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.

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.

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

Experiencing this problem too but with some routers only

Lenovo Yoga disables WiFi for all devices

I have a Lenovo Yoga 2 that connects fine via LAN cable, but when i disconnect and try to use WiFi it disables my wireless router for all devices. The wireless router works fine for windows phones, android phones and other laptops. The Yoga disables WiFi every time it connects - is there some setting i can change to fix this? how do i diagnose what is going on? I've checked Ipconfig /all but it looks normal. Any ideas? thanks

Sounces like the network is overloaded, or there's interference.
Try ethernet.

Lenovo Yoga 2 Pro connecting to 5ghz dual band wifi?

I just found something strange. Under Windows, my lenovo yoga 2 pro does not see my 5ghz wifi connection (from my dual band router). But I just booted under Linux Mint, and was able to connect to the 5ghz connection without issues. Any idea why this would be?

Dual Band: 2.4GHz and 5GHz at the same time:
Your MBP can connect to both.
If the Bands each have a different Name, you can choose by hand, if not it connects to the strongest signal.
Click the wireless icon and you see the name of the network you are connected to, If you see the other band name you can choose that.
Click the wireless icon in the menubar while hoding the Alt(option) key: it gives the specififcs of the band you are connected to.

Lenovo Yoga 13 WIFI Problem - making sense of the problem

Hi Lenovo
For the past 3 days i have been doing some research and observations in order to try to make sense of this wifi issue and maybe someone will come up with a solution.
Lets start
First of all i assume that when this laptop was being developed some form of testing was done before it was released, so the wifi must have worked well within lenovo offices.
Also not everyone is having this issue - some people claim no problems at all, whilst others whathever they try they can't seem to be able to fix it. Some even send their laptop for repair, other even had it replaced, yet the problem still persisted.
So the problem seems to be related to one factor - the router people are using.
Some people have a router that works well with this laptop, and so have no issue.
Other have a router that is "not compatible" with the wifi card and so no matter how many lenovo yoga 13 machines they have it will still not work.
I also noticed in my situation that when i use my android phone or tablet as wifi hotspot i have no issues, yet when i use my home router its a nightmare.
Also i noticed that chaging the way how the laptop connects to the router can make a difference;
1, At first i used a fixed IP with alternate configuration - this was horrible (continous disconnection, routers wifi crashing, takes ages to connect)
2, Then i used fixed ip in the general configuration - ths was better, yet still problems (yet disconnections were less, yet still took long to connect and at times router's wifi crashed)
3, Dynamic Ip - this is the best configuration - connects quickly, does not disconnect, yet internet connection slow and at times routers wifi crashes.
So i think its a question of compatablity with the wifi network you are using.
Also based on this i do not think this is a hardware issue - since hardware problems tend to be all or nothing - whilst in this case if one connects to a "compatable" router the connection is good.
So this is a driver issue and thus if lenovo puts some effort in this - it can be fixed - yet this doesn't seem to be the case unfortunately.
What can help from our side if everyone posts the routers and connection settings (e.g. static ip, dynamic ip etc) they are using and stating whether their wifi is working or not.
Maybe we can close down on the problem and find a fix asap.
Let me start with my configuration.
Samsung galaxy s2 and samsung note 10.1 - wifi tetharing - works fine
Belkin Pre-N router with dynamic ip and wpa2 password - problems
Ken
Solved!
Go to Solution.

I had the same problem. I came across someon that found a fix. My Yoga is restoring right now (I tried windows 8.1, it didnt work outwell) so I can't tell you the exact steps but it goes something like this.
1.) right click my computer
2.) click properties
3.) Device Manager
4.) open properties of WiFi device (under network adapter)
5.) Go to Advance
6.) there is an option to use use either 20_40w or 20w under one of the energy/power related options in this list.
(This is part I can't remember off the top of my head) - Turn to 20w instead of the variable rate.
6.) Change the Bandwith option from 20_40w to 20w.
5.) OK out till your at your desktop (might require Reboot, I dont remember)
That is how I kept my WiFi from destroying my Wireless networking in my house. I was rebooting my WiFi network hourly before.

