16 Plus DB16250, Random Reboots and Loss of WIFI

Called Advance Tech support - huge echo on the line then they just hung up - appalling service.

If I can add I'm quite deaf and there seems no alternative to an impossible phone call.

@DELL-MacarthurD​ Dell 16 Plus DB16250

@DELL-MacarthurD​ 

I hope I have the following sequence right!

Installed drivers and restarted.

Some websites slow, then internet dropped out.

Restarted again some websites slow then internet dropped out.

Ran the diagnose network problems said "using a network adaptor we couldn't test"

Then "can't reach default gateway"

Restarted ethernet network adaptor but nothing seemed to happen.

Restarted third time some sites quick (X) some slow (Dell.com!) internet dropped out again.

Diagnose network problems again "Wifi is turned off" starting it did nothing other than trying to commect (wifi icon bottom right hand corner of screen)

Did a netwok reset via advanced settings.

Restarted some websites slow still but it hasn't disconnected!

Checked for updates on Dell Support Assist 0 software updates found.

So the new drivers seemed to make it worse?? But surely I must be uptodate anyway as no updates were found?

(My current network adaptor driver shows as intel dated 6/1/26 version 24.20.0.4 - I'm not sure if my network reset overwrote your version. BIOS Version/Date is Dell Inc 1.12.0 31/3/2026.)

try this please

1. Click  Settings > Control Panel.
2. Double-click Network Connections.
3. Right-click the wireless connection and click Properties.
4. Click Configure.

Click the Advanced tab.
Select the Power Management setting, uncheck Default / Auto, and move the slider to Highest / Maximum Performance.

Try this after as well if issue still persists 

Run Command Prompt as Administrator

1. Type netsh int ip reset c:\resetlog.txt then press Enter
2. Type ipconfig /release then press Enter
3. Type ipconfig /renew then press Enter

Restart the computer

If issue persist flush the DNS and reset WINSOCK

1. Type ipconfig /flushdns then press enter
2. Type netsh winsock reset then press enter

Let me know once you’ve completed these steps, and if the problem persists, I’ll be happy to assist .

Hi

First off...

Description                       Option one                                             Option two
Model number                 Intel AX211                                            Intel BE201
Transfer rate                    Up to 2400 Mbps                                  Up to 5760 Mbps

So I assume the driver covers both types adequately. 

Try any, some, all or none of the following...

getmac & netsh interface ip show interface

netsh wlan show interfaces & netsh lan show interfaces

powershell Get-NetConnectionProfile

netsh wlan show drivers & powershell get-netadapter

You can, of course, try and pipe the output to a text file, EG:

netsh wlan show interfaces & netsh lan show interfaces > c:\users\show.txt

Which should ID the individual card and some of it's properties.

If in doubt please ask.

@DELL-MacarthurD​ sorry I don't have those options.

When I access settings from the cog wheel my option is Network and Internet

It I access by typing in control panel I get the below and perhaps this setting is allowing a reboot rather than a sleep mode?

The only power management I can find is in the control panel

Howevr, it did not reboot overnight or lose WIFI (I had no apps - oiutlook or any browser running.) Although when firing up chrome some websites are still slow to load.)

@anne_droid​ this is my card (in the  reply to MacArthur)nso a bit different?

Hi

Perhaps stay with the status quo for now.

@anne_droid​ I did get a reboot and an internet loss earlier but it found it again. I'll leave it on with a few different things running and see it it's a particular app that's an issue.

Thanks

Again
