Certainly sounds like the community could benefit greatly from your knowledge, if you care to share more about your set up and fixes I (and probably many others) would like to read about it. @groentjuh,
Same ssid for both 2.4ghz and 5ghz channel.
Clients can connect to the AP in different channel automatically according to the rssi and distance.
This function is called as ‘‘smart connect’’ in some asus routers.
MWan3 - causes some people problems, so a simple on/off button is more desirable than having to go into the guts of Luci.
IPV6 - yes, might be the future but is still very prone to leaking DNS (especially under Windows). So again, a simple on/off button (script) saves making a lot of editing when you upgrade firmware etc.
VPN Ping And Reconnect - many have reported that the VPN “hangs” even though saying “connected”. My bash script may be shitty but I am not a programmer and that was the best I could do.
No, I do not trust Google for DNS / anything important but I don’t mind pinging them (note: through the VPN, not using my ISP). If that is a bother then you can change 188.8.131.52 to something else!).
How to do this in luci? Just set the same ssid or any other options?
The design-as-I-say-it is like this: my mobile clients can connect to the 5ghz channel when I’m in the same room with the AP, and connect to the 2.4ghz channel when I’m in the other room. Once I come back to the AP’s room, the clients can also connect back to the 5ghz automatically.
Yup just set the same SSID and password for both. From a router perspective there is no difference than having them separated, all the magic happens at the clients. It’s up to their software to be smart and choose the right one. Older clients might just pick 2.4ghz each time even if 5ghz is stronger.
Thank you for your reply. I just test it with your advise. However, both my android phone (oneplus 5) and iphone 6s sticked to one channel and didn’t change to the other.
When I walked away from the AP, my phones sticked to the 5ghz. Only when the signal was almost disapear, then they changed to 2.4ghz. And when I walked back to the AP, my phones stick to the 2.4ghz and didn’t change to 5ghz channel.
By the way, I’m using the openwrt snapshot firmware