Yoga 13 WiFi and bluetooth issue resolved

Unfortunately, I also met WiFi problems, but also found unexpected and sad solution.
Wifi worked pretty well at working place, but had problems at home. As an experiment I brought WiFi router from the working place home. It did not work!
At home I used pretty old keyboard and mouse plugged into passive USB hub. As soon as they were disconnected, problems disappeared. WiFi was also stable after I plugged power supply into the USB hub.
We are making 24-bit analog-to-digital converter that connects to the PC via USB. I exactly know its current consumption (300 to 330 mA) and know that it correctly handles USB rules about power regulations. Maximum current, specified by USB2.0 standard, is 500mA, so consumption of our ADC is within limits. As soon as I plug this ADC in, WiFi connection immediately disappears at the working place.
In the case of other devices, such as USB flash drive, power consumption may depend on the activity, increasing as it writes or reads something, and decreasing at the moment of inactivity.
I'm pretty sure that Lenovo placed their WiFi/bluetooth module on the same USB hub with right-side USB2 connector. Any device, that requires energy, being plugged into USB2.0 port, immediately destroys WiFi (and presumably bluetooth) and it is rather hard to get it back alive without special dancing around.
So, conclusion: never plug anything into USB2.0 port, if you need WiFi. This decreases number of available USB ports from two to one. Lenovo team should be blamed for that, not driver manufacturers or board manufacturers - Lenovo did non do its construction job well.
I am not sure, that all WiFi and bluetooth problems of Yoga discussed at this forum have the same reason. But in any case incorrect implementation of USB2.0 power should be considered before any other reason of malfunction.
Car manufacturers recall their products in the case of a failure. What about computer manufacturers?

Citation from Wikipedia:
The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V ± 5%) between the positive and negative bus power lines. For USB 3.0, the voltage supplied by low-powered hub ports is 4.45–5.25 V.[61]
A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. A low-power device draws at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. A high-power device draws, at most, the maximum number of unit loads the standard permits. Every device functions initially as low-power — but may request high-power, and get it if available on the providing bus.[62]
Obviously, WiFi adapter is a high-power device. If it does not have sufficient power, it will start power saving program by reducing speed. Even lower power may interrupt ins basic functions. When I connect another high-power device (HDD or ADC) to the same hub, it should get its 500mA from the hub. Seems that starting at this moment WiFi receives much less current than it requires and stops working.
If something is plugged into USB3 port, and this something does not utilize all energy it requested, WiFi starts working again.
I would greatly appreciate if somebody repeats my tests using Yoga or Yoga 2 Pro.
Test:
Reboot your system, all USB devices disconnected
Open http://www.speedtest.net site and measure Download connection speed (Speed1)
Connect external HDD to USB2 (NOT USB3!) port
Wait until HDD is connected
Test Download speed once again (Speed2)
Report results to this blog as Speed1/Speed2 couple of numbers
Thank you in advance

Lenovo V560 drops wifi connection - cannot restore without reboot

Hello,
First off let me say that I'm earning a BS in Computer Science, so I know more than most when it comes to computers, yet this issue vexes me. I only say that so that any replies understand that my level of technical comprehension is far above average.
The title pretty much says it all, I have a 6month old Lenovo Ideapad V560 that cannot maintain an internet connection. Let me describe the problem in a little more detail:
PROBLEM:
This computer can connect to any wifi, and seems to drop the connection fairly randomly, however it will drop the connection FASTER when I'm more active, such as loading multiple web pages simultaneously. That said, it ALWAYS drops the connection during a session, and NOTHING I do can restore the connectivity apart from rebooting.
This issue has nothing to do with the router, as it happens on every wifi connection I've ever connected to, school, home, work, McDonalds, etc.
I've already extensively researched the issue, so please don't reply and just start linking me to related threads, I've read them, they weren't helpful.
I've done a few things already in an effort to resolve the issue, such as:
1) Re-installing Windows 7 Pro x64
2) Re-installing wifi driver
3) Disassembling the machine, removing and reinstalling the wifi Card
4) Disabling "Allow computer to turn device off" power management settings for wifi card and miniport (all network devices, actually)
5) Removing all Lenovo "bloatware"
Again, it is not a connection specific issue, it doens't matter how the connectio is configured, it seems indepedant of that.
Any help anyone can offer would be helpful!

