Suddenly a bit lower speeds from router (Orbi 853)
Orbi 853. FW: 7.2.7.15 (Had this issue also with 7.2.6.21) Not sure if there is a problem. Hopefully I explain it understandable as I am not very technical. The recent days I have experienced...

If your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

Try option #2 first...

Thanks I will try to contact my ISP regarding bridge mode.
I already disabled everything regarding wifi in the ISP router. On the display WIFI symbol does not light up either.
Regarding #2. Can't seem to find anywhere to do this:
"configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem."
These are the options I have.

Ask the ISP about the DMZ or IP pass thru. Hopefully it has one of those features.
Might give AP mode a try with the ISP rouoter and see if speeds are better...

I tried AP mode now. How do I do if I now want to enter the routers main login?
Can't use the 192.168.1.1 as I normally do?
