Thinkpad T440p unstable wifi connection

I purchased a Thinkpad T440p during last Christmas. I always have unstable wifi connection. I have updated all the drivers, changed to different wifi enrionments, and restored my laptop to factory conditions. Still, it is very unstable. Anybody here can give out possible solutions? I know I am within the warranty period. But I am using laptop everyday, and don't want to ship it to Lenovo for a long-time fix.

Try this driver?

VERY unstable WiFi connection Xperia Z2 5.0.2

Hello,
For some reason my wifi connection is either very slow, or there isn't any connection. And when it does connect, it is REALLY slow, and then it drops.
I get really frustrated because on my other devices such as an asus notebook and a Samsung tablet it works like a charm.

I notice the same thing with the latest firmware (28) sometimes while connected to my home wifi network. When I'm outside, my phone will show a full connection, or 3/4 bars, but there's no Internet access. If I toggle wifi off and on, it sometimes kick starts it, sometimes doesn't do anything. When I'm inside, I have no issues. It's almost as if the wifi icon is buggy. As if it doesn't show a true reading of the wifi signal strength.

Unstable WiFi connection to PS3

hi,
i've already seen some posts in relation to similar issues but couldn't find a solution: i'm running a 2gb time capsule as wifi router in my network with an old macbook and powerbook, 2 iphones 3gs and a ps3. All running most recent firm/system software.
it seems that the tc randomly terminates the wifi connections to any device connected, however there is no regular pattern. below is an extract from the internal log which in such cases records a "disassociation with station" for unknown reason - at least i have no clue. can someone help, please (unfortunatelly apple care wasn't of any help).

Welccome to the discussion area, Dominic!
With the explosive growth of wireless networking and other wireless devices like cordless phones, it's unfortunate that wireless interference is causing so many issues for users.
You are probably picking up interference from another nearby wireless network, security system or cordless phones. Because of the intermittent nature of your issue, cordless phones might be the first suspect since conversations start and stop. Most cordless phones operate on the same 2.4 GHz frequency that most wireless networks use. I had to get rid of mine since they were causing too many problems for my wireless network.
To give you an example of the difficulties that cordless phones can cause, my neighbor...across the street...can literally bring my wireless network to a crawl and sometimes a crash if he's in his front yard talking on his cordless phone.
If you have cordless phones, keep them as far away as possible from any routers or computers. You won't be able to do anything about an offending phone at the neighbors, unfortunately.
All you can really do is experiment and try different wireless channels on your wireless router to see if you can find some clear airspace.

Very unstable WIFI connection on Satellite A200 PSAE4E

Just had my A100 Equium replaced with an A200 satellite pro and for some reason I am struggling to get it connected to my WiFi network. I had the old laptop connected fine and was using channel 11 on my WAP.
Now having tried to connect my new laptop I am finding the connection very unstable. I have tried different channel numbers and these have worked mainly the lower numbers, but have proved slow and unreliable. I have other laptops which are fine using my WAP on channel 11.
Anybody else suffered this trouble and what's the solution.
Netgear WAP wg602. No firmware upgrade available

Hi mate
I believe that you known very well that its not easy to say exactly what could causes this WLan interruption.
As far as I know this notebook was delivered with Vista OS. I have read that the Vista OS need to be updated to the latest state and Microsoft patches and fixes must be installed to fix different Wifi issues.
Note that the patches must be updated using the Microsoft update website!
Furthermore I would recommend updating the WLan driver and to check if there could be an compatibility issue between the internal minPCI WLan card and your WLan router. You could also try to check if the WLan works fine without any additional encryption settings.
Best regards and Happy New year ;)

Unstable WiFi connectivity in macbook pro (Retina, 13-inch, Late 2013)

Hi guys!
My macbook pro is connected to the internet via WiFi router, and it very often it happens that my macbook loses connectivity with it. WiFi logo shows the same signal strength, but all browsers (Safari & Chrome) can't load webpages.
This issue can be solved by turning WiFi on and off, but it happens again and again. It looks like connectivity loses when Macbook goes in sleep mode and get's back from it, but sometimes connectivity issues happen even without sleep mode switching.
I found in the internet that this issue can be solved by turning off Bluetooth and tried, but it didn't help.
I totally understand that from one point of view this issue is not a big deal, but we are speaking about Apple device, and before I thought that this brand is synonime for ultimate quality and reliability. So please help me with this issue and bring back my faith in Apple;)

