Utter rubbish, I have been living near a military air base (for over three years and until tomorrow), they have 1001 different radar types, for my shitty consumer router to cause any interference it would have to transmit at 20 watts using the specific frequency needed and It would have to be within a specific range. Now, max 1Watt MAX transmit power is meaningless unless you live inside the radar housing. The organization that come up with these regulations are just clueless but there you are, be a good boy, dont break the law which is made for peasants to follow.

So, am I fine in using Channel 132?

FWIW - Radar Detection setting is set to Disable
Seems this might not make any difference.


At what point of time should one reset all configurations and set them again?
Could not doing this cause an issue if one has been updating to new versions every month or so?

Thanks

You can only avoid the passive scan respectively "No IR" by using non-DFS channels.

Or you have the know-how to change the drivers / firmware of your WLAN devices.

or reduce beacon interval on dfs ssids to speed up passive scanning detection, down to 50ms is ok with minimal throughput effect as most dfs channels (esp 100-144) are rarely used.

So, if DFS channels are not recommended to be used then what could be causing my speeds to drop off drastically on non-DFS channels?

Does anything jump out from the settings pics that I uploaded earlier?

Thanks,

To reiterate
132 has best speed, other channels get reduced speed, nearly 50%
Clients both windows and iOS take a long time to connect to 5GHz
iPhones etc keep dropping off wifi when they go to sleep and take a few seconds, sometimes a lot more to connect to 5GHz

A radar receiver needs to be quite sensitive in order to hear the return-echo from the object. Even a harmonic could be heard depending on the range of the radar unit and your distance from it.

Tbf, radar signals have a pattern to them and although you aren't likely to be recorded as an actual return-echo, you could overwhelm the receiver and block a weak return-echo.

That beacon interval=50 on 5GHz seems to have fixed the issue. I no longer am seeing LTE etc on iPhone when waking up from sleep. will keep monitoring but on Status->Sys Info I see Uptime of 22+ hours etc. for the iPhone. There was a power outage yesterday which explains 22+ hours but will see.

My 2.4GHz beacon interval=400 is unchanged. Should I change that as well?

Thanks

For Channel 132 being the best one for me following are Site and Channel surveys for 5GHz

Any suggestions/tweaks that anyone can think of?

Thanks

116+UU could also be good - who knows
just try it - I know that you do not ask for the first time Smile

There are no DFS channels on 2.4ghz you can leave it like that if you dont see issues on that band.

I see speeds of less than 25Mbps on Upload/Download on SpeedTest on 2.4GHz
I changed channel to 6 then 11 and speed is similar, a bit improved but not much.

For a 1-gig plan, that is just too low it seems.
All this time, I'd been using 5GHz on most devices and never looked at 2.4GHz speeds.

Does anyone see any other setting that I can tweak on 2.4GHz?

Settings screenshot is on the first page of this post.
Speedtest screenshots attached

Thanks,

thank you

I tried that and it seems to be working better than 132.

I keep asking because you never know when someone looks at the settings and something clicks,, Razz

You can operate 2.4Ghz also with 40Mhz channel width.

higher channel width = more bandwidth

The 2,4Ghz band has only space for 2 interference free 40mhz channels (in the USA only for 1 channel).

And if you live in an apartment block with many other AP your biggest problem will be interference.

Under good conditions with a good client, 2.4Ghz can be fast enough.

I have with a 4x4 client ~350Mbit
