How do I fix my wifi? - General Questions and Answers

I have a Galaxy S5 Verizon.
Starting today, my wifi on my device has been acting stupid.
Whenever I try to browse the internet, it lags. It isnt an issue with my internet or my router because when I run a speedtest on my cellphone, it will take a minute to start but when it does start, i get 11 ms ping 60 down 10 up.
Same with a wired connection on my desktop. Same on my galaxy tab 12.2. They both achieve these speeds. Except they don't take forever to start.
I noticed that when I use wifi on my phone, the wifi download icon is active, but the upload icon isnt. Meaning when I use wifi to browse the net, its able to download data using wifi but it stalls trying to uploading data.
Well because of this, instead of having my normal instant speeds, I have lag. It takes a while for a youtube video to load. It takes a while for a web page to load. WHen i used the app store it took a while for the app images to download and it took a while for an app download to initalize.
I dont know why this is happening. All I know is that for some reason my device is failing to upload data using wifi right away. It always stalls.
Like I said, this just started happening today too.
I didnt do much on my device. The only thing that could possibly have done something is that I used terminal to change my device hostname. I was tired of seeing "android-3478547583gf7348574835" On my router arp table. So I went onto terminal and I did
> su
> getprop net.hostname
> setprop net.hostname <new_hostname>
And then I went onto recovery and wiped my cache.
Thats the only "Technical" thing I've done with my phone today and now for some reason my wifi stalls.
Any ideas?
I wiped the cache again to see if that would fix it. Didnt. Rebooted my phone dozens of times. Did nothing. I dont want to resort to factory resetting but I will if I have to. Im rooted. GS5 on 5.1.1
I shouldnt say its a lag issue since I still get 60 mb download speeds. Its just that the wifi on my phone is failing to initialize a full connection right away

Download issues

Currently having some issues downloading some videos my wife sent me. First off, I am currently out of my country of origin so I've already had a few hurdles to jump over to even get the ability to download. But once that was taken care of I haven't had issues; until now.
My problem is mainly that since this morning, I haven't been able to download anything she's uploaded to hotfile.com for me. Each one of the three browsers I use have different issues. Skyfire automatically goes to File Download Complete and obviously the file won't open because its only 280b/43Mb. Opera 10 freezes loading on the /get stage. And IE just thinks the rerouted link doesn't exist.
One solution I've had is hooking my phone up to a laptop and running the Internet Sharing program. It works, however, I am not able to stay in the same location long enough to monitor it and make sure the internet connection doesn't drop. So more often then not when I get back to it the connection is reset and download interrupted.
I've tried connecting to both of the networks in my area, and same problem on both networks. Also, I had my wife verify the file is still there, and on her end she has no problem.
Any ideas? Much appreciated guys.

[Q] Strangely isolated WiFi issue

Hi all,
Captivate with Cognition 2.2B9.1.1
Android 2.2
Belkin router (it is at home so I can't get the model number right now)
The simple problem is that my captivate will connect to all of the other wifi networks that I use but it stopped connecting to the one at home. All other phones and computers in the house connect just fine. The interesting thing is that when you watch the connection status on the phone, it connects and then immediately disconnects and starts the handshake over again. I have watched this happen over and over again. Weird.
I first thought it was my router so I modified the settings by using different channels and security methods. No dice. I then reset my router to factory specs and still nothing. I want to blame the router but I am stuck thinking that it might be the phone. Is there a way to purge the WiFi and IP information? I would rather not dump my phone and restart if I can avoid it. Can this be done through a terminal app like other platforms?
Any ideas or similar experiences?
Thanks ahead of time.

So I dropped an updated Cognition Rom 2.3.b6 and solved the issue. Last night I cleared my RAM (level 1 and level 2) and when I got home the problem occurred again. Bizarre. Could I be clearing a cache that refuses to refresh? Ideas?

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?
I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.
Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.
I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?
Fully charged. It even happens when pluged in with the charger.
My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.
Would you guys having this problem also post it here?

Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.
Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.
Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again
I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.
same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone
How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.
Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

Loosing connection to server...

Rogers I896, No Sim, Only Wifi. Rooted. Stock ROM.
Yesterday my captivate lost connection with the server. I have a nice connection to wifi, but can't get anywhere. This happened once before. Market gives me "Unable to connect, Retry" and adding an account to the device gives me an "unable to create a reliable connection to the server, try again later..." kind of message (I don't recall the exact words). Browser and Email, just can't get anywhere.
Reboot makes no effect.
Deleteing browser cache/reboot makes no effect.
Ran FXR Wifi fix - no change.
My Galaxy Tab and PC are connected to wifi and can go where ever they want, so it isn't the router.
Last time I did a factory reset and carefully installed just apps and data where it wouldn't affect the connection. This restored my ability to connect. This time I just did a factory reset, installed Titanium backup and restored all apps + data. ...and I can connect just fine.
What killed my connection on my Captivate? How do I keep it from doing that? This wipe and restore is getting a bit old.

Bump, I have been having the same issue. It continually loses connection every few seconds then i have to go back to the main talk screen to reconnect. The app is basically useless at this point. Anyone else experiencing this issue??
Me too with apex 11 b3

Data connection keeps stopping - Three UK

Over last few weeks i noticed that my data connection keeps dropping and i cannot connect to any website or anything.
I happens probably once every 10-20 mins but it shows i have full bars and H sign still there but nothing will connect or my tv streams stop working etc.
Only way to fix is either reboot or switch mobile data off and then back on again and then it starts working again after a minute or two. Its driving me crazy because i cant watch any live tv or browse the web properly.
Im stock rom not rooted my phone or anything - any help would be greatly accepted.
Ok i dont want to jump the gun but i found this post
http://forum.xda-developers.com/showthread.php?p=49148699
The user said to change APN setting MVNO to IMSI so i thought i would give it a try.
I have been watching TVCatchup now for 40 mins without a single hiccup!!
And like user said it seems faster than ever now
Any idea what changing this setting has done?
Will i wake up next month to a ridiculous phone bill or anything even though i get unlimiited data??
