5ghz randomly stopped working/showing on extender.
I have a TP - Link ac1200 wifi range extender re355. The 5ghz mode has always worked on this extender but now it has randomly stopped last night and i have tried resetting the extender, modem, and changed the frequency channels. Someone please help.

@Daniellucas issues like this can be caused by many factors, Such as power outages, power surges, issues with the router or issues with the range extender itself. The 1st step in troubleshooting this would be to power cycle the device by unplugging for 30 seconds and then reconnecting it and seeing if it restores service on that band. If not the next step would be to check if you are on the latest frimware. for the RE355 our latest frimware is: https://static.tp-link.com/2018/201803/20180307/RE355_V1_180204.zip. Once updated then test again. if still down the next step is to hard reset the device and run through the setup again. during this step its important to see if the default name is showing for the 5GHz band and if you can connect and access it. If you are able to then this indicates the issue is located on the 5GHz band of the router, which could be channel or channel width related or require more troubleshooting with the router's maker.
Let us know if this helps

Hey @Carl , thank you so much for the quick response. I have tried all your steps and updated my firmware. Unfortunately, there still is no sign of a 5ghz connection. Here is a screenshot of what the repeater website is showing: http://prntscr.com/lwa4tl http://prntscr.com/lwa7e2 http://prntscr.com/lwa7l5. It states that the host networks 5ghz channel is no signal. http://prntscr.com/lwa7wy This screenshot shows my current 5ghz channel configurations. I dont know what else to change or do to make the channel appear to have a signal on my extender.

@Daniellucas Thank you for the screen shots. So I have a few more questions with this infromation.
1. When you defaulted the RE where you able to connect to the default 5GHz band and log into the RE's UI page?
2. If so were you able to successfully configure the RE?
If you were it would appear there is possibly an issue in the signal reaching the RE. This can sometimes happen if another network is close and operating on the same channel creating interference. This interference can cause a single to be reduced even though it onced worked. A few things I would change on your router.
1. The bandwidth. Change it to 40MHz or 20MHz. the best way to describe what this does is a Mag Lite Flashlight. 80 is when the flashlight head is twisted loose and although it covers a bigger area the light is dimmer and doesn't go as far. As you tighten the head the beam gets brighter and more narrow, providing a stronger beam further away. The smaller the MHz the more narrow and more powerful the single but it doesn't cover as great of an area.
2. The channel. I would recommend shifting the channel to the upper level chanels like Change 153 just to see if it helps.
Beyond this I would update your router's Firmware if not already done. If there is still an issue we can replace as long as the unit is still under warranty, as there is always a possiblity the unit simply went bad. Let me know how the above test goes and we can go on from there.

@Carl Thank you so much! Changing the frequency and channel did the trick. There was a past article on the issue and it stated to keep the channel frequency around 36-48 so that is why i had it down there. Thank you again!

I only have a number that can be used for US customers. Based on your regestration location you are in Spain. As support is regionalized you would need to https://www.tp-link.com/es/support/contact-technical-support/#LiveChat-Support for your region's methods of contacting a live agent.

thank you.
I ran into this problem just by upgrading my router. And thanks to the info above was able to change bandwidth/channels to get 5ghz working again.
Nice product.
