This code attempts to modify dev->mtu and dev->features before dev is initialized. The variable dev is declared on line 25 but not assigned until after usbnet_probe(intf, id) is called on line 47. This will cause a null pointer dereference and crash. This code block should be moved to after the device is properly initialized by usbnet_probe, or implemented in a different callback.

+	phy->mt76->aggr_stats[0] = 64;
+	phy->mt76->aggr_stats[1] = 128;


The aggr_stats array appears to be misused. Based on the variable name and typical kernel usage, aggr_stats is likely for tracking aggregation statistics, not for configuring aggregation sizes. Setting statistics array elements directly like this is incorrect and won't configure aggregation behavior. The proper way to configure aggregation would be through appropriate configuration fields or macros defined in the MT76 driver.

Suggested change

+ phy->mt76->aggr_stats[0] = 64;

+ phy->mt76->aggr_stats[1] = 128;

+	wiphy->bands[NL80211_BAND_6GHZ]->ht_cap.cap |= IEEE80211_HT_CAP_SUP_WIDTH_20_40;


This code attempts to set HT capabilities on the 6GHz band, but 6GHz (WiFi 6E/7) doesn't use HT (High Throughput - 802.11n). The 6GHz band uses HE (802.11ax) and EHT (802.11be) capabilities instead. HT is only relevant for 2.4GHz and 5GHz bands. This line should either be removed or replaced with appropriate EHT capability configuration for 6GHz.

Suggested change

The AT command outputs are being redirected to the device file without capturing or checking the response. This means the script cannot verify if commands succeeded. The response=$(echo "ATI" > "$device" 2>&1) on line 47 also won't work as expected because redirecting to a file doesn't produce output to capture. Consider using proper AT command tools like comgt or reading responses from the device, or at minimum check exit codes if available.

+for device in /dev/ttyUSB*; do
+    if [ -e "$device" ]; then
+        # Check if it's a Quectel modem
+        response=$(echo "ATI" > "$device" 2>&1)


The modem detection logic is flawed. The command response=$(echo "ATI" > "$device" 2>&1) redirects output to the device file and won't capture any response. Shell redirection to a file doesn't produce stdout to capture in a variable. This means $response will always be empty, and the grep check on line 48 will never succeed. The script will never actually apply optimizations to any modem.

Suggested change

response=$(echo "ATI" > "$device" 2>&1)

response=$( (echo "ATI" > "$device"; sleep 1; head -n 10 "$device") 2>/dev/null )
