AP10 / AP30 behind RED doesn't always reconnect

Hiya

I had two AP10's behind a RED (now a AP10 and AP30) at a remote site providing there wifi.

However we are finding they don't always come back to an active status when the RED or our ASG220 is restarted.

I have got the RED in split mode and have 1.2.3.4 in the networks. I have tried to removed the 1.2.3.4 and add it back in but this didn't work.

After much trying to get it to work with v8 I waited till v9 and still have the issue so I thought it could be an issue with the AP10's so brought an AP30 and sent it down there. It showed up in my ASG's webadmin but as soon as i assigned it to a group and gave it a name it went offline and hasn't come back online.

Any way I can get these to be more reliable and connect back up after a reboot / internet issue at either end?

Thanks in advance

Andy
