Network / Sharing :: Lenovo 3000 G430 - WiFi Is Not Detected After Windows 8 Install?
Oct 24, 2013
I installed Windows 8 in my notebook, Lenovo 3000 G430. It worked fine for a while, but after I had a long shutdown, when reboot again, the Wifi was not working. The drivers are still there, and when activating the Wifi from Fn F5, it goes to Airplane Mode.
I removed Windows 8 and reinstalled Window Vista, the Wifi came back and working fine. I tried this many round, it produced the same result.
I believe that it is compatible issue with the driver for the Wifi. Can some one able to provide the driver for BROADCOM Wireless 802.11g for Windows 8?

I have a cisco e4200 and after installing Windows 8 RP, I was unable to find the 5GHz band. I am getting 90Mbs on the 2.4 GHz band and I know my 5Ghz band can give me more. The 5 GHz band is detected on my PC before Windows 8 was installed but I can't find it on my PC now. I have two computers who support the 5 GHz band and both can't find it but did with Windows 7. The 2.4 GHz band and 5 GHz band are separately named so that isn't the problem.

Lenovo P585. The wifi does not work all that well...... It either switches between 2-4 bars infrequently or it takes 10-20 seconds for a page to start loading. My drivers are up to date.
Recently it has gotten worse and sometimes it says I have no connection all together. My tablet and other computers connect fine enough and don't have the same 10-20 delay for a page to load.
Also a torrent site I go to frequently has not been loadable for over a month. The torrents also don't seed. The site will only load on my Windows Phone 8 with wifi on and 4g off. This lead me to believe that my ISP is not blocking the site.
I get this on any PCs in the house: Error code: ERR_NETWORK_ACCESS_DENIED
Not sure why this happens, every other page loads fine.

When I installed the Video card, I either disabled, or uninstalled, the Intel HD 3000 Video adapter. I am now having issues with the card and wanted to try using the Intel graphics, before replacing the card, but they are no where to be found. "Scan for hardware changes" produces nothing.
They do not show up under display adapters in Device Manager, so I can't enable/install them. I d/l the last 2 versions of drivers form Intel, neither will install -

The cable works on a different computer, the computer gets wireless fine (typing to you from it) but will not read an ethernet cable. The motherboard manual (built the PC myself from components) says an LED should light-up if an ethernet cable is connected, no such LED appears when I connect the cable.

I'm not truly the best with computers, and this is a new pop up for me. I just purchased this new dell laptop in May and have had no problems with it. However, in the last few weeks I've been getting a new pop up in the right hand corner. My house hold have a wireless router that is password protected. I have McAfee Security Center updated, and shows that all my firewalls and security systems are on and active.
However, this is the message I get and I'm concerned about my networks safety:
"Unknown PC or device detected
This PC or device has connected to your network:
IP Adress xxxxxxx"
I've opened my action center to make sure everything is okay, and the only thing I find that isn't turned on is the "Network Access Protection" - which is something I haven't touched before, nor does it provide a link in which to turn it on.

I have a lenovo G505 laptop - it will no longer connect to my BT home hub despite it showing as being available. I suspect it might be to do with the fact that it is has a passkey - I entered it yesterday when prompted and it connected fine, but now I'm not being given the option of entering the key.
I've also tried connected using the BT wifi (as opposed to homehub) but once again it will not connect me. I've been through all the troubleshooting options, and searched under every term I can think of, but nothing is working.

Is there a way to setup network profiles or something so that when I bring my Surface Pro to work and connect to the wireless network there it will use the static ip address I have but when I disconnect and then connect to my home wifi it will go back to DHCP? On my MacBook Pro I can go into the network settings and change the location profile I have setup for networks but I don't see anything like this for Windows 8.

I'm having trouble keeping my lenovo laptop (running windows 8) connected to the internet. I have been able to connect successfully to multiple wireless networks and access the internet until I tried to connect to the new network.
Initially everything is OK - I can connect to the network and access the internet. However after a short period of time (anywhere from a few seconds to 20 minutes) the network connection will change to limited, without internet access. If I simply disconnect and reconnect to the network the internet will immediately be working again (at least for a few seconds/minutes).
Alternatively, if I run the troubleshooter, I always get the message that the default gateway is not available, which has been fixed by resetting the wi-fi adapter.

