So I was in the process of doing an upgrade on my TP AC-1750 and the power went out. Now the only thing that turns on is the Green power light. Thats it. I have tried to unbrick the device using TFTPD, went through all the A7 firmwares from the TP site, nothing. Tried the WRT upgrade, then the Factory... nothing. Am I screwed or is there a possibility that is can still be fixed? Please help. Thanks.

This is generally a good sign.
What was the original (exact) filename of the recovery file referenced here?
Thanks. I tried AGAIN just a little bit ago and it flashed... Im having other issues now, not sire if I should start a new thread or continue here? 5GHZ radio is working. The 2GHZ is not transmitting at all. Bitrate is ? and I cannot find the SSID on any device I have. It worked before these problems. Need help with that. Thanks.

So I reflashed the firmware through TFTPD and 2hgz showed working on router and wifi AP list. Pulled power, plugged it into gateway, and it dropped again... what is going on?? Thx
Did you change settings for the wifi (aside from setting the country code, SSID, encryption type, passphrase, and enabling wifi)?
No, after the flash the settings were all the same. I just noticed that the 2ghz was working. Disconnected and relocated, powered up, and nothing. Im trying to reflash it now as we speak.
Ok, so I plug it into the computer, and I notice that 2GHZ channel is showing, but not the 5GHZ. Unplug from computer and its the opposite... correction, 5GHZ showed up... this is weird. Is it a distance thing?
I can't explain that behavior... it doesn't make a lot of sense.
Let's see the network and wireless config files.
But it could be a failing power supply. With any luck, the power brick is the problem -- do you have a similarly spec'd (ideally higher current capacity) power adapter you can try?
We need you to look and confirm the version.
This has got to stop. Please just follow @psherman 's lead.
Please snip both the interface page, just the red and green rectangles; don't need the stats and please snip wireless page redact any personal information.
I put 5 and 2 next to the SSIDs...
Ok so I still have the router by my computer, unplugged ethernet and restarted.
Ok, so i walk it over, plug in the gateway, and power and its back to only transmitting 5g...
No one asked you to do that.
Please show me the interface page and the wireless page.
OK, thanks. On a side note, before I get the info, the router green lights show both 5 and 2 GHZ...
Version 5.8
The SSIDs were already like that... anyways, the interface page that shows lan and wan? Thanks for the help.
Are you using the same power adapter in both cases?
Yes it is the same adapter.
That is correct and the wireless is one tab down.
Please post the config files requested earlier.
