My captivate has a problem. It'll connect to WiFi no problem. Unfortunatly, after a while (could be anywhere from long 30 seconds to a few minutes) the WiFi stops sending data. I have to disable/reenable wifi to get it to work again. It still says connected to network, it just won't receive data.
Anyone know of this happening, have a fix, or maybe what I should look for that might be causing this issue?
I disabled recently installed running apps, no help.
I did try a speedfix last night, and it was unsuccessful, and I uninstalled it. Didn't test enough after that to know for sure if it was the issue, but I don't think so.
It was like, I was going through google reader, started a youtube vid, paused it, restarted it, and it wasn't loading. Just wouldn't load. That's when I think the problem started, and I haven't installed anything since then, that i haven't disabled/uninstalled.
Have you tried flashing the stock OS. Maybe this will help. My wifi has been solid so far but i will see if i get a problem like yours. Try reflashing. If it doesn't work post back.

I have the exact same issue on enterprise class cisco wifi APs. The only difference is the symptom is immediate, and not after an interval of time.

I'm thinking of this, but I don't know...
I have my music on my computer, I have my .apk's in a folder and my market synced with appbrain. Anything else I need to do? Will appbrain reset, and make me go find and reinstall everything?
What about the apps that I paid for, what happens to them?
Would be my first flash, and I'm thinking about flashing one of those I9000 roms, but that would be a last ditch effort. I really hope to avoid this.

It's an AT&T U-verse router, and only started a few hours ago, as near as I can tell.
I experience the same phenomenon of dropped wifi, and it occurs at any AP, but I have an interesting twist.
One time out of twenty when I start wifi, the 3g icon doesn't go away, but stays up on the status line with my wifi icon. On those rare occasions, my wifi stays solid for days. Unfortunately, it's random and rare.
same issue
My Wifi stops sending data and the 3G still shows. Sometimes restarting the router helps and sometimes nothing helps.
For anyone that might find this later, turns out (after two rom flashes) it was the router. I found this out when connecting my laptop to it. Surprised the captivate didn't admit it lost connection though.
I wish that were the case for me. My Captivate stays connected, but stops receiving at many different APs--Home, Starbucks, airport. I need a solution or a Scotch.

I had this exact problem, I tried a factory reset and it was still broken. I exchanged my phone and now it works perfectly holding a signal (except for enterprise 802.1x ap's which are known to be broken). (Also if you run dd-wrt check your logs for "deauthenticated due to local deauth", there is a problem with the wpa/wpa2 modules in either android or dd-wrt that they are not compatible with each other).
I actually found this searching for a solution to my own issue with WiFi. I actually fixed it while I was reading this. Unfortunately I have AT&T DSL with 2wire Modem. I went into the setting and setup MAC filtering and assigned it it's own IP. It has worked flawlessly for the past hour. I know this probably will not help when at other locations but at least at home I have a good connection.

Same router type as mine that lost it originally. Interesting, wonder if there is a connection? Or random coincidence.
I'm having a wifi issue as well, but not to the extent others have.
I connect fine, but it appears as though my data download speed is capped at <2mbps for both wifi and 3g?
My wife's iPhone is getting download speeds of over 10mbps on the same wifi network and >3mbps over 3g.
Is it worth flashing back to stock? or is this a known issue?
I'm running stock JH3 with SRE 1.2.1a with lagfix
I have this same issue and it's really random. Running JH2, sometimes it works on wifi, sometimes it doesn't. Sometimes disabling\re-enabling wifi fixes it, but rebooting the phone always fixes it. Really frustrating...
Anyone else having issues with internet connectivity after the 3.1 update? None of the other devices on my network are having any sort of issues. I've already tried to remove my router and readd it again but no dice. Sometimes I need to refresh webpages 3-4 times before they come up, and simple websites too.....like Google.
edit: I see the icons on the WiFi icon blinking......but webpages aren't loading. Tested the YouTube app and videos take forever to load. Also tested in DolphinHD and Opera and they're having connectivity issues also.
no problem for me. Do a cold reboot

