most Asus routers are made by Arcadyan - I did not wrote it as bad think. It is even possible that if Asus will manufacture them they would be worst
made in China is not bad info too - China have now the most advanced manufacturers process. It is our fault we think China is bad quality as a customers we want to buy all very cheap from China.
It's probably more accurate to say China has the best and worst manufacturing in the world.
Their reputation is tarred by the millions of eBay / Amazon sellers who have flooded Western markets with tat off of Alibaba.
I'm sure most people here have brought something from China that has broken a week later. On the flip side, I know people who own Chinese smart phones and accessories that are very well made.
A few years ago I purchased a pair of Xiaomi earphones in large part because I wanted to test their quality (they were discounted at that time). They turned out to have great build quality, and also had better packaging than a lot of the usual well known household brands (like Sony), indicating more attention to details, and less to cost savings. No cheap and horrible plastic clamshell for instance.
Likewise, I only have good things to say about my Huawei P30 phone, both in terms of performance and build quality.
The manufacturing country means absolutely nothing.
