Yes it is possible. Yes it is safe. No you don't need to buy a new 'modem' (BTU).

Turn off the wifi on the Netis.

Plug in a cable from your new router to any port on the Netis that is already working for internet (test with a laptop and cable or something if you're not sure).

Configure wifi on the new router. Turn OFF DHCP on the new router (you can turn off DHCP on the Netis instead, but need to know what you're doing. I have experienced sometimes my HyppTV STB gets IP from my router's DHCP... )

It was an AP actually. Just using the word router to not confuse the TS. I agree that an AP would better suit his needs.

In any case, it's a moot point since TS stated he already bought a router.

That's fine. I wasn't suggesting you buy anything, save your hard-earned money for something else. Although the reasoning for going for an AP rather than a router is not about signal strength but rather reliability and (most of the time) cheaper price. Edit: Oh and flexibility of placement.

I am confused though, about what your question really is. It now looks like you want to configure your Netis to be your modem? Your original question implied that the Netis was the modem you got from TM and (again my assumption) would have already been configured by TM during installation?
