I installed Surfshark wireguard on my router last night. There has been a significant drop in speeds and the 5ghz is really slow and frequently drops. My wired connection went from 600-980 to 25-30 mbs. I'm really at a loss as to how to remedy this. I want the added security and convenience of wireguard on the router but these speeds are unacceptable. I Appreciate any and all help in advance. Thanks
I got lucky I guess. I had been fooling around with it all day until i came across the post and it solved my problem. I have only been dealing with openwrt for almost 24hrs but I'm still figuring things out trying to get my footing. Just need help figuring thing out as to not cause more harm than intended. I see the packages you posted and I will look for the one that contains the htop installation. Thank you for your help
You shouldn't get more than around 30 MBit/s running Wireguard with this device due to its CPU limitations. For me the last OpenWrt release that got around 60-70 MBit/s with Wireguard on Archer C7v4/v5 was v19. Others have reported similar drops in speed between v19 and v21, with no changes on v22 and v23.
I have to say though, that it looks off seeing your CPU not being used by more than a couple % - did you run a speedtest on a device connected to the router while checking htop? Htop should inidicate your CPU being (close to) maxed out then.
