Maddening wifi problems with Captivate

Ever since I got my Captivate, it has had issues with wifi. It's not my routers, or any configuration in my routers, as it happens with 3 different routers (not to mention that I work in IT, so it's definitely not the routers).
Here's what it does. When you start with a fresh boot, it works perfectly fine. As the day goes on, it gets worse; it starts dropping the connection randomly, and eventually stops working altogether. This wouldn't be so bad of a problem, but the point that it "tries" to start accessing a wifi AP, it drags the phone down in speed, eventually freezing, causing me to ave to reboot the device.
I already tried all options with wifi sleep policy; I've tried 3 different ROMs; I've tried clearing all wifi settings and letting the ROM generate a new .conf file, I've tried different wifi firmwares. Nothing works as it should.
What should I do now? Does anyone have any tips for me? I know it's the OS and not the phone, because the last ROM that worked perfectly was Perception 4.
Thanks for the help.

Easy fix I found.
Open Allshare, it should have come pre-installed.
Connect.
Your Wi-Fi problem should be fixed.
You will have to repeat this step when switching between locations, or when you come back to the troublesome router. I don't know why this works, but it does. It seems to have helped alot of other users in other forums with this problem. Maybe someone should make a sticky of this...seems to be a big problem with 2.2 Foryo.

Similar experiece with both an EVO and Captivate with a Linksys router and DLink wireless AP. Whenever I walked into the house, the other PCs attached to the router would stop working, the phone would not get data although it showed as connected and I had to reboot the router - both wired and wireless clients. The Linksys was a very old firmware and I had bad experieces with flashing a few previous devices. I ditched my Linksys for a DLink 8 port and wireless and have not had the issue with either the EVO, Captivate nor any devices attached to my network.

This is news to me. You are correct, I do have Allshare. I'll try it the next time I have the issue.
What if I simply remove Allshare? Will that fix the problem?

I have 2 Linksys routers with the latest firmwares, and one D-Link. No matter, it does the same thing with them all.
I should also mentioned that I already tested with changing the router's wireless broadcast channels, signal strengths, firmware updates, the whole 9 yards. The problem is the phone, not the networking equipment.

I used this on 3 Captivates in our house and they are all working great now. Had F&*%%#ed wifi issues before that. They are all ok now. Hope it lasts!

I'm not sure if that will work. I don't think this is by any means a permanent fix, but a temporary work-around. I think it just kicks the wi-fi into gear again somehow...=-(
Hope it helps someone out though.

I had a friend who was having issues with her phone not even attempting to scan for wireless, seems there is an issue on android phones that the networking cache file or whatever it is gets cluttered and needs to be renamed. (Android recreates it)
The process is rather simple, I walked my friend through the steps over the phone w/o issues.
I had her use oneclick root/unroot to root her phone.
http://forum.xda-developers.com/showthread.php?t=739304
Then Had her go through these steps to rename the file.
http://androidforums.com/samsung-moment/46179-unable-scan-networks.html
The steps are for a samsung moment but still work. Also noted that the steps w/o rooting do not work. After you finish renaming the file you can use the application in the first link to unroot the phone and go back to stock

SlappyMcgee seems to have the best fix

It wont hurt anything and I suggest just renaming the file to .old instead of deleting it. the entire process takes like 8 mins

Link doesn't work, at least for me.

Update:
The Allshare thing works. The problem is that it's not a feasible workaround, because you have to keep doing that every time you want to restart the wifi after the screen goes to sleep or what not.
I will next try that config file delete. I read up on that last night, but didn't think that was it, because I already did a few ROM installs which didn't seem to clear it up.

Little early for me to say this is working for sure. But ill be damned if it didn't, at the very least, temporarily fix it. Instant reconnect. Doesn't hang. Seems like it might be the real deal, for me at least. Ill come complain if it craps out again.
Edit: .... worked for 15 minutes. Aka doesn't work...

I tried all different ones. Firebird and Speedmod mainly. When I flash newer versions, I always wait till the battery is 100%, and I clear the Dalvik cache. Nothing ever works.

i had wifi issues and still do. my girlfried does too with her Aria. The phone really seems to only work on routers who have a DNS set to google. The bar near my house it flys and at home i was getting no wifi so I changed my router DNS to google from comcast and its fine. I agree there is a problem but not one that is going to get fixed by Google

My wifi workaround
I had two captivates which both had problems with my home router. Reseting the router never fixed the issue, but resetting the phone did, at least for a few minutes.
I found that phone has problems using DHCP with routers that assign addresses in the 192.168.1.xxx range. It seems to be a conflict with some other internal IP in the Captivate or something. To get around this problem, I had to change the local address of my router to 192.168.2.1, and change the DHCP range to 192.168.2.xxx The new subnet cleared up the problem immediately for me and it hasn't returned, at least, not on my home router. Unfortunately, this won't work on hotspots or other networks that are stuck in the 192.168.1.xxx range.

