WIFI not showing up

Hi
I was having an issue with my WIFI, so uninstalled some adapter from device manager under network adapters after which my WIFI didn't even show up. I tried running all drivers for WIFI for DM4-3050us but WIFI didn't show up. Can you help me please?

Hi @sundar_jp
Welcome to the HP Support Forums!
I understand that you are having trouble with your wifi not showing up. Assuming that it was working previously, a good first step would be to try a system restore to a point from when the wireless was still working.
Using Microsoft System Restore (Windows 7)
Other than that you can try these:
Resolving Universal WLAN, Wireless, and Wi-Fi Errors
Assuming that resolves the driver issue in device manager you should be good to go. If it does not, then I would recommend that you call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

If on the other hand you resolve the driver problem but you are still having trouble connecting, then work through these steps and see if it helps.
Troubleshooting Your Wireless Network and Internet Connection (Windows 7)
Also, you can look at the power management for your wireless adapter:
Disable the Power Off option for the adapter:
1. Open Device Manager. (Win Key+R > type devmgmt.msc > OK)
2. Expand the Network adapters.
3. Right click on the Ethernet/Wireless Adapter and click Properties.
4. Click the Power Management tab.
5. Remove the check mark beside Allow the computer to turn off this device to save power.
6. Click OK.
7. Test.
Forget the network: (Windows 7)
1. Press Start.
2. Type Manage wireless networks and click the application at the top of the start menu.
3. Right click on the network and click Remove network.
4. Confirm the warning by click OK.
Reset the TCP/IP settings on your PC:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh int ip reset resetlog.txt" without quotes, and press enter.
4. Restart your PC and test.
It may also help to reset the winsock catalogue:
1. Go to your start screen/menu and type CMD.
2. Right click on the command prompt icon and chose Run as administrator.
3. In the window that opens type "netsh winsock reset" without quotes, and press enter.
4. Restart your PC and test.
Reinstall the network adapter drivers:
1. Download the drivers from here but do not run them yet.
2. Go to your start screen/menu and type Device Manager.
3. Expand Network adapters.
4. Right click on the wireless adapter and choose Uninstall.
5. Run the downloaded drivers from step 1.
6. Restart your PC and test.
Test an ethernet connection:
Self explanatory. Test if the issue persists on a wired connection to rule out the wireless adapter hardware so troubleshooting can be directed towards the right areas.
Test another connection:
Many people rule out their home network as an issue if another device is working on the same network. Networking is not that simple. Each device interacts differently with your router or modem and it is impossible to rule out settings in that device until the notebook has been tested on another network.

Fresh install ArchLinux WiFi not showing (icon)

Don't know whether this is a specific ArchLinux or Cinnamon issue but I'm new to Arch and decided to install (step- by step):
- ArchLinux
- SLiM
- CInnamon
Everything is working correctly, I'm a really happy man now, except for a few little thing(s)
When I boot my laptop I don't see the WiFi-icon like I was used to on Cinnarch/ArchBang etc. When I plugin the ethernet cable I do have internet, and also when I do: #sudo wifi-menu I can select my connection (WiFi) and enter my WPA(2)-key > works. Thought it must be something that I forgot to install (and checked the Wiki) but as far as I can see I did it correctly (network-manager, network-manager-applet, cdr). I even (re?)added my user account to the group network/audio (because my volume button will not stick either).

I don't quite understand what is going on here. You say that you don't have an "icon" in the first post, but then in the third post you say that you can see that network manager is active because it is green. What is green?
Also, in the first post you seem to partially indicate that you are using network manager, and partially that you are using netctl. There two things will conflict with each other of you are trying to use both. You can only use one thing at a time. So if you previously enabled something like [email protected] and then started using wifi-menu, and then set up NetworkManager.service, and didn't disable/stop the others as you go along, you are undoubtedly going to run into issues.

Thinkpad x201 Wifi Not Showing Up under Fn+F5 Windows 7 BIOS 1.22 (Solution)

If you should boot into Windows 7 and find the Wifi adapter off and if you hit Fn+F5 and only the Bluetooth Radio shows up. If the problem persists even after rebooting. The problem being only the Bluetooth Radio shows up. Then, power on the Bluetooth Radio close the window and hit Fn+F5 to open it again and both Radios should show up.
Hope this helps.

I have the non-Intel Wifi Adapter.

