[Q] Wifi Issues?

After reading a bit it's seems to be a common issue on ICS and later. My device occasionally looses it's wifi connection, at which point I have to go to settings and turn the wifi off and on. Is there a better solution to this problem? My router is using WPA2-PSK and is on channel 7.

Wifi seems to stay on fine here, but I cannot connect to 5ghz, only 2.4ghz. Not sure if this is an issue or if the Wifi chip only supports 2.4 ghz.

it doesnt connect to 5ghz, unless theres a trick to it??? but use wifi analyzer and look for the strongest channel on ur wifi router to fix ur problem

Turn off multimedia support on your router if all else fails

Yea I'm having trouble as well. I have a telus smart hub at home and it is super slow. Then when I use my hotspot on my Gnex from rogers, it runs fine, although this app takes awhile to load.
Tried playing with the settings, only think I couldn't find was the 5ghz and 2ghz.
Try some more playing tomorrow and look for different routers

Can I ask someone with nexus 7 to check if it connects with wifi AD-HOC network without problems?
I use my old LG gt540 as a 3g modem + wifi router, but it works only with ad-hoc. For example my HTC Sensation can't connect to such a network.
edit: NO, it does not connect with AD-HOC

I had the same problem, repeated on two different GS4 phones today. I tried everything possible to figure out what was wrong but couldn't fix the problem. The phones would connect to my wireless router, but would send and receive data only intermittently. Sometimes, resetting the router, or pulling the phone's battery, or going into airplane mode would be the only ways to get the phone to actually send and receive data, but it would only work for 20 seconds - 3 minutes. Every other wireless device and wired device works on this router, except for the GS4. And the GS4s both worked in-store on their wireless network. My guess is that it's a hardware or software compatibility issue with certain routers. Oh and mobile data worked like a charm.
What kind of wireless router do you have?

Maybe you need to pay your internet bill

My S4 has the exact same problem on a DLink 655. Works ok on other networks I have tried but on the DLink it will work for about 20 seconds and then data stops flowing. No other device I have has any issues.

To figure out whether the issues is the SGS4 or the SGS4<>your router you really need to try it from some different locations. The i9100 had tons of issues with D-Link routers so perhaps that's what's happening here. My solution when I had issues with my i9100 was to ditch D-Link forever and move to NetGear and I haven't had a problem since (at least at home).

Hey guys my at&t S4 16 gig is having the same problems. For me it connects to my d-link 615 for about 2 or three minutes then times out. I have to turn wifi back off and on again for my wifi to kick back on. I'll do some more testing on other routers to make sure its not my s4. Hope its my dlink. If so ill get a none dlink router. Frustration as all hell.. I even connected using pin code and still the same any suggestions guys Thanks. Really don't want to return phone. Thanks

My router is a DIR-655 as well. Looks like this may be an actual issue with D-Link routers? Anybody having issues with another brand of router?
And if it IS an issue with D-Link, who's at fault for the problem? Samsung or D-Link? My 655 has been the most reliable piece of network equipment I've ever owned. It works with everything, except for a Galaxy S4...this is annoying.

glad i still have my unlimited data plan. no real reason to click the wifi button... most wifi spots i go near are more bogged down & slower than the s4 lol

yeah i actually got my phone 2 days ago and right out of the box had this problem, i was on other sites saying that the s3 i900 had alot of those issues on 4.2 and 4.2.1 jellybean.. lots of users reporting that when the upgraded to 4.2 ect they started having those issues.. i hope its a jellybean issue not hardware issue.. i agree with you though i have had my d-link 655 for years and never had an issue till now.. i have my s3 and iphone 5 all running on my dlink just fine S4 not so much..

Same problem here - excelent connection at 150 Mbps with my dlink dir-855, but dies quickly. wifi toggle helps. Tried a lot of settings, fixed ip/dhcp, 2.4 / 5 Ghz and etc - problem persists.

i have TP-LINK router but i drained my battery till phone went off then charged till 100% and no issues so far wifi works fine... just wondering why this problem could appear...

