ZXHN H6645P is the second-hand product I purchased
I already have an administrator account and password
But my wireless 5G download speed is extremely slow, but uploading is normal
The currently selected 36 channels with a bandwidth of 160MHz
Add it up
I have opened the casing, and the circuit board inside is as follows. The shielding cover is soldered dead
Is there a problem with the 5G wireless chip?
Can anyone provide the firmware for H6645P? I would like to upgrade and take a look
