wifi issues...not typical - Galaxy Tab General

im having an issue connecting and detecting my schools SSID. they use meru access points. i have tried it in several buildings and heres what happens.
if im lucky the SSID will come up in the wifi settings
i tap on it
attempts to connect
never gets to the "obtaining ip..." part
right under where it says Wi-Fi it says disconnected
the SSID disappears
we use WPA2 authentication.
-tried hard reset
-tried switching out the wpa_supplicant file with one that supposedly works
nothing. its really frustrating. it worked before, in the past, like a couple months ago but now it just doesnt. i called IT, which i never do, and they were useless of course. they did say that the ethernet chipset could have an issue with keeping a live connection regardless if the SSID is broadcasting but offered no suggestions.
what u guys think?

Not sure why cannot get connected to wifi since day 1

Hi Friends,
Hope you could help. I have a X1 and I been trying to get it connected to my DIR-655 thru wifi with no avail. Surprisingly, I have 2 wifi network at home and it could get connected to the other one. I am sure it is not a router issue as my iPhone could connect to it using same login settings. Both my wifi routers are on WPA2. This is really puzzling me.
Cheers and thanks,
I have trouble with WPA2 security as well. WEP works just fine, though.

But the thing is it is working with WPA2 with my other router. Very strange.
I have the same issue. Can't connect to my wi-fi router at home, though have no trouble to access others. Or better to say I get connected, but internet is working either too slow and too short, or not working at all.
I did have this issue when I gott my X1,
after a few days I unplugged the router for 2 mins and plugged back in, then waited until it started up and tried to connnect and it worked.
dont know why it worked it just did so maybe it will help you?
Have you tried logging on to your router, and allowing your X1's IP address.
Thats what i had to do on my netgear.
well, I've even arranged a static ip for the mac-adress of my x1, enabled DMZ for that ip, but still doesn't help.
I've pulled the plug of the router out many times so far, doesn't seem to help.
routers are basically rather small computers
their firmware have bugs
which is why the manufactures
put out firmware updates to fix those
newer wifi devices like phone of often give issues
with older routers with older firmware
updating firmware is pretty easy and can be downloaded from the manufactures site
yesterday I tried again and I don't why, but it is working now still a bit slow and some programs don't connect (QIP, SPb Online tv etc), but at least browsing works.
p.s. forgot about router firmware, gonna try it tomorrow.

[Q] Reboot router to connect to Wifi

I'm puzzled by the behavior of my phone. For probably a week at a time, I go to work, connect to a WIFI there, then come home, connect to a WIFI there. No problems at all.
Then it seems like after a week or so of 'being good' sometimes I'll wake up the phone and it will see the network, but will not connect to it, asks for passphrase repeatedly (WPA2-AES Cisco E3000 router) but just will not connect. I have found no way to trigger the phone to reconnect (and I refuse to do another hard reset because that is no solution at all).
The simple fix is to reboot the router. Presto, the phone will connect almost immediately.
I am willing to accept that maybe something is wrong with my router, although I have 3 laptops and a couple of IP cameras, and an Xbox that connect wirelessly all the time, and I never ever see this refusal to connect on any of those devices, and my wife's Blackberry will also connect whenever. So I'm thinking its my phone.
So for the experts out there, what is it about rebooting the router that fixes the problem?
I only recently learned how to get into the manufacturer's special app, so I'm going to pay attention to my IP address next time I have an issue, and see if it actually changes when I reboot after this problem occurs again.
Where does one discover how and what can be tweaked in the secret app? I'm cautious but not afraid....hey, I've edited the windows registry countless times on my PC and never toasted the OS yet! Does that count for something?
Add: I had this happen once at my work WIFI, using an ancient DLink router using WEP. At the time, I was trying out a bluetooth headset (Plantronics Backbeat), which worked, albeit, after I was done listening to the podcast, be darned if I didn't get into this refusal to connect thing, and unbeknownst to me, I was using the 3G data connection for what I thought was a wifi broadcast. That sucked 175 megs that day! I was a bit pissed about that. I have not used the Bluetooth since then.
Rebooting my router at work fixed the problem but I hate doing that, because I've got other equipment on that network that likes to be permanently connected.
the same happened to a frined of mine: interoperability issues with that model of router and the phone, changed the router and after everything worked perfectly, that sucks, but it is
Had a similar problem, and simply could not pinpoint the cause. Solution? I resetted my router to factory settings, and started to change all the settings from scratch to my desired settings. One thing that helped solve my problem was that I changed the default IP address used by the router (in my case, 192.168.0.1) as well as the IP range to something more ... random. Also, I limited the number of allowed IPs to 10 rather than the default 100...That helped. Never got a disconnect or problem connecting again. I had the same thing happen on my mother's iPhone and my brother's Galaxy S, and this solved it.

