OK AI bot I have been playing with the flint 4 wifi and had to use the ssh command to restore the 3 wifi bands but now I do not have the option to congigure / use MLO - the option is not in the GUI. How do I enable MLO or get the MLO option back in the wireless GUI. ---

Please provide the **exact SSH command(s)** used to restore the three Wi‑Fi bands and the Flint 4 firmware version shown under **SYSTEM → Upgrade**. The MLO entry can disappear when the wireless configuration is rebuilt or changed outside the GL.iNet interface; these details will determine whether the change can be reversed safely or whether the wireless configuration must be regenerated. Avoid making further SSH changes for now. A factory reset may restore the default MLO configuration, but it would erase your settings, so it should not be the first step. > **This reply was generated by AI.

`wifi config` rebuilt `/etc/config/wireless` as a basic OpenWrt configuration; it does not recreate the GL.iNet MLO configuration and GUI metadata. Since you made a backup first, test restoring it: ```sh cp /etc/config/wireless /etc/config/wireless.generated cp /etc/config/wireless.backup /etc/config/wireless wifi reload ``` Wi-Fi will disconnect briefly. Refresh the Admin Panel and check whether **WIRELESS → MLO Wi-Fi** returns. This also restores the previous wireless state, so the missing-band issue may return. If that happens, keep both files and avoid running `wifi config` again; firmware 4.11.0 beta3 will likely need its vendor wireless configuration regenerated through a factory reset or firmware reinstallation without retaining settings, which erases the current configuration. > **This reply was generated by AI.

The copy failed before changing `/etc/config/wireless`, so `wifi reload` only reloaded the current generated configuration. The `killall` messages are harmless in this context. Also, you are correct: restoring the old file would have restored the original broken Wi‑Fi state, so that was not a suitable next step. There is no backup available at the stated path, and `wifi config` cannot reconstruct Flint 4’s GL.iNet MLO configuration. The reliable recovery is now to reinstall the Flint 4 firmware through **SYSTEM → Upgrade → Local Upgrade** with **Keep Settings disabled** , then configure the router again manually. This erases the current configuration but allows the firmware to regenerate its vendor Wi‑Fi and MLO defaults. Do not restore a full configuration backup afterward, because it may restore the damaged wireless configuration. Keep the router powered on throughout the installation. > **This reply was generated by AI.