I just got a new Windows 8 laptop, a Lenovo Y510p, and I've been having several wireless issues with it. Pretty early on my computer froze up so I had to force it to shut down. After resolving the issue, I was unable to load any websites, however a flush of the dns cache fixed the problem right up. Fast forward a few hours, and suddenly I can't connect to the router in my dorm room-I just suddenly lost my connection and now I can't reconnect.
My roommate has a router set up for our room connected to an internet jack in the wall. It is configured as WPA2-PSK. I usually connect to this when in the room, but now I can't-windows just says "can't connect to this network". There is wifi throughout the dorm already, which I can connect to just fine, however the signal isn't as strong.
This is a link to my ipconfig : ipconfig - Pastebin.com

I purchased a new Windows 8, Inspiron 15 7000 series - 7537 last December. I had been using a router at a hotel for the time, and it worked correctly. When I arrived home, I had a Belkin router, and i experienced network issues in that i could not connect to the wifi. I could connect with Ethernet cable. The problem was fixed through customer support eventually, but I now have a new Comcast router, and i'm experiencing what appears to be the same or a similar issue. I can access the internet fine by wire. With wifi, it says i have access to the internet over the internet icon in the bottom right, but i cannot access webpages. I can use skype, and communicate through it.
Here is the result from the ipconfig /all :
Microsoft Windows [Version 6.2.9200]
(c) 2012 Microsoft Corporation. All rights reserved.
C:Windowssystem32>ipconfig /all
Windows IP Configuration
[Code] .....
I really need the wifi on this router working for this laptop. Let me note that it works on other laptops, so it should be an issue with hardware or settings on this laptop.

I have two wifi APs in the home and only one has an Internet connection. the other is to access the wired LAN.
Last week I updated from Windows 8 to Windows 8.1 and thought everything was going well until I started getting wired LAN dropouts.
I have traced it back to 8.1 handling connection to wifi APs. In Windows 8, I was able to have "Connect automatically" for BOTH wifi adapters on this laptop. Now when I try to connect to the non-Internet AP, Windows 8.1 announces (correctly) "Limited access" and that's what Windows 8 did too. BUT, Windows 8.1 waits a few seconds then drops the connection with a useless message, "how me solve connection problems," where there is NO problem. A limited connection for the AP to the wired LAN is OK as it was in 8.
So now I am stuck with no home LAN access unless I drop the Internet AP and connect to the LAN AP.
Also, in the great wisdom of 8.1, because it is only a "limited" connection, it does not remember the Passphrase so I have to type it in every time. So much for progress.
What to do to get past this behavior and have a "limited" connection as OK as it is with Windows 8?

I prefer to keep my home WiFi network from public view by disabling the SSID broadcast, i.e "hiding" the network.
With two modem/routers (a Belkin Play Max F7D4401 ADSL modem/router and now a Cisco EPC2325 DOCSIS modem/router) on two computers (home-built desktop and Acer TM8172T notebook), after the initial connection Windows 8 Pro would not reconnect without tediously re-entering the SSID name and password. Once it does connect, it displays the original SSID name with a new one with an incrementally increasing appended number like:
I was manually deleting them all (except the original) using netsh, until I realized you can <right-click> on an entry in the screen above and choose "Forget this network."
This is the process I go through each time to re-connect. Is there something I'm missing?
I read that if Windows 8 saves too many WiFi connections, it cannot "remember" them to automatically reconnect to them, so on the notebook, I deleted all but wpcTrue (the original), and it now automatically reconnects, although occasionally it will add a new connection with an incrementally increased number -- currently the notebook shows both wpcTrue and wpcTrue 2. I had used the notebook on the road, so had about five WiFi connections saved. On the Desktop my home network is the only WiFi connection I've ever made. However, no matter what I do on the desktop, it NEVER remembers to automatically log on when the SSID is not broadcast.
I even tried manually setting up a connection via Network and Sharing Center > Set up a new connection or network, to no avail -- the desktop computer will not automatically reconnect.
I doubt that this is relevant, but the Belkin modem/router, the Belkin USB adapter I use on my desktop computer, and the notebook's Broadcom internal modem are all b/g/n. The Cisco modem/router is b/g.
If I "unhide" the SSID, i.e. broadcast the SSID, all is well in the world. Both computers automatically reconnect to the modem/router. If I hide the SSID, and then disconnect or reboot, the desktop computer will not automatically reconnect.
I just noticed that the pop up WiFi connection column shows "WiFi-2 Off" -- what does the "Off" mean?
And, why is it "-2" ? My notebook just shows "WiFi', period. (The first image with "WiFi (Off)" was from a previous Windows 8 installation on the desktop computer. I decided to change from EFI-boot to non-EFI so reinstalled Windows 8. I simply used the old image as a quick way to show how the connection name assignment runs away.)

My ISP provides service only via 802.11. I use laptop A most of the time. The captive portal for the service provider only allows one login per account at a time. The policy is intended to prevent multiple people sharing one account. It's just me, I'm the only user, but very occasionally I'd like to have a 2nd laptop access the internet simultaneously. No abuse, just the simple convenience of not having to logout from A if I need to use B for 30 seconds.
What I want to set up seems simple and it probably is:
WiFi Internet <---> Laptop A <---> ethernet cable <---> Laptop B
Such that Laptop B can share A's active WiFi connection without having to request its own unique address from the ISP.
At present, Laptop A has its network interfaces set up so:
- WiFi is connected, active, functional. Selected the "Yes turn on sharing and connect to devices" in sidebar.
- Under the wired network properties IP Version 4, I manually set addresses to be
IP 192.168.10.1
Subnet 255.255.255.0
Gateway 0.0.0.0
Laptop B has only a wired network, set to
IP 192.168.10.2
Subnet 255.255.255.0
Gateway 192.168.10.1
A & B can connect directly to each other, share folders, etc.
What do I need to do in order to get laptop B to transparently use A's WiFi connection? My guess is that A needs to be set up to do some routing between the internet side and the 192.168.10 subnet, and B needs to be set up to look to A as its "ISP" ... but I don't know where to begin.

