Lenovo B / G Series :: G570 Network Adapter Not Found (for WiFi And Bluetooth)
Jun 6, 2013
My lenovo g570 laptop does not found network adapter for wifi and blue tooth it did not recognize the hardware part may be. because i install software for that so may time. few days back i used wifi as well as bluetooth in my lapi but for last two or three month i just used lan for internet connection and in between i changed my os which is win 7 ultimate to win 7 proff. I don't know what is the reason for that.
I think when I set up this computer I selected that it always maintain the wifi connection. Normally this is fine, but if I am installing a program I may not want the computer to connect to the internet.
I recently clicked on the wifi icon in systray and right-clicked on my connection and selected "disconnect". It did, but it immediately reconnected. Where is the setting where I can control this?
First my notebook specs Lenovo G570 (part number: 43345JU) i5-2410M 8GB RAM Qualcomm Atheros AR9285 WLAN dont know the make of bluetooth (mostly broadcomm) Came with Win7 Home premium x64
The Win7 that it came with also had lenovo energy management through which I could toggle the WLAN and bluetooth on and off. Since I never used the bluetooth, I turned it off via energy mgmt.
Also interestingly, when I was running Win7 I had it dual boot with Ubuntu. And if my Bluetooth was turned off via EM from win7... bluetooth wouldn't be recognised in ubuntu and there was no way of turning it back on... I had to boot back into win7 and turn it on via EM and boot back into ubuntu.
Recently I updated to Win8.1 but hadn't turned on the bluetooth before doing so. In Win8.1 the bluetooth device is not recognised anywhere..not in PC settings(metro UI), not even in device manager. I tried to install the energy management for 8.1 from the support site but it was extremely buggy and didnt find any option to turn on bluetooth. The old EM didnt install properly in comaptibilty mode.
In ubuntu now (dual boot with win8.1) its still the same. Bluetooth not regonised just as before.
I cannot go back to win7 now. There is no proper EM for win8.1. There is no option in BIOS regarding bluetooth. How do i turn on the bluetooth adapter?
I received my G570, and have had internet issues since. It can connect to my WiFi network, however after using the internet for a few minutes, it consistently gets the yellow "!" over the wifi icon in the task bar and says no internet connection and I loose my connection. I know it is an issue with THIS laptop since my old and decrepit HP laptop which sits next to it works perfectly fine using the same network, as well as my smartphone and room mate's devices.
I have downloaded the Lenovo update software and attempted to use it. I get a message saying something along the lines of no available packages, assuming that means everything is up to date in terms of drivers.
I have done some research with the terms "lenovo, g570, wifi, internet, problems, connection" and yield many pages, however none have seem to provide a solution that works for me.
I am using ideapad y510p. My wifi worked perfectly yesterday evening. However today at morning I couldnt find any wifi networks. After some research I have discovered that there is not wifi adapter present in Network Adapters and also that there is no wifi adapter in device manager. However bluetooth works fine. I have tried reinstalling drivers (even clean install of everything that may have something with networking). But I still cant see any wifi adapter. LAN connection works just fine. I dont think this should be hardware related problem because as far as I know bluetooth and wifi adapters are both located on Intel Centrino N2230. So I think that if my wifi adapter would be broken than bluetooth wouldnt be working too. I have also tried using system restore point to last week (when everything was working perfectly) but it didnt work.
I have also downloaded latest drivers from intel website and when I run tests with theirs WiFi Software Utility (or whatever it is called) it says that there is no wifi adapter present so it fails even hardware test.
I bought my HP 15 a few days ago and since yesterday (after I restarted it) it can't find my network. Also, sometimes it finds all the surrounding networks, sometimes one or two, sometimes none of them, but it never shows mine.
All my other devices connect to the network just fine and also when I connect the laptop via Ethernet cable internet works normally. I tried reinstalling the adapter and driver, but nothing happens, the problem is still here.
i bought a acer laptop @ bestbuy and it came with preinstall vista home. i used the computer fine and all and the internet connects to my router find and was surfing the internet. i then decided to install a fresh copy of my own vista ultimate because i dont like the preinstall stuff that they did because it just clutters up space. after i finish my install of vista ultimate, my laptop doesn't connect to the internet. i know this is simply but i dont see network adapters under the device manager in the computer management screen. i am worried because if i have to install the driver, then i would see some icons with a yellow exclamation mark, but i dont see NETWORK ADAPTERS AT ALL. i dont know how to solve this? any help would be greatly appreciated. thanks all. i've tried to press scan for new hardware changes but still i dont see the network adpaters. i thought if you install vista ultimate, then it will install the wireless drivers for you too.
