Hi@Ger123 

If you are experiencing intermittent wireless connection on the range extender, please refer to the following suggestions:

1. Confirm the extender is properly located based on place your wireless Range Extender for optimal reception and performance.

2. Make sure the firmware on the extender is up-to-date.

3. Enable “High Speed” mode if you have a dual-band extender.

4. Disable Parental Control or Access Control (Blacklist/ Whitelist) on the host router if they have been enabled for the extender.

5. Turn off Band Steering (also called "Smart Connect" or "Whole-Home Wi-Fi") and set up different Wireless names for the router's 2.4Ghz and 5Ghz Wi-Fi.

6. Fix the wireless channels on the host router, such as channel 11 for 2.4GHz and channel 48 for 5GHz.

What if the Range Extender keeps losing connection?

  Thank you for your response @Joseph-TP 

About the question, the problem is not that the extender loses connection to the router, its that after an hour or so its impossible to connect to the extender itself! not even using an ethernet cable. All the connection lights are on on the extender.

1. it is properly located as stated in the manual

2. As I said in my post the frimware is up to date.

These dont make sense because the problem is that I cant access the extender, not that the extender has no connection.

3. Does not have “High Speed” mode

4. It is not on the blacklist of host router

5. I already changed 

6. Fix the wireless channels on the host router, such as channel 11 for 2.4GHz and channel 48 for 5GHz.
