Hey everyone. I’ve used this site coupled with androidforums for all of my Vibrant problems. In the past I have found all of my answers with a quick search. Unfortunately I have run into a problem where searching hasn’t yielded any possible fixes.
Get ready for a novel. (or scroll to the bottom for the tl;dr)
I updated my Vibrant to 2.2 a few days after the release was updated. I’ve been tethering my phone pretty frequently since then. I rooted my phone days before, didn’t screw around with anything while rooted, then unrooted before I updated. I’m using Windows 7. Using an unlimited data plan. My usual download speeds (through speakeasy) were around 1.3mbps. Uploads were slower, but they don’t matter much anyway. The connectivity and speed have been great up until last night. I was doing some school work, downloading various word files when all of the sudden internet pages were loading extremely slowly, and all of the downloads stopped. I saw a little yellow ! yield sign over the internet connectivity method in my task bar. It said “No Internet Access”. I switched to wifi (my phone tethers 2x as fast as the wifi here), and continued. School > phone internet problems.
Wifi speed (speakeasy.net) (today)
Down: 0.44mbps
Up: 0.10mbps
After getting home today from class, I finally had a chance to try to see what was up. I plugged my phone it, and it worked pretty well for a few minutes. After those few minutes the yellow ! came up, paired with “No Internet Access”. I disconnected my phone from my computer, tried again, reset my phone then tried again, and even removed apps that ran in the background that were sharing the connection. Nothing changed. My phone has been in the exact same position on my desk each time I have tethered it, starting from the very first time, always on the windowsill.
I downloaded the speedtest.net app to see what my speeds were, because the wifi at my house was loading pages and stuff a lot faster than my phone was. While remaining somewhat precise, the results were all over the board. While doing the tests I put the phone in its usual spot on the sill, and then moved it directly in front of me on my desk. I started to search for related problems on line, but couldn’t find anything more than a thread or two with the answer to a similar problem being tower quality/relative distance.
I ran the troubleshoot app that windows has, and it came back with “The DNS server isn’t responding”. Again I searched (google) for a possible fix, and yielded no results. The only thing I found was some custom DNS servers mod on here, but I’ve been waiting for Kies to download for the past 20 minutes to back my phone up. While downloading Kies I noticed that I was getting ~25kbps, and that it was going to take 30+ minutes. I hooked my phone up, and restarted the download. It shot up to 5mbps then just dropped. It went from 5mbps, to 4mbps, 2mbps, 1.5mbps, 900kbps, 800-700-600-500, all while the rate of change was decreasing as well. The jump from 5mbps to 1.5mbps was by the mb, but once it got to 900kbps the rate of change went from dropping hundreds, to dropping tens, to quickly dropping ones, to trickling out single kilobits. Then I was hit with the ! “No Network Access”. While this was happening the phone stayed completely stationary. The complete loss in data came only after tethering. I browsed the internet on my phone for a few minutes after, and everything was fine. It’s almost like the data tethering is signaling the phone to drop network access or something. I have zero apps running in the background of my phone that are using push, to my knowledge. I’m at a loss.
The speed tests I did earlier are below.
Tether speed (speakeasy.net) (last week)
Down: 1.3mbps
Up:??
Today’s 3G speed (speedtest.net app) – based off of 19 tests done in a little under an hour.
Highest download – Lowest download
Down: 0.86mbps - 0.06mbps
Highest upload – Lowest upload
Up: 0.62mbps – 0.03mbps
-Actually the lowest for each was zero, after getting the “No Network Access” I disconnected and tested, and got -0.00mbps.-
Average:
Down: 0.41mbps
Up: 0.18mbps
Also, before buying this Vibrant I had an iPhone on Tmobile. I unlocked it myself, jailbroke it, set up tethering , ect, ect. So I’m not completely phone-modding illiterate. I've just been out of the loop for a year or so.
Tl;dr – Been tethering phone for a month with consistent speed/no problems. Last night randomly I got “No Network Access”, and since then my tethering has started at a very high speed after plugging it in, then dived down until there was “No Network Access”. Windows 7 says “The DNS server isn’t responding.” Phone was in the same spot it has always been in, everything has been fine up until last night. wat do?
Maybe you have been throttled by Tmobile. Have you gone over your cap of 5gigs? Our data plans are not truly unlimited, but you atleast you have received a text from Tmobile first. Thats my guess.
i sometimes have a similar problem but it sounds like youre tethering via usb, correct? I use mobile ap to use the net wirelessly off my phone and have had issues with it either not connecting at all and giving an error or just never connecting. My solutions have been quick easy fixes and figured id share but not sure if they would work for you or not. When it gives the error in mobile ap i simply click settings and then save (not changing anything) and then turn it on again and bam it works... When i get no connection after it works, or if i lose connection while online, i flip the phone to airplane mode for about 45 seconds and then turn airplane mode back off and turn mobile ap back on and everything is great. I also have the "unlimited" data, and i use it a lot, actually 3 days ago i looked and was at 4.7gb used... and havent looked again but i gotta be over the "5gb limit" and i havent been throttle capped at all.. Everything is running great speed wise... figured it would be worth a try if you wanted to, like i said, not sure if it will help your situation but just in case it might thats how i get around the data drops.
Hey guys I am loving my atrix so far, I upgraded from an HTC Evo. I am having one weird problem and I haven't seen anyone else post a similar issue. I connect to my wifi network fine. It uses WEP encryption and it's the standard FIOS router that verizon supplies. I never drop connection but when I download from the market it takes unusually long as if it isn't using my fast wifi connection. My GF who has the nexus s is connected to my network also downloads much faster off of the android market. It feels as if even though the atrix says I'm connected to my wifi network it is still using the 3g data speeds. I tested it with speedtest and i get 16000kbps down and 7000kbps up. It sure doesn't feel like it though. Anyone else having this same issue???
I am having this exact same issue! FIOS, Verizon's default router, WEP encryption, and the speeds are slow only in the Market.
I wonder what the problem is...
I just tried WPA2 encryption. Same exact problem. I'm getting speeds of around 250 kb/s, even though the speedtest.net app shows me getting around 2.5 mb/s.