My laptop is few months old HP Pavilion g6 OS: Windows 8 uses a ralink rt5390r 802.11bgn wifi adapter.
The wifi was working just fine suddenly it stopped. It detects my home network but every time it tries to connect ends up "unable to connect to this network". It connects to my friends wifi but not mine. And it connects with cable.
There is a red cross on the wifi network but it's green not GREY. It is not a modem problem because the other PC connects just fine. When I'm on wifi, cmd ipconfig gives me disconnected media for all the network cards on the laptop. Command netsh shows failure and access denied.
What I have tried to do for the past week :
I upgraded the adapter/ driver. My windows is fully updated. I re-installed the network card. I tried a USB wifi. I uninstalled the private server. I uninstalled my Norton because I thought it was blocking the connection I also deactivated the windows fire wall. I changed the SSID and PSW ... nothing worked. and of course I tried restarting, resetting, rebooting, deactivating and activating, disabling and enabling every single thing but nothing works.

Since upgrading my HP DV6T7000-CTO from Windows 7 to Win 8 and now 8.1I have had an intermittent issue where the my wifi/bluetooth adapter is detected, until a restart, and then afterwards, is no longer detected. I have a Intel centrino wireless N 2230 which is both wifi and bluetooth. I cannot connect to wifi, nor is the bluetooth detected. Additionally, the wifi-radio button on my laptop, will not turn on (red is off, white is on). Sometimes I can temporarily fix the issue by shutting down,disconnecting the adapter from my laptop, reseating it, and then rebooting. This does not always work though.
I have tried the latest drivers from Intel as well as tried removing those and just installing whatever Windows update thinks is best. I have also updated the Bios to the latest, but to no avail. I have even replaced the adapter with a new adapter but the same model and that did not fix the issue either.

" The hosted network could not be started
The group or resource is not in the correct state to perform the requested operation"
How can I determine what this means and how is it resolved
I did check using the command prompt that this was possible with the computer and received acknowledgement

I just bought a msi s30 laptop yesterday. So everything went fine when I test the wifi connection before I go to sleep. When I say fine, I mean I could connect to the internet. Then when I woke up this morning, I turn on the wifi but it says "no network found". I check the router and it is working perfectly fine. I also checked the device driver and its also working properly.

My girlfriend recently updated her computer from Windows 8 to 8.1 Since then, she's been unable to connect to her home wi-fi. She can only connect via cable. Unfortunately, neither of us have disks to roll her back to Windows 8.Yesterday she brought her computer to my house and it connected to my wi-fi with no problem.
I updated her adapter drivers to Windows 8.1 but that had no effect on her ability to connect to her home wi-fi network.Last night she ran "troubleshoot problems" and it says that her adapter is damaged. I highly doubt that since the computer is only a couple of months old and she could connect to my wi-fi network.
Computer: Lenovo G405
Modem/Router: ZTE ZXHN F660

Recently upgraded my laptop to Windows 8.1 and I cannot see any 5Ghz wireless networks, even though they are present (I am able to successfully see and connect using other devices including a Windows 7 laptop). I can see 2.4 Ghz networks and connect no problem. I have upgraded the wifi driver to the latest Windows 8.1 version for the Intel Wireless-N 7260 card, v16.6.0.8 but no luck.

For some reason my windows 8 Hp will not connect to my home wifi network. Has had no problem connecting in the past but yesterday I unplugged my router to move it to another part of my house and ever since then it can't connect. My cell phone and other laptop connect to the internet no problem.
On my Hp it will show a list of wifi networks and my home network is on the list, however, when I try to connect to it and then troubleshoot the problem it says I can't connect to the network because it is hidden. I don't see how thats possible since the network name shows up on the list of nearby wifi networks.
What I've done but hasn't worked:
Reset my router and laptop multiple times.
Tried to manually connect to network.
Forgot the network on my laptop and tried to reconnect.
I don't understand how one day it can connect to the wifi fine and then I unplug it and all of a sudden it can't connect but my other devices can.

Windows 8.1, Broadcom 802.11n network card&driver,
My computer stopped recognizing the wireless networks at my university - oddly enough, some other networks elsewhere can be found (although I cannot test if I can actually connect to them, since they are passworded/not mine).
I followed the 3 steps of Network Posting Tips
Xirrus Wi-Fi Inspector showed nothing: Connection - Broadcom 802.11n network card - NA, everything under Wireless and Addresses also NA. No networks.
My home adsl modem works.