Wifi not showing on bar or network interface

I have just reinstalled Snow Leopard on my mac after a HD failure, now Airport does no longer exist anywhere. Please help as I need to travel within 36 hours

I suggest that you try to repair the phone software using PC Companion..
Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.

I have a mid-2010 iMac and just purchased a 2TB TC, can't join existing wireless network with AC standard so attached to iMac via ethernet with TC wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. working fine with TM

I have a mid-2010 iMac and just purchased a 2TB TC, I just found out that it can't join existing wireless network with new AC standard so attached to iMac via ethernet with TC's wifi turned off. How do i access TC now? not showing up in disk utility or on desktop. It is working fine with TM. My cheeper seagate drives etc kept crashing, so i didnt trust cheeper back up options anymore. Connected those drives to TM via firewire and could see the drives and access them.
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc. I connect to the internet via airport only and it is pretty fast. Getting over 50mbs downloads and over 30mbs uploads. Plus everything in my home it connected to my fios router, airport express for music streaming, two apple tvs, vuezone camer system. I really didn't want to monkey around too much with my system. But are there other options to connect the new TC. Can't find info anywhere for this and called apple who gave me the info above. after hanging up, i see that i cant access my TC and I am wondering if i would have to reset it to turn wifi on again to make changes to the drive, turn off blinking light or repair it in disk utility if it should become corrupted.
For other with similar issues i did solve some other problems: when i connected it to my ethernet port on my iMac wifi stopped working. Found that I had to turn off the ethernet in the system>network screen, but then TM didn't see the TC so i restarted after changes and then it saw it.
Now a rant. I can't believe in this wireless age that Apple would make a product that cant join a wireless net work. The apple rep said i could return it and look for the previous TC that would join an existing wireless network. Are we going backwards?
Thanks!

Ok... it is getting a bit clearer but there are still some questions.
I connect to the internet via airport only and it is pretty fast.
I was assuming airport in this statement in your first post meant the TC or the Express.. but I now realise we are still in the mass confusion stage where apple calls everything wireless an airport. So what you mean is the airport internal card of the computer??
Also, I didn't want to bridge TC with my new fios router that I paid 100 dollars for, to get N speed and also paying 10 dollars more a month for fast speed. I heard that bridging slows down everything and then there can be port issues with mail etc.
I think this is mistaken.
Putting the TC in bridge mode plugged into your FIOS will not slow the network.. nor will it cause mail or port issues.. in bridge the TC is just a fancy WAP and switch plus the network hard drive.
If the computer is close it will be faster than the FIOS.
You can run both wireless networks with different names.. so it is clear which is which. But you can also setup roaming so the computers themselves pick which is the best wireless.
I tried extending the wireless net work and tried joining wireless network, but the TC kept crashing and I had to keep resetting the TC. the Apple support person said these, extend wireless network and joint wireless network, are no longer a connection option with the new TC because of the new AC protocol.
Thanks again!
You cannot extend to a non-apple wireless router.
You cannot use join a wireless network because when you do the ethernet ports will be cut off.
But that has not changed.. I don't think Apple support is correct.. there has been no change with the AC model.. it is simply a fact that apple routers do not work in join wireless mode other than as a dumb client. The same applies to AC as to the earlier version.. but I have asked another person to check this.
Join in the express is the only apple router that still allows an ethernet connection.
For now you best use of the TC is bridged to the FIOS. Wireless you can sort out between several options.

My iPad 4 does not show up on my TV screen when in AirPlay mirroring mode using WiFi. The iPad displays AirPlay set to TV with the Mirroring On (green).
My iPad IOS software is 8.2 and my Apple TV software is at 7.1. The TV displays the Apple Menu. The “Settings” does however displays the General menu allowing me to see:
Apple software: 7.1 (7003)
Apple TV: Model No. A1464, Part No. MD199B/A
Signal Strength shows 5 circles.
It does not display the iPad screen but when I use the BT Sport App I can hear the sound but there is no video. I have searched the internet for a solution to no avail. The problem first arose when the IOS was at 8.1+ but it worked correctly briefly when I updated to IOS 8.2. Can you help please?

Welcome to the Apple Community.
Try the following steps, check whether things are working after each step where appropriate, before trying the next.
Check AirPlay is turned on on the Apple TV (turn it off and on if it already is)
Check that both devices are on the same network (Settings > Wifi, on the mobile device and Settings > General > Network, on the Apple TV).
Restart the Apple TV (Settings > General > Restart).
Restart the Apple TV by removing ALL the cables for 30 seconds.
Restart your router. (Also try removing it’s power cord for at least 30 seconds)
Restart your mobile device.

