CPE510 as Access point - Wifi crashing when connecting
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hi all,
I have just bought and installed a CPE510 to use it as access point for my garden, where the home wifi doesn't reach properly.
It is connected and working, I have set up the wifi SSID, I have reduced the transmission power to 10dBm since the garnen isn't too big and I can see that the power on the receiver is reasonable (I have been reading of issue at short range due to saturation of the receiver, and I have followed the advices), but I am having some odd issue.
If I connect the PC, everything is fine. Fast and stable connection, no issue. But for that, I had to select MCS7 -I couldn't find any information about the compatibility of my wifi on the computer, and this one seems the highest that allows me to connect.
When I try to connect the mobile phone (Android 9, nothing fancy), the phone remains for a few second trying to connect, then it tells me that it is not able to connect to the network. At that point, it doesn't see the network any more for a couple of minutes at least. Now, what is even more odd, the other devices connected to the CPE510 get also disconnected and can't see the network for the same time. And, even if they see it, they can't connect.
So, it looks like that attempting to connect the phone is crashing the access point, for some reason that I cannot understand. Security doesn't make any difference, I get the same behaviour with both no security or WPA-PSK, WPA1 or WPA2.
My settings are
802.11a/n
20/40MHz
MCS7
Channel 100
TX power 10dBm
MAXtrem disabled
Security WPA-PSK
WPA2
Encryption auto
From the status, everything looks ok. No entry in the system log.
Another strange thing: this is my Firmware Version:
2.2.1 Build 20190417 Rel. 34231 (4555)
When I checked on the website, this is indicated as latest one:
CPE510(UN)_3.0-up-ver2-2-0-P9[20190125-rel36276]
Is it normal? Version is lower, release is higher?
Thank you for any help you can provide!

@LightflowMark well I can't say I'm happy to see that I'm not alone, but for sure it's a relief to see that the problem can be reproduced...
Have you tried to report the issue to TP Link? I admit I did it only now, I never had the chance to do it at the time and then... I forgot

i am having the same issue. i spent 4 weeks replaced 3 devices now i have CPE510 V3.2 and V3.0 with the latests firmware 2.2.2. i did try 4 diffrent firmware versions on both devices and its always the same issue. As soon as 2nd or 3rd wifi device joins the network the coneectivity is lost for all. i am using the CPE in AP Client Router mode and my work around was to connect CPE210 to serve as access point but this foot print and aditenal device and cables are not what i was looking for. This is a majot bug and i think what someone said before about the new device trying to negotiate channels with the CPE is what trugger the issue. the CPE should be able to maintain many connecions and all explanations about this is not an AP are not relevant. this does not work as advertised please fix it.
