Hmm, you're right, I might be misremembering and was actually using 80 MHz, so I wanted to try 160 MHz but the routers did not support that. Right, so Wifi N ha

Hmm, you're right, I might be misremembering and was actually using 80 MHz, so I wanted to try 160 MHz but the routers did not support that. Right, so Wifi N had 20/40 MHz. Thanks! Reading the replies I'm thinking better chipsets could've achieved higher speeds, but that doesn't quite make sense - if the negotiated rate is the same, why would the real speed differ between routers? I used Archer C7s, which I love because I'm poor, very cheap, very reliable with OpenWRT. I ended up running fiber - it was surprisingly cheap and I didn't even need special tools for the connectors, just have to be veeery careful when cutting and inserting the cable.
