Rax80 gets low bandwidth behind ATT BG210

Question

Good Afternoon,&nbsp;I have a perplexing low bandwidth on wifi issue that doesn't seem to be solved by putting the ATT router in ip passthrough mode. I discovered I get the max download of 600 mbps but only if put the rax80 nighthawk in AP mode. If I use the nighthawk as a router , it'll get 300 mbps max.A lot of articles suggested IP passthrough, disabling firewall features on the ATT router but this made no difference for me. It gave the nighthawk a public IP and wasn't NATing multiple times but didn't make a difference in speed.&nbsp;I also tried disabling AX features, smart connect mode on the Rax80 but this lowered the speeds a lot more, down to like 60 mbps.The nighthawk has been pretty disappointing since I first bought it with all the software bugs it has and now this issue. When I had support from netgear's limited warranty, the technician was telling me all the issues I wrote about were known but weren't being tracked anywhere that I could see and no known ETA for fix. I didn't realize about the low bandwidth issue though until recently.

What devices are you speed testing with? Wired is preferred.
What Firmware version is currently loaded?
What speeds are you getting at the ISP modem/router with a ethernet connected PC/laptop?&nbsp;

This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple of options,1.

Hi&nbsp;FURRYe38,Thanks a lot for your help.&nbsp;"What devices are you speed testing with? Wired is preferred."Wired speed is full as expected from the rax80 behind the&nbsp;ATT BG210 which is about 600 Mbps up/down.&nbsp;It's the wireless from rax80 that's the problem."What Firmware version is currently loaded?"latest available for rax80 -&nbsp;Firmware Version V1.0.5.132_1.0.69"What speeds are you getting at the ISP modem/router with a ethernet connected PC/laptop? "600 up/down"This would be a double NAT condition which isn't recommended."For the&nbsp;ATT BG210, the recommendations I saw were to put it in ip passthrough as the only option and turn off the firewall features, which I did. My public IP was passed through to the RAX80 but it didn't make any diffierence in speed over wireless. I also tried to disable all fhe features I could like AX mode and smart connect but it lowered speeds to about 70 mpbsFURRYe38&nbsp;wrote:What devices are you speed testing with?

Thanks again! I still would've thought that putting the ATT router in passhthrough for rax80 to get direct public IP and not have to route from 10.x network to 19.168 gateway and then NAT out to public would help but it doesn't. AP mode on the rax80 works great but I lose the few useful features&nbsp; thast it has.FURRYe38&nbsp;wrote:What WiFi devices are you speed testing with?Mac laptop and samsung phone since they have capability to test well as long as I'm close enough to router for 5ghz .&nbsp;How do you have the wifi settings configured on the router?&nbsp;&nbsp;Enabled:AXOFDMA in 2.4 and 5ghzSmart Connect&nbsp;2.4ghzenable 20/40 mhz co-existencechannel automode up to 1200 Mbpstransmit 100%&nbsp;5ghzmode up to 4800 Mbpstransmit 100%&nbsp;&nbsp;&nbsp;
