Recently, I got a Fijian K2P router from Xianyu. The seller has painted K2P_3.4.3.9-099_20170910-2246 firmware without lights in the wilderness. It is found that the firmware is still stable. I am too lazy to upgrade or brush other firmware. However, in the past two days, it was found that 2.4G and 5G could not communicate like AP isolation, that is, terminals connected to 2.4G wireless could not transmit data to terminals connected to 5G wireless, nor could they ping, and vice versa. The most direct response is when the video is played on the wireless screen. For example, my Xiaomi TV is connected with 2.4G SSID, and my mobile phone is connected with 5G SSID. In the mobile Tencent video APP, video cannot be projected to Xiaomi TV. Unless both Xiaomi TV and mobile phone are connected to 2.4G SSID, or both are connected to 5G SSID.

After checking on the Internet, it is said that there is a problem with the MTK bottom driver. At this stage, there should be no firmware to solve this problem. I can only make do with it. If you have a screen projection requirement, you can connect both the projection device and mobile phone to a 2.4G wireless SSID, or both to a 5G wireless SSID.
