I have Firmware: DD-WRT v3.0-r33006 std (08/03/17) running on Linksys WRT1900AC V2 Dual Band Smart Wi-Fi Wireless AC Router (2.4 + 5GHz) - (Certified Refurbished)

I have ath0 (5ghz) operating as a client to another access point. I have ath1 (2ghz) operating as an access point to serve the apartment.

Occasionally ath0 loses "sync," as in it either: 1. disassociates completely from the access point. 2. it stays associated, but loses it's IP address.

For the most part it is scenario 1 (total disassociation), I have seen scenario 2 just twice (just ip).


I'm looking for a way to make ath0 reassociate and re-request the ip, and etc. The whole process.

I have tried (from my memory)


ifconfig ath0 down
ifconfig ath0 up


ifconfig ath0 down
ifconfig ath0 up
iwconfig ath0 essid ACCESSPOINT




What is the correct sequence of commands to cause the wifi to reassociate succesfully with the external ap?
