Officially, there are three bands :
1)U-NII-1 = 36-50
2)U-NII-2A = 50-64 U-NII-2C = 100-144
3)U-NII-3 = 149-165

We all know U-NII-1 is universally available.

TM firmware is using BS country code with extra parameter "no_autodetect": true which results in channel 36, 40, 44, 48, 100, 120, 161 and 165
However, simply forcing BS code without this extra parameter results in channel 36, 40, 44, 48.
I guess one must write extra parameter into config.bin for the firmware to display additional higher channel. I assume "no_autodetect": true actually disable DFS.

No idea how this parameter should be written into config.bin
To be certain, I need config.bin with channel 100 from TM router. Anyone with TM latest firmware can donate a config.bin for me to check?


Forcing MY country code will result in channel 36, 38, 40, 44, 48, 149, 153, 157 and 161.

Here is a funny stuff, if one forces TW code, one will have access to U-NII-2A channel (auto default to channel 56), with the side effect 2.4ghz wifi stops working . From what I can see, TW code will force DFS to be enabled regardless of the extra "no_autodetect": true parameter Something about 5ghz DFS causes 2.4ghz wifi to stop working.
The same 2.4ghzs issue also happens with SG country code.


EDIT:
Weird, I am expecting higher channel with higher transmit power should produce better signalquality . But the result kinda...strange:
36 = -44dBm
161 = -52dBm
(The closer to 0dBm, the better the signal)
As if the higher channel still transmit at same power as lower channel.


EDIT:
Would be grateful if someone help me to test these countries code:
DZ
AL
BH
KW
AZ
EG
UA
IN
SV
CO
CR
PE
AR
MX
CA
KR
JP

The above is the one I haven't test yet. It took me too long to test, I already tested 80+ country codes.
Some country code broadcast at higher power.
Just write out 5ghz range for each of the country code above.

edit:
after searching high and low for BCM47189 documentation......it appears C1200 V1 EU doesn't support DFS. This confirms my suspicion about TM Bahamas region code with additional parameter.......

im using wireless. whats the best wireless usb adapter for unifi?

came across tplink t4u. anyone using it? how's the performance?

Firmware Version : 1.0.0 Build 20180208 rel.57928 (EU)
Hardware Version : Archer C1200 v1.0

Recently just updated to the latest firmware version, the dynamic dns it fail to update.
How to solve it?

I assume you get your dynamic dns detail correct....

Please read the following.
http://forum.tp-link.com/showthread.php?10...ll=1#post225389

Fair enough.

I was looking at the local TP-Link site, which I don't think they've updated to the latest V4 version of the Archer C7.

See the Australia TP-Link site for a quick overview of the C7 v 4: https://www.tp-link.com/au/products/details..._Archer-C7.html

just curious, actually what is the difference between TM supplied C1200 v1 compare to C1200 v1 sold at Malaysia market?

do Marketed unit have this self reboot issue?

I've perused the US site - different antenna diagram, but same conclusion - TP-Link US - Archer C7

Hi all.
Who has reboot issue try to change your power adapter.
Try to use 2A or 2,5A power adapter instead of 1A power adapter.
Maybe reboot issue will be gone.
Power adapter is not expensive.

21 days uptime now... memory usage suddenly drop from 50% to 42% . CPU maintain 20-60% .

Exactly the same hardware inside/out with same issue.
You still have your C1200 v1 with EU firmware?
Can you send your backup config.bin to me privately?
I want test something.



No difference.

c1200 is really hopeless

Tested, same problem occurred.
Also cool it down with fan, same problem occurred.
Best solution is get other wireless router.

Can you reset your router, set some random wifi password and pppoe password, save.....then go to advanced, system tools, backup&restore, backup and send the copy of config.bin to me?

And TP-link don't seems to be doing much to remedy the problem, wondering why.

Okay.....check your PM inbox.
Report back the result....

thanx..can you tell what did you enhanced?

Hopefully extra 5ghz channels appear?

ok thank you very much. What about 2.4Ghz wifi power 200mW max for malaysia like the unifi stock firmware?

the australia firmware wifi power for 2.4G/5G is very weak compared to unifi firmware
