This.... This right here is the biggest annoyance of many with this product line.
I finally initiated a return on the Meraki Go gateway this morning because of this issue. I pay for 450 Mbps internet, and with this device, I was only getting 250 Mbps. Most of the time, it wasn't an issue. However, when my kids are both home playing Xbox and watching Netflix at the same time, and my wife and I are wrapping up work and watching a show together, it just isn't enough for all of us to do what we want to do seamlessly. The fact that I was being held hostage by my gateway was a huge concern, I just hoped it wouldn't become an issue. Unfortunately, it did.
Also, it seems that the Meraki Go line in general is sort of DOA. Support takes 3-4 days to get back to you and it is email only (read: pretty much useless). The lack of any real customizations just makes this product far too basic than even your $100 Linksys device you would buy at Walmart and the interface is difficult to navigate to boot.
I am a huge fan of Cisco and Meraki products and was hoping for far more than what this product offers. It just seems like a solution that was thrown together at a bar on the back of a napkin and was abandoned after launch. I will be working with my Cisco Rep to figure out an affordable way to get some actual Meraki units for my setup and shipping all of my Meraki Go products back eventually. In the end, it just isn't worth the amount of frustration it has caused me and my family in just a few short months.
