Ideapad U410 - No WLAN Connection At School

Hello Lenovo Community!
I'm currently dealing with an issue with wireless connectivity at my school.
Background:
I have a Lenovo U410 with an Intel(R) Core(TM) i5-3317U CPU @ 1.70GHz, 1701 Mhz, 2 Core(s), 4 Logical Processor(s). I'm currently running Windows 8. My computer also has an Intel Centrino N2200 wireless card. WIth this wireless card, I"m able to connect to most wireless networks. I can connect to my home network which is a 802.11g network with WEP security. I bought this computer in late April 2013 at Newegg.
Our school has two wireless networks. Both networks are 802.11n. One with WPA-2 Enterprise encryption and the other that is open (insecure). When I try to connect to the encrypted network at school, I type in my username and password, but it refuses to connect. There is no connection to the school's wireless network at all. When I connect to the second unencrypted network, I'm able to connect with no internet access but with network access. Note that Ethernet still works. When I disconnect from either network to try and connect to the other one, both networks disappear and I'm forced to disable/renable the adapter.
Note: I was able to find a driver that allowed me to connect to the networks with no problems. I have yet to relocate that driver.
Note: I'm not able to go to school to try and test out any solutions, but please try and provide as many as you can! Thanks! I"m thoroughly stumped.
Things I've Tried:
I have tried to find every single driver on the planet that could help me with this wireless issue. Like I said... I found a driver that worked. The only fuzzy memory that I have of that driver is that it came from Lenovo in ShenZhen.
When I install drivers, I always uninstall the previous driver via device manager before installing. I always delete the previous directories where old driver setup files may still be. With every single driver I try, I get the exact same result.
I've tried drivers from Lenovo for the U410, the U310, the U410 Touchscreen, etc. None have worked so far. I've also tried backdating drivers to Windows 7 and Windows XP. None have worked here either. I've tried drivers from Intel for the Centrino N2200 Wireless Card with no success.
If somebody has any solutions or has found a driver that I'm talking about, please post it!!
Here are some drivers that I already tried:
0ttp16ww.exe
0wwi02w8.exe
0wwl13w8.exe
Wireless_15.8.0_De64.exe
WIreless_15.8.0_e64.exe
h1wf05ww.exe
If you require any more information, please feel free to ask. I can't go to the school to try and access the network. Any diagnostic information will have to be from what I already have.
Thanks!!

Hi Brettd,
> now no connection at all. Connects to modem with "limited activity"
Thats confusing. At the moment do you have no connection or limited? Both is not possible ;)
I would recommend a WLAN driver update and you can download newest WLAN driver here:

Also make sure that MAC address is not blocked in router and update the firmware of your router.

Ideapad U410: Improve Wifi range?

Hi,
with my new Ideapad U410 I recognize large differences comparing to my thinkpad edge concerning the range of wifi.
Is it possible to improve this?
maybe with an other wifi nic?
greetings

Hi FastDun, welcome to the forums,
sorry you haven't received a reply as quickly as you would have liked, but this is a peer to peer forum it can take some time for the right person to come along with the right answer; forums in general usually require a little patience.
That said, it sounds to me as though you have a possible problem with a firewall software. There are a few posts in the last week where it seems McAfee has been the cause of the problem, happened also to a friend of mine.
Can you connect using safe mode with networking? If so and you can't connect under normal Windows operation this would confirm a software firewall is the culprit in which case I would suggest uninstalling and then reinstalling the software after a new start.

Ideapad u410 display and suspend problem

Hello,
My Problem is, that when I close the lid of my ideapad u410 it suspends, but when I open it again it sometimes works as expected, but most of the times the screen is displaced. (Everything is moved about 500 pixels to the right and a bit upwards too.)
For now I have set my laptop to completely shutdown when I close the lid, which works fine, but I would really prefer to get proper suspend working.
I also experienced this displacement once or twice when booting the laptop normally.
this is the output of xrandr
Screen 0: minimum 1368 x 768, current 1368 x 768, maximum 1368 x 768
It's weird because the actual resolution of my screen is 1366x768, and I noticed that when I move my mouse to the left or right border of the display, the screen actually moves these 2 pixels to the left or the right.
This might be a whole other problem, but they could be connected too, I guess.
Info of lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce 610M] (rev a1)
I am currently using the nouveau driver.
Another problem I noticed, that might or might not be connected to the first two, is that I can't change my tty.
When I press ctrl+alt+Fx the screen just goes blank and I can't even change back to my previous session.
(Usually to get the function keys on an Ideapad u410 it is necessary to press the Fn key, but I changed that bios setting.)
If further information would be helpful, tell me what you would like to know.
Thanks in advance and a nice weekend,
Alfred

So, nobody knows what to do?
Or is it just a problem that can't be fixed?

