Hi,

I installed dd-wrt in my router but the primary wifi 5Ghz speed will not across 70mbps on the phone and 120 on laptop but Ethernet will give me full speed 300 mbps.
Secondary 5Ghz wifi not working at all.
I used dd-wrt last update 12-04-2022 and tried previous updates but this issue on all dd-wrt releases.
I set wifi on highest 80MHz and chose the mode ac only but nothing improved.
I had same issue on D-link firmware 1.21v so i downgrade it to 1.12v
Same this happen on 1.12v if i start Qos so i disable it
In dd-wrt i disable the Qos also but nothing changed.
FYI, i do factory reset before & after update

Welcome to the forum.

Unfortunately you are posting in the wrong forum.

See the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

No problem as I will transfer this post to the appropriate forum.

I think this is one of the routers with an experimental driver which might be better (or not?)

Furthermore have a look at the recommended wireless settings which is a sticky in this forum (BCM best WiFi settings)

please make sure you follow the recommended settings here BCM Best Wifi Settings. For easy troubleshooting, please use different SSIDs for 2.4GHz and 5GHz network. You can take a few screenshots of the wireless basic and advanced page and post here, so that other experts can take a look.
Please also post the model/wifi card of your phone and laptop that you used in your tests. Please post the signal strength shown on your phone & laptop and router sys-info page. Disconnect all other wired/wireless devices from the router while testing.
