Lenovo E530 - Accidentally deleted Intel N2230 wifi driver - sign verify error after reinstall

Hello everyone,
I had some trouble with my computer recently (HDD consistence error), which caused my WiFI driver to stop working. I tried to fix it by uninstalling and installing again from this site: http://support.lenovo.com/us/en/downloads/ds028694, it seemed good - installer said "Success" in the end, but when opening Device manager, i see that Error 52 - Windows cannot verify the digital signature of driver blabla... I have Windows 7 HP
Does anyone know how to solve this? I naively thought that drivers from official Lenovo site will be signed correctly.
Thank you for any advice, John

skrble,
Welcome to the forum. Sorry to hear about your troubles.
I re-read your message a couple times and it sounds like you are bringing systems home and that the point is that they will not connect to your home router. You have listed a good number of different ThinkPad models and noted they will not connect to your router while other manufacturers will.
Let me ask, if you take any of these ThinkPads to other locations, are you able to connect view wifi? If so, then the ThinkPad and wifi are working and we appear to have some setting / incompatibility. We have had some odd cases where routers needed a firmware update, but I don't want to jump to conclusions.
Can you please let us know if your laptops will work somewhere else first. If none of the ThinkPads work anywhere, then we have perhaps a different problem. Lastly, when you are at home, have you tried a wired ethernet connection from the ThinkPad to your router. If so, are you then able to get network access? Perhaps we can isolate this a bit.
Thanks
Mark

Wifi Driver is not working after upgrading windows7 to windows8 in MAC BOOK PRO2012

Hi,
Recently I installed windows7 in my MacbookPro2012.Yesterday I upgraded windows7 to windows8.All the basic drivers are working properly except wifi connectivity.
It is recognizing the available wireless networks,but when Iam trying to connect to my wireless router,the connection is getting failed.If I connects the Modem cable directly,it is working fine.
Is this is the problem with the drivers which were not supported by apple for windows8?

All,
Thanks.The issue is not with the driver.When I am entering my wifi Password,the default keyboard is taking as UK culture,that is the reason I am unable to connect to wifi.When I changed that to US,then i can able to connect
There is nothing to do with Apple Driver.They provided everything.

hey Alphapoint,
try this, uninstall the Wifi LAN drivers. let Windows install its generic drivers.
test your connection with the generic drivers. See if that works, then install the drivers from our support site but before you install it, go to MSCONFIG and set your unit to Diagnostic mode first before installing.

Lenovo S410p accidentally deleted NVIDIA Driver from device manager

Hello,
I "accidentally" uninstalled my NVIDIA GeForce 720M driver from my device manager when I tried to reinstall the driver. Now it no longer shows up on the device manager at all, and I cannot install any driver since the laptop does not detect it anymore.
I am running Windows 8.1 64bit on a Lenovo ideapad s410p laptop. The only graphics driver detected is the intel one. And since I'm using a laptop, re-plugging in the graphics card is not really a feasible option either...
System restore does not work (The oldest backup, somehow, is AFTER the uninstallation), and I really do not want to resort to factory reset... And of course, before the uninstallation, the driver worked just fine.
Is there any way I can force the laptop to detect the GPU again? I am pretty sure the hardware is working fine, just undetected
Please help, I have no idea what else to do at this point. Thank you in advance..
Solved!

hi Votbear,
Welcome to lenovo Community Forums!
Can you check under Drive D: if you still have the drivers folder back up
Try looking for the Video Graphics driver installer and install that.
In case you can't find the driver folder or the system does not have a D: drive
Try downloading the driver here, see if those work
NVIDIA VGA Driver for 32-bit Windows
NVIDIA VGA Driver for 64-bit Windows

Intel My Wifi Technology on Lenovo Thinkpad T400 with Windows 7

I am running Access Connection 5.62 and is able to create a wifi connection using Intel My Wifi Technology with my laptop. Other wireless devices such as iphone and laptops are able to connect to this wifi and able to obtain an ip address. However, these devices cannot access the internet through this wifi connection.
I have the Intel Wifi Link 5300 AGN card for my laptop.
Anybody knows what is the problem?
Thanks.

