Lenovo g580 Wifi new problem broadcom bcm943142hm

So week like week ago my wifi problem started the signal strat to be very low (0) or full but for like a second.
I have tried change plugs(black goes first then white?) /new drivers/change to simple broadcom to network adapter I even tried to unplug a whole card and replug it. I also tried things like Broadcom 802.11 Multiband Network Adapter but still no luck. I forgot to mention that it connects with phones with no problems and other devices connect with router without any problem so as my Lenovo not so long ago
Windows 8.1

If I understand correcly - you are getting low WiFi signal strength from your wireless adapter. Have you attempted connections with other WiFi hot spots or access points to eleminate issues with your own wireless equipment?
If you have a local wireless hotspot (internet cafe) that you can try, do so. If your wireless remains with very low (one or two bars) at all WiFi spots you try, then it would sound like your WiFi card is begining to fail. If you decide to replace the WiFi card, make sure you use one that is Lenovo branded or it will not work.
Good luck.

hi Arczi_Ghost,
Welcome to the Lenovo Forums.
From the first video, it looks like there's a problem with the Windows Loader or a system file that's needed to load but fails. Since you already re-installed Windows, this is most likely not an OS issue.
- Windows 7 Boot Process
From the second video, the flickering can be with the display (LCD) or wit hthe GPU / GPU driver. It's a bit early to tell without running some tests.
If you manage to boot Windows, can you try the following:
1. Install Lenovo Solutions Center and run a full hardware scan on the PC.
2.. Alternatively, you can also manually install the following and run a quick test on the unit.
- Lenovo Video Quick Test
- Lenovo Motherboard Bus Quick Test
- Lenovo Memory Test
- Lenovo Storage Quick Test
Edt: Fixed the links
Let me know how it goes.
Regards

Lenovo G580 - Beep Code (Problem)

Hello.
I have problem with my laptop Lenovo G580.
I buy this laptop 3 months ago without systems. I have system Win 7 32-bit and 64-bit.
Now i ahve problems with laptops and warranty service.
Laptop turns on normally sometimes and sometimes not. ( If problems shows, i cut the power off, remove battery wait for few sec, and turn on, sometimes i must do it 3 times)
It often happens that the computer will not boot just beeps.
The video below, also sometimes blink window.
Link 1: http://youtu.be/e_fbWrL0ZHs
Link 2: http://youtu.be/woviKyV7JdI
I thought that it is the fault of the firmware so I reinstalled Windows from 64-bit to 32-bit. It did not work. Flashing window appeared even when installing on a clean drive( second link, window blink on the beginning video), so I think it is rather not the fault of the firmware just the laptop PC hardware.
I sent the laptop with cinematics to warranty service and wrote back to me that "after many hour tests, there was no problem" reset bios, swapped RAM and sent him back to me.
Already two times I sent the laptop to them. Can you advise me what the problem is? What i can do to solve problem? Sorry for language mistakes. If need more information ples write in this topic.
Please help.

Lenovo G580 BIOS update problem - Error 255

Hi!
I read a lot of these problems, but there were no solutions, not even a feedback from Lenovo...
So I have the same problem.
- I download this update: http://download.lenovo.com/consumer/mobiles/62cn40ww_64.exe
- I try to run it as Administrator and I got the error message: Error 255 - TDK library initialization failed
What could be the solution? I tried the advices from other forum posts, but I still have the problem. I have Win7 x64. My laptop is G580 (20150 model).
Thanks for the help.

Lenovo G580 Video Card problem

Hi All,
I have bought new Lenovo 580G .I install Windows 7 64bit, but when I`m istalling Intel video drivers and restart system after loading and shows desktop system restart. Sometimes will load system, after that I `m istalling Gforce GT630 drivers, after restart it is the same. I tried with drivers from CD , and drivers from support lenovo. I tried with Windows 7 Ultimate, x64, and Home Premium x64 . I can`t find driver for Windows XP .

Hi
Welcome To Lenovo Community
Sorry to hear about the issues your facing. Hope i can assist. Base from you post you may need to go to the BIOS and Check if the Graphics has been set correctly. The Bios is able to set the machine to using the HD GPU or the NVDIA GPU or both simultaneously.
Also please try the latest drivers available on Support site, Please give them a try
Nvidia Video Driver
Intel Video Driver
Hope This Helps
Cheers!!!
Important Note: If you need help, post your question in the forum, and include your system type, model number and OS. Do not post your serial number.

