What's the best supported router for wiz550io?

I have three wiz550io modules and sometimes i get troubles with them connecting and getting an ip using a Ubiquiti power Apn. however they seem to always work fine on draytek routers.

They even seem to have more troubles with 10/100 APs than 10/100/1000 ones

I’m now considering getting a different access point and… What access point are you using and what results are you getting?

We are using TP-LINK routers and switches. Never had any problems.

What is problem??

Connection fail?? or disconnection during data transferring??
