me previous roaming issue may have been cause by the MAC address changing, causing the IP address to change, that how stock worked
everybody seems to be ignoring the issue with the ethernet speed
but you might have saved me some money here, If I don't need 802.11r I can still use my RE450 as the first point as I way going to buy a Multy M1 to run openwrt
That's not the point I was making... DFS is regulated by the FCC and other bodies who allocate spectrum because those frequencies are used by weather radar and some government/military services. As a result, there are likely other users on DFS.
I am not the one calling you stuipd... KISS has been used for decades as a term, and I use it even when discussing things with the smartest people I know.
Another new and significant snippet of previously secret information.
Did you know that almost all powerline devices have a passthrough socket for powering other devices?
I guess not.
And the weather radar satellite orbiting overhead, and who knows what else.
So no, you are not the only one using DFS channels.
You cannot reliably use a DFS channel for a point to point link.
Ofcom (The Office of Communications) is the UK equivalent of the FCC.
The use of DFS in wireless access points is very much included in UK regulation, as it is everywhere.
You have never had problems with stock on DFS, lucky, until suddenly, one day you will.
But then you have been complaining about the wireless link not working reliably.......
That will be me, because you steadfastly refuse to give the full information as well as not listen to what people say.
Sorry, but you are trying everyone's patience.
How are you testing this? From the internet to a device behind the Pi?
The Pi4 is a fine wired router, but the wireless chipset it uses is terrible and not suitable for this task. It is almost certainly the major bottleneck here.
You could install openspeedtest or iperf3 on your Pi and then run speed tests on ethernet and you should get good wired speeds.
Downstream wifi performance comes after that... it may or may not be that impressive, but those devices aren't exactly speed demons. It also depends on the configuration of the APs.
but still no I think the best solution is to forget 802.11r and just setup as a repeater but without WWAN as it blocks the connections between device on different access points
Maybe you should reset your two OpenWrt devices to defaults. Then make one of them a dumb AP and test that it works properly.
Once that's working as expected, set the second one up as either WDS or relayd. Note that performance will be roughly halved with WDS (I think for both APs). relayd may also slow down the performance, but only of the relayd configured unit.
WDS doesn't necessarily work well (or at all) between different vendors (in this case, the stock firmware on the 450 and OpenWrt on the others). relayd is probably the way to go here.
