[Q] How to fix wifi issue?

I have had lot of issues with wifi connectivity on my Infuse. The connection to the wifi networks takes a long time and it keeps scanning. After it connects, if the phone is idle for 2 minutes, the connectivity goes off. The signal on the screen shows that wifi is connected but the webpage never loads. I need to toggle wifi to get it working.
I have tried a lot of things to get this issue fixed. I have set the wifi sleep policy to never. I tried using static IP. I installed a few apps from market that try to reconnect when wifi goes off. But none of these worked. I read that you can manually enter the MAC address of your device on ur router to get this issue resolved. But sadly, I stay at a university dorm and I have no control over the router settings. I can't play around with it. I also read that the problem may be due to hidden SSID and tried an app to get a work around but in vain. I'm totally clueless since this issue is seen only in my university wifi network but nowhere else.
It'd be very helpful if the seniors here could guide me into getting my beautiful Infuse connect seamlessly with my wifi network. I love my phone but I'm really sad that it has wifi issues which drive me crazy sometimes...
Thanks in advance.
PS - I had posted the same query in LinuxBozo's Hellraiser FAQ thread but I reposted here since I think more people would read it. I hope the admins don't mind.

Are you on a custom Tom?

did you download that app
typically when you go into a rom with issues...ie you were having the issue stock..it isn't the rom
I have a feeling it is a weak signal from the university's wifi and combined with weak reception from the infuse
out of all of my devices the infuse has the weakest reception

Which app are you talking about?
It's not the weak signal from the university. The routers are installed inside our rooms and the signal strength is either good/excellent. If I come to the hall, the signal strength goes down but at least inside the rooms it's good. But even then, I have this issue. It connects initially but suddenly it disconnects and I cant open a page. But the signal shows it's still connected. It's kinda weird. And I'm surprised no one else has faced this issue. 2 of us have the same phone here and both of us have the same issue.

it is either the network or it is your phones

Sounds like a network issue to me, or possibly a side effect of the Android DHCP lease issue.

More likely to occur with a large multi-access-point university network.
I don't know if Google has fixed the above issue yet.

Home WiFi Issue

My phone keeps dropping wifi and then reconnecting on my home WiFi network... I have heard there has been issues and that the network has to be configured the proper way... Does anyone know the exact settings that it should be configured? Thanks for the help!!!

I don't know of a specific configuration which solves all issues and Verizon told me that Samsung was planning a "second" update in October timeframe the addressed WiFi connection issues when I called in July about this.
That said, my WiFi connections have been far more solid since then for no apparent reason, so perhaps there was temporary interference at the time - I did adjust my router to use the (2.4GHz b/g/n) frequency up to 130Mbps for the channel (6) used by my Galaxy S III, instead of the (5GHz a/n) frequency that is configured for up to 300Mbps, but am not sure if that made a difference.

Thanks! Its weird because my wifi at work connects just fine but at home it goes in and out every 30 seconds to a minute...It must be the router configuration...im gonna try and mess with the settings when i get home

It's a problem with your home router or main modem. Verify that the ip on your router and modem match, if not sync them. That's the most common problem. Also, reset your main modem, have your provider ping and update it. This happens to me time to time, mainly with netgear products.
As mentioned above, use the 2x not the 5x band if you have a dual band router.
Also, some cable Internet connections can get fuzzy if they are using old co-ax wires in your house.

You know I was having the same issue. After owning the s3 for 5 days now, after the 3rd day I started to experience wifi issues. I would be connected to my wifi but no Internet connection af all. So I messed with the channels on my Netgear dual band router. I switched channels from 1 back to 6. Still nothing. Finally I reset my main modem(att) and also reset my router back to factory settings and still nothing. My wifi has been working fine with no hicups until I got the s3 and my wife has the rezound with no problems what so ever. Until yesterday, what I did notice was my whole Internet connection went down. Now I don't know if it's att or me. Well, it's back up right now but what I did do was call Verizon and they had me take out the sim card and reboot the phone while they did some things on there end. After they came back from hold I rebooted my phone and since then I have had not 1 wifi drop at all. They told me if I have anymore problems, that I go to the nearest Verizon store and get a new sim card. But I really don't know how that would help out at all since the wifi is built into the phone. Those techs are funny. But ever since that rebooted and removing the sim and also having Verizon do some things on there end. It's been perfect and no drops at all.
Ohh and also I did do the *#0011# wifi sleep mode trick to off. Didn't work for me also. But what was weird when I did that trick my phones screen wouldn't go to sleep. It would stay on until I hit the power button to make it go to sleep.

