    Monitoring network traffic for Grafana without SNMP devices

    Bit of confusion here I think. Not having DHCP conflicts actually, they are both handling different ranges. The WAN traffic issue is that the Deco sends traffic direct to the modem rather through the only SNMP capable device, the AC66U, so I won't be able to see any of that traffic.

    Monitoring network traffic for Grafana without SNMP devices

    I've recently setup a VM to run Graphite/Carbon/Grafana and I'd like to see be able to see network traffic in/out from the internet, but seem to be limited by the hardware that I currently have. Modem: Hitron CG3 - Bridging to RT-AC66U and TP Link Deco M5. Can't enable SNMP for snmpwalk Router...

    RT-AC66U Slow 5gHZ

    This is a common problem with the AC66U. Have you noticed that when you reboot your router or apply the settings on the 5GHz setup that your speeds go back to normal? I had this problem myself and tried all of the official ASUS firmwares and other recommendations I could find with no luck. At...

    RT-AC66U - WL-network really slow and needs a reboot freq

    Well, 4 days later and I'm still at full speed, no issues at all. 35_4 worked for me, thanks everyone!

    RT-AC66U - WL-network really slow and needs a reboot freq

    48 hours in and no slowdown. The laptop was off today, so no wireless clients for about 12 hours but my desktop remained on. So, the difference this time around is that firmware 35_4 along with something always connected to the network seems to be working!

    RT-AC66U - WL-network really slow and needs a reboot freq

    Well that's a relief to hear. I think someone in a different thread said they used to have the problem too and now not anymore, but from what I gathered they were running Tomato. I am almost at 24h now... my link speed stayed stable through the day when I checked, but now that I am home I am...

    RT-AC66U - WL-network really slow and needs a reboot freq

    It's looking better for me as well. I have been checking periodically during the day and link speed has remained 700-866Mbps. Transfer speeds have stayed the same since last night as well. Now this has me wondering though, for all of the days when the link speed has ended up crippled by the...

    RT-AC66U - WL-network really slow and needs a reboot freq

    Ah, I see. That makes it more clear, thanks. Testing it in the morning now I am still seeing 866Mbps link speed and when I dump files across the network NetMeter shows about 225 Mbps so that's fine. Though I am still confused as to why others are claiming 40-50MB/s transfer speeds when I only...

    RT-AC66U - WL-network really slow and needs a reboot freq

    Running 34_4 now after nvram reset, firmware installation, and setup from scratch. Guess we'll see if it stays stable until tomorrow. What I don't get is that my link speed shows 866mbps after reset, but then I run various network throughput tests (NetStress and NetMeter while copying files...

    RT-AC66U - WL-network really slow and needs a reboot freq

    I have seen posts and threads dating back to June with ASUS reps claiming a "fix is in the works". The problem apparently happens for the newer AC68U as well though, so I wouldn't count on it. 35_4 will be this router's last chance. I am getting close to the point where I can't RMA/refund...

    RT-AC66U - WL-network really slow and needs a reboot freq

    Hmm I haven't tried 35_5 but the problem existed for me even with ASUS official newest versions. :edit: Do you mean 35_4? I don't see 35_5 anywhere

    RT-AC66U - WL-network really slow and needs a reboot freq

    Did you ever have the problem with any other versions of official/Merlin firmware though? I think the point is that this is: 1) A major issue for some people who have this problem regardless of which firmware they are using 2) A complete non-issue for some people who do not ever encounter it...

    AC66U decreased performance over time

    This issue is not related to Merlin's firmwares. I had this problem even before switching. I switched to Merlin with the hopes that it had been resolved in his versions somehow but nothing works, not even the old 270_26b that everyone likes so much.

    AC66U best firmware?

    That's interesting. Networking is obviously not my specialty, but I gather that the 866Mbps I would like to see is from 2 streams of the 5GHz 80MHz band (433 Mbps) and that 175 Mbps is 2x20MHz (87.6 Mbps). So it seems like rate scaling may be the reason for the drop, but the scaling is maybe...

    AC66U best firmware?

    It mostly stays full signal as all of my testing has been from the same room about 10 feet away. The signal strength has sometimes dropped to 4 bars on the adapter status when it is crippled. There are no other 5GHz devices, and mine is the only 5GHz network showing on InSSIDer. I guess I'll...

    AC66U best firmware?

    Sadly, as expected, the 270_26b firmware did not help. 1. After installation: 866 Mbps 2. 24 hours later: 585 Mbps 3. 48 hours later: 175 Mbps 4. Reset: 866 Mbps I don't know what else to do aside from returning it, but then I have a ~3 week wait with no wireless...

    Asus RT-AC66U Performance degradation issue solved.

    Silvino did you reset your settings after installing Merlins firmware? Also, which version are you using? Is it 374_726 as Merlin has suggested? I am having the same problem, no available version of ASUS firmware has helped and mine has been degrading quickly, 2-3 days as you say would be nice...

    AC66U best firmware?

    Well, no difference or not between the stock/Merlin drivers, at least Merlin still has a 270 firmware available. I'll give it a try, though I'm not expecting much given that nearly everything I've found on the subject is people in the same situation and the threads end with no resolution so I'm...

    AC66U best firmware?

    I am currently using the official ASUS 3.0.0.4.374.979 firmware and since I got the router a week ago, I have had constant problems with degrading performance on my 5Ghz network. If I change any settings or reboot the AC66U it my connection speed jumps back up to 866Mbps (using Broadcom 4352...
