Turned Off Power Save and Network Adapter Continues to Shut Off Hp

WiFi instantly turns off

Posted by RichardV et al.

Hello Spiceheads,

I am working on a HP EliteBook 850 G2 Notebook PC with Windows 10 on it. up-to-date.

The issue I am seeing is that the WiFi turns off within 5 seconds after turning it on. It sees wireless networks and just turns off, no exclamation mark or what so-ever. One detail: The laptop has been stationary for a long time and been using a wired connection. No one can tell me how long this has been running this way and why.

The following steps have been attempted:

I have disabled and re-enabled the adapter
Updated the driver with Windows update latest driver
Removed/Uninstalled the device completely and reinstalled (with reboot)
Updated chipset and WLAN drivers loaded from HP (see https://support.hp.com/ca-en/drivers/selfservice/hp-elitebook-850-g2-notebook-pc/7343211 ) (with reboot)
Checked power options and disabled control of the device
Reset network (with reboot)
Update 1903 cannot be removed as it does not show in the windows update list. (https://www.askwoody.com/2019/yet-another-bug-in-win10-1903-upgrade-may-knock-out-certain-wifi-cards... )
Checked the logs but nothing stands out (maybe need a more particular log to look at, but not sure where that would be)
Uninstalled update 1909.

After all this, the issue is not resolved. Please advise.

In BIOS, there is a setting to enable LAN/WLAN switching which automatically disables the wireless card when an ethernet cable is connected and visa versa. You may be having this issue.

It's probably a bad wireless card. Replace it. They're like $20 on amazon or ebay.

I have used both of these solutions on HP laptops. Since you already did the BIOS and Chip set updates the only other thing I would suggest is if this is plugged into a docking station/port replicator this could also have some play here. Even if the docking station is an HP. Unplug the docking station and try updating again. Sounds crazy but four of us at the last place I worked chased crazy HP docking stations around for a couple of years. Every time there was an update the docking station would lose its mind. That could be a whole column here on its own.

Good luck

Didn't know that this device came still with legacy BIOS. Thought it would have been turned to more modern UEFI system firmware instead. Don't have EliteBooks but ProBooks instead which don't have such a configuration option in their firmware.

I've the similar behaviour which I configured long ago. It was one of the HP tools which provides such a policy option. Don't remember, if it was a component of HP Sure Run or Click or a separate tool. Still works as expected with Windows 10 1909. If it is this HP tool, then it should automatically disable WLAN as soon as ethernet is working. If you've configured WLAN to be enabled automatically in Windows, then removing ethernet cable should activate WLAN and the automatic Windows configuration should then establish WLAN connection. My Windows driver list reports candidate tools like HP LAN/WLAN/WWAN Switching and Hotkey Service and HP Wireless Button Driver. Have a look if those are installed on your EliteBook and how they're configured.

So do you observe your reported behaviour regardless if ethernet is attached or only if ethernet has not been attached?

Did you ask a search engine to look into HP forum and into this Spiceworks forum? Should give you some hints like this topic (How to disable LAN/WLAN switching Windows 10 HP) a few months ago here in this community.

This wouldn't be an Intel Centrino wireless NIC would it? I recently upgraded a 650 G1 and Windows installed its own drivers. The wifi would never tun on and enumerate the wireless networks. Installed the Intel Wireless utility and did a repair from Programs and Features and it installed the correct drivers.

This sounds like a bad card.

Was this post helpful? thumb_up thumb_down
I haven't actually checked if disconnecting the LAN brings the WLAN up.

I'll try this next time I am at the client.

Regarding bad card, Would a bad card still show wireless networks?

Check on the computer for HP software called something to effect of "HP Velocity" or anything like "QoS". HP has some default connection management utils that come with the computers and I have seen them do SUPER weirdo stuff sometimes. You'll beat your head against the wall for days and it's just the card driver/software from HP.

Don't know. May depend on what has gone bad. But most probably, a defected card would no longer show wireless networks.

But if your issue doesn't happen when booted without ethernet plugged in, then your card is definitely fine and this HP tool was the culprit. If just plugging off ethernet in a running system and manually reconnecting works then with keeping the WLAN connection, then also this HP tool is the culprit. If in that latter case, a manual reconnect is necessary and shall become able to reconnect automatically, you'll need to update the WLAN configuration in Windows to automatically connect. So if Windows has this WLAN configured to connect automatically and the HP tool configuration was culprit and wasn't changed, the computer should then connect via ethernet as long as ethernet is plugged in and reconnect via WLAN when ethernet gets plugged off.

Scheff1, I have had this issue before and it reacted exactly as described. Also, on some notebook models there is a wifi button on the side to turn it on off. That could be the issue as well.

Yes, it would show the wireless but it can fail to connect. You can also check if there is a setting on your BIOS that turns off the Wireless once the Ethernet is plugged in.

Absolutely.
Since the transmitter component of ANY 2-way radio is FAR more likely to fail than the reciever.

This is by Design in Windows, if the LAN and WAN are connect to the same network

Reg Key use to be this, may have changed in recent builds though??

My HP Pavilion G7 laptop does this too, but only after a Windows update.

When it happens, I have to shut it down, then restart, enable WiFi, shut it down again, and then when it start it up after that, the WiFi will work. I've tried 4 new WiFi cards, and it's done it since I upgraded it to Windows 10 from 8.1. Microsoft have no idea, HP have no idea.

Had this similar issue with a similar model, ended up uninstalling HP Softkey Support and everything was happy as a clam after that.

