ASUS RT-AC88U WiFi and AirPrint wireless printer problem solution

The ASUS RT-AC88U is a pretty awesome router. However, out of the box, it’s a bit finicky if you try to print to it via WiFi or Apple’s AirPrint. It doesn’t seem to want to maintain the connection. I stumbled across this somewhat cryptic post and the suggested changes have solved my issues–at least so far. Here are the steps with a little more detail:

1. First log into the router’s settings.

2. Choose Wireless > Professional tab

3. Make the following changes:

-Modulation Scheme: Up to MCS 9 (802.11ac)
-Airtime Fairness: Disable (NOTE: According to one reader, this is the only change that matters, so try this first. Thanks Dan CC!)
-Multi-User MIMO: Disable (Note that this was already disabled by default for me)
-Explicit Beamforming: Disable
-Universal Beamforming (5 GHz only): Disable

Click Apply button.

4. Each of the Bands (i.e., 2.4GHz and 5GHz) have their own independent set of settings on this page. So, change the Band and repeat Step 3.

5. Finally, change the Control Channel to a specific channel (i.e., something other than Auto). Again, apply the change for one band, change the Band setting, and apply the change for the other band.

 

I’m not sure what real-world impact changing these settings has on the router’s performance; however, I haven’t really noticed any significant difference…other than my printer works wireless now ;-)

I have been fighting AirPrint issues as well as inability to connect to my printer via my laptop. In addition, I have a Marantz receiver which I should be able to control via an app on my iPad. What I found so very strange on my Marantz is that it also offers an option to connect using the specific IP address, however, when I would try that I got a message saying the device was not supported….. if I rebooted my Router some things might work for a bit but you check again 30 minutes later and now not working. I made the one simply change to Disale Airtime Fairness and poof, all my issues solved. Thank you, thank you, thank you!

My router RT-AC3100 with Asuswrt-Merlin v384.6

Thank you. You are the best. :-)

I changed setting to – Modulation Scheme: Up to MCS 9 (TurboQAM) and it worked. Then turned it back to MCS 11/NitroQAM and it failed.

I wanted this setting so I tried changing Airtime Fairness to Disable. It worked again. Leaving settings to see if it will work. :-)

Disable Airtime Fairness Worked!! I have been struggling with Apple, Epson and ASUS all of who don’t know about, or least are not paying attention to this issue. My wife was really pissed off and ready to kill me. Thanks for posting this, you ARE the best!

Nowhere in the settings of the ac55u I can find ‘airtime fairness’. Got two options really;

Enable IGMP Snooping
Multicast rate

When I change any values here my airprint seems to work but only tempory. After an hour or so I’m stuck with the same problem: can’t print from any iPhone/ipad onto my airprinter, message ‘no airprinter found’.

Please help anyone? I’m trying to find a solution for weeks now…

Thanks….I have an ASUS RT-AC88U router and have intermittent problems with connecting to my printer from 2 laptops – it has been very frustrating. I disabled the Airtime Fairness and that seems to have fixed the problem!

You’re the best! This, combined with installing the latest firmware update for the router, fixed the issues with our ASUS RT-AC3200!

Applied changes to the RT-AC88U to enable AirPrint printing from iOS devices (iphones and iPads) They worked immediately. My two iMACs connected and worked well. All on the same wireless network. BUT, the next morning back to the same place. iOS devices could not connect to the router. The iMACs continued to work fine. I entered the RT-AC88U’s control panel, logged out and the iOS devices worked! Please Help!!

No idea Jerry. Sorry. It’s an odd problem and, so far, no one else is reporting problems after making the setting changes. I did a test–I rarely print using AirPrint–and the fix is still working for me. Wish I could help.
