RAX120 Connectivity Issues

Bumping this thread because I, too, am experiencing issues with this router. I "upgraded" from the Airport extreme and to say I'm disapointed is an understatement. Multiple times an hour on different devices I'm experiencing dropped connections. Sometimes my devices are indicating that I'm still connected to my Wi-Fi network but network requests just drop out. I have to toggle my wifi on and off to get my connection working again. It doesn't appear to be a DNS issue as even requests to 192.168.1.1 were timing out. Other devices do just drop the connection and I have to manually reconnect. My most frequent experience is on my iPhone where I'm toggling my wifi a good 5-10 times an hour. It's beyond ludicrous and aggravating, especially given how much I paid for this router. I don't believe I have a double NAT issue as my router connects directly to a Spectrum modem, not router, and I don't have any other routers on my network (I do have a switch). Also, my internet port ip address isn't 10.x.x.x or 192.x.x.x. My firmware version is 1.0.1.136.

I'm beyond my return by date but am still under 90 day support. Any suggestions?