I have a feeling that I am missing something very obvious here, but I have looked everywhere and cannot find the Bluetooth services on my laptop (W530, Windows 7 Pro 64 bit, ThinkPad 1x1 11b/g/n Wireless LAN PCI Express Half Mini Card Adapter for Windows 7).
When I do FN + F5, I get the Lenovo Wireless Radio menu, but it only lists Airplane Mode (off) and 802.11 Wireless (on).
I have check BIOS security settings for I/O devices and Bluetooth is enabled. However I cannot find any references to Bluetooth under Device Manager ->Network Adaptors.
Is it possible that this laptop is not equiped with Bluetooth?
My new Lenovo Z580 runs windows 8 64bit, core i3 3rd gen, 4gb RAM.
The problem is, since day 1,every few minutes the internet stops working. It shows as connected, the router is working, other connected devices run as intended and everything's fine. But internet doesn't work on my laptop. It says "Could not connect to the network". I have tried doing the "keep wifi on during sleep" etc. but nothing works. It just stops working after a while even though I am using the laptop, it just suddenly stops. It even shows as connected, and packets are being received but internet or any application over the internet will not work untill I disconnect and reconnect.
I have an Presario CQ57-383SQ and in device manager, network controller has no driver and i can`t find it and my WI-FI doesn't work it shows that is disabled from device manager i thins it is because of the network controller driver.
And one more....PCI device has no driver and I don't know where to find it.
I had to reisntall the factory default software to original. The problem is the Wifi and bluetooth drivers do not install. I tried installing several versions from the lenovo download site but i either get "No Matched Wireless or nothing depending on which one I try to install.
The Laptop is a Lenovo B570, Model Name 1068. Running Windows 7 64 bit.
I bought a U410 knowing it didn't have bluetooth, at the time I thought I wouldn't need it. But now I would like to have it. Is it possible to upgrade the Centrino Wireless-N 2200 card, to a card that includes bluetooth?
My Lenovo G570. Yesterday, it was working perfectly, I properly shut is down. I have set a BIOS pasword. Today, when I switch it on, I was unable to type the pasword becasu some keys were not working. However, I managed to loged in with On Screen Keyboard. After analysing it, I came to know that some keys on numpad includeing 0,2 and on the 2nd line(vertical numerical keys) 1,2,3,4,7,8,9,0 are not working. I tried to re-install the OS but I set a BIOS password containing one of the missing keys.
I have a 3444-CUU that I really love. When I first got it I realised the wireless adapter would just randomly stop working. I updated every possible driver and I'm still having the same issues. All I can do is reset the adapter to get it kicking again. I'm not sure if the wifi care is soldered or if it could be removed or replaced but I'm really leaning towards it being a hardware issue.
It'll either stop working could turkey, won't detect any wireless networks or it'll stop working and I can still view other wireless networks but I cannot connect to them. Resetting the adapter is the only option. As I'm writing this right now the wireless has gone out again. So I have to reset the adapter for 5-10 more minutes of internet just so that I can post this.
I've looked at the other threads and tried removing the battery while the laptop is off for 30-40 seconds but it doesn't run because it's not getting power from the charger at all.
The laptop is a couple years old and the hinges on both sides have been pried off (can provide pics) but I never had problems until now - I plug the charger in but it won't charge and even if I pop the battery out it STILL doesn't charge!
One night, I had to set the charger upright in order for it to charge. Today I had to set the bulky and heavy part of the charger higher above the laptop in order for it to charge. Now, how to get this thing to work because proping the charger upright or higher than the laptop isn't working anymore!
I've noticed a couple weeks ago when I was visiting my parents that the adapter emits a beeping sound - notice that I said the adapter NOT the laptop. If I unplug it the beeping sound fades. The beeping sound comes from the adapter and when I unplug the cord going from my laptop to the adapter you can hear the beeping sound fade away from the prongs that conect the adapter to the laptop (not the prongs that plug into the outlet).
Like I said before it doesn't matter if I've plugged it into an outlet with OR without the battery in it, the laptop does not receive any power from the adapter or recharges.
My Lenovo G570 battery is stuck at 90%. It says plugged in, not charging. It just happened over night. Next day battery refuse to work.
In windows it says battery 90% and is not charging but battery has no charge at all. When I disconnet the A/C power laptop just shutdown immediately. As soon as I unplug the power laptop just shutdown as there is no charge in the battery.
I did reinstalled the Power management and also updated it. I all unplugged reboot in OS, restart, put battery back and boot into the OS back. Nothing seems to work.