can't connect to my home wifi

i got my new omnia 7 today and i can't connect to my home wifi router. i tried to disable security, tried wep.....but it allways says "couldn't reach wifi network" or "password incorect". i tried to reset my router and my omnia 7, but nothing helped.
thanks in advance!
today, i connected just fine on one open ap, and one wep protected ap, but i still can't connect to my home wi fi ap. really confusing. my laptop and old htc prophet connects just fine, but my new omnia 7 won't. any advice?
thanks!
ok, so since no one tried to help me here, i tried every single thing on my router and it seems that the phone can't handle b+g standards, so i switched to g allone and now i'm able to connect. i hope this will help someone else too.
Nice tip
Hey man,i guess no one had the problem or didnt know what to do,anyway i had a differrent problem,when i was close to my router (no more than 8 meters) my phone connected normaly to the wifi,but once i was in my room which is further away from the router the phone wouldnt connect although it showed the wifi router signal had two bars,i tried your method in switching to g only and it worked ,now i connect to my wifi with no problem,thx for the tip ,hope they fix the issue in mango,cheers.

I have the same problem with my wifi router.
My phone is HTC 7 Throphy.
I have to reset my router every time my phone needs to connect to it.
My router is configured for DHCP.
I noticed that if there is a wireless device connected to my wifi network,
my phone gives that error and cannot connect.
If I try to connect to a wifi network which is secured with a password,
I always get 'Incorrect password' message.
I try reseting my phone with no effect.
I'm still looking for a solution.
Same prob here....

no problem man.
it seems that there are many troubles with wifi on windows phone 7 and many users are complaining. i hope too that mango will fix most of those issues. mango will bring possibility to connect to hidden network.
for other users posting on this topic, i suggest that they try switching to g standard only, becose i too had this incorect password message allways poping up before the switching. it can be done in the router web configuration interface. u get in usualiy by typing 192.168.1.1 in your adress bar.

My router is on g standart only but I still get that error.
well, if you know what you'r doing, you could try different configurations in your router. play with the settings and see if it will work, but again, only if you'r sure you won't screw up anything.
I found a fix.
In my router settings I changed the Chanel from 6 to 10.
I think the problem is that I have too many wireless devices in a small room.
you lucky bastards with wifi connectivity.. i have a pppoe account on my wifi and there is no way for me to connect to it whatsoever.
if you have access to your router settings, you can change briged to routed connection.
for some reason, i can't access router! i tried contacting my ISP, did not want to die waiting for an answer.
but i remember trying to do that before, and not knowing how.
Could you post a link with the instructions, zemljak?
you have a pm.

i dont know if you are receiving my pm's, i dont see it them in sent.
I have this intermittent connection on a netgear wireless router too, its set to use dhcp, and only fix is a reboot of the router.
I think the phone is storing an ip (dhcp assigned) which when you reconnect to your wifi may have been re-assigned (ip lease) to a.n.other device in the meantime.
So, lets say on Monday I obtained 192.168.0.2
didnt access the wifi for a day or so
lease expires (router)
a.n.other device connects, e.g. iPad, obtained 192.168.0.2 via dhcp
then you try and use your wifi on your phone and it doesnt connect.....
so I think it might be storing the ip address, rather than checking for a new one each time it connects, or something similar.
Over a half year I had the same problem. But now I fixed it, by simply change the wlan-key, because in my old key I had letters like ä, ö, ü. That didn´t work. May be this works for you.
FIX!

Hi,
I have Nokia Lumia 800 with Windows Phone 7.5 and also have problems with my home wifi connection. Firstly I had an old pentagram router and couldn't to connect with it, I tried WPA, WPA 2, WEP, WPA 2 mixed or even no security, always had the same problem, shows "network don't respond".
The phone itself connects to other networks, but not my home network.
I thought that it was problem with my router (but every other device had no problems with conenction, ipad, galaxy s, laptops or even TV), so I took another router (techniklab) and I have the same problem.
On both routers in "active clients" I saw the phone when it was trying to connect, logs looks like:
Code:
Aug 20 22:13:31 wlan0: WPA2-AES PSK authentication in progress...
Aug 20 22:13:31 wlan0: A wireless client is associated - 50:2D:1D:E2:8A:87
Aug 20 22:13:31 wlan0: Open and authenticated
Aug 20 22:13:53 wlan0: A wireless client is disassociated - 50:2D:1D:E2:8A:87
Windows on my phone is up to date, router firmware also.
I can add that from couple of days I have Windows 8 (on PC) and it also cannot connect to my router, could it be some problems in new microsoft windows??
Any suggestions?

Major WiFi connection issue

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!
OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??
Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?
Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.
This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

Nexus 4 WiFi Problem

I rooted and flashed my phone last night and everything was fine other than 1 thing. The Wi-Fi wouldn't connect on my home router. I tried several different roms and was left with the same problem where it was stuck on either obtaining ip address or authenticating. I then came into work this morning and the phone connected to my Wi-Fi network straight away.
Does anyone know how I can get around this problem, don't want to be using up all my data at home!
Thanks in advance
Dont get me wrong but did you try to restart the Router?

