BR20 Phone Connection Issues after 2.3.1.58 Upgrade

[jvegasatx]

I have not been able to connect to my Orbi wireless LAN on a smart phone (both Samsung and iPhone) since upgrading to the v2.3.1.58 firmware.  The logs show DOS Attack: ARP Attack when trying to connect.  Connecting PCs are not an issue.

Error displayed on the phones is "Authentication Error."

Try a factory reset on the RBR and setup from scratch. 

Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
What WPA security modes are you using?

Thanks for the reply! 

I performed the factory reset, downgraded firmware to 2.3.1.48, set 2.4 to 11, changed to long preamble, set 2.4 to 25%, and disabled daisy chain. so far it has kept the connection for about 3 hours.  i haven't noticed when the wireless connection to smart phones begins to drop so i am now trying to keep track of how long it maintains connection.

Try the reset and same configuration when you upgrade to v58 at some point.
