Problema conexión wifi lenovo G50-70 wnidows 8.1

Salud comunidad! Soy nuevo por aquí... Tengo un problema con la conexión inalámbrica, de hecho, no me aparece ninguna red disponible. Os expongo la situación por ai alguien pudiera ayudarme: Trabajamos en una oficina, y compramos dos portátiles LENOVO 50-70 en agosto de 2014. El sistema operativo es windows 8.1La cuestión es que han funcionado perfectamente los dos portátiles hasta ahora, que solo uno de ellos tiene este problema de conexión wifi a internet y a otros dispositivos. No aparece ninguna red disponible, mientras que en el que funciona bien, que está a 5 metros, salen unas 12 redes disponibles.Hay algo que me parece extraño y es que cuando intento solucionar el problema me sale solo la posibilidad de conectar el cable ethernet, pero no menciona nada de opción wifi. Antes de meter la pata intentando arreglar el problema, interpretando todos los mensajes que me salen, y sin mucho conocimiento, espero que alguien pueda echarme una mano. Gracias de antemano.

Gracias Jorge, He seguido los pasos que me indicabas. He ido al administrador de dispositivos, y en adaptadores de red, aparece la opción Realtek PCIe GBE Family Controller, cuando cliqueo esta opción se desplega un cuadro de Propiedades, y ahí, en Opciones avanzadas, aparece como primera opción: Propiedad 'Activación con LAN de apagado' y Valor 'Activado'; y en la pestaña 'General', aparece en 'Estado del dispositivo' el siguiente comentario: Este dispositivo funciona correctamente. Crees que aún así, con lo que te he descrito anteriormente, necesito descargar el driver? incluso cuando ha funcionado correctamente todos estos meses? Sigue siendo tu sugerencia llamar al servicio técnico de la garantía? Gracias.

Wifi and Camera not working on Lenovo G50-45 80e300rgin

I bought the laptop Lenovo G50-45 80e300rgin and installed Windows 8.1 on it. The problem is that when i launch the camera app it shows that 'No camera found' whereas the camera driver was installed successfully. The other problem is that there is no trace of wifi when searching for it whereas wifi is turned on from the BIOS and the laptop is not on airplane mode. I later disocvered that Device Manager shows no wifi device. Please Help!!

hi priyamdubey ,
Welcome to Lenovo COmmunity Forums!!
Do you have any device under device manager that has a yellow symbol? as it may be the wireless without proper driver.
If the Wireless device is really not showing under device manager and it is on on BIOS, then it is a detection issue. the Wifi Device may not be physically detected by the computer,
Try restoring the bios to defaults by hitting F9 then F10 to save and exit.
The same might be happening to the Webcam

Lenovo G50-70 Bluetooth/Wi-Fi problem in (32bit) window 7

hello , recently i installed window 7 32bit on my Lenovo G50-70 laptop with window 8.1 (64 bit) installed (as default).
but found bluetooth and wifi not working
I downloaded 515mb driver file from http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-70-noteboo...
After unpacking I get a Atheros, Broadcom, Realtek, Inte folder with "Setup.exe" file and when I'm trying to use it there is only a "Warning" window with message "No Appropriate Driver to be installed"
I checked BIOS settings too - there's also Wi-Fi enabled

hi Nitesh,
The "No Appropriate Driver to be installed" error usually pops up if the installer can't find the specific hardware ID(s) to install the necessary drivers. This may happen if you have a different type of bluetooth adapter (eg. Intel wireless +bluetooth combo)
Can you try the following:
1. If the Network Controller (wireless adapter) is present under Device Manager, can you install these drivers first and reboot if necessary:
Lenovo Energy Manager
21.4MB
WLAN Driver (Atheros, Broadcom, Realtek, Intel)
267MB
2. When finished, check if you can now see the wireless and bluetooth adapter under Device Manager (see Bluetooth and Network Adapters) and press the airplane mode key (F7) to enable these devices.
- Sample Image
Let me know how it goes.

Lenovo g50-30 won't connect to home wifi.

