RAX120 Dropping Speed

RAX120 Dropping Speed

A day into my new RAX120 and I'm running into issues with WiFi dropping speeds down to 20/30 Mbps or dropping connection altogether on 5GHz. Upon reboot, speeds come back to normal which on WiFi devices I range in the 700-800 Mbps range. I am link aggrogated from my SurfBoard 8200 and read in another post the link aggrogation may be the culprit. I'm running a wired connection off my multigig port to a 2.5Gbps network adaptor on my main PC and have been hitting speedtest averaging around 1050Mbps with peaks into 1100Mbps, so I'd rather not diable LAG as that's the main reason I even upgradted to the RAX120 in the first place. I have QoS and Smart Connection off to ensure my devices aren't being throttled by the router itself. The other posts I've read are dating back into mid-2019, has there not been a solution since? Is there an older firmware that supports LAG that is known to be stable for the RAX120? Pretty disapointed 24 hours in I've had to reset the device three times to address WiFi connection issues.

Re: RAX120 Dropping Speed

Its not just the RAX that's struggled with LAG. The Arris SB8200 does as well. I've got it and had to put it in a closet because LAG wasn't stable on it. The CM1100 was more stable in terms of LAG than the SB8200 in my experience. 

As much as it pains me to say, try disabling LAG first. We know its got issues with both arris AND netgear. rule that out first. If the speeds stay good with LAG disabled, then we know thats the issue. Either for the Arris or the netgear.  If it doesn't and your issues are only over wifi, I'd pm @Christian_R   Christian has access to beta firmware for the RAX120 that could potentially benefit your device if you're willing to try beta firmware. 

Current Setup: CM2000-> RBK750-> GS716v2-> RAXE500-> Pi-hole->

Re: RAX120 Dropping Speed

Thanks for the helpful info! I'll continue to troubleshoot as I move forward and try switching LAG off to see if it helps remedy my issues however it appears the speed drop is only affecting WiFi. I'm running into the same DNS issues others have reported on all devices and that's been the bigger problem as it’s actually causing loss of service. Looks as if I’m not actually losing the 5Ghz broadcast, it’s just that all devices go unresponsive when the DNS issues arise (in the two days I’ve been running this router has occurred about 5 times). I'm running a Pi-hole so my router is only set to that as its only DNS, which has been operating just fine well before the introduction of the RAX120 onto the network. It appears reading the forum the DNS issue is unrelated to the actual DNS you’re pointing to, but rather a configuration issue with the firmware itself. I found aside from rebooting the router, if I log in during this DNS issue and simply reapply the same DNS settings I had it’ll resolve itself once it “applies” the settings. I’d be open to trying a beta firmware if it’ll address some of my issues. At this rate, I’m giving this a bit of time while within my return window of the device to see if it’s going to be worth holding onto or not.

Re: RAX120 Dropping Speed

DSN issues still seemed to be present even with LAG disabled, fortunately that doesn't seem to be the culprit. Though haven’t noticed any WiFi slowdowns during the troubleshooting so can’t rule it out as a cause for that. I know many are searching the boards with similar problems so will seek out beta firmware and update any progress made with it. With LAG re-enabled hit my best speeds yet - almost making the trouble worthwhile.

Re: RAX120 Dropping Speed

When you said dns it got me to thinking. I pinged 8.8.8.8 google and it worked. I changed my router DNS to 8.8.8.8 and my internet and all devices are back up. Granted it's only been a minute but it instantly worked without rebooting. Hope this fixed it...for now!

Re: RAX120 Dropping Speed

Nice! While it's not a perfect solution, not having to reboot the router every time you're facing an issue is a huge plus. Not sure what firmware you're on; I tried beta .115 and faced the same issue. I went to .118 two days ago and *knock on wood* haven't had any issues since. Worth looking into if you're still on .114

Re: RAX120 Dropping Speed

I was on 114 but upgraded to 118 today to see if it would fix the issue...which it didn't.

Re: RAX120 Dropping Speed

Wanted to update after a few days of .118 and address my initial comment of “no issues yet”. The good news is the DNS issue doesn’t seem to be as large of a problem on .118. The bad is WiFi networks are still randomly dropping to speeds ~ 20 Mbps and remain that way until a reset. That’s where my other big issue comes into play – I’ve been having issues when sending a simple reboot command to the router either through the web interface or the app, the router does a whole factory reset, and requires setup on app only (which is a huge pain, why can’t we set up directly from a wired connection if we wish?). This makes a simple reboot to address my slow WiFi speeds into a whole process of reconfiguring the router from scratch. I’ve started to simply restore settings from a saved file each time I have an issue instead of rebooting the router and seems to address the issue for the time being. With the move to telework we’ll see if I run into any severe difficulties enough to ditch the RAX120 altogether. Hope everyone out there is staying safe amongst our current situation.

