No, you get what you get.
You can maximise settings, but you’re always limited to your line.

First thing to do if you are on a home wireless network is GET WIRED. Latency in wireless is terrible no matter what you do. If you dont believe it, prove it to yourself by running a test right next to the access point. Keep testing from different distances

depends…

here is a quick test to see if the noise is coming from your DSL modem… turn the DSL modem off, or disconnect if from your phone line.. if the static goes away, then you need to ensure that EVERYTHING connected to your phone line EXCEPT the modem has a filter on it… including all phones, fax machines, satellite boxes, your alarm system.. etc…

if you still hear static then your best option would be to bring a corded phone out to the NID on the side or back of your house and connect the phone there to see if there is still static.. if it is still there, then the problem is on the line outside and you need to call your local service provider to come out and make the repairs. if the trouble goes away, then there is a problem inside your home somewhere… check the jacks for water damage (greenish or blackish color on the jack contacts and line cord plugs) or loose wiring..

Sounds like Interference so you could have a dodgy cable or what do you have connected to your splitter.

Yes! This exact same thing is happening with my computer. I can’t play any of my MMOs because the latency is awful. I have to repair my connection about 5 times in fifteen minutes. I’ve also called about three times the past two days, but they keep telling me that there is no problem.

I really have no fix for this…but I’m kind of happy I’m not the only one experiencing this problem.
Oh! And I live in southern Alabama, so…

Yes!

The following link is the setup guide for your modem/router.

Section 7 give detailed instructions how to setup the router for whatever ISP to which you subscribe.

You may have to reset your router to the factory default first to clear all the Verizon DSL service information.

you can use direct pc to pc networking, and other computer can access internet

Ya, you can use it.

Buy a small switch or make your 1st computer as a access point(wifi).

I think, you need to get switch. For best performance, i recommend to cisco switch. I usually shop at:
