    Ping Latency Issue with Merlin 380.70 on RT-N66U Router- any advice is appreciated

    Hi there! Like the title says, I have an N66U with 380.70 currently on it (latest supported version). Everything is working great (connectivity, range, customization is amazing) except for a ping/latency issue. If I ping google from my PC connected to the router, every 5-10 seconds it spikes to...

    "6 clients are connected to RT-N66U through this device"

    Hello! I have been getting this icon in the devices list where it says that multiple clients are connecting to the router through this device. What exactly does this mean? Also this same device that the "clients" are connecting through (an iPhone 6) has been experiencing network downtime for...

    [RT-N66U] slow internet speed only on some protocols/servers?

    Greetings! I'm looking for some suggestions on how to diagnose the following problem. I'm on a gigabit internet here (Vancouver, Canada), and I can run speedtests against some servers and get 900/900 mbit/s easily. Then, I try to download a file over http on a server under my control on AWS...

    [RT-N66U] - 5Ghz drops

    Hi everyone. I've had this router for maybe 3 years now and though drops were always present, they were never this bad, as it's now happening several times every day. It's set to 40Mhz, channel (not auto) 136. There's no 5Ghz congestion, only one other AP in a different channel. The router's...

    Asus RT-N66U / CTF aka HW-NAT

    Hi, I'm using the RT-N66U with Merlin 380.68_4 firmware. It works great. Now I'm not sure if Merlin supports Hardware Nat (called CTF if I'm correct?)? I have it set on Auto and it says enabled. I have 100/100 Mbit/s at the moment (PPoE over WAN), but I will upgrade to 1000/200 Mbit/s. I wonder...

    I have an Asus RT-N66U that was running Asuswrt-Merlin 380.67 and had a working port forward rule configured this way, but after upgrading to 380.68_4, it has ceased to work: Port range: 35000 Local IP: 192.168.1.136 (manually assigned IP to wired NVR) Local port: 35000 Protocol: TCP I have...

    Hi, I have n rt-n66u running firmware "3.0.0.4.374.43_27E5j9527" of Johns. I have recently upgraded my broadband to 300mbps, however it seems the N66U is struggling to provide this speed and tops out at ~230mbps. I've monitored cpu whilst trying a speedtest and can see the cpu average shows...

    RT-N66U randomly dropping connections

    My router (RT-N66U) has been dropping both wired and wireless connections quite frequently recently. I know for sure it's the router because when connected by wire I can't even connect to the router home page (it just keeps loading or times out). It has done this in the past but seemed to stop...

    RT-N66U and firmware 3.0.0.4.380.7378 - comments?

    It has been three months now since ASUS released firmware 3.0.0.4.380.7378. There are relatively few posts related to this firmware and the RT-N66U. Does anyone who has installed this firmware on an RT-N66U have comments, good or bad? Thanks!

    RT-N66U & 380.66_2 Gigabit ethernet not functioning correctly

    Was there a new setting for this I'm not aware of or should I just download and reflash a new copy of 380.66_2? Any questions on configuration just ask.

    SNMP shows incorrect SPIKED traffic on RT-N66U Merlin

    I upgraded my Asus RT-N16 (Tomato) to RT-N66U (Merlin) and my old router had beautiful accurate SNMP graph using NetUse Traffic Monitor on my mac. Now the graph is SPIKEY and not accurate (it shows spikes of 9Mbps and my max DSL is about 5Mbps). I ran and upload and download test, and spikes...

    [RT-N66U] Upgrade to John's 374.43 or stick with Merlin's 270.26b?

    I've been running the 270.26b firmware on my N66U for years and haven't had issues. Only recently I've noticed the occasional eth2: received packet with own address as source address but otherwise it's been fine. I'm curious though, is there are any performance benefits to updating to John's...

    Port 10 Open & Responding to ICMP request?

    I recently got AT&T as my ISP. The combo-box router they left me with is a Pace 5268ac. What a nightmare of interface. I've set my RTN66U on what they call DMZ+ so that it may access WAN directly, do all the firewall business & handle my LAN/WLAN. When I do this everything seems to work find...

    Can you overclock CPU on Asus RT-N66U?

    Firstly I have to say I think the Merlin Firmware is brilliant. :) I was wondering if there is a way to overclock the router CPU through Merlin? When router CPU is running at 99% the temperature stays static at 45 degrees Celsius. Background to my question... I have been trying to get faster...

    N66U eth1 and eth2 not found (no wireless)

    I have been using DD-WRT on this N66U HW Ver:B1 for over 3 years without issue. Suddenly I noticed it was no longer connecting to my main router over wireless (using N66U as bridge from my AC3100). Devices connected to it over Ethernet would not receive any IP address. I've restored multiple...

    Hi All, I have just upgraded the firmware for Asus RT-N66U from 378.53 to 380.64_2. Once it has completed I have been forwarded to the new router login page which is now web based. It turns out that after the upgrade it no longer accepts the password I had before nor the default "admin"...

    What is the max number of concurrent wireless connections on an Asus rt-n66u?

    To clarify - I'm talking about the max number of client connections, not TCP/UDP connections. In other words, the number of devices that can be wirelessly connected concurrently. I'm running Merlin 380.63_2. Is this limit in hardware or firmware? TIA.
