Hello folks, can everyone please log all the issues they are experiencing with the RAX40 router on 1.0.3.80 firmware under this thread, I see there are several threads going on about the issue, figured if we collect them all under one location, Netgear may take a look at the issues? My issue are; The firmware broke the connectivity with the EAX20 WiFi Extender, extender can not connect to the routerSame situation doesn't exist with EX7500 RouterWith Smart Connect I experience some wifi connection drops with mobile devices.

I just joined the forum and came here to talk about this. Since I've upgraded (from 1.0.3.64) the router has been unstable. Initially I thought it was because I was starting to enable some of the wifi 6 features, but after setting everything back to how I had it prior to the upgrade, I still have issues. Here are the things that don't work properly for me Smart Connect - when enabled, my wifi devices which support 2.4G and 5G will drop from the network for several seconds. I thought it was a Smart Connect feature, but I disabled it and I still get the issue. This (disconnects) wasn't an issue before this firmware. I run 2 DHCP servers (primary/secondary) on the network. I have Guest Wifi is a separate SSID but it is "allowed to see devices on my network" - and should get an IP from these servers. However, they connect to the SSID but do not get an IP address. This also was not an issue before this firmware. The router "stops" responding and the web interface doesn't respond. y that, I mean, I cannot ping the router IP and cannot get on the admin web interface, but can still get to the internet. Devices connected to wifi can ping other devices, just not the router IP. The only way to get access back to the router is by rebooting it. I've done this 5-6 times since I installed the firmware on Sunday 2020-06-14. This ALSO was not an issue before this firmware. It's very frustrating. I haven't had my router for a long time - longer than 90 days, but less than a year. I'm actual VERY unhappy with it. Granted the amount on money I spent isn't a lot, but I've had cheaper routers that performed better and provided better functionality - I got this one because of 802.11ax. Working with this router makes me think of the scene in the movie Office Space where they smash the printer with a baseball bat. If I had a baseball bat, I probably would have smashed the router by now. If I didn't actually NEED to use the router, I'd factory reset it and find every single flaw by testing and documenting everything meticulously. If this router keeps "working" like this, I'm going to order a different router and just bin this one. And NEVER buy another Netgear device. Sorry that this has become a rant!

I forgot to add another issue I had, though this one I had before this firmware. I'm not sure when it was introduced, but I was reminded of it by reading some of the other posts. Devices that connect to 5G are sometimes getting denied access even though the PSK is correct but connect fine not the 2.4G SSID. This gets "fixed" with a reboot. And I said that sometimes the router stops responding but I can still get to the internet, well I had also noticed that sometimes that's not the case, but thought it was my internet provider. It's possible the router crashed and rebooted. Again, this didn't happen until this firmware. I can't reproduce it so I don't always know when it's one thing or another. Now this is so frustrating because with COVID restrictions, my wife and I are both working from home and notice these issues more frequently.

Hello, A brand new issue with 1.0.3.80 : after "some time - less than 2 days" Attached Devices is corrupted : it shows only wired or not the 5GHz or ... or some strange unknown devices with IP address out of local domain... BRRon

Have the same issue as all the others. Today my ssids won’t allow anything connect clawing wrong password. I get disconnects, reboots, slow connection et al. I’m diasspointed. Went through tech support last week and thought it fixed it. This is a defective product due to firmware, Netgear deserves to give us Our money back. This is a joke. Stand with me all who posted. I don’t like saying 200 bucks for a bad product I owned in six months is a fair loss. This is garbage. Makes working from Home a nightmare.

Hello, please let us know your choice as I'm/w're bored with this so bad product !!!! BRRon

  very disappoint with netgear. they should TAKE DOWN this defective firmware that is causing wifi drop. they don't because they want people to contact them and charge them for simple reverting back. take the firmware down and issue a new one once is fixed....very bad service netgear....

  Reveted to 62 no luck.
  Reset to Factory settings, no luck.
  Went back to my little old Trendnet, no problems now.
  Whish I nevee spent so much on this device, at least it was on a Black Friday sale.
  Can't disable coexistence because my BluRay uses the 20Mhz network and my other devices use the 40.

    ok, what i learned is to download the older firmware version from Netgear website, look for the older version
    V1.03.64_101 and go into the Admin settings of the route and update firmware manually.
    
    After i did that everything works again back to normal. It tooks me a few days of playing with setting and resets, but today i downloaded and tried the older version and it works
    
    give it a try. Also turn off auto updates so it doesnt happen again, and hopefully another update will come out
    stay away from 3.80 version

Picked up this router a while back to use as an additional simple access point. Updated the firmware to 1.0.3.80 and then configured it to serve both regular and guest wifi signals on 2.4 & 5ghz. Having the same issue I've seen lots of threads about, after a while the router stops responding and all my connections drop. The first few times seemed to be about 8hrs apart. After that I fiddled with firmware changes and had a few days stable until it crashed.

For a few of the crashes I've taken UART console logs. Seems to be an issue with the firmware. The firmware hits some kind of error condition and the router ends up in a loop which can only be fixed by a power reset. A few samples from the UART console:

First sample (error snippet only, I have a full log available though):

Maybe this will help netgear determine the what the issue is and get it fixed in the next update. I can provide more information upon request if it'll be helpful.

Good info for netgear but I doubt they really care. They will just roll out a newer router and forget the ones who purchased the older routers, less support and obviously not fixing the issue after 1 month now. Even within the last few weeks netgear has 79 routers with security flaws. I am just going buying different brand for now on. Email support they can careless. The answer you get is roll it back. Meanwhile we are open to security vulnerabilities and we can't update.

For me is RAX40 really unstable. It connect and disconnect all time with LAN, 5Ghz and 2.4Ghz on Firmware 1.0.3.80.

And I have noticed behavior of 5Ghz. I choose a wifi channel, but the router always go back to channel 36 even if this is the worst channel. I belive it crash, becuse I can see channel numbers av changed in Wireless Settings (5GHz)

FYI, like a lot of us, I had serious stability problems.
No issues for 2 days and then wifi breaks for all the home devices. Ethernet was stable.
It happened 3 times in the week.
Checked and modified my Wifi settings stable for a couple of weeks :
Disabling Smart Connect and having the same SSID for 2.4 and 5ghz
Disabling Mix mode WPA2/WPA3 and using only WPA2 AES

Just FYI.
Hope we will have soon a good firmware....

    The problems remain. At a frequency of 5 GHz, the channel is reset to 36. Sometimes, communication with devices connected at a frequency of 5 GHz disappears. I can not connect to the hard drive that is connected to the router. I hope that they will fix the problems in the new firmware ...

So just updated the firmware and now cannot connect to the router with the app or via a browser. My 2.4 network is showing but nothing can connect to it using the correct passcode. I have no idea how to "roll back" the firmaware, especially when I cannot connect to the modem at all. Why in the world would you allow this piece of crap out into the world completely untested?

Hello all,

Here is a quick update following multiple failures right after the latest FW update.

- I disabled Smart Connect. I am using (like with previous FW, the same SSIDs for 2.4 and 5ghz)
- I disabled Mix mode WPA2/WPA3 and using only WPA2 AES

3 weeks without any issues.

Hope this help. I stick with the latest FW without any new FW "benefits"...