Seems like I've found the solution - in router settings, in firewall section disabled "TCP Endpoint Filtering" (set from "Address Restricted" to "Endpoint Independent"). Have not had any issues since than. But can't actually tell if it puts the network to any risk compared to previous settings.

i have also different problem
everything seems good but i have a big problem with wi fi but
when i try it with s2, it is working
whenever i want to access internet with wi fi on s4, in Wi fi menu, it writes -----> in order
1) "Obtaining ip adress..." and later
2)saved,secured
3)Obtaining ip adress...
4)failed to obtain ip
5)newtwork disabled becauseinternet connection is low

Samsung galaxy s4 wifi issues
I have the same problem, seems to be a wifi issue with 4.2.2, my router is DIR 655 Dlink, wifi only works if I just connected it then its either slow or disconnects. very frustrating, also I get 3G but its slow.

A family member just got a S4 and is facing the same issue with the DIR655.
I've updated firmware to latest version for my A4 hardware model, version 1.35ww but the problem persists. So I had to bring out another Access Point (TP-Link TL-MR3020)to cater to his needs...
So who should we complain to? the DLink has been serving me faithfully for the past 3 years+, infact the DIR655 was one of the best wireless routers around and I never an issue with any of my wireless toys, until it met the S4...

Can you confirm that this fix works for a lengthy period of time? Is it still working? I thought I had fixed mine once (the phone was working for a while) and then it just stopped transferring data altogether. I think tinkering around with some things can make it better or worse, depending on what it is.

Same here. I was contemplating replacing my 655 after 6 years of service without ever having to reset it only because it will not pass magic packets from WAN to LAN...at least the A versions don't (I have A2). And this is becoming more of a frequent problem as of late. Every other device connects without issue, even my mom's S2. I'm on WiFi right now on my HTC Vivid...no problems.
Which brings me to this...everybody in this thread with a 655, please list your hardware version and firmware version. It can be found at the top of the router's web interface page.
Mine is..
Hardware Version: A2
Firmware Version: 1.34NA

Please Help...
P.S im not rooted

Stock Android does not support WiFi direct. It uses bluetooth to transfer. I would try the Superbeam app (You have to install it on both phones). Are your other phones working on the 5GHz WiFi band? If so, what channel is your router broadcasting at? Some people have issues with the Nexus 4 not connecting to bands 12 and 13 (if my memory is correct), but not all (My 211k Nexus is fine). Are you running stock? If not, what ROM and kernel are you running? Have you tried to disable WiFi optimization (Settings>WiFi>Menu button>Advanced>WiFi Optimization)?

I recently moved to another location and found out Nexus having hard time to connect to Google through Wifi(grey wifi bar appears often). Surfing internet is also dramatically slower than before. I do not know if it is Google I/O related issue (namely software issue) or router (namely hardware issue)?
All my PCs and another Samsung Android phone work fine with the new router. What's happening?

Wifi Connectivity Issues

My new galaxy s4 I9500 has been working fine until 2 days ago when the wifi started reconnecting every few seconds. I'm not sure what the problem is and I cannot find a solution for this. I have read the issues with the D-Link routers however I use a Netgear router and all devices except the galaxy s4 can connect fine without any issues. It started happening after my phone automatically updated to version: I9500UBUAMDK, but I am not sure if it has to do with software.
If anyone else is having the same problem or has a solution, please help me through this issue, thanks.

Anyone? It's the only problem I am currently facing with the phone and is a major problem for me as i use Wifi at home all the time. Please help me solve the issue and I'll be so happy!

i have also problem with my dlink 2640b and i found solution for me
you need to go to wierless settings and chosse CHANAL 13
and in option where you can chose wifi speed ( like b only, b and g mixed, only g ) chose G only
after that i don't have any problem with my s4
i also have security off

Thank you for the reply, and yes I have read that this problem is mostly on D-Link routers and that there are many fixes for that, however I am currently using a Netgear router which I haven't heard many people having problems on, so there are not so many fixes out there for that. Thank you for the reply though, I will continue to look for a solution.

