【Resloved】RE450 V3/RE455 v1 weak security issue
I have followed the following steps for my Hardware version RE450 v3.0
Downloaded firmware update from https://www.tp-link.com/uk/support/download/re450/v3/#Firmware
Used ethernet connection direct to RE450 extender
Updated firmware using this package re450v3_un-up-ver1-0-2-P1[20201203-rel80349] (as downloaded)
Used the reset button on the device
Used the reboot button on the interface
This is the firmware version reported from the management interface: 1.0.2 Build 20201203 Rel. 80349(6985/8575)
YET I am STILL getting the weak security issue on my iOS / iPadOS devices
To ease troubleshooting, I have labelled the two extender SSIDs with _EXT2 and _EXT5 (to further separate 2.4ghz and 5ghz)
From the Mac terminal ./airport -s command you can see the output below.
Clearly, it seems that as of this firmware update, the 2.4ghz extended network is no longer including TKIP. But, the 5ghz network is still giving TKIP.
| SSID | BSSID | RSSI | CHANNEL | HT | CC | SECURITY (auth/unicast/group) |
| Host | 80:72:15:6c:8e:b2 | -73 | 6 | Y | -- | WPA2(PSK/AES/AES) |
| Host_EXT2 | d8:07:b6:dd:fe:58 | -48 | 6 | Y | -- | WPA2(PSK/AES/AES) |
| Host_EXT5 | d8:07:b6:dd:fe:59 | -55 | 36 | Y | -- | WPA2(PSK/AES,TKIP/TKIP) |
| Host | 80:72:15:6c:8e:b5 | -64 | 36 | Y | GB | WPA2(PSK/AES/AES) |
I have attached the Host Network and Extended Network settings screens for reference also.
Please can you advise if this can be fixed in the next 28 days, otherwise I will return the kit as defective where I bought it.
Side note, it would be more helpful if you gave the user the choice of security encryption so that we can forcibly disable TKIP. I have no devices reliant on this legacy encryption. Inclined to return just based on this issue.
