Sporadic Internet Connectivity HP All-in-One Desktop 24

[PatReason]

Hi, I have a new HP All in One desktop. The problem is the wifi goes out indiscriminately.  All other devices on the network retain connections.  I have run diagnostics and searched for fixes. I thought it was fixed when I turned off power saving on the realtek hardware and set the aggressiveness to minimal.  No such luck with that fix. I have updated drivers, run every test but the problem persists. I can usually bring the wifi connection back by simply clicking on connect again but this is annoying.  Any help would be greatly and sincerely appreciated.

@PatReason,

Welcome to our HP Community forum!

Outstanding job -you've done excellent troubleshooting already: updating drivers, disabling power saving, and adjusting roaming aggressiveness were all good steps.

Here are a few more things to check that often help when an HP All-in-One intermittently drops Wi-Fi connections:

1. Forget and reconnect to your network

   • Go to Settings → Network & Internet → Wi-Fi → Manage known networks.

   • Remove your current network, then reconnect and re-enter your password.

2. Turn off "Random hardware address"

   • Under Wi-Fi settings → Manage known networks → [your network], toggle Use random hardware addresses off.

   • This can improve stability with Realtek adapters.

3. Check HP background services

   • On some HP systems, HP Connection Optimizer or HP Network Check Helper can cause brief Wi-Fi resets.

   • Try disabling them temporarily via services.msc to see if stability improves.

4. Reset your network stack

   • Open Command Prompt (as Administrator) and run (copy/paste/Enter) each command separately:

     netsh int ip reset

     netsh winsock reset

     ipconfig /flushdns

     Then restart the PC.

5. Adjust adapter settings

   • In Device Manager → Network adapters → Realtek → Advanced, try setting:

     • ARP Offload = Disabled

     • NS Offload = Disabled

     • Roaming Aggressiveness = Medium or Medium-Low

6. Disable "Fast Startup"

   • In Control Panel → Power Options → Choose what the power buttons do, uncheck Turn on fast startup.

   • This prevents the adapter from occasionally “waking up” incorrectly from sleep.

7. Check signal strength and interference

   • All-in-One PCs have internal antennas that can be more sensitive to placement. If the router is far away, or behind walls or metal objects, the signal may weaken or fluctuate even if other devices nearby remain stable.

   • Try moving the PC temporarily closer to the router. If the issue disappears, a Wi-Fi repeater, mesh extender, or powerline adapter placed near the desktop should solve it.

8. Router compatibility

   • If your router supports both 2.4 GHz and 5 GHz, try connecting only to one band. Some Realtek chipsets are more stable on 2.4 GHz.

If the problem persists, please post the exact model number (for example, HP All-in-One 24-cb0000) — HP sometimes provides model-specific driver or firmware updates that address connection stability.
