Hello, I received my brand new C5400 router a few days ago. When I first hooked it up, everything seems to be working fine with stock firmware 160927. Then I upgraded the firmware to 170630 after a couple hours use. Suddenly the two 5GHz band wouldn't work. At the quick setup page, they were greyed out, and at the bottom of the web GUI, it says: the 5ghz network is unavailable due to restrictions in your region/country.
I have tried to reset the router to factory default (several times), also tried to re-apply the firmware update again, neither helped. Also, even thought the MU MIMO option was not selected, under the Advanced/wireless setup section, it always shows "you must have devices support this feature ....". It seems somehow the router was permanently "written" during the firmware upgrade, and user can't apply certain settings.
I believe there are still bugs to be worked out, especially with hardware version V2 and firmware verion 170630.
Hopefully TP LINK will address this issue ASAP. Thanks.

I asked tech support if there was any need to update from 1.0.9 Build 20170406 rel.53986(5553). They responded:
Thank you for reaching out to us regarding your router.
[/FONT]
[FONT=Arial]The update to the current version is a feature update, the newest version being a bug fix for the prior feature update but would not affect the version you are on. If you have no interest in the Homecare features there is no reason to upgrade at this time. I have linked the new feature overview below:

Got my replacement! :) Set up and working like it should. I will not up date the firmware! Came with 1.0.5 Build 20160927 Rel. 53959(5553) V2
Well, check this out people,
The 2nd day with my replacement running original firmware I encountered an issue, both my consoles (PS4 & XBOX 1S) loss LAN connection. The XBOX 1S froze ....PS4 just indicated there was no LAN cable connected. After I did a hard shutdown of the XBOX it also indicated there was no LAN cable connected......So, I Updated the firmware from 20160927 to 20170406, after that I could not get into the UI Admin page to configure the router. Eventually I did and decided to upgrade to the 20170630 firmware. Afterwards it started rebooting. I waited a day and was able to get connected, upon connection I was greeted with an update, so I clicked and let the system update to the latest firmware. After that only the power light was lit. LOL! Trouble shot with support over the phone afterwards it was determined a replacement is needed and is processing at this time. The good news is that they are gonna upgrade my replacement to the Talon AD7200!;)

hai.. i bought mine 2 month ago twice my ac5400 reset itself. Today is the second episode. During my setup one of the band was not available for malaysia (5G-1). It is possible the router auto reset it self and the 5G-1 not allowed in Malaysia.
Thanks
Hi , how about your ac5400 now ? my ac5400 same 5G problem in malaysia

I got a similar problem, and it even falls into a state that only one 5GHz wifi can be found.

I bought a C5400 V2 last week and got it all hooked up yesterday. My 2.4 Ghz band down 130 up 100. My 5Ghz-2 band down 700 up 100. My 5Ghz-1 band down 0.26 up 0.14. And that is with the new laptop next to the router. As well as the 5Ghz-1 being so slow, it takes about 3 minutes for the lap top to connect to the router. As for my Galaxy S9, works great on 5Ghz-2 but wont connect to 5Ghz-1. Have spoken to tech support who got me to alter a couple of setting, then she gave me some speil about it might take 24hrs for the change in settings to take effect. I'm running out of patients fast. Might be returning it to where I purchased it if not resolved quickly. I am extremely disappointed with the product and the service so far!
