We don't provide support for any routers other than the ones that we rent and manage as we can log into them and make adjustments to help you if you are dealing with interference or other issues. If you are providing your own router we will assist to make sure you have the proper settings so that you can setup your router. But we cannot provide any support for the wireless or wifi settings. If you are providing your own router, you need to get support for it from the router manufacturer.
At a minimum, we recommend dual-band 802.11ac (WiFi 5 or WiFi 6) routers. These types of routers support both 2.4Ghz and 5Ghz. And due to the amount of interference on the 2.4Ghz band we recommend connecting on the 5Ghz band whenever possible.
The N300 and N600 are single band (2.4Ghz) routers that haven't been manufactured in quite awhile. So we cannot provide any assistance or support for it and we highly recommend against trying to use it or any single band WiFi router for that matter.
