From what I can tell, this is a common concern. So this post is just asking if I understand this correctly and if there's anything else I can look at to improve my download speed.
I have an archer c7 v2, been running an older version of dd-wrt for a couple of years hooked up to a relatively slow cable modem 25d/5u.
Last weekend, we upgraded said cable modem speed to 300d/15u. At the cable modem, I can confirm those new speeds. But connecting through the archer, I can only get at most 90d/15u, and frequently less on the download speed. This is regardless of wired or wireless connection, at 2.4 and 5Ghz.
I've seen a few references in this forum to this being caused by the HW NAT issue and by the CPU frequency of this router. But it also appears that I should be able to get near 150d, which I'm not. I have tried various recommendations from posts here but none seem to make any difference.
