RAX80 regularly disconnects devices, then they reconnect
I recently “upgraded” from an R8000 thinking I would have better connectivity and faster speeds. Since purchasing the RAX80 I continually have devices drop their connection at random, then they reco...
My experience with this problem is slightly different. In my case, the RAX80 simply slows a specific (random) system's connection down to a crawl. Rebooting the system dows nothing to fix this. The only fix I've found so far is to reboot the router and problem is gone.
Tech support has suggested changing the MTU setting to 1468. (Advanced>setup>Wan Setup) So far, I haven't noticed any improvement from this.
So they made another suggestion I haven't had the opportunity to check out yet. Here it is:
">>click on advanced on the top of the page
>>Then Select Advanced Setup
>>under Advanced Setup click on Advanced Wireless setting
under Wireless Advanced Settings (2.4GHz b/g/n) under Fragmentation Length (256-2346): changed the number 2346 to 2300
for CTS/RTS Threshold (1-2347): change the number from 2347 to 2301
do the same for Wireless Advanced Settings (5GHz a/n/ac)
Hit apply.
After this please observe the connection at least six hours."Perhaps this is worth a try. I have some other problems with this box. If they can't resolve them, I'g going to ask NetGear to buy the RAX80 back or replace it with something that is stable enough to actually work correctly. - My own optinion is that they shouldn't be messing with public domain code to run this box, generally, this has too many glitches and security issues. - You'd think they could afford to have professionals writing the firmware for these systems.
what I found is if you enable both AX feature and MU-MIMO at the same time, then the router will disconnect devices after a while, so I have disabled the MU-MIMO which is not doing much anyway. but the new 70 firmware seems to fix that already. maybe you can try to disable the MU-MIMO if your router still got problem.
another issue maybe your neighbour is using the same DFS channel as you do , once the router detect it , it will try to switch to other channel, it also causes some problem sometimes, you can try to use 48 channel first, I have been using 60 or 64 channel and now very stable.
I see Walmart is now selling these off for $299. Netgear must be dumping these bricks since they know they don’t work.
With the latest firmware (RAX80-Firmware-Version-1-0-1-70) I still have to power cycle the router due to it locking up. It's happening more like once every day or two rather than the 2-3 times a day it was doing before. Based on the lack of support/feedback I won't be a future customer.
I upgraded to the latest firmware and still have the same disconnection problems. I gave tech support a call and have arranged to exchange it for a new one. Not sure that will make a difference, but it's better than the situation I'm in now. I'll post a follow-up.
I have had some success playing with some things.
I have downgraded to Firmware Version V1.0.1.58_1.0.24. Rebooting 2 to 3 times a day wasn't working for me and since I downgraded, it has been much more stable.
I noticed that the 5ghz channel was disappearing alot. I put most everything on the 2.4 ghz channel and things have been working well. I have a lot of Amazon devices and they seem to be the most sensitive.
I changed NTP Settings to use nist.gov https://tf.nist.gov/tf-cgi/servers.cgi
I changed the 5 Ghz channel to a static 64 - Because everything got downgraded to the 2.4 ghz channel, I am just now starting to test how this will work.
Once I verify that the 5 GHz channel is working fine with these settings, I will upgrade the BIOS to the latest and see how that works. Thanks to the other members who made several of these suggestions.
