Lenovo Yoga 2 14 Flex :: Periodically Disconnects From Network On WiFi?
Dec 21, 2009
My brand new Flex 2 14 periodically disconnects from the network on Wi-Fi. This is pretty unacceptable. Other PC's in the house are not experiencing the problem, so it's difficult to blame the router.,
I have a Broadcom 802.11N Network Adapter device with driver version 184.108.40.206, which is the latest on the Lenovo site. I am running Windows 8.1, as provided on the system. I've installed Windows updates and some other software, but have not otherwise changed the OS.
I have seen other users with similar problems, but no fixes for Broadcom.
I purchased a Flex 2 a couple weeks ago. Installed Office 365 software and Creative Cloud by Adobe. All was working well on both the networks I connect to.
Now today, performance across the entire network has gone to the dogs. At first I suspected the provider or router so went through all the standard service routines (unplug this, reboot that) over and over. Same deal, deadly slow performance for several PCs and Macs on the network.
Then I hit on the idea of shutting down my Lenovo. Suddenly the network download speed went back from 2MB/sec and ping of 2000 MS to more normal speeds.
I've rebooted the Lenovo a couple times, switched from 2.4 Ghz band to 5 with the same result.
At one point when I plugged the Lenovo directly into the modem (part of the diagnostics) the direct speed seemed faster.
Since the router is working perfectly with every other machine, and I haven't changed a thing on that, and since the symptoms go always across the network when the Lenovo is shut off, I can only assume that there is something going on with the Lenovo Flex 2 and the way it is communicating with the rest of the network.
I should also add that I tried hooking up an ethernet cable to ensure that it wasn't just a wireless thing. Still had slow performance.
Windows 8 was upgraded to Windows 8.1 Upgrade on a Flex 15.
The first time I tried to do the upgrade, I had enough problems that I re-installed from a Windows 8.1 image. All went well and all the drivers work except the Ethernet. The upgrade was relatively painless if you ignore the necessary reboots.
The latest Ethernet driver was downloaded from Lenovo and it was upgraded through Device Manager to version 220.127.116.11
In spite of Device Manager saying the Realtek ethernet adapter is working, no network is recognized by Networks and Sharing Centrewith when an ethernent cable is plugged into the Flex 15 i. The cable is good and has been checked by way of another computer.
I have previously used the hard-wired ethernet once and it worked but I do not remember where the laptop stood during the upgrade path.
This may be a hardware problem which will require mailing the laptop for the repair, or it may be a software / dirver issue. The only other thing I can do is reistall from scratch to confirm it is a hardware problem.
I have read about many issues regarding Wifi connection (connection drops often without any reason, poor signal strength, too long time to establich connection...). My problem could sound similar, but it's rather different:
Although my wireless connection appears like Enabled in Win8, I cannot switch it on / connect. It appears like Not Connected (Wifi = Off). In fact, I cannot see any wifi network when the list of available networks used to be.
- I checked BIOS, and it's set as Enabled. - I updated BIOS to the last version. - I updated wireless wireless drivers to the last version - I modified the wireless configuration as it's especified in the long forum thread for Wifi issues
But nothing has been successfull. For some strange reason, I cannot switch the wifi device on.
I purchased the Lenovo Z580 laptop last month. It is a very good laptop, very silent and well built. Coupled with Windows 8 (64 bit), its a very new experience all together, especially the uptime after restart, connectivity etc. Superfast!
I've been traveling around the world offlate and after I was back home recently, uunfortunately, I'm facing a wired problem with the Wifi since then.
Nature of the problem: After restart, sleep, turn PC on:
1/ Wifi shows full signal status at the start screen. 2/ I enter password to login and it takes to W8 start screen. I then goto the desktop mode. 3/ When I launch a browser I can't connect to internet but the wifi status says 'Internet access'. But after few seconds, I see grey wireless symbol (without any signal bar) with a star on the left corner of the wifi symbol (Not connected mode). 4/ The network I connect to is no longer visible. Only 2 networks are detected. One is an open network and the other one is a different network. Usually several networks are within the range when I'm connected to my network. 5/ After 4-5 minutes, everything becomes normal i.e. the wifi adapter connects to the network.