T61p Intel Wireless Wifi Link 4965 AGN driver upgrade

Hi,
I have T61p (XP 32bit) with wifi Intel Wireless Wifi Link 4965 AGN. Recently I tried to upgrade driver to version 13.xxxx but after installing the driver the wifi card doesn't work. To make it work I had to revert the driver to version lower then 13. Has anyone experienced this problem?
Thanks

did you download the Lenovo driver, or did you down load the driver from Intel?
Lenovo writes alot of their own drivers for things like wifi cards, its possible that by downloading Intel's driver, it isn't compatable with thinkpads.

Disk Utility erase tab for hard disk is missing after accidental OS deletion when installing Win 8.1 (BootCamp)

Hi there everyone,
This is my first post and I hope I can get this issue resolved with your help .
So the issue that I am having is that my Disk Utility is not showing giving me the option to reformat my entire hard drive.
The reason I want to this is because my Boot Camp Assistant won't partition my drive. This error comes up:
So after looking through the internet and forums i couldn't resolve this Boot Camp issue. So I decided to try and just wipe out my whole disk but as you can see I am unable to do that.
Prior to this issue, I had tried to download Windows 8.1 using a bootable USB stick and have accidentally deleted my Macintosh HD partition from the Windows install menu by opening up a terminal (fn+option+F10 was the key used to open up this terminal if I remember correctly). I was pretty upset about that, thankfully I have a backup around. Not knowing what to do I proceeded to installing Windows 8.1 anyway. Half way through the installation there was an error which I did not record. I simply exited the installer and proceeded to the Recovery System start up menu and it installed a version of OS X Lion from the internet. Then I installed Yosemite thinking everything is OK.
I decided to try to install Windows 7 now and the issue mentioned at the beginning ensued. Previously there was a disk0s1 and disk0s2 that can be seen from the Disk Utility but I could delete one of them. The other one I could only erase but could not delete the partition itself. From terminal i determined these two partitions were from the previous Windows installation attempt. The size was relatively small for both.
I ran a disk repair for the Macintosh HD volume and this error pops up:
I am using MacBook Pro (15-inch, early 2011) with:
2.2 GHz Intel Core i7

T540p battery drain in S4 state after Bios and Intel Wifi driver update

Hey Guys,
on my T540p, I configured the rapid start technology according to
http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide.pdf
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days.
I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to
https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Battery-drain-when-powered-down-Y410P/td-p...
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
How could this battery drain be avoided? Has anybody experienced the same issue?
Best,
Martin

mka1284,
you could check out devices that might resume laptop from the sleep modes and disable them. Type in the following command in the cmd line window:
powercfg -devicequery wake_armed
Also the following command will show you report about power management. Open cmd window with administrative rights and type in:
powercfg -energy.

Connecting an iPhone 4 to Intel My WiFi Technology

I have a new Dell computer that has Intel's 'My WiFi Technology' installed. This is supposed to allow wireless devices to connect to the internet via the laptop. To add a device - such as my iPhone - the program has three options: (1) WiFi Protected Setup PIN configuration, (2) WiFi Protected Setup push button configuration, or (3) manual configuration.
My question is two-fold: does my iPhone 4 with iOS 5.1 support either of the first two options, and if so, how.
If not, does anybody have an easy way to get the INCREDIBLY long and convoluted password phrase required by My WiFi Technology into the iPhone for a manual configuration.

