It sounds like your Archer TBE550E is having issues with Windows 11’s power management. Even with the latest driver, Wi-Fi adapters sometimes fail to auto-reconnect after sleep/hibernate. Try these steps:

1. Disable power saving for the adapter:

   • Go to Device Manager → Network adapters → Archer TBE550E → Properties → Power Management → uncheck "Allow the computer to turn off this device to save power".

2. Disable Fast Startup:

   • Control Panel → Power Options → Choose what the power buttons do → Turn off fast startup.

3. Set Wi-Fi profile to auto-reconnect:

   • Settings → Network & Internet → Wi-Fi → Manage known networks → select your network → set "Connect automatically".

4. Optional: Check for Windows updates or router firmware updates, as Wi-Fi 7 is new and may have compatibility fixes.

If issues persist, sometimes a clean driver uninstall and reinstall (or using TP-Link’s installer instead of Windows driver) resolves reconnection delays.

  @James-Miller_23, @JavaJim, 

I have the TBE550E on Win11 Home running the latest f/w (Driver 5.4.0.3119) listed on the D/L page for drivers,  Archer TBE550E(US)_V1.60_20250703_Win11 and I do NOT have that problem.

In addition to the above 'settings', another to look at is IN your POWER PLAN for Link State Power, I've got it OFF:

This disables power-saving on PCIe links, which can potentially improve performance in some cases by eliminating the delay that occurs when a link wakes up from a low-power state.
