When using original firmware from tp-link, it behave normally.
I try to decrease wifi power to the minimum, but no change.
is there another way to increase power on usb rather than using powered
hub?
adding capacitor maybe?

When using original firmware from tp-link, it behave normally.
I try to decrease wifi power to the minimum, but no change.
is there another way to increase power on usb rather than using powered
hub?
adding capacitor maybe?

When using original firmware from tp-link, it behave normally.
I try to decrease wifi power to the minimum, but no change.
is there another way to increase power on usb rather than using powered

adding capacitor maybe?

When using original firmware from tp-link, it behave normally.
I try to decrease wifi power to the minimum, but no change.
is there another way to increase power on usb rather than using powered
hub?
adding capacitor maybe?

I tried "iw phy0 info" and I notice the txpower still shows "20dBm"

I think the problem might because of huawei E-169, I changed txpower from
default -> 20 -> 18 -> 14, it still drop.

but huawei E-1782, no problem now, wifi also is very stable.

I tried "iw phy0 info" and I notice the txpower still shows "20dBm"
whatever you put in /etc/config/wireless.

When using original firmware from tp-link, it behave normally.
I try to decrease wifi power to the minimum, but no change.
is there another way to increase power on usb rather than using powered
hub?
adding capacitor maybe?

I think the problem might because of huawei E-169, I changed txpower from
default -> 20 -> 18 -> 14, it still drop.

but huawei E-1782, no problem now, wifi also is very stable.
