I have set up a Netgear R7800 router on openwrt 21.02.3.
It is in bridge mode, behind the ISP router.
When I enable the ISP's router 2.4Ghz wifi, I get speeds of 95 Mbps (close to the 100 Mbps I am paying for).
On the openwrt router (R7800), the 5GHz wifi is perfectly fine. However, the 2.4GHz wifi is very slow. I achieve about 20 Mbps, sometimes dipping to 15 Mbps.
Can anyone with the R7800 share their experience with 2.4GHz speed ?
Here's my /etc/config/wireless (the 2.4Ghz part) :
config wifi-device 'radio1'
option type 'mac80211'
option band '2g'
option path REDACTED
option htmode 'VHT20'
option cell_density '0'
option channel 'auto'
config wifi-iface 'radio1_net'
option device 'radio1'
option network 'net'
option mode 'ap'
option key REDACTED
option ssid 'net'
option encryption 'sae'
option wpa_disable_eapol_key_retries '1'
option ieee80211w '1'
option isolate '1'
option dtim_period '3'
