Query: Frustrating

I do not recommend this dual wan router. The advanced features tend not to work as advertised. If you want something cheap that will switch over to a second WAN this is it.Load balancing locks up your browser, it does not double your throughput. DMZ ends up not being able to ping or do anything. Yes, I upgraded the firmware to the latest level.I think there will be a big need for people who must always have internet on even if one provide drops out, unfortunately this router is not it.I used a peplink balance 200 it worked wonderfully, this router is a constant frustration.
