@DISC-part.3 Can you please attach a screenshot? We just want to help you and ensure you haven't made a mistake. Such claim de-rails our pressure for a faster resolution on this important issue.

If we can prove that your device is working correctly, we maybe able to get a warranty replacement. Uploading a screenshot (similar to the ones I uploaded) will really help us. Thanks in advance for helping us out.

@DISC-part.3 Thank you. You're right. Apologies for doubting you, but I found it hard to believe what you were saying! 

I've tried everything - did factory reset multiple times and re-configured using different browsers. I even downloaded the published firmware from the website and applied it (which actually downgraded my firmware from 1.0.1 back to 1.0.0 but nothing really has changed. The only material difference between your situation and mine seems to be that you got a V2 and I got a V3.

@Solla-topee We're looking for your input here. Is this issue only with V3? What are customers with V3 supposed to do in order to get their extenders working as expected? Right now it's broadcasting in TKIP and to me, that's a defect in the product which you must address as part of warranty support. So, please respond and address our issue.  

@Solla-topee 

Any update for those who own RE200 and are facing the same issue?

KR

@Solla-topee Thank you for understanding our pain point, and prioritizing the issue. 

On the other thread, you offered a beta firmware to RE650 users. When you have a beta firmware for RE450, please feel free to send it to me. I will gladly help with testing and providing feedback. 

By the way, there is also this other issue that intermittently happens, when my iPhone or Macbook Pro is connected to the extender. The internet connectivity stops for no reason but I still have access to the intranet (I can access other devices on my home-network sharing the same wifi). Some times this fixes itself when I switch to the host network, and then switch back to the extended network. Sometimes, I'll have to turn off wifi and turn it on again. I am not sure why this happens. Do you think this is also somehow related to TKIP, or is this a different issue?  

@Solla-topee Another question.

Will the updated firmware also address the issue of having to fix the 5ghz channel to band 1 only as per https://www.tp-link.com/in/support/faq/1314/

According to me, this is an issue. Since Oct 2018, Government of India allowed the use of large swaths of 5 Ghz spectrum to be used indoors without license. See "License Exemption in 5 GHz GSR 1048|E| dated 22/10/2018" - https://dot.gov.in/sites/default/files/License%20Exemption%20in%205%20GHz%20G_S_R_1048%28E%29%20dated%2022nd%20October%2C%202018_0.pdf?download=1

"No licence shall be required under indoor and outdoor environment to establish, maintain, work, possess or deal in any wireless equipment for the purpose of low power wireless access systems, including radio local area networks operating in the frequency band 5 150-5 250 MHz; 5 250-5 350 MHz; 5 470-5 725 MHz; and 5 725-5 875 MHz..."

Many routers are using the spectrum, finding a free channel in the "auto" mode and broadcasting in that channel. But TP-Link doesn't work on any of those channels. So, we invariably have to change channel in order to get the 5 Ghz bands working. But that poses multiple problems:

1. Non-technical customers do not understand why it is not working, and it's difficult to give instructions that work for every router. I've been reviewing new questions on this forum, and interestlingly, half of the questions are about 5ghz spectrum. And in your documentation, you blame the DFS function? 
2. Some ISPs lock the channel selection in Auto. My ISP is one such example. I had to make multiple phone calls to get to the correct engineer who understand what the issue is
3. Some ISPs do not agree to change of channel selection from "auto" - and customers are left with no choice but to return your extender or to live with the problem
4. Changing the channel to 36, 40 etc. can cause interference because those channels are croweded by other routers in the apartment building, causing connectivity issues or low spped. That is where DFS is of critical importance and that is why our routers offer it. And TP-Link is crazy enough to ask us to switch off DFS. 
5. If the router is reset for whatever reason, the channel selection goes back to "Auto". The router picks channel 149 and then the extender doesn't work. And then we have to follow up with our ISP to set the channel back to 36 or 40.

I KNOW you understand that this is an issue because you spend half of your time trying to help your customers set the channel to 36. I know how you feel. 

The only thing that's keeping TP-Link going in the Indian market is the high variety and low price of your equipment. TP-Link pays youtube influencers, so you get good reviews and awards. But the truth is that your equipment is riddled with very fundamental issues that cause poor customer satisfaction. 

@Solla-topee Waiting for your response. 

@Solla-topee 
 

I upgraded the firmware on my 3 RE450 V2 extenders to the latest version (1.0.5 Build 20200914 Rel. 34203) tonight and am still seeing the message on my iPhone (IOS 14.1) indicating weak security. 
 

Was this not supposed to have been resolved in the updated firmware?

Also, is it possible that the Tether app is causing the configuration to be reset? I think someone on this thread mentioned that as well I thought that after I upgraded the firmware I had stopped seeing the weak security message but then after checking the devices on Tethers it seemed to com back. 

I just purchased these 3 extenders, so if I can't resolve this ASAP, I'll be returning all 3 to Amazon. 

screen shots included:

Hi @Solla-topee, do you have a rough ETA for the RE450 V3 firmware that addresses the TKIP issue? Will it take 2 weeks? 1 month? I really need the wifi extender working in my house so that my family gets a good network in the entire house, but I am unable to use it now because I can't enable AES. Unfortunately, Amazon in India doesn't accept returns, so i am stuck with this faulty device, and I am now wondering what to do.

If the firmware is going to take months, then I will have to abandon this extender and buy a different one from a different brand and stop bothering you. If the new firmware will be released in just just 1-2 weeks from now, I will wait. 

Please help me with this decision.
