    I am the OP. I had the problem with 2 new C5400. I got it from Amazon it had the problem, I exchanged it with the same model. Had the same problem.

    I had the RMA created for this one. Not holding my breath, IMHO this is a firmware problem and not a hardware problem.

    Cool My Resolution

    Hi. I solved a similar problem with my Archer5400. I changed the channel to always use channel 4. Here's how I got there...

    It was working for almost a year and then one day my 2.4 was gone. The 5 still worked (both of them), but the 2.4 was completely non-existent. I reset the router to factory defaults and 2.4 showed up. Then I did a restore to my settings and it disappeared again. So I reset to factory defaults again. The 2.4 showed up. So I just changed the SSID name to match what it had been and switched it from Auto channel to Channel 9 (which I had been using because it has less interference in my area). I went to go see if my thermostat had connected and it didn't see the 2.4 again. I went back and checked and the 2.4 was gone again. I tried changing to channel 11 and it still wouldn't show up. I finally switched it to channel 4 and it worked! It's almost like the router isn't transmitting the higher channel numbers for some reason. I don't know if this will help anyone else, but I figured since it worked for me, maybe it would for someone else.

    Good luck!

    Yeah When I get my RMA I think I'm just going to put the oldest firmware I can find or maybe try a third party one

    I set the channel to fixed and still got the problem.

    Well I got the New RMA router. Hooked it up. Worked great for about 12 hours. Then the whole thing went dead and no device had internet wired/wireless. Couldn't even login to the admin page to see what was going on. Tried to reset it. Still did the same thing. The LED's made it seem like it was stuck in a reboot loop. So I'm returning that one and I'm done with TP-Link. Going w/ Netgear for now on

    That is crap!!

    I got here on the same reason as you.
    I have a smarthome soulution that runs many devices on 2,4ghz. My SCREENS\door sensors\Garage port opener and alot more...
    And now I cant use my house anymore as the 2,4ghz is failing often!!

    there is NO SUPPORT!!
    And I have been to the store for a return, they only fill out a form and send it in the TP-LINK waiting for a reply that takes forever.

    WHY IS THERE NO UPDATE ???


    btw, I did update my router some weeks ago, but that only made it worse.
    It`s almost impossibel to LOGIN into the Router because it`s so slow. I often need to reboot router manually.

    Same exact thing happened here. Do the smart thing and stick w/ a more trusted brand like netgear/Linksys. I picked up a Netgear X6 has been running strong. Return the TP-Link and don't waste anymore time w/ it.

    2 RMA's from TP-Link still has the same problem and no firmware update after 2 months.

    I see from the V1 latest firmware release note "Fixed the bug that SSID may disappear after working for some days", Same problem is happening for V2 on the 2.4 ghz. Can someone from TP-Link take a look at this.

    I think you need to send your issue directly to the support for further troubleshooting now.

    Having a similar issue where I can see the 2.4 GHz network but it has not internet connection. I reset everything back to factory settings and it is still intermittent along with no longer being able to see my 5G_1 channel but the 5G_2 channel is available and working properly.

    Same Issue WIth 2.4 GHZ Radio

    Same here, with the 2.4GHZ radio issue. I spent hours triaging the issue prior to contacting TP-Link support, with no resolution. Finally received an RMA after several email exchanges. A replacement was sent for my C5400 router and I also paid for 2 day expedited shipping. I received a refurbished router and it has a loose part rattling around inside the case. I noticed this before I opened the plastic bag the router was packaged in. Took it out of the bag to see if the lose part or whatever it is would come out through one of the many vent holes. Nothing. Still have the part rattling around making a metallic sound.

    I fear that if I put power to this refurbished router that it will be a safety hazard as the loose part could cause a short resulting in a fire. Reported a new case through the online support request and requested a "new" router and my 2 day shipping fee refunded. I received an email from support without a resolution or RMA.

    So I'm spending more time trying to get a new RMA for the replacement sent for the original RMA. All I received is an email saying they use refurbished units as replacements. No RMA has been assigned to this yet.

    I'll be back to report the outcome. Sure wish I researched this brand and model more prior to purchase. If I had seen this thread I would have purchased another brand.

    Anyone know how to escalate and support issue?

    This will be my first and last Archer TP-Link product.

    I cannot believe this is a sticky thread and the manufacturer is doing nothing to resolve.
