Model: RE505X  
Hardware Version: V2
Firmware Version: RE505X(UK)_V2_1.2.12 Build 20260402. Published Date: 2026-06-12

The recent firmware update for the RE505x V2 appears to be broken. After updating to the new firmware no devices could connect - so no app or web page login possible - to the extender and a factory reset was needed. After configuring the extender after the factory reset and client devices able to connect again if the extender is power cycled no client devices can subsequently connect. The SSID is visible but a connection is never achieved - this is for all previously connected devices - just forever cycling attempting to connect. The extender is configured 5gz to router connection, 2.4g extended network only. I can see from the router the extender is connected over 5g but the 2.4g of the extender is visible but never accepts a connection. Only a factory reset of the extender resolves it until it is power cycled and the problem returns.

Hello @MrChips ,

Welcome to our community.

 

Please change your router's wireless settings as follows:
1. Change the channel to 44.
2. If the router's Encryption is TKIP, change it to AES.

 

If it is a TP-Link router, you can refer to How to change wireless settings on TP-Link Wireless Router.

Thanks for the reply. My router is AES but channel 36 for its 5 ghz WiFi. However the tplink extender is connected to my router without issue - I can see that from my router's list of connected devices - it's the tplink extender which won't allow connections after a power cycle on its 2.4ghz WiFi.
