iPad Pro 9.7 WiFi connection issues

My brand new iPad Pro 9.7 is having major issues staying connected to my home WiFi 5GHz channel. The connection drops about every 30 seconds or so and I have to manually add the network back in. Also, when reconnecting it does not always take the password, and it takes several attempts before it finally accepts it.

Oddly, the iPad is rock solid when connected to the 2.4GHz channel and has yet to drop that connection. All my other iOS devices (older iPad and two iPhone 6's) have no problem staying connected to the 5GHz channel so I know its not a settings issue with the router. But just to be sure I put all the router settings to those listed here: Recommended settings for Wi-Fi routers and access points - Apple Support

That did not fix the issue.

I then went back to the Apple store to see if they could help me and they ended up exchanging the iPad for another one. The same exact issues exist with the replacement. I even made sure to not restore from a backup, and setup the replacement iPad as a NEW iPad. I then tried connecting to WiFi with the pre-installed OS and still had the same issues. I then updated the iPad to the latest OS 9.3.1 and it still exhibits the same issues.

I am at a loss for what to do next. I will be returning the iPad Pro 9.7 for a second time in two days. This was not ready for release.

SOLUTION FOUND!!!!

Router: Asus RT-N66U

Device: iPad Pro 9.7 (gen 1)

Decided to give it another go and did a little more Googling. Found an obscure post from 2014 on another forum, a Mac having issues connecting to 5gHz. Essentially the same issue as me but for a Mac and he had the same router. He switched channel bandwidth to 20MHz only mode and that fixed it. I was in 20MHz/40MHz mode. Made the switch and now I am on 5GHz rock solid for that past hour.

This issue seems to exist on certain iOS devices and the Asus RT-N66U router. I am quite shocked that this isn't a more documented issue considering how popular this router is.

General suggestions for Wi-Fi issues, maybe one of them will help....

1) Perform a Forced Restart:  Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Allow device to restart.

2) Reset Network Settings:  Settings > General > Reset > Reset Network Settings. Rejoin the Network again.

3) Change to Google's DNS:  Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4

4) Disable the QoS service on the router if available.

5) Reboot Router/Modem:  Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website). Verify your router is Wi-Fi certified.

6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).

7) Try device at another Network, i.e., neighbors’, public coffee house, etc.

8) Restore the Device (ask for additional for details if desired).

9) Go to an Apple Store for hardware evaluation.

Thanks for the fast reply. I've done pretty much everything on the list except #3. I'll give #3 a try. But I have done everything else on your list to no avail. #9 resulted in a brand new replacement.

For whatever it is worth I have seen a lot of conflicts with routers and iOS devices. Did either of the iPads work at the Apple Store. Surely they have a 5 GHz network to test it. If you end up getting another one I would test it at the store before taking it home.

No luck with #3. Issue still exist. One thing to note, sometimes when manually reconnecting I get the Incorrect password for "SSID" pop-up. I just recently got it about 10 times in a row before it finally accepted the password. This would also happen on the first iPad Pro I returned.

To answer your question, only the first one was checked out by the Genius Bar tech, unsure if he tried to connect to a 5GHz channel with it. But yes, that would have been a good idea before taking the one I currently have home. I just assumed the first one was a lemon.

As mentioned in the first post I have 3 other iOS devices, an older iPad 3rd gen and two iPhone 6's, working solidly on the 5GHz channel.

For whatever it is worth, I purchased a new router last year with the latest bells and whistles. Some of my devices worked well with it, some did not. A replacement did not help and neither did reflashing or reconfiguring. Ended up getting my money back and buying a different brand and it has worked flawlessly since. I have some devices on the 2.4 band and some on the 5 band, no issues. The router I initially bought works well for most so go figure.

All I can suggest is testing your iPad on another network with the 5 GHz band. Is your router configured for AC only or n/AC mode? The iPad should work in AC only mode but worth a shot perhaps - also different bandwidths.

Yeah I thought about trying the various router settings, but I feel like I shouldn't have to go to that extreme for the one iOS device that doesn't work on the current 5GHz settings. I have had multiple iOS devices aside from the current ones I own work flawlessly on the 5Ghz band with the same router and settings.

It is really a mystery why the iPad Pro 9.7 does not work.

For what its worth I have an Asus RT-N66U.

Glad it is fixed...      but gee, I recommended that yesterday...  "Is your router configured for AC only or n/AC mode? The iPad should work in AC only mode but worth a shot perhaps - also different bandwidths."

Yeah I replied after your suggestion that I didn't want to do the whole rigamarole of changing one setting, test, redo, change another setting, test, redo, so on and so forth...or essentially that I shouldn't have to do that. I still firmly believe I shouldn't have to do that when a large number of other iOS devices have connected to my 5GHz wifi and worked fine.

I actually was just going to return the iPad for good and just get the latest Air when I randomly stumbled on a 2014 post that described the exact same issue (on a Mac) with the exact same router. Gave it a shot this morning and fixed.

Still shocked this is still a very needle in the haystack problem considering the popularity of my router and the millions of iOS devices out there. I mean am I really the only RT-N66U owner with the new iPad Pro 9.7 running on fairly standard 5Ghz wifi settings? Maybe I am.

Also keep in mind that using the 5GHz band at 20MHz only will reduce network connection speeds. This may be irrelevant if all you do is connect to the internet but will impact device to device data transfers. iOS devices and Macs should work on bandwidths above 20 MHz. My iPhone is on the 5GHz band and my TP-Link router is set to 80 MHz.

Yes I am concerned by that even though my router only supports up to 40MHz bandwidth. I feel this is definitely an issue with the current firmware and hopefully an update will fix it. I really don't want to have to buy a new router especially since this one isn't that old and works great for me.

The Asus RT-N66U is by now a bit dated, it was first issued in December 2011 and does not use the latest standard for the 5GHz band, wireless AC. If it works well for you on the 20 MHz band then no need to upgrade.

Your router is limited to wireless n and the 40MHz band is the max it can provide. You would need AC to go to 80MHz on the 5GHz band (2.4 is limited to n and 40). A firmware upgrade will not make the router AC or 80MHz capable. As I mentioned, if your main need is internet 20MHz should be sufficient.

I guess in the PC world that is dated. Off topic, but is AC now a standard? I haven't been keeping up.
