I can't agree with that, I use the device for streaming (high-resolution), video conferencing and much more, sometimes in parallel, and as long as you have a 5G network behind it, none of this is a problem.

I also used this router for several years and always had good WiFi reception - I can't confirm that.
Nevertheless, I would recommend everyone to buy the Oppo T1a instead of the Huawei router. For me, the Oppo has replaced the Huawei and in the meantime I have also tested the Xiaomi 5 CPE and the Oppo 5G CPE T2 in comparison. In terms of download rates, none of them achieve the same speed as the Oppo T1a, although the T1a uses the older X55 chipset instead of the new X62. The Oppo 5G CPE T2 was better in terms of upload rates. I bought the Oppo CPE T2 from Sunrise but will sell it again and continue to use the Oppo T1a.

But I don't agree. The response time is very good and the bandwidth is one of the best obtained with this type of device. I've been using it for several years now and it manages my home automation services, including cameras, at my company. Not being able to have a fixed line, I opted for this product. I even put IP telephony on it via VPN direct to my home and it works! So I don't agree with this opinion. You also need to look at the location of your router and the subscription you choose with your operator. As far as I'm concerned, I've got a good 5G with Swisscom as a SIM card secondary to my Natel subscription.
