    from Ontario on November 1, 2019

    I was impressed with this router and relied on the Previous experience I had with RT66U router that was excellent unfortunately the story is different with this one. The hook up is so easy and from the first moment you get amazing wireless speeds, however this will not last unfortunately every few hours the routers seems to be dropping to extremely slow speed there is no way to get it out of this except by restarting I contacted asus support changed some settings worked for few days and problem started to happen again, ended up putting router on an automated power cycling once per day but then the idling seemed to happen more than once per day and it really becomes a pain every time I need to go to the net to restart the router to ensure speed is good. Avoid this completely

  • Firmware update disabled 2.4 operation

    from  on October 20, 2019

    Bought it,hooked it up,it worked great! Less than 24 hour later I decided to install the firmware update as I had received the notification on Asus app. Firmware updated successfully however shortly afterward the 2.4 side stopped working. I did factory reset and re-installed everything still nothing on no internet on the 2.4 side,the 5 side remained strong. I checked online and many others have had the same issue. Told my story to salesperson at the store and they had heard this too. Salesperson recommended returning the router,buying the same router again but not updating the firmware ever... Ummm,No. I am returning the router and buying something different. 1 star is all I can muster.

  • It's a technical review

    from  on September 23, 2019

    To begin with,i would like to let you know that i am a professional Network Administrator,routing and switching is my specialization. I have been using Asus RT1200 for a long time. I never had to reboot it or had any problem with it. The only issue is it supports upto 100MBPS. Recently i have upgraded my internet speed so i bought asus rt3100 since Asus won my trust. Immediately after setting up the new router i realized that i am getting full speed 300MBPS doing speed test,but Youtube _other streaming sites started to load at 360p-480p,which is insane. I was suppose to get even 8K without any trouble. And also found too much latency _jitter with VOIP calls through different apps. I waited for days to see if it the issue with my ISP. Then also waisted countless hours doing Google searches and playing with QoS feature. but couldn't solve the issue. Then i plugged back my old router and BOOM!!! all streaming services and VOIP calls came back to normal. Going to return this tomorrow.
