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.

:crying:
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.

hello,
i just got a new note 3 and i am loving it but i cannot connect it to my 5GHz wifi. its cant find it at all.

hope that helps a bit

thanks jaythenut,
"keep wifi on during sleep" set to always by default and i don't see anything else.

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.

Thanks, I had same problem with my Note 3 not finding 5ghz and switching the 5ghz channel to 48 did the trick.

why is wifi speed getting slower?

everytime i try to download something or use internet on my phone, the wifi is toooo slow.. but when i turn off the wifi and turn back on,
then i get higher speed. but after a while it will decrease again :/
i have 150mpbs internet
i9505 S4 omega v28 4.4.2 (before this had 4.3 pyrana was also same)
any ideas?
here is the test image, i just did the last 3 tests

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

Slow WiFi Speeds on Z5 compared to other devices

Over the past day or two I've noticed the download speeds on my Z5 to be slower than my other devices on WIFI. I'm not sure if it's cause and effect or just a coincidence but my phone fell 2ft/70cm when it slid off a table and fell onto timber flooring landing directly on it's back.
The phone has a case but I've done a factory reset and the problem still persists. Perhaps I've damaged the antennas but my mobile data appears to have had no change in speeds. The speeds varied on my phone over these 2 days ranging from 1-3mbps compared to the normal 6mbps i get.

Check your modem/router frequency that it use to send out the WiFi signal, and if you can change the frequency of your modem or router then change it to something else and do a Speedtest.
With a app called Wifi analyser you can see which frequency band is best to use when you connected to your Wifi.
If none of the above steps helps, then I have no idea what it could be, my Wifi works great anyway, getting 11 mb/s download speed from my modem.

Z5 connects to AC router with 866Mbit/s speed.
Speedtest reaches 100Mbit/s with ease on Z5.
Check your router.

Yep same as you, in addition if other devices are connected to the same band at slower speed they will also kill the speed of any other devices on that band

No the case won't affect this, in addition what are you actually talking about, your speed has gone to crap accessing files within your network, or are you talking about the internet. Because there are so many variables that can affect internet speeds, and a huge percentage of them are fully beyond your control.

I ran some speed tests at a friend's house to see what was going on and it seemed to show similar speeds against my friend's devices also connected on WIFI. I'm suspecting it to be a problem with my router but will run a few more tests with a borrowed router.

I am having problem with wifi, it says connected, but no internet access.
This is happening lately, mostly after last update .182
I don´t know but since then I have restarted my router for three times now, on laptop I don´t have any issues.

Speedtest gives me 219/200mbit/s on my z5 compact, could be better but it's acceptable for a phone

Other than home (which does not have any issue) I do not connect to other wifi. But on my recent travel, i've had the same issue as you connecting to various places which has wifi. I believe its due to router settings mostly.

I'm getting the opposite - mine's a disconnection issue. No WiFi connection issues but when I leave the house my E6653 sometimes fails to drop the WiFi connection for mobile data so I'm miles away with "Connected, No Internet" with a bang (!) next to the WiFi icon for my home SSID - far out of range! Turning WiFi off and on again sorts this out, i.e. mobile data connects instead.
Anyone else?

It seems fine for me but bluetooth and wifi on at the same time causes some imense lag.

My Z5 has BT on 24/7 (paired with smartwarch 3) and no WiFi lag.
Change channel on WiFi.
Channel 1 can mess up BT and vice versa.

I had to disable 5Ghz band on my router to connect a few ipcams. They do work now. But am I destined to have 5ghz band disabled if I want the ipcams to work?

Don't use same name on the the 2 networks, and make the ipcams connect to the 2.4GHz band.
Eg: 2.4GHz is named [email protected] and 5GHz is named [email protected]_5GHz, also disable band steering (if your router/ap supports it) if the cameras are supposed to be 5GHz "compatible" but actually don't work on it.
