My RBR850 has an unstable guest network

My RBR850 has an unstable guest network.

The firmware is V7.2.8.2. In addition to the router, I also have 3 satellites.

The firmware updates automatically, however, I see version v.7.2.8.5 on the internet.

I have performed the update on the RBR850 but cannot update the RBS850.

Could this resolve the unstable guest network?

Or is there something else going on?

 

My regular network works just fine.

    Was the Guest WiFi network unstable before the router firmware was updated?

    Getting all of the units on the same firmware release (either the previous version or the latest version) is definitely worth achieving.

    It might be useful to understand what you mean by "unstable".

    You need to update the RBS first, then RBR lastly. RBR and RBS needs to be on same FW verison. Probably why guest network maybe problematic.
    Besure your applying the RBS CHK file to the RBS web page to update them.

     

     Follow this guide to help you get the system updated:

    Recommend doing a full on factory reset and setup from scratch:

    Should resolve guest network issues after all this completes...
