    From AC87U to AC3100 - now bad bufferbloat

    I had my RT-AC87U in AP mode without QoS enabled. Because of the issues I was having with the 5GHz band, I replaced it today with a RT-AC3100. With the 87U, I always got an A or A+ for bufferbloat at the DSLReports speed test (this is wired, not wireless). Now with the 3100 (also in AP mode...

    RT-AC87U with 380.59 alpha 2

    I installed this firmware over 380.58 without clearing NVRAM and reconfiguring, and ran in to a few issues: 1) After entering my login credentials, I would get a blank screen. This cleared up after a second reboot but returned again later. 2) The Network Map (client list) showed no entries. 3)...

    Eastern Time Zone wrong DST end date

    For the time zone setting, if I choose EST (GMT-5) is shows daylight time ending the second Sunday of October instead of the first Sunday of November. For those you of in that and other time zones in the U.S. and Canada, you might want to manually correct the end time. The interesting thing is...

    RT-AC87U - AP mode - Quantenna weirdness

    If you look at the system architecture block diagram of the RT-AC87U, the Quantenna SoC / 5GHz radio is basically a second router within the router. There were a few times in the past when the Quantenna SoC crashed on me, some times would try do reboot using BootP with the MAC address of...

    RT-AC87U Traffic Monitor has weird WAN stats

    Does anyone with a RT-AC87U (378.53) have WAN stats that make any sense in the Traffic Monitor? Even with CTF and FA acceleration disabled, my stats (especially WAN) make no sense. For example, traffic on 5GHz wireless within my LAN network is counted as WAN inbound traffic. So my local...

    Script to access bridged cable modem via WAN

    My scripting-fu is weak, so I'm asking for some help from the community. I just replaced my Motorola SB6120 cable modem with a Cisco DPC3848. Both use 192.168.100.1 as the IP address to the GUI. With the Motorola, I could access the GUI by simply entering that IP address in the browser. With...

    DNS queries of local IP addresses?

    Is it normal for local private IP addresses and names to be sent out to the public DNS server? e.g., For example, I have a local IP address 10.0.1.13, and I see DNS queries for 13.1.0.10-in.addr-arpa, which is then answered by the server as "Refused". This is happening to many of my local IP...

    RT-AC66U in repeater mode - missing network shares

    I have a RT-AC66U in repeater mode and a RT-AC87U as my main router. Both are running Merlin's 378.50 beta1 firmware. In noticed recently that any Apple computers connected via the repeater don't see SMB or AFP shares on computers connected to the main router. A Gooooooogle search showed...

    RT-AC87U with RT-AC66U repeater

    I just bought a RT-AC87U today and upgraded it to RMerlin's 378.50Beta1 firmware. Everything (except openVPN) is working great. I repurposed the RT-AC66U as a repeater and it's also working great. I have a couple of questions I hope the community here can help me with. 1) I don't see a...

    tcpdump on RT-AC66U causes reboot

    This post is kind of hail-Mary. When I had Merlin's 374.43 firmware on a RT-AC66U, I could ssh to the router and run tcpdump (I installed it via entware), and it would run flawlessly. I could even send the info via wireless to my MacBook Pro running WireShark like this: ssh name@router...

    RT-AC66U MAC addresses

    Some time ago, I accidentally hit the MAC Clone button, so I've been running my router's WAN MAC set to that of my QNAP NAS for some time. I have no idea how that happened. Anyhow, I cleared the MAC address, applied and restarted the router. Now my cable modem is showing an ASUS MAC...

    High ping times to RT-AC66U with 3.0.0.354.27

    Strange behavior. Over wireless, the first hop to my router is ~2ms. Wired connections (either from my Mac Pro or Windows 7 box) jump all over the place, with pings up to 10ms being quite common. Example from my Mac Pro wired: Mac-Pro:~ doug$ ping 10.0.1.1 PING 10.0.1.1 (10.0.1.1): 56 data...