Go to the Intel My Wifi Utility on your laptop
Click Profiles
Click New
Enter a name for the profile (mydell, whatever..)
Enter a new network name for the SSID (again, something like mydell, mylaptop..)
Click the Security tab
Ensure security type is: WPA...
Select the long Wireless Security Password string and press backspace to delete.
Enter a password (8 characters is the minimum I believe,.... such as mydellpassword1, or something)
Click OK
Click Close
On your iPhone, go to Settings>General>Network
Select Other and you should see that your mydell is offered as a connection.
Select it and enter the password you created in step 9 (such as mydellpassword1)

Error Message " Unable to start Intel My WiFi Technology"

Setup: Lenovo W520 on Windows 7 Pro
After Lenovo Software Update, the Intel WiDi was updated.
Then I run the program " Intel WiDi". I received an Error Message " Unable to start Intel My WiFi Technology"
I try to troubleshoot and did the following
1. Uninstall WiDi in the "Control Panel". However, i received an error message from Windows Installer --"Error opening installation log file. Verify that the specified log file location exists and is writable"
Any suggestions on how to reinstall the Intel WiDi

Did resolve it also! But NOT with the LENOVO UPDATE!!!
Take a look at this Intel webpage:
http://www.intel.com/support/wireless/wtech/iwd/sb/CS-031109.htm
it describes what we must do to get it running!
1. I did download the new PROSET WiFi and the WiDi driver
2. deinstall the WIDI and PROSET Wireless drivers from LENOVO
3. then intall the new drivers from INTEL in the order described above!

Accidentally clicked delete after iPhoto import

Greetings, I just accidentally clicked delete all after importing from my wifes iPhone 4s to her iPhoto library. I very quickly grabbed the USB cable out of my mac mini and the photo's are fine in the library and phone. But I'm curious about what will happen now (leaving aside the ungraceful usb dismount).I've been backing the phone up nightly both into iPhoto and iTunes. If I plug that in tonight will iPhoto remember that bad click and begin deleting the 3k images on her phone? Her iPhoto library had 8k+ images, so if that happened I can't think of how I would know which ones to restore (of course, hoping someone can tell me "that won't happen" or double your money back ) Any ideas on what will happen and/or how to recover if the worst does?
<Edited by Host>

Sorry to be a pest (here's the but);
Larry I know it's unsupported, the warning dialog tells me so "would never be done" is a -completely- different idea. Users -often- use software outside it's design parameters that's why STE and STD's lurk forums like this. I get that maybe they're not going to help me out but I'm giving them the option. Also, I grok usb, despite my mistake I've used Unix since the 80's and usb since the month it was released. Users make mistakes If I've corrupted the volume I'll take my lumps, and restore from iTunes. that's not really my question.
I'm asking about iPhoto.
iPhoto was where I clicked delete all. There's no danger of iPhone backup deleting images from my phones camera roll. -iPhoto- will interact with the phone the next time I connect it, I'm just curious if the expected behavior is for iPhoto to remember that the user clicked delete and the phone was disconnected before the process ran, and go back to catch up on the request (despite the app being quit and the machine restarted). Or if iPhoto will detect that the phone went away and say "well, I guess we'll skip that one".
I'm curious to know if anyone here has insight, if not I'll plug it in tonight (France time) and let you all know if it was easy or if I had to do a phone restore.

Probably, it seems to causing by Intel Wireless WiFi Link Adapter 's driver 'NETw5s64.sys'. The version of 'NETw5s64.sys' is 13.2.0.30. The michine installed Intel Centrino Advanced-N + WiMAX 6250. All hardware are functional.
I hibernate the machine manually, then same problem not occured.
Does a similar problem occur?
Where should I feed back?

How exactly did it occur? Did your x201 automatically go into hibernation after the defined time?
Because at my place this BSOD occurs suddenly, last time it happened about 1 minute after i was using the notebook. Trying to find analogies there ...
Win 7 32Bit though.
I disabled Multi-Core in BIOS so i don't have regular lags.
I always keep energy saving settings to "Maximum Performance" so i don't have regular contrast issues.
I deinstalled ThinkAdvantage Access Connections so i don't have random WLAN Adapter "power offs".

B5400: missing Intel wifi driver

The new (and old) driver matrices don't seem to have a B5400 driver for the Intel 7260 wifi card.
The HMM lists the card as an option, and a member reports having one in their laptop - but can't find a driver.
[edit] Several members. I'm referring them to the Intel site for drivers for the duration.
