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'
