Good morning, That's right. I tested one (the price is worth the diversions), but unfortunately, the speeds aren't there. It lacks that frequency range. I had to check it out by looking at the specs on their site. The best router I've tested so far is the DECO (5G+wifi6) - you need to configure it with your mobile phone. The simplest is the ZTE MC801A, which works straight out of the box

So the N78 band is missing?

Yes should flaps