I second the other suggestion. Those symptoms sound like your router needs a restart if it hangs at getting IP/authenticating.
I'm having the same problem on the network at my university.
I'm having problems with my wifi as well. We have a network here at my office secured with WEP. My galaxy nexus connects to it just fine but my Nexus 4 refuses. It sees the network, show strong signal but it doesn't seem to connect. I did manage to get it to connect once and I downloaded some updates but then the connection dropped and will not reconnect. I've tried various advanced settings (forcing the network to 2.4GHz, changing the power options, etc... No joy. This is particularly frustrating for me as my micro sim has not yet arrived so WiFi is all I have Hopefully it will work at home. At least there I have access to the router so I can make changes if needed. So far not a fan though.
I've got WiFi problems here, too. Roaming between different WiFi networks (home and university) often results in an non functional WiFi connection. Experienced this problem with stock Android 4.2 on Nexus 4 and Galaxy Nexus and latest CM 10.1 nightly on Nexus 4. Even reboot doesn't help every time.
As workaround: If WiFi connection is broken, turn on "flight mode", wait a few seconds and turn it off again. Works for me, maybe it works for your problems too.
I literally just received my nexus 4, and I haven't done anything with the SIM card yet, I just wanted to get things going on WiFi to start. It sees the network I want, let's me type in the password, and lets me click connect. After that it does literally nothing. No thinking, no obtaining IP address, nothing. Any ideas?

I have exactly the same problem. Got the phone today and have tried several different access points - no luck. Restart the phone, no change.
Also, system updates screen said I could only download the update to 4.2 from a wifi connection till the 7th, so i set the date to the 7th and did the update successfully over the cell connection. Still no WiFi. Factory reset - no change.

My university provides both LEAP and PEAP authentication. LEAP doesn't work for me either. But PEAP works. I'm able to connect via PEAP. (Stock 4.2 / 4.2.1 and CM 10.1)
Here is my log. It appears the authentication is timing out.
12-07 10:42:43.863: I/wpa_supplicant(19563): wlan0: Authentication with xx:xx:xx:xx:xx:xx timed out.
12-07 10:42:45.345: I/wpa_supplicant(19563): wlan0: Trying to associate with xx:xx:xx:xx:xx:xx (SSID='XXXXX' freq=2447 MHz)

12-07 10:42:55.346: I/wpa_supplicant(19563): wlan0: Authentication with xx:xx:xx:xx:xx:xx timed out.
All other devices do connect fine and I even restarted the AP to make sure.
This is getting very frustrating. I couldn't connect to wifi at work (WEP, I know...) at all yesterday. I went home, and my WPA2 network at home worked perfectly. I come in this morning and boom, I'm connected just fine to the wifi here at work (the connection was remembered from my tries yesterday). I went to lunch, came back, no wifi. Reboots, reconnections, nothing seems to work. I also have a Galaxy Nexus with 4.2.1 and it connects to the wifi just fine. Grumble grumble....
-Matt
I did a few tests today and it seems to be only when using WPA2 with a pre-shared key. WPA works, as do open AP's.

No solution with stock google image AFAIK, because google does not provide 4.1.2 image for Nexus 4. You can try other custom ROM or ask if some one has successful LEAP wifi story about running custom ROM.
BTW I don't own Nexus 4, I am stilling using Galaxy Nexus, as soon as I upgraded to 4.2 LEAP wifi broke, I flash 4.1.2 back then it works fine.
I found that upgrading the access point (MikroTik) to the latest version allows me to connect.
Seems something in this device does not like some older WPA2 versions?

My N4 has been connecting fine to my home router over the past two days. Suddenly, today, it stopped recognizing the network (shown as "not in range" in wifi settings). No amount of router or phone reboots would get it to connect. I read in another forum about going to Displays in the settings menu, scroll to bottom - Wireless Displays. Turn on and search for wireless displays, then turn off. I thought, wtf? Anyway, I tried this and it connected to wifi immediately. Maybe there's a bug in the wireless display function that's interfering with wifi.
I am actually having a similar issue as others here, but I have found another weird work-around. Basically, although the Nexus 4 see's my campus's network, no packets get transfered back and forth, and I am not even sure what is going on (The IP address, tho, is usually "unknown".) However, upon going to the campus's IT help today, they turned off mobile data, and it then seemed to connect fine over Wifi. Any idea what is going on here?
There is no "signing in" to the network at my university, it just connects and verifies your device's MAC address, so I don't think they are doing any fancy authentication. I was thinking about maybe flashing a different ROM and seeing if I get different results.
i got mine yesterday and it connects then stops connecting after a couple seconds

I get exactly the same issue in my office. I can connect to school open network, but after a few minutes it lost connection (while still showing connected). I got to wifi setting, it shows that there is only one wifi hotspot and i am connected to it. But actually there should be more than five hotspot! If i switch wifi off and back on it can detect all the networks and get connected again, but then it goes to the weird cycle over and over.
Strangely, if i stayed in another office, it is connected all the time. Seems like the signal problem in my office. But i got no problem in my office when i was using galaxy nexus.
I am driven crazy by this!