I ran into this problem on my Router. Netgear wndr3700. For some reason when I turned the wifi on my phone either the router was assigning it the same address as my Tivo or my phone wasnt accepting anything but that address. To resolve I forgot the connection my phone then reflashed the firmware on my router. Then reconfigured the wifi on my phone. After that no more issues.

Well i honestly dont know whats wrong with mine. I've done all the "fixes" in this and other threads but it doesnt work. What is weird is that it connects using All Share and only All Share. However it does connect at other places like my friend's, sister's, granparents and gf's houses. I think I'm gonna go to att and demand a new phone and an upgrade

Just wanted to post an update on this. For the most part, deleting the wifi configuration file in data\wifi seems to have cured the problem. The wifi signal did get stuck on one or two occasions, but I'm bound to believe that the issue was caused elsewhere.

[Q] cant connect via wifi!! vodafone (SOLVED)

Hi anyone with previous experience on vodafone
Im reasonably down with how android works (after owning,rooting and flashing etc for 18 months with Desire)
but why the hell cant i conect via wifi!!
i can connect to networks ok but phone refuses to pull in any data be that mail, facebook, market or internet
Seriously, i cant figure this out at all, anyone have an idea ?

So you can connect your phone to a wireless connection, it just doesn't download anything? In that case, have you checked the same wireless connection with another device?

Yes and Yes....im seriously stumped !
the only thing i can think is that theres some sort of wifi radio issue on my phone , but id have thought that would manifest by not connecting to the network rather than not pulling in data .
ive factory reset phone a couple of times and reset my router, no issues on other devices
think ill go back to the store for exchange as im not really prepared and shouldnt have to piss around with a brand new device
its a weird one

Have you tried changing the channel of your router? Try a lower number, like 11. Or temporarily removing any encryption and/or changing encryption type?

Did u try resetting your router? I had the same problem last night. Taught it was my phone. Ended up being my router. Go figure ;-p

Tried that....now at work and connects fine to the network, deffo must be an issue with my home network
Problem for me is that networks and the like aren't really my bag , ive had a look at the admin page on the router and can see its connected and theres nothing immediatly obvious that i could say "that looks suspect"
so im not sure what the answer is
all my other devices mac, pc ipod/phone and previous htc work well and have never had an issue
getting on my tits a little
ill have another fiddle later and see what i can do
cheers for the comments tho
otherwise, i do like the form factor of the phone and ill even give sense a good go befor i probably switch over to ADW or maybe launcherpro

Solved!
Set up static IP address on phone ..... Worked like a charm

I find the same, except I think it has to do with encryption. I have tried with wep and wpa and I get an IP address but cannot browse. On unsecured it works just fine.
Like you found a static IP works, but I think it is the static DNS that is actually the issue here.
This is a cumbersome workaround if you use wifi all over the place, so I downloaded Static Wifi which says it will store settings per connection.
The only issue with this is that I think the device has to be rooted for this to work

Have you tried using the opendns settings
208.67.222.222

wifi reconnect
Hi all
Perhaps we all have the same issue
I have the HTC Sensation with almost 2 weeks now and i am having one continuous issue.
I have wifi set up at home the phone connects ok,however i also have a TV/Video sender,when i need to use the TV/Video sender i have to turn off the wifi(not ideal).The problem occurs when i turn off the TV/Video sender and turn the wifi back on,the phone will connect with the modem but not to the internet,Facebook,Twitter,emails will not sync,while testing i have discovered that if i "kill" facebook and Twitter and restart the apps all is ok again i.e facebook,Twitter and emails all sync.
Does anybody have an idea what is causing this ?

I seem to have managed to resolve this by setting the security to wpa2 and i also altered the dhcp scope to force a new range of ip addtrsses higher up. Since I did that I've had no problems.

try to remove the battery for a few minutes...if it doesn't work try to access another wifi because your router might be the problem.

nope....
battery pull definitely didnt help. I went ahead and adjusted my network router for dual band to see if that helps at all

Also have WiFi issues
I run into that as well. It says I am connected, even gives me an IP, but all my data still seems to go over the cellular network..
Very frustrating at home.