I've tried router/modem power cycle, disable/enable wireless network adapter and they haven't solved the problem yet. Also noticed something in the Wi-Fi Status (wireless adapter settings window) accessed via Control Panel. Speed initially was 39.0Mbps and eventually changes to 72.0Mbps, drops to 65.0Mbps...
I don't have this problem with the other laptop and tablet I own.
It can detect and "connect" to my wifi, however the moment i try to enter a webpage, it disconnects and doesn't work. So basically, the wifi doesn't work. I have checked the drivers and i'm 99% sure they're updated.
Well, didn't check before installing Macrium Reflect Professional but it detected 7 (seven) partitions in my Yoga2 13 (Not Pro) as follows:
1 - WinRE_DRV 1GB total 313MB used - NTFS Primary 2 - System_DRV 260MB total 28.5MB used - FAT32(LBA) Primary 3 - LRS_ESP 1GB total 497MB used - FAT32 (LBA) Primary 4 - NONE Unformated Primary (?) 5 - Windows OS 422GB total 44.58GB used (C NTFS Primary 6 - Lenovo 25GB total 2.46GB used (D NTFS Primary 7 - PBR_DRV 15.75GB total 12.46GB used NTFS Primary
All Yoga2 13 are like that from the factory or Macrium created some of them? If they are like that from the factory what each of the partitions have inside (other than, obvlously, the #5 Windows.)
In creating an image for restore in case one is needed which ones I should include in the image?
Is there any way to boost volume on Yoga 13?? I have my system volume and video player volume maxed out and it's STILL not loud enough. No it doesn't have anything to do with what I'm watching, and no, nothing to do with the player. Windows Media, VLC, and Divx have been tried.
I purchased a new Flex 2-15 online the past week. The model name shown on the back is "20405". Manufacture date is May 12, 2014. The User Guide refers to a "Novo Button", which is shown in diagrams as being on both the left edge and the right edge near the front. Neither location has a button of any sort. The right edge has a pinhole in the supposed button location. A curved arrow icon is next to the pinhole. I have an inkling this may be some sort of factory reset button. Lacking the Novo button, what is the procedure for accessing the features which the manual says are accessed by pressing this non-existent button?. That is, BIOS, and/or the one touch image backup/restore system?
I´ve got a problem when I connect the yoga 2 pro with my TV (8 year old sony, full hd) with HDMI. The picture doesn´t fit into the screen, it is too big. I tried changing the resolution of both yoga and tv and at the Intel graphics driver I can´t change the scaling option. H
I paid $60 just for some recovery discs to recover my accidentally formatted Yoga 2 Pro. The discs came with no instructions whatsoever, and using them is weird. First of all, there is two disc 1's, no disc 2, yet there is a disc 3 and 4. Support confirmed this is normal. There is also no prompt between discs 1,1, and 2, so despite making my best guess at when to switch, I can't confidently say I'm not screwing things up.
After the whole process completes, the bios can't find bootable media.
I had bought yoga 2 pro from Malaysia three weeks back. And I had traveled back to India last week.The PC was working fine till yesterday. Yesterday while I was working suddenly the system hangs and I had to hard reset. But after that the system didn't boot up. It shows boot device not found. I have switched it off and tried booting using restore button and opened the bios it shows that HDD not detected.
Similar kind of issue I faced two times before but if I hard boot again it worked fine.
I just got the Yoga 2 Pro and it seems like a great laptop / tablet. I have one big problem: the touchpad is near-unusable for me. It seems like I'm constantly activating the switch app gesture and just cannot use it.
How do I turn off all of the gestures on the touchpad so that it just functions like a normal mouse????
I've got a Yoga 11s which is barely a few months old and hasn't seen much use. Having the same problem - it won't power on or charge (powers on only when plugged in). In Lenovo Energy Manager battery status shows "Good" and charging status shows "Battery Connected". WIndows power management icon however, shows Plugged-in, not charging. Never had that problem before either, but it came with the power-on failure so I guess they're related.
