Prior to CBK 752 Firmware updates (CBR750 -V4.6.3.6, RBS750 -V4.6.3.7), I was consistently getting 1.2gb - 1.4gb download speeds. Now it is below 650mb. Nothing else, besides the firmware updates, has changed. Netgear Team - Kindly review firmware and provide a fix!!!

Have still reached out to the forum moderators for the Beta bc the CBR750 has been rebooting on its own several times a day now.

Hello Blanca, Darren and Furrye38 - Blanca_O , DarrenM , FURRYe38 , It has been about 6 weeks since these firmware upgrades were introduced and have degraded performance of our modem router/satelite. I have spent several hours with Netgear support personnel, who have just asked for more and more logs and I have not seen a solution from them. For now, I have given up on Netgear Engineering/R&D/Support providing any update firmware, be it beta. There are bits and pieces of from various users, spread across various Netgear Orbi products - RBK752/3. RBK852/3, RBR750, RBR850, RBS750, RBS850,CBR750, CBR40, etc. and "rolling" back firmwares to prior versions on Netgear Community posts and Reddit posts!!! Can Netgear Support to put together a "FAQ" with steps, which versions of firmware to "roll-back" to, and specific to the products, such as CBK752? Thanks in Advance,Al.

Not sure if you tried this yet, but the satellite also has a factory reset pinhole. I previously had issues with my satellite and factory reset it and haven't had an issue since. Also, if there's a delete button next to the satellite listing when you view the connected devices (through the webpage), I would go ahead and delete it too.I am on all of the current firmware and after factory resetting both modem/router and satellite, I've had over 30 days of uptime.

Please open a support ticked with NG support and let them know what your experiencing. Can reference this forum thread as well. Thank you.
