Or it's your router or it's your modem.

problem in your router

there is nothing wrong with the router, making tests also with my wifes s4 mini but it never happens.
if i dont use the phone for a while, then do something, the wifi speed is really less.
then i reconnect to wifi, it works good
see the last 2 tests please

It's maybe a combination of your router and the s4. You can easily test this when you are connected on other wifi's.
Or maybe it's solved when changing your modem. It's the one or the other.

Why don't you check your link speed that you wifi is actually connected to you're router? Just cause you got a 150Mbps router doesn't mean the link speed is 150Mbps. Within 6 meters of my crappy telstra (technocolor) router which is 300 Mbps gives me a link speed of only 5 Mbps @ g mode.

No I also told you that it's probably your modem if it's not your router.

1. Reset your router. Unplug it for like 30 seconds then plug it back in.
2. Set best wifi keep options to Keep Connection and Boost Signal
3. Forget your wifi connection on your phone
4. Reconnect your phone to your wifi

Networking problem, need help please

Help,please.
Meet the problem. Transformer connected to my home wifi network. All devices in network connected to the internet, except Transformer. Manually configured network. I tried different wifi networks. All wifi networks successfully connected, but without internet. It looks like transformer could not route. i could not ping machines in the same network. Is there anybody who has same problem??
Thanks in advance
P.S. Who knows how to make routing table? Transformer connects to wifi, can ping himself but could not ping gateway in the same network.
It happend when i started playing with ROMs. Installed different ROMs with super wipe (Revolver, Revolution HD, Megatron, ICS WW_epaduser9_2_1_24, same problem.
have you tried switching the router off for a few minutes and rebooting it?

O yess, many times. If it is router problem, then all other machines could not connect to internet over wifi. Only Transformer could not, and tested on 3 different wifi networks (with and without DHCP)
probably wont help, but what about Kernel - have you tried different Kernels?

I tried different kernels, (Kernel-ICS-V22.6-OC1700-fb-AOKP_646, kernel_asus_rev01) but what kernel would you suggest?
if those have not worked then i doubt any others will. Rev3 Harmony (asus or universal) depending on which base your going to try - or the latest Guevor, version depending on base again.
Wifi is not my thing but thought id ask the obvious just incase. sorry i cant help more but im sure someone will be along soon :good:
WTF.
Installed Kernel Guevor N22.6 and Revolver 4.0.3 ROM. Same problem. Connected to wifi but no internet.
Even I disassemble Transformer and reconnected batteries. Does not help
Is it possible that hardware problem in wifi? Why in that case wifi connected? Magic.
First try turning air plane mode on then off to see if that works also your network may not like androids long default host name so consider changing that if you have root
What router are you using? make sure your using channels 1-11 (not 12 or 13) and check your on 2.4 GHz not 5 GHz
For the present test im using connectify soft and share my internet over my laptop. And it worked before. I installed busybox and did some commands. It looks like oruting table is correct, def gateway is pinging, interface is up. But could not connect to any site over integrated brower, could not connect to youtube or playmarket or gmail. Attached is screenshot. Maybe i lost something.

No one, who can give me any advice??
I reflashed Transformer up to latest ICS WW 9.2.1.27. Did not help. Still connected to wifi, but could not access to internet.
giving your router configuration and brands, could help I think...
in my period of owning a transformer, there are one place at where I live where it can't connect to.. a free wifi at a restaurant.. it just cant't, it detects but it can't connect.. the channel was within 1-11, but still not connectable.. I've tried different roms and kernel, still to no avail.. while my other device can connect to it just fine... maybe there are some router that transformer not compatible with..
Problem is that transformer could connect to wifi network without any problem. It shows that connected to internet, but could not open any site or youtube or gmail.

Is anybody else having wifi issues?

Literally received my N4 about 30 mins ago and Ive set it up etc. Ive noticed that the Wifi seems to be weak compared to all my other devices I have around me (it goes up and down and actually dropped out altogether once).
Anybody else have wifi issues?
hmm...i think so, yes
Gnex speedtest on wifi 5.19Mb
N4 speedtest on wifi 2.11Mb
not an "issue" but definitely slower
I have seen an improvent over my HTC Desire. With my 50 Mbps DL / 5Mbps UL
My results:
With WiFi N: 45 Mbps download / 5 Mbps Upload (The speedtest app just gives random download speed as I don't even get to see the download speed bar) Singal is between 40 and 60% according my router.
With WiFi G: 19 Mbps download / 5 Mbps Upload (Pretty much maxing the G bandwith) signal is 95% as the router is in the same room.
I just got phone this morning. I get my max 25 mg dl 5 upload and have had no issues
Mine was working poorly just as you described. I turned off WiFi optimization in the settings (says it helps with battery life, so I'm assuming this weakens WiFi) and I looked around in my router settings. It was set to 145Mbps (neighbor-friendly mode apparently) and was giving me less than 5Mbps up or down. After bumping it up to 300Mbps (performance mode), it is now giving me full speed for my 30/5 connection.
I'm having trouble connecting to my cisco router. It would say either "obtaining IP address" or "authenticating", then the connection breaks and it attempts to reconnect.
No issues for me.

Change the configuration of your router. Set an open connection and try again.