I just installed Lenovo Energy Management in windows 8 before I was trying in windows 7. In the battery tab there are two options
Maximum battery Life Optimized battery Health. It is selected to "Optimized battery Health" and won't change regardless of power plan. I click on "Maximum battery Life" and when I open the app again it reset it to "Optimized battery Health".
Lenovo Solution Center say that battery life is GOOD. "Your battery is in good condition".
i have encounter a new problelm with my laptop(G570) that it does not intall my new printer driver which is hp deskjet 1510. it says that drivers does not exist for the machine. i dont understand what should i do , when the same printer i install in my desktop home pc its get intall. even i take technical assistance from the hp. they check and say that this the problem is with ur laptop.they say that ur laptop machine is not allowing the printer to intall driver. i dont understand what should do in this situation i tried so many(install and uninstall) times but same problem prisist.
I manage to pair my 2-in-1 pc Acer Switch 10 with an externat Bluetooth (bt) device only when the tablet is connected to my home wifi network. As soon as I disconnect from the wifi network, the pairing with the bt device is disabled. If I try to pair the bt device when wifi connection is off, the pairing succeeds just for a few seconds (1 or 2) and then it disconnects.
The support assistance of the bt device, since it actually manages to pair with the pc in such wifi wird conditions, suggested that it probably can be a problem due to the chip of the pc that probably manages both the wifi and the bt connections and is not able to manage them separately.
and updating the bt driver downloaded from the ACER Drivers and Manuals webpage. However, the installation procedure were interrupted as the installed bt driver appears to be "later".
My SL510 work fine, but just want to know, when I open it for replace the keyboard, I found 1 intel centino mini wifi card N1000 with antenna and at the back an other one is broadcom mini wifi card 802.11g without antenna. My question is: for what function is broadcom mini wifi card 802.11g without antenna? All of 2 are presents as well in device manager...
I am trying to connect my E520 to a wireless router. The router isn't connected to a modem, it will just be used so I can transfer files between two wireless devices. The wifi router is functioning properly as I can cannect to it with the wifi on my phone. However my laptop doesn't even see any wifi networks to connect to. The wirless "radio" button (F9) is on.
- There us is no visible wifi network.
- I can connect and access the router and its settings using the ethernet cable.
- 1st method - When I go to "Network and Sharing Center" I select "Setup a new connection or network". From the box that appears I select "Setup a new connection". The next box asks me to choose a wireless router from the list and informs me it may take up to 90sec for a router to show up. However no routers show up at all even after 30min.
-2nd method - I go to "Network and Sharing Center" I select "Setup a new connection or network". From the box that appears I this time select "Manually connect to a wireless network". Thsi time I get a box with an error "An unexpected error occured". It doesn't give any more information than this and I have looked in the logs and though I don't know what I am looking for nothing jumps out.
-3rd method - I go to "Manage wireless networks" and click on the "add" button. The box that appears asks me to choose between "Manually create a network profile" or "create an ad hoc network". Choosing either of these reslts in the same "unexpected error" with no information.
Things I have tried:
- Uninstalled the wireless card drivers and installed the latest ones. (device manager says device is working properly). - let windows try and update the driver. - Turned off my firewall and internet security and tried again. - Disabled power management for the wireless card. - Physically checked the card in the base of the laptop - all seems ok.
Win7 64bit Home Premium Zonelalarm Extreme D-link DIR_600 wifi router.
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 18.104.22.168, 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 have problem with wifi connection. Wifi works perfect with other devices: phones, tablets, laptops. When I connect to wifi with L440, wifi works 5-30 min. and then crash. L440 kills wifi network. All devices can't connect to wifi until I restart router.
I have read about this problem, but in task manager I can't find "discovery.exe" or LenovoEMC Storage Connector in Contral Panel.
I have a problem with my L530 and the WiFi Connection. When I start the computer and see the Login-Screen of Windows 8.1 the networkicon left to the betteryicon have a red cross. After I log into Windows 8.1, I have no wireless connection availible. In the devicemanager is no wirelesscard listet, also there are no other problems with other devices.
After restarting, power off/on, removing the battery and so on about 1.000.000 times the wireless card is pretty working to the next shut down. So my workaround was to use the standby mode instead shut down after I've finished working.
UNTIL yesterday! Now I can't enable the wireless card... This card is installled: ThinkPad Wireless LAN (11bgn, bg)
I've tried the following things: - UEFI is on version 2.56 - loading UEFI defaults, save and reboot - remove the battery and power plug -> push the power button for 10 sec - disable hybrid shut down in windows - booting with ubuntu 13.04 -> no wireless hardware available... Nothings works...