That is my exact problem also. I wonder what is going on here.
I still haven't done anything to the phone like rooting it, so that can't be the issue.
Somebody did suggest I try changing the radio channel on my wifi router to 6 and 11, which did nothing to help the speeds.
It's strange that this is ONLY happening with the Market. Anything else internet-based works at regular speeds.
I wonder if this is only an issue with FIOS, or with the standard Verizon router? I'll be able to try out other wifi networks tomorrow.
Just curious, but have either of you with issues tried to push an app to your phone from the market website? It probably won't help, but worth a look.
Nope, just as slow as from the Market app.
Man, I have like 60+ apps to put on my Atrix. It'll take me hours to put it all back with these speeds. :\
Here's another problem: even on 4G, with a full signal, I load webpages with flash elements in seconds, but I download apps just as slowly as I do on wifi. It's like my Atrix is deliberately being capped, and ONLY with downloading apps, no matter what type of data connection I'm on.
If you use a different wireless network (something open and public) does the speed still seem slow?
Yes. 3G, 4G, wifi, it's always capped to around the same speed.
and again, it's ONLY downloading apps from the market. Absolutely nothing else.
Bandwidth usage while downloading a package from the market.
Bandwidth usage while streaming from youtube.
Monitoring done from my wireless router.
Did a bit of testing. Maybe some others can do the same to verify. I need to get ahold of my ISP because I am not getting my advertised speeds but download speeds from my computers were higher than my phone. I downloaded Astro File Manager and downloaded a .zip archive to the phone as well. Speeds did not seem throttled like they did when downloading from the market.
Just received the monster, same issue here!!
Using it in Germany. Very slow speed on my Wlan, sucks. I'll be anxiously following any news.
Could Google have purposely done this to the market?
http://forum.xda-developers.com/showpost.php?p=11760852&postcount=7
someone try this and see if it works?
...actually, couldn't somebody just remove their SIM card and connect to the market with wifi? I've got a full body case with a screen protector on mine that I don't wanna screw up, but could somebody try that?
EDIT: Yeah, that didn't work.
Well just went back to ATT and got an exchange hoping that I just got a bum unit. Unfortunately same problem. On top of that I have noticed that my 3g data speeds are even slower now!! Speedtest will yield 500kbps down and 50kbps up WTF!!!
Replace it again. It's another defective unit. I've asked a bunch of people, and that's definitely the case.
Great. I checked the manufactured date on the phone in the store. 1/11/2011.
It was defective. Damn it.
So I'm basically playing roulette each time I exchange the phone.
I wish a firmware upgrade would fix the issues. I am in the same hell.
Last night I was looking for a video on youtube on my photon, and my wife was searching on our old laptop. Both were connected to our WiFi router, and we were sitting right next to each other. The laptop was MUCH faster than the photon, and the photon kept hanging in the middle of videos.
I'm pretty sure it was a wireless issue. I turned off WiFi and ran it on 3G, and it ran faster with no signal drops! I went back to WiFi and the performance dropped significantly.
Any suggestions for how to improve the WiFi performance? Would a newer router help? The 2300 is tried & true, and I've always like it. Does WiFi channel matter? Other ideas?
I'm not rooted, if that matters for any response.

