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 ;-)

Disabling Airtime Fairness worked for me to get my HP printer working with my Asus RT-AC3100. Thank you!

I just got the AC3100 (RT-AC88U) and a Canon MG3600 and I’ve been pulling my hair out. I thought it was the WPS process that was messed up until I saw that the printer had been given an IP via WPS and would even print the network settings correctly as connected to the WIFI! Once I disabled “Airtime Fairness” the setup FINALLY succeeded fully. Thank you so much.

This is life changing! This has been driving me nuts for two years, to the point that I got a new printer. When the new printer had the same issue, i decided to google to see if it was my router. Now I have two working printers. Thanks!

Thank you so much, I would never get my Asus3100 router to AirPrint on my Canon MX922 without the instruction provided.

Thanks, your post pointed me to right direction. For me the critical settings with ASUS DSL-N16 were
Enable IGMP Snooping = DISABLE
Enable Packet Aggregation = DISABLE

This fixed our AirPrint problem with our ASUS RT-AC88U that we have been struggling with for months! Thank you! Just the Airtime Fairness setting took care of it.
