RAX75/80 Consistantly drops speed on both Ethernet and WiFI

Question

I purchased the RAX75/80 from Costco a few months ago and have it connected to a CM1100 Cable modem,. I have GB Service with Cox Internet. It will maintain 950-990 MBPS (ethernet) for about 24 hours, WiFi is extremely fast as well. However, it will drop sharply after about 24 hours or so to 150-280 on the ethernet port and the WiFi will be extremely slow as well. I've updated to the latest firmware and still nada. Once I reset the modem everything is fine for a while. QOS is not enabled. I got the usual Factory Reset your router advice from Support just before my free support ran out. Has anyone solved this issue with a factory reset?

I've seen several suggestions on getting this to work in the community but so far nothing I've tried has been successful. I bought this thinking it would be better than the Cox panoramic wifi modem which is a piece of garbage. I've been extremely disappointed so far.

Are you using wan port aggregation?if so, i'd highly recommend disabling it on the cm1100 and the RAX and just using a single connection. I've found many ISP's have issues with port aggregation.&nbsp;

I've attempted to get port aggregation to work with no success so I'm ust using a single connection.

so its solid for 24 hours and then drops?&nbsp;have you tried connecting a pc to the modem and using just that for 24+ hours to see if its a modem or a router issue?&nbsp;&nbsp;

I wouldn't say it's solid for that long.&nbsp; Basically I'll check it whenever it seems slow which is about once a day.&nbsp; Most of the time it's slower than mollasses.&nbsp; Connecting just my pc would not be practical because we have 3 of us working from home every day.&nbsp; It was doing this before that though.&nbsp; I have bypassed the router when it is slow and done a speedtest that way and it's fast so it's definitely a configuration in the router.

do you have the RAX75 or 80?What firmare is on it?&nbsp;did you ever try reinstalling the firmware to it over a hardwired connection, then factory reset, with a clean install (not from backup)?Just in case the firmware was corrupt on it.&nbsp;Another thing to try is downgrade a version of the firmware. The rax devices were released even before AX spec was released and occasionally get a bug with firmware upgrades. Its where sometimes the "latest isn't always the greatest".&nbsp;&nbsp;
