They don’t have a hardware problem, they have a software issue.
The same device with ipq4018 so performe well from another vendors, have more functions and deliver more speed to more devices, this is all about software, a piece of software that has an 6 years old kernel.
There is no issue with functionality they are added more and more, but there are issues with the basic.
If you use an old kernel and you want new hardware support. You have do to that by your own, and this is the problem, Mikrotik Wireless Drivers support newer chipsets only with basic features, and that is why they
- don’t perform well
- we Are misssing Spectral Scan, Wave 2 and more
- they have compatibility issues
On 4011 all Intel ac clients only connecting with 54MBit, my friend have new Asus Router with the same Chipset, and what does my Intel ac Laptop?
Connecting with 1300 MBit, welcome to Mikrotik legacy Wireless world, they had done an Business decision, and there is no Future for
Outdoor Wireless, but they don’t Tell US.
Shure they can build something like AF, but this would take years, you would no see anything in 2019 and. 2020, and we don’t need more new ARM Based ac Hardware until the Software issues are fixed.
This issue is known for 12 month now..,
