| + | ==== BPI-R4-NIC-BE14 ==== | ||
| + | One of the greatest advantages of this device is the cooperation of the main processor (MT7988) with the WiFi module (**MT7996**). | ||
| + | The **BPI-R4-NIC-BE14** module is often described as a board with MT7996 processor, but this is actually a marketing shorthand used by MediaTek | ||
| + | for its Wireless module series. The MT7996 refers to an entire chipset package consisting of multiple components: MT7995AV+MT7976CN+MT7977IAN. | ||

| + | === Wireless Offload === | ||
| + | |||
| + | Before explaining the WO firwmare goal, it is worth to mention about **WED** - **W**ireless **E**thernet **D**ispatch. (Special thanks | ||
| + | for Dangowrt for the explaination). | ||
| + | |||
| + | The WED term stems from the original implementation which is part of MT7622 and offloads | ||
| + | forwarding from Ethernet to Wireless, ie. WiFi TX is offloaded only. Hence packets received on Ethernet | ||
| + | are dispatched to Wireless, hence the name. More recent versions (MT7986, MT7981 and later SoC) do | ||
| + | support also taking care of the traffic received on the Wireless interface. | ||
| + | |||
| + | The " | ||
| + | offloading firmware is required. | ||
| + | |||
| + | WED means offloading traffic forwarding from/to Wireless. It works with the existing | ||
| + | flow-offloading aka. HWNAT engine of MediaTek SoCs, just like for forwarding Ethernet traffic. | ||
| + | Newer SoCs need firmware to perform WED, and that is called WO firmware. Because WED is now bidirectional, | ||
| + | MediaTek started to use the more generic term WO instead of WED, which suggests a unidirectional | ||
| + | nature as it has been the case on MT7622. Today, the two terms (WED and WO) mean the same feature. | ||

| + | To set 2GB RAM limit, you need to execute on the router: | ||
| + | < | ||
| + | fw_setenv bootargs " | ||
| + | </ | ||
| + | |||
| + | To go back to previous settings, execute on the router: | ||
| + | < | ||
| + | fw_setenv bootargs " | ||
| + | </ | ||
| + | </ | ||
| + | |||
| + | After you change RAM size (temporary workaround), | ||
| + | |||
| + | < | ||
| + | echo " | ||
| + | </ | ||
| + | |||
| + | Then **reboot** the router to apply changes. When it comes back, results should be as below: | ||

| + | === 6GHz wireless network === | ||
| + | |||
| + | The topic of 6GHz networking is often duplicated on the official OpenWrt forum, so before | ||
| + | configuring your network, make sure: | ||
| + | |||
| + | * if you are using Windows 10, using the 6GHz network is not possible on this system, | ||
| + | * make sure you have the latest drivers, | ||
| + | * verify the Wi-Fi [[https:// | ||
| + | * there are only few contries where the 320MHz width can be used | ||
| + | |||
| + | <WRAP BOX> | ||
| + | **NOTE**: Sometimes the latest drivers may not achieve satisfactory speeds. It is worth trying sometimes to use **AX** mode than **BE** mode. | ||
| + | </ | ||
| + | |||
| + | ==== Testing speed locally ==== | ||
| + | There are many tools to check the speed between the host and the router. The most commonly | ||
| + | used, " | ||
| + | " | ||
| + | convenient method for testing (by default the service should be available on port :8989). | ||