On topic: I have the same issue with Lenovo B560 (factory installed WiFi adapter: GTC BCM4313 M).
In the same time and the same WiFi network my old Lenovo IdeaPad Y550 works perfectly.
Is there any way to make this Broadcom (or GTC?) adapter work uninterruptable?
Currently it requires to reboot or hibernate and power on again to revive adapter.
Off topic: yesterday instead of my message about the same issue posted I have seen the following error:
Please correct the highlighted errors and try again.

Lenovo G780 Slow Wifi + Connectivity Loss

So, I bought a lenovo G780 59359250 metal Intel Core i7 3632QM(2.20GHz) 17.3" Notebook and the wifi on it caps out at 1.5 megabytes per second on a 15+ megabyte connection. I literally had my old HP next to this laptop and this laptop going at the same time. The hp was clocking in at 12 megabytes and this one was doing 1.4 megabytes.
Furthermore, when I download a bit, the wireless bars start to drop and I eventually lose the connection.
As these issues are only on the Lenovo and not the HP, the issue is not with the network, but rather with the Lenovo itself.
I've come to three possible conclusions
1. Windows 8 is doing this (unlikely, otherwise there would be rage everywhere)
2. Windows 8 doesn't play nicely with the wireless card (possible)
3. Wireless card is poor (very possible)
I was wondering what other people thought. I'm thinking about getting an AC1200 wireless adapter for this laptop. Will this possibly remedy the situation?
Thanks
I really need the speed. 1.5 megabytes + connection drops are killing me >.<.

hi nestharus,
Welcome to the Forums.
If you have the Atheros AR9485 Wireless Adapter, can you try this driver:
Drivers for Atheros AR9485 and Windows 8
Version: 10.0.0.234
OS: Windows 8 32/64bit
File: win8-10.0.0.234-whql.zip
Alternativey, does the issue happens also if you boot into Safe Mode with Networking? (if you get a stable good download then it's possible that a security software is interferring with the wireless connection).
Edit:
Using the Dink Wireless AC1200 Dual Band USB Adapter will definitely improve the performance (you may need to set it to 2.4Ghz if you only have a single band router)
regards,
neokenchi

Lenovo yoga 213 wifi card not working in the new laptop

I purchaed lenovo yoga 213 from Best Buy Boston and have brought to India.From the day one,the Bluetooth and Wifi is not working.On taking to their authorised service centr-Hitech technologies they have tried to replace the wifi card but even they are not able to solve the problem.I am trying to contact Lenovo for replacement of Laptop,but there is no response from them.What should I do?

Lenovo service centre has done all these after getting a replacement card
from Lenovo and again they have reported that the wifi replacement card
recieved is defective ,so they have asked for 2 nd time replacement of
wificard as well as the touchpad which they say carries the antenna for
wifi.The bottom line is i am tired of running around to service centre and
have not been able to use the laptop from the time i have bought the
laptop.I thought if there is a manufacturing defect lenovo,being a reputed
brand will replace the laptop.

MBP wifi "connection timeout" issue

My 2010 macbook pro has trouble connecting to many wifi networks. It works fine connecting to my network at home, but any sort of public wifi or hotel or friend's network is likely to give it trouble.
I get the "connection timeout" issue, and I know that I'm not the only one, but I didn't manage to find anything that worked from scouring this forum. Just to delinate the issue: all my other devices (iPad, iPhone, other laptops) connect fine to wifi networks in exactly the same places. I managed to find a workaround by getting a cheap wifi dongle that connects fine in precisely the same places that the MBP's built-in antenna does not. Is there any way to fix this, or am I just stuck dongling it up?

