I’ve just completed the install of a new Max Transit CAT 18 modem with a Puma antenna. My speeds in the last 24 hours have been wildly inconsistent, ranging from .25mpbs to 45mbps! It usually hovers between 6-10. I’m in the middle of Phoenix, I cannot think of what might be causing the wide range. Is there any way to diagnose this?
Also is it normal for this unit to run at 130 degrees? I took it’s temperature and it’s nearly too hot to touch but is in an open space. I feel like I need to mount it to a heatsink.
Hi Chaoslos,
Maybe your area is saturated? If the cell tower is saturated, you’ll find that they will reduce your bandwidth.
130 Farenheit? Or Celsius? 
It should be fine if it’s Farenheit, but if you can ventilate it or get some cold air to it.
I had similar results that appear to be related to some DNS settings. I am not a network person but know enough to confidently make bad configuration changes which later complicate my life - especially when I have forgotten I made them. I think it was enabling the DNS proxy which was wreaking havoc with my connection, causing radical latency issues and ultimately making my internet unuseable. I also noticed the router was getting hot even though CPU was at lower levels. I now have DNS servers defined, disabled DNS proxy and have DNS caching enabled. Again, it could have been something else that I accidentally adjusted but now everything is running like a top and the router is at room temperature.
