T430s Wifi connection stability

I got a T430s from my university but I cannot stay connected to the wifi. When its connected I have 3-4 bars. It will drop and reconnect. At this point I can't go 5 minutes without the internet dropping. It has twice so far while I was writing this post. Any suggestions are appreciated. I already updated the driver and unchecked "turn this device off to save power".
Thanks!

Experiencing this problem too but with some routers only

T430 WiFi connection problem

Hello, I am new in the community. My T430 worked fine for a couple of years and now I have problems with wifi connection.
1. Instead of usual coulumns identifying the quality of the wifi connection I see red cross indicating that no LAN connection is available.
2. Wifi stops immideatly as soon as I plug the power cable.
3. Wifi connection becomes extremely unstable, so I cannot use Skype anymore.
My computer is Thinkpad T430
serial number PB********
Network adapter is:
Centrino Wireless-N-2200 (driver Netwsw00.sys)
The problem is I am out of country now and will be unable to contact computer guy till August.
Can somebody help me?

As per your query we understood that you are facing the issue with Wifi on ThinkPad T430.
To resolve the issue I suggest you to check with below steps.
Check with uninstalling the Wifi driver and update with latest driver from Lenovo support link.

A1000 Wifi connection stability issue

I just received this A1000F tablet on last Friday. The wifi connection randomly stops responding, while the notification bar show it as connected. When it occurs, router activity panel reports it as inactive. Switching wifi ON/OFF on the tablet restores the connection for a random limited time. I tried many Wifi authentication setups without sucess. My other devices as Airport Express, Acer Laptop and Sony Xperia U work flawlessy with connection staying up for days without any simmilar issue. Device has been updated to latest available upgrade (Settings > About Device > System upgrade)
Kind regards

Yoga 10 wifi connection stability / loose router contact

I use my yoga 10 on several locations where the different routers are set to the same network id/password. The issue applies to all locations (ie different routers of different make).
The yoga 10 connects well to wifi when turned on (blue wifi notification), but looses connection within a minute or so (wifi notification dark gray).
The (not so) quick workaround is to
- open settings (scroll finger from notification area) - here WLAN is green
- Turn WLAN off (gray)
- Turn WLAN on (green again)
- Close quick settings
- Wait for WiFi notofication to turn white, then blue
and browse for about a minute again - then repeat.
What makes the Yoga 10 to loose connection ?
Why does it not reconnect automatically ?
How to fix ?
PS WiFi connection is 3-4 bars, mostly 4 (=100%)

Same problem here on yoga 8, wireless routers with same SSID and password in different locations will suddenly disconnect and appear out of range. Most times I have to forget the ssid, turn off Wlan, reboot the router then switch on wlan and set up the connection again. This is not a minor glitch and does not happen on any of my other android devices, I was hoping the 4.4.2-01-021 build would fix this but no such luck. I really like the yoga 8 design but along with other stupid basic problems I.e.google maps I'm begining to think I've brought a polished turd.

Lenovo Yoga 10 HD+ WIFI connection stability issue

Same problem here but on Lenovo Yoga 10 HD+ 3G:
After a few minutes the connection is gone though the tablet shows its still there at full level. Disabling / Enabling WIFI on the tablet makes it reconnect. On the same router e.g. Lenovo Yoga 8 Wifi Edition, Samsung Galaxy S3 and S3 mini all work fine and do keep the connection. Tested with latest firmware released OTA yesterday.
Also tried the Yoga 10 HD+ on two other WLAN routers where it worked fine.
Any ideas except for buying a new router?
Moderator Note; post moved to start new thread on specific system

I'm having the very same problem. I bought a Lenovo Yoga 10 tablet about a week ago and updated it to 4.4.2 (B8000_A442_001_021_140703_WW_WIFI) yesterday and ever since then, my wifi kicks out when I'm browsing, reading emails, checking twitter etc just all of a sudden and I have to disable and re-enable my Wifi for it to work again (aprox. 5-20 minutes until I have to reconnect again). I've not changed anything in my router settings (Netgear CG3100) since the upgrade and every other computer, tablet and phones that we have in our house runs all fine, it's just the Yoga tablet where I have this issue with. I really hope an update/fix could be pushed as soon as possible since it's unbearable to use it right now and I might just have to return it to the shop in exchange for another tablet, which I don't really want (love the battery life).
Eitherway, I'd be thankful for any help/fix or responds from Lenovo.

I want to use wifi for Apple TV, but it doesn't prompt for a password, so never connects. What am I missing? Can I only use it via a non-password-protected wifi connection?

Hi - you might want to post this question on the Apple TV area - you would probably get a quicker response - if you have a specific question relating to Apple routers then post back here

My phone is not working without a Wifi connection.

I had to get a new cell phone because my speaker phone no longer works. Luckily my phone was still under warranty. Now my phone does not connect wirelessly unless I have a wifi connection. I never had to have a wifi connection in the past to receive and send email, connect to the internet, etc.. How do I fix this problem?

That surprises you?

Are you trying to say you cannot connect via your carrier's cell network? You did remember to put the SIM in?

I can not send email from my iPad . Have been using it for over a year, all of a sudden I can only receive email. I have a wifi connection in my home and have a A T &T cellular data plan?

I have a 1st gen iPhone that I just updated the software to 2.0.2
Now whenever I press the mail icon it goes to the mail app for about 4 seconds, does nothing, no loading of folders, old messages, nothing.
Then it reverts back to the home screen. Tried restarting, haven't tried restoring, thought I'd look here first.
Anyone???