I had an issue on mine where it lost connection with my wifi router, then kept showing no networks in range (usually there are around a dozen showing up due to neighbors). I tried turning wifi on and off, going into airplane mode, finally had to restart the device entirely to get wifi to detect any networks again. Hasn't recurred, but it does make me concerned.
Seems good to me:

I'm having problems connecting to my Buffalo router with WPA2 security. It connects just fine to my guest network that uses WEP authentication on the same router, but it just says authenticating or obtaining IP on my main network. My router is a BUFFALO AirStation HighPower N450 - WZR-HP-G450H using DD-WRT... Is Buffalo crap and that's my problem?? My Gnex connects to it fine.
I've tried disabling/enabling wifi, airplane mode then out of it, and rebooting my Nexus 4 without any luck.

Have you used the same SSID on your 5GHz as on your 2.4GHz?
If so: they must be different!

My Note 3 Work very well on 5 Ghz, is my wifi at home. Router Belkin.
Look whit Wifi Analyzer, option wifi channels. You see all of the 2,4 Ghz, and if You touch on top left it change to 5 Ghz. You must see Yours.
My N9005 connects to my Asus RT-AC66U, but keeps complaining about an unstable internet connection. My old SIII worked fine. Compatibility issue between N9005 and Asus AP's?

Did you find a solution? I have the same pproblem.This plus the unstable connection problem is making me miss my note 1
Found this link http://forum.xda-developers.com/showthread.php?t=1675547 on 5ghz connection issues on Note 1 in Hong Kong. It describes channel limitation based on region. The file in my etc folder has ccode=GB which I assume is Great Britain. However, it allows the channels that my wifi router EA4500 is using on the 5ghz channel. So no luck on recognizing the 5 ghz network still.
I downloaed wifi analyzer and looked at my network. By default my router and I assume all the ones in my neighborhood use channel 1 on 2.4ghz. I just switched to channel 12 and there hasn't been any issue for the past hour i.e. no unstable connection warning from the phone. Just downloaded a 40MB file without any glitches at good speed. Will report back if the problem comes back.
Edit: Spoke too soon. Unstable connection warning back in a couple of hours. The interesting thing is that both my old Note 1 (N7000) and my wife's S4 can see and connect to the 5ghz SSID just fine and of course have no unstable connection notifications which seem to be an 'enhancement' in the note 3! Sigh Haven't even rooted the N9005 because of the knox flag or I would have played a bit with the wlan configs in the etc folder. Guess will have to wait for Samsung to come around to admitting a problem and then fixing it.
I've been having the same issue with my RT-AC66U.

I also have a RT-AC66U... and I'm connected fine with my Note 3.
go into your wifi settings and make sure that the third checkbox is not checked.
Name in french of this box is "Basculement réseau auto"...
With this setting enabled, my wifi is unstable even if the signal power is full.
Also make sure that you have the latest firmware on your router.
Try channel 48. Dont use those channels 160+, may not be supported.
I'm using an AC66U.

I've only get 1MB per secound at download and also 1mb per secound on upload, my network is 50000 Kbits download and 10000 Kbits Upload speed.
I had SGS4 and on Android 4.2.2 I realy got 4,5MB per secound at download and 1MB per secound at upload. All was fine, I was happy :fingers-crossed: I updated to 4.3 and got same s*** as now on the Note 3.
Anyone know how to fix this issue? I have FritzBox Fon 7390 and Wifi Range Extender from Sitecom.
All other Tablets and Laptops got full speed at 2,4Ghz Wireless.

I have disabled the 5Ghz band, because my Note loses the conection using it. Thats the reason why I use only 2,4Ghz.
Can't I get more download speed on 2,4Ghz?
You have very fast network dude
What router are you using?

The 2.4GHz-band is very busy with more users on WiFi; the 5GHz-band is NOT used very often by users, hence the speed!

Droid Turbo 2 WiFi problems

Is anyone having an issue where WiFi disconnects on its own and seems to disconnect the phone from Verizon's network as well.

I haven't had that problem. I only had a problem with the advanced calling feature turned on during a call.
I did where the phone showed still connected but router showed disconnected. It is not a phone issue, it was an issue with my Linksys N router

What was the issue with the router causing this? Did you fix it?
Thanks!
It seems to be a problem on both the Turbo and the Moto x pure, many people in the Motorola forums say they purchased a new router and it seemed to work. I personally won't be buying a new router just for this phone. Hopefully it will be fixed with the marshmallow update
Well I disconnected my Linksys Router and used the Comcast modem and setup WiFi with it and works great now
extremely frustrated with turbo 2 wifi
I'm having the same problem, and it's true on at least 3 different routers so far. I surely won't be replacing every router I ever need to connect to. As a frequent international traveler this is a HUGE problem for me and will result in my getting a different phone before my next international trip if it is not resolved quickly.
Are they all linksys

No. Haven't tested on any Linksys. All were Netgear routers, 2 with N (running DDWRT) and one with AC (factory firmware) protocol.
Don't know then. Mine has worked fine on a netgear R7000 on stock and dd-wrt.

Question: Are others who are having this problem on open networks because I share am open network with other people who live at my residence and I don't have this problem when I am visiting my friend who has a secured WiFi connection.