You can use Juice Defender to automatically disconnect data when you're on WiFi... I've been using it for months and it has worked flawlessly. You can also go into Menu... Settings... Wireless and network....Mobile networks... and manually uncheck "Use packet data" (this is what allows mobile data to connect).

I had these problems also I talk to one of the geek squad guys at best buy he told me that samsung products have problems with some routers because samsung products like to keep the same ip address which my conflict with other wifi products. So I bought a new router that was stronger and assigned my phone an ip address and that solve my problem.

I've noticed WiFi problem in my moto g 2015.
My home WiFi is not connecting, it reacts like gone through infinite loop. My home WiFi is having WPA2 protected access.
Every else's WiFi is connecting to my phone.
Please help.

It would help if we had much more details. A link to a video would be perfect. Does this happen with any other Wi-Fi networks?

Did you manage to resolve your wifi problem?
I bought the Moto G (2015) 2GB RAM / 16GB ROM for my wife and she's having problems with the home wifi. It often says there is a "connection error" and loops to try to connect again and then fails. Her work wifi seems to function ok.
Having read about similar problems with older moto gs, people recommended (1) turning on and off airplane mode. (2) changing channel number of router.
Both sometimes work and sometimes don't. But it's not really a permanent solution. I'm a bit reluctant to do a factory reset and reinstall everything if it won't resolve the problem. The device came with the latest firmware already installed (5.1.1) and I haven't rooted or unlocked bootloader so should be a pretty clean install.
Anyway, would like to hear that factory reseting could resolve this issue or not before trying.
Thanks for any advice!

Mine does it every now and then. I just unplug my router, wait a minute, plug it back in, and then it connects.

Yes. It works for me too. But what happens if you're on a public or work wifi where you can't reset the router? It doesn't really seem like a long term solution.
Is this a standard problem with this phone? Anyone else have a similar problem or preferably a solution?

Yeah resetting other than home router is not the answer. It's an Android issue as all my phones do it from time to time. I haven't been able to figure it out. The other "fix" if you can't reset the router is try going into the Wi-Fi settings, and forget the network/name, and then add it back as new. It takes longer, but it could work for you. That's how I get around it when connecting to work when it won't auto connect.

Hi, I had also faced the same problem with a open wifi network which is free for 15 mins ..
Other than that one ..i had every router connected to my phone..
I was thinking the problem is not in your phone.. It's in router which might be old ��
Because old routers will have 802 a or something which are in compatible to some phones..
Or the router is not allowing your phone to get connected.. As your phone is latest and it has advanced protocols inscribed in it..
Do one thing.. Shed some light on this now :
1) router model (if known to you)
2) phone models which got connected to that router and it's operating system version (like 5.1.1)
And there is also one more point.. I found our phone might find problems connecting to 5ghz band router ..while it works fine for smaller routers like 2.4ghz
We can decide when you dig some info about the questions I mentioned...
We will get answers

Just turn off wifi and then turn it on it will fix the problem

You would think it would be that simple, but it's not. It just sits there "Connecting", then nothing, then "Connecting". Keeps cycling like that.

My router is a netgear CG3100Dv3 (using WPA2-PSK [AES] encryption) and uses 2.4 GHz. I don't think it's the router's fault though because I've had many friends connect with a variety of phones and none of them have had the problem before. I currently have a Oneplus One (android 5.0.2) and have used a Nexus 4 and Samsung Galaxy S (1) on this router without problems. Maybe it's a problem with android 5.1.1 as I guess not many of my friends have it yet. I've written to motorola support but they still havent got back to me.

Strange. I've never had a problem before with wifi. Maybe I've been lucky until now. Yep - have tried forgetting and reconnecting to wifi signal. Again, a temporary solution that will quickly become irritating when there shouldn't really be a problem for such a simple operation.

It's a temporary solution but a pain in the arse if you have to reset the router every few hours. And as I said before, what happens when you can't connect to a router which you can't reset? (i.e. public, work)

Change the router's channel, then refresh the wifi in the phone.