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

WiFi connections are unstable on multiple different WiFi networks

Has there been any updates on the unstable WiFi connection issues with the Note 3? I have this issue with multiple different WiFi networks even though signal strength is not an issue when it happens. I picked up my Note 3 in August/Sept 2013.
1. Work WiFi
2. Home 2.4G channel and 5G channel
From what I have searched so far, I am by far not the only person with this issue, but I have yet to see a fix or any kind of legitimate input from Verizon on this issue.
The issue even happens in SafeMode so I know its not an app that I downloaded that is causing this issue.
Thanks

Samsung is aware of the issue. The fix is supposedly with Kit Kat.
They may suggest you going to a Best Buy mobile and have the software removed and put back on. Been there done that, didn't work.
Sending a replacement out isn't going to help. It is a known software issue, and it will continue until there is a build that fixes the issue. IE: Kit Kat.
You should have the MJE build. This software is the problem. MJ5 was no problem. If you get a replacement MJE should be on it, if not as soon as you put the SIM card in it will start to download it.

!TRIED EVERYTHING! PLEASE HELP! Lenovo thinkpad twist super slow WIFI connect to home router

I love my twist i just wish my wifi would work at home!
It connects and works fine at public places
At home it takes forever to connect maybe have to try 5 times taking 5-7minutes and it will disconnect sometimes if computer goes black
I have : lenovo thinkpad twist s230u with windows 8
I have a : Broadcom 802.11n Network Adapter
I have a : Broadcom driver 6.30.59.26
Troubleshooting that i have already tried: adjusting wifi power settings, downloading lenovo driver
PLEASE HELP

I would try plugging the laptop directly into your cable modem, thus by-passing the router, and check your connection speed. Next, connect the router to the cable modem and plug the laptop directly into the router by cable. Compare your connection speeds. If both work fine by cable, then I think your wifi on the home router isn't broadcasting/working. You say the wifi connects at work/public, which leads me to believe it is not your laptop wifi card. What is your wifi signal strength from your home network? work? public?

Why my wifi connection is unstable? I have an ipad 4 wi-fi and my net connection only works very close to my router!

My wifi connection only works well if i am really close to my router. My notebook connection runs great either close or far from the router! What can i do about that? Thank you!

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

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...

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.

1st generation Time Capsule - unstable internet connection

Hello,
I just bought new mac (iMac 27') and Time Capsule (1st generation firmware 7.6.3) When i connected Time Capsule instead my old router, internet connection is very tricky. When my iMac is connected by Lan cable and Wifi on mac is off , everything is fine. But when any device (iPhone, iPad) connect on wifi, internet connection becomes very unstable (including iMac on lan cable!!!). But wifi connection inside my network seems ok (i can use time capsule with no problem).
In the AirPort utility is the "pilot lamp" near the Time Capsule still green. But between Time Capsule and internet change green and amber color every 30 sec (estimate).
I tried both (2.4 and 5 GHz) WiFi but with no solution. When i use my old router, everythink is ok. Or when I unplug all WiFi devices (WiFi router on time capsule can still runs) and my iMac is connected by cable, everything is ok too.
I don't know if is it known problem, but i guess it can be hardware trouble.
Thank you for any answer
Jan

Ok, that is Gen4.
And the fault is unusual.
I recommend a full factory reset.
But downgrade the firmware first. 7.6.3 is known to be problematic. Simply hold down the option key whilst you select version in the airport utility.You can only go back to 7.6.1 though.
The quick method of factory reset.
Power down the TC.
Hold in reset. and keep holding it in. Gently it is a tiny surface mount switch with a plastic lever.. Attempting to push it out the other side of the TC will not make the switch turn on.
(I fix TC and have several reset levers bent over and jammed).
Power on the TC.. this needs three arms.. a friend or power switch you can get to with your feet..
Keep holding in reset for about 10sec until the front LED flashes rapidly.
Release reset and wait .. the boot will be slow as it deletes previous setting.. only from router side and pulls out the factory defaults.
Setup wireless and TC with short names .. no spaces and pure alphanumeric. Use different name for 5ghz.
I also recommend you install the old utility so you can access the TC log.. the new v6 utility has no log access.. so you are completely without clues as to what is happening. Not that the log is exactly helpful but it is worth a look.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.