Internet connection dropping out on wifi

I just received my Nexus 5 today. Got it all set up and I have noticed that the internet connection kind of drops off when I'm on Wifi. I have full bars, but there will be no data. Josh reported similar behavior in his review model on The Verge.
I can't tell if it's a wifi specific issue or not yet. I turned off the "save battery" option under wifi and it's still doing it. The phone will simply stop receiving data in any app. It's not my router. My other devices work fine. I am rooted and do have Adaway installed, but this doesn't affect my Moto X or Galaxy Note 3.
Is anyone else experiencing this issue?

I've been trying to look at current wireless issues and this one is a little new.
So far (No tethering on Sprint - problems with some T-Mo) and that it doesn't see 2.4Ghz channels past 11 and that it can't see some 5ghz channels either.

I can confirm I have this issue as well, I have got my N5 now for 2 days and the problem started yesterday. I have 2 broadband connection at home and cannot receive data on either router, It was working fine until yesterday when the problem started. I have restarted the device several times to no avail. Am not sure why this is happening , do I have to send this back anyone?

I would play around with the router settings if anything.
See if your router is doing 2.4 ghz or 5 ghz.
DO all possibilities before resorting to the exchange.

Oh god, the Nexus 4 had this problem also. Was something with the Qualcomm-drivers. My Nexus 5 picks up notifications much faster, but sometimes I notice a delay for a few minutes (2/3 minutes), with an app like WhatsApp - if it hasn't been in use for a while. With the Nexus 4, I sometimes received my notifications like 30-45 minutes later.

My router is currently set to auto between 2.4 and 5ghz. Also I have had issues with phone being stuck on edge or sometimes just stuck on gprs and it happens mostly just when I need Internet access. Google is disappointing.

And am at work now and the wifi that was working okay yesterday has now stopped working ... I think this has to go back, such a shame.

I can confirm I have the same Wi-Fi dropping issues on my Nexus 5.

Yes, quite a few threads here describing this same problem. Hopefully a mod will join them soon. I too experience this issue. Someone noted Nexus 10 had that problem at launch which Google fixed shortly after with a software update. I noticed Google support forums also have this reported. Fingers crossed for a quick fix from Google!

Wifi bug - connects to network, but not internet

I'm experiencing a bug on my Nexus 5, when I first unboxed my device and setup this problem arise for the first time, problem is Nex 5 is connected to my home wifi network but no internet connection/data transmission !! at that time I tinkered a little bit like forget network and reconnected it then it was fixed, after that this problem rarely appear. Then comes the real problem yesterday I rooted my phone then it wont connect to internet same as before connection is accepted and have full strength signal but not connecting to internet, I've tried rebooting, forgetting and connecting, troubleshooted PC etc but nothing seems to fix the problem !! I double checked my network like I connected my tab with wifi and it's working perfectly fine.
Is this a common/known bug with Nexus 5 ? Or it's just me ? (h/w issue)
Any known fix other than I mentioned ?
Does rooting caused this problem appear more frequently ?
Any response will be highly appreciated.
Thank you

Try connecting to a different network, it may be a compatibility issue. Also try rebooting your router/wireless. If that doesn't work then try restoring factory image.
If none of those options fix it then there could be a problem with your Nexus 5's hardware

I'm now flashing factory images, if that doesn't work I'll do a replacement.

I have this issue too, with different WiFi routers.
(Full stock Nexus 5)

Out of intetrest what countries are you connecting in. When I had a Desire HD I had trouble connecting to Turkish routers. Different frequencies? Have you ever connected to your router with an actual connection?

Have yu tried disabling wifi optimzation?

