Need help with my ASUS B650E Max Gaming WiFi

General

I’m having trouble with my ASUS B650E Max Gaming WiFi motherboard after a recent build, and I can’t figure out why it’s acting up. It started having boot and WiFi issues, and I need help troubleshooting the cause so I can get my PC running normally again.

Start with the simple stuff. Boot issues and WiFi issues on an ASUS B650E board often point to BIOS, RAM training, or chipset and WiFi drivers.

Do this in order.

  1. Update BIOS with EZ Flash.
    Use the newest stable BIOS from ASUS. Early AM5 BIOS versions had lots of memory training and boot weirdness. If you built recently and the board shipped with an older BIOS, that alone can cause long POST, failed boots, and random device problems.

  2. Load BIOS defaults.
    After update, clear CMOS. Then run stock settings. No EXPO, no PBO, no undervolt. Test first. Bad EXPO settings are a common cause of boot loops on B650 boards.

  3. Check RAM placement.
    Use A2 and B2 only. Reseat both sticks. If it still acts up, test one stick at a time. If one stick boots clean and the other does not, you found a lead.

  4. Watch the Q-LEDs.
    This board should show CPU, DRAM, VGA, BOOT debug LEDs during POST. If it hangs on DRAM, focus on memory. If it hangs on BOOT, check your SSD and boot order.

  5. Reinstall AMD chipset drivers and WiFi drivers.
    Get both from ASUS first, then test AMD and MediaTek or Intel direct if needed, depending on which WiFi chip your board has. In Device Manager, remove the WiFi adapter, check the box to delete driver files, reboot, reinstall. Also turn off Windows power saving for the adapter.

  6. Check antenna and signal.
    Sounds dumb, but a loose antenna tanks WiFi stability. Make sure both leads are on tight. If speeds are trash or it drops out, test with the PC next to the router for 10 mins.

  7. Rule out PSU and storage.
    If boot issues started after adding parts, unplug extras. Run one SSD, one RAM kit, GPU, nothing else. A flaky PSU rail or bad NVMe causes weird boot behavior too.

  8. Look in Event Viewer.
    WHEA errors, driver resets, or device disconnects matter here. If you see WHEA 18 or memory-related errors, I’d suspect BIOS, RAM, or CPU memory controller.

If you post full specs, BIOS version, RAM kit model, and which Q-LED gets stuck, people here can narrow it down fast. Right now my first suspect is EXPO or old BIOS. ASUS AM5 boards were kinda fussy early on, no lie.

I’d add one angle that @suenodelbosque didn’t really hit: make sure this isn’t a Windows corruption or lane-sharing problem pretending to be a motherboard issue.

A few checks:

  • In BIOS, verify the NVMe drive is detected every single boot. If it disappears randomly, that’s not a WiFi problem, that’s storage or slot-related.
  • Try the other M.2 slot if your boot drive is in one of the shared lanes slots. On some boards, using certain M.2/SATA combos causes weirdness people blame on the board.
  • Disable Fast Startup in Windows. It causes fake “boot issues” way more often than ppl admit.
  • Run sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth.
  • For WiFi, boot a Linux live USB. If WiFi is also unstable there, it points to hardware, antenna, or BIOS. If Linux works fine, Windows driver stack is probly the mess.
  • Check Device Manager for Code 10/43 and hidden devices. Sometimes the adapter keeps ghost entries after bad driver installs.
  • Reseat the WiFi module if it’s an M.2 E-key card and not soldered down.

Also, I slightly disagree with blaming PSU early unless you’re seeing shutdowns, black screens, or USB flakiness too. Boot + WiFi together smells more like BIOS/driver/storage jank than raw power.

I’d go one layer lower than what @suenodelbosque covered and look at board training, not just OS or drivers.

For AM5, memory instability can show up as “random boot issues” long before it looks like a RAM problem. If EXPO is on, turn it off and run JEDEC defaults for a while. Also update chipset drivers after BIOS, because stale AMD chipset packages can cause weird PCIe and network behavior.

A few things I’d check:

  • Clear CMOS fully, then load optimized defaults
  • Leave only 1 RAM stick in slot A2 and test boots
  • Move USB devices off the rear panel except keyboard, since bad USB peripherals can hang POST
  • Check the WiFi antenna leads are firmly snapped on. Weak or unstable WiFi is often just antenna connection, not the ASUS B650E Max Gaming WiFi board itself
  • Inspect CPU socket pressure. Overtight coolers on AM5 have caused odd POST behavior
  • Watch the Q-LEDs during failed boots. The LED color tells you whether it’s DRAM, VGA, CPU, or boot stage

Where I slightly disagree with @suenodelbosque is on PSU suspicion. Not first guess, sure, but marginal power can absolutely show up as flaky initialization before full shutdowns start.

Pros for the ASUS B650E Max Gaming WiFi: strong feature set, PCIe 5 support, decent BIOS options.
Cons: AM5 memory training can feel finicky, early BIOS versions can be temperamental, onboard WiFi issues are sometimes antenna or driver-sensitive.
