Exactly the same with my Archer C6, updated to the last FW version. 2.4ghz is extremely unstable, I have to restart the router every few hours. Tied changing the channel, the power, disabling 5ghz. Nothing helped.

Hi Kevin,

 

Thank you for your reply.

 

Your colegues in UAE seam to have been infected by the Spanish virus, not the Covid but instead the "Sleeping nap" virus after lunch that is quite commom in spain during the summer months. The problem is that here in UAE we are in the desert and summer is all year.

 

First of all, no problem with the firmware upgade at all. that was sucessfull. By the way, i have an UPS supporting my critical systems including the router, NAS and others.

 

When i purshased the Router he came with the very first firmware release, and only after a few montha later i noticed it and upgraded it.

So. in the first few months the router worked just fine with all 3 ssid's fullu functional (ome 2.4Ghz ssid and two 5Ghz ssid's).

 

Them a few month back i noticed that the firmware was alreadu 5 years old and decided to upgrade it (simple as pressing a button).

At beguining i didnt noticed that my 2.4Ghz ssid have disapeard, but with time i started noticing that my RE650 network exthender 2.4Ghz LED was not on which caught my attention specially because my extended network started to become too slow and even irregular.

 

Another reazon that led me to pay more attention to the router configuration was because now i'm working from home for more than 6 months and i had to open a guest 2.4Ghz network in order not to mix my home netwrok with my work network. Now that im more time at home and the network is more need de I was paying more attention to the devices that i have at home which are connected to my router (wired and wireles).

One device which i notived stoped working was ny CromeCast connected to my TV, because it was linked with my 2.4Ghz ssid.

 

Answering your questions, i already performed a configuration backup, then factory reset the router, and then restored the backup, but nothing my home 2.4Ghz ssid does not show on all my devices (even the ones in the same room as the router). The LED in on on the router, and its not a problem of the devices because they are able to see my RE650 2.4Ghz ssid.

 

Tying to change the 2.4Ghz ssid channel is not possible because that option is not accessible (i can share pictures).

 

Kind regards,

Joao Vaz Martins

@Kevin_Z Kevin, you look like a robot.

 

Can you get us something?

 

You didn't helped anyone on this thread yet.

To whom it may concern and all those affected by this manufactures equipment:

 

Archer CR700

Hardware Version v1.1

Firmware: 1.1.0 Build 20170314 Rel 542320

 

    I dealt with this issue about 8-10 months ago, and had purchase a different brand router because I was tired of the the dropped channel, the replacement die the other day and in a pinch I went back to the Archer CR700, having forgot abbot this issue! I had a chat with Tech support today and was given the same fix as many dealing with the 2.4Ghz channel dropping out. I explained that their is not wrong with the wired connections and nothing wrong with the 5Ghz or for that matter, everything else on the modem/router works perfectly, except the 2.4Ghz channel. What this says to me is that who ever TP-Link purchase their chips/tech from let them down. This is obviously not an issue that is experienced by One user, one device according the the multiple posting's with different models.

  I've tried the suggested fix, by changing options (Channel and Bandwidth), it has failed three times since then. I'm done. 

 

      THIS IS THE LAST TP-LINK DEVICE I WILL EVER PURCHASE, MY FRIENDS WILL ALSO KNOW OF MY EXPERIENCE WITH THIS MANUFACTURE. IF THEY WON'T STAND BEHIND THEIR PRODUCT, THEN THERE IS NO REASON THEY NEED MY RETURN BUSINESS!!!

 

Later TP-Link
