wonderful model, really honored

In my opinion, Huawei is actually one of the best manufacturers of networking equipment. And this modem 3372 - 325 is proof of that.
No installation issues. Just enter the IP address and click Yes three times. On Windows 11, it runs like a charm. Speed comparable to a cable (copper).
No drawbacks. And what shortcomings could Huawei possibly have?
Huawei overcomplicated with the modem.

Do not buy this modem. I took it as a backup option in case of the absence of a PON network. After the second attempt, the seller refunded the money.
Not Available
Breaks the connection with the provider as the modem pleases. It might work for an hour, or it might disconnect after 10 minutes.

Works as expected. Everything depends on network coverage. The speed is enough to watch YouTube videos in 1080.
Compact, does not require complex setup, stable speed (if the network is stable), does not require additional power supply
i believe that in such devices, the only drawbacks are when they glitch and don't work as stated by the manufacturer, but I haven't noticed that here.