Try changing the channel width to 20Mhz. After I did that the reconnecting issue was gone on my D-link router, but as you've read at 54g speeds. I can now stream video to my TV without it stopping. I am contemplating buying a new 802.11ac router to connect at 433Mbps as my D-link is too slow for my broadband now. I hope that helps.

Changing Wifi channel width from 40 MHz to 20 MHz solved wifi dropping and reconnecting problem for me also. I have Asus RT-N16 with latest updates. Also on my SGS4 has latest updates, stock android 4.4.2.
I used Wifi scanner, and there should not be any interference with my Wifi station. I have channel 1 and my neightbour has channel 7 Wifi. Wifi signal is also strong for my router. I was wondering how this can be possible, as any other device had not dropped connections @40 MHz widht, BUT a brand new Galaxy S4 GT-I9506 drops it withing minutes again and again?

[Q] help wifi won't connect after upgrading to 4.3

Hello,
I'm hoping someone can suggest a fix, yesterday I upgraded to 4.3 using adb. I'm fully stock not rooted. today for some reason it won't connect to my home network. It's a cisco e2500 router and its on the 5ghz band. I tried setting different channels, turned off optimization....
what gives???

Seems like there is an issue with your router. Did you change anything recently in the router setting? Try restarting the router.

I had immediate problems with Wi-Fi after updating as well, I don't know what the new radio features but it turned out that a firmware update to my router had everything running smooth as butter again, actually better (a lot more reliable–YouTube app actually appears to buffer noticeably less and not break up, for example, downloads also initiate and complete more solidly) than it was under 4.2.2

I have the same problem, since the update to 4.3 does not connect to the 5Ghz band.
I'm back to 4.2.2 and not connect, does it damage my hardware nexus 4?

I'm using an Asus AC66U at home and N66U at my office with no 5ghz connectivity issues.
Here's some things that might help you troubleshoot. Start by disabling the "avoid poor connections" feature in WiFi options. Install inssider or similar WiFi scanner to see if there is interference for your specific router config. Try removing the WiFi connection from your phone and reconfiguring.

Hi,
It's strange I have a similar problem. After upgrading to 4.3 my 5ghz connection came to a crawl. We are talking about 1.2-1.6 Mbps. But the 2.4 ghz was fine (35 Mpbs). Once I downgraded, re-writing the "radio" file, then the 5ghz connect was blazing fast again (50 Mbps). I'm convinced this has to do with the "radio" update, but I'm not sure what exactly.
Any suggestions? Currently I'm back on 4.2.2 as wifi speeds (PA rom) make more sense right now.
Thanks in advance!

I tried all of the above, every combination, reset my router, there are no other 5ghz overlapping networks, at this point it is something to do with my install. I wonder if a factory wipe would help...

That's my exact setup (E2500' did you set the Wi-Fi frequency band to 5GHz only on the N4 and give the band a different SSID from the 2.4 GHz network?)! Try forgetting the current connection and setting it up again.

I'm pretty sure it's not your router setup and the radio upgrade, as I mentioned earlier. Try going back to stock 4.2.2 and see if you can connect

If it were the radio software specifically, then logically 5ghz would be broken for everybody, which is not the case. Perhaps the issue is device data specific... There has to be a better solution than staying on 4.2.2.

I have with wifi problems too, but with 4.3 and 4.2.2 version. At home everything works fine, but at work phone connect to router, but no Internet (internet work only 1-2s). Other devises with this router works fine!

I have even a different issue. The phone is stuck at Obtaining IP Adress every time now. I downgraded to 4.2.2 and it's still doing the same thing. It does work if connected to a different router, but not to my main one. I haven't changed any router settings either.
