When attempting to connect a Motorola MC3190 device to a WPA2-PSK secured WiFi network using Symbol Wireless Fusion tools, the device detects the SSID but fails to associate. The Wireless Status log shows:

[INFO] Setting SSID: MyWiFiNetwork
[ERROR] Association timeout

This occurs approximately 10 seconds after the SSID configuration attempt.

Since the MC3190 appears in the "Find WLANs" scan results, we can confirm:

• The 802.11 radio is functional
• Basic beacon reception is working
• The correct security protocol (WPA2-Personal) is selected

The association timeout suggests a failure during the 4-way handshake process. Common root causes include:

// Typical WPA2 handshake sequence that might fail
1. Authentication Request
2. Authentication Response
3. Association Request
4. Association Response (timeout occurs here)

Check these critical parameters in the Wireless Fusion profile:

Security Mode = WPA2 - Personal
Encryption Type = AES (not TKIP)
Pre-Shared Key Format = ASCII (if using passphrase)
Key Length = 64 hex chars or 8-63 ASCII chars

For deeper analysis, capture the handshake attempt:

# tcpdump filter for WiFi association
sudo tcpdump -i wlan0 -n -s 0 -w mc3190.pcap '(wlan.fc.type_subtype == 0x00 || 
wlan.fc.type_subtype == 0x01 || 
wlan.fc.type_subtype == 0x0b)'

Look for missing management frames or malformed EAPOL packets.

Some MC3190 firmware versions have known issues with certain AP chipsets. Try:

1. Upgrade to the latest Fusion firmware
2. Enable "Legacy WPA" mode if available
3. Reduce the beacon interval on the AP to 50ms

As a temporary solution, use the Windows CE registry editor to configure WiFi:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\Comm\XYZWiFi\Parms]
"PreferredDataRates"="1,2,5.5,11"
"BGScanEnabled"=dword:00000000
"AuthMode"=dword:00000004
"Encryption"=dword:00000004
"PSK"="YourWiFiPassword"

Verify these access point settings:

• Disable 802.11n/ac/ax features (MC3190 is 802.11a/b/g only)
• Set channel width to 20MHz
• Disable WMM (WiFi Multimedia) QoS
• Disable any MAC address filtering

When all else fails, reset the WiFi configuration:

1. Hold Power + Scan + 1 + 9 during boot
2. Select "Clean Boot" from menu
3. Reinstall Wireless Fusion software
4. Recreate WLAN profiles from scratch

The MC3190 handheld shows the SSID in wireless scans but fails to complete association, timing out after approximately 10 seconds. The Fusion Wireless Status log specifically shows:

[WLAN] Setting SSID: YourNetworkName
[WLAN] Association timeout

The problematic configuration involves:

• Security Mode: WPA2-Personal (AES)
• Radio: 802.11b/g (MC3190's default)
• Management: Symbol Wireless Fusion 5.x/6.x

First, verify the radio state with this PowerShell snippet for Fusion:

$wlan = New-Object -ComObject Symbol.Wireless.WLAN
$wlan.GetRadioState() | Format-List

If radio state shows "Enabled", proceed to profile inspection:

$profile = $wlan.GetProfile("YourProfileName")
$profile.SecurityMode    # Should return 4 (WPA2-Personal)
$profile.CipherType      # Should return 3 (AES)

1. Channel Width Mismatch
Some APs default to 40MHz channels while MC3190 expects 20MHz. Modify the profile:

$profile.ChannelWidth = 0  # 0=20MHz, 1=40MHz
$profile.Save()

2. PMF Compatibility
Newer WPA2 implementations may enforce Protected Management Frames. Add registry override:

RegWrite "HKLM\Comm\Security\WPA2", "DisablePMF", 1

Enable verbose logging through Fusion CLI:

wlancfg.exe /l 3 /f C:\wlan_debug.log
wlancfg.exe /a YourProfileName

Check for these critical log entries:

[WPA] 4-Way Handshake Started
[WPA] Received Message 1/4
[WPA] PTK derivation failed      <-- Indicates PSK mismatch

When all else fails, perform a clean reset:

1. Hold Power + Scan + Action buttons during boot
2. Select "Clear All Data"
3. Recreate WLAN profile from scratch