Hello everybody, I just signed up to find a solution.
I got a lenovo g50-30 with windows 8.1 about three weeks ago, and I've had a wireless problem ever since. The laptop will connect to my wireless router (Thomson tg582n) but then it shows the limited connection alert. I can navigate for about 5 minutes but right after im unable to do so, while the rest of smart phones and tablets can connect to it. This issue began about five weeks ago with and old macbook I had, but it doesn't seem to have a fix. In college I'm able to connect to the wireless networks without trouble and Ethernet works fine as well. I've tried everything, restarting and restoring the router, changing channels and security encryptions, established the same IP address, I disabled, restored and enabled windows firewall, released and renewed IP, flushed DNS. Disabled and enabled WiFi adapter, uninstalled the drivers and installed them back again. I've seriously done everything I've found without success, so I come to you in desperation. It would mean the world if you could help. Thanks!

THANKS SO MUCH FOR THE HELP (mind the sarcasm)
Anyway guys, I found a pretty good solution that ended my connectivity problems. Just go to your wiifi configuration and properties and choose to stablish a custom DNS server, then type 8.8.8.8 as main server and 8.8.4.4 as the secondary one (These are Google's DNS free servers) And all of your problems will go away. If anything, feel free to ask.

Graphics display problems (dialog boxes) Lenovo G50 AMD A6 Win 8.1

Graphics display problems Lenovo G50 AMD A6 Win 8.1 Greetings to all. After having spent a number of days trying to find a solution to a display problem, I turn to this forum for help. I own a Lenovo G50 AMD A6 Win 8.1 ever since November 2014, and have had display problems ever since the first day, be it while using internet (Firefox or Explorer) or various software (Text editors, etc.). Many dialog boxes, including colour settings and controls (open, close etc.) either have an inappropriate appearance or even do not appear at all! I manage to "click" on the right places using memory: most areas are INVISIBLE! Another example would be that I do not see any backround colour or image on most webpages such as this one).  Some suggestions included checking for graphics updates (but the drivers used were already up-to-date).  I 'd be most obliged for any new suggestions. Thank you very much. George

Greetings to all, I finally decided to express my utmost discontent with- the Lenovo G50-45 I bought before Christmas 2014,- the summary response with inappropriate links that I received after exposing my problem- the fact that I tried to dowload the following graphics driver  (Beema) AMD Driver (VGA, HDAudio, SATA) for Windows 8.1 (64-bit)
exe
526 MB
Windows 8.1 (64-bit)
VGA V14.502.1002.1002-Logo'd_HDAudio v9.0.0.9905_SATA v1.3.1.220;VGA v13.302.1601.1001_HDAudio v9.0.0.9905_SATA v1.3.1.220

I find it quite disrespectful to NOT provide customers with EASY support, as well as avoiding to answer their requests for further help when some simplistic "assistance" that one can find almost anywhere on the web leads to no further solution. I shall not repeat the problems I have faced till now: vide supra. The problem, however, is NOT just with browsers.I simply cannot see any dialog box content and colour in MANY software programs, such as OPEN OFFICE; for instance: PRESENTATION colour dialog boxes show BLANK squares instead of squares filled with different colours. This has occured AVER SINCE DAY ONE! Finally, a new bug has appeared: Windows 8.1 keeps popping up some email program to which I am invited to register - I never created a Windows email account, and certainly don't intend to do so.NOR shall I accept some "Lenovo Service Bridge", however "discreet and inoffensive" it might be. I don't know if there are any legal grounds for customers to complain for all these problems. I DO know, however, that I shall NEVER buy a LENOVO device ever again. The pricing and processor might be competitive => yet, the support that ensues is, as far as I'm concerned, LAMENTABLE. To make a presentation, I have to switch to a Samsung R20 using XP..... What is the meaning of all this? George