Who has this legacy software still running? HP declared it legacy and EOL many months ago.

Software and drivers for HP EliteBook 850 G2 Notebook PC

● Check your computer for malware, viruses and then install latest drivers.

● Power Options - Change plan settings - Change advanced power settings
Wireless Adapter Settings - Power Saving Mode = Maximum Performance
There seems to be communication issues in W10 if the setting above is on "power saving".

● Power Options - Change plan settings - Change advanced power settings
PCI Express - Link state power management = disable

● Disable power saving for network adapter
Allow the computer to turn off this device to save power = off

● Disable TCP/IPv6 for network adapter

● Disable/uncheck in Windows "Turn on fast startup (recommended)"
You can do it via Control Panel, registry or GPO.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power]
"HiberbootEnabled"=dword:00000000

● Delete content of all *\Tmp and *\Temp folders and web browser caches.

● Start command prompt as admin and run these commands:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth

● Disable Windows Update via peer-to-peer network

● Some WiFi adapter drivers install also own WiFi management software, which then clash with Windows own management. Uninstall this software.

● Disable Receive Segment Coalescing (RSC)
Open PowerShell as admin and run:
Get-NetAdapter
Disable-NetAdapterRsc -Name "wifi card name from the previous command"
For example:
Disable-NetAdapterRsc -Name WiFi
Disable-NetAdapterRsc -Name "Wi-Fi"

● Configure correctly your AP's.

● Reset Winsock entries and TCP/IP stack:
netsh winsock reset catalog
netsh int ipv4 reset resetlog.txt
netsh int ipv6 reset resetlog.txt

● Clear DNS cache:

ipconfig /flushdns

● Check NetBIOS over TCP/IP configuration that it is not set to act in peer-to-peer mode, which works only with WINS server.

After disconnecting the ethernet cord the WiFi turned itself on and stayed on until plugging the cord back in.

Given it's a Window 10 Pro laptop/PC. (If you're supporting from a remote location, make sure it's connected with Ethernet cable as well.)

Download latest HP wireless driver or downgrade the driver. Most of the time, the current driver can be faulty.

I'd also uninstall Intel ProSet WiFi utility and let Windows to manage WiFi networks.(guaranteed it helps!!!)

1.Go to services.msc

2.Stop WLAN AutoConfig service

3.Uninstall the Wireless driver

4.Reinstall the new driver (you can tell by the driver build date)

5.Turn the WLAN AutoConfig service back on.

Hopefully you can now connect to WiFi without issues.

Cheers.

Are you talking about those Intel drivers which sometimes have a release date some months ahead of their actual release or sometimes several decades behind their actual release? And how do you determine driver build date if you didn't build the drivers?

Was this post helpful? thumb_up thumb_down
Go to device manager-> Expand Network adapters -> Right click the driver -> Properties -> Driver Tab -> "Driver Date"
Sorry I used the term "build date", well you can say "released date" but that gives you the indication of how old the driver is.

I had a similar problem using a VPN connection with WiFi on an HP laptop. Turning off the "LAN/WLAN/WWAN Switching Service" service worked for me.

Hi Richard !

I landed on this thread because... I just had today the same issue with the same computer than yours.

Did you finally solve it ?

Our scenarios are a bit different because I never use the LAN to connect (unless required :-/), only the WiFi. It appeared suddenly when my VPN Client (CyberGhost) warned me that my "VPN virtual card driver was outdated". I close the warning without paying much attention (reason why I don't have the exact warning message at hand) just to realize that I was left without WLAN connection (even with CyberGhost being closed)

So I just wanted to check with you, are you using a VPN client ? CyberGhost for instance ?

Thanks !

Late breaking:

I just encountered the same problem using an HP EliteBook 840. Came immediately after a forced upgrade (not nice, Microsoft!). Switching wifi on from any source (taskbar, wifi button, or network settings) would all cause it to switch off by itself after a few seconds. Since I could clearly see wifi networks appear before it switched off, I assumed there was no problem with the card itself (and see below). I had also tried the BIOS WLAN/LAN switch and the other flags available there, to no avail. I had also upgraded the 7265 card's driver to 18.33.17.1 with PROSet 21.10.1 (WiFi_21.10.1_PROSet64_Win10.exe). I had also reset the BIOS to factory defaults - always a scary option. This took me the better part of two hours, and I got through this fast only because I've been going through this crap for 40 years. I missed a crucial Zoom meeting because of this irresponsible forcing by Microsoft and HP.

The ONLY thing that worked was extremely simple: I explicitly disabled all Ethernet adapters.

I had not had this problem before. What this suggests is that this auto-switching is new logic that came in a later version. Not a good idea, HP! You have cost a lot of people a lot of time! You are not in the business of accounting for it, so who on Earth can add up the lost time for us? What training do you give programmers to prevent this kind of waste??? Or do you simply not care?

This and many other difficult-to-solve problems should serve as evidence and a warning to manufacturers and software engineers to bevery careful about making little tweaks that you think are nice. They can cost people hours, days, and even a high likelihood of simply dumping the laptop and buying a new one, because they assume it is bricked. That's not responsible design!

(The above comments about switching out the network card should be an absolute last resort; it is is NOT good to give advice that a tech-head would find relatively easy [hey here's another EliteBook laptop lying around, I'll just switch it out - versus I have to travel far and wide and spend three days without a computer and spend a fortune, only to find that your solution didn't work] - be VERY careful with treatment options!]
