In many threads like this, replies try to educate the OP about the difference between speeds on the wired WAN interface and WiFi speed. This is all very interesting.
But the fact remains that in many scenarios, Flint 2 routers deliver much lower speeds compared to other routers on the same ISP connection, both wired and wireless. In my case, my cable connection is supposed to deliver 1000 Mbs download and 50 Mbs upload.
My Asus router (almost) matches these numbers for wired connections, and reaches 700 Mbs download and 50 Mbs upload for wireless connections. My new Flint 2 router performs reasonably well for wireless downloads (up to 600 Mbs), but only gets to 5 Mbs upload at best (in many cases, uploads top out at 1 Mbs), along with packet loss between 5 and 20%. There are no other WiFi networks around, I only activated the 5 Ghz network.
So this is not a theoretical discussion about what you can and cannot expect from a WiFi network in principle, but the actual performance of a WiFi router.
I tried everything suggested in another post, namely:
- updated to firmware 4.8.0-op24
- placed a gigabit switch between cable modem and Flint 2
- power-cycled everything
and I also turned off hardware acceleration (which did help a bit). IPv6 was turned on already, using the passthrough mode. This is on a Vodafone cable connection in Germany.
Still, if I do not find a solution that brings the Flint on par with my old Asus router, I will have to return the Flint 2. Which would be a shame, since there are many things I really like about it.
