Posted: Tue Sep 15, 2020 23:17 Post subject: Slow speeds
So, Iv'e just started using dd-wrt again. Previous router was a Linksys that worked great till you could no longer log into it and it is not supported by dd-wrt. So, went with an Asus RT-AC68U running the 44340 firmware. My issue is with the speeds, they are almost cut in half. With the Linksys on 1GB service, speeds were around 940MB and when on 500MB service, speeds were around 550MB down, our ISP over provisions by 10%, except for the GB speed. Iv'e tried two other dd-wrt firmwares with the same results. Is this all this router is capable of, or am I missing a setting somewhere? Haven't tried the SFE setting yet. Is there a router that will handle the GB speeds running dd-wrt? Model, make, etc. Sorry for so may questions. Thanks.
Edit: did try the SFE setting and it does help, anything wrong with leaving this enabled?
Edit again: now with SFE enabled, wireless speeds are horrible, guess I'll keep messing with it.

After some research and playing with some settings, here's what worked for me on a 500 MB download and 125 MB upload from our ISP. Our ISP also over provisions by 10%. This is on the: Firmware: DD-WRT v3.0-r44340 std (09/10/20).
Under Setup, Basic Setup: Set Shortcut Forwarding Engine (SFE) to Enable. This is a must!
Under Wireless, Basic Settings, wl0 2.4 GHz: Wireless Channel: Select a channel that is clean with no overlapping signals from other AP's in the area. Mine was channel 11. Can be "seen" using the WiFi Analyzer App on a phone.
wl1 5 GHz
Wireless Channel: A good clean channel with no overlapping signals from other AP's around you. Mine is channel 100.
Channel Width: VHT 80
Explicit Beamforming: Enable
Implicit Beamforming: Enable
Wireless Security: WPA2-PSK (AES) on both 2.4 and 5 GHz.
