybe it's a hardware problem.
Thanks for your help,
AkuaBlue
Another bump I guess.

Have you tried not synchronizing your phone with google account after reset? It pulls list of known networks from server, it may have had affected searching of new networks...

I hadn't.. Do you think that could really cause it not to find any networks?
Also, is there a way of erasing that now? Or do I have to reflash?
Either way I'm going to have to use TB to get my apps and data back.. Do you think maybe that has something to do with it? (I only restore user apps though)
Hi there,
Excuse the novice. Just got this 2 days ago and I am still trying to figure it out why I can't access the net at all.
I have not got Android experience much and I am digging now how to come out of this situation.
So no option to access Net at all. The Error in response is " Couldn't sign in. There was communicating problem with Google servers . Try again later." So this is like a loop there.
Android Version -5.1
Baseband Varsion - MOLY.LR9.W1444.MD.LWTG.MP.V16.P10
Kernel Version - 3.10.65
Build Number -ALPS.L1.MP3.V2_NB6753.65U.L1_P22
Custom Build Version - Elephone_P8000_20151014
I must admit the Phone came preset and once I have switch it on it picked up GMT time without I have set anything.
I will appreciate any help or pointing to a resources to try to solve as now it is unusable as I can't download anything.
Thanks in advance.
Check:
Settings --> Data Usage --> (cellular provider tab) --> toggle 'enable mobile data'
See if that's the issue. Good luck.
Now Stacked to The Elephone Logo on and unresponsive.

Thanks kevvyboy,
I can't do anything right now. The phone by itself (really) got in a mode I can't read even with letters so small, went to the Android Man with red Mark and now is in front of me unresponsive with the logo of Elephone totaly unresponsive.
Just to underline - I have not touch anything- I have left it on stand by last time I have played with it.
Any clues and help please will be much appreciated.
PS. NOW I have managed to (I guess Switched it off) and again on and there was window with APP UPDATE - came to 116 out of 116 updated and now again can't access the net neither Google Play.
Could this be a OTA Update completed somehow?
Thanks everyone in advance!

Hi again,
I have enabled the cellular data - no luck again.
When I am trying google play again message Google servers can't be reached and the more interesting - using the - preload browser it try to search trough yahoo search. This phone was sold to me as new, but I am starting to wonder what it has been through before it reached me?
Will a flash using PhilZ Recovery will help?
Could someone point me the way out of this please?
Thanks!
New bizarre Message.
Hi again,
Just to make it more interesting out of the blue it Popped up a Message box with following wording.
"In a Previous Android Version You have disabled all Google App services. Do you want to enable them. Yes/NO,
Of course I have chosen Yes and Again Can't reach net neither via Cellular data nor Wi-Fi.
Any useful contribution will be much appreciated.
Thanks!
Stuck on Airplane Mode? Try toggling it on and off. I remember my HTC OneX having an Airplane Mode issue - had to toggle on / off several times and reboot.
ETA - faulty APN settings for your provider? May explain a mobile data issue, but doesn't address the wifi issue.
Dammit.

Thanks Kevvyboy for your contribution.
Somehow I have managed to get the Cellular data connected and now have updated the Google Service.
WI-FI still an issue. Is there any sense - updating a driver (if I am not asking stupid question here)?
Thanks!
Glad to hear at least cellular working! The wifi issue is a bit of a mystery to me though - I'm all out of smart ideas, sorry
Hopefully some other bright soul can chip in.

download drivers for SP flash tools and SP flash tools program.
go and download mediatek drivers and sp flash tool.
you can get these from elephones website, google or where ever. i got mind from needarom. i used the latest versions for both.
i downloaded the 5th November 2015 firmware from elephones rom. it came pre 7-zipped. i unzipped it and left it's structure.
installing the drivers part:
you need to disable signature enforcement in your OS to install the drivers.
open SP flash tools.
load the scatter file in the official rom folder you unzipped with 7 zip.
at this point press the download button in SP tools.
switch off your phone. connect the usb cable to the phone and the computer.
you should now have the latest firmware on you phone when complete.
please note it wipes everything, so back up anything important to you.
once done, set up your apn in settings, mobile networks, access points.
wifi should work after a clean factory reset if you don't have a dodgy device.
elephone only supports 2.4ghz for wifi as far as a i know.
also make sure your network bands and are supported by the p8000.

Hi El_Nino9,
Thank you for the reply and sorry I am delaying my response. I have actually done some of the suggested previously once I read more on the site - thanks for the contributors here. I had Eragon 9.5.0 Custom ROM set with Philiz recovery tool after Mediatek driver download but the wi-fi is still an issue.
I will try to perform the the one suggested from you, I just have located the latest Elephone p8000 ROM on the Elephone site and will perform this on a first chance I have. - most probably on Friday.
Thanks once again and I will post an update from the outcome.
OK!
I have done the upgrade to the 05.11.15 Stock ROM.
Have made a Factory Reset and the Wi-Fi is working as before but I can't reach internet basically.
Again after attempts to get to Play Store or to or to perform a simple Google Search it comes again after message "Just a second" and after 20- 30 seconds it end up with the message.
"Google Server can't be reached at the moment please try again later."
Any help on this will be much appreciated!
Thanks a lot in advance!
P.S>
I have just discovered that the icon of the WI - FI showing a processes going on but I can't reach My Router URL for example through the Local network.
Does it mean this is really dodgy unit or I am missing any settings or there is any cure for this?
Thanks again!