Lenovo G50-80 80E501E9GE - WLAN Probleme

Hallo, ich habe mir vor Kurzem einen Lenovo G50-80 gekauft. Installiert ist das Betriebssystem Windows 8.1 (das war vorinstalliert). Ich habe von Anfang an Probleme mit dem WLAN. Immer wenn der Laptop in Energiesparmodus oder nach dem Herunterfahren, neu hochfährt, erkennt er die WLAN-Verbindung nicht, obwohl diese mit automatisch verbinden hinterlegt ist. Hier erscheint immer die Meldung Verbindung begrenzt. Erst nach Ausschalten des WLAN Routers erkennt der Laptop die Verbindung. Es kann aber definitiv nicht die Lösung sein, jedes Mal den Router neuzustarten. Ein Laptop in dieser Preisklasse sollte eine automatische Verbindung ohne Probleme drauf haben, mein alter Toshiba läuft ohne Probleme mit meinem WLAN Router. Bitte um Hilfe oder Angabe ob ich den Laptop in Reperatur geben muss. Das Programm Fehlerbehebung brachte auch keinerlei Erfolg! Grüße

Hallo Laptop2, willkommen im Community-Forum.
Der Vergleich mit anderen Geräten ist immer etwas vage, da das WLAN-Modul, die Treiberversion oder der Stand aller Systemdateien völlig unterschiedlich sein kann. Außerdem fällt oft die Kompatibilität zwischen Router und WLAN-Modul unterschiedlich aus.
Im ersten Schritt würde ich den aktuellsten WLAN-Treiber von Lenovo installieren:
http://support.lenovo.com/de/de/products/laptops-and-netbooks/lenovo-g-series-laptops/g50-80/downloads/DS101669
Schau dann bitte, ob die Tips aus diesem Artikel helfen:
https://support.lenovo.com/us/en/documents/ht080645
Was du weiterhin testen kannst:
- die Bandbreite des WLAN-Adapters fest auf 20 oder 40 MHz einstellen (wieder über Rechtklick auf das WLAN-Modul im Gerätemanager -> Eigenschaften -> Erweitert)
- den Echtzeitschutz des Antivirenprogrammes testhalber einmal deaktivieren / pausieren. Eventuell ein Update durchführen oder auf ein anderes Programm auweichen.
Gruß - Sebastian

Lenovo G50-30 RAM Bank Problem

Okay so I purchase an additional 4GB of RAM to stick into the laptop as i've read there are 2 RAM slots available. Ran a Speccy scan - also said 2 memory slots with 1 free memory slot. After taking off the back cover, I see Slot B is already in use with 4GB of RAM. There is a Slot A empty. But there is no bank to stick the RAM into. There is only a bank in Slot B - which would be the slot furtherest north directly on top of Slot A. Now why are there two slots but only one bank? Is there somewhere else that can take the extra RAM? Or so I just return for a 8GB piece of RAM? I've read on numerous sites that this laptop has two slots. But seems only one is capable of having RAM inserted into it?

Hi Geronimofinch,
Welcome to the Forums.
As per the query we understood that you are facing issue with RAM bank in your Lenovo G50-30 laptop.
As per the specification this model has 2 RAM slots, you can refer the manual 2 RAMs can be fitted to this system.
Click here for the manual and refer page number 41.

Lentitud, conexion limitada lenovo g50-70

Buen dia ante todos ya llevo 4 meses con una lenovo g50-70 y la verdad hasta ahora estoy decepcionado de la marca primero que nada se pone lento incluso lograr colgarse por estar haciendo tareas sencillas como tipear un documento en word eso sin contar cuando navegar que tmb se pone lento entro al admnsitrador de tareas y observo que el disco duro trabaja en 100% nose si eso sea normal, Aparte la conexion por wifi esta PESIMA a cada rato se muestra CONEXION LIMITADA , ya descarte que sea el router porque tengo otros equipos que tambien estan conectados al wifi y normal funcionan abra alguna solucion y abra alguna forma de optimizar el ordenar porque esa lentitud me esta molestando demasido

Antes de pensar que no es un problema (físico) de disco duro intenta esto:atajo teclado Windows + i /sistema,
Averiguar si un programa es el problema, en estos casos el primer culpable es el antivirus, mantienes el antivirus de fabrica? o algún programa pre-instalado.
El CDI es un software de diagnostico no confiable a un 100%, problemas de fabrica (físico) del disco duro.
Un saludo.