What build version are you currently on? Have you flashed any of the updates or is the phone stock from Sprint?
I don't think a new router would help. My wifes nexus s 4g always has better signal strength than my photon when on wifi, I compared it to a friends Htc sensation connected to the same router and he had the better signal strength, and places where my evo 4g use to get a very weak signal but was still able to connect the photon won't connect at all.
Just some info to add to the OP....
I have a good router at home and a good one at work (different brands) and my WiFi is fast and smooth while at work but sometimes at home it is slow and chunky. Very sporadic at home for some reason and it never seemed to happen until after one of the updates.

I have the same issue after the last "update". It seems to lose the wi-fi connection and keeps any network from connecting. I have to turn the wifi off and wait for the 3G to connect or I won't get any mail. I can't figure out what changed, but it used to work perfectly. I'm contemplating rolling back to the first update.

I have installed all OTA updates to date.
Build No. 4.5.1A-1_SUN-154_6
Ok, I bit the bullet and used RSD to roll back to the earliest version of the code (I didn't lose any data or even the location of the widgets on my screen) and it totally fixed the WiFi issues I've been having. Plus the battery seems to last quite a bit longer. I thought that the latest update was a loser, this just proves it.
I came to the conclusion on my own that the photon doesn't like any mixed wifi signals; i had my 2.4ghz router running with mixed b/g/n for wireless and it didnt play nice. Once i changed it to n only it worked way better.......

I am experiencing the same wifi issues after updating to 198_6. Which version did you roll back to?
I would be interested in knowing what version also,, I'm sure if I did some research I can find out on my own in the meantime,,,,

Sorry to be so late responding. I've been away from the forum for awhile (been out slumming with the iPhone crowd trying to see what the panic was about).
1FF-sunfire-user-2.3.4-4.5.1A-1_SUN-154_5-CM-release-keys-signed-Sprint-US.sbf
is the one I used. I just accidentally applied the OTA update and the WIFI issues returned. Back to the drawing board. I guess I need to do the "no OTA update" hack.
EXACTLY! This has been happening to me now on TWO Phones! I can't say that it's been just my home router though. I took my phone into the sprint store, hooked up to their wifi and same problem... Right off the bat it didn't connect to the market.
This happens at home and is super frustrating. I will get to browse a couple pages/apps/zedge then nothing. I've even had it go retarded enough to pop up the 3G icon as well as the wifi signal indicator...? No up/down arrows showed in the 3G to indicate data transfer but I was just like WTF?
So now when I leave my house, out of range of wifi, my phone blows up with e-mails, apps I've had in queue, etc.
I've noticed these problems more with the most recent update but I didn't spend too much time browsing without it though. Maybe I'll get a new one from Sprint and just never apply the update.
**EDIT: Both times I've received one of these phones the only update I've done is the most recent one. I haven't bothered checking the software version they are coming with. Is it possible they're no longer putting out the first update and these aren't cumulative? Just a shot in the dark but maybe I needed that first update before the second to make things jive. It's unlikely they would put out updates in this manner but I'm grasping for straws here.

My experience is different. The phone connects and works great at the office but not so great at home. Both routers are set on mixed. Not sure what the difference is (besides the brand of router). I do know the one at home is handing out IPs but the one at work is not. The server handles that.
Not sure what else could make a difference.
Just got my third Photon from the sprint store and same issue. This one already had the 42.5.7 update installed on it but wifi has been flakey. I'm convinced that it's something in the software combined with the wifi we are using. The ridiculous thing is I have a motorola SBG 900 that I use for wireless at home so you would think they would be compatible. I really like the phone otherwise so I hope a new update is right around the corner.
Just went and bought a $160 modem/router combo and my phone has no issues at all with wireless now...
Three Photons in a week and a good chunk of cash later and I can use wifi at home. And now that I've finally had time to play with it I find out wifi tether only does ad hoc natively.
I wouldn't mind having my Evo Shift back.
I'm having the same problem. I updated to 198_6 as part of the testing group and at first had no problems with Wifi. Now when I am connected to wifi (both at work and at home) I can't send or receive text messages, download from the market, nada. As soon as I connect back to 4G everything works perfectly. I'm gonna roll back tonight to the previous update. BTW, I also updated my PRL to 51082 and that didn't seem to help.
Is the problem basically where wifi is connected to the router then stops going past that? Like you still have an ip but no data?
If so try turning off notifications for gmail or turning off the "notify once option". This seemed to help me lose my connection to where i had flip on/off the wifi radio.
Let me know how you fare with this.