so your mobile data still works on the latest firmware? specially after typing the correct apn settings?
regarding your wifi, where is the router in relation to your position? far away? standing right next to it with the phone? whats your encryption for your wifi? tried changing that to a different type and seeing if it connects?
if you have big concrete walls and live in a nice solid building that may too cause signal not to reach. the wifi isn't that great on the device speaking from experiance in comparison to other devices.
if all fails... possibly dodgy device

Hi EL_Nino9,
I guess either the p8000 not like my D-LinkDIR-655 router or I am missing something in general.
I have an extension for the other rooms and the phone connecting to a simple TP-Link with no hassle at all, but D-Link is like a brick wall - you see the wi-fy working but no internet access.
It is still a mystery.
At least is proven the wi-fi module is working.
Believe me - I have tried to alter the setting on the route and still can't get to the net content.
Will keep exploring this and will report if any luck.
Thnaks!
I´m facing the same issue here. Google-Services like Google-Photo, Gdrive, Inbox are not working. Any solutions so far?

Hi kraftmaschine - I have discovered that my aged D-LInk DIR-655 was giving me problems dropping out the signal. I had an access through mobile network and through my other room extension rooter, so I got on mind either compatibility issue or router problem. So I have upgraded the router and voila. Everything got sorted.
Also upgrade to the latest mod - not OWA but using the standard methods described here.
Hope that helps.
I'll try to give as much information as possible.
Yesterday I was surfing the internet and suddenly my phone froze and randomly restarted. After that I wasn't able to connect to wifi nor bluetooth. I was running android 6.0 with 30B modem, rooted and with TWRP. After that I flashed Modem from v21C Firmware. I don't know if doing such was responsible for the next thing, but my Wi-fi mac adress and bluetooth adress disappeared from Hardware information. Note that my IMEI information did not disappear.
After that I did a full factory reset with .TOT method. That didn't solve my problem. Tried upgrading to lollipop, did not work. I've done like 10 factory resets only today, I've tried to fix persist partition following this guide http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576, same results.
In 4.4.2 and 5.0(all versions I tried from lollipop), both wi-fi and bluetooth adresses showed up as anavailable. Sometimes after rebooting, my phone would connect to wi-fi and show my mac adress, and would crash after 30 seconds..
On 6.0,my mac-adress shows as 02:00:00:00:00:00 and bluetooth adress as unavailable.. Need some serious help here, tried so much stuff nothing worked..
I'll attach some screenshots that may be useful
Any questions and any tries to help me are highly welcome.
Enjoy 6.0 on your phones and thanks for reading :fingers-crossed:
-------------------------
Edit:
Adding some logs. Half a year passed, no solutions.
1 out of 100 reboots wifi works. I've gathered some logs of 1 of the moments wifi works. Hoping someone can figure something out. Tried lots of roms, nothing seems to work.
Forgot mentioning that both wifi and bluetooth show as trying to connect on notification bar, but when I go to settings and press on them, both say "turning on (wifi or bluetooth)" when the button is grayed out and off..

More info:
During the night, I removed the battery from the phone and booted my phone. After that Bluetooth would work, and Bluetooth adress would show up on "Hardware informations". Then, I turned off bluetooth and tried to put it back on. Bluetooth adress disappeared and my bluetooth would not turn on. Hope anyone helps..

I'm having a very similar issue. Wifi and bluetooth won't turn on and cycle. On some reboots, Wifi will turn on but the phone will shut down shortly thereafter. I've tries several different ROM's and can fix the Wifi, but no the power not the shutting down.

I'm having the exact same problem but a bit worst. I can't even turn my phone on. Phone came back from repairing, guy couldn't fix it. Tried some rom's, many "fixes" from the internet, nothing. Seems like the only way to solve this will be by hardware..
exactly same problem with my g3 too
even i was using stock 30b firmware and after one week of usage it suddenly crashed and stuck in bootloop hence downgraded to lollipop and tried all roms,factory reset,different modems etc but still not fixed
waiting badly for an solution
I'm having pretty much the same problem, along with overheating and screen fading. I'm using stock Lollipop, never rooted. I've tried a factory reset and a new battery with no results.
Any solutions?
Guys I've sent my phone to a local repair shop and they said they took it to LG's official partner.. I've been waiting for a while and it doesn't look good.. A friend of mine bought a g3 recently. I suspect this problem comes from a corrupted or missing file. I'll ask him to help me on checking files if the local shop can't find a way to fix the phone. If everything fails, the only possible solution I see is a new main board or a new phone..

what is the exact problem ur facing in ur phone.
Hello guys, a year ago I tried root my phone and got bricked. After 2 weeks I finally fixed and came back to the stock rom. Since that day my WiFi is not connecting.
I'm able to search and find any network, but when insert the password, the phone try to connect, the signal go down, the message "connecting" appear, and after that appear as "saved" but not connected. I already tried to define a static IP address, but didn't work.
Can I broke the wifi firmware when tried to root for the first time?
Someone have an idea on what is going on?

Follow the unbrick guide method 2. Make sure you follow it right.. Don't skip any parts because it doesn't work. Don't see how you bricked the phone by flashing SuperSU but okay..

Hmm, if that and the unbrick isn't working then you might want to ask yourself it something is broken. Does it connect to other networks?

No I ve used several different hotspots to connect. The strange thing is that mobile data are working.
hmmm take a look at this thread:
https://forum.xda-developers.com/oneplus-3/how-to/radio-modem-collection-flashable-zips-t3468628
If that doesn't work try to flash ex kernel if i remember it correctly it changes something with wifi to.
If that doesn't work then It's broken or you can fix it by doing something else but dont know what, Good luck