Limited WiFi on Lenovo G580

Good morning. I work for a school district and we let students bring in their own devices. I have a student that has a Lenovo G580 running Windows 8 that can't get connected to our WiFi. We have attempted to connect to both our Guest Network (that is open and has no password) and a password protected network, and both show limited connectivity and give IP addresses of 169.x.x.x. She can connect fine at home or other locations, just not at school. Our network is fine because we have hundreds of other devices connected to it and working. I have reset her network adapter, followed the Windows 8 troubleshooting steps, and run an ipconfig release and renew (which did give me a valid IP one time, but I still couldn't get online. Every time I've tried it since has timed out on the renew). I am leery to try any updating of the network adapter since it's her personal machine and, as I said, works fine at home. Other than that, does anyone have any ideas on why she wouldn't be able to connect here? Thanks!
Solved!
Go to Solution.

With an IP address starting with 169, it means that her computer is not connecting with your router at all, not even on a limited basis. There are several things that could be causing the problem, but the easiest way is if you can run ipconfig on her machine.
Open a command prompt (all programs > Accessories > Command Prompt) and type in
Ipconfig /all > ipconfig.txt and then hit enter. Then type in ipconfig.txt to open notepad with the log. Copy it and paste it in to your next response.
But it sounds like she has her computer setup with a static IP address and because of that cannot renew the lease on the IP Address so it is reported as a 169 address. Go into the network and sharing center and click on Setup a new connection or network. Then just follow the instructions. .

Lenovo G580(20157) [Win 7] Bluetooth problems??

I have a lenovo G580(20157) which has a BCM4313 wireless chipset which supports both WiFi as well as Bluetooth, (citation here: Broadcom Chipsets)
However I can't use the Bluetooth capability of my chipset.....
I tried downloading drivers from the Lenovo website(Drivers Main Page), but it would say no driver found at the end of the installation!!
Also I downloaded Lenovo Energy Managment, and it only shows WiFi (here is a screenshot)
I also tried downloading Broadcom Bluetooth Solution but itis stuck at detetcting device:
P.S: I have a new windows 7 installation...Thanks
Solved!
Go to Solution.

hi ArchKudo,
Looking at the G580 parts (page 102 of the HMM), the Broadcom BCM4313 that the machine uses is a Wi-Fi only card .
- Link to picture
- Sample item (BCM4313 with Bluetooth)
- Sample item (BCM4313 Wi-FI only)
This may explain why you only see the Wi-Fi settings when you press Fn+F5, In this case, you may need to use a usb bluetooth adapter (like this item) to enable bluetooth functionality on the machine.

Lenovo g580 2189 driver install problem

I have a lenovo g580 with windows 8
when i try to install drivers i get some errors,any driver with other error:
smart audio hd with dolby- failure with non reason'
tuchpad ealn....-"ask for dspint package"
i download all the drivers from lenovo official web and i have energy mangement for windows 8
one more problem is in "fn" function,i dont see any fn function in the screen (no wifi,bluetooth,tuchpad,camera....)
only music. when i touch fn+f5 to turn off/on wifi the system shows on "airplane mode".
thanks

finally did it!!!! i had the same problem and now it works!
you first install the driver, and will tell no driver found ..., then go in C:\drivers\Bluetooth Driver (CyberTan, Liteon)\Broadcom\Win64 and execute Inst.exe and let it install all what it needs, don't press anything. if it still not works try install the same exe after activating bt with fn+f5.
win64 is for the one who have 64bit and I think that win32 will work for the one who have 32bit.
le: I have win7, i think it works the same for win8.. try it..
le2: and something else, I disabled UEFI from bios. I don't know if this is important, but it works for me with UEFI disabled.

My New Lenovo G580 - Blue Screen Error

Hi,
I have bought a new lenovo G580 (Intel B950/2GB/500GB) with DOS (on Friday - 21 Spetember, 2012).
I have installed another 2GB RAM in the extra slot. So, I have a total of 2+2 GB RAM now.
I installed Windows7 in it. It has worked fine for 1 day, but when I installed the G580 bluetooth, wifi drivers, it started crashing with bluescreen creating a dump file. Now I am even unable to start the system. I have formatted the system twice by could not trace it out. I have seen other forums and found out that it is due to some dropbox issues etc., But I have not installed even 1 software. As soon as I installed windows7, I started with the drivers (Drivers DVD came along with my laptop)
Please help me.
Thanks & Regards,
Sudheer K
Solved!
Go to Solution.

