Trying to avoid Spectrum's Wifi Charge - using my own router results in 1/2 the performance of their modem/router combo unit.

Here's the fee I'm complaining about - https://awesomejelly.com/time-warner-spectrum-wireless-fee/ (adblocker advised).

I am on the Spectrum 200/10 plan (standard internet speed now in my area). I get very good speeds using their provided Ubee modem/router combo equipment [DVW32CB - user guide, in-depth config, etc](https://www.timewarnercable.com/content/dam/residential/pdfs/support/internet/ModemUserGuides/ubee-dvw32cb-userguide.pdf). I have access to config this modem/router using 192.168.100.1 on my WAN.

Performance on this equipment is very good, wired or wireless. Here's a [dslreports speedtest link](http://www.dslreports.com/speedtest/36543581) to those results. Over my own router, I get about 95/10, sorry no link forgot to grab it and am posting away from home. These tests were performed over both wifi and ethernet connectionwith the wireless radio on the opposite equipment turned off for best performance either way, so wifi interference is not a factor in these results. Results were very similar for either wired or wireless.

Basically, upload is not affected on my own router apparently, but the download speed goes from over 200 on Spectrum's modem/router, to under 100 on my router. I'd like to get that 200/10 speed on my own router.

I'd like to run my own router [\(Asus RT AC-1200](https://www.asus.com/us/Networking/RT-AC1200/)) and disable the wifi in the provider Ubee modem/router combo which Spectrum provides to avoid any signal interference. They don't charge for modems anymore, but do charge $5/mo. for "wireless fee". I'm sure they still charge for modems, but rolled it into their overall bill to prevent people from buying their own modems. I have my own modem, but am not using it currently seeing as there is no financial benefit. I could try to use it, but this would require me to call them up, have the MAC address linked to my account, and even then, the results may not be any better than I have today (see below).

------------------------------- **TL;DR**

Is there something I can do to configure my ASUS router or the provided Ubee modem/router unit to get full speed out of the ASUS router? Do I need to configure it as an AP? I'm trying to understand why I get about exactly half the speed through the ASUS router as opposed to the Ubee modem/router unit.
