Which WIFI extenders work best with this 5G router? I see T-Mobile promoting Google Nest mesh systems. Who has experience in extending their Sagemcom Fast 5688W Gateway?

@Danh525 I do not have experience with “extenders, only mesh wifi router setups. If they are promoting it I would think it's compatible. Maybe others have some experience to offer. 

Good luck.

@Danh525, I have the Arcadyan KVD21 and two TP-Link RE305 extenders.  They work perfectly with my gateway.

I have the Google mesh routers (2 routers, no point) and have connected it to the T-Mobile router. They act as extenders and cover more ground in the house. The mesh network has been great but the weak link in the setup has been the T-Mobile 5G router. I have a Nokia 5G21 which works well for some of the day and then gets bogged down after typical work hours.


From everything I've read and looked at, the Google mesh system works with the T-Mobile routers, for sure. They have instructions how to use it as well as how to hook them up.


Hope it helps.