Hi Sudheer,
If you are able to open windows go to
Control Panel\All Control Panel Items\Performance Information and Tools\Advanced Tools and select the last option to "generate system health report" .If something is wrong with the system or a service windows will flag it for you. If you are not able to open windows and try opening it in the safe mode(press F8 during startup) check for the same.
Also try opening windows in a clean state
In the System Configuration Utility dialog box, click Selective Startup on the General tab.
Click to clear the Load Startup Items check box.
Note The Use Original Boot.ini check box is unavailable.
Click the Services tab.
Click to select the Hide All Microsoft Services check box.
Click Disable All, and then click OK.
When you are prompted, click Restart.
If this does not cause a BSOD then I would suspect there is a driver conflict/compatiablity in your system.Can you provide the exact error in the BSOD which you see?
Hope this helps
Cheers and regards,

G580 WIFI Problem ONLY at school (redirected website for wifi password)

Hi all,
I recently purchased a lenovo G580 laptop; windows 8
My laptop wifi works perfectly when I am at home or connected to any normal wifi.
It does not work when I am at school which typically once you connect to the school's wifi, it opens up a web broweser asking for your usename and password to get compelte access. (figure 1- from my other laptop)
My lenovo laptop cannot download this website, therefore I have no internet access at school since I cannot put my information inside. (figure 2- from lenovo laptop)
The problem is not my school's router because I have wifi connection on my other laptop here without any problems. Also the problem is not really the location/wifi of my lenova laptop because I can connect to my phone's personal hotspot when I am at school.
Simply, the problem is found when I cannot connect to my school's wifi because it requires me to download a site to put my information.
I have read other forums and try to figure it myself, however, I am very noobie when it comes to computers. So I appreciate a step-by-step instructions. For example, please provide links that I may need to download to update my driver.
I have called customer care, and I am not going to pay 100 bucks just to fix a simple problem. So i appreciate your time.

check whether you have set up your wifi settings correctly.(i mean 'servers' and login credentials ).

Lenovo G580 Windows 8.1 WiFi

Hi there,
I got a Lenovo G580 recently and it works all fine. Except the WiFi which is down now for a day or so. To be precise I couldn't enter the Internet after I did the Update to Windows 8.1. I deleted the Network via "cmd" and connected again but I still don't have Internet. Windows says I should restart the Router etc. and I did but it still doesn't work plus my smartphone is in the same Network and works just perfect.
Any thoughts on what I could do to solve this mess?
And I don't have any options after a rightclick on the WiFi-Network.
Appreciate all help I can get, Thanks
Robert
Hi,
ich hab mir letztens fürs Studium einen Lenovo G580 gekauft und alles klappt wunderbar, bis auf die WLAN-Verbindung, die bis zu meinem Update auf Windows 8.1 von Windows 8 auch problemlos geklappt hat. Jetzt hat er aber ständig ein Problem mit dem Standardgateway o.Ä. und schlägt mir jedesmal vor den Router neuzustarten. Hab ich natürlich auch schon paarmal gemacht, bringt leider nichts. Genauso erfolglos war ich als ich in der Eingabeaufforderung die Verbindung gelöscht und dann wieder verbunden habe. Kein Internet nur die begrenzte Netzwerkverbindung. Und wie es immer vorgeschlagen wird mit Rechtsklick auf die Verbindung zu klicken geht leider auch nicht.
Hat jemand eine Idee woran es liegt bzw liegen könnte?
Ich kann dringend Hilfe gebrauchen und bin dankbar für jeden Vorschlag!
Gruß,
Robert

Solved the problem by following the instructions of this Homepage (the comment at the end with the installing of the older driver version)

Wifi is gone after downloading or sleep modus Lenovo G580

Hi everyone,
Can someone help me with a computerproblem I have been troubling with eversince I bought the computer?
About two weeks ago I bought the Lenovo G580 laptop at the same moment as my little brother.
Now we are dealing with the same problems eversince: The Wifi connection is gone after closing the laptop and letting it go in sleep mode. The sign in the right bottom corner is still there and it says that it is connected, but when I open Google chrome it won't go any further then the homepage. My little brother has the same problem, although I also have it when I have downloaded something. I know that the Wifi is still working because it still works on my Iphone. Does anyone have a solution to this problem?

Does the problem occur when you are browsing the web also? I am experiencing wifi problem as well. My wifi connection will stop working and become Limited. Mine will disconnect every 30 minutes or so. I have to disconnect and reconnect again in order to browse the web. My computer is just 2 weeks old.
