re: Can someone explain to me how to add a better router to the default combo ATT gigapower

Wi-Fi by current definition cuts your speeds in half

Not sure why you think this. Your WiFi is rated based on spectrum (2.4ghz or 5) and the standard (b/g/n/ac). Also some workers wireless routers use multiple channels across the spectrum to get even higher speeds, some closing in on 1 gigabit in real tests.

It uses radios to communicate back and forth in half duplex mode (meaning it can transmit or recieve, but not both at the same time). Wired Cat 5 and 6 can operate in full duplex (talk and recive at the same time)

Technically true, but the end user won't care.

I've read that they are devolping radio antennas for Wi-Fi that can do full duplex, but who knows how long that will take to come to market.

They already exist, but are costly custom solutions that typical consumer will want.

. To add an access point means cutting your speeds in half again.

Not true. It all depends on the current operating conditions. Bandwidth available is dependent upon what other devices are currently operating in the same spectrum, and the technology you are using.


To the original OP, unfortunately I do not know how to modify the settings of your ATT fiber equipment. If possible you would want to either disable it's routing capabilities or use it as the main router and use another access point. However the problem depends on what type of router att is using. The wifi might only be rated for say 380mbit or so. Which is way overkill for almost any use.

If you really want gigabit wifi speeds, you will need to bypass the att WiFi, and put into a bridge mode. Then make sure that you can connect from your ATT to your gigabit capable 802.11ac/ad router. Most of these routers will use a three antenna setup to get the extra throughout.