Try going into Network Preferences > Wi-Fi > Advanced. Click the network you're trying to join and click the minus button. This forces your mac to forget any saved credentials associated with that network and it will try to make a fresh connection. You can also try Network Preferences > Assist me... > Diagnostics to give you some more troubleshooting suggestions. It will probably tell you to restart your router/modem which sometimes works but you're usually not allowed to do to this to a public wifi hotspot.
It's also possible that your AirPort Extreme card, which is the part your mac uses to connect to wifi, is failing. Since 2010's are no longer under warranty, you can look up the iFixit guides to see if you're feeling adventurous enough to replace it yourself (if it is replaceable).

Wifi connection stability after upgrading to Mountain Lion on new Macbook Air, help?

Low SNR, Causing Connection Stability Issues?

Hello I'm not using the HomeHub so I cant post the usual home hub image however I shall post the one from my Netgear.
Normally I get about 5.5MB downloads so the line sync's somewhere around 6000 ish? With 4-6DB line margins, at this the line stays connected for months at a time no issues. However today my noise margin has dropped to to 0-1DB causing my sync rate to go up and rendering the line very unstable. I have tried to restart the Internet multiple times hoping this would increase the noise margin and return it to being stable to no affect. Can anyone give me a hand getting it back up to between 4-6 where my line is very stable and perhaps fixing it there?
Thanks Carl.

Hi imjolly,
We have 1 Main socket which has ADSL v1.0 written on the front that splits broadband and phone as soon as it enters. A BT engineer gave it us when he visited a while ago. Off this the router is connected to the broadband socket straight away with prob <5ft of cable (Standard stuff that comes with the homehub).
The phone side has a splitter and extenstions plugged into it however i did try unplugging them and just leaving the phone plugged in next to the master socket and it seemed to made no difference.
I will try dissconnecting the cable as you have sugested hopefully this will help.
Thanks for the help.

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!

WiFi connection/finding issues with gen 1 touch, everything else works

Hello everyone.
I am very illiterate when it comes to help which is why I am here. I will give all the info I can, in hopes someone can direct me to the right way.
I recently aquired a older gen 1 ipod touch. (Model MA623C)
It is using Version 2.2.1 (5H11)
when I tried to update it, it told me it was updated.
We use wireless here at the house for our PC, laptop, 3 gen4 ipod touches and an iphone 4S, all of which are working find and on the secured network,.
When I turn on my gen 1 ipod and go to settings, the secured network that everything else is connected to, for the most part doesn't even show up, (under the choose a network) and when it does show up in the list for me to choose from, it only shows 1 bar. I type in my password and it says unable to join.
I am not far away from the main station. I moved to many different places in the house and IF it decided to show up in the list it is just one bar and will not join,
I have turned off the iPod, I have unplugged the router, I have reset the network settings but that is as far as it goes as I have no comprehension of DHCP, BootP or Static or anything about the HTTP proxy being off, manual or auto.
I notice if I look at one of the other ipods it has numbers bu the subnet mask, router, and DNS. I cannot get anything like that to appear on the gen 1 I am working on.
I am good at following directions but again, very illiterate when it comes to this sort of thing.
I am leaving on a plane trip with my son on Thursday morning at 5am, (i would like him to have some use out of this lol)
if there is anyone that can take me under their wing and help me along it would be appreciated.
I work 7am-3pm (central time, Tuesday) with little to no access to this forum until after then, but I will return and see if help has arrived.
Many TIA
TRIE

Try restoring the iPod via iTunes. First from backup and then to factory settings/new iPod. See:
iTunes: Backing up, updating, and restoring iOS software
If you want, you can update the iPod to iOS 3.1.3 that you get here. You have to pay for it though.
Purchasing iOS 3.1 Software Update for iPod touch (1st generation)
If still problem you may have a hardware problem like a bad connect to the antenna. You can make an appointment at the genius Bar of an Apple store.
The 1G iPod only use the B and G wifi bands. It will not see N bands.
