[Q] Wifi slow, 3g fast, any ideas why? - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

hi all,
Something has been bothering me for a while with my p6800, when connected to wifi my connection intermittently slows down to a crawl or even times out, taking forever to load a webpage. No problems on 3g though... My wifi connection is not disconnecting or anything, full bars all the way.
Anybody know why and how I can fix this, as annoying is an understatement
Thanks!
Ps. using 300n router, not a congested channel. No problems with wifi on notebook or other devices. On Android 4.1.2.

Hi Arobase,
Thanks for your reply, had just about given up on this one. :good:
I'm on 4.1.2 stock md3 and using WPA2 encryption. Don't think it matters though because I've had these problems from the get go, on stock ROM when just bought and on various Wifi encryptions (random browser timeouts, no Wifi connection drop though...). Can't really see a pattern, sometimes my wifi will work flawlessly, other times it just refuses...
Was wondering wether others had a similar issue. If you've got any ideas, do please let me know. Tbanks again!

WiFi is slow and unstable!

Hey!
Just got my Touch Pro! Love it, except on thing.. When im connected to my wifi-network, it seems very unstable... Try to load up a web page in Opera and it takes forever.. suddenly it may work, but shortly after its slow and sometimes it doesnt work at all
Same goes with Youtube, so Its weird.. Anyone got any ideas?
Cheers!
You haven't mentioned what kind of signal strength you're getting. Tap the wireless icon at the top of the screen and it will tell you.
99% of problems with Wi-Fi are purely down to poor signal or interference from other Wi-Fi sources. If your phone can see lots of networks in your area, you might want to change channels on your Wi-Fi router to help avoid interference from the other networks.
I doubt the problem is with your phone.

Captivate WiFi issue?

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...

[Q] Wifi keeps dropping off?

Hi all
Does anyone else have an issue with their wifi where it looks like its connected (blue wifi logo etc) but that it doesn't work? (ie can't browse, emails and twitter doen't refresh etc)
You can 'fix' it by turning wifi off and on again, but then a few minutes later the connection has gone again?
It is not a signal strength issue as it happens next to my router as much as upstairs, away from the router.
I've moved router channels to a less crowded frequency but to no avail.
Does anyone have any ideas?
I have a rooted .29 if that helps?

Same here but on the. 17 version I think....
Possibly not a great deal of help, but I just took mine back and the new one is perfect. No one else seems to have any problems so I assumed it was a hardware fault.
No wifi problems on mine. Using a Netgear WNDR4500. Range is excellent, much better than any of my other android devices.
Works like a champ! rooted .26 :thumbup:

[Q] CM11 WiFi problem

Hi,
I'm on 11-20140804-SNAPSHOT-M9-ville, official (HBoot 2.15), Radio 1.35a.32.45.27
I have a strange problem with my WiFi. I can't really tell what details are important, so I'm gonna give you guys the full story.
After rebooting, everything works fine and the phone instantly connects to my WPA2 PSK secured WiFi at home. When I'm at university during the day, I'm connected to another WPA2 WiFi (maybe some of you have heard about "eduroam", TTLS/PAP authentification), which also works fine. However, when I get home in the evening, my phone won't connect to my personal WiFi at home any more. I see the SSID, but when I try to connect, it says "Connecting..." for a milisecond, then just jumps back to showing me it's a WPA2 secured WiFi without having done anything. I get no error message or anything, it just doesn't connect and doesn't even seem to really try to connect.
When I reboot the phone it instantly works again without a problem.
Any ideas? Are there error logs for failed WiFi connection attempts anywhere for further analysing the problem? Any hint is appreciated!

Hi,
I had exactly the same problems with m8. I have a Virgin Superhub 2 at home which broadcasts on 2.4 and 5 Ghz. After disabling one of these frequencies, the behaviour briefly changed. Then went back to not working. With eduroam all worked nicely.
I read somewhere that I should activate the "Scan always available" setting. Sadly, I didn't get a chance to try that because I was so fed up with
- the significantly lower sound on CM (is that something you experience with radio 1.35a?)
- mobile signal drops
that I wen back to Maximus 10 where I have no problems at all.
I had radio 1.15 and 2.15 HBOOT when I had those problems. Now I'm on also 1.35 with Maximus 10 and problem free but would like to return to CM if the low sound problem and the WiFi problem could be sorted out.
Here's an interesting little detail I noticed: When I stand right next to my router (full WiFi signal strength) and click on my WiFi and choose connect, the signal strength drops down to one bar immediately. Also, the eduroam network changes from "not in range" to "disabled".
Playing around with the WiFi options didn't help.
edit:
What exactly do you mean by lower sound? That the phone's maximum sound volume is lower than normal? That's something I experienced on my old htc desire, but not with my htc one s. Also mobile signal seems to be stable, no signal drops. The only thing I found curious is that with activated mobile internet, it often changes between 3G, H and H+, but judging from google search results that seems to be normal or not connected to the custom rom.
went through the CM bugtracker, apparently it's a known issue without a solution
https://jira.cyanogenmod.org/browse/CYAN-3923 if you want to know more
One last question, maybe someone here can answer it: As far as I understand the issue, it's a problem with an old WiFi driver and the corresponding kernel modules.
Wouldn't this issue then be present in all ROMs which don't use the stock kernel? Or did I misunderstand something?

Same problem here with Miuri. Tries to connect and then gives up.
The problem has been resolved by the CM11 devs. I'm running nightly 20140819 and it's working fine now for me. :good:

WiFi issues after Marshmallow update

Hey guys,
Having an issue with WiFi since the Marshmallow update. We have an open WiFi network at work that you need to sign in to the firewall to access internet. Previously it worked fine, but after the Marshmallow update, my phone constantly drops the WiFi network. It always happens when I lock the phone or otherwise let the screen turn off for more than about a minute, but it also happens even when I'm using my phone, if I'm on for more than about 5 minutes on average it drops the network. When I go to reconnect, it lists under the SSID "Internet not available" but I just tap the network and tap connect and it connects anyway, doesn't even make me sign into the firewall again. I'd really appreciate some help with this, if I can't get this fixed I'll be doing away with Android for good. I don't use my phone for much other than Facebook and games, so I'm not at all opposed to using a custom ROM if that would help. Just haven't installed one since CM7 on my HTC Evo Shift, so I duno which would be best for my situation. Thanks in advance for any input!
Bump. Hopefully someone has a solution...
One more bump before I give up...
Hi, I'm on stock firm, and after the last upgrade, I cannot connect to my work's wifi network. It's a EAP-MSCHAP2 connection. At home, wifi works flawlessly....

try talking to your system administrator at work. The upgrade may cause a comparability issue that maybe fixed by a simple tweak at work.
