I just installed Open WRT everything went alright, but I'm not able to achieve speeds higher than 30 Mbps (Got 160 Mbps at home), started with version 18.06.1, reading some posts then I installed the ath79 version, and enabled HW NAT, I still have the same issue.
I don't know if it is because my ISP is already doing NAT on their device, but I didn't have that issue with my previous router.
Gotta mention that if I disable DHCP, and plug this router as a switch + access point, it works with full speed.
Any idea or pointer on what to look for would be really appreciated.
It helps others to edit the post thread to start with [Solved] or the like, as well as using the "solution" checkbox (which will reference that post in the lead post).