I did tried with each and every option toggled with but still no way.
Sometimes out of nothing it gets ok then goes bad again.
I'm from India and using Teracom router. Funny thing is my tab here working just fine with my home wifi network, I'll try with another wifi network tomorrow.

Merely rooting the device would have no effect on the Wifi connection. Did you also install a custom rom or kernel?

Yeah, so it's a wifi thing. Did you try changing the channel on the router? You can use inSSider to find the best one.

WiFi 5 Ghz issues

I've noticed whenever I connect to a 5Ghz network, it's complete garbage. At my house, when I connect to 2.4 Ghz I get a consistent speed of around 75mbps, when I switch to 5 Ghz, I can't get more than 20 consistent. Sometimes it works super quick for a second, and then anything I try to do, web surfing, videos, downloading apps etc.... just suddenly stop as if I have no connection and never start again.

No issues here with 5ghz - can only suggest resetting router and phone, otherwise perhaps you have a faulty handset.

Also no problems here. I find the range off the antennas great.
Did several speedtests and no drop outs.

Just got mine and AC 5ghz works great. Getting 235/23 mbs on my home internet.

I have the same issue. Inconsistent connection and slow speeds on 5ghz, only way to fix is a router restart, but then if i turn off WiFi and re-enable, the problem returns. Possible IP issue?

When I received the phone 2.4ghz was fine (110/110) but 5ghz was not (550/3).
I had to go to setting > WiFi > Advanced (in the "..." menu near the gear on the upper right corner) and uncheck Wi-Fi optimization.
Then I got 550/250mbps
Not sure if it's relevant to your problem, but you could try that.

Good point. Seem to remember something similar on the 10 too. Thanks!

You're welcome Hope it will solve your issue.

Unfortunately, that didn't work. Got a replacement handset yesterday, just to be sure that it wasn't the phone, same problem happens?!
I use a Linksys router, if the op is still on the thread, what about you? Have no issues on other 5ghz networks. Well, the other 2 that I've connected to.

I think I remember a bug with some Android phones on 5Ghz if IPv6 broadcasting was enabled in the router. Are you using this? Tried disabling it?

Thanks, i'll give that a try. I've never had this issue with any other phone, it's very odd and actually frustrating. While I can fix it at home, I wont be able to modify router settings when out and about, so if I struggle to get WiFi on the move, i'll be paying a fortune for data, which may force me to return the phone.

Just tested mine with Virgin Media router and WiFi optimisation turned on. Maxed out at 220Mbps

I'm noticing issues on a Linksys router as well. My wife's old M8 had an issue that would go away when Bluetooth was turned off.
I messed with settings tonight and it seems more stable. I just made 2.4 and 5 on SSID, and changed all band settings to Auto.

If its happening on other connected devices on your wireless network either 2.4 or 5Ghz try changing Router channels.
I've seen this happen on 2.4Ghz. Turns out since I lived in a pretty Wifi congested area the channel my router kept picking as "The best" was actually 6 and all the routers default to that channel. Literally that frequency was so bugged down my internet went from hitting 60-80Mbps down to Kbps. Wifi Analyzer showed all 12 channels were pretty full. I switched to 5Ghz only and immediately saw a difference, but the few channels I do have on my router are getting congested nowadays too.
Nowadays whenever my phones Wifi speeds hit the floor I do speedtest on other wifi devices and Ethernet speeds. If theres a significant difference I quickly use Wifi Analyzer to see if its time to switch channels.

when i got my htc u11 unlocked i had problems with the wifi not connecting at all or if it did it would disconnect. i found that there was a software update so i downloaded it on my mobile data. once installed everything started working correctly. mine will connect at 866mhz to my dlink-879 ACN router

The ivp6 thing or whatever is what I did when I got the m9, it wouldn't connect to my wifi at first and it was 5ghz

I forgot about that option. Had issues with my 10 when it came out a d that fixed it, so far it's working on my 11.

Still having issues with this. Tried above suggestions, not specified a channel, currently set to auto. My M9 and 10 have no issues holding a fast connection. Getting a bored of it now, as trying to stream Le Mans and it constantly cuts signal.
