Status page added.
Bandwidth graph page added showing tiny graphs.
After I upgraded to the r50551 build, I found a couple of oddities. I had been running the r50500 build before this.
The bandwidth graphs on Status->Bandwidth got a LOT smaller. They are quite a bit harder to read.
VHT160 disappeared from the 5Ghz wireless settings. And I can't seem to get VHT80+80 to actually work. I was using VHT160 with no problems and I had successfully tried VHT80+80 before. I had to select VHT80 to get it working at all. VHT80 has a data transfer rate quite a bit slower than I am used to. I couldn't get a screenshot showing the option missing. Every time I grabbed the screenshot, the dropdown would close before it actually snapped the image.
If I can gather some more information to help troubleshoot, please let me know.
Trac SVN (Bugtracker) Ticket #7601: webUI bandwidth graph has been reported and fixed two days ago (r50559).
VHT160 is strange I can replicate the issue on R7800 with same QCA9984 radios. Would ignore 80+80 it's useless.
VHT80 4x4 is same data rate as VHT160 2x2, if clients support 4x4 should be same if not better, 800 to 950 Mbps.
Country? Advanced Settings: Domain UNITED_STATES to PUERTO_RICO, Save, a Channel Width VHT160 appears.
I don't see build 50559 on betas yet. I'm beginning to look into how to build it myself.
Interesting that changing the country to Puerto Rico brings back VHT160. I would think this is a bug, but I'm not an expert on what the FCC allows.
Now I have a nice wide radio footprint. Nobody ever seems to use the middle frequency ranges of 5Ghz. They are all packed into the lower or upper range.
I have never seen anything in the UI talking about 2x2 or 4x4, so I don't know what to do with that info.
The instructions for building DD-WRT are not working for me. I can't seem to read between the lines to figure out what actually needs to happen to get it all working. One problem is that the directory in the toolchains tarball that it says to add to the PATH does not exist.

@elyograd as you may already know 2x2 3x3 4x4 are the number of bandwidth streams a device is capable of per implementation. The UI doesn't say anything about this in any way. TBH I dont even think its worth it as would only show the routers available per implementation how helpful is this? Not very IMO because the clients are unlikely that e.g. mobile phones owners know what their devices are capable of anyway or any other client device.
Likely a very small subset of regular users would know, developers and researchers would know, the information is, out -- there
So the 4 spatial streams are displayed in the GUI, better said the chain info
You just have to move the mouse pointer over the MAC address of the client and the 4 antennas of the router are displayed.
It is also possible to display the clients info in the console.
There you can also see the spatial streams that the clients support.
The bitrate of the clients displayed in the GUI in combination with the channel width also gives information about how many spatial streams are supported by the client. (e.g. a RX/TX rate of 866Mbit with 80Mhz channel width can only be 2x2).
So you could also display this information in the GUI, but it is not necessary.
The conclusions can be drawn already alone on the basis of the bitrate.
And the users who can do something with the information also know how to get it.
It is difficult with smartphones, even if they have a Qualcomm SoC, they can use a different WLAN module, e.g. from Broadcom.
You have to look at teardowns, etc., and modules from Murata and Co. usually appear.
Qualcomm SoC ≠ Qualcomm Wifi
But no matter the very most devices have only 1 or 2 antennas with the exception of a few MacBooks Pro with 3 antennas and 4 antennas have in principle only routers or expensive wireless cards that you have to buy individually.
Antennas need power and that's why you won't find a 3x3 or 4x4 configuration in mobile devices.
That would reduce the battery life and neither customers nor manufacturers want that.

Yep I dont even check what my laptops are able todo, its meaningless when the speeds are more than adequate for my needs. Not even while performing pen testing I cared about this.