On 3G we cannot send emails from either our iPhones or iPad and this also happens with some WiFi connections but not all. Yet we can always send emails from our Hotmail Email account. What is causing this and what do we need to do to resolve it?

On 3G we cannot send Business emails from either our iPhones or Ipad and this also happens with some WiFi connections but not all. Yet we can always send emails from our Hotmail Account using both 3G and WiFi.
We bought the iPhones and Ipad so that we could send emails while we are out of the Office, but we are not able to do this unless we can find a WiFi connection. Incoming emails are fine. We use IMAP, for Business emails just incase this is relevant and I know that Hotmail is POP3.
Our technical IT knowledge is not great, so we look forward to your suggestions as to how to resolve this.

Contact whomever supports the email account and get the correct Outgoing email server settings from them.

My 2012 Mini OS 10.7.5 cannot see the Ethernet connection to my Actiontec GT701 WG. The Network Preferences says "cable unplugged". The WiFi connection is working fine. Please Thank You

Never mind, problem solved. When I retunred to the Network tab the message had changed to "connected, no IP address" so I got that from the WiFi tab and configured the Ethernet manually. Have a nice day @:-)#

Toshiba EXCITE Pro - WIFI connection. Authentication failed after update

Hello.
Just received this Tablet.
Everything seemed ok while updating to the latest version (did that first to solve the heat problems).
After the last update *i lost my WIfi connection. Authentication failed* (didnt change something - was connecting - updating ok 1 minute before the last update).
After that i started testing ,Wps connection , No security Wifi etc etc.
*Finally at a random time (and with the initial settings) i got connected*. After i shut down the tablet the same problem occured.
After doing the same things again i finally got connected and this time it seems to be ok, even after i shut down the tablet.
However this is frustrating.
Maybe you have to sort this out?
I have seen and other people returning this tablet after having this problem.
It is not a hardware problem since its working ok before the update.
Of course tried factory reset twice.
Hope i dont have this problem again, *but i am informing in hope that you fix this in a future update.*

Toshiba sent me the fix for this. Figured I would use Facebook and they sorted a solution straight away.
It requires a complete reset. Not the soft reset from within Android.
I'll post it here as they will check through moderation I guess.
Thanks for sending a private message Ben. For us to get this resolved for you we would advise to perform a reset from the Android system recovery menu, to do the reset please follow these steps:
The reset process will delete any data, settings, and applications on your tablet. You must have a backup of any data you wish to keep before proceeding.
1. Make sure the tablet is off and not in standby.
2. Hold down the Volume Up and Power buttons simultaneously until the two Android icons appear.
3. Use the volume buttons to select the white box on the right.
4. Once selected, press the power button.
5. Use the volume buttons to select wipe cache partition and then press the power button.
6. Select Yes and press the power button.
7. Use the volume buttons to select wipe data/factory reset and then press the power button.
8. Select Yes and press the power button.
9. The tablet will now reset.
If you have any issues after the reset please get back to us as soon as possible!
Its been working well ever since. I guess the cache clean part might be the main one. You'll have to select the reboot yourself as I did at the end.
Might be best to use Facebook i'll see if I can find my post as the response was quick and efficient unlike their responses in here. I.e nowt from them so far.
They needed my name and serial numbers probably to log problems etc.

Yoga 8 and 10 Tablets - KitKat 4.4.2 - Wifi Connection and Notification

After upgrading to KitKat 4.4.2, some customers report that sometimes after device awakes from sleep, the Wifi connection does not resume on their Yoga 8 or 10 tablets (B6000-F/H or B8000-F/H). Also, Notifications may not show the name of the connection.
Please note that Lenovo has escalated internally on this issue. I was personally able to reproduce the Wifi Notification not showing the name of the wifi connection.
These reports originated from this thread: http://forums.lenovo.com/t5/Idea-Android-based-Tablets/KitKat-roll-out-for-Yoga-Tablets-starting-Jun...
The original thread will be closed when new threads have been opened by type of issue to assist in reporting and resolution. My personal thanks to the forums members who provided feedback to help identify post-upgrade symptoms.

I can say that the wifi had not yet been fixed. My tablet was created after the dates listed for you reported updates. Mine was delivered in the first week of April 2015, and still had hasn't ups after sleep and wifi problems where it randomly drops the connection. Can't tell when the connection has been dropped since the tablet still shows that it's connected.
Please see the link below for some of us that have come together with the same problems. We all can't have crappy Internet (especially sebum we have other devices connected that are solid) . You've responded to one person in the link, the originator, but it would be nice to see some response to the remainder of the thread. Everyone is getting to where they want to return their tablets and I'm sure you don't want to lose the money and reputation.

HT4623 What if I have no wifi connection to download software updates on iPhone 4S

I have no available wifi in order to download updates on my iPhone 4S. Is there some kind of download I can use over the 3G network to update my phone with?

No sorry to update over the air you need a wifi connection, the other option would be to update with iTunes on a computer. Remember to back up before you update.

Poor battery life and WiFi connectivity on iPhone 5s

I have bought a new iPhone 5s 16GB running iOS 8.1.2 3 days ago. The device that I have got has a poor battery life and WiFi connectivity. I have tried lots of methods given on the internet like turned off the auto-brightness, reset the phone to default settings.
Then contacted the Apple Care for battery issue. They asked for the diagnostics to check the problem. They said its happening because of the crash of inbuilt app Springboard asked me to try "Set up as new iPhone". Even after doing all these, I am still getting battery not more than 4 hours.
This is not expected from Apple. Such an awful experience on my first iPhone buying.

Where exactly did you buy this new 5S?