Re: RAX120 Dropping Speed

What kind of network adapters do you have?  I have the same issue with network speeds dropping after a 30 minutes or so to a few hours, but only for network adapters using the Intel AX200 chipset.  This of course means I can't even use 802.11ax since pretty much all (I've never even found one that isn't) network adapters that can do 802.11ax are AX200 chipset.    You probably don't even need to reboot your router, just disconnect from wifi from the device and reconnect and your speeds will go back up again.

Re: RAX120 Dropping Speed

Thanks for the tip! The only devices not hardwired (and aren’t IoT devices) that are able to run a speed test are my laptop and phone, both of which only support AC. I have tried disconnecting and reconnecting during the speed drops to no avail. The main draw to upgrading to the RAX120 was the offering of LAG and a multi gig port. Without any AX devices I have AX disabled for the time being, as I saw in another post that could have some impact. Something I picked up from another Netgear user having DNS issues is to disable “Automatically adjust for daylight savings time” in the NTP settings. I’ve disabled it and along with running .118 haven’t had DNS issues in some time – though I can’t say for sure it wasn’t the new firmware alone that helped.

Re: RAX120 Dropping Speed

I have several wired devices and, after few hours to days the speed also drops. Usually I have 120MB/s download speed and 110MB/s lan transfer speed, but after time they drop to 35Mb/s download and 50Mb/s lan transfer. At the same time webpages are hard to load (appear to be offline, but several refreshes later they open). At first I thought it was due to DNS, but I've tried ISP's DNS, 1111, and 8888, but the results are the same. A reboot solves all these issues, but I have to do it several times a week and it's really annoying.

AC devices also suffer from speed drop. AX is just another nightmare. I have 1 AX201 and 4 AX200, and they all drop the internet randomly after few hours. They all appear to be online (no exclamation mark on the WiFi icon), but I just cannot connect to anything, until I dis/re-connect WiFi.

Re: RAX120 Dropping Speed

For this so expensive router, after the latest firmware I noticed a big drop on my 1000 mbps fiber speed. I revert the firmware to the stock firmware and never use their nighthawk app and it seems I never had any issues at all. This bitdefender software is just one of their moneymaking styles. Correct me if I'm wrong.

Re: RAX120 Dropping Speed

What were you using that was not stock and what firmware version are you on now.

 

Did you perform a factory reset after updating?

Re: RAX120 Dropping Speed

All netgear firmware is stock! Bitdefender is a AV comany and not a 'style' but if you have multiple pc's and IoT devices it will offer protection as you can download Bitdefender for as many devices as you want for that one price. Its not really that useful on the router alone but does offer basic protection basically.

Re: RAX120 Dropping Speed

I've been using netgear router for 12 years now and my last one was R8500. After automatic install of the firmware I noticed a degrading performance of the router.the first release it worked flawlessly and then worked like 1 to 1\2 year it became a piece of crap. I 

always have a fight with the internet providers. What a waste of money because I'm not buying cheap ones its their latest ones! On my RAX AX120, the first release firmware out of the box worked fine. The auto update is making it worse as I observed, this is just MY OBSERVATION!!!! No offense to whoever this KillerHippie is saying. So tired of seeing a very expensive router will just go down the drain, I decided to revert it the original firmware as if out of the box and hard reset it 30-30-30 like use before on old netgear routers of mine. MY EXPERIENCE after I used the nighthawk app with netgear armor on the last week of my trial because I dont want to buy it, my Iphone was

disabled for no reason that I cant open and have reset. I turned of my router and walla I was able to turn it OFF  and do reset.

I reset everything (what a waste of time) I have 32 loT connected to it like garage, switches and CCTV my house is fully automated.

So on the consumer end this is not a joke! Im just an ordinary netgear user and if this situation happens it cost me a lot of time and effort to connect all of them. What I did was to disconnect if from my at&t IP passthrough gateway, hard reset it to 30-30-30sec and reconnect all of my devices changed my password.This is my current firmware that you can download from the website. Im not suggesting you also do this,

this is just my experience and currently I have no more problems. Mind you I'm pretty happy with my lifelock coverage! if they get my info.

Re: RAX120 Dropping Speed

I know the auto update is a problem which is why I said turn it off and manually update. I also beta tested this router along time before its release for Netgear so know it very well. Don't do a 30/30/30 as modern routers NVRAM do not need that and it can cause corruption. Downgrading when there is security issues is your own decision but it could expose your router to some nasty security issues which Netgear will not help you with as you didn't keep your router up to date.

Re: RAX120 Dropping Speed

Well I finally resolved all my router issues.  Went and bough an Asus AX11000.  Range is way better, speeds are better, no drops ever, speeds never decrease for any reason, latency is better.  Basically all around beats the snot out of this pile of junk hands down. My RAX 120 is now relegated to paper weight status.