Hi, Sorry for the late reply. If convenient, we recommend resetting the router to factory defaults, as this is the simplest way to restore the original Wi-Fi and MLO configuration. Alternatively, you may refer to the following post, which provides SSH commands for manually creating a Guest MLO Wi-Fi network: > [@Multiple MLO Networks](https://forum.gl-inet.com/t/multiple-mlo-networks/71644/6): > > Please try connecting to the router via [SSH](https://docs.gl-inet.com/router/en/4/tutorials/ssh_log_in_to_the_router/) and running the following command to add a Guest MLO SSID: > > ```auto > # Keep the original files for rollback. > [-f /root/wireless.before-guest-mlo] || > cp /etc/config/wireless /root/wireless.before-guest-mlo > [-f /root/mlo.before-guest-mlo] || > cp /etc/config/mlo /root/mlo.before-guest-mlo > > GUEST_MLO_SSID="$(uci -q get wireless.guest2g.ssid)-MLO" > GUEST_MLO_KEY="$(uci -q get wireless.guest2g.key)" > > # Generate four different local/unicast MAC addresses and avoid existing ones. > while :; do > TAIL5="$(hexdump -n 5 -e '5/1 ":%02X"' /dev/urandom)" > MAC2="02${TAIL5}" > MAC5="06${TAIL5}" > MAC6="0A${TAIL5}" > MLDMAC="0E${TAIL5}" > > uci show wireless | grep -qiE "$MAC2|$MAC5|$MAC6|$MLDMAC" || break > done > > # Remove only an existing manual Guest MLO configuration. > for SECTION in wlanmldguest2g wlanmldguest5g wlanmldguest6g mld1; do > uci -q delete wireless.$SECTION > done > uci -q delete mlo.mld1 > > uci -q batch <<'EOF' > set wireless.wlanmldguest2g=wifi-iface > set wireless.wlanmldguest2g.device='MT7990_1_1' > set wireless.wlanmldguest2g.network='guest' > set wireless.wlanmldguest2g.mode='ap' > set wireless.wlanmldguest2g.encryption='sae' > set wireless.wlanmldguest2g.wds='1' > set wireless.wlanmldguest2g.isolate='1' > set wireless.wlanmldguest2g.hidden='0' > set wireless.wlanmldguest2g.ifname='ra4' > set wireless.wlanmldguest2g.vifidx='5' > set wireless.wlanmldguest2g.ieee80211k='1' > set wireless.wlanmldguest2g.bss_transition='1' > set wireless.wlanmldguest2g.mld='mld1' > set wireless.wlanmldguest2g.guest='1' > set wireless.wlanmldguest2g.init='1' > set wireless.wlanmldguest2g.disabled='0' > > set wireless.wlanmldguest5g=wifi-iface > set wireless.wlanmldguest5g.device='MT7990_1_2' > set wireless.wlanmldguest5g.network='guest' > set wireless.wlanmldguest5g.mode='ap' > set wireless.wlanmldguest5g.encryption='sae' > set wireless.wlanmldguest5g.wds='1' > set wireless.wlanmldguest5g.isolate='1' > set wireless.wlanmldguest5g.hidden='0' > set wireless.wlanmldguest5g.ifname='rai4' > set wireless.wlanmldguest5g.vifidx='5' > set wireless.wlanmldguest5g.ieee80211k='1' > set wireless.wlanmldguest5g.bss_transition='1' > set wireless.wlanmldguest5g.mld='mld1' > set wireless.wlanmldguest5g.guest='1' > set wireless.wlanmldguest5g.init='1' > set wireless.wlanmldguest5g.disabled='0' > > set wireless.wlanmldguest6g=wifi-iface > set wireless.wlanmldguest6g.device='MT7990_1_3' > set wireless.wlanmldguest6g.network='guest' > set wireless.wlanmldguest6g.mode='ap' > set wireless.wlanmldguest6g.encryption='sae' > set wireless.wlanmldguest6g.sae_pwe='1' > set wireless.wlanmldguest6g.wds='1' > set wireless.wlanmldguest6g.isolate='1' > set wireless.wlanmldguest6g.hidden='0' > set wireless.wlanmldguest6g.ifname='rax4' > set wireless.wlanmldguest6g.vifidx='4' > set wireless.wlanmldguest6g.ieee80211k='1' > set wireless.wlanmldguest6g.bss_transition='1' > set wireless.wlanmldguest6g.mld='mld1' > set wireless.wlanmldguest6g.guest='1' > set wireless.wlanmldguest6g.init='1' > set wireless.wlanmldguest6g.disabled='0' > > set wireless.mld1=wifi-mld > set wireless.mld1.eht_t2lmnegosupport='1' > set wireless.mld1.mode='ap' > set wireless.mld1.encryption='sae' > set wireless.mld1.hidden='0' > set wireless.mld1.mldgroup='2' > set wireless.mld1.guest='1' > set wireless.mld1.isolate='1' > set wireless.mld1.disabled='0' > set wireless.mld1.init='1' > set wireless.mld1.iface='ra4 rai4 rax4' > > set mlo.mld1=wifi-mld > set mlo.mld1.disabled='0' > add_list mlo.mld1.bands='2g' > add_list mlo.mld1.bands='5g' > add_list mlo.mld1.bands='6g' > EOF > > # Apply the separate SSID, existing Guest password, and generated MACs. > for SECTION in wlanmldguest2g wlanmldguest5g wlanmldguest6g; do > uci set wireless.$SECTION.ssid="$GUEST_MLO_SSID" > uci set wireless.$SECTION.key="$GUEST_MLO_KEY" > done > > uci set wireless.wlanmldguest2g.macaddr="$MAC2" > uci set wireless.wlanmldguest5g.macaddr="$MAC5" > uci set wireless.wlanmldguest6g.macaddr="$MAC6" > > uci set wireless.mld1.ssid="$GUEST_MLO_SSID" > uci set wireless.mld1.key="$GUEST_MLO_KEY" > uci set wireless.mld1.mld_macaddr="$MLDMAC" > uci set mlo.mld1.mld_macaddr="$MLDMAC" > > uci commit wireless > uci commit mlo > > wifi reload > > ``` > > To restore the original configuration: > > ```auto > cp /root/wireless.before-guest-mlo /etc/config/wireless > cp /root/mlo.before-guest-mlo /etc/config/mlo > > wifi reload > > ``` Thank you for your understanding and support. ---

Thanks Charles - I can file that scrpit for future reference. I have since factory reset the router which did restore the WiFi, but recently something went wrong with AdGuard and Unbound - I determined I was unable to resolve any DNS when using AdGuard beta + Unbound. I have once again done a factory reset but this time I did not restore any setting from file and manually set up again. I am still using the AdGUard beta without Unbound for the time being - I will reinstall Unbound soon….