Firstly i agree that our Moto G has some kind of issue with some routers.. but there will be solutions for them from the ROUTERS POINT OF SIDE to make it work
i have read about your router .. Things i suggest (if you have already done them then let me know )
1) your router has option to change MODE to get speeds more than 150mbps.. try changing that 802.11 MODE , restart your Phone and Router and also keep CHANNEL to AUTO , try changing the security WPA to others also..
2) your Wifi of your phone will have a MAC address , copy that and paste in your Router to allow this device..
i am still finding info on your problem..
the reason why i think your Router can solve the problem is : i had once read about 802.11 b/g/n/ac types.. i am getting a doubt that they are the ones causing the problem.. if you are aware of it
have a look at this bro once : http://www.smartmobilephonesolutions.com/content/cant-connect-to-wifi-on-android-smartphone

Ok. Will change channel to auto mode. It was already on "up to 300 Mbps". Will also put MAC addresss in the router.
However this still relies on having access to the router. What happens when you don't have access. If this is going to happen on many routers then I prefer to return the phone and buy one which never has this problem.

I'll give a wifi fix app a go to. But they just seem to automatically delete known wifi SSIDs and passwords.
Another option would be to root and install new ROM and radio, but would prefer not to.

Just a quick update if there is anyone else reading this thread with a similar problem.
I changed the channel mode to auto and that has seemed to fix the problem. The moto g seems to connect without problems now. I didn't enter the MAC address nor used a "wifi fix" app so far.
Fingers crossed...

I have the same problem. Wifi just stops working and had a ! Symbol beside the wifi icon. I have probably had a 100 phones and devices connected to this router without a problem. I have changed a bunch of settings the router and it didn't help.
Disabling wifi off then on works, but that is no solution. I will try anther Rom or kernel. I am on resurrection 5.1.1

Thanks for your help! I'm still a little wary that the phone will have problems in the future on other routers, but it's a good enough fix for now. Hopefully a later firmware update will sort it out.

Unfortunately, my wife took the moto g on a business trip last week and could not connect to any wifi signals (her colleagues did not have a problem).
Not sure what to do now. I'm in contact with motorola support but they don't have any suggestions yet (apart from blaming the router - which has never had a problem with any other devices!)

Wifi on but not connected most of the time?

So i know this is a widespread problem because im on my 3rd pixel 3 and i have exactly the same problem on every one.
When im at home wifi is on but half the time it isnt connected, but as soon as i poke about on the wifi settings it connects. Its like its in some kind of sleep mode or something. I end up using all my mobile data whilst indoors a few meters away from the router! Ive had a pixel 3 since it came out and just cant seem to fix this problem.
Please tell me its a well known problem and some one has worked out a fix

I have not had that problem, but you may be able to reduce the mobile data usage by turning off "Switch to mobile data automatically" in Settings, Wi-Fi preferences.

This is no a known issue and if you're on your 3rd pixel i don't think had anything to do with the phone. It's most likely an issue on your router side. Have you tried resetting it?

Are you by chance using WiFi which is configured as hidden network? This is typically done by checking the checkbook next to "do not broadcast SSID" checkbox.
If you are connecting to such network, there is a setting you have to check while setting up that WiFi connection. It is hidden in normal dialog and so it is easy to miss. This was the root cause for similar issue I have seen on my Android devices including Pixel.

Im not using a hidden network. The weirdest thing is whenever i notice its not using wifi as soon as i pull down on the screen at the top it will connect. like its been caught out lmao. was using the phone just now, an alert comes up to tell me ive used 2gb of data. so i pull down on top of screen and theres an x on the wifi icon, its on but theres an x (probably means not connected to anything) then a second later it connects. i dont click on anything it just connects whenever i pull the top bar down to check. its been happily eating my data while on sat in doors but as soon as i check that status it connects! its damn crazy!
This is exactly what it does every time without fail whenever i notice there is no wifi.

Fix your router bro

The weirdest thing is whenever i notice its not using wifi as soon as i pull down on the screen at the top it will connect. like its been caught out lmao. was using the phone just now, an alert comes up to tell me ive used 2gb of data. so i pull down on top of screen and theres an x on the wifi icon, its on but theres an x (probably means not connected to anything) then a second later it connects. i dont click on anything it just connects whenever i pull the top bar down to check. its been happily eating my data while on sat in doors but as soon as i check that status it connects! its damn crazy!
This is exactly what it does every time without fail whenever i notice there is no wifi.

The x on the wifi icon means you are connected to the router, but the router is not connected to the internet. Like everyone else, I think you have a router problem. Rebooting the router may help, but it may be time to replace the router.

Where are you located? It could be that your internet is unable to ping google servers. I have that issue whenever I clean flash, but I am in China so that is why.

This is not a widespread issue and as almost everyone has said, you have a router issue. It's possible that your router "sleeps" when nothing is trying to use it but that's just a guess. My suggestion, get a new router.