I cannot get the Y2P to shutdown or sleep. When I try to shut down it powers off but after about 2 seconds it turns itself back on and boots up. Same thing happens when I try to sleep.I've tried pretty much everything I could find online including the following:
-Turn off wake on lan on the network adapter -Turn off auto restart on windows errors -Updated bios -Updated drivers -Disabled all non microsoft services -Factory reset of the OS
Went through every device in device manager and turned off "Allow this device to wake the computer"powercfg /lastwake (shows nothing).Shutting down isn't a huge deal as holding down the power button will eventually turn it off. But not being able to sleep the laptop when I close the lid is a deal breaker as the battery constantly drains.
I just got the Yoga 2 Pro, I also have an older Thinkpad 65W 20V AC adapter with a ThinkPad Slim Power Conversion Cable, so it will fit, but is it ok to use? All the specs match except my new Yoga 2 adapter doesn't have the wattage listed on it.
I just bought a Lenovo Yoga 2 pro and installed windows 8.1 by itsef. During Windows 8.1 initial setup I was able to use keyboard to type in PC Name, but after that the keyboard and touch pad was not working/no any response any more. After Windows 8.1 lunched the keyboard also no any response. I have to use touch screen soft keyboard. But when laptop in BIOS mode (turn power off and press a small round button next to power button) the keyboard was working fine. So I think that the keyboard hardware is ok, but some thing iwas wrong with Windows 8.1 software issue. I also un-selected all on Easy of Access->Keyboard section in Windows 8.1.
I have a Yoga 2 pro and the powered usb port was supposed to work as a charger even with the laptop turned off, but it is working just with the computer on, I already tryed to change the in the energy options the selective suspension of the usb and also in the device manager, I deselect the "computer can turn off the device to save energy" but nothing worked...
I have the issue that my newly bought Yoga 11 (three weeks ago) is charging whenever it seems to feel like. The first time I have charged it, it went up to 92 % telling me its now in power state and not charging. This happened triple. Yesterday my Yoga was beneath the 50 % mark and I plugged in the powercable, the same again: not charging. I unplugged the power cable and at 0 % and a shutdown I booted it and it charged perfectely up to 99 % without moaning. I unplugged the cable and at 77 % the same again, I plugged in the power cable and it charged up to 99 % again.
Is this a bug (battery problem) or a feature (thresholds for a long living battery)?
I recently updated my Yoga 13 to Windows 8.1 and am now experiencing significant lag when resuming from suspend and periodically while I work. Often I will type and not see the text on the screen for another 5+ seconds.
I have run Malwarebytes and Windows Defender and found no malware. By keeping an eye on the task manager I have not been able to identify a misbehaving process.
I own a Lenovo Yoga 2 Pro (Model 20266) with a stock 256GB Samsung SSD MZMTD256HAGM-000L1. It works well in general, but occasionally it'll freeze for several tens of seconds, particularly when I'm idling or working on something that doesn't use the hard drive. I thought it was an issue with the SSD going to sleep, but disabling hard drive sleep via the Windows Power Options doesn't work. I've tried installing Samsung Magician, but it doesn't support the drive even though it detects its a Samsung SSD.
Is there some setting I need to disable? Failing that, is there some way I can upgrade the firmware? This model doesn't appear on Samsung's website either.
I just got it about 2 weeks ago and it's all booger up. I think I accidentally installed some malware and it now there's stuff I just can't get off it. I've been running windows 7 for years and never had malware issues like I'm running into on 8....
Since there's no DVD drive and it didn't come with a system restore thumb drive like my mac air did, how do you do a full factory reset?
My battery is at 0% available, plugged in charging, but it never goes about 0%. I've tried resetting the battery gauge in Energy Manger 18.104.22.168 but that only runs for a few seconds and reports that the gauge reset is complete. I've also disabled the ACPI control in device manager then enabling it and the icon appears to be charging but only for a few seconds then stops. Having conservation mode on or off doesn't seem to make any difference.
The latest BIOS is installed and I believe I have the latest version of Energy Manager.