Yeh, I tried that too. I guess I'll see if the problem goes away in the next day or so, otherwise I'll go find some instructions on restoring the machine to default. Good thing i've been too lazy to load all my apps and data on this puppy lol....too lazy and busy just playing with the damn thing lol.
No problem here. I just update about 2 hours ago. WiFi has been online w/o interruptions.
My problem is that it wont see all wifi networks available! ? e.g I know at the office there are 2 wifi routers to connect too, it will see one but not the other and the one it sees it won't connect too?!
Ideas anyone?
Plus there is no option for setting a static ip with 3.1
Just a thought, I am sure I saw that the TF cannot detect WiFi channel 13. Is there a chance that those office routers use channel 13?
I had a problem connecting to my router. I just went into the network settings and "forgot" my network. Waited a minute and the transformer detected it and connected fine.
Same here: after a few hours, the wifi activity icon blinks merrily away, but zero actual connectivity!
I had to switch to airplane mode and back again for it to work.
Sadly, it's already happened twice since this the 3.1 update earlier today!!!
haha so I'm not the only one and I'm not crazy after all!
I'm getting an issue where the wifi indicator turns white but the arrows keep blinking. I have to log off then log back on for the indicator to turn blue and the data to start flowing. Pretty lame. All other phones, comps, and I pods are connecting to the router fine.
Hi folks, looking for some help.
I am able to connect my tab 2 to my home wifi no problem.
I have also connected it to my Galaxy s2 phone using wifi tethering.
What i have found though is that on several occasions when i am in work and try to tether to my phone, that settings will show that i am connected to my WI FI hotspot but i cannot connect to any internet pages. I recall many moons ago that when i sometimes changed modem connections on my home pc that i had to reboot everything to have the old settings forgotten and the new ones set. Does anyone know if there is something similar when you move from home WIFI as your last connection to WI FI Tethered hotspot as your new one. Is there something i need to do to have the tab or phone release the old settings and take on the new ones. Hope that is a clear enough explanation of my problem. Thanks for any help offered
Is this a one time thing or does it happen often? Are you rooted? rom?
Both phone and tablet are stock, no rooting done to either. It happens regularly, today again in work it happened. Had to forget the connection and reconnect several times until eventually I was able to connect to internet. Really annoying as it shows as wifi connection is strong at all times.
ps some additional info.
I had used the tab tethered to my phone in work to show case how good the tab was. I can get intrrnet connection no problem on my phone, the tablet shows it is tethered to WIFI hotspot, just when i click on an internet link, no page appears. It annoys the bejeezus out of me cos i know it should be simple. I even tried bluetooth tethering and it wouldnt work either, when it did previously. What i am thinking is that i had juice defender on both my phone and tab and recently uninstalled it as i had read there was no real benefit in using this with ICS. I am wondering if it has possibly screwed up some setting or other in the phone or the tab, i.e. maybe set something and then when i have removed the program, it has not reset something, yes that sounds pretty vague i know. Anyway, thanks again and thanks for any further suggestions. p.s. i may try reinstalling juice defender on both devices to see if it makes a difference.

I don't know if his will work, but, instead of tapping on the connection and hitting connect button, try pressing and holding down on the connection until a menu shows up. Try connecting from that screen.

You said both are stock and unrooted?
I would try rooting your phone and freezing tethering manager. If i recall right if tethering is not allocated on account, i beleive that the carrier can disable tethering through that app,i could be wrong but it may be worth a shot.
Or your could try a tethering app from the market, like PDA net or the tethering app from CWM also there is a tethering app on google code website.
let me know if that helps
Try Bluetooth tethering instead.
Edit: re read your post.
Try forgetting, the re-pairing the devices. It took several tries for me, or try fox-fi for your phone, and PDAnet for the tablet.

I had also removed avast virus protection as well as Juice defender from the tab. It seemed to be shortly after this that the problem arose, it may be a coincidence but i thought it may be some setting or other that had been changed. I hard reset both my phone and the tab but the problem continued.
In the house i could connect to my home WIFI everytime without issue, then if i tried to tether to my phone it would not connect. I would jump between one connection then the other and eventually it would connect to the phone.
Anyway, thats the history, now to what is happening now. The other day i read somewhere about putting tab in flight mode before tethering, so i tried this and it has worked first time every time since, so i am hopeful this is a permanent solution. What does surprise me is that the tab is not a 3g tab so i would not have thought putting it in airplane mode would make any difference but, hey it has so if anyone has similar issues it may be worth giving it a try. Good luck.
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! ))

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

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.

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 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.