Are you running any "turbo or super G" like modes set on the router? I remember reading on the motorola forums that these sometimes may cause issues - other things, router firmware update if applicable... do you have an airave device? If so, make sure the distance between that and the router are more than 5ft apart in distance.
Still, in your situation - streaming over the wifi shouldn't be an issue with bandwidth to keep in consideration, but realistically speaking - that should be better than 3g speeds for video playback.
These were some of the thing I had picked up from while troubleshooting an ongoing issue I am still having with my old d-link di-624 and photon getting stuck at "obtaining an IP address" on the official Motorola photon forums. In the latter situation, mine will connect if I reboot the router... my other tablets and laptops connect flawlessly on this.
Hi,
got my SGS3 today and started playing with it. I started downloading my apps and during this the wifi dropped connection 3 times. It connected again within seconds, but this is not good.
The distance from my router was around 3 meter. My SGS1 never dropped connection.......
Any idea's?
I also have problems with wifi:
It connects normally but after tens of seconds the connection is dead. Android says still it's connected, but it simply doesn't work.. I have no sim installed atm because I have only an oldskool sim and not a micro sim. Tomorrow I will get a microsim at the vf shop and test again..
I had issues like those aswell today using my Adam but only with wireless. Weird ?
Probably your router problem? I'm sure reviewers would have identified that issue as well. Can't wait to get mine though, hopefully mine don't have the same problem
Htc hero, sgs 2 and three notebooks are working fine. Tried different router configs.. Nothing helped. Today i receive a 2nd sgs 3, so I will put it on the test..

I have a similar issue, the status bar shows wifi is fine (the arrows are blinking) but no actual data on the phone. Checked on my tf201 on the same network and its working fine.
This has happened twice now and only restarting the phone fixes the issue.
I have downloaded over 2 Gb with my SG S3 over Wifi at home and at work. No issues, and it´s super fast, even beating my XOOM.
I have a Dlink 625 at home and at work we have a Cisco something.
However had a different problem where the phone just restarts when dialing a number, and then it boot looped on the logo for about 5 times before starting up. scary .

This is the same problem I was talking about, but rebooting does not work for me..
Mine seemed to behave a little like this to start with also - I changed the Wifi Frequency Band (Settings-WiFi-Advanced) to 2.4ghz only and its been rock solid since.

Yes, it is in b+g+n mixed mode and is saying 2.4ghz. As a matter of fact I'm not able to chose another frequency (maybe because of the b and g). I can try to put it in b/g or g only mode.
I also read about that NFC's RF signals can interrupt the Wifi signal, so I will try also to disable the NFC option.
I tried another galaxy s 3 with the same settings.. that one works well on my wifi network.. I think the wifi module is not working properly..
Do you have by coincidence a draytek router. I have the SGS3, and my sister has the SGS2. We both experience problems with wifi also here. I have several draytek routers, all giving problems.
It seems to become a bit more stable if you set the Channel width to just 20 MHz, in stead of 20/40MHz. And use WPA2 only, not a mix of WPA and WPA2.
These two changes made the connection a bit more stable for me, but i'm not 100% convinced yet.
mine doesnt hv any issue with wifi, but for my cell signal, it changes between 3g <> h <> h+ alll the time, anyone too?

I posted a solution for this in the known issues thread but I thought I'd repost here in case you missed it.
I was having similar problems but found that if I disabled the Wifi Power Save Mode I was back to blazingly fast speeds and no dropped connections.
I had to go into Service Mode (dialling *#0011#) and hitting Menu => Wifi and turning off the option for power save mode.
Give it a try. It fixed a couple of other guys problems as well.
Am giving this a go will report back.
That worked but battery drainer . Have put it back on and set wifi to off when screen off. That has helped loads.
Worked for me too, and trip really is unnecessarily complicated and hidden to get something that should be working out the box.
Issue started today. I got my phone a couple days ago and speeds were perfectly fine. When I turn off wifi and use my 4g lte, speeds are blazing fast. But to save on data bandwidth, I like to stay on wifi. When I'm downloading stuff from the playstore, my speeds are insanely slow. Browsing, youtube, streaming, everything else works at normal speeds on wifi. Speed tests are normal also.
Is this at work, or at home?
My wifi at home is actually faster than 4G.
If it's at work, it could be that your IT Department is doing traffic/packet shaping to the Google Play store. We don't even allow access to it on our internal network.
Might be the general WiFi disconnect/reconnect problem that a number of Galaxy S III owners are reporting on the boards, such as me.

ill have to wait to get off work to test the home wifi. but the problem is at work. no issues with throttling, cus i control the router settings at this place
worked fine yesterday, and today i noticed speeds are crippled. device connectivity isnt an issue.