Ideapad U410 Refurb from outlet - "Battery is not detected"

Hey everyone,
I recently purchased a refurbished Ideapad U410 touch from the lenovo outlet website and received it a few days ago. I charged the laptop and it says "battery is not detected" in the notification area. Once I unplug the charger, the laptop will instantly shut off and can't be used unless there is a charger connected. From what I understand, the battery can be missing, wires disconnected or faulty, or the battery is completely dead. Since I purchased it just over a week ago, I have a 21 day full warranty and another limited 1 year warranty on top of that.
I've contacted lenovo support over the phone and have been redirected in circles over 5 times without being able to get a replacement or ship it back. I don't want to remove the bottom cover either since that will void my warranty. Can someone please help me out with a direct number or who to contact? I've been told Post Sales Support is the correct department but I can't seem to ever reach it....
Thanks in advance,
Mitchell

Thinkpad X220: bad wlan connection when docked and lid closed

Dear forum
I use a Lenovo ThinkPad X220. I have no trouble with the wlan connection when i use the notebook alone. The wlan connection is also stable when i use the notebook plugged in the dockingstation with the lid open. But when I use the notebook plugged in the dockingstation with the lid closed my wlan connection drops regularely to about 2 Mbps and gets very unstable.
The ThinkPad uses the Intel Centrino Advanced-N 6205 wlan network controller:
$ lspci | grep 6205
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
The network controller uses the iwlwifi driver, that comes with the current linux-firmware package:
$ pacman -Ss linux-firmware
core/linux-firmware 20150206.17657c3-1 [Installiert]
Firmware files for Linux
I didn't change any options of the kernel module, everything runs in default mode:
$ modinfo -p iwlwifi
swcrypto:using crypto in software (default 0 [hardware]) (int)
11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint)
amsdu_size_8K:enable 8K amsdu size (default 0) (int)
fw_restart:restart firmware in case of error (default true) (bool)
antenna_coupling:specify antenna coupling in dB (default: 0 dB) (int)
wd_disable:Disable stuck queue watchdog timer 0=system default, 1=disable (default: 1) (int)
nvm_file:NVM file name (charp)
uapsd_disable:disable U-APSD functionality (default: Y) (bool)
bt_coex_active:enable wifi/bt co-exist (default: enable) (bool)
led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default: 0) (int)
power_save:enable WiFi power management (default: disable) (bool)
power_level:default power save level (range from 1 - 5, default: 1) (int)
fw_monitor:firmware monitor - to debug FW (default: false - needs lots of memory) (bool)
At first I thought, the problem could be caused by the KDE power saving settings. I changed the settings, so nothing happens when I close the lid (no hibbernation or screen lock or something like that), but without success (the wlan connection is still unstable under the described circumstances).
Also dmesg shows nothing that points out a problem (as far as I can see):
$ dmesg | grep iwlwifi
[ 19.688522] iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

[ 68.923192] iwlwifi 0000:03:00.0: Radio type=0x1-0x2-0x0
So I have no idea where this strange behaviour comes from (only wild guesses: buildfactor, antenna orientation,...).
Any help would be really appreciated.

hmmm...
how about checking both your wired and wireless nic drivers in device manager to make sure that the "allow computer to turn off this device to save power" checkbox on the power management tab is deselected.

Ideapad U410 not working in Normal Mode

Hi,
My Lenovo Ideapad U410 has suddenly stopped working in normal mode. If I need to open a link or an important document, I open it in a safe mode.
Has anyone faced a similar kind of issue? I don't want to format the system as i would first like to know the root cause. The laptop is within a warranty period however Ideapads don't have an international warramty i guess.
Any help would be appreciable.
Thanks,
Akanksha

This is cause by some conflict/defective in the installed drivers. Try doing the procedure describe in this link. It also described on how to determine which is causing the problem.