4.3 upgrade issues - battery drain, unstable WiFi, freezing, wake-up lag/freeze

I've been (also) experiencing issues since my Galaxy S3 was pushed the 4.3 update on the morning of 1/11/2014. The worst is the battery drain - losing more than 50% of battery life within 4 hours of 100% with only minor texting during that time - with the charging process taking nearly 3 times longer to fully recharge. The moment it's removed from the power cord, it drops to 98%. This was not happening before update.
Today, I called Verizon's technical support who recommended a factory restore. Since I read endless posts/experiences of this not resolving the issues, I chose not to take that path and to work with Samsung to understand when a fix would be pushed. After 45 minutes on the phone with Samsung explaining the issues as if they'd never heard of such problems with the update - I was told that I clearly had water damage to my battery which was causing all of my issues. Sure, and everyone else who owns an S3 in these forums has the same water damage. Of course, the moment I asked to speak with the Samsung rep's superior, our phone connection grew dim, sputtered as if it were a bad mobile connection, and suddenly disconnected.
I experience the "Unstable Internet Connection" to WiFi when no other phones have issues with these networks. They're the same networks I've always used - but since the update, they're now "unstable".
The lag to wake up when I receive a call or text sometimes takes 10 swipes and a few freezes before it finally unlocks.
I've downloaded no new apps since the upgrade, yet apps I used regularly prior to the upgrade now randomly freeze on me, requiring me to remove the battery to restart the phone.
Unless Verizon is willing to let me out of the 2-year contract since I'm not able to use my phone in the manner to which we'd agreed in that contract, they had better start acknowledging a large-scale problem with this update and work dilligently with Samsung for a speedy resolution. Just seems odd that this update was pulled back in November for these exact issues, yet Verizon chose to allow it to be pushed to their S3 users in January without resolution from Samsung. Gee, wonder if it's so we'll all upgrade to the S5 as it's release is a few months off. Hmmmm.
http://www.sammobile.com/2013/11/18/samsung-delivers-official-statement-regarding-galaxy-s3s-android-4-3-update-issues/

I agree, the upgrade is awful. All I can do is complain publicly and if all of us do, maybe something will be done sooner.

Ipad mini retina ios 8 update - useless wifi connection

Hi,
I updated my ipad mini retina display to latest version of ios 8 yesterday. What a disaster that turned out to be - since updating wifi connection to my BT homehub 5 router has been terrible. It will work for a few minutes then the connection just sticks - it not the router as iphone 5 and laptop work perfectly with it.
Tried a hard re-set, re-setting the network settings & finally reset to original setting - same thing happens.
Anyone help me with this? I so wish I'd never run this update and stuck with ios7 - presumably there is no way back??
Thanks

Hi,
Same issue here, unstable connection since I updated to iOS 8.0.2, I need to turn off/on the wifi when it happens. That is not a router issue as my other devices work perfectly (iPhone 5 with iOS 8.0.2 by the way)
I already restored my iPad min three times in vain !
Waiting for for a fix, that's all we can do but it's very frustrating and disappointing !

Unstable WiFi on NB200

I have a recently bought NB200. I have 10Mbit Virgin Media (Cable ISP) into my house then to a wireless router. The connection is completely problem free via my iPhone, iPod Touch and other laptop.
However, when connecting via this new nb200 it is unstable. The connection may be fine for hours, or break mutliple times within minutes. When the connection breaks my wireless connection within Windows shows as being fine, with Excellent signal strength.
The only way to repair it is to reboot, or run the Windows Network Diagnostic Utility, which reports that nothing is wrong, but somehow repairs the connection....
Please help as this is driving me crazy. If this cant be resolved the machine will have to be returned I think.

Hi
Its not easy to say why your WiFi connection is unstable
First of all I would try to update the WLAN driver. Latest version can be found on the Toshiba website if you search for your model (NB200). Download and install it.
Make also sure that your BIOS version is up to date. You can get it on the Toshiba website too. Sometimes I can read here that WLAN connection works stable after such an update.
Last but not least try updating the firmware of your router. I had a similar issue that WLAN connection wasnt stable but after firmware update it was solved. You can get it on the manufactures website.
Good luck! :)