Distorted microphone with Linux mint in Lenovo G50-70

I have installed Linux Mint 17.1 in Lenovo B590 and microphone works perfectly. I installed Linux Mint on a new Lenovo g50-70, microphone works low and very distorted.
I've adjusted pavucontrol and I deleted to zero right channel mic, works perfectly for seconds but settings are deleted for auto adjusting mic and right channel is activated again. Then microphone works with distortion again.
Thank you for your attention.

Hi roberto-
Yes, its a shame. I have also contacted lenovo support hoping that they can sort out this problem. However, first response from them was 'contact your internet service provider since internet connectivity goes down'! :-/ I am hoping I have been able to get through to them now at least about where the problem lies. I wonder if anyone has tried using the laptop with the same broadcom wireless adapter with some other version of OS (linux, windows 7 etc.) and whether they still face the same problem. I haven't tried that yet. If this is just an OS / driver issue I hope someone somewhere is working on a fix! If not, I guess the only other solution would be to get an external USB wifi adapter but that is not something one would want to do when you buy a brand new Lenovo laptop. This was a big let down for me.

Lenovo G50-45 Wireless has dissapeared completely

I have a Lenovo G50-45 that when i bought it worked perfectly. Here recently it seems the wireless adapter has magically vanished and i say that because ive done everything i know to do and ive searched google everywhere but no one seems to have the same issue i do except one person and he was running linux and was able to resolve his issue. I on the other hand havent been able to.This laptop has a bluetooth/wireless card combo. The card handles both connections. The laptop itself has a AMD 8 processor, 4GB ram 1TB HDD running windows 8.1Oneday the laptop just wouldnt connect to wifi. I work on computers alot, and short of replacing the card itself i havent found the solution on my own.The wireless adapter does not show up in network sharing when you click change adapter settings. Only the LAN and bluetooth connections are there. I checked in device manager and there is no missing or improperly installed hardware. Opened the network connections in Device manager and there is no wireless adapter, no WLAN, no wireless anything avaliable there.I have done the following:I uninstalled and reinstalled the bluetooh driver. updated the bluetooh driver. physically removed the card, started the laptop (the bluetooth connection dissapeared like i expected, turned off the laptop and reinstalled the card and restarted, the bluetooth connection reappeared but not the wireless.I checked in the BIOS. Wireless is enabled. I updated the BIOS. Restored defaults. Still no wireless card.I thought maybe there was an issue within windows 8.1I partitioned the HDD and set off 100GB and installed Windows 7. I didnt think id be able to install the card but i wanted to see if windows 7 detected the hardware. It actually installed the bluetooth card by itself and properly, with an out of date driver im sure but it recognized it.But it did not find the wireless adapter. No wireless card in Device manager in windows 8.1 or a fresh install of windows 7.I ignored that the card wasnt there, and i went to the lenovo site and downloaded the proper up to date drivers. installed them on windows 7 and 8.1. I get the following error message "No appropriate driver to be installed"Now i have a feeling the card itself is to blame. Maybe i have that one card that just wasnt gonna make it. Ive never had a wireless card burn out on me ever but i suppose it is possible. But before i go buying parts, even though its cheap i dont have much money. And the principle of it all, if the card works why should i buy another one? right? its a disgrace to say i work on these devices and be beaten by one of them. So has anyone had a similar issue? Something i havent yet tried?I would just throw in a wireless adapter i have here but the port on the motherboard is different than what i see in most laptops, i assume because its both wireless and bluetooth. I only have wireless cards laying around, non of them fit properly so i will need to buy a replacement to test. But if anyone can help me out, id appreciate it.