N95 WLAN Connection problems - Orange Livebox (UK)

I am trying to get the N95 to connect to the internet wirelessly through Orange Livebox (UK). I have run the WLAN wizard and the phone has identified it. I have input the WEP key and thats worked fine.......except everytime I try to connect to the net via this method I get a connection error. Has anybody else had WLAN connection problems? Can anybody help?

hi,
did you press "1" button at the back of the Livebox before pairing ?
what kind of error message do you get on the N95 ?
does it fail the same way when you go through the homescreen "WiFi scanning / Start Web Browsing" or through Tools / WLAN Wizard ?
Cheers,

WRT54GL loses Wlan connection

Hi
I have a problem with an WRT54GL Router. It keeps losing the Wlan connection. Then I have to reboot the router to get it working again.
On some days everything works fine, and the other day I have to reboot every 5 minutes.
I don´t use P2P. So there are not many simultaneous connections. Mostly there are only one or two Wlan Clients active.
Between the Router and the Client is only one Wall. Signal Strenght is at all times above 85%.
Does anyone have an idea what might cause this?

Try upgrading your router's firmware and reconfigure it from the scratch.

How to execute "netsh wlan connect SSID", but SSID has space and quotation marks?

Dear all:
I have a wifi roruter with SSID test "3"
But when I execute following command netsh wlan connect "test \"3\""
the netsh reply: 未將設定檔 "test " 指派給指定的介面。
Sorry my windows7 is chinese version, but as you can see, netsh detect my SSID as
test, not test "3".
Does everybody know how to use netsh to connect to a SSID, and these SSID has space and quotation mark both?
Regards,
Joseph

Hi Joseph,
Firstly, please modify your SSID name to make sure it do not contain spaces or special characters. SSID name is the router setting. please go there to change SSID name.
In addition, If only one SSID is specified in the profile, then the specified SSID is used to connect, and the ssid parameter is not required. If the profile specifies multiple SSIDs, the ssid parameter is required.
Therefore, I would like to suggest you run command as this syntax:
netsh wlan conncet ssid=Your SSID of the unsecured wireless network name=Your current profile name
To do this, please refer to the section “connect” in the following document:
Netsh Commands for Wireless Local Area Network (WLAN) Preliminary

5800,Wlan connection appears as 'unknown', however...

Hi to everybody!.
I have an issue with wlan connections. I defined a new access point in wireless connections, and I put it into the 'internet' destination. The access point is saved as WLAN_XX, and works perfectly.
As soon as I disconnect it, and click to find wireless connections, something rare happens. When there is high signal, the connection appears as 'known'. However if there is low signal, appears as 'unknown'. Therefore I have to configure it again as a new connection (retyping the wep password),which as a consecuence, is saved as 'WLAN_X01)'.
I updated the firmware from 31.0.101 to 40.0.005. A saved connection always showed as 'known' (even when i had not enough signal to connect) when i used the old firmware (31.0.101). I don´t know if it´s a new feature or a bug or how it´s solved, someone knows? Thanks.

This is normal. You can delete this access point from the settings and re-save it.

Satellite M70: WLAN connection lost

Hello!
I have Satellite M70 and I use integrated Intel WLAN card 2200bg. I have the latest drivers downloaded from Toshiba web site and Asus WLAN router w520g with latest firmware. Connection signal is excellent but sometimes actually very often connection is lost for 5-10 seconds.... I am downloading files all the time so there is no idle time in network traffic.
How can I inspect what is reason for losting connection?
Could authentication method or channel mode be a reason for problems?

Hi!
I updated my driver(latest one from intel website) and problem still exists. But now with Intel Wireless utility I can see error messages when connection goes down. I also opened support case to Intel about this problem. Let's see what they suggest.
I have also tested different kind of variations of configurations (power settings etc.) but no helps!
Now I am testing WLAN connection without authentication and it seems to work ok without connection lost. I will test different kind of authentication methods because i really want to see what authentication causes problems.
One thing I can say more. If I want to see connection break as soon as possible, I have to generete traffic with different kind of p2p programs and I also ping my router (default gateway) with command ping -t -l 1500 same time.

Wlan connection slow

Hi,
since a few days I have big problems with the WLAN-connection of my late 2011 13" Macbook Pro that leads to very slow Intenet Connections and Slow SMB-Server access.
In Detail: If I will open a Webpage it will take 50 times longer then from my iPad or Windows PC; and I run an Windows 2012 Server as an Data Pool, if I will access to any Remote Hard disk the Mac will need 5-10 sec. to load a Folder (the Windows PC loads it directly after the "klick").
Intristingly, If I am connected via LAN (T-based 1000 Mbit Gigabit Ethernet) everything works extremly fast.
Does anybody have a Idea to Solve this Problem? I run Mountain Lion in the latest Version, nothing has changed the System since or before the Error occured.
Thanks....