My wife purchased some songs from itunes for her iphone. If I go to sync her ipphone with our itunes library will her purchases be wiped out. They do not show up in our library on my computer.

My wife purchased some songs for her new iphone from itunes on the phone. They do not show up in our library on my home computer. When I go to add new songs to her iphone from my computer are her purchases going to be wiped out.

Is the computer authorized for her iTunes account? If not, sign her in in iTunes and then go up to: Store>Authorize this computer. You say "our library", does that mean she does not have her own computer login? Has she ever synced to this computer/iTunes before? Once she is logged in & the computer authorized for her account, you can transfer purchases on her phone without syncing. With her phone connected, iTunes running: File>Transfer Purchases.

I used my ipad to transfer music to my wife's pc, now I have reconnected to my mac and itunes is not recognsing it - the ipad is not showing in the sidebar and syncing not happening. I have tried resetting ipad and restarting etc but still no joy. Anyone had a similar experience?

Take it to the Apple Store for evaluation.
Try this.
Restart the iPad by holding down on the Sleep button until the red slider appears and then slide to shut Off. To power up hold the Sleep button until the Apple logo appears and let go of the button.
Reset the iPad by holding down on the Sleep and Home buttons at the same time (for about 10-15 seconds) until the Apple logo appears (ignore the red slider), then let go of the buttons.

Photosmart C310: WiFi connected, but not showing up in network via Mac or iPhone

I am using a HP Photosmart Premium C310. It is connected to WiFi, but does not show up on Mac or iPhone via Wifi:
- iPhone Airprint does not find the printer (select printer)
- Mac "add printer" does not find the printer
- newest HP Setup Application (HP_Lion_Ink_SW_v12.13.14, Dec 2011) finds printer only as long as connected via USB, reconfigures WiFi settings, but can not re-find the printer when USB cable is taken off
- I can send "ping" to the printer using the IP address shown in touchscreen info panel so it is online in WiFi
- I tried to reset factory settings for settings + network settings, no change...
Is that a defect or any idea how to fix the problem?
Best regards, any help appreciated...

Hi,
Per your description, i believe the issue may being caused by your router compatibility with Apple Bonjour, which require multicasting support in order to operate propertly.
In order to verify, try to temporary create an ad hoc connection between your iPhone and the printer and check for any change:
Step One : Restore the network defaults on the HP All-in-One
On the product control panel, touch the Setup icon ( ). The Setup menu displays.
Touch Wireless .
Touch and then slide your finger down on the display to select Restore Network Defaults .
When asked 'Are you sure? ' touch Yes .
After the network defaults restore, touch Wireless Connection , and then touch On .
The message 'Wireless Radio is now on ' should briefly display on the control panel and the Wireless light ( ) on the HP product should start to blink. The HP product is now openly broadcasting the ad hoc wireless network.
Step Two: Create an ad hoc wireless network connection between the HP All-in-One and the Apple device
On your Apple device, tap the Settings icon ( ).
Tap Wi-Fi .
Under Choose a network , find the name that starts with HPC310 , and then tap it. A checkmark should display to the left of the name.
Wait three minutes to make sure that the ad hoc connection is established and try printing from the iPhone by taping the Action icon ( ) and then tapping Print.
If you were able to print through the direct printer, it means the router more likely cause the problems..
Please clarify your router brand, model and the router firmware version if available.
Regards,
Shlomi

Broadcom wifi chipset not showing adapter

I have a BCM4313 which is using the brcmsmac module, but iwconfig, ip addr, and 'ls /sys/class/net/' do not show my wifi adapter.
For the record, in any other distro that has more automation my wifi card works right out of the box.
I was able to setup a wifi connection in the network-manager, but I can't use it.
[root@moniker ~]# ls /sys/class/net/
eth0 lo
I tried to rmmod and modprobe the module as some articles suggested, but that didn't do anything either.
Any help would be appreciated.

Gusar wrote:Did you blacklist the bcma module? The wiki says "The bcma module can prevent some cards from showing up and may need to be blacklisted" but there is no "can" and "may", bcma and brcmsmac are for sure in conflict, so you need to blacklist bcma.
Yeah, I guess a reboot is all I needed after doing all that. Thanks.