Hi Kris_hm,
Welcome to Lenovo Communtiy Forums!
Normal Troubleshooting path on this cases includes
Power Cycle of the system
Checking of WLAN in BIOS if Enabled (Includes resetting BIOS to defaults)
WLAN card reseating (Removing WLAN card and reconnecting the WLAN again) Includes cleaning of the ports and connectors.
If these are all met - You might need to replace the WLAN card,
The WLAN Card socket supports M.2 / Ngff Connection type
Make sure you get a replacement card that is on this Maintenance Manual WLAN list and has an FRU tag.
This is to avoid getting whitelist problem

Lenovo G50-30 Unable to access BIOS settings after Windows recovery

Hi
I recently 'downgraded' a recently purchased Lenovo G50-30 with preinstalled Windows 8.1 to Windows 7 using a UEFI USB install on a GPT partition. I also updated the BIOS from A7CN40WW to the latest A7CN43WW and all was working fine. However, after performing a necessary restore of an system image created using the Windows 7 backup and restore tool, I am suddenly unable to access the BIOS settings, either with the novo button (I do get the menu to select BIOS) or with Fn +F2. All that happens is that I receive a blank screen with a static cursor in the upper left corner. I can however still access the boot menu Fn +F12. This is a particular pain as I obviousl can't select USB 3.0 in BIOS.
Any help here would be greatly appreciated.

OK, I managed to clear CMOS by disassembling and desoldering a leg off the the RTC battery but to no avail. The problem seems to be that BIOS a7cn43ww itself has somehow been corupted. In theory this should be able to be resolved by a reflash. The trouble here is there seems to be no way to reflash with a current or previous BIOS version, so I'll have to either wait for a newer version or someone may know better.
C'mon Lenovo support this simply isn't good enough. It's a brand new laptop and I'm considering returning it for a refund.

Lenovo G50 BIOS in this system is not fully ACPI compliant

Hello everybody !
I kinda have a problem as the title states.My neighbour has a Lenovo G50 she bought and came with windows 8.1 x64 ( which she doesn't like at all and in my opinion win7 is far more superior ). The thing is I wanted to install her the Windows 7 Ultimate but everytime the " loading files " ends right after it boots from the dvd I get a bsod with the message " The BIOS in this system is not fully ACPI compliant Stop 0x000000A5 "
I tried all kind of different settings through the bios, changed from UEFI boot to Legacy / disabled secure boot / fast boot / I set the ACHI to compatible / but the end result is almost the same ( two times with different settings my screen froze with a red line over the top after loading the files )
My question is what is the problem and is there a fix for it? (of course it is,but I don't know it )
Thanks !

Lenovo G50-30 Can't adjust the brightness

HI
recently i bought a lenovo G50-30 laptop with windows 8.1(64-bit)
the performance was low and i downgraded it to windows 7 professional (32-bit) which improved the performance drastically,
Now when ever i try to install the vga driver i get this message saying "this computer does not have the minimum requirements for installing
this software",and also i cant adjust the brightness
Did i do anything wrong,does anyone know what to do
please
Thanks

sorry for the late reply, here's the things you can try , try rolling back the driver or you can access the registry to adjust some values here's the step:
1- install latest driver of your graphic card
2- This step will fix the problem:
3 go to registery by regedit and change the value to 0xf048
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"FeatureTestControl"=dword:0000f048
OR
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]

Lenovo G50 NOT plugged in, but 'charging'.

I just bought a new Lenovo G50 about a month ago. The only strange problem I have picked up in the last 2 weeks, is that even when my notebook is NOT plugged into the charger, it still indicates that it is charging from an incompatible power source. Where my previous notebook, warned me on 10% battery left, my new Lenovo does not, because it is under the impression that it is 'Charging'.
The battery life is not really affected and when plugged in, it charges the battery normally.
Can anyone help me with a solution, before I take it back to my supplier. I know simple fixes like this can take up to WEEKS if I have to take it in.
Thank you in advanced.

hi dentonbronkhors,
Welcome to Lenovo Community Forums!
Can you try these steps:
Open Device Manager and look Under Batteries, Right click and uninstall the item Named Microsoft SCPI compliant control method battery.
Shut the computer down instead of doing a restart like the computer ask.
Now Remove the Battery and Unplug the Ac adapter, Hold the poer button down for at least 10 sec.
Turn the computer back on and See if that resolves the issue.
Let us know your findings
